AI Technical Summary
Backlight modules are prone to leakage and black screen issues during reliability tests, failing to meet the stringent requirements of automotive displays.
The assembly sequence of the backlight module is changed. The limiting component is fixed on the side plate of the back panel. The light-emitting side of the light guide plate is installed first, and then the light-incoming side is installed. A chamfer is set at the bottom of the light-incoming side of the light guide plate to avoid the circuit board and prevent scratching the circuit board.
This effectively avoids white spot defects and leakage, improves the reliability of the backlight module, meets the experimental requirements of automotive displays, and reduces the assembly defect rate.
