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