Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings.

[0034] The antennas of traditional electronic devices are usually made by etching or FPC, and then the completed antennas are attached to the touch screen. Since the antenna made by the above method is a visible component, it can only be attached to the non-visible area of ​​the touch screen, which undoubtedly makes the frame of the electronic device wider and cannot meet the requirement of high screen-to-body ratio.

[0035] In addition, for the touch screen, at present, the touch wiring of the touch screen is usually an electrode layer line formed of indium tin oxide (ITO) material. The ITO electrode layer circuit can be a conductive transparent circuit, and the transparent circuit can be used to sense the touch operation of a finger. However, the general square resistanc...

Abstract

The application provides a touch screen and electronic equipment. The touch screen includes an appearance structure layer, an antenna layer, a touch layer and a display screen which are stacked in sequence. Wherein, the touch layer is provided with a plurality of touch lines, and the plurality of touch lines cross each other, and form a plurality of touch sensing points in the touch area of ​​the touch layer. The antenna layer is provided with an antenna, and the projection of the antenna on the touch layer intersects with a plurality of touch sensing points to expose the touch sensing points. By arranging the antenna and the touch wiring on different layer structures, the antenna and the touch wiring can work independently during signal transmission without affecting each other, so as to achieve a better signal transmission effect. In addition, the arrangement position of the antenna on the antenna layer can also be adjusted so that the antenna does not occupy the space of the frame of the electronic device, which is beneficial to realize the design of the narrow frame of the electronic device.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to a touch screen and electronic equipment. Background technique [0002] At present, electronic devices (such as mobile phones, smart watches, etc.) are changing with each passing day. Taking mobile phones as an example, the requirements for the appearance and wireless performance of mobile phones are also constantly improving. Under the trend of large-screen mobile phones emphasizing high screen-to-body ratio, more antennas need to be placed in a smaller space to meet the frequency band requirements. [0003] In the prior art, the antenna is usually made by flexible printed circuit (FPC), laser direct structuring (LDS), or formed on the frame of the mobile phone for signal radiation. Among them, When the antenna is arranged on the frame of the mobile phone, the type of the antenna may be an inverted-F antenna (inverted-Fantenna, IFA), a monopole antenna (monopole) or a...
