    • A pixel structure including a first switching transistor, a setting unit, a capacitor, a driving transistor, a second switching transistor and a luminous element is disclosed. The capacitor is coupled between a first and a second node. The first switching transistor transmits a data signal to the first node according to a scan signal. The driving transistor includes a threshold voltage and a gate coupled to the second node. The second switching transistor includes a gate receiving an emitting signal. The luminous element is coupled to the driving transistor and the second switching transistor in series between a first operation voltage and a second operation voltage. The setting unit controls the voltage levels of the first and the second nodes to compensate the threshold voltage of the driving transistor.
    • 公开了包括第一开关晶体管,设定单元,电容器,驱动晶体管,第二开关晶体管和发光元件的像素结构。 电容器耦合在第一和第二节点之间。 第一开关晶体管根据扫描信号将数据信号发送到第一节点。 驱动晶体管包括阈值电压和耦合到第二节点的栅极。 第二开关晶体管包括接收发射信号的栅极。 发光元件在第一操作电压和第二操作电压之间串联连接到驱动晶体管和第二开关晶体管。 设置单元控制第一和第二节点的电压电平以补偿驱动晶体管的阈值电压。
