1. LED pixel module: LED is arranged into a matrix or pen segment, prefabricated into a standard size module. There are 8*8 pixel modules and 8 -character 7 -segment digital modules commonly used in indoor display. The outdoor display pixel module has 4*4, 8*8, 8*16 pixels and other specifications. The pixel module for outdoor display screen is also called a pipeline bundle module because each pixel consists of two or more LED tubes.
2. Full color: red and green double base color plus blue base color, the three base colors constitute full color. Since the technology of full -color and the technology of pure green tube cores is now mature, the market is basically full color.
3. Resolution: The number of LED display pixels is called the resolution of the LED display. The resolution is the total amount of the display screen, which determines the information capacity of a display.
4. Grayness: Gray is the degree of light and dark changes in the pole. The grayness of a base color generally has 8 to 12. For example, if the grayscale of each base color is 256, for the dual -based color screen, the display color is 256 × 256 = 64K color, also known as the screen as a 256 color display.
5. Pixel (Pixel) and pixel diameter: Each of the LED light emitting unit (point) that can be controlled separately in the LED display is called pixel (or elephant). Pixel diameter 每 refers to the diameter of each pixel, and the unit is millimeter.
6. LED brightness: The brightness of the light -emitting diodes is generally represented by luminous intensity, the unit is the CDla CD; 1000UCD (Micro Candra) = 1 mcd (millana), 1000mcd = 1 CD. The light strength of the indoor single LED is generally 500UCD-50 MCD, while the light strength of the outdoor single LED should generally be 100 mcd-1000 MCD, or even 1000 mcd.
7. Double -base color: Nowadays, most color LED displays are dual -based color screens, that is, each pixel has two LED tube cores: one is a red light tube core and the other is the green light tube core. When the red light tube is brightened, the pixel is red, the pixel is green when the green light tube is bright, and the pixel is yellow when the red and green tube core is bright at the same time. Among them, red, green is called the base color.
