Abstract

The invention discloses a light-emitting driving circuit, a display panel and a display device. The light-emitting driving circuit comprises a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a sixth transistor and a first capacitor. According to the invention, the light-emitting drive circuit comprises six transistors and one capacitor; the connection relationship between the six transistors and one capacitor is set; the light-emitting driving circuit is ensured to output an enable signal for controlling the pixel driving circuit to accurately enter a light-emitting stage; compared with the prior art, the number of transistors and capacitors in the light-emitting drive circuit is reduced, the space, occupied by the light-emitting drive circuit, of a non-display area of the display panel is reduced, implementation of a narrow frame of the display panel is facilitated, and the cost of the display panel is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a light-emitting driving circuit, a display panel and a display device. Background technique [0002] Organic light-emitting displays are one of the hotspots in the field of display research today. Compared with liquid crystal displays, organic light-emitting displays have the advantages of low energy consumption, low production cost, self-illumination, wide viewing angle and fast response speed. [0003] The organic light emitting display panel not only includes an organic light emitting diode (Organic Light Emitting Diode, OLED), but also includes a pixel driving circuit that can provide conditions for the continuous lighting of the OLED. In order to ensure that the pixel drive circuit can drive the OLED to emit light normally, it is necessary to provide the pixel drive circuit with gate drive signals and enable signals of corresponding levels at diff...
