<P>PROBLEM TO BE SOLVED: To provide a design for an improved addressable display pixel to provide optical feedback. <P>SOLUTION: An image display includes an addressable image display pixel, having a substrate; a light emitter formed on the substrate; a photo-sensor formed on the substrate and optically coupled to the light emitter to detect light emitted by the light emitter to generate a feedback voltage signal in response to light emitted by the light emitter; and, a feedback readout circuit formed on the substrate and responsive to the feedback voltage signal to provide a feedback signal representing the light output of the light emitter, the feedback readout circuit including a transistor amplifier, means for resetting the readout circuit, and a select switch. <P>COPYRIGHT: (C)2003,JPO |
