不同偏压比对STN-LCD显示特性的影响

Influence of Different Bias Ratio on the Display Characteristics of the STN LCD

讨论了模块驱动 LCD条件中的偏压比的变化对 STN- LCD显示特性的影响。理论计算得出 ,相同占空比不同偏压比 Voff不同且对陡度要求不同 ,使得 STN- LCD工作范围不同 ,VOP偏离。最后得出结论 。

The paper discussed the influences of different bias ratio on the display chracteristics of the STN LCD driven by liquid crystal module (LCM). It has been calculated that, the different bias ratio in the same duty has different V th which requires different abruptness in LCD operation, As a result, the optimum operating voltage ( V op ) of the STN LCD is different. Best display effect can be achieved in the optimum bias ratio.
