Problems solved by technology

In a single-layer film circuit structure, such as figure 1 As shown, the touch circuit 4 is usually formed of a transparent conductive material. Since the cross section of the touch circuit 4 faces the display side, there is an inclined section difference (slope angle) of the film layer of the touch circuit facing the human eye at the edge of the touch circuit 4. area), which causes visible light to enter the human eye after being reflected on the reflective surface, making the touch circuit pattern visible and affecting the final display effect of the display

Embodiment 1

[0048] This embodiment provides a touch screen, which eliminates the influence of the touch electrode pattern on the display effect of the display screen on the basis of ensuring the touch effect.

[0049] Such as figure 2 As shown, the touch screen includes an insulating layer 11 and a touch electrode 12, wherein at least one groove structure is opened on one side of the insulating layer 11, the touch electrode 12 is arranged in the groove structure, and the touch electrode 12 is vertically In the direction of the touch surface, the cross-sectional area corresponding to the top of the groove structure is larger than the cross-sectional area corresponding to the bottom of the groove structure. Here, the touch surface refers to the upper surface of the touch screen. Parts with electrostatic induction, such as human fingers, touch the corresponding functional area of ​​the touch surface to prompt the touch screen to respond to the corresponding function, thereby realizing the c...

Embodiment 2

[0072] This embodiment provides a touch screen. On the basis of ensuring the touch effect, the touch screen can effectively eliminate the reflection of the touch electrode, thereby eliminating the influence of the touch electrode pattern on the display effect of the display screen, and ensuring the display effect. .

[0073] Different from the touch screen in Embodiment 1, such as Figure 6 As shown, the insulating layer 11 in the touch screen of this embodiment is a transparent substrate, for example, the glass substrate near the display side of the display screen 2 can be directly used as the insulating layer 11 . Of course, the touch screen can directly form an inverted trapezoidal groove structure with a certain pattern on the display side substrate of the display screen. For example, taking a liquid crystal display screen as an example, a conductive film layer can be formed on the color filter substrate and passed The exposure and development process and the etching proc...

Embodiment 3

[0088] A display device, including the display panel in Embodiment 1 or Embodiment 2.

[0089] The display device can be any product or component with a display function such as a liquid crystal panel, an electronic paper, an OLED panel, a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, a navigator, and the like.

[0090] Because the display device adopts the above-mentioned display panel, it can ensure better display effect.

Abstract

The invention belongs to the technical field of display and particularly relates to a touch screen, a preparation method for the touch screen, a display panel and a display apparatus. The touch screen comprises an insulation layer and touch electrodes, wherein at least one groove structure is formed in one side of the insulation layer; the touch electrodes are arranged in the groove structures; and the cross section area, corresponding to the top of each groove structure, of each touch electrode in a direction perpendicular to a touch surface is greater than the cross section area, corresponding to the bottom of the groove structure, of the touch electrode. According to the touch screen, the influence of a touch electrode pattern on the display effect of a display screen is eliminated on the basis of ensuring the touch effect.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a touch screen and a preparation method thereof, a display panel and a display device. Background technique [0002] Touch screen is the latest information input device at present. It can realize human-computer interaction simply, conveniently and naturally, and provide people with a new way of multimedia human-computer interaction. Because it has the advantages of sensitive touch response and multi-touch support , which greatly satisfies people's visual and tactile enjoyment. [0003] In order to achieve thinner and lighter touch screens, structures that integrate touch panel functions with display screens have emerged, specifically including "In-cell" structures and "On-cell" structures. The "In-cell" structure is to embed the touch screen function into the pixel area of ​​the display screen, and the "On-cell" structure is to embed the touch screen function outsid...
