Embodiment Construction
[0026] In order to facilitate the understanding of the present invention, the touch display screen and the touch display device will be more fully described below with reference to related drawings. Preferred embodiments of the touch display screen and the touch display device are given in the accompanying drawings. However, touch screens and touch display devices can be implemented in many different forms, and are not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the touch display screen and the touch display device more thorough and comprehensive.
[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be pr...

The invention relates to a touch display screen and a touch display device. The touch display screen comprises a cover plate, an adhesive layer attached to the cover plate, a touch sensor, a conductive medium and a substrate. The touch sensor comprises a carrier and a sensing electrode layer arranged on the carrier. The carrier is bonded to a side of the adhesive layer away from the cover plate; Aconductive medium is formed on a side of the carrier facing away from the adhesive layer; The substrate is bonded to the cover plate to form an airtight enclosure. The adhesive layer, the touch sensor and the conductive medium are all located in the enclosure. The substrate is provided with a binding region, and the binding region is electrically connected with the sensing electrode layer througha conductive medium. Since the functional layer of the touch sensor is not directly fabricated on the inner surface of the display panel on the substrate or the inner surface of the cover plate, butis arranged on the carrier and bonded to the cover plate through an adhesive layer, the whole structure is simple and easy to bind.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a touch display screen and a touch display device. Background technique [0002] With the development of touch display screens becoming more and more diversified, the position of touch panels relative to the display screen can be divided into plug-in type, integrated type and built-in type. Among them, the built-in touch display screen has the highest degree of integration. Has a lower package thickness. [0003] The touch function layer of the traditional in-cell touch screen is directly made on the inner surface of the display panel or the inner surface of the cover on the substrate, so that the in-cell touch screen has the problem of mutual interference between the touch signal and the display signal; In addition, the binding of the traditional in-cell touch screen is relatively difficult, resulting in high difficulty in production of the touch screen and low yield r...
