LED Signs and DisplaysLED technology has been around for a long time. LED stands for light emitting diode - basically it is diode (a standard electronic component) that emits light when a current flows through it. Early LED lights were red in color - you've probably seen them on digital clocks, calculators, and as indicators on various electronic gadgets. Over time, blue and green LEDs were also created, with practical, bright LEDs really just coming into their own in the last 10-15 years. These days we see LED flashlights and many other applications. And by placing the primary color LEDs close together (RGB) and mixing their outputs, you can create the illusion of any color, allowing for LED video screens and more. There are video billboards, huge LED video display screens at ballparks and arenas, places like Times Square, and of course all kinds of indoor and outdoor signs with scrolling colored letters and images (think airports, banks, etc.).
Indoor and Outdoor LED displaysSingle color LED displays are the most basic, and they often come with 32 gray shades allowing for better graphics and animation. You've probably seen signs in front of schools, businesses, banks, etc. with information or news scrolling across the screen. Most systems come with built-in time and temperature functions, but obviously the real value comes in being able to input your own custom messages -- normally you can input and store hundreds of different messages. The real high-end LED displays are the full color video displays. Outside you might see these as mini billboards along the highway, but indoors you've seen them in sports arenas and other locations. They can accept video signal inputs from DVD, video cameras, PC, VHS, and Cable sources, outputting brilliant color in 16.7M colors. HiTech Electronic Displays (hitechled.com) is a leader in this LED marketplace for more than 20 years, having handled more than 20,000 LED installations. They serve LED sign markets like airports, banks, gas stations, sports venues, and movie theaters. Their SunBlazer products cover the single color market, allowing you to display text from 3.5" to 23" tall, depending on the model. All the LEDs have a 100,000 hour lifetime (that's over 10 years if you are counting..) Their PhotoBlazer LED screens gives up to 32,000 colors for signs and animations, without real-time full-color video. VideoBlazer is the high-end LED display solution and gives you full video performance using a pixel sharing technology for amazing picture clarity. They also sell the simpler indoor LED signs. You can also check out TheLEDSignCompany.com if you are looking for high-quality LED displays and more than 20 years of experience (they are the number 1 volume LED dealer in N. America). They offer full-color displays, grayscale LED displays, and super highway displays. Their installation services include site surveys, pulling permits, full documentation and tech support, and engineering drawings -- basically covering you from start to finish. And you get a 5 year warranty. Stop by and read the dozens of testimonials from satisfied customers. Finally, check out AdaptiveDisplays.com as another reputable source for LED signs and displays (30+ years experience). Their MEDIAMaster Digital Billboards have to be seen to be believed (these things can weigh a few tons, and cost almost as much!), but they also carry all the standard indoor and outdoor displays you would expect, from classic LED displays to monochrome 2 line scrolling text to full-color displays.
A good source for answering your basic questions about LED displays (if we haven't already done so) is WatchFireSigns.com/EducationFAQ.aspx - they cover things like how much do LED signs cost, LED viewing angles, best LED messages for advertising, etc. -- good starting point if you need help. They also have a section called LED Signs 101 which will educate you in LED basics. They also make and sell color LED signs and monochrome LED signs (they've been in the sign business for more than 70 years..) Another site with good information about buying an LED sign is LedAuthority.com/10ThingsLEDSigns.htm - viewing distances and angles, budgets, zoning considerations, messages, etc. How much do LED signs cost?Most companies use LED signs and displays either to promote their business or to sell advertising. Either way, they are supposed to be a good investment of your money -- they are supposed to make you money and increase sales. So how much do LED signs cost? They start on the low-end for monochrome displays (scrolling text) at around $20-$25K for a 15 foot by 6 foot tall sign, or $10-$12K for a 12ft x 3ft LED sign. A really small indoor screen with scrolling text 24" long by 2" tall will set you back around $300. A larger 48" by 4" sign might run about $500. The price of LED signs is determined by size of LED display, resolution (how many pixels and how big the pixels are), color technology (video vs. monochrome). Keep in mind that prices vary by features and designs that you choose - you can contact most of these LED companies for price quotes or a sales call if you need information - most also offer online forms to fill out to get additional information.
