Overshoot driving technique for display panel with multiple regions with different pixel layouts

Abstract:

A display driver includes image processing circuitry and drive circuitry. The image processing circuitry is configured to receive first subpixel data for a first scan line of a display panel. The display panel includes a first region with a first pixel layout and a second region with a second pixel layout different from the first pixel layout. The image processing circuitry is further configured to determine an overshoot amount based, at least in part, on the first subpixel data and region indication data and generate resulting voltage data using the overshoot amount. The region indication data indicates whether the resulting voltage data is for the first region or for the second region. The drive circuitry is configured to drive the display panel based, at least in part, on the resulting voltage data.
