DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to solve the problem that the conventional arrangement manner for an antenna restricts the appearance and material designing for a terminal in the related art, the embodiments of the disclosure provide a touch screen and a terminal. Wires are arranged on a conducting layer of the touch screen to realize a function of the antenna, so that the terminal with the touch screen can achieve better antenna radiating performance, and can also have no limitation on the appearance design of the terminal. Embodiments of the disclosure will be described below with reference to the drawings in the embodiments of the disclosure.

Embodiment 1

[0019] The embodiment of the disclosure provides a touch screen. As shown in FIG. 1, the touch screen includes a touch layer 6, a conducting layer 7 and substrate layer 8, which are laminated and matched in sequence.

[0020] In the embodiment, an antenna radiating body, and an antenna signal line and a ground feeder line which are connected with the antenna radiating body are arranged on the conducting layer 7,

[0021] wherein when the antenna radiating body, and the antenna signal line and the ground feeder line which are connected with the antenna radiating body are arranged, a basic arrangement principle is that a baseband control line (wiring configured to realize a touch function) of the touch screen is avoided. Therefore, in the embodiment of the disclosure, the antenna radiating body, the antenna signal line and the ground feeder line are arranged in a non-display area on the conducting layer. A touch screen on a mobile phone terminal is taken as an example, so the antenna radiating body, the antenna signal line and the ground feeder line may be arranged in a non-display area which is positioned above a display area of the mobile phone terminal, as shown in FIG. 2, or the antenna radiating body, the antenna signal line and the ground feeder line may be arranged in a non-display area which is positioned below the display area of the mobile phone terminal, as shown in FIG. 3.

[0022] In addition, along with development of touch screen technology, the touch screen may be bent. FIG. 4 is a simple bending diagram showing a touch screen. In the figure, the touch screen may be bent in leftward, rightward, upward and downward directions, and in the figure, areas B, C, D and E are bent areas. At present, bending the touch screen is based on different purposes, wherein there are some conditions where the bent areas are only configured for display and not respond to a touch operation. At this moment, the antenna radiating body and antenna wiring may be arranged in a non-touch area in a display area of the conducting layer.

[0023] Alternatively, in the embodiment, the antenna signal line and the ground feeder line are led out through an FPC so as to be connected with a radio frequency chip, so an antenna radiating and receiving circuit is formed.

[0024] Alternatively, in the embodiment, a forming manner for the antenna radiating body arranged on the conducting layer includes, but not limited to: a spraying and coating manner, an electroplating manner or an implementable process for forming a conducting film of the touch screen.

[0025] According to the embodiment of the disclosure, wiring is performed on the conducting layer of the touch screen to realize the function of the antenna, and supports are provided for the terminal to achieve better antenna radiating performance of the terminal and have no limitation on the appearance design of the terminal.

Embodiment 2

[0026] The embodiment of the disclosure provides a terminal. The terminal includes the touch screen of embodiment 1, that is, the terminal of the embodiment improves a conventional antenna arrangement manner, and an antenna is arranged through the touch screen.

[0027] A connecting manner between the touch screen and an internal chip of the terminal will be described below.

[0028] As shown in FIG. 5, 1 is a main board of the terminal; 2 is a radio frequency chip arranged on the main board; 3 is a connector arranged on the main board; 4 is an FPC of the touch screen; and 5 is the touch screen with the antenna.

[0029] An antenna signal line and a ground feeder line which are arranged on a conducting layer in the touch screen 5 are connected with the radio frequency chip 2 on the main board 1 through the FPC 4 and the connector 3 so as to form a circuit.

[0030] The FPC 4 may include a touch signal of the touch screen 5, and when the touch signal is included, after the connector 3 is connected with the main board 1, the signal line of the touch signal is connected with a baseband processing chip. The antenna signal line is connected with the radio frequency chip 2.

[0031] In conclusion, according to the embodiments of the disclosure, the antenna radiating body is arranged on the touch screen of the terminal, so that an available space for the antenna is greatly utilized, and the thickness of the terminal and influences that the metal component affects the antenna are reduced. In addition, assembling procedures of the antenna are reduced, and the consistency for assembling the antenna is improved.
