Abstract:
1. A display apparatus, comprising: a plurality of pixels, at least one of the plurality of pixels including: a scanner circuit including a first scanner, a second scanner, and a third scanner, wherein the holding capacitor and the second switching transistor are serially connected between the gate and the source of the driving transistor, the first scanner is configured to place the writing transistor into a conducting state during a signal writing period, the second scanner is configured to place the first switching transistor into a conducting state during a light emission period, the third scanner is configured to place the second switching transistor into a non-conducting state during the signal writing period, and into a conducting state during the light emission period, the first voltage line is configured to apply a fixed voltage to supply a current to the electro-optical device via the first switching transistor, and the first switching transistor is configured to control the light emission period of the electro-optical device to carry out duty driving.
