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.

Abstract: This application relates to systems, methods, and apparatus for compensating voltage for pixels of a display panel based on the location of the pixels within the display panel. An amount of voltage compensation is assigned to each pixel or a group of pixels within the display panel in accordance with a calibration of the display panel. During operation of the display panel, pixel data is generated for a location of the display panel, and the pixel data is modified according to the amount of voltage compensation corresponding to the location. By modifying the pixel data in this way, spatial variations in voltage across the display panel can be mitigated in order to reduce the occurrence of certain display artifacts at the display panel.
