Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0037] As mentioned in the background technology, the touch accuracy of the existing display devices is low. The inventors found that the reason for this problem is that the touch area of ​​the existing display devices includes multiple touch units. The unit senses the capacitance change caused by the finger, and then judges whether the finger is touched, so as to determine the position of the finger touch. Since two adjacent touch units are very close to each other and have a parasitic capacitance Cm, there is a ...

Abstract

The embodiment of the invention discloses a display device. The display device comprises a display film layer, a touch driving module, a plurality of touch electrodes and a plurality of shielding structures, wherein the touch electrodes and the shielding structures are located on the same side of the display film layer; the vertical projections of the shielding structures on the display function layer are located between the vertical projections of at least part of the touch electrodes on the display function layer, and the touch electrodes are insulated from the shielding structures; the shielding structures and the touch electrodes are electrically connected with the touch driving module, and the touch driving module is used for detecting noise signals through the shielding structures and correcting touch signals detected on the touch electrodes according to the noise signals during touch position detection. According to the embodiment of the invention, the touch detection precision of the display device is improved.

Description
