Abstract: An electronic device including a pixel is provided. The pixel receives a data signal and includes a driving transistor, an emitting circuit, and a reset circuit. A first source/drain of the driving transistor receives a first operation voltage. The emitting circuit is coupled to the driving transistor. The reset circuit is coupled to the first gate to set the voltage of the first gate. In a reset period, the voltage of the first gate is equal to a first predetermined voltage. In a write period, the voltage of the first gate is equal to a first difference between the first operation voltage and the threshold voltage of the driving transistor. In a display period, the voltage of the first gate is equal to the sum of the first difference and a second difference between the reference voltage and the data signal.
