Producing consistent gamma in organic light-emitting diode display devices
An information handling system determines an average picture level percentage of a previous frame and determines a brightness level of a current frame based on the average picture level percentage of the previous frame. The information handling system also determines a panel gray level based on the brightness level of the current frame.
1 . A method comprising:
determining, by a processor of an information handling system, an average picture level percentage of a previous frame;
determining a brightness level of a current frame based on the average picture level percentage of the previous frame; and
determining a panel gray level based on the brightness level of the current frame.
2 . The method of claim 1 , further comprising predicting a panel gamma curve based on the panel gray level.
3 . The method of claim 1 , further comprising adjusting an initial input gray level of the current frame.
4 . The method of claim 1 , further comprising utilizing the panel gray level when displaying an image.
5 . The method of claim 1 , wherein the determining of the panel gray level is further based on an input gray level.
6 . The method of claim 1 , wherein the determining of the panel gray level is further based on a peak brightness level associated with a display mode of a display device.
7 . The method of claim 1 , further comprising determining a scaler gamma curve.
