LED integrated business screen is a new type of information display media, it is the use of light-emitting diode dot matrix modules or pixel units composed of a flat display screen. The figure shows the structure of the 8 × 8 dot matrix LED display, from the figure, the 8 × 8 dot matrix requires a total of 64 light-emitting diodes, and each light-emitting diode is placed in the line and column line intersection, when the corresponding line set high, a column set low, then the corresponding diode lights up.
For example, to display text, you can follow the composition of the text of the stroke that will be lit by the corresponding diode, to achieve the purpose of displaying text, as shown in Figure 3. The complete dot matrix can be composed of 16×16, 32×32, etc. display modules.
Each pixel of single color LED integrated business screen is composed of 1 single color LED light-emitting diode, that is, each pixel contains 1 LED light-emitting diode; each pixel of a dual-color LED display is composed of 2 LED light-emitting diodes of 2 single colors, that is, each dual-color pixel contains 2 LED light-emitting diodes; and for three-color full-color LED display, the diodes that make up the pixel points include For three-color full-color LED display, the diodes that make up the pixel points include 3 or more, such as by the 3 diodes that emit red, green and blue light respectively so that the purpose of the color display can be achieved according to the color matching principle of three primary colors; and some displays may consist of 4 diodes to improve the display effect: 2 red LED, 1 green LED and 1 blue LED.
When turning on the screen: turn on the machine first, then turn on the screen.
When turning off the screen: first turn off the screen, and then turn off the computer.
(First off the computer does not shut down the display, it will cause high brightness of the screen, led burned lamp, the consequences are serious.)
