Display panel adjustment from temperature prediction
Systems, methods, and devices for adjusting image display on an electronic display by predicting a temperature change of the electronic display due to heat-producing components near the display or due to changes in content. An electronic device may include an electronic display and processing circuitry. The electronic display may include pixels with behaviors that vary with temperature. As such, the processing circuitry may generate image data to send to the electronic display and adjust the image data or vary an operation of the electronic display based at least in part on a predicted temperature effect on at least part of the active area of the electronic display. The processing circuitry may determine the predicted temperature effect at least in part due to a first heat producing component or changes in content of the image data.
1. A method comprising:
displaying frames of image data on an electronic display at a first frame rate; and
in response to predicting that a change in content between two frames of the image data would result in a temperature change of the electronic display that would cause a visual artifact on the electronic display, causing the electronic display to refresh sooner than the first frame rate to prevent an appearance of the visual artifact on the electronic display.
2. The method of claim 1 , wherein the change in content comprises an increase in brightness that causes the electronic display to increase in temperature over time.
3. The method of claim 1 , wherein the change in content comprises a decrease in brightness that causes the electronic display to decrease in temperature over time.
4. The method of claim 1 , wherein the change in content between the two frames of image data comprises a change in content of a first subset of the frames of image data, wherein the first subset is less than a whole frame.
5. The method of claim 4 , wherein the first subset is more than a single pixel.
6. The method of claim 1 , comprising predicting a rate of temperature change based on the change in content between the two frames of image data and predicting when the rate of temperature change would cause enough temperature change over time to result in the visual artifact.
7. The method of claim 6 , comprising accumulating a total temperature change since a most recent refresh based on the predicted rate of temperature change and predicting when the rate of temperature change would cause enough temperature change over time to result in the visual artifact when the accumulated total temperature change exceeds a first threshold of temperature increase or falls beneath a second threshold of temperature decrease.
8. The method of claim 1 , wherein the content comprises images, videos, text, and any combination thereof.
9. An electronic device comprising:
an electronic display comprising an active area, wherein the active area comprises pixels configured to display image frames based on corresponding image data at a first frame rate; and
processing circuitry communicatively coupled to the electronic display, wherein the processing circuitry is configured to:
predict whether content of the image data would produce a temperature change of the electronic display within a time period of the first frame rate that would result in a visual artifact on the electronic display; and
in response to predicting that content of the image data would produce the temperature change of the electronic display within the time period of the first frame rate that would result in the visual artifact, cause the electronic display to refresh earlier than the first frame rate to prevent an appearance of the visual artifact on the electronic display.
10. The device of claim 9 , wherein the content comprises an area of relatively high brightness to cause the electronic display to increase in temperature within the time period of the first frame rate.
11. The device of claim 9 , wherein the content comprises an area of relatively low brightness to cause the electronic display to decrease in temperature within the time period of the first frame rate.
12. The device of claim 9 , wherein the temperature change due to the content comprises a temperature change of the electronic display due to a change in content between image frames.
13. The device of claim 12 , wherein the temperature change of the electronic display due to the change in content comprises an increase in brightness that would cause the electronic display to increase in temperature within the time period of the first frame rate.
14. The device of claim 12 , wherein the temperature change of the electronic display due to the change in content comprises a decrease in brightness that would cause the electronic display to decrease in temperature within the time period of the first frame rate.
15. The device of claim 12 , wherein the change in content comprises a change in content of less than an entire image frame.
16. The device of claim 15 , wherein the change in content less than the entire image frame comprises a change in more than a single pixel.
17. The device of claim 9 , wherein the processing circuitry is configured to:
predict a rate of temperature change of the electronic display based on the content; and
predict a point in time when the rate of temperature change would cause enough temperature change over time to result in the visual artifact.
18. The device of claim 17 , wherein the processing circuitry is configured to:
accumulate a total temperature change of the electronic display since a most recent refresh based on the predicted rate of temperature change; and
predict the point in time when the rate of temperature change would cause enough temperature change over time to result in the visual artifact when the accumulated total temperature change exceeds a first threshold of temperature increase or falls beneath a second threshold of temperature decrease.
19. An article of manufacture comprising one or more tangible, non-transitory, machine-readable media comprising instructions to:
cause frames of image data to be displayed on an electronic display at a first frame rate; and
in response to determining that image data content would produce a temperature change of the electronic display within a time period of the first frame rate that would result in a visual artifact, cause the electronic display to refresh earlier than the first frame rate to prevent the visual artifact from appearing on the electronic display.
20. The article of manufacture of claim 19 , wherein the image data content comprises a change in content between two frames of image data that causes the electronic display to increase in temperature over time.
21. The article of manufacture of claim 19 , wherein the image data content comprises a change in content between two frames of image data that causes the electronic display to decrease in temperature over time.
