Abstract

Claims (29)

1. A device comprising:

a touch sensor comprising micro-features comprising lines of conductive material, the lines of conductive material comprising a mesh;

a display comprising a plurality of pixels, the touch sensor overlaid on the display; and

a computer-readable non-transitory storage medium coupled to the display and embodying logic that is configured when executed to:

determine output modifications to apply to the pixels based on a modification map, the modification map providing output-modification values for the pixels to mitigate optical occlusion of pixels optically occluded by micro-features of the touch sensor relative to other pixels not optically occluded by micro-features of the touch sensor; and

apply the output modifications to pixels to mitigate their optical occlusion relative to other pixels not optically occluded by micro-features of the touch sensor.

2. The device of claim 1 , wherein the logic is further configured to increase an output intensity of the optically occluded pixels relative to an output intensity of the other pixels not optically occluded.

3. The device of claim 1 , wherein is the logic further configured to decrease an output intensity of the other pixels not optically occluded relative to an output intensity of the optically occluded pixels.

4. The device of claim 1 , wherein the modification map provides output-modification values that substantially randomizes an output intensity of the pixels, the randomization being proportional to a density of micro-features resulting in optical white noise being applied an output of the display.

5. The device of claim 1 , wherein the logic is further configured to apply the modification map to an unmodified display-data file.

6. The device of claim 5 , wherein the logic is further configure to perform a logical AND or logical OR operation between the modification map and the unmodified display-data file.

7. A method, executed by logic embodied in a computer-readable non-transitory medium, comprising:

determining output modifications to apply to pixels of a display based on a modification map for pixels of the display, the modification map providing output-modification values for the pixels to mitigate optical occlusion of pixels of the display optically occluded by micro-features of a touch sensor overlying the display relative to other pixels of the display not optically occluded by micro-features of the touch sensor; and

applying the output modifications to pixels of the display to mitigate their optical occlusion relative to other pixels of the display not optically occluded by micro-features of the touch sensor.

8. The method of claim 7 , wherein micro-features comprising lines of conductive material comprising a mesh.

9. The method of claim 7 , wherein providing output-modification values comprising increasing an output intensity of the optically occluded pixels relative to an output intensity of the other pixels not optically occluded.

10. The method of claim 7 , wherein providing output-modification values comprising decreasing an output intensity of the other pixels not optically occluded relative to an output intensity of the optically occluded pixels.

11. The method of claim 7 , wherein the modification map provides output-modification values that substantially randomizes an output intensity of the pixels, the randomization being proportional to a density of micro-features resulting in optical white noise being applied an output of the display.

12. The method of claim 7 , wherein applying the output modifications comprising applying the modification map to an unmodified display-data file.

13. The method of claim 12 , wherein applying the modification map comprising performing a logical AND or logical OR operation between the modification map and the unmodified display-data file.

14. A computer-readable non-transitory storage medium embodying logic configured when executed to:

determine output modifications to apply to pixels of a display based on a modification map for pixels of the display, the modification map providing output-modification values for the pixels to mitigate optical occlusion of pixels of the display optically occluded by micro-features of a touch sensor overlying the display relative to other pixels of the display not optically occluded by micro-features of the touch sensor; and

apply the output modifications to pixels of the display to mitigate their optical occlusion relative to other pixels of the display not optically occluded by micro-features of the touch sensor.

15. The medium of claim 14 , wherein micro-features comprising lines of conductive material comprising a mesh.

16. The medium of claim 14 , wherein the logic is further configured to increase an output intensity of the optically occluded pixels relative to an output intensity of the other pixels not optically occluded.

17. The medium of claim 14 , wherein is the logic further configured to decrease an output intensity of the other pixels not optically occluded relative to an output intensity of the optically occluded pixels.

18. The medium of claim 14 , wherein the modification map provides output-modification values that substantially randomizes an output intensity of the pixels, the randomization being proportional to a density of micro-features resulting in optical white noise being applied an output of the display.

19. The medium of claim 14 , wherein the logic is further configured to apply the modification map to an unmodified display-data file.

20. The medium of claim 19 , wherein the logic is further configured to perform a logical AND or logical OR operation between the modification map and the unmodified display-data file.
