The following three methods are commonly used for testing TFT liquid crystal screens. Mobile intelligent terminal manufacturers can also conduct this series of tests on TFT liquid crystal displays when they receive them. The so-called true gold is not afraid of fire, and good equipment can withstand repeated scrutiny.
With the sale of TFT liquid crystal displays, TFT has become increasingly popular. How do I test TFT liquid crystal displays? I believe many friends are interested. Let's explain it to the editor of Xunrui Optoelectronic Technology.

1. Electrical measurement
Electrical measurement refers to the detection after inserting a TFT liquid crystal display screen into a computer motherboard or display screen test box. The key is to show whether the actual effect is Y-shaped, whether there are flash points, whether there are abnormalities, tone symmetry, residual shadows, missing lines, and other issues. Electrical measurement is a very core part of TFT liquid crystal display screen detection, which can generally quickly detect problems.
2. Experimental detection
The important part of TFT LCD screen detection is detection. Before shipment, general professional TFT LCD manufacturers will conduct reliability tests such as constant temperature and humidity equipment and 72 hour plug-in aging to ensure the stability and stability of the equipment. After passing the test, they will deliver the equipment to the customer.
3. Estimation
It is estimated that the outer surface is tested with both eyes in the middle, just to test whether the appearance is good, and whether there are any problems such as dirt, hand fluff, and dust. In addition, it is also necessary to test whether the TFT liquid crystal display screen surface has scratches, is easy to tear, whether the protective film on the surface is in the appropriate position, and whether there are required screen printing inks for the production date, model, and specification. The estimation method can be used for testing.
