LED Sign Tech and Spec: Own It! Be The Trusted Authority on LED Signs and Educate Truth.

-Scott Hofheins

As tech savvy as the world is today, LED sign technology is still uncharted territory for many people. Unfortunately, there are those in the industry who take advantage of this, bending the truth to suit their needs without much thought to the end users long term experience. I don’t see these bad apples going away anytime soon, so it’s up to the rest of us to set the bar and educate the truth to as many people who will listen. This means working a little harder on the high ground and resisting the temptation to take the easy way out by lowering the bar.

Take the extra time to educate a potential buyer on why you can’t quote an LED sign with an active matrix of exactly 5’ x 8’, or a sign with 100 Quadrillion colors. More importantly, why the other guy can’t either. You are the expert, you are the authority. Own it, and use it.

Authority can be defined in a couple of different ways. Some people are perceived to have authority, so others follow regardless if they actually know what they are doing. Others may have expert knowledge of a subject, but are not perceived to be the authority and are consequently not followed.  If you were to just look at these two aspects, the choice is easy: be the perceived authority and make the sale. However, the third and most powerful option is to be both. You are the authority, the expert, AND a great communicator rolled into a trusted “go-to guy” for LED signs.

Communication and Trust are key concepts. If you can communicate your expert authority effectively, the people will trust you. They will respect your dedication to the truth and will be more likely to believe you over the other guy, as long as you can communicate on their level. Mike and Deacon both have posted some great advice on this subject, and are both very good communicators and trusted authorities themselves.

Being a trusted authority doesn’t mean you have a perfect knowledge. If you are trusted to provide accurate information, then do it, even if it means admitting that you need to confirm with a team member or consult a factory rep. People feel comfortable with a single point of contact who isn’t afraid to do this. It builds trust and confidence that your pride won’t get in the way of accurate information.

We all win when the industry is promoting truth. This might be difficult to see in the short term, especially if you’ve ever lost a sale to a competitor selling and LED sign with the solution to world peace. But history has proven that when industries work together to build trust, growth follows rapidly as people feel more comfortable to invest their hard earned money in products of the industry.

The willingness to sacrifice a little individually to grow and flourish as a group is one of the keys to a civilized society and exemplifies the best in humanity. Our industry goal should be to sacrifice the “win at all costs” mentality to produce a better educated customer, higher quality products in the market, and ultimately more sales for everyone. Own your authority, educate the truth, and help the industry grow by walking the high ground and raising the bar.

Digital Signage Sales 101: Wow Your Customer

- Mike Prongue

As a regional sales manager in this LED sign industry I walk into a lot of LED sign shops in the Southern USA. I dislike the term “shop” to describe a storefront since I always thought of a “shop” as a low tech place where a cobbler beat a heel onto a shoe or someone strung beads onto a wire. 

Since the product we sell is electronic and “techie” to say the least, I’d expect the “shop” to really be a “store”, perhaps like a single cell version of a “Best Buy”.  Let’s pretend how your shop/store would differ if it were actually fined-tuned and perfect in execution of some simple ideas? 

I present the “top 10” things to do to wow your customer with a great first impression of your shop/store:

• Walk the Talk   If you sell LED signs, have an LED display. If it does drive 15% more customers through the door and you aren’t using one, what’s the problem? Your LED sign is your best demo unit. Show customers the wireless RF, show them the computer and show them how easy it is to use! Oh, yours is tough to use? Shop around for another manufacturer. Not all LED signs are alike.

• Shop Shirts    Baseball teams, army units, and Olympic squads all wear a common uniform. Where is your “Dale’s LED Signs” shirts for your team? Identity is important. How about magnetic signs for the cars and window tinted logos on the cars? Get everyone into the same boat and start “rowing in the same direction”.

• Greet Customer  Quickly  Sour-faces need not apply. Someone needs to say “Hi, how are you? I’m Dave and I’ll be with you in one second!” Phones need to be answered by the 3^rd ring saying-“Dale’s Signs, this is Judy, how may I help you?” at the very least!

