Patent ID: 7002542

Claim:
An active matrix liquid crystal display apparatus, comprising: a pixel having a switching transistor, wherein the switching transistor includes a gate electrode, a source electrode, and a drain electrode that is connected to a pixel electrode; a data signal line connected to the source electrode; a gate signal line connected to the gate electrode; and a gate driver connected to the gate signal line, said gate driver including a first voltage source, a second voltage source, and a switch for selectively applying, in response to gate control signals, a reference potential, the first voltage, or the second voltage to the gate signal line, wherein the gate signal line is electrically connected to the gate electrode; a data driver connected to the data signal line, said data driver for selectively applying a data signal having a data signal voltage to the data signal line, wherein the data signal line is electrically connected to the source electrode; and a gate controller for selectively applying gate control signals to the gate driver; wherein the gate controller applies gate control signals that cause the gate driver to apply the first voltage to the gate signal line during the application of the data signal to the pixel electrode through the data signal line; wherein the gate controller applies gate control signals that cause the gate driver to apply the second voltage to the gate signal line after the application of the first signal voltage, but during the application of the data signal to the pixel electrode though the data signal line; wherein the gate controller applies gate control signals that cause the gate driver to apply the reference potential to the gate signal line after the application of the second signal voltage but during the application of the data signal to the pixel electrode through the data signal line; wherein the first voltage is greater than the data signal voltage and turns on the switching transistor; wherein the second voltage is near the data signal voltage; and wherein the reference voltage turns off the switching transistor.
