1. A method of equalizing the pixels in an array of pixels that include semiconductor devices that age differently under different ambient and stress conditions, said method comprising extracting at least one pixel parameter from said array; creating a stress pattern for said array, based on the extracted pixel parameter; stressing said pixels in accordance with said stress pattern; extracting said pixel parameter from the stressed pixels; determining whether the pixel parameter extracted from the stressed pixels is within a preselected range and, when the answer is negative: creating a second stress pattern for said array, based on the pixel parameter extracted from the stressed pixels; stressing said pixels in accordance with said second stress pattern; extracting said pixel parameter from the stressed pixels; and determining whether the pixel parameter extracted from the stressed pixels is within said preselected range.
