Problems solved by technology

[0004] Therefore, it is necessary to provide a new bidirectionally scanable shift register circuit, which can avoid the shift due to the shift register unit of the last stage (the shift register unit of the last stage here is the last shift in the scanning direction) The increase in the bias time of the pull-up node in the register unit) causes the output signal of the last-stage shift register unit to appear low, so as to avoid the occurrence that a certain stage of shift register unit cannot achieve sufficient output after switching the scanning direction. The phenomenon that there is no output signal when the turn-on voltage is high, so as to avoid the phenomenon of abnormal display

Abstract

The invention relates to the technical field of display and especially relates to a shift register circuit, a driving method of the shift register circuit and a display device. The circuit comprises afirst switch unit, a second switch unit, a third switch unit, a fourth switch unit, a fifth switch unit, a sixth switch unit, a seventh switch unit and an eighth switch unit. The shift register circuit can prevent the phenomenon that some stage of shift register unit cannot reach enough start voltage and thus has no output signal after switching the scanning direction, thereby avoiding the phenomenon of display abnormality; and besides, through the first-eighth switch units, reliability of the shift register circuit is improved.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a shift register circuit, a driving method for the shift register circuit, and a display device. Background technique [0002] With the development of optical technology and semiconductor technology, flat panel displays represented by liquid crystal display (Liquid Crystal Display, LCD) and organic light emitting diode display (Organic Light Emitting Diode, OLED) have the advantages of light and thin, low energy consumption, fast response speed, color The characteristics of good purity and high contrast ratio occupy a dominant position in the display field. In recent years, display devices have shown a development trend of high integration and low cost. Using the shift register unit GOA to integrate the gate drive circuit in the peripheral area of ​​the array substrate can effectively reduce the manufacturing cost of the display device and improve the yield of the...
