Claim One:
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 using at least one of a voltage sensor, a current sensor, and a photo sensor; creating a stress pattern for said array, based on the extracted pixel parameter using a controller; stressing said pixels in accordance with said stress pattern using a current supply connected to the controller and the array of pixels; extracting said pixel parameter from the stressed pixels using at least one of the voltage sensor, the current sensor, and the photo sensor; in response to determining the pixel parameter extracted from the stressed pixels is not within a preselected range, using the controller for: a) creating an additional stress pattern for said array, based on the pixel parameter extracted from the stressed pixels; b) stressing said pixels in accordance with said additional stress pattern using the current supply; c) extracting said pixel parameter from the stressed pixels using at least one of the voltage sensor, the current sensor, and the photo sensor; d) determining when the pixel parameter extracted from the stressed pixels is within said preselected range; and e) until the pixel parameter extracted from the stressed pixels is within said preselected range repeat steps a), b), c), d) and e); and in response to the pixel parameter being within said preselected range returning said array of pixels to normal operation.
