Beijing time on July 13, news, China Touch Screen Network News, a brief analysis of the factors affecting the mobile phone TP touch screen, and the role of the shrapnel micro-needle module in the test. A TP touch screen must be installed on a smart phone to be able to operate. Like the display screen, the TP touch screen is an indispensable and replaceable component in the mobile phone screen. The TP touch screen consists of a touch detection component and a touch screen controller, and is generally fixed to the main board through a connector. 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 hub of human-computer interaction, the testing of TP touch screens is particularly important.
TP touch screen test
For mobile phone TP touch screen testing, a stable connection can be established with a shrapnel micro-needle module, and the testing efficiency will also be improved. The shrapnel microneedle module mainly has the characteristics of being able to deal with small pitches, transmitting large currents, and long service life in the mobile phone TP touch screen test. The integrated shrapnel design not only has high overall accuracy, but also has good electrical conductivity. In the high-current test, the shrapnel micro-needle module can transmit current in the range of 1-50A, with stable and smooth overcurrent, constant voltage, no current attenuation, and stable connection; in small pitch (≤0.3mm), it can be Respond to the pitch value between 0.15mm-0.4mm, no pin stuck, constant needle, has a stable and reliable solution, expression and life are far beyond other modules.
In the mobile phone TP touch screen test, the shrapnel micro-needle module has an average service life of more than 20w times, can well adapt to high-frequency tests, and maintain stable connection performance for a long time. Its shrapnel head has a self-cleaning design, which can avoid interference from impurities, greatly improving 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, is extremely cost-effective, and has short delivery time and fast shipping, which has obvious advantages.
The TP touch screen can be assembled on the mobile phone after being tested. The touch screens applied 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, can avoid the accidental touch of other items, and can realize the operation by directly touching it. 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 can be avoided and the service life of the TP touch screen of the mobile phone can be prolonged.
Factors affecting the work of TP touch screen
1. Environmental factors
The best working temperature of the mobile phone TP touch screen is 0~35 degrees Celsius, and the best storage temperature is between -20~60 degrees Celsius. When the working temperature is higher or lower, it will cause the mobile phone TP touch screen to drift. High temperature or prolonged exposure to the sun can also damage the TP touch screen of the mobile phone. Therefore, when the phone screen is hot, it should not be used again, and the screen temperature needs to be lowered.
2. Conductive material
Oil stains, sweat stains, and water vapor are all conductive substances. When these substances are attached to the TP touch screen of the mobile phone, the screen will drift and affect the use. If it penetrates into the mobile phone TP touch screen, it may permanently damage the touch screen.
3. Electrostatic factors
Static electricity will also cause damage to the TP touch screen of the mobile phone, because the capacitive touch screen relies on the electric field for positioning, so even a slight static electricity will cause the drift of the TP touch screen of the mobile phone, which requires special attention.
4. Magnetic field response
A magnetic field will generate an electric field, which will cause the TP touch screen of the mobile phone to drift and cause the screen to malfunction. Therefore, the TP touch screen of the mobile phone will also be damaged in an environment where the magnetic field is too strong, so it is not suitable to use the mobile phone.
5. Voltage Factor
In the case of unstable voltage or low voltage, it is very likely that the TP touch screen of the mobile phone will drift.
6. Other factors
Physical damage such as impact, vibration, etc. will cause irreversible damage to the TP touch screen of the mobile phone. Changes in ambient temperature and humidity, electric field, contact area, medium dielectric, etc. may cause the TP touch screen of the mobile phone to drift and malfunction, resulting in inaccurate touch. Or damage the screen performance.
