Working Principle And Precautions Of LED Integrated Business Sc

  • Working principle of LED Integrated Business Screen

    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.

     

    Working principle of LED Integrated Business Screen

    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.

    Precautions Of LED Integrated Business Screen

    1. Switch Order Of LED Integrated Business Screen

    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.)

    2. The interval time should be greater than 5 minutes when switching the screen.

    3. The computer enters the engineering control software before powering on the screen.

    4. Avoid opening the screen in the all-white screen state, because the inrush current of the system is the largest at this time.

    5. Avoid opening the screen in the runaway state, because the inrush current of the system is the largest at this time.

    6. Electronic display body a part of a very bright line, should pay attention to timely shut down the screen, in this state should not be a long time open LED integrated business screen.

    7. Frequently, the power switch of the display trips, you should check the screen or replace the power switch of the LED integrated business screen in time.

    8. Regularly check the firmness of the hanging joint of the LED integrated business screen. If there is a loose phenomenon, pay attention to timely adjustment, re-enforce or update the hanging parts.

    9. When the ambient temperature is too high or heat dissipation conditions are not good, LED integrated business screen lighting should be careful not to open the screen for a long time.
