How to brighten the 18 backlight lights?

1. First, include at least one brightness test point in the backlight module; in the direction perpendicular to the plane of the base plate.

2. Secondly, a thermoluminescent layer is included between the optical film layer and the bottom plate. The thermoluminescent layer emits light after absorbing heat to increase the brightness of the backlight module.
