Abstract

Disclosed are a display panel, a display device and a driving method thereof. The display panel includes a plurality of sub-pixel cells arranged in an array including N rows and M columns and a gate driving circuit. Each of the plurality of sub-pixel units includes a light emitting unit, a pixel driving circuit for driving the light emitting unit to emit light, and a sensing circuit for sensing the pixel driving circuit. The gate driving circuit includes N+1 sequentially arranged output terminals and is configured to output a gate scanning signal that turns N rows of sub-pixel cells of the array on line by line. The pixel driving circuit of the nth row sub-pixel unit and the nth output terminal of the gate driving circuit are connected to receive a gate scanning signal as a scan driving signal, and the sensing circuit of the nth row sub-pixel unit and the n+1 output terminal of the gate driving circuit are connected to receive a gate scanning signal as a sense driving signal. The display device using the display panel can reduce the frame size.

Description

technical field [0001] Embodiments of the disclosure relate to a display panel, a display device and a driving method. Background technique [0002] In the field of display, especially in OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display panels, the gate driving circuit is currently generally integrated in the GATE IC. The area of ​​the chip in IC design is the main factor affecting the cost of the chip. How to effectively reduce the chip area is a key consideration for technology developers. [0003] At present, the gate drive circuit for OLED is usually composed of three sub-circuits, that is, the detection circuit, the display circuit and the connection circuit (or gate circuit) that outputs the composite pulse of the two. Such a circuit structure is very complicated and cannot meet the requirements of the display. High resolution narrow bezel requirements for panels. Contents of the invention [0004] At least one embodiment of the present dis...
