In the embodiment of the present invention, through the first housing 13 and the second housing 14, the first display 11 attached to the first housing 13 and the second display 12 attached to the second housing 14 can be turned over, so that the first display 11 and the second display 12 are folded or unfolded, that is, the mobile terminal is in a folded state or an unfolded state. Wherein, be provided with connection structure 15 between this first casing 13 and the second casing 14, realize turning over each other between first casing 13 and the second casing 14 through this connection structure, and then realize that first display screen 11 and second display screen 12 are folding or are expanded relatively, specifically, this connection structure 15 can be the hinge, accessible hinged joint between first casing 13 and the second casing 14 promptly. In the embodiment of the present invention, as shown in fig. 1, when the mobile terminal is in the unfolded state, the display screen orientation of the first display screen 11 is the same as the display screen orientation of the second display screen 12, and the first display screen 11 and the second display screen 12 are unfolded into a complete display screen; when the mobile terminal is in a preset folding state, the display orientation of the first display 11 is opposite to that of the second display 12. In an example, as shown in fig. 3, when the mobile terminal is in a preset folded state, the first display screen 11 and the second display screen 12 may be arranged facing each other, and at this time, the first housing 13 and the second housing 14 are arranged away from each other; in another example, when the mobile terminal is in a preset folded state, the first display 11 and the second display 12 may be disposed away from each other, and in this case, the first housing 13 and the second housing 14 are disposed facing each other.

Further, in the embodiment of the present invention, when the mobile terminal is in the preset folded state, the user generally has a small use requirement for data interaction of the mobile terminal, and generally only needs to ensure the basic communication and data service requirements of the mobile terminal, for example, it is required to ensure the basic network searching and incoming call standby use functions of the mobile terminal, at this time, in order to avoid the problem that the distance between the first antenna group and a part of antennas in the second antenna group is small, which causes the isolation of the antennas to be large, and the antennas interfere with each other, if the relative distance value between the antennas in the first antenna group and the antennas in the second antenna group is smaller than or equal to the preset distance value, that is, the relative distance value between the first antenna in the first antenna group and the second antenna in the second antenna group is smaller than or equal to the preset distance value, and enabling one of the first antenna and the second antenna to work in a target working frequency band, wherein only one of the first antenna and the second antenna works in the target working frequency band, namely only one of the first antenna and the second antenna normally communicates or interacts data, so that resonance of the first antenna and the second antenna in the same frequency band can be avoided, the isolation of the first antenna and the second antenna can be improved, and interference between the first antenna and the second antenna can be avoided, wherein the target working frequency band is the working frequency band for normal communication or data interaction of the antennas. In addition, the preset distance value may be obtained in advance through multiple sets of experimental data, or may be preset according to historical experience, and in one example, the preset distance value may be 1/4 wavelengths of a low frequency. In the embodiment of the present invention, in order to better meet the experience requirements of users on data services, each antenna group may include at least four antennas, that is, the first antenna group may include at least four antennas, and the second antenna group may include at least four antennas.
In the embodiment of the present invention, whether the mobile terminal is in the preset folded state or not may be determined by detecting a relative position state between the first display screen 11 and the second display screen 12 through an infrared sensor of the mobile terminal, where, based on a difference in a relative position between the first display screen 11 and the second display screen 12 when the mobile terminal is in the preset folded state, a setting position of the infrared sensor for detecting a relative position state between the first display screen 11 and the second display screen 12 is correspondingly different, that is, in an example, when the mobile terminal is in the preset folded state, the first display screen 11 and the second display screen 12 may be arranged facing each other, and at this time, the infrared sensor may be arranged on the same side of the mobile terminal as one of the display screens; in another example, when the mobile terminal is in a preset folded state, the first display screen 11 and the second display screen 12 may be arranged away from each other, and in this case, the infrared sensor may be arranged on a side of the mobile terminal opposite to one of the display screens.
