Patent ID: 7215333

Claim:
A method of controlling a driver circuit of an LCD device, wherein the driver circuit comprises a plurality of data drivers and at least two gate drivers, the data drivers are connected to data lines, the gate drivers are connected to gate lines, an overlapping area of a data line and a gate line defines a pixel of the LCD device, the data drivers applies driving voltages corresponding to a line of picture image onto a scan line of pixels through the data lines, and the gate drivers turn on the gate lines by asserting gate driving signals onto the gate lines so that the scan lines of pixels are displayed, comprising: selecting a first gate driver from the at least two gate drivers based on a selection rule, wherein the first gate driver sequentially turns on a pre-determined range of gate lines starting from a gate line A and, thereby, a part of a picture image is displayed on the LCD device; and selecting a second gate driver from the at least two gate drivers based on the selection rule, wherein the second gate driver simultaneously turns on the pre-determined range of gate lines starting from a gate line B that is separated from the gate line A by a pre-determined gap of gate lines and, thereby, a part of a special image whose corresponding driving voltages are of a specific target value.