• Create a Nice Break Area  The single-most unprofessional thing a small business can do is have food scattered out across the counter area. That Italian sub with the stinky cheese may be your favorite treat of the week, so take it into the back room. Even better go out to lunch- you need the break. When you come back from lunch, grab the vacuum cleaner and vacuum that carpet. It’s been 6 years since anyone took that task on (in some cases).

• Have “show and tell” product displays  Have a hands-on area that displays LED modules of different resolutions, a power supply, an IPC (industrial PC). Why not educate your customers while they wait for help? Some LED sign stores have actual functioning LED signs on display of different resolutions.

• Watch your Language  Do not use any bad language. Reserve your political opinions to your evenings in front of FOX News or MSNBC on your TV at home. Regardless of what you say, ½ your customers may be offended. Watch your jokes. Take down objectionable posters. What’s funny to you is not so funny to Reverend Jones looking for an LED sign for his church. Do not create a hostile place of business. What about those angry “no soliciting” signs plastered all over your door? Does that apply to Girl Scouts and the local High School band selling doughnuts? What a Scrooge. I wouldn’t buy a sign from you.

•  Create a Customer Service Area  Many LED sign stores are engaged in traditional sign businesses and have layout areas and drafting areas and other in the front of the store. Some of this is unavoidable but “hide the chaos” as much as you can and create a simple neat and clean area where customers can be greeted and talked to. Even the use of a couple free-standing, cubicle-used, room dividers can separate the customer area from the work area.

• Clean up the Production Area  Have a mandatory 10 minute break, once in the morning and once in the afternoon and clean up the production area. Customers are judgmental and may think the mess you create in your own work area is what you may do at their facility. With a clean production area, you can show your handiwork and skills to customers on safe, guided walk-throughs.

• Have a Website  Yes, you can fool some of the people some of the time, but you’ve had that “under construction” message on your website for 2 years now. This is 2013 and a website is an electronic you- a presence that the world can access 24-7. I can’t tell you how much a good website improves business credibility. Conversely, a minimal website shouts a different message to the world, perhaps an unintentional message. Google Adwords used within a region is a very successful new customer strategy. But they have to visit a website that is interesting and professional.

• Sundown Rule Time waits for no man, or woman. Your urgency is one of the variables that can win you customers. The old Zig Ziglar saying is “People don’t care how much you know until they know how much you care!”  The way to show people you care is to reply to their inquiry, finish their quote, or call them back. Don’t let issues extend into the next day- solve the problem now so you can sleep better tonight!

What I’m suggesting is turning up the heat and creating a friendly, neat, clean and impressive area to wow customers and to do business.

A lot of businesses are simply amazing with their execution of these 10 items and dozens more. Remember you only have one chance to make a good first impression.

You create your own reality so wouldn’t it be better if you had an store that people remembered in a good way?It doesn't take much work. Get your team involved and ask for suggestions on improving the customer experience.

LED Sign Tech & Spec: Factors Affecting Image Quality on Outdoor Digital Signage

-Scott Hofheins

I’ve been actively evaluating virtually every LED sign I happen to see for quite some time. Its almost an instinctual reaction to immediately determine the manufacturer, quality, size, pitch, etc... This is a common affliction that affects most people in the industry and is a running inside joke.  We are constantly being told (usually by our significant others) to stop looking at the LED signs, and start paying attention to the world around us. Although this may be a long term issue for us, it can be a great temporary issue for those looking to find a high quality LED sign. The aspect I’m going to focus on today is: Why is there variation in the image quality on an LED sign and what are the factors that affect this quality?

The LEDs

An LED display is really just a large group of individual LEDs laid out on a grid, like your computer monitor or TV. Individual LED’s come in many colors, shapes, sizes, configurations and quality. These factors all come into play when dealing with the image on an outdoor digital sign. High quality LED’s that are matched correctly will significantly improve the image displayed.

