Optimizing the shape of the microstructure and the number of dots on the front light guide plate to reduce manufacturing energy consumption

The front light guide panel is situated in front of the liquid crystal display (LCD) layer. The light guide plate plays a crucial role in uniformly distributing the emitted light across the entire screen surface. This technology is particularly advantageous for e-book readers or in environments with limited illumination, as it provides front lighting that helps to alleviate eye fatigue. The objective of this study is to enhance the design of the dot microstructure of the light guide plate within the front light module while simultaneously reducing the number of dots. The optimization of the dot microstructure shape is conducted using a randomized algorithm, employing the root mean square as the target metric. This aims to improve the uniformity of light output from the front light module while decreasing the number of dots. The results of the research indicate that transforming the conventional crater shape, widely used in the industry, into a triangular dot microstructure could potentially reduce the number of dots from 1,694,459 to 746,125. This innovative approach has the capacity to streamline the manufacturing process, minimize costs, and decrease manufacturing energy consumption. Overall, the cost reduction is projected to reach as high as 44%.
