Problems solved by technology

[0004] In order to accurately locate the touch position, the sensing trace is designed to be thinner. This structure makes the contact area between the sensing trace and the conductive lead at the end smaller, resulting in a higher contact area between the sensing trace and the conductive lead at the end. The resistance of the touch screen not only reduces the touch sensitivity of the touch screen, but also increases the power consumption of the touch screen

Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. A preferred embodiment of the invention is shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0026] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

Abstract

The invention discloses a touch sensing element. The touch sensing element comprises an insulating layer, a sensing layer and a driving layer, wherein the insulating layer is provided with a first surface and a second surface relative to the first surface; the sensing layer is located on the first surface, and is formed by sensing traces along the first dimension of a two-dimension coordinate system, and the sensing traces are mutually spaced and are not overlapped; the driving layer is located on the second surface, and is formed by the sensing traces along the second dimension of the two-dimension coordinate system, and the sensing traces are mutually spaced and are not overlapped; the sensing traces comprise a main trace and a connecting part formed at one end of the main trace, the connecting part is wider than the main line, and the connecting part is used for electrically connecting with an electric lead. The sheet resistance of the sensing layer can be reduced by the touch sensing element. The invention further provides a touch screen.

Description

technical field [0001] The invention relates to a touch sensing element and a touch screen using the touch sensing element. Background technique [0002] As a simple way of human-computer interaction, the touch screen is widely used in various electronic devices, such as mobile phones and IPADs. [0003] A touch screen generally includes a panel and a touch sensing element attached to one side of the panel. The touch sensing element consists of an insulating layer, a sensing layer and a driving layer located on two opposite surfaces of the insulating layer. The sensing layer includes several non-intersecting sensing traces extending along a first direction, and the driving layer includes several non-intersecting driving traces extending along a second direction. The first direction is not parallel to the second direction. The sensing trace and the driving trace are separated by the insulating layer, which is equivalent to two electrode plates of the capacitor. Each sensin...
