Abstract

The embodiments of the present invention provide a flat panel display (fig. 4c) having a plurality of pixels, each comprising a light-emitting device (514) configured to emit light in accordance with a current flowing through the light-emitting device, a transistor (512) coupled to the light-emitting device and configured to provide the current through the light-emitting device, the current increasing with a ramp voltage applied to control terminal of the transistor, and a switching device (522) configured to switch off in response to the luminance of the light-emitting device having reached a specified level, thereby disconnecting the ramp voltage from the transistor and locking the brightness at the specified level.. The switching device is further configured to stay off thereby allowing the luminance of the light-emitting device to be kept at the specified level until the pixel is rewritten in a different frame.
