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.
