Embodiment 1

[0030] This embodiment provides a touch panel, such as figure 1 As shown, it includes a substrate 1 and a touch electrode 2 disposed on the substrate 1. A light processing structure 3 is arranged on the surface of the touch electrode 2. The light processing structure 3 can scatter the light irradiated thereon to reduce touch. Control the reflection of light on the surface of electrode 2.

[0031] By setting the light processing structure 3, the light irradiated on the surface of the touch electrode 2 can be scattered to reduce the reflection of the light on the surface of the touch electrode 2, thereby improving the display brightness of the display panel using the touch panel, thereby reducing The decrease in brightness of the display panel using the touch panel was tested outdoors.

[0032] In this embodiment, the light processing structure 3 includes a plurality of protrusions 31 , and the plurality of protrusions 31 are uniformly distributed on the surface of the touch el...

Embodiment 2

[0047] This embodiment provides a touch panel, which is different from Embodiment 1, such as image 3 As shown, the surface of the touch electrode 2 is the surface of the touch electrode 2 located on the light emitting side 4 and the light entering side 5 of the touch panel. That is, the surfaces of the touch electrodes 2 on the light-emitting side 4 and the light-receiving side 5 of the touch panel are both provided with light processing structures 3 (ie, a plurality of raised portions 31 ).

[0048] The setting of the raised portion 31 on the surface of the touch electrode 2 on the light incident side 5 of the touch panel can make the surface of the touch electrode 2 on the light incident side 5 of the touch panel rough, so that the light irradiated on the light incident side 5 of the touch panel The light on the surface of the touch electrode 2 is scattered, which reduces the reflection of the light on the side surface of the touch electrode 2, thereby improving the display...

Embodiment 3

[0052] This embodiment provides a display panel, including the touch panel in any one of Embodiments 1-2.

[0053] The display panel is an organic electroluminescence panel or a liquid crystal panel.

[0054] By adopting the touch panel in any one of the embodiments 1-2, the display brightness of the display panel is improved, especially the display brightness of the display panel is improved when the display panel is displayed outdoors, thereby improving the display effect of the display panel.

Abstract

The invention provides a touch panel, a preparation method thereof, a display panel and a display device. The touch panel comprises a substrate and a touch electrode arranged on the substrate, wherein a light processing structure is arranged on the surface of the touch electrode and can make light irradiated onto the structure scattered so as to decrease light refection of the surface of the touch electrode. The touch panel can make the light irradiated onto the surface of the touch electrode scattered by arranging the light processing structure so as to decrease light refection of the surface of the touch electrode, accordingly the display brightness of the display panel of the touch panel is improved, and thus the brightness reduction degree when the display panel of the touch panel is used outdoors is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a touch panel and a manufacturing method thereof, a display panel and a display device. Background technique [0002] In recent years, displays have been gradually developed from Cathode Ray Tube (CRT) displays and Liquid Crystal (LCD) displays to Organic Light-Emitting Diode (OLED) displays. The OLED display can realize a flexible display (Flexible Display). Setting the touch panel on the OLED display panel can realize the touch display of the OLED display panel. [0003] However, since the touch electrodes in the touch panel arranged on the OLED display panel adopt Metal Mesh, the light incident on the surface of the touch electrodes from the external environment will be reflected, which makes the light output side of the touch panel The light reflectance will increase by more than 7%, resulting in a significant decrease in the brightness of the OLED display panel w...
