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 content data signals for the array of pixels using original aging compensation values to compensate for aging of the pixels in the array, said method comprising;
- determining an effect of a localized phenomena on an effected pixel in the array of pixels based on a change in a parameter of the effected pixel;
adjusting the original aging compensation value as a function of the change in the parameter associated with the localized phenomena to reduce the effect of the localized phenomena on the effected pixel;
applying the adjusted aging compensation value to a content data signal for the effected pixel; and
applying one of the original aging compensation values to a content data signal for each pixel not effected 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.

10. A display device comprising:
-
a display array including a plurality of pixels, the plurality of pixels each including a write input to write data content and a read input; and a controller coupled to the display array, the controller operable to; adjust content data signals for the array of pixels using an aging compensation value for each pixel; determine an effect of a localized phenomena on an effected pixel in the array of pixels based on a change in a parameter of the effected pixel; adjust the aging compensation value as a function of the change in the parameter associated with the localized phenomena to reduce the effect of the localized phenomena on the effected pixel; apply the adjusted aging compensation value to a content data signal to the effected pixel; and applying one of the original aging compensation values to a content data signal for each pixel not effected by the localized phenomena. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
