Array substrate, display panel and display device

Abstract

The invention provides an array substrate, a display panel and a display device. The array substrate comprises a non-display area, and the non-display area comprises a grid driving circuit area, a virtual pixel area and a connecting line area; the virtual pixel area is adjacent to a display area; the grid driving circuit area comprises a plurality of cascaded shifting registers and a plurality of grid driving circuit signal lines; the virtual pixel area comprises data lines arranged in a first direction and scanning lines arranged in a second direction, the data lines and the scanning lines are crossed to form a plurality of virtual pixels, and the first direction and the second direction are crossed; the connecting line area is located between the grid driving circuit area and the virtual pixel area; the connecting line area comprises a plurality of connecting lines; the array substrate further comprises a plurality of pressure sensing units located in the non-display area and a plurality of pressure sensing signal lines electrically connected with the pressure sensing units; at least part of the pressure sensing signal lines are used for multiplexing the grid driving circuit signal lines and / or the data lines of the virtual pixel area, and the design of a narrow frame is achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] At present, as an information input tool, a display panel with a touch function is widely used in various display products such as mobile phones, tablet computers, and information inquiry machines in halls of public places. In this way, the user only needs to touch the sign on the display panel with a finger to realize the operation of the electronic device, which eliminates the user's dependence on other devices (such as a keyboard and a mouse, etc.), and makes human-computer interaction easier. [0003] In order to better meet the needs of users, the array substrate of the display panel is usually provided with a pressure sensing unit for detecting the touch pressure value when the user touches the display panel, so that the display panel can not only collect touch position informat...

Problems solved by technology

[0004] The pressure sensing unit communicates with the outside through the pressure sensing signal line, for example, the pressure sensing unit obtains the operating voltage from the pressure sensing signal line, and transmits the detected pressure signal value through the pressure sensing signal line, but the pressure sensing Signal lines will occupy a certain non-display area, resulting in wider borders of array substrates, display panels, and display devices. This problem needs to be solved urgently
