Abstract:
1. A display having a plurality of pixels, each pixel comprising: a light-emitting device configured to emit light in response to a current flowing through the light-emitting device, a luminance of the light-emitting device being dependent upon the current; a transistor 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 a control terminal of the transistor; and a first switching device 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 wherein the first 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.
