LED display screen is a new type of information display media. It is a flat display screen composed of light-emitting diode dot matrix module or pixel unit. Figure 2 shows the structure diagram of the 8×8 lattice LED display. According to the figure, a total of 64 light-emitting diodes are needed for the 8×8 lattice, and each light-emitting diode is placed at the crossing point of row and column lines. When a row is set to high level and a column is set to low level, the corresponding diode will be lit.
For example, when you want to display text, you can light up the corresponding diodes according to the strokes that compose the text, so as to achieve the purpose of displaying the text. The complete lattice can be composed of 16×16, 32×32 display module.
Each pixel of a single primary color LED display is composed of a single color LED light-emitting diode, that is, each pixel contains 1 LED light-emitting diode; Each pixel of the dual-primary color LED display is composed of two LED light-emitting diodes of two monochromatic colors, that is, each dual-primary color pixel contains two LED light-emitting diodes. For the three-primary color full-color LED display, the diode composed of pixels includes 3 or more than 3, such as red light, green light and blue light by the three diodes, so that according to the principle of color matching three primary colors, to achieve the purpose of color display; Some displays, for better display, may consist of four diodes: two red leds, one green LED, and one blue LED
