Abstract: A display apparatus includes pixels, each of the pixels including a light-emitting diode, a first transistor connected to a driving voltage line and the light-emitting diode, a second transistor connected to the first transistor and the light-emitting diode, a third transistor connected to the second transistor and a first initialization voltage line, and a fourth transistor connected to the light-emitting diode and a second initialization voltage line. During a frame, each of the pixels operates in a first scan period and a second scan period. The first scan period includes a write-period in which a data signal is supplied and a first emission period in which the pixel is configured to emit light at a brightness corresponding to the data signal.
