Shift register unit, register, organic light emitting display panel and driving method

Abstract

The invention discloses a shift register unit, a register, an organic light emitting display panel and a driving method. The shift register unit comprises a node potentiometric controller and an output unit; the node potentiometric controller comprises a first output end and a second output end; the output unit is used for outputting a first level signal or a second level signal on the basis of a first control signal output from the first output end and a second control signal output from the second output end. By the arrangement, nodes in the shift register unit are stable and controllable in electric potential, and the problem that the nodes are unstable in level jumping of the control signals in the shift register unit resulting in output logic confusion of the shift register unit can be solved; in addition, the shift register unit has robustness performance on threshold shift of transistors, normal work can still be performed within certain threshold shift range when threshold shift exists in the transistors, and complexity in technology of the shift register unit is lowered.

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 sizes and specifications of displays are changing with each passing day. In order to meet the portability of electronic devices, the demand for smaller display screens continues to grow. [0003] At the same time, users have also put forward higher requirements for the display quality of the display screen. For example, users tend to prefer high PPI (Pixel per Inch, pixels per inch) display screens to improve display accuracy and coherence. [0004] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode, Organic Light-Emitting Diode) displays are more and more widely used in various portable electronic devices because of their features such as thinness, lightnes...

AI Technical Summary

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.
