Why is the car's central control screen aging and turning white?

This situation indicates that the screen has reached the end of its service life, and it is recommended to replace it. Introduction: The central control refers to the central control system. The central control system is a device that centrally manages and controls various equipment such as sound, light, and electricity. Application: It is widely used in multimedia classrooms, multi-functional conference halls, command and control centers, smart homes, etc. Users can use button control panels, computer displays, touch screens, and wireless remote controls, among other devices. Principle: Through a computer and central control system software, it sends serial port commands to control projectors, display stands, DVD players, video recorders, tape decks, amplifiers, microphones, computers, laptops, electric screens, electric curtains, lighting, and other equipment.
I've encountered this before! When the center console screen turns whitish and foggy after prolonged use, it's most likely due to LCD panel aging. Especially after summer sun exposure when car interior temperatures soar, this accelerates LCD deterioration. Sometimes you'll notice the whitening starts from screen edges before gradually spreading to the center. Don't tough it out - severely whitened screens make navigation difficult. While touch functionality still works, replace it promptly. Aftermarket screens nowadays offer great value for money.
Based on repair experience, there are three main situations for a whitening central control screen: the most common is aging backlight tubes, causing uneven lighting and localized whitening; secondly, liquid crystal layer leakage can produce cloud-like white spots; and thirdly, poor contact in the wiring can cause the entire screen to suddenly turn white. It is recommended to first turn off and restart the vehicle to see if the issue resolves. If the screen returns to normal after restarting, it is likely a wiring problem. Vehicles frequently used for long-distance travel should pay special attention to heat dissipation, as high temperatures are a major killer of screens.
