ABSTRACT:
A picture quality control system can determine a location of a display panel defect. The system can calculate data used to compensate for the display defect and modulate the compensation data on a video signal to compensate for the defect. The defect may be associated with a pixel or with a display panel area. A picture quality system may include a memory and a compensation circuit. The memory may store compensation data that represents a panel defect location and/or a charge characteristic. The compensation circuit may process the compensation data to increase or decrease brightness information and/or component information of a video signal.
