Problems solved by technology

[0005] However, in order to meet the needs of convenient use and aesthetics, the current digital products have an increasingly urgent demand for narrow borders, that is, the invisible area has a very narrow width, or even zero borders.
However, the design frame of the above-mentioned prior art is wider, requires more raw materials, and makes digital products inconvenient to use and not attractive in appearance

Embodiment 1

[0038] figure 2 It is a schematic structural diagram of a narrow-frame touch screen provided in Embodiment 1 of the present invention. The narrow frame touch screen of this embodiment includes a substrate 10 , a conductive layer 20 and lead electrodes. The surface of the base 10 can be divided into a visible touch area 110 and an invisible frame area 120 , and the conductive layer 20 is arranged in the touch area 110 of the base 10 . The improvement of the touch screen in this embodiment is that the lead electrodes include electrically connected electrode wires 32 and external terminals 33, which are arranged in the frame area 120 of the substrate 10, and the electrode wires 32 are connected to the grid-shaped conductive layer 20. The edge is electrically connected.

[0039] In the narrow-frame touch screen provided in this embodiment, the pattern of the conductive layer 20 can be arranged in multiple rows or columns as required, and the conductive layer 20 of each pattern ...

Embodiment 2

[0047] image 3 The partial structural diagram of the narrow frame touch screen provided by Embodiment 2 of the present invention, this embodiment is based on the above Embodiment 1, and further includes a first connection line 34 connected between the conductive layer 20 and the electrode line 32, The first connection line 34 is connected to each grid line of the conductive layer 20 at the edge of the conductive layer 20, and the first connection line 34 is connected to each grid line of the electrode line 32 at the edge of the electrode line 32. line connected.

[0048] In this embodiment, in the form of setting connection lines, it is ensured that the wires of each grid can be connected to the first connection line 34 at the edges of the two grids, so as to realize the multi-point connection between the grid-shaped conductive layer 20 and the electrode lines 32. Electrical connection, improve electrical conductivity.

[0049] The first connection line 34 can be formed by ...

Embodiment 3

[0051] Figure 4 The partial structural diagram of the narrow frame touch screen provided by Embodiment 3 of the present invention. This embodiment is based on the above Embodiment 1, and is further provided with a transition section 35. The transition section 35 is a grid-like line located on the frame The region 120 is connected between the conductive layer 20 and the electrode lines 32 , and the grid density of the transition section 35 is greater than or equal to the grid density of the conductive layer 20 .

[0052] The transition section 35 in this embodiment can be regarded as extending from the edge of the grid of the conductive layer 20. Since there is usually a certain gap between the grid density of the conductive layer 20 and the grid density of the electrode lines 32, the grid lines The number of connection points between them is reduced, so a transition section 35 with a grid density between the two can be provided. The transition section 35 can be directly conn...

Abstract

The invention provides a narrow-frame touch screen which comprises a substrate, a conducting layer and a lead electrode. The substrate comprises a touch zone and a border zone, the conducting layer is laid in the touch zone of the substrate, the lead electrode comprises electrode wires and external binding posts and is laid in the border zone of the substrate, and the electrode wires are electrically connected with the edge of the conducting layer. By the arrangement, internal binding posts can be omitted, width of a border is decreased, and manufacturing materials are saved.

Description

technical field [0001] Embodiments of the present invention relate to touch input technology, and in particular to a narrow-frame touch screen. Background technique [0002] The touch screen is an external input device that is more and more widely used. It can realize input by lightly touching the touch panel with a finger or an electronic pen, making the human-computer interaction more direct, and has the characteristics of simplicity, speed, and humanization. [0003] Based on different working principles, there are various structures for touch screens to realize touch input. Among them, the transparent conductive film laid on the substrate is an important part of the touch screen, which is used to realize the collection and transmission of touch signals. In a conventional touch screen, the substrate is often divided into a visible touch area and an invisible frame area. The transparent conductive film includes a conductive layer located in the visible area and lead elect...