LED manufacturing is not perfect, and every LED manufacturer must deal with a certain variation of color from LED to LED. The method used to organize LED’s with the same color is typically referred to as “binning”. LED’s with the same color output within a certain tolerance will be put together. This is very important for both  indoor and outdoor digital signage because they are using so many LED’s that if you didn’t bin correctly, the display would look “blotchy” from the different shades of Red, Green or Blue LED’s spread out across the entire unit.

It’s important that the manufacturer address this and can reliably replace LED panels with LED’s in the same “bin grade” as the rest of the sign. You can see this pretty clearly on a display that has one or two squares that are “tinted” against the rest of the sign.  Unfortunately this usually means that the manufacture wasn’t able to provide a matching LED Module (or panel) and the business had to settle for the best of two evils, have a blank square, or a “tinted” square.

Module Construction and Mounting

LED displays are built using groups of LED’s mounted to an LED Module, or panel. These panels will hold multiple LEDs, usually in grids or 8x8 or 16x16 pixels. These modules also house some of the hardware and circuits that control and drive the LED’s on a fundamental level.

The construction of these modules is very important to the quality of the image. Just like mismatched LED’s, modules that are not uniform in construction will create an inconsistent image across the display. This situation will cause a “patchwork” effect, where you can see the individual modules seams, making it look like a patchwork quilt. This may not be noticeable from directly in front of the display, but as you move to the side, you will quickly see the quality difference when lines start appearing out of nowhere.

The module mounting system and cabinet design are also factors manufactures have to consider. A mounting system that doesn’t uniformly pull the LED’s onto the cabinet can cause some of the same effects I mentioned above. The cabinet design must also be consistent. An uneven cabinet will make for an uneven display.

Louver Panel Design

The LED’s must be shaded from direct sunlight.This might sound odd to someone new to the industry, but it is true. Fully exposed LED’s will be washed out by the sunlight and their effectiveness diminished. Louvers are put in place to shade the LED’s from the sun and isolate the light, but not block the visibility of the sign itself. This provides higher contrast by giving the image the blackest surface possible.  

The design of these louvers is important. If the louvers are too small, they won’t shade enough. If they are too big, they might block the view of the LED’s above. The material of the louver panel is also very important. A Flat black non-reflective finish that absorbs the light will improve the contrast and the overall depth of the colors.

Additionally, LED’s in a pixel group (a group of Red, Green and Blue LED’s) will have at least one LED that is physically positioned lower than the rest. Well designed louver panels should shade each LED, not the entire pixel group. Some manufactures are also using “mini” louvers that help divert even more light from the panel surface itself.

Brightness and Contrast

These two principles go hand in hand on a quality display. The display has to be very bright during the day, but it also has to maintain contrast. The blacks must be black, and the whites, white. The contrast is physically determined by the louver face and LED panel design. As I mentioned before, flat black louver panels affect this. The brightness aspect is determined by the LED’s themselves, and how hard they are “driven”. High quality LED’s can be “driven” brighter without a significant loss of life. However, some sub par manufacturers will drive lower quality LED’s harder, and they might be bright at install, but start to fail quite often, over time.

Color Calibration

This relates to the Brightness and Contrast mentioned above, but also includes Color. LED signs need to be calibrated to make sure red is actually red, or chartreuse is actually chartreuse. This is done by calibrating the video signal, and the internal hardware at the factory. Unfortunately there are still manufacturers out there, usually overseas direct, that do a poor job of calibration.The result is an end user with an LED sign that will always look worse than the others around it, regardless of any software adjustments they make.

Content

This is a big one for me, because it is the easiest to control, yet many people don’t realize it’s importance. Good content can make a lower quality sign physically look better than a high quality sign. This is an unfortunate truth that many dealers have felt directly when a customer sees a sign with great content, and decides to use that manufacturer for that reason alone. They are then stuck with a sign that might look great for a couple of months, or maybe a year, but will soon start to fail, over and over again.

Remember, it’s not enough these days to just have an LED sign, it has to look great too. If you're looking into an LED sign, start investigating the ones around you. Note what looks good, and what doesn’t and do your research. Use this blog and the other great resources out there to make sure you get a sign that’s going to look good for a long time. It’s worth the extra effort to really get to know the industry yourself and be an informed buyer.

