Abstract：This paper proposes a fuzzy strategy for the generation of the dot pattern, in order to effectively integrate the dot pattern scheme into the subsequent optical design phase for the optimization of the dot distribution. The fuzzy dot-generation strategy is based on the fuzzy logic and rules, which are closely related to the physical luminance properties. Furthermore, the optical performance of the backlight system is presented. The validity of the proposed solution is confirmed through a series of simulations. The results reveal that the proposed method can achieve an even luminance condition by establishing a dot pattern. Compared to conventional methods, the fuzzy dot-generation strategy has two advantages. It effectively integrates the dot generation scheme into the subsequent optical design phase to make the dot pattern more efficient and easy to control. Moreover, luminous intensity variations across the surface are typically minor.
