Abstract
A pixel circuit for a liquid crystal display panel includes a capacitor unit, a voltage-regulating mechanism, a first switching member, and a second switching member. The liquid crystal display panel includes a plurality of scan lines and data lines. The voltage-regulating mechanism is coupled to the first and second liquid crystal capacitors thereby enabling the first and second liquid crystal capacitors to be configured with different voltages when a voltage is applied to the capacitor unit. The first switching member is coupled to the capacitor unit, one of two corresponding scan lines, and one of two corresponding data lines. The second switching member is coupled to the second liquid crystal capacitor, the other of two corresponding scan lines.
