Title:
DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/097934
Kind Code:
A1
Abstract:
A display apparatus comprises: a display panel; and a drive unit which sets image data voltages to sub-pixel circuits of the display panel in a row line order during a data setting period, and drives the sub-pixel circuits such that a driving current is sequentially provided to inorganic light-emitting elements on the basis of a sweep signal and the image data voltages during a light-emitting period. The sub-pixel circuits comprise: a capacitor having one end to which the sweep signal is applied; and a first driving transistor connected to the other end of the capacitor, receiving the sweep signal through the capacitor in a light-emitting section, and controlling a time during which the driving current is provided to the inorganic light-emitting elements on the basis of the sweep signal. The drive unit applies a first voltage to the one end of the capacitor separately from the sweep signal in the data setting period.