LED Sign Content: How 'LinkedIn' is Digital Signage for you/your clients?

-Deacon Wardlow

Digital Signage gets a lot of attention at the start. It's a new way to reach out to the community and DS often gets a lot of attention at the start. As things go on, the attention wains and waxes away. Like a good bike chain, a little attention every now and then keeps things moving forward smoothly, leave it alone too long and you'll soon be going nowhere with that new tool...

It's hard to keep up with content. most organizations and businesses don't have something new and astounding to grab people's attention every day/week/month. after a while the well runs dry and we turn to the "same old" for a go-to with the display(s). Once DS becomes stale, people stop paying attention and it's very hard to earn those eyes back once they've opted to relegate a display to the "background noise" of their daily life/commute.

Social media is a great way to keep content fresh and interesting, regardless of the organization. An LED sign can be a community rallying point. Interaction gains activity and interest. Put up a challenge of the week on the display (challenge placed in the beginning of the week, answer/solution later in the week). Have people go to a social media site to respond and post the winner's response on the display (with the prize). An LED sign can also rally around social issues/charities/causes and give people information to links online (keep the links short/memorable).

A dynamic display can be more than specials and basic messages. By tying-in to social media sites the organization can achieve more outreach, more connection with the community and an overall increased success rate with getting their message out (whatever the message is). When speaking with end-users, show them the message doesn't have to stop with the display itself, but can expand out to other areas. Like a bike chain, technology doesn't work well in isolation. Put all the parts together and you (and your clients) can really get moving with DS!

Digital Signs Need to Know- Is Anything Really ‘Made’ in the USA?

 - Mike Prongue

Can China compete with American manufacturing?  This legitimate question was raised a couple years ago in a Time Magazine article with the same title, by Michael Schuman (STORY) and I invite you to read it.

You may think of American manufacturing as simply rolling up into a “small ball of pity” and getting kicked around some dusty and abandoned factory floor somewhere in Ohio, by a team of aggressive Chinese workers. That is not true. China may be in the lead with total dollars output but that is not so surprising.

Markets are efficient and seek out the least expensive path, the path with the highest utility, to produce goods. Every country, including Japan and South Korea, has ridden the predictable economic life-cycle starting as an “infant” with only cheap labor, making simple products, to a maturing, high-tech, high-value, manufacturing adult. The USA has been a sophisticated manufacturing adult for over 50 years.  We design, engineer, assemble, QC check, evolve and market some of the most complex products and systems known to man. From sophisticated medical devices such as MRI systems, to devastating and futuristic weapons of war, to Boeing’s Dreamliner 787 jet airliner, the USA has the technology and capability that China can only lust after at this point.

The question this post asks is “anything really made in the USA”? The answer is sure- we make natural gas, oil, and iron ores as mining output.  Those items are made entirely in the USA as they have been dug up from American soil. There are also many other items, usually simple items that are totally made in the USA (although we can debate where the steel may have originated).

What about products that are comprised of multiple complex sub-components? What about Dell and HP, and Chrysler and Ford and GM and Apple… all icons of American manufacturing?  Do they “make” American products?

Some people say “yes, of course” while others say “no way”.

How can GM profess to have cars "made in the USA" when so many sub-components are made elsewhere in the world? How about Japan? Are Toyota and Honda American manufacturers too then, since they assemble so many cars here? Last look, Toyota Camry and Ford F-150 shared the top spots in the USA with Honda Accord taking the 3^rd spot for cars built in the USA (CARS). Well, are they taking the prize as the top American manufacturing  or not? Does anyone know anymore?

Does anyone care?

Here is what you need to concern yourself with:

•  American Designed and Engineered Who controls the drafting, design, engineering and quality expectations of the product? This is the most important part of the equation. Many times, an international component is used because there is no better product available. Certain sub-components may already be well-engineered and designed, but can be enhanced further with a beefed-up capacitor or a more sophisticated voltage regulator. This is where the “American designed and engineered” stamp determines the ultimate reliability of the product.

