Correction for localized phenomena in an image array
First Claim
1. A method of compensating for localized phenomena in a display device including an array of pixels and a controller for adjusting data content signals for the array of pixels to compensate for aging of the pixels in the array, said method comprising;
- measuring a parameter of at least one of the pixels in the array, the at least one of the pixels being one of a subset of pixels of the pixels of the array affected by a localized phenomena, the parameter associated with the localized phenomena, wherein the localized phenomena does not affect the pixels in the array other than the subset of pixels;
determining the effect of the localized phenomena using the parameter;
measuring a characteristic associated with the aging of the pixels in the array for at least one of the pixels in the array;
adjusting the measured characteristic as a function of the measured parameter associated with the localized phenomena to reduce the effect of the localized phenomena;
calculating an adjusted aging compensation value based on the adjusted measured characteristic; and
applying the adjusted aging compensation value to a data content signal to at least one of the pixels in the subset of pixels affected by the localized phenomena.

Abstract
A method and system of compensating for localized phenomena in a display is disclosed. The display includes an array of pixels and a control system for adjusting content data signals for the array of pixels to compensate for aging of the pixels in the array. The control system measures a parameter of at least one of the pixels in the array via a read input of the at least one of the pixels. The controller determines the effect of the localized phenomena on the pixel using the parameter. A characteristic is measured for at least one of the pixels in the array via the read input of the at least one of the pixels. The measured characteristic is adjusted to reduce the effect of the localized phenomena. An adjusted aging compensation value based on the adjusted measured characteristic is calculated by the controller. The aging compensation value is applied to a data content signal to at least one of the pixels.
