Micro-OLED Sub-Pixel Uniformity Compensation Architecture for Foveated Displays

A method comprising:

• receiving, via processing circuitry, gray level data and operating characteristics of a display panel;
• converting, via the processing circuitry, the gray level data to voltage data;
• determining, via the processing circuitry, a compensation based on a global voltage compensation value and a local voltage compensation value;
• generating, via the processing circuitry, compensated image data by applying the compensation to the gray level data;
• and
• converting, via the processing circuitry, the compensated image data to compensated gray level data by compressing a voltage domain range of the compensated image data based on the operating characteristics of the display panel.

Processing circuitry, comprising:

• first conversion circuitry configured to convert source image data corresponding to a display pixel of a plurality of display pixels of an electronic display from gray level data of the source image data to voltage data;
• non-uniformity correction circuitry configured to generate compensated voltage data based on the voltage data, a global compensation map, and a local compensation map;
• and
• second conversion circuitry configured to convert the compensated voltage data to digital code corresponding to the display pixel by:
• receiving an indication of operating characteristics of a display panel;
• compressing a voltage domain range of the compensated voltage data based on the operating characteristics of the display panel;
• and
• converting the compensated voltage data to the digital code.
