Abstract
A display apparatus including a plurality of pixel circuit rows, where each pixel circuit row includes a plurality of pixel circuits, and each pixel circuit includes a light emitting component and a driving circuit. A gate voltage generation circuit generates a plurality of scan signals. A first scan signal and a second scan signal respectively control write circuits in driving circuits in a first pixel circuit row and a second pixel circuit row. The write circuit adjusts, based on a data voltage for controlling luminance of a light emitting component, a voltage at one end of a storage capacitor to a first voltage. The first scan signal further controls a reset circuit in a driving circuit in a second pixel circuit row, and the reset circuit resets the voltage at one end of the storage capacitor to a second voltage based on a reference voltage.
