Embodiment Construction

[0040] 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. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] As mentioned in the background, the in-cell touch display device is popular because the driving electrodes and / or sensing electrodes can be integrated inside the display panel, which can effectively reduce the thickness of the touch display screen and simplify the production process. . However, the size of the touch electrodes in the existing in-cell touch screen corresponds to the display area, resulting in poor touch sensitivity at the edge of the dis...

Abstract

The invention discloses an embedded touch display screen and a touch display device. The embedded touch display screen comprises a display panel and a touch electrode, wherein the display panel comprises a display region and a frame region; the touch electrode covers the display region and extends to the frame region. Known from the above contents, according to the technical scheme provided by the invention, the size of the touch electrode is enlarged; except for the to-be-covered display region, the coverage region of the touch electrode extends to the frame region; by virtue of enlarging the size of the touch electrode, the touch sensitivity of edge parts of the display region is improved on the premise of not influencing the area of the display region.

Description

technical field [0001] The present invention relates to the technical field of touch display, and more specifically, to an embedded touch display screen and a touch display device. Background technique [0002] The in-cell touch display device is popular because the driving electrodes and / or sensing electrodes can be integrated inside the display panel, which can effectively reduce the thickness of the touch display screen and simplify the production process. However, the size of the touch electrodes in the existing in-cell touch screen corresponds to the display area, resulting in poor touch sensitivity at the edge of the display area. Contents of the invention [0003] In view of this, the present invention provides an in-cell touch display screen and a touch display device, which expand the coverage area of ​​the touch electrodes to the frame area of ​​the display panel, so as to improve the touch sensitivity at the edge of the display area. [0004] In order to achiev...
