Predictive gamma algorithm for multiple display refresh rates

A system comprising:

• one or more processors;
• and
• data storage, wherein the data storage has stored thereon computer-executable instructions that, when executed by the one or more processors, cause the system to carry out operations comprising:
• measuring, from a device having a display panel configured to operate at a first refresh rate or a second refresh rate, a difference in color of the display panel between the first refresh rate and the second refresh rate for an input gray level;
• applying, based on the at least one measured difference, a value offset to a default gamma value used by the device for the input gray level when the display panel is operating at the second refresh rate, thereby generating a new gamma value, wherein the display panel has a plurality of color channels, wherein the default gamma value comprises respective register values for the plurality of color channels, and wherein the value offset comprises an offset to at least one of the register values of the default gamma value;
• and
• providing instructions to the device to override the default gamma value for the input gray level with the new gamma value when the display panel is operating at the second refresh rate.

A device comprising:

• a display panel configured to operate at a first refresh rate or a second refresh rate;
• and
• one or more processors configured to:
• receive a measured difference in color of the display panel between the first refresh rate and the second refresh rate for an input gray level;
• apply, based on the at least one measured difference, a value offset to a default gamma value used by the device for the input gray level when the display panel is operating at the second refresh rate, thereby generating a new gamma value;
• and
• store the new gamma value, wherein subsequent to the storing, the device is configured to override the default gamma value for the input gray level with the new gamma value when the display panel is operating at the second refresh rate, and
• wherein the display panel has a plurality of color channels, wherein the default gamma value comprises respective register values for the plurality of color channels, and wherein the value offset comprises an offset to at least one of the register values of the default gamma value.
