With the continuous development of science and technology, LED display has become an indispensable part of our lives. However, when the LED display fails, many people will feel helpless. So, how should the LED display be repaired? LCF Xiaobian will take you to understand the basic structure and working principle of LED display, and introduce common faults and maintenance methods.

First, the basic structure and working principle of LED display.

LED display is mainly composed of LED light beads, drive board, control card, power supply and so on. The working principle is that the image data is transmitted to the driver board through the control card, and the driver board converts the signal into the voltage and current required by the LED lamp bead, so that the LED lamp bead emits the corresponding light to form an image.

Second, LED display common faults and maintenance methods.

1.The driver board is faulty

The driver board is one of the core components of the LED display, which is responsible for converting the signal from the control card into the voltage and current required by the LED lamp bead. If the driver board fails, the LED display cannot be displayed normally.

Maintenance method: Check whether the power supply of the driver board is normal, if the power supply is abnormal, replace it; If the power supply is normal, check whether there is any phenomenon such as virtual welding or unwelding on the driver board. If so, repair welding is performed.

2. The backlight is faulty.

The backlight is another important component in the LED display, which is responsible for providing background light. If the backlight fails, the LED display cannot be clearly displayed.

Maintenance method: Check whether the backlight power supply is normal, if the power supply is abnormal, replace it; If the power supply is normal, check whether the backlight board is faulty or unwelded. If yes, weld the backlight board. At the same time, it is also necessary to check whether the backlight tube is damaged, and replace it if it is damaged.

3. The controller card is faulty

The control card is an important part responsible for the transmission of image data in the LED display. If the control card fails, the LED display will not be able to display images normally.

Maintenance method: Check whether the power supply of the control card is normal, if the power supply is abnormal, replace it; If the power supply is normal, check whether the controller card has hardware faults. If yes, replace the controller card.

4. The power supply is faulty.

The power supply is an important component responsible for providing electrical energy in the LED display. If the power supply fails, the LED display will not work properly.

Maintenance method: Check whether the power supply is normal, if the power supply is abnormal, replace it; If the power supply is normal, check whether the power output is stable. If it is not stable, adjust it.

Third, summary.

LED display is broken how to repair? Understanding the basic structure and working principle of LED display, as well as common faults and maintenance methods, can help us better solve the problems of LED display. In the process of using the LED display, it is also necessary to pay attention to regular maintenance and maintenance to extend its service life. I hope this article will help you to keep your LED display clear and bright at all times.
