ADAPTIVE SPATIAL OFFSET CANCELLATION OF SOURCE DRIVER
A display panel subsystem adaptively employs one of three types of input offset voltage cancellation modes based on an analysis of gray level values of sub-pixels for each row un a frame of image data. The system selects a candidate row within a selected group of rows and applies a first chopper mode to each sub-pixel in the candidate row. Under a row-based mode, the system applies a second chopper mode to each sub-pixel included in a row having gray level values matching the candidate row. Under a per-column row-based mode, the system applies the row-based mode on a per-column basis. Under a sub-pixel-wise mode, for each column, the system changes a chopper mode applied to a sub-pixel in a subsequent row relative to the last state of the chopper mode in a row having the same gray level value as a corresponding sub-pixel in the subsequent row.
