What is the reason for half of the car display screen's touch function failing?
2 Answers
The main reason for touch screen failure is malfunction or damage. The specific reasons are introduced as follows: Damage: It may be due to touch screen damage, and professional repair at a 4S shop is recommended. Malfunction: It may be due to a malfunction, try resetting it. The reset button is generally located on the screen or main unit, either as a small round hole or a small button. You can use a paperclip or toothpick to press the DVD's RST hole (reset button) to restore the device to its initial state. Extended information: Car navigation system: The onboard GPS navigation system receives data from at least three of the 24 GPS satellites orbiting the Earth through its built-in GPS antenna. Combined with the electronic map stored in the onboard navigator, it matches the position coordinates determined by the GPS satellite signals to determine the car's precise location on the electronic map, which is commonly referred to as the positioning function.
Last time I encountered a similar issue, I found that half of the car's touchscreen was unresponsive, usually due to localized damage to the internal touch layer, such as scratches from hard objects or aging fractures caused by high temperatures. It could also be a loose connection in the wiring harness, where rough road conditions might cause the connector to disconnect, interrupting signals in certain areas. Software glitches can also cause trouble, like functional errors after a system update, rendering half the screen useless. Dust buildup or accidental spills can also affect touch sensitivity. I find this quite annoying because it can lead to errors when using navigation or adjusting the AC, increasing driving risks. So, don't attempt DIY fixes—first, clean the screen with a soft cloth and restart the system. If that doesn't work, take it to a professional shop to check the hardware and wiring.
