                                                   Reasons and solutions for physical damage of mobile Phone Touch Screen

The touch screen of a mobile phone is also called a touch panel. It is an inductive liquid crystal display device that can receive input signals such as contacts. Some consumers have bought a new mobile phone and used it for only three days before the touch screen of the mobile phone fails. In the end, what is the reason for the failure of the touch screen of the mobile phone? Let me introduce the reasons and solutions for the failure of the touch screen of the mobile phone.

Now that the screens of mobile phones are getting bigger and bigger, once they come into close contact with the ground or other hard objects, it may cause regrettable consequences! But sometimes, after a fall, there is no superficial damage but the touch cannot be touched. What should I do? Of course, if it is broken, please find an after-sales repair point as soon as possible.

1. The touch screen and buttons of the mobile phone are all out of order (some of them are normal when they are turned on, and then they all fail)

Reason: It may be that the touch screen or some original parts are loose or damaged

Solution: Add soldering or replace the touch ic, add soldering or replace the cpu, write software (key failure, normal touch generally means that a certain key is stuck)

2. The touch screen of the mobile phone fails, but the buttons are normal

Reason: The touch screen is loose or damaged

Solution: It needs to be sent to a maintenance station for repair or replacement. You can change the touch screen, add soldering or change the touch ic, install the cpu (processor), check for broken wires or short circuits. (Normal use of software and cpu is also broken, but rare)

3. The touch screen of the mobile phone is off, which can be corrected, but it is still off after calibration

Solution: Restore the factory or check the grid chip (last 1m) on purpose, and change the touch screen.

4. When the mobile phone is turned on, the calibration screen will appear. It can be calibrated, but it cannot be completed.

Solution: Change the touch screen grid chip, write the full character library, install the cpu, solder or replace the touch ic, check whether there is an open circuit in the components around the touch ic, scratch the cover, and change the wiring of the flip machine.

5. If the touch of the mobile phone fails, it will be normal after disassembly, but it will fail after installation

Reason: The four sides of the touch screen are too tight

Solution: Remove the sealing strip, the root of the touch screen lead is broken and the connection is false, and the related components of the main board are soldered.
