The connection manner of the touch screen 1, the TFT module 2 and the backlight module 3 in this embodiment is the prior art, and will not be described in detail here.

In this embodiment, the touch screen 1 includes a TP Sensor11, a TP Lens12 and a TP FPC13, the TP Lens12 is disposed outside the TP Sensor11, an antenna 4 is disposed on the TP Sensor11, and the antenna 4 is connected to a front PCB of the in-vehicle entertainment system through the TP FPC13, so as to implement signal processing with a chip and a module circuit on the front PCB.

In this embodiment, as a preferred technical solution, TP Sensor11 is made of a glass material; therefore, the antenna 4 is etched on the front side or the back side of the TP Sensor11 by using an etching process, meanwhile, the circuit 5 is etched on the surface of the TP Sensor11 where the antenna 4 is located, one end of the circuit 5 is connected with the antenna 4, and the other end of the circuit 5 is connected with the TP FPC 13.

In this embodiment, it is preferable that the antenna 4 is etched on the front surface of the TP Sensor11 by using an etching process, the wiring 5 is also etched on the front surface of the TP Sensor11, one end of the wiring 5 is connected to the antenna 4, and the other end of the wiring 5 extends to the bottom end of the TP Sensor11 and is connected to the TP FPC 13.
