Abstract:
A display device may include a source line that provides a data line signal to a pixel of the display device, a gate line that provides a gate signal to a switches associated with the pixel, and a voltage gate line disposed parallel to the source line and coupled to the gate line at a cross point node. The display device may also include a driver circuit that receives a pixel value to provide to the pixel, determines a compensation amount for the pixel value based on an expected kickback voltage present on the pixel due to a coupling effect between the source line and the voltage gate line, generates a compensated data line signal based on the compensation value and the pixel value, and provides the compensated data line signal to the pixel via the source line.
