AI Technical Summary
Technical Problem
Existing light guide designs that use multiple lamps as light sources suffer from uneven light distribution, large product size, high cost, and high power consumption in small electronic products, making it difficult to meet the requirements of miniaturization and long battery life.
Method used
The design combines a backlight panel, a first diffuse reflection structure, and a reflector. By using diffuse and reflective structures, light is diffused to the center and direction of the backlight panel, reducing the number of light sources and improving brightness and uniformity.
Benefits of technology
It achieves uniform light emission, high brightness, and low cost, reducing component size and power consumption, which helps in product miniaturization and long battery life.
