Touch screen and electronic products with curved surface

Abstract

The invention provides a touch screen with a curved surface and an electronic product using the same. The touch screen includes a protective panel and a conductive film. The protective panel includes an integrally formed top plate and side plates. At least one section of the protective panel is facing The outer convex arc, the radius of curvature of the inner surface of the arc area is greater than 0.1mm, the conductive film is attached to the inner surface of the protective panel and covers the arc area of ​​the protective panel, the conductive film It includes a base layer and a transparent conductive layer formed on the base layer and away from the side of the protection panel. When the protective panel of the present invention is assembled with the casing of the electronic device, the bottom end of the side plate of the protective panel is combined with the casing, so that the user will not be disturbed by the seam when performing touch operations on the top surface (operating surface) of the top panel , The touch feels better, and the user performance is better.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch screen with a curved surface and an electronic product. Background technique [0002] At present, touch screens are widely used in various electronic devices, such as cameras, mobile phones, MP4 and other electronic devices, which are mainly combined with display screens to perform graphic touch operations and receive input signals such as touch. [0003] Such as figure 1 As shown, the existing touch screen includes a protective panel 1 with protective and decorative effects and a conductive film attached to the protective panel. The conductive film includes a substrate and a conductive layer disposed on the substrate. The conductive layer includes a The transparent conductive pattern in the middle of the chip and the lead wire located at the edge of the substrate, the lead wire is electrically connected with the conductive pattern for transmitting electrical signals. ...

AI Technical Summary

Problems solved by technology

[0004] The existing protective panels are all flat, and the shape is relatively simple

At the same time, when the flat protective panel 1 is combined with the casing 3 of the electronic device, there are many seams 4 at the connection between the operation surface 5 of the protective panel 1 and the casing 3 (marked by the arrow in the figure below). The presence of the influence of the user's touch experience

Moreover, when the user slides their fingers, sweat and dirt are likely to remain on the seams, thereby breeding bacteria and affecting the user's health.
