Abstract
A display device and a compensation method of the display device are discussed. A sensing method for compensation, which is performed after a display device is powered off, includes displaying 1 black frame, charging a node M of a shift register A connected to a jth gate line of a display panel, charging a node M of a shift register B connected to a Kth gate line of the display panel, and sensing subpixels connected to the jth gate line and then sensing subpixels connected to the Kth gate line.
Claims17
A sensing method for compensation, which is performed after a display device including a display panel is powered off, the sensing method comprising:
- displaying one black frame;
- charging a node M of a first shift register connected to a jth gate line of the display panel;
- charging a node M of a second shift register connected to a Kth gate line of the display panel;
- and
- sensing subpixels connected to the jth gate line and then sensing subpixels connected to the Kth gate line.
A display device which performs sensing for compensation, which is performed after the display device is powered off, the display device comprising:
- a display panel including a plurality of subpixels;
- a gate driver which is connected with the subpixels through gate lines including a jth gate line and a Kth gate line;
- and
- a data driver which is connected to the subpixels through a data line,
- wherein the gate driver comprises:
- a first shift register which receives an RST2 signal in a global way, receives an LSP A signal and an RST1 A signal in a local way, and is connected with the jth gate line;
- and
- a second shift register which receives the RST2 signal in a global way, receives an LSP B signal and an RST1 B signal in a local way, and is connected with the Kth gate line.
