Abstract
A pixel structure of a display. A scanning electrode is provided to scan signals and a data electrode is used to provide data signals. Also, a first switch transistor comprises a first terminal for receiving the scanning signals and a second terminal for receiving the data signals, in which the first switch transistor outputs a switch signal in accordance with the scanning signal and the data signal. A display unit is coupled to the first switch transistor and outputs image data in accordance with the switch signal. A second switch transistor is coupled to the first switch transistor in which the second switch transistor becomes conductive according to the switch signal and a blanking signal provided by the exterior power so as to modify the image data.
