Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0030] figure 1 It is a schematic diagram of the circuit structure of a shift register provided by the embodiment of the present invention. This embodiment is beneficial to realize the narrow frame design of the OLED display panel. Refer to figure 1 , the shift register includes a first signal input terminal STV, a second signal input terminal CK and a third signal input terminal CKB, a first output terminal emit, a second output terminal Gout, a flip-flop D1, and a first NOR gate Q1;

[0031] The trigger signal ...

Abstract

The invention discloses a shift register, a display panel, a display device and a driving method. A first pulse signal is supplied from a first output end of a trigger of the shift register to a firstoutput end of the shift register, a second pulse signal is supplied by a first NOR gate of the shift register to a second output end of the shift register, a shift register circuit to supply the first pulse signal and another shift register circuit to supply the second pulse signal are set in the same shift register circuit, area of the display panel used by the shift register circuit is reduced,and narrow-bezel design can be achieved. In addition, the NOR gate circuit is used so that low level output of the shift register is more stable, and output of the second output end of the shift register is more benefited.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a shift register, a display panel, a display device and a driving method. Background technique [0002] With the development of display technology, the sizes and specifications of displays are becoming more and more diverse, and the borders are becoming narrower and narrower. Organic light-emitting diode (Organic Light-Emitting Diode, OLED) displays are more and more widely used in various portable electronic devices due to their thinness, lightness, power saving and other characteristics. [0003] An OLED display panel usually includes a pixel array and a pixel driving circuit that provides driving current to each OLED in the array. OLED display panels are generally provided with a plurality of shift registers for providing signals to the pixel driving circuit. The shift registers occupy a relatively large circuit layout, which is not conducive t...
