Once the all-glass module known as "0 light leakage" was released, I paid attention to it. In my opinion, the chief culprit of screen light leakage is actually the acrylic light guide plate in the display.
People who know about acrylic materials will know that acrylic is a kind of plastic, similar to the material in car headlights. It is very easy to yellow and break after long-term heating, not to mention deformation.
When the light guide plate in the display is deformed, it will squeeze the screen panel and backplane, which will eventually lead to the overall deformation of the screen, resulting in a gap between the screen and the frame, which will eventually lead to light leakage on the screen.
The biggest highlight of this all-glass module technology is that the light guide plate in the display is replaced by Corning glass light guide plate, which greatly prolongs the life of the screen and makes it not deform and yellow after long-term use. It is the perfect solution for screen light leakage at present.
