Problems solved by technology

[0003] At present, for organic light-emitting display panels, the 7T1C pixel drive circuit usually requires at least three gate drive circuits to provide control signals for it. In this way, three gate drive circuits need to be reserved in the non-display area, which is not conducive to Achieving Narrow Bezels

Abstract

The embodiment of the invention discloses a display panel, a driving method and a display device. It includes a gate drive circuit, a pixel drive circuit and a light emitting element; the pixel drive circuit includes: a drive transistor, a data writing module, a threshold compensation module, and a light emission control module; the transistor in the threshold compensation module is a P-type transistor, and the transistor in the light emission control module is an N-type transistor, or the transistor in the threshold compensation module is an N-type transistor, and the transistor in the luminescence control module is a P-type transistor; the control terminal of the threshold compensation module and the control terminal of the luminescence control module are electrically connected to the same gate drive circuit. The technical solutions provided by the embodiments of the present invention can reduce the number of gate drive circuits used to provide control signals for the pixel drive circuits, which is beneficial to saving costs and realizing narrow borders.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a driving method, and a display device. Background technique [0002] A light-emitting display panel usually includes a display area and a non-display area. The display area is provided with a plurality of pixel drive circuits and light-emitting elements. The pixel drive circuit is used to drive the light-emitting elements to emit light to display images; The control signal is provided for the pixel driving circuit, so that the light-emitting elements are illuminated row by row under the driving of the pixel driving circuit. [0003] At present, for organic light-emitting display panels, the 7T1C pixel drive circuit usually requires at least three gate drive circuits to provide control signals for it. In this way, three gate drive circuits need to be reserved in the non-display area, which is not conducive to Achieve narrow bezels. ...
