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.

The embodiments of the present invention provide a color filter (100) integrated with a sensor (60) array and methods of fabricating the same. By integrating the sensor (60) array with the color filter (100), the overall cost of the display is reduced. Moreover, the integration allows the sensor (60) array to be used like a touch screen (110) for data input. As a further benefit, the integration allows the color filter (100) to serve as a light shield thus eliminating the need for a separate light shield for the sensor array.

摘要:
Emission from a pixel is received by a sensor. The sensor is coupled to a control unit that receives or determines a value of the sensor's measurable parameter during operation of the pixel. A target value is coupled to the control unit, allowing the control unit to compare the measurable sensor parameter and the target value. The control unit is coupled to a pixel driver operable to alter the emission from the pixel. The pixel driver may vary the emission from the pixel until the measurable sensor parameter indicates that the target value has been achieved. The target value may be determined based on a calibration of the sensor. A plurality of target values may be stored in a look-up table. Passive and active matrix displays may be controlled in accordance with methods and apparatuses of the invention.