•   Manufacturing in the USA or controlled by USA quality teams If it’s not actually created  by American hands on American soil then it had better be produced in a foreign factory owned and managed by the American company. If the factory is not owned by the American company then having on-site quality control engineers present during manufacturing runs is essential. You get what you inspect, not what you expect.

•  Assembled in the USA If the well-engineered, USA designed sub-components are manufactured in a high quality environment, regardless of where the factory is located, integrated with other systems created and made in the USA, then assembled by American workers, this is a win-win. You’ll find that the proud USA airline manufacturer, Boeing, uses over 45 companies to produce its new 787 Dreamliner jet airliner. But it is assembled in the USA!

• Backed by USA warranty Okay, so now we have a high-quality system, designed to specification, engineered by experts, manufactured to exacting standards (somewhere), delivered to the assembly plant just-in-time, and integrated into the final structure. If it breaks and there is no rock-solid warranty behind it, it does not matter if it was made in front of the Lincoln Memorial or in a rice paddy in Vietnam. Having the surety of a warranty, preferably a 3^rd party warranty, one that transcends the manufacturer’s promise is a huge benefit!

• Supported by USA technicians and qualified  support people Having a product that can be supported by qualified USA technicians with “boots on the ground”; service conversations with qualified people who can support in the English language (and others); comprehensive product documentation that is not optional. Any manufacturer who wants to be taken seriously will have these available to customers.

It is a global business world. Do not be misled into thinking that any LED Sign company has a 100 percent horizontal manufacturing process where iron ore, trees (for paper), electronic components and screws are fed into the back door of the factory and a perfectly assembled LED sign comes rolling out the front. It just "don't work like that!"

Stuff comes from everywhere, made by everyone- doesn’t matter if it’s an LED sign or a Boeing 787 Dreamliner. You just have to do your homework and research the company, talk to their people, see their product in the field, and interview a few customers. 

The truth always comes to light. Just make sure it does BEFORE you invest in an LED sign.

Digital Signage How To: Basic LED Sign Troubleshooting and Logic

- Scott Hofheins

One of our main goals for this blog is to be a resource to the industry, regardless of the manufacture. In keeping with that spirit I would like to go through some basic LED troubleshooting principles to help those who are new to LED signs, or have found themselves with a broken sign or a manufacturer who is difficult to work with.

Although the quality and design approaches are different between manufacturers, there are some general concepts that most outdoor LED sign systems will follow. They include basic operating components working together to create a full outdoor LED sign system. Deacon has a great post with some good notes on making sure you’re getting quality components for these systems.  

Basic Components

• Controller: This is the brain of the LED sign and is typically the junction point for the communications, temp/light sensors, and video input and output for the entire sign.
• PC Based (IPC): These are typically internal (sometimes external) industrialized computers running a secure operating system. They are more powerful and tend to give a bit more flexibility to the system with regards to video display, troubleshooting and customization.
• Embedded Controller: These will look more like a circuit board and are typically used in systems geared for static text and images. Many will play animations and some video, but the frame rate and storage space is limited.
• Video Board: This converts the video signal from the controller into a readable format for the sign hardware. This board is sometimes combined with an embedded controller, but it usually separated on an IPC based system. Terminology can include: DVI Board and Sender Card.
• Logic Board: These translate the video signal from the Video Board, to the individual LED modules on the sign, usually in rows or columns depending on the manufacturer. These are sometimes combined with embedded controllers on value systems. Terminology can include:  Turbo Boards, Receiver Cards, Hub Cards, Row Boards, and Ribbon Boards.
• LED Modules: These are the actual panels of LED’s that make up the entire sign. They can range is size from 8x8 pixels to 16x16 pixels and larger depending on the pixel pitch (how close the pixels are to each other). The rear of the Modules will typically have the power and data connectors integrated. Terminology can include: Driver Boards, Tiles and LED Panels.
• Power Supplies: These power the internal hardware for the LED sign. They will usually take in AC voltage, and output DC voltage to the components. They will typically power more than one component or LED module.
• Temperature Probe: These are typically used to get outside temperature readings to display on the sign. These have been standard equipment on LED signs since the early days, but are used less frequently now as owners focus more on content and targeted advertising.They vary in appearance, from simple metal probes, to white “finned” apparatuses.
• Communication Devices: Many signs use secured Wireless communication devices these days, but many still use traditional wired solutions like Fiber Converters, and hardwired Cat5/6 Ethernet cable. 

