SYSTEM AND METHOD FOR COMPENSATION OF NON-UNIFORMITIES IN LIGHT EMITTING DEVICE DISPLAYS
First Claim
1. A method of adjusting programming values for pixels in an OLED display to compensate for non-uniformity or aging of the display, said method comprisingsetting an initial peak luminance value,calculating compensation values for the pixels in the display,determining the number of pixels having compensation values larger than a predetermined threshold compensation value, andif the determined number of pixels having compensation values larger than said predetermined threshold value is greater than a predetermined threshold number, reducing the set initial peak luminance value until said determined number of pixels is less than said predetermined threshold number.

Abstract
A display degradation compensation system and method for adjusting the operating conditions for pixels in an OLED display to compensate for non-uniformity or aging of the display. The system or method sets an initial value for at least one of peak luminance and an operating condition, calculates compensation values for the pixels in the display, determines the number of pixels having compensation values larger than a predetermined threshold compensation value, and if the determined number of pixels having compensation values larger than said predetermined threshold value is greater than a predetermined threshold number, adjusts the set value until said determined number of pixels is less than said predetermined threshold number.
