Title:
DISPLAY DEVICE AND DRIVING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/017042
Kind Code:
A1
Abstract:
A display device and a driving method therefor. The display device comprises: light emitting elements (10), pixel circuits (20), a scanning signal line (Gate), a data signal line (Data), an initial signal line (Vinit), a light emitting control line (EM), a first power source line (VDD), a first reset line (RST1), a second reset line (RST2) and a third reset line (RST3). Each pixel circuit (20) comprises: a first reset sub-circuit, configured to provide a signal of the initial signal line (Vinit) to a first node (N1); a node control sub-circuit, configured to provide a signal of the data signal line (Data) to a second node (N2), compensate the first node (N1) by means of the second node (N2) and a third node (N3) until the voltage of the first node (N1) satisfies a threshold condition, and provide a signal of the second node (N2) to the third node (N3); a light emitting control sub-circuit, configured to provide a signal of the first power source line (VDD) to the second node (N2), and provide a signal of the third node (N3) to the light emitting elements (10); and a second reset sub-circuit, configured to provide the signal of the initial signal line (Vinit) to the light emitting elements (10), the third reset line (RST3) connected to the pixel circuit (20) located in an ith row being connected to the first reset line (RST1) connected to the pixel circuit (20) located in an (i+1)th row.
