This study aimed to investigate the relative relationship between the components of LCD module. To find the best combination of relative components in the limited space and to achieve the optimal design of structural strength. To find the impact of structural strength in three main directions of LCD module. The first direction is to study the different thickness of glass and LGP combination in the same total thickness of the module. The second direction is to consider the gap between the glass, LGP and frame. The third direction is to consider the hardness of tape that bonding the upper and lower glass. The simulation results show that reducing the thickness of the glass and increase the thickness of LGP can make significant improvements in module strength in the same total thickness of the LCD module.
