What Causes the In-Car Display Touch Screen to Stop Responding?
3 Answers
Reasons why the in-car display touch screen stops responding: 1. The car navigation touch screen is extremely sensitive to static electricity: It can easily damage the capacitive screen. Although the glass surface of the car navigation touch screen has some anti-static treatment, it does not mean it can withstand the static electricity from the human body in winter. 2. The car navigation touch screen is sensitive to conductive substances like oil and sweat: These can form a conductive layer on the screen, causing screen drift. Wash your hands and dry them before use. 3. The car navigation touch screen is sensitive to 'high' temperatures: The 'high' temperature here does not mean using fire, but temperatures around 40 degrees Celsius can cause capacitive screen drift. Prolonged exposure to such temperatures can permanently damage the capacitive screen. Avoid direct sunlight and prolonged use under high-temperature conditions.
When the touch screen on my car's display malfunctions, I find this issue quite common. Usually, it's because the screen surface is dirty or has oil stains, affecting the sensing function. I've tried it myself several times—gently wiping it with a damp cloth often restores functionality, which is very convenient. Additionally, if the weather is too cold or too hot, the screen response may become sluggish; unstable battery voltage can also cause issues. A more complex reason could be software lag, such as an improperly installed system update or a frozen background app. The solution is simple: restart the infotainment system, turn off the car for a few minutes, and then start it again—this usually fixes the problem. For daily maintenance, remember to avoid spilling drinks or applying sunscreen near the screen to prevent corrosion of the circuits. Also, prolonged vibrations may loosen connections, which can be resolved by getting it checked.
Once, while I was driving with navigation on, the display suddenly became unresponsive, which was quite annoying. Later, when I took it to the repair shop, I found out it was because the software version was too old and needed an upgrade to match the new car system. Some people have also encountered issues like water damage or short circuits due to moisture, especially on rainy days when opening the rear window causes heavy fogging. It's good practice to clean the screen regularly to prevent accidental touches. If it's a hardware issue, like aging wiring or panel damage, you'll need a professional technician to check it. Personally, I think prevention is key—regular maintenance to check the battery status and avoid leaving the car parked for too long to prevent battery drain. Nowadays, many new cars come with touchscreens, and system bugs are common, but timely firmware updates can prevent malfunctions from affecting safety.
