Abstract

The invention provides a terminal device, comprising the following parts: a display module, comprising a display structure and a flexible circuit board; a metal structure, arranged between the displaystructure and the flexible circuit board and respectively attached to the display structure and the flexible circuit board, wherein the area of the attaching end surface of the metal structure the islarger than the area of the attaching end surface of the preset area of the flexible circuit board, and is smaller than the area of the attaching end surface of the display structure; a metal middleframe, comprising a groove and ends disposed on both sides of the groove, wherein the predetermined area of the flexible circuit board and the metal structure are disposed in the groove, and the endsare in contact with the display structure. The terminal device provided by the embodiment of the invention can reduce the stack thickness of the whole machine, provide a ground return path and excellent shielding performance, and can improve the temperature rise problem of the terminal device and improve the heat dissipation effect of the terminal device.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a terminal device. Background technique [0002] With the development of full-screen, the drive IC (integrated circuit) and FPC (Flexible Printed Circuit) of the display module are getting closer to the antenna, and the electromagnetic noise released by the display module is passed through the near field. (Magnetic / Electric Field) low-loss coupling to the antenna, resulting in a decline in the performance of the RF receiver, while the degree of interference becomes more and more serious with the evolution of the limit full screen. [0003] Full-screen design, the driver IC body of the LCM (Liquid Crystal Display Module, liquid crystal display module) and the FPC in the bending area are compressed to a distance of 0.2mm closest to the terminal communication antenna. Most of the interfered frequency bands are mainly concentrated in low-frequency CDMA (Code Divisi...
