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.
