  • Pixel structure and driving method thereof
    Patent number: 9153173
    Abstract: A pixel structure and a driving method thereof are disclosed. The driving method includes following steps. During a first displaying frame period, a threshold voltage of a transistor for driving a light-emitting diode is stored in a first capacitor, and a first data voltage is stored in a second capacitor. The threshold voltage stored in the first capacitor is utilized for compensation during the first displaying frame period. During a second displaying frame period, a second data voltage is stored in the second capacitor, and the threshold voltage stored in the first capacitor during the first frame displaying period is still utilized for compensation during the second displaying frame period.
