Embodiment Construction

[0034] 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. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0035] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also 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 ill...

Abstract

A protection cover plate comprises a body, one side, close to a touch screen, of the body is divided into a display area and a shielding area, the shielding area surrounds the display area, a transparent conducting circuit is arranged on the display area, and a conducting leading wire is arranged on the shielding area. The conducting leading wire is electrically connected with the transparent conducting circuit, a cover bottom oil ink layer is arranged on the shielding area and covers the conducting leading wire, the transparent conducting circuit and the conducting leading wire are both attached to the inner surface of the body, and therefore the transparent conducting circuit and the conducting leading wire are electrically connected on the same plane. The problem that the transparent conducting circuit is easily broken down due to the height difference between the transparent conducting circuit and the cover bottom oil ink layer is avoided, and moreover the conducting leading wire and the cover bottom oil ink layer are identical in color. Therefore, when the touch screen is used, the conducting leading wire can not be distinguished out from the outer side of the protection cover plate, the attractiveness of the touch screen is prevented from being affected. The invention further provides the touch screen comprising the protection cover plate and a manufacturing method of the touch screen.

Description

technical field [0001] The invention relates to a protective cover, in particular to a protective cover, a touch screen and a manufacturing method of the touch screen. Background technique [0002] Electronic devices such as smartphones and tablets are equipped with touch screens. The touch screen includes a protective cover. The middle part of the protective cover is the display area, and the cover ink coated on the periphery of the display area forms a shielding area surrounding the display area to shield the internal circuits of the touch screen. In order to reduce the thickness of the touch screen and save materials, a transparent conductive line can be provided on the inner surface of the protective cover and located in the display area so that the protective cover also has the function of a touch sensor. At the same time, conductive leads are provided on the side of the cover ink in the shielding area away from the protective cover, and these conductive leads are con...
