Embodiment Construction

[0059] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0060] The transistors used in all embodiments of this application 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, their source and drain can be interchanged. of. In the embodiment of the present application, 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. ...

Abstract

The invention provides a GOA device and a display panel. The GOA device comprises multiple stages of cascaded GOA units, and any stage of GOA unit comprises a first sub GOA unit and a second sub GOA unit. The first sub GOA unit is used for outputting a first scanning driving signal. The first sub GOA unit is used for outputting a first scanning driving signal, the second sub GOA unit is used for outputting a second scanning driving signal, the first sub GOA unit and the second sub GOA unit at least share part of signal lines, the first scanning driving signal is a display scanning driving signal, and the second scanning driving signal is a fingerprint scanning driving signal. According to the invention, the first sub GOA unit and the second sub GOA unit at least share a part of signal wires, the circuit layout of the display panel is simplified, meanwhile, the GOA device can achieve the functions of display scanning driving and fingerprint scanning driving at the same time, the space occupied by the GOA device in the display panel is reduced, the width of the GOA device is narrowed, and narrowing of a frame of the display panel is facilitated.

Description

technical field [0001] The present application relates to the display field, in particular to a GOA device and a display panel. Background technique [0002] GOA (Gate Driver on Array, integrated gate drive circuit) technology integrates the gate drive circuit on the array substrate of the display panel, thereby saving the part of the gate drive integrated circuit to reduce the product cost in terms of material cost and manufacturing process. cost. [0003] In order to control the normal display of the display panel in the existing display panel, a set of display driving GOA devices are respectively arranged on both sides of the display area of ​​the display panel. In order to realize the fingerprint recognition function of the display panel, it is necessary to install a set of fingerprint-driven GOA devices on both sides of the display panel, resulting in a large width of the GOA, and it is difficult to narrow the frame of the display panel. [0004] Therefore, there is a...
