LCD Touch screen For iPhone XS

                                       Analysis of the reasons and test methods affecting the TP touch screen of mobile phones

The TP touch screen must be installed on the smartphone to realize the operation. Like the display screen, the TP touch screen is an indispensable and alternative component of the mobile phone screen. The TP touch screen consists of touch detection components and a touch screen controller, which are generally fixed to the motherboard through connectors. The touch screen is the external screen of the smart phone. It is installed in front of the display screen. It can detect the position touched by the user and send it to the touch screen controller to execute the received instructions. Since the era of full-screen smartphones, TP touch screens have greatly simplified the operation of smartphones and brought users a simple and smooth experience. As the center of human-computer interaction, the test of TP touch screens is particularly important.

TP touch screen test

For the mobile phone TP touch screen test, a stable connection can be established with the shrapnel microneedle module, and the test efficiency will also be improved. The shrapnel microneedle module mainly has the characteristics of being able to deal with small pitches, transmit large currents, and have a long service life in the mobile phone TP touch screen test. The integrated shrapnel design not only has high overall precision, but also has good electrical conductivity. In the high-current test, the shrapnel microneedle module can transmit current in the range of 1-50A, the over-current is stable and smooth, the voltage is constant, and there is no current attenuation, which can maintain a stable connection; in a small pitch (≤0.3mm), it can To cope with the pitch value between 0.15mm-0.4mm, there is no stuck pin or continuous needle, and it has a stable and reliable solution, and its expressiveness and lifespan are far superior to other modules.

In the mobile phone TP touch screen test, the shrapnel microneedle module has an average service life of more than 20w times, which can well adapt to high-frequency tests and maintain stable connection performance for a long time. Its shrapnel head type has a self-cleaning design, which can avoid the interference of impurities and greatly improve the test efficiency of the mobile phone TP touch screen! The shrapnel microneedle module does not need to be replaced frequently, which can reduce the waste of materials to the greatest extent. It is extremely cost-effective, and the delivery time is short and the shipment is fast. The advantages are obvious.

The TP touch screen can be assembled to the mobile phone after being tested, and the touch screens used on the mobile phone are basically capacitive touch screens. The advantage of this kind of touch screen is that it can sense the current of the human body, and can avoid accidental touch of other items, and the operation can be realized by direct touch. The TP touch screen will inevitably encounter some influences during use, which will cause the screen to malfunction or drift. By analyzing the factors that affect the work of the TP touch screen, incorrect use methods can be avoided and the service life of the TP touch screen of the mobile phone can be extended.
