Patent Images
1. An image display, comprising:
- a) a substrate;
b) an array of addressable light emitters formed on the substrate;
c) a drive circuit for driving the light emitters to emit light in an imagewise pattern;
d) one or more photo-sensors formed on the substrate and directly optically coupled to the light emitters in the array to detect light emitted by the light emitters and to generate a feedback signal in response thereto; and
e) a feedback control circuit responsive to the feedback signal for controlling the drive circuit to control the desired light output for each brightness level of the display.
