System and method for compensation of non-uniformities in light emitting device displays

A method of adjusting the operating conditions for pixels in an OLED display to compensate for non-uniformity or aging of the display, said method comprising

• setting an initial operating condition 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, and
• if the determined number of pixels having compensation values larger than said predetermined threshold value is greater than a predetermined threshold number, adjusting the set initial operating condition value until said determined number of pixels is less than said predetermined threshold number.

A method of adjusting the operating conditions for pixels in an OLED display to compensate for non-uniformity or aging of the display, said method comprising

• setting initial values for peak luminance and an operating condition,
• calculating compensation values for the pixels in the display,
• determining 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, adjusting the set values for peak luminance and said operating condition until said determined number of pixels is less than said predetermined threshold number.

A display degradation compensation system for adjusting programming values for pixels in an OLED display to compensate for non-uniformity or aging of the display, said system comprising a controller programmed to

• set an initial peak luminance value,
• calculate compensation values for the pixels in the display,
• determine 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, reduce the set initial peak luminance value until said determined number of pixels is less than said predetermined threshold number.
