Abstract
A liquid crystal display with uniform feed-through voltage includes a plurality of data lines for receiving a plurality of data signals respectively, a plurality of gate lines for receiving a plurality of gate signals respectively, a plurality of common lines for receiving a common voltage, a plurality of storage units, a plurality of first switches, and a plurality of second switches. Each storage unit includes a first liquid crystal capacitor and a second liquid crystal capacitor coupled to a corresponding common line. Each first switch is coupled to a corresponding data line, a corresponding gate line, and a corresponding first liquid crystal capacitor. Each second switch is coupled to a corresponding gate line, a corresponding first switch, and a corresponding second liquid crystal capacitor. The capacitance of the gate-source capacitor of each first switch is greater than the capacitance of the gate-source capacitor of each second switch.
