Systems and methods for reducing or eliminating mura artifact using image feedback

A system for programming a display panel comprising:

• a camera configured to capture images of an active area of the display panel substantially in real time;
• and
• a processor configured to:
• receive the images;
• cause the display panel to be programmed to a first gray level;
• cause an operating parameter of the display to be adjusted, wherein the operating parameter is configured to affect the mura artifact, such that the mura artifact is substantially reduced or eliminated at the first gray level in the images, wherein the operating parameter comprises a gate clock fall time, a gate clock overlap, a source output parking voltage, a resistance of at least one of a plurality of common voltage layers (VCOMs) of the electronic display, or any combination thereof;
• program the display panel to a second gray level at the operating parameter;
• and
• verify that the mura artifact is within a specified range in the images.

A method comprising:

• setting an electronic display to a first gray level;
• capturing images of the electronic display at a dynamic range sufficient to enable a mura artifact to be identified;
• adjusting an operating parameter of the electronic device until the mura artifact is substantially unidentifiable in the images at a first operating parameter value, wherein the operating parameter comprises a gate clock fall time, a gate clock overlap, a source output parking voltage, a resistance of at least one of a plurality of common voltage layers (VCOMs) of the electronic display, or any combination thereof;
• setting the electronic display to a second gray level;
• adjusting the operating parameter of the electronic device until the mura artifact is substantially unidentifiable in the images at a second operating parameter value;
• determining a final operating parameter value based at least in part on the first operating parameter value and the second operating parameter value;
• and
• storing the final operating parameter in storage associated with controlling the electronic display.

One or more articles of manufacture comprising:

• one or more tangible, non-transitory machine-readable media comprising processor-executable instructions to:
• cause pixels of an electronic display to be programmed to a first gray level;
• receive from a camera images of the electronic display showing a mura artifact substantially in real time;
• cause an operating parameter of the electronic display to be changed in discrete increments until the mura artifact is substantially indistinguishable at the first gray level in the images;
• cause pixels of an electronic display to be programmed to a second gray level;
• cause an operating parameter of the electronic display to be changed in discrete increments until the mura artifact is within a specified range;
• and
• causing the operating parameter to be stored in the electronic display, wherein the operating parameter comprises a gate clock fall time, a gate clock overlap, a source output parking voltage, a resistance of at least one of a plurality of common voltage layers (VCOMs) of the electronic display, or any combination thereof.
