Patent ID: 7612787

Claim:
A process for operating a wear-afflicted display having defined pixels, comprising: assigning each pixel a memory address in a memory element to record an operating time of each pixel, the pixel being integrated over the operating time and operating intensity to determine a pixel wear value (R int , G int , B int ); storing the pixel wear value for each pixel in the form of a non-volatile stored pixel wear value (R vn , G vn , B vn ) in a non-volatile memory for each of the three basic colors including red, green, and blue; obtaining the non-volatile stored pixel wear value (R vn , G vn , B vn ) as a sum of the most significant bits integrated over the operating time of the pixel of a pixel wear value (R vf , G vf , B vf ) that is volatile stored in a volatile memory, wherein the less significant bits of the volatile stored pixel wear value (R vf , G vf , B vf ) are retained unchanged in the volatile memory and the most significant bits of the volatile stored pixel wear values (R vf , G vf , B vf ) are transferred to the non-volatile stored pixel wear values (R vn , G vn , B vn ).
