A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for lighting. Introduced as a practical electronic component in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet and infrared wavelengths, with very high brightness.
An LED is a Light Emitting Diode, like an electronics diode it lets electricity flow in only one direction. The little wire encapsulated in the epoxy center emits light when electricity flows from the Cathode (positive lead) to the Anode (negative lead). Photons are then released to travel to your eye which is detected by your rods and cones and sent to your brain, no matter what size!! An LED can last from 11 years and longer, far outlasting a standard bulb so you see why we use them for Fiber Optics. Faden Spectrum specially designs the LED chips, which could improve the chip uniformity. And outsource the package production to the most reliable supplier, then LED lamp raw material quality secured.
LED display is usually composed of LED cabinets, which are composed of LED unit modules/panels. The LED display is the final completed product for advertising or information displaying, it was composed by a certain rows and lines of unit LED cabinet; the unit LED cabinet was composed by module certain quantity of LED modules, each LED module was composed by 16*16/16*8/8*8/4*4/1*1 LED pixels; each LED pixels were composed by 1R/2R/2R1G/2R1B/2R2G1B/2R1G1B/1R1G1B.
Faden Spectrum has the full range of pixels, which could satisfy all of LED display clients demands.
Definition: In digital imaging, a pixel (or picture element) is a single point in a raster image. The pixel is the smallest addressable screen element; it is the smallest unit of picture that can be controlled. Each pixel has its own address. The address of a pixel corresponds to its coordinates. Pixels are normally arranged in a two-dimensional grid and are often represented using dots or squares. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color image systems, a color is typically represented by three, such as red, green, and blue.
Faden Spectrum cares every pixel, we treat every pixel as the most critical unit of our quality, and it is the case that supports our worldwide fame.
Pitch is the distance between each pixel on your sign. A pixel is a cluster of two, three or four LED lamps. The closer the pixels, the crisper and more lifelike your image will be. You can also treat pitch size as pixel size, just as how big the functional pixel size.
Faden Spectrum has the full range of pixel pitch from indoor P3 to outdoor P100. And we could specially design the customized pitch size if your project needs.
A module is a unit that composes of LED lamps, case, connections, PCB, mask, and plastic housing, which make a relative function unit that could be lightened up and be controlled and tested by software.
Faden Spectrum developed the micro-ventilation system, which could make the modules have much better heat dissipation, keep the modules working smoothly.
LED display cabinet is composed of modules, which supported by an iron or aluminum frame. For outdoor cabinet, it could be made IP67 (front side), IP54 (back side). LED display cabinets could be designed various kinds’ style, such as rental, fixed installation, and curtain, strip and so on. The LED display cabinet size could be customized according to client’s request.
Ingress Protection (IP) ratings are developed by the European Committee for Electro.
Technical Standardization (NEMA IEC 60529 Degrees of Protection provided by enclosures - IP Code), specifying the environmental protection the enclosure provides.
Usually, if your display has less than 50,000 pixels totally, we highly suggest you use virtual pixel. Real LED pixel is the physical LED pixel; virtual LED pixel is theoretically 4 times as real LED pixel. While it is just theoretically, actually, the real effect of the virtual pixel is not really 4 times better. It is only a much better, but not really can be 4 times better. When you LED display system is more than 512*320 pixels, actually you do not need to use virtual pixel if you plan to use the whole LED display for one advertising contents, but if you plan to divide a big LED screen into small parts or small sections for many advertising contents, the virtual pixel is still very necessary and useful for you to achieve much better effect.
Virtual pixels are in a class of their own. Every Virtual pixel contains 2 Red lamps, 1 Blue LED and 1 Green LED. Each LED is spaced out evenly to provide an even higher degree of clarity. Virtual pixel provides more shades of colors due to the many different levels of intensity combinations. Virtual Modules provide brighter pictures and videos. Virtual pixels are perfect for outdoor use in any condition. They provide great visibility during day and night.
Faden Spectrum is an expert of the virtual pixel; we supplied hundreds of virtual displays around the world. If you love it, feel free to contact us.
Dot by dot correction is a new calibration technology and will be the direction of future LED display industry. The much more improved color consistency & high fresh frequency make it be the only solution for high-level advertising need.
Faden Spectrum calibration technology could give you full operation on your LED display, which could recover your several-year-old LED display to brand new picture effect. If you want your old display to get a new image, contact us now.
Corresponding with the LED display best viewing distance, size, application & installation, there will be many optional product models fit for each specific project. ROI & Budget is also very important factors.
Best viewing distance refers to the distance from the front side of the LED sign, where the audience can see a whole, clear and natural picture of the contents on the LED display.
There are 2 ways to calculate the best viewing distance: one is by the pixel pitch, one is by the diagonal. There are also the reasons why there are different viewing distances for the same model LED panel, also different viewing distance for the same size LED display.
RCG & CON is the 2 most important LED display screen system is basically set up. For each LED display screen, it has only one RCG & CON file. If you lose it or break it, please contact ERALED service dept for the file again.
LINSN is the most commonly used controlling system so far. LINSN is one of Faden Spectrum’s strategic partners for years. If you have any question on the controlling system, Spectrum is always around you.
Product model, controlling distance & application is the main factors. One more point is that the synchronous control system always has much better viewing effect and more powerful function than the asynchronous controlling system.
Simple cabinet has no backdoors; standard waterproof cabinet has backdoors, etc. If you can make very good dustproof and waterproof system for your LED display, the simple cabinet is also a very economical solution when the budget is limited.
Faden Spectrum’s simple cabinet design is very lean, neat and tough, which could handle installation packing up. Our cabinets have extremely strict surface treatment, which enables high durability and nice looking.
How to choose the best servicing model for your LED display system?
Front maintenance has two means to achieve: module front maintenance & cabinet front maintenance. Rear maintenance has only one means: from the back door of the cabinet. When the display is very small, cabinet front maintenance will be more convenient.
Mostly, indoor series adopt scanning mode, while outdoor from P14 to P40 use static mode. The static and scanning display is the only 2 models currently. The static display used for P14-40mm, when the pixel pitch is smaller than 14mm, the main working method is scanning.
Brightness control is needed since the environment brightness level is changing during the daytime. If you do not adjust the brightness according to the environment, the LED display screen system will not have a perfect viewing effect.
There are two ways to achieve the brightness control: manually changing & automatic changing. The automatic brightness changing can adjust the LED sign screen system are brightness perfectly according to the environment brightness level.
Multi-function card can help the LED screen system achieve many functions, such as automatic False Alarms, fire &smoke alarms, brightness adjustment, etc.
Sending card, receiving card & hub card is the LED panel screen are parts of the controlling system. Sending card is installed in the controlling PC, is the data sending equipment and receiving the card is installed in each cabinet, is the data receiving equipment; hub card is installed together with each receiving card, is the data distribution equipment.
All the above composed the main necessary parts of the control system.
How to choose the corresponding control model for your LED display system(Need to expand further in future, not enough: What's the difference between remote control and wireless control?)
Remote control & wireless control is very necessary when the controlling HQ is far away from the LED display screen system.
Remote control & wireless control is by IP address and internet/intranet system to achieve.
