When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a top view of a terminal shown in accordance with an exemplary embodiment, fig. 2 is an oblique view of a terminal shown in accordance with an exemplary embodiment, and fig. 3 is a cross-sectional view along AA' of the structure shown in fig. 1 (keys are not shown in fig. 3). The terminal may be an electronic device such as a mobile phone and a tablet computer, and the following embodiments are mainly exemplified in the case that the terminal is a mobile phone. As shown in fig. 1, 2 and 3, the terminal includes the following structure.

Lid 1, metal frame 2 and display module assembly 3 behind the metal, metal frame 2 with lid 1 contacts behind the metal, display module assembly 3 is provided with metal layer 31 in the one side of keeping away from the light-emitting side, metal layer 31 with first limit 21, second limit 22 and/or the third limit 23 of metal frame 2 contact, with the fourth side 24 of metal frame 2 is apart from the default distance.

In one embodiment, since the display module and the metal bezel are not integrated, in order to ensure that the metal layer on one side of the display module contacts with the bezel, a conductive structure may be disposed between the metal layer and the bezel, for example, a partial region of the metal layer and the bezel is welded, and the welding point is a conductive structure.

In one embodiment, the display module may include a display panel and a backlight module, and the metal layer may be disposed on a side of the backlight module away from the display panel, and may reflect a portion of light emitted downward from the backlight module toward the display panel.

In an embodiment, since the metal layer is away from the fourth edge of the metal frame by a predetermined distance, a gap 7 is formed between the metal layer and the fourth edge, a width d of the gap 7 may be set as required, and a length of the gap is approximately equal to a width of the mobile phone.

A key 4 disposed between the metal layer 31 and the fourth side 24, wherein the key 4 is a non-conductive structure;

and a first connection point 5 disposed in the metal layer 31.

In one embodiment, the first connection point may be disposed at an end of the metal layer near the fourth side.

A second connection point 6 provided in said fourth side 24 or in said metal back cover 1.

The following embodiments exemplify embodiments of the present disclosure mainly in the case where the second connection point is provided on the fourth side.

Wherein one of the first connection point 5 and the second connection point 6 is a feed point and the other is a ground point. I.e. the signal flow is from the fourth side to the metal layer or from the metal layer to the fourth side.

In one embodiment, the metal layer and the fourth edge are conducted through the first edge, the second edge and/or the third edge, so that the metal layer and the fourth edge can be approximately equivalent to a waveguide, and a gap can be formed between the metal layer and the fourth edge, which is equivalent to a slot formed on the waveguide, so that the metal layer and the fourth edge can be further equivalent to a slot antenna, that is, when a current signal input from a feed point propagates in the waveguide, the current signal is cut off by the slot and continues in the form of displacement current after encountering the slot, so that the slot is excited, and a part of the signal in the waveguide is radiated.

And a key of the terminal may be disposed in a gap formed by the metal layer and the fourth side, wherein the key may be a physical key, and a plurality of keys may be disposed in the gap.

According to the embodiment, a gap can be formed between the display module and the metal frame to form a gap antenna radiation signal, for example, as shown in fig. 1 and 2, since the gap is located on the front surface of the mobile phone and the display module and the metal frame are not integrated, a gap originally exists between the display module and the metal frame in the assembling process, the gap can be conveniently formed, and thus the gap antenna is formed.

Further, by disposing the keys in the gaps, the gaps can be sealed by the keys (and the frames of the keys, which are also non-conductive structures), so that the gaps hardly affect the appearance of the mobile phone. Compared with the mode of slotting the metal rear cover in the related art, the process is simpler, and the attractiveness is higher. And because the key is a non-conductive structure, the signal radiated by the slot antenna through the slot is not shielded, and the signal radiated by the slot antenna can be ensured to be good.

Optionally, as shown in fig. 3, an edge of the metal layer 31 close to the fourth edge 24 coincides with an edge of the display module 3 close to the fourth edge 24.

In one embodiment, the metal layer may be disposed along a side of the display module close to the fourth side, so that a distance between the metal layer and the fourth side may be ensured to be equal to a distance between the display module and the fourth side, and thus, a width of the slot may be conveniently adjusted by adjusting a position of the display module, and further, attributes such as input impedance of the slot antenna may be changed. Of course, the input impedance and other properties of the slot antenna can be adjusted by changing the positions of the feed point and the grounding point.

Fig. 4 is a top view of a terminal according to an exemplary embodiment, and fig. 5 is a schematic cross-sectional view along BB' of the structure of fig. 4 (keys are not shown in fig. 5). As shown in fig. 4 and 5, the fourth side 24 further includes a metal extension 241 extending toward the metal layer;

the metal layer 31 and the metal extension portion 241 are separated by the preset distance, and the key 4 is disposed between the metal layer 31 and the metal extension portion 241.

In one embodiment, since the width (for a rectangular key) or the diameter (for a circular frame) of the key is smaller than the distance between the display module and the fourth edge, i.e. there may still be an empty area between the fourth edge and the key, as shown in fig. 4. Therefore, the free area can also be made of a metal material, for example, the fourth side is extended to serve as the free area, i.e., the metal extension, so as to ensure that the slot is not too large to affect the radiation performance of the slot antenna.

Optionally, the terminal further includes:

In one embodiment, since the directivity of the signal radiated by the single slot is weak, the slot may be divided into a plurality of sub-slots by disposing at least one connecting piece between the fourth side and the metal layer, that is, between the slots, that is, the slot antenna array is formed, thereby improving the directivity of the signal radiated by the slot antenna.

Since the length of the slot in the slot antenna is equal to half of the wavelength of the radiation signal of the slot antenna, the length of each sub-slot in the antenna array can be adjusted according to the wavelength of the required radiation signal.

Optionally, the terminal further includes:

Optionally, the display module includes:

In one embodiment, the display module may be a liquid crystal display module, which includes a liquid crystal display panel and a backlight module, the backlight module may further include a light guide plate, a reflective layer, and a diffusion layer, and the metal layer may serve as the reflective layer, and is disposed on a side of the light guide plate away from the display module, for emitting light from the light guide plate in a direction away from the display module, and reflecting the light toward the display module.
