What tests do you need to make for the lcm module?

LCM, the full name of LiquidCrystalModule, Chinese name for liquid crystal display module, is a high-tech basic component, which can be assembled with other components to form electronic products such as mobile phones and tablet computers. Currently, LCM needs to be tested before it leaves the factory. The traditional LCM test method is: placing the LCM to be tested on the test bench, and detecting the LCM by means of a manual handheld detection device. Since the detection method adopts manual hand-held detection equipment, the labor intensity of the worker is large, and the detection efficiency is low. Therefore, how to achieve effective fixing of the detecting device, reduce the labor intensity of the detecting worker, and improve the detecting efficiency are technical problems to be solved by the present invention.

First, the LCM test is divided into visual inspection and electrical testing.

Visual inspection: no power on visual inspection

Electrical test: check the display effect under power-on

Second, the test tool

Driver board, test stand, DC power supply, multimeter or similar measuring instrument
