Embodiment 1

[0035] figure 1 It is a top view of the touch substrate provided in Embodiment 1 of the present invention, as shown in figure 1 As shown, the touch control substrate is divided into a touch area TA and a frame area BA, and the frame area BA includes a light-shielding sub-area SA and a light-filtering sub-area IR for passing light of a predetermined wavelength band. figure 2 is the border area when the first stacked structure is adopted figure 1 The sectional view of the AA line in the middle, image 3 is the edge of the border area when the second stack structure is adopted figure 1 Sectional view of line AA in middle. Such as figure 2 with image 3 As shown, the touch substrate includes a substrate 1, a light-shielding layer 2 disposed on the substrate 1, and a light-filtering ink layer 3 disposed on the side of the light-shielding layer 2 away from the substrate 1, the light-shielding layer 2 and the light-shielding ink layer 3 are located in the frame area BA, the l...

Embodiment 2

[0060] Embodiment 2 of the present invention provides a touch device, which includes the above touch substrate. The touch device further includes a sensor corresponding to the filter sub-region, and the sensor is located on a side of the filter ink layer away from the substrate. The sensor may specifically be a camera, a light sensor, a distance sensor, and the like.

[0061] In order to enable the touch device to have the functions of touch and display at the same time, further, the touch device further includes a display panel, the touch substrate is located on the light emitting side of the display panel, and the touch substrate of the touch substrate is The control area corresponds to the display area of ​​the display panel, and the frame area of ​​the touch substrate corresponds to the non-display area of ​​the display panel.

[0062] Since the frame area of ​​the touch substrate provided by the present invention can realize one color, therefore, in the touch device usin...

Abstract

The present invention provides a touch substrate and a touch device. The touch substrate includes a touch area and a frame area. The substrate includes a substrate, a light-shielding layer and a filter ink layer arranged on the substrate, and the filter ink layer is located on the side of the light-shielding layer away from the substrate; the light-shielding layer is located on the side of the light-shielding layer area, the filter ink layer is located in the frame area and at least covers the filter sub-area; the lightness difference between the light-shielding sub-area and the filter sub-area is less than 3.6. The present invention can realize the integral color of the frame area of ​​the touch substrate, thereby bringing good visual experience to the user.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch substrate and a touch device. Background technique [0002] With the development of science and technology, the application of touch screen is more and more extensive. The frame position of the touch screen is usually provided with an infrared filtering (Infrared filtering, IR) hole, and the infrared filtering hole is provided with a distance sensor and / or a light sensor, so as to use the reflection of infrared rays to perform distance detection and / or monitor the brightness of the external environment. detection. In the current touch screen, the difference between the color of the infrared filter hole and the rest of the frame is obvious, and the infrared filter hole cannot be well hidden. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art, and proposes a touch substrate and a touch d...
