P‐79: Light Leakage Improvement of LCD Module by Numerical Analysis

In this paper, we discuss the light leakage issue of LCD panel occurred due to sharp temperature gradient and non‐uniform stress distribution. By using numerical analysis and experiments, the relationship between light leakage and temperature gradient has been discovered. Thermal and stress simulations are applied in the analysis of light leakage phenomenon. Besides, we use simulation tools to predict the effectiveness of solutions for reducing the temperature gradient and stress distribution of LCD glass substrates. Finally, light leakage has been improved by using the rear frame with high thermal conductivity to reduce the temperature gradient and stress of the LCD panel.