Troubleshooting LED Signs.

Follow the Data Chain

LED signs rely on a certain amount of “daisy chains” to get data from one component to the next. Generally speaking, it goes something like this:
User’s Computer --- Communication Device  on Building --- Communication Device on the Sign --- Sign Controller --- Video Board --- Logic Board (These are daisy chained to other Logic Boards across the sign) --- Rows or Columns of LED Modules Daisy Chained together.

 
Keep it Simple

Look at your symptoms, and find a logical place to start ruling out causes of the issue. For example, if the sign has a module out, you wouldn’t start testing the communication devices. You would start looking at the LED sign hardware (LED Modules, Data cables, etc...). 

Make the Issue Move
When you are physically troubleshooting components, you want to either fix the issue or make it move. If you can make it move then you can isolate the component and replace or repair it to fix the issue.

Re-boot
Electronic devices sometimes get locked up and require a reboot to get going again. Cycling power to the sign can sometimes fix issues. However, you shouldn’t have to do this constantly. If so, then look for the root cause of the freeze ups.

Specific Issues with LED Signs

Sign is Blank

• Verify Sign is powered within specs.
• Check the other side. If it’s working you may have a communication or power issue between the functioning side, and the blank side.
• Check your schedule. Is content scheduled to be playing? An expired schedule is a common cause for a blank LED sign.  
• Can you communicate to the display? If so, then you know the controller is working and you can check other parts of the system.
• If it’s a PC controller can you log in and verify the “player” is running? If it’s an embedded system it may have some diagnostic features that will allow you to see if it’s physically playing data.
• Check the Video Board. Is it getting power? Is it getting signal from the PC and sending it to the other components? Check the Data Cables.
• Check the Logic Board, and make sure it’s getting power and data. Unless you have a looped system, a bad Logic Board at the beginning of the data chain can cause the rest of the sign to go blank.

One or More Sections of a Face Blank

• Verify power is supplied for the first section not working.
• Check the Hardware (DVI Board, Logic Board) that is responsible for the first section in the chain that is not working.
• Check the power supplies in that same section.

One or more LED modules out or “scrambled”

• Always start at the first module in data chain that is NOT working. Make sure it’s getting power, and getting data from the previous data source (LED Module or Logic Board).
• Check the module next to it that IS working. Sometimes the output is bad, or the data cable between the two is bad. Swapping these boards can help isolate the issue.
• If the module is getting data from the Logic Board, check the data ports and cable. Swapping cables will help determine if it’s a port on the Logic Board, LED Module, or just a bad cable.

Line or Linear Errors Across the Entire Sign.

• Double check the content. Make sure your file doesn’t have errors.
• Check the Logic Board. This is responsible for whole rows, or columns of LED Modules.
• Check the first LED Module in the series. On a smaller sign, it may be sending bad data to the rest of the row or column.

Errors and Display Issues with the Entire Sign

• Double check the content. Make sure your file doesn't have errors.
• Check the Video Board. This board is responsible for the entire video signal to the rest of the sign. Make sure it’s getting good data from the controller, and good DC power from the power supply.
• Check the controller’s video output. Sometimes a loose cable can cause video issues that will affect the entire sign.

Issues can seem complicated and difficult, but if you remember to think linear, keep it simple, and take a step by step approach you will find that they can be isolated relatively quickly. Even the best LED signs will have issues now and then, but remember the quality of the manufacturers design, components and support play a huge factor in how often this happens and how easy it is to fix when it does.
