Abstract

The invention provides an array substrate and a display device. The array substrate comprises a display region and a frame region, wherein the frame region surrounds the upper side, the lower side, the left side and the right side of the display region; touch electrodes which are distributed in an arrayed manner are arranged on the display region and are insulated from one another; at least one side of the frame region is provided with the touch electrodes; and each touch electrode is connected with a corresponding touch driving circuit through a corresponding touch wire. The touch electrodes which are distributed in the arrayed manner are arranged on the display region, and are also arranged on the frame region, and when a user touches edges of the frame region and the like, the touch position of the user can be sensitively detected through the touch electrodes arranged on the frame region. When the user touches the frame region or touches a portion between the frame region and the effective display region, the touch position can still be detected sensitively.

Description

technical field

[0001] The present invention relates to the technical field of touch screens, in particular to an array substrate and a display device. Background technique

[0002] In the prior art, touch screens are often used for display devices, and capacitive touch screens are commonly used. A touch screen generally includes a frame area and an active display area (AA, Active Area).

[0003] The touch electrode is arranged in the effective display area to realize the touch function and detect the touched position.

[0004] However, when the user touches the frame area or a position between the frame area and the effective display area, it may cause insensitive touch response.

[0005] Therefore, those skilled in the art need to provide an array substrate capable of sensitively detecting the touch position when the user touches the frame area, or touches between the frame area and the effective display area. Contents of the invention
