Abstract
A liquid crystal display having pixel data self-retaining functionality includes a gate line for delivering a gate signal, a data line for delivering a data signal, a control unit for providing a first control signal and a second control signal, a data switch, a voltage-control inverter, a liquid crystal capacitor, and a pass transistor. The data switch is utilized for inputting the data signal to become a first data signal according to the gate signal. The voltage-control inverter is utilized for inverting the first data signal to generate a second data signal furnished to the liquid crystal capacitor according to the enable operation of the first control signal. The pass transistor is used for passing the second data signal to become the first data signal or for passing the first data signal to become the second data signal according to the second control signal.
