Abstract
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.
