Abstract

A method for operating an electronic display includes displaying image frames and receiving operational parameters of the electronic display based on illuminating a sense pixel of at least one row of pixels of the electronic display when displaying the image frames. A first set of pixels below the at least one row of pixels renders a portion of a first image frame and a second set of pixels above the at least one row of pixels renders a portion of a second image frame. The method also includes adjusting image display of a third image frame on the electronic display based on the operational parameters.

Claims (34)

1. An electronic device, comprising:

a display pipeline configured to receive image data to be displayed as a plurality of image frames from an image data source;

an electronic display configured to display the plurality of image frames, wherein the electronic display comprises:

a display panel comprising at least one pixel row; and

a display driver communicatively coupled to the display pipeline, wherein the display driver is configured to refresh the at least one pixel row by writing the image data to the at least one pixel row; and

a controller communicatively coupled to the display pipeline, wherein the controller is configured to:

perform a plurality of sensing operations at a frequency by illuminating a sense pixel of at least one row of pixels of a portion of the electronic display displaying the plurality of image frames;

adjust image display on the display panel based at least in part performing the plurality of sensing operations; and

adjust the frequency of the plurality of sensing operations based at least in part on sensor data provided by the plurality of sensing operations.

2. The electronic device of claim 1 , wherein a first set of pixels below the at least one row of pixels renders a portion of a first image frame of the plurality of image frames and a second set of pixels above the at least one row of pixels renders a portion of a second image frame of the plurality of image frames.

3. The electronic device of claim 1 , comprising an ambient light sensor, a touch sensor, or a combination thereof, wherein the sensor data comprises ambient light sensor data provided by the ambient light sensor, touch sensor data provided by the touch sensor, or a combination thereof.

4. The electronic device of claim 1 , wherein the controller is configured to adjust the frequency of the plurality of sensing operations based at least in part on a difference between first sensor data resulting from a first sensing operation of the plurality of sensing operations associated with a first image frame and second sensor data resulting from a second sensing operation of the plurality of sensing operations associated with a second image frame.

5. The electronic device of claim 4 , wherein the controller is configured to adjust the frequency of the plurality of sensing operations by increasing the frequency of the plurality of sensing operations in response to determining that the difference between the first sensor data and the second sensor data is greater than a threshold value.

6. The electronic device of claim 5 , wherein the controller is configured to maintain the frequency of the plurality of sensing operations in response to determining that the frequency is greater or equal to a maximum threshold frequency.

7. The electronic device of claim 4 , wherein the controller is configured to adjust the frequency of the plurality of sensing operations by decreasing the frequency of the plurality of sensing operations in response to determining that the difference between the first sensor data and the second sensor data is less than a threshold value.

8. The electronic device of claim 7 , wherein the controller is configured to maintain the frequency of the plurality of sensing operations in response to determining that the frequency is less than or equal to a minimum threshold frequency.

9. The electronic device of claim 4 , wherein the first sensor data and the second sensor data each comprises ambient temperature, humidity, brightness, or any combination thereof.

10. A method for operating an electronic display, comprising:

displaying a plurality of image frames in a sensing operation set period of time;

performing a set of sensing operations in the sensing operation set period of time by illuminating a sense pixel of at least one row of pixels of a first portion of the electronic display displaying a first image frame of the plurality of image frames; and

adjusting image display on the electronic display based at least in part on performing the set of sensing operations.

11. The method of claim 10 , wherein display the plurality of image frames comprises displaying a second image frame of the plurality of image frames and not performing a sensing operation by illuminating a second portion of the electronic display displaying the second image frame.

12. The method of claim 11 , wherein the second image frame is displayed immediately after displaying the first image frame.

13. The method of claim 11 , comprising receiving sensor data when displaying the second image frame, wherein the sensor data comprises ambient light sensor data provided by an ambient light sensor of the electronic display, touch sensor data provided by a touch sensor of the electronic display, or a combination thereof.

14. The method of claim 13 , comprising adjusting second image display on the electronic display based at least in part on receiving the sensor data.

15. The method of claim 10 , wherein a first set of pixels below the at least one row of pixels renders a portion of the first image frame and a second set of pixels above the at least one row of pixels renders a portion of a second image frame.

16. A tangible, non-transitory, computer-readable medium that stores instructions executable by one or more processors in an electronic device, wherein the instructions comprise instructions to:

display a plurality of image frames;

receive operational parameters of an electronic display of the electronic device based at least in part on illuminating a sense pixel of at least one row of pixels of the electronic display when displaying the plurality of image frames, wherein a first set of pixels below the at least one row of pixels renders a portion of a first image frame of the plurality of image frames and a second set of pixels above the at least one row of pixels renders a portion of a second image frame of the plurality of image frames; and

adjust image display of a third image frame the plurality of image frames on the electronic display based at least in part on the operational parameters.

17. The computer-readable medium of claim 16 , wherein the instructions comprise instructions to illuminate only one row of pixels of the electronic display when displaying each image frame of the plurality of image frames.

18. The computer-readable medium of claim 16 , wherein the instructions comprise instructions to not illuminate the at least one row of pixels of the electronic display when displaying the second image frame.

19. The computer-readable medium of claim 16 , comprising receiving sensor data when displaying the second image frame, wherein the sensor data comprises ambient light sensor data provided by an ambient light sensor of the electronic display, touch sensor data provided by a touch sensor of the electronic display, or a combination thereof.

20. The computer-readable medium of claim 19 , comprising adjusting the image display of the third image frame based at least in part on receiving the sensor data.
