<p>The embodiments of the present invention provide a flat panel display having a plurality of pixels, each comprising a light-emitting device configured to emit light in accordance with a current flowing through the light-emitting device, 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 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 locking the brightness at the specified level. The ramp voltage is generated in each pixel instead of in peripheral circuits, thereby reducing the number of conducting lines in the display.</p> |
