Abstract
A display driver includes image processing circuitry and drive circuitry. The image processing circuitry is configured to determine a total current of a display panel and perform an IR-drop compensation using the total current and a first graylevel for a first subpixel of the display panel to determine a first voltage level for the first subpixel. The drive circuitry is configured to update the first subpixel based at least in part on the first voltage level.
Claims20
A display driver, comprising:
- image processing circuitry configured to:
- determine a total current of a display panel, and
- perform an IR-drop compensation using the total current and a first graylevel for a first subpixel of the display panel to determine a first voltage level for the first subpixel using gamma voltage data, gain data, and offset data, wherein the total current is used to determine the gain data and the offset data;
- and
- drive circuitry configured to update the first subpixel based at least in part on the first voltage level.
