Problems solved by technology

In addition, the pixels in the display panel are also periodically arranged, and the superposition of these two periodic patterns can easily form moiré patterns (moiré patterns are mainly caused by the interference of two periodic patterns in spatial positions. For example, when using a camera to shoot a computer monitor, there will be irregular graphics), which brings inconvenience to users
At the same time, since the conductive film is an independent unit, there is a gap between the two units, and the position of the gap is a glass substrate. The refractive index of the glass substrate is about 1.52, and the refractive index of the conductive film is about 1.9-2.0. It is not difficult to see The difference in refractive index between the two is large, so it will affect the display effect

Embodiment 1

[0032] to combine figure 1 As shown, this embodiment provides a touch control substrate, including a base 10 and a plurality of touch electrode blocks 11 disposed on the base 10, that is, the touch control substrate is a self-capacitive touch control substrate. In particular, a filling block 12 is provided between each touch electrode block 11 of the touch control substrate of this embodiment, and the material of the filling block 12 has a refractive index n 3 , the refractive index n of the material of the substrate 10 1 , the refractive index of the material of the touch electrode block 11 is n 2 , and|n 2 -n 3 |2 -n 1 |.

[0033] In the existing touch substrates, the substrate 10 is usually made of glass, and its refractive index is quite different from that of the touch electrode block 11, which makes the etched lines more obvious and affects the user's viewing effect. However, in this embodiment, a filling block 12 is provided between each touch electrode block 11, ...

Embodiment 2

[0040] This embodiment provides a method for preparing a touch substrate, which can be used to prepare the touch substrate in Embodiment 1. The preparation method includes: a step of forming a touch electrode block 11 on a substrate 10; a step of forming a filling block 12 between any two adjacent forests of the touch electrode blocks 11; wherein, the filling block 12 The refractive index of the material is n 3 , the refractive index of the material of the substrate 10 n 1 , the refractive index of the material of the touch electrode block 11 is n 2 , and|n 2 -n 3 |2 -n 1 |.

[0041] In the existing touch substrates, the substrate 10 is usually made of glass, and its refractive index is quite different from that of the touch electrode block 11, which makes the etched lines more obvious and affects the user's viewing effect. However, in this embodiment, a filling block 12 is provided between each touch electrode block 11, and the material of the filling block 12 has a ref...

Embodiment 3

[0054] This embodiment provides a display device, which includes the touch substrate in Embodiment 1.

[0055] Since the display device in this embodiment includes the touch substrate in Embodiment 1, that is, a filling block 12 is provided between each touch electrode block 11, and the material of the filling block 12 has a refractive index n 3 , the refractive index n of the material of the substrate 10 1 , the refractive index of the material of the touch electrode block 11 is n 2 , and the relationship between these three materials satisfies |n 2 -n 3 |2 -n 1 |, that is, the difference between the refractive index of the material of the filling block 12 and the material of the touch electrode block 11 is smaller than the difference between the refractive index of the material of the base 10 and the material of the touch electrode block 11, and the refractive index of the material determines its reflection Therefore, the reflectivity of the material of the filling block...

Abstract

The invention provides a touch substrate, a preparation method thereof, and a display device, which belong to the field of display technology. The touch substrate of the present invention includes a base, a plurality of touch electrode blocks arranged on the base, and a filling block is arranged between any two adjacent forests of the touch electrode blocks; wherein, the filling blocks The refractive index of the material is n 3 , the refractive index of the substrate material n 1 , the refractive index of the material of the touch electrode block is n 2 , and|n 2 ‑n 3 |<|n 2 ‑n 1 |. In the present invention, a filling block is set between each touch electrode block, and |n 2 ‑n 3 |<|n 2 ‑n 1 |, that is, the difference between the refractive index of the material of the filling block and the material of the touch electrode block is smaller than the difference of the refractive index of the material of the base material and the touch electrode block, and because the refractive index of the material determines its reflectivity, the filling The reflectivity of the block material is not much different from that of the touch electrode block. Therefore, the touch control substrate in the present invention has a better shadow elimination effect.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a touch substrate, a preparation method thereof, and a display device. Background technique [0002] Touch technology has been widely used in various display modes. Compared with traditional displays that only provide display functions, a display panel with a touch function can enable information interaction between a user and a display control host. Therefore, the touch display panel can completely or partly replace common input devices, so that the existing display panel can not only display but also be controlled by touch. [0003] At present, the most widely used touch display panel is the capacitive touch display panel. According to the relative position of the capacitive touch unit and the array substrate (TFT substrate) and packaging substrate in the display panel, it can be divided into embedded type, external embedded type and plug-in type. three kinds. So...
