Problems solved by technology

The inventor found that in the traditional shift register circuit, each shift register unit only provides signal input for the gate lines of a row of pixels. At this time, the number of GOA unit circuits needs to be consistent with the number of gate lines in the display area, so the resolution is getting better and better. The higher the value, the more and more GOA unit circuits are required, which is not conducive to the integrated design of products, especially not conducive to the realization of narrow bezel products

Embodiment Construction

[0100] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0101] The transistors used in all embodiments of the present invention can be thin film transistors or field effect transistors or other devices with the same characteristics. Since the source and drain of the transistors used here are symmetrical, there is no difference between the source and the drain. of. In the embodiment of the present invention, in order to distinguish the two poles of the transistor except the gate, one pole is called the source, and the other pole is called the drain. According to the form in the accompanying drawings, it is stipulated that the middle terminal of the transistor is the gate, the signal input terminal is the source terminal, a...

Abstract

The embodiment of the invention provides a shift register unit, a drive method, a shift register circuit and a display device, and relates to the field of manufacturing of the display. Output of two grid line signals can be achieved by one shift register unit, so that an integrated design of the circuit of a product is facilitated; and meanwhile, achievement of a narrow frame of the product is facilitated. The shift register unit comprises a first input module, a second input module, a first grid line drive signal module, a second grid line drive signal module, a pull-down module and a reset module. The embodiment of the invention is applied to manufacturing of the display.

Description

technical field [0001] The invention relates to the field of display manufacturing, in particular to a shift register unit, a driving method, a shift register circuit and a display device. Background technique [0002] In recent years, the development of displays has shown a trend of high integration and low cost. One of the very important technologies is the mass production of GOA (Gate Driver on Array, array substrate row drive). The gate switch circuit is integrated on the array substrate of the display panel by using GOA technology, so that the gate drive integrated circuit part can be saved, so as to reduce the product cost in terms of material cost and manufacturing process. The gate switch circuit integrated on the array substrate using the GOA technology is also called a GOA circuit or a shift register circuit. [0003] Wherein, the shift register circuit includes several shift register units, and each shift register unit corresponds to a gate line, and specificall...
