Abstract
A method of recovering a display having a plurality of pixels, each having a light emitting device and a driving transistor for driving the light emitting device. The driving transistor and the light emitting device are coupled in series between a first power supply and a second power supply. The method illuminates the semiconductor device while negatively biasing the pixel circuit with a recovery voltage different from an image programming voltage. The illuminating may follow a first cycle implementing an image display operation that includes programming the pixel circuit for a valid image and driving the pixel circuit to emit light according to the programming.
