ABSTRACT:
A pixel circuit includes a first transistor coupled to a supply voltage end, a second transistor coupled to a ground end, a storage capacitor, a third transistor coupled to a data end, a fourth transistor, a fifth transistor coupled to the second transistor and the second end of the storage capacitor, and a light-emitting element coupled to the fourth transistor. The first transistor is used for conducting a supply voltage from the supply voltage end in response to a trigger of an enable signal. The second transistor is used for conducting a ground voltage from the ground end when a scan signal voltage is triggered. The storage capacitor includes a first end and a second end coupled to the first transistor and the second transistor, respectively. The third transistor is used for conducting a data signal voltage when the scan signal voltage is triggered. The fourth transistor is used for generating a conducting current based on the data signal voltage when the scan signal voltage is not triggered. The fifth transistor is used for forming a conducting route between the storage capacitor and the fifth transistor. The light-emitting element is used for generating light based on the conducting current of the fourth transistor.
