What is LED display
LED display is using LED as pixel light-emitting component, composed of arrays of LED emit red, green and blue light, thus forming a color screen. However, due to light-emitting diodes have large diameter, so the same color distance between pixels is large. display is usually only suitable for large screen display.
LED display set of microelectronics technology, computer technology, information processing in one, with its colorful, wide dynamic range, high brightness, long life, stable and reliable operation and other advantages, it become the most advantages of public display media. At present, LED display has been widely used in large square, commercial advertising, sports venues, information dissemination, news releases, stock trading, etc., which can meet the different needs of the environment.
What is LED-backlit display
LED-backlit display is LCD display backlight source apply LED to instead of traditional CCFL cold light tube. Liquid crystal imaging principle can be simply understood as external voltage making liquid crystal molecules deflection, barrier backlight source permeability and make light projection in color filter, then forming image.
Backlight module transition from CCFL to LED can bring many benefits, it make LED display brightness more uniform, the product power consumption more lower.
