Abstract

The invention discloses a GOA circuit and a display panel, the GOA circuit is provided with a plurality of cascaded GOA sub-circuits, an Nth row write-in control signal, an Nth row sensing control signal, an (N+1)th row write-in control signal and an (N+1)th row sensing control signal can be provided through the Nth-stage GOA sub-circuit, the single-stage GOA sub-circuit can meet the requirements of two rows of scanning signals at the same time, and the GOA sub-circuit can be applied to a display panel. The cascading number of GOA sub-circuits is reduced to a great extent, and implementation of a narrow bezel is facilitated.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to the field of GOA circuit technology, and in particular to a GOA circuit and a display panel. Background technique [0002] Due to the self-luminous properties of OLED (Organic Light-Emitting Diode, organic laser display) panels, future OLED panels must pursue thinness and variety of shapes. GOA (Gate Driver on Array, array substrate row drive) technology can achieve narrower and thinner borders, higher panel integration, richer product forms, simpler process flow, and more competitive future products; it can reduce equipment costs , improve the yield rate of the module, and save the cost of IC (Integrated Circuit, integrated circuit / chip). [0003] At present, the panel industry is accelerating its development towards high-definition and narrow borders. At this stage, the resolutions of panels on the market are mainly 2K and 4K. It has become a market trend to develop...
