Abstract
A method for display flicker mitigation includes, at an ambient light sensor (ALS) of a touch-sensitive display device, detecting a display flicker condition affecting a touch-sensitive display of the touch-sensitive display device. One or more flicker mitigation operations are applied to alleviate the display flicker condition based at least in part on one or more flicker mitigation parameters.
Claims20
A method for display flicker mitigation, the method comprising:
- at an ambient light sensor (ALS) of a touch-sensitive display device, detecting a display flicker condition affecting a touch-sensitive display of the touch-sensitive display device as fluctuations in display light intensity emitted by the touch-sensitive display device;
- and
- responsive to detecting the fluctuations in display light intensity, applying one or more flicker mitigation operations to alleviate the display flicker condition based at least in part on one or more flicker mitigation parameters.
A touch-sensitive display device, comprising:
- a touch-sensitive display;
- an ambient light sensor (ALS);
- and
- a controller configured to:
- detect a display flicker condition affecting the touch-sensitive display via the ALS as fluctuations in display light intensity emitted by the touch-sensitive display device;
- and
- responsive to detecting the fluctuations in display light intensity, apply one or more flicker mitigation operations to alleviate the display flicker condition based at least in part on one or more flicker mitigation parameters.
4 more elements
A method for display flicker mitigation, the method comprising:
- at an ambient light sensor (ALS) of a touch-sensitive display device, detecting a display flicker condition affecting a touch-sensitive display of the touch-sensitive display device as fluctuations in display light intensity emitted by the touch-sensitive display device, wherein the ALS is disposed beneath the touch-sensitive display, and wherein the display flicker condition is caused by transmission of a data uplink signal to an active stylus;
- and
- responsive to detecting the fluctuations in display light intensity, applying one or more flicker mitigation operations to alleviate the display flicker condition based at least in part on one or more flicker mitigation parameters, including a detected position of the active stylus relative to the touch-sensitive display.
