Abstract:
A technique for reducing the kickback voltage error between two or more common voltage signal lines in a display device is provided. The kickback voltage error may be caused by driving a first and second common voltage at different levels. In one embodiment, a common voltage offset may be applied to the second common voltage such that the magnitude of the voltage kickback error is approximately equalized at the maximum and minimum pixel voltages for pixels coupled to the second common voltage. A data voltage offset, which may be determined based upon gray level data, may be applied to the data voltage supplied to the pixels coupled to the second common voltage. The foregoing technique may compensate for the kickback voltage error between the first and second common voltage lines, thereby reducing visual artifacts and improving color accuracy of the display.
