LED display driver products mainly include row scan driver LED IC chip and column driver chips. It is widely used for outdoor LED display, indoor LED displays, bus station displays, and LED poster. In terms of display types, it covers single color display, dual color display and full-color LED display.
In the work of LED full-color display, the function of driving IC is to receive the display data (from information sources such as receiving card or video processor) in accordance with the provisions of the agreement, internally produce PWM and current time change, and output PWM current related to brightness and gray refresh to light up the LED. one of the biggest characteristics of special chip is to provide the constant current source. The constant current source can ensure the stable driving of LED and eliminate the flicker of LED, which is the premise of the high-quality pictures on the LED display screens.
IC Repair procedure:
At LED-ResQ, we utilize a detailed process for identifying and fixing problems with LED IC modules that ensures both precision and accuracy in each repair process.
Initial Assessment:
The repair process begins with a complete review of the LED IC module. The device is carefully reviewed so that we can clearly see anything physically wrong with the module, or anything that may seem to be acting abnormally.
Diagnostic Analysis:
After the initial assessment, our expert LED IC technicians move to a professional diagnosis to identify the root cause of the issue. We are known for our equipment and unique testing methods that helps us get in depth of the module and reveal the cause of the failure.
Component Repair or Replacement:
After the diagnosis is complete, our certified LED IC technicians begin the repair and/or replacement phase. Whether it be the IC chip, capacitors, or other integral items on a PCB that are causing the failure, our techs have the experience and expertise to carry out the tasks, and handle it to industry code.
