What is LED electronic TFT Display Module and classified

LED electronic display by the tens of thousands - hundreds of thousands of semiconductor light-emitting diode pixels evenly. LED pixels of different colors can be manufactured using different materials. Currently the most widely used is the red, green, yellow. Blue and pure green LED development has reached a practical stage.
LED display can show changes in the numbers, text, graphics and video; not only for the indoor environment can also be used for outdoor environment, with a projector, TV wall, LCD screen can not match advantage.
The reason why LED widespread attention and rapid development, is inseparable from it itself has advantages. Sum up these advantages:
High brightness, low voltage, low power consumption, small size, long life, impact resistance and stable performance. Extremely broad prospects for the development of the LED current is moving higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability, full color direction.Coding System lcd module
LED display Category
1, color by color can be divided into:
Single-color display: single color (red or green).
Dual color display, you can display 65,536 colors: red and green dual-color, 256 levels of gray.
Full-color display: red, green and blue color, 256 levels of gray, full-color screen can display more than sixteen million kinds of colors.
2, by display Category:
LED digital display: display 7-segment digital tube, suitable for the production of the clock screen, such as interest rates screen, display digital electronic display.
LED dot-matrix graphic display: display device is composed by many evenly light-emitting diode dot matrix display module, suitable for broadcast text, image information.
3, by using the occasion:
Indoor display: the luminous point is small, generally ⌀ 3mm - 8mm, shows the general area of ​​a few dozen square meters.3.5 TFT display module
Outdoor display: the general area of ​​tens of meters to several hundred square meters, high brightness, can work in the sun, wind, rain, water resistant.
4, the light spot diameter by Category:
Indoor screen: ⌀ 3mm, Φ3.75mm, F5mm
