The antenna module 20 is integrated in the display area 101, and the orthographic projection of the antenna module in the screen body 10 is located in the non-light-emitting area between the pixel units, the design method does not affect the display effect of the display area 101, and the antenna module 20 can communicate through the space above the screen body 10 and has sufficient clearance space during communication, so that the communication quality is guaranteed. It should be noted that, the antenna module 20 is integrated in the display area 101, so that the antenna module 20 is disposed on the light-emitting side of the screen body 20, that is, the antenna module 20 is disposed above the screen body 20; the antenna module 20 may also be integrally disposed inside the screen body 20, and may be disposed on the same layer as the light emitting device layer of the screen body 20, or disposed on the same layer as the array layer of the screen body 20. In this embodiment, the antenna module 20 is disposed on the light-emitting side of the screen body 20. The rf module 30 is integrated in the non-display area 102 adjacent to the antenna module, and is responsible for transmitting and receiving information during communication, and electrically connected to the antenna module 20 to receive the antenna signal transmitted by the antenna module 20, so as to implement functions of rf transceiving, frequency synthesis, power amplification, and the like.
