AI Technical Summary
Technical Problem
In existing LED backlight modules, the light emission angle of the light source is small, the display effect is poor, and increasing the number of light-emitting diodes to reduce the spacing will lead to increased costs.
Method used
The system employs a combination structure of substrate, light guide layer, and light guide sheet. The light emission angle of the light source is adjusted through reflection and multiple reflections by the light guide sheet, thereby reducing the amount of light source used.
Benefits of technology
It improves the uniformity and brightness of the display effect and reduces manufacturing costs.
