With the rapid development of technology of LED display, LED electronic display screen and LED full-color displays, and so on but also presents the diversification development LED display products, LED display is now widely used in all walks of life, but for beginners, LED display a lot of professional term is don't understand, so DDW to answer for you what LED display common terminology?
1, LED brightness: general with the brightness of the light emitting diode luminescence Intensity (Luminous Intensity), said the unit's candela CD; 1000 the ucd (micro candela) = 1 MCD (candela), 1000 MCD = 1 CD. Indoor use only the LED light intensity is commonly 500 ucd - 50 MCD, and outdoor with single LED light intensity generally should be 100 MCD - 1000 MCD, even more than 1000 MCD.
2, LED pixel modules: LED array as a matrix or pen, prefabricated into the size of a standard module. Indoor display commonly used have 8 * 8 pixels module, eight word seven segment digital module. Outdoor display pixel module has 4 * 4, 8 * 8, 8 * 16 pixels specifications, etc. Outdoor displays with pixel module because of its each pixel is composed of two or more LED tube bundle, so it is also referred to as control module.
3 (Pixel) and Pixel, pixels diameter: each of the LED display can be individually controlled LED unit (or points) called pixels (or like). 30 pixels diameter refers to the diameter of each pixel, the unit is mm.
4, resolution: LED display pixel number of columns is called the resolution of the LED display. Amount of pixels resolution is display, it determines the information capacity of a display screen.
5, gray, gray level refers to the degree of pixel light emitting light and shade change, a kind of primary colors gray levels generally have 8 to 12. For example, if each of the primary colors gray for level 256, with double colors color screen, the display color is 256 x 256 = 256 k color, also known as the screen is 256 color display.
6, double colors: most of today's color LED display is double colors color screen, namely each pixel are two LED tube core: one for the red light tube core, one for the green light pipe core. Bright red light tube core when the pixel to red, bright green light tube core when the pixel is green, red and green light at the same time, the two tube core pixel is yellow. The red, green called gezer.
7, full color: red, green, double colors, combined with the blue color, the three primary colors, make up full color. Due to a full color blue pipe and pure green core technology is now mature, so the basic market with full color.
