The display area of the second portion 420 may also be used for displaying information, and the non-display area may also be used for disposing functional elements such as touch electrodes. The non-display area of the second portion 420 may be located at an edge of the second portion 420. For example, the non-display area of the second portion 420 may be proximate to the fourth side 422 of the second portion 420.

Wherein the electronic device 100 further comprises a second antenna radiator 90. The second antenna radiator 90 may be used to transmit radio frequency signals or receive radio frequency signals, and may also be used to transmit and receive radio frequency signals simultaneously. The second antenna radiator 90 is disposed in the first housing 10 or the second housing 20. For example, the second antenna radiator 90 may be disposed on the circuit board 50 within the first housing 10. For another example, a separate antenna bracket may be disposed in the second housing 20, and the second antenna radiator 90 may be disposed on the antenna bracket in the second housing 20.

The orthographic projection of the second antenna radiator 90 on the display screen 40 is located in a lateral non-display area of the first portion 410 or a lateral non-display area of the second portion 420. For example, the orthographic projection of the second antenna radiator 90 on the display screen 40 may be located in a non-display area at the second side 412 of the first portion 410, or may be located in a non-display area at the fourth side 422 of the second portion 420. That is, the orthographic projection of the second antenna radiator 90 on the display screen 40 is located at two opposite ends of the display screen 40 far away from the rotating shaft 30. Accordingly, the distance between the second antenna radiator 90 and the first antenna radiator 80 is large, and the isolation between the second antenna radiator 90 and the first antenna radiator 80 can be improved.

In some embodiments, control circuitry is also provided in the electronic device 100. Wherein the control circuit is disposed in the first housing 10 or the second housing 20.

Wherein, when the first portion 410 and the second portion 420 of the display screen 40 are in the folded state, the first portion 410 and the second portion 420 are close to each other as shown in fig. 4. When the first portion 410 and the second portion 420 of the display screen 40 are in the unfolded state, the first portion 410 and the second portion 420 are in the same plane, that is, an included angle between the first portion 410 and the second portion 420 is 180 degrees. Wherein transmitting the radio frequency signal comprises transmitting the radio frequency signal, receiving the radio frequency signal, and simultaneously transmitting and receiving the radio frequency signal.

In some embodiments, when the included angle between the first portion 410 and the second portion 420 is within a predetermined angle range, the first portion 410 and the second portion 420 of the display screen 40 may also be considered to be in the unfolded state, and the first portion 410 and the second portion 420 are approximately in the same plane. Wherein the preset angle range may be 150 to 200 degrees. That is, when the included angle between the first portion 410 and the second portion 420 is between 150 degrees and 200 degrees, it can be considered that the first portion 410 and the second portion 420 of the display screen 40 are in the unfolded state, and at this time, the control circuit controls the second antenna radiator 90 to transmit the radio frequency signal.

When the first portion 410 and the second portion 420 of the display screen 40 are in the folded state, the first portion 410 and the second portion 420 are close to each other, which may affect the antenna performance of the second antenna radiator 90. Thus, when the radio frequency signal is transmitted through the first antenna radiator 80, the communication stability of the electronic device 100 may be improved.

Similarly, when the first portion 410 and the second portion 420 of the display screen 40 are in the unfolded state, the rotation shaft 30 is in a state of being surrounded by the first portion 410 and the second portion 420. The antenna performance of the first antenna radiator 80 provided on the rotation shaft 30 is affected by the first portion 410 and the second portion 420. At this time, when the radio frequency signal is transmitted through the second antenna radiator 90, the communication stability of the electronic device 100 may be improved.

In some embodiments, a proximity sensor, such as an infrared sensor, an ultrasonic sensor, or the like, may be provided in the electronic device 100. The electronic device 100 may detect an angle between the first portion 410 and the second portion 420 of the display screen 40 through the proximity sensor, so as to determine whether the first portion 410 and the second portion 420 are folded or unfolded. Thus, the control circuit may control the first antenna radiator 80 or the second antenna radiator 90 to transmit a radio frequency signal according to the detected state between the first portion 410 and the second portion 420.

In some embodiments, with continued reference to fig. 11, electronic device 100 also includes signal source 83. The signal source 83 is disposed in the first housing 10 or the second housing 20. For example, the signal source 83 may be disposed on the circuit board 50 inside the first housing 10. For another example, in some embodiments, the circuit board 50 may be disposed inside the second housing 20, and the signal source 83 may be disposed on the circuit board 50.

The signal source 83 is connected to the first antenna radiator 80 and the second antenna radiator 90. Thus, the signal source 83 can feed a radio frequency signal to the first antenna radiator 80 or the second antenna radiator 90.

In some embodiments, referring to fig. 12, fig. 12 is an eleventh structural schematic diagram of an electronic device provided in an embodiment of the present application. Wherein the second antenna radiator 90 includes a third sub-antenna radiator 91 and a fourth sub-antenna radiator 92. The orthographic projection of the third sub-antenna radiator 91 on the display screen 40 is located in a lateral non-display area of the first portion 410. For example, the orthographic projection of the third sub-antenna radiator 91 on the display screen 40 is located in the non-display area at the second side 412 of the first portion 410. The orthographic projection of the fourth sub-antenna radiator 92 on the display screen 40 is located in a lateral non-display area of the second portion 420. For example, the orthographic projection of the fourth sub-antenna radiator 92 on the display screen 40 is located in the non-display area at the fourth side 422 of the second portion 420. Therefore, when the control circuit controls the second antenna radiator 90 to transmit the rf signal, the rf signal can be transmitted through the two

sub-antenna radiators

91 and 92 at the same time, and the efficiency of transmitting the rf signal can be improved.

In some embodiments, the first antenna radiator 80 may further include more than 2 sub-antenna radiators.

The sum of the number of the sub-antenna radiators included in the first antenna radiator 80 and the number of the sub-antenna radiators included in the second antenna radiator 90 may be 8, 12 or 16, that is, 8, 12 or 16 sub-antenna radiators are provided on the electronic device. These sub-antenna radiators may constitute a Multiple-Input Multiple-Output (MIMO) antenna, wherein there may be a plurality of sub-antenna radiators for simultaneously transmitting or receiving radio frequency signals. The mimo antenna may be used to transmit 5G rf signals. The antenna mechanisms in the mimo antenna are spaced apart from each other. The specifications (for example, length, width, material, and the like) of the antenna mechanisms in the mimo antenna may be the same or different.
