基础液晶显示器驱动原理 Passive Bias Generation LCD load is capacitive, the current during element charging and discharging distorts the waveform. Generally, the value of resistor R is 1 k to 10 k. Lower resistor values reduce distortion but increase power dissipation. Larger LCD panels exhibit greater capacitance. Connecting a capacitor in parallel to the resistors can reduce waveform distortion. Larger capacitor values generate a voltage level shift and reduce the operating margin. 2011/4/18 Write by Hersing Yang 41 Active Bias Generation 2011/4/18 Write by Hersing Yang 42
