Performance Index and Special Test of Mobile Phone LCD Screen

The performance index of mobile phone LCD screen corresponds to the special test of LCD. It is required that the LCD screen must pass the test of various items before entering the assembly process of mobile phone screen. The purpose of mobile phone LCD screen test is to verify whether its performance is normal, and whether the screen has abnormal phenomena such as bad points, stroboscopic, black screen, white screen, crash, color distortion and so on. The test is divided into two forms: automation and manual. At the same time, the stress test should be performed in various scenarios to observe whether the mobile phone screen display and parameters are normal.

The mobile phone LCD screen and the motherboard are connected by a board to board connector. The interior of the mobile phone is highly integrated, so the pitch of the board to board connector is very small. It is just that the high current shrapnel micro pin module can adapt to the test in the field of small pitch, so it is needed for the mobile phone LCD screen test. In the small pitch, the minimum pitch value that can be adapted by the high current shrapnel microneedle module can reach 0.15mm, which can maintain stable connection without pin jamming, and has excellent adaptability and expressiveness.

The high current shrapnel microneedle module is an integrated design, with the characteristics of high overall accuracy, good connection performance and low impedance. In the transmission of high current, it can withstand a constant current of 50A at most, with stable overcurrent and no current attenuation. The average service life can reach more than 20W times. The head types are diverse, customizable and excellent performance.

When in contact with the board to board connector of the mobile phone LCD screen, the high current shrapnel micro pin module can use sawtooth shrapnel to connect the male seat and pointed shrapnel to connect the female seat according to its characteristics, so as to maintain stable contact, make the test go smoothly, and effectively improve the test efficiency of the mobile phone LCD screen!
