Shandong full color light emitting diode polarity two leads in the longer one is positive, it should be connected to the positive supply. Linyi LED display as long as the two leads some light emitting diodes, Linyi full color, but there is a projection of the uvula, Shandong LED display near the uvula lead is positive on the envelope. The smaller the dot pitch, the higher the pixel density, the more information capacity, the closer the Linyi outdoor color display for viewing distance. The larger spacing led display prices, lower pixel density, the less information capacity, farther Shandong full color for viewing distance. 5. The number of rows of pixels resolution LED display called LED screen resolution. Linyi LED display resolution is the total pixel display led display, Linyi full color which determines a display of information capacity. 6, LED display (LED Panel) The LED pixel module in accordance with the actual needs of the size of the assembly arranged in a matrix, Shandong door first full-color screen with a dedicated display driver circuit, DC power supply led outdoor display, software, frameworks and decoration etc., constitute an LED display.
