Problems solved by technology

[0006] However, due to the problem of its circuit structure, the existing scanning circuit is prone to the problem of logic confusion
In addition, when the threshold value of the transistor in the scanning circuit drifts, the scanning circuit cannot output normally, which makes the scanning circuit manufacturing process more complicated and strict.

Abstract

The present disclosure describes a shift register unit, an organic light-emitting display panel and a driving method. The shift register unit comprises a node potential controller and an output unit. The node potential controller comprises a first output end and a second output end. The output unit is configured to output, based on a first control signal from the first output end and a second control signal from the second output end, a first level signal or a second level signal. According to the solutions provided by the application, the potential of each node in the shift register unit is stable and controllable, and contributed to the avoidance of output logic execution problem in the shift register unit caused by unstable node potential when each control signal level of the shift register unit jumps.

Description

technical field [0001] The present disclosure generally relates to the field of display technology, and in particular, to a shift register unit, a register, an organic light emitting display panel and a driving method. Background technique [0002] With the continuous development of display technology, the size specifications of displays are changing rapidly. In order to meet the portability of electronic devices, the demand for smaller size display screens is increasing. [0003] At the same time, users also put forward higher requirements for the display quality of the display screen. For example, users tend to prefer displays with high PPI (Pixel per Inch, pixels per inch) to improve display accuracy and coherence. [0004] OLED (Organic Light-Emitting Diode, Organic Light Emitting Diode) displays are more and more widely used in various portable electronic devices because of their thinness, power saving and other characteristics. [0005] An OLED display generally inc...
