P-48 / S. Maeyaert P-48: Pixel-based Optical Feedback to Correct Ageing and Non-uniformities in Large-area Displays

Abstract

Current AM addressing with peripheral drivers is not suited to tackle the problem of individual pixel deterioration for example due to aging or non-uniformity of different pixels in the display (a problem proportional to the size of the display). Therefore we pro-pose to integrate the driver electronics underneath each pixel, deviating from current display layouts. Thus it be-comes possible to implementing optical feedback for each pixel. A prototype of a driver with an optical feed-back loop was designed in a high voltage CMOS technology with integrated optical detectors. 1
