ShuangLiu advertising company,

ShuangLiu advertising company LED luminous color and associated with the production material and technology of the LED luminous efficiency, globe at first all of blu-ray, behind plus phosphors, according to the different needs of users, adjusting the different light color, the widely used have red, green, blue, yellow. Because of the low voltage LED work (1.2 ~ 1.2 V), active luminous and have certain brightness, brightness in voltage (or current) regulation, and in itself, and impact resistance, resistance to vibration, long life (100000 hours), so in the large display devices, there is no other way of display and LED display. The red and green LED chips or tubes together as a single pixel of display screen called three color or double colors, red, green, blue three kinds of LED chips or tube together as a pixel display screen called three colors or full color. If there is only one color is called the monochrome or single color screen, make indoor LED screen pixel size is generally 1.5 to 12 mm, often using several can produce different colors of the LED tube core is encapsulated as a body, LED outdoor screen pixel size of 6-41.5 mm, each pixel is made up of several kinds of monochrome leds, common product according to the pixel tube, double color pixel tube generally consists of 2 red 1 green, three color pixels of tube with 1 red 1 green and 1 blue. Whether made of LED monochrome, double color or 3 color screen, need to display image pixels of each LED luminous brightness must be able to adjust, the adjustment of fine degree is the grey scale display. The higher the gray level, the more delicate the image is, the more colorful the color is, and the more complicated the display control system is. Generally, the color transition of 256 grayscale images is very soft, while the color of the level 16 grayscale is very obvious. Therefore, the color LED screen is currently required to be made from 256 to 4096 grayscale.
