Meanwhile, the advantage of wireless signal transmission by using visible light as a carrier is obvious, and the available spectrum resources can be expanded by using the visible light for wireless signal transmission, so that the limits on the authorization, management and the like of the spectrum resources are reduced; electromagnetic radiation is not easy to generate, and the anti-interference performance is strong; moreover, as the transmission medium is visible light which cannot penetrate through a building, the safety of wireless data can be improved; and fast network establishment is supported, so that a new choice is provided for short-distance wireless communication.

As can be seen from the above, in the electronic apparatus 1 provided in the embodiment of the present application, the modem 101 modulates the first signal to obtain the visible light emitting signal, the at least one light emitting unit 1021 of the transmitting antenna 102 can emit the visible light emitting signal, and the at least one light sensing unit 1031 of the receiving antenna 103 of the electronic apparatus 1 can send the visible light receiving signal to the modem 101 after receiving the visible light receiving signal, so that the modem 101 demodulates the visible light receiving signal to obtain the second signal. Since the at least one light emitting unit 1021 can emit a visible light emitting signal by emitting light, compatibility of illumination with wireless communication is achieved; and at least one light sensing unit 1031 can receive the visible light receiving signal in a photoelectric sensing manner, and because the light sensing units and the light emitting units have simple structures and low requirements on a supporting circuit, the electronic device 1 provided by the embodiment of the application can not only realize the transceiving processing of the 6G visible light signal, but also reduce the cost of transceiving the 6G wireless signal by the electronic device 1, and also reduce the influence degree of transceiving the 6G visible light signal on the circuit structure of the electronic device 1.

In the electronic device 1 provided in the embodiment of the present application, the at least one light-emitting unit 1021 may include at least one of the following: the display device comprises a display screen of the display device, a flash lamp and an indicator lamp.

In another embodiment of the present application, if it is necessary to transmit a visible light emission signal, it may be determined that a light-emitting unit that is currently already in an illuminated state among the plurality of light-emitting units in the electronic device 1 is a transmission antenna of the visible light emission signal. That is, the priority of the visible light emission signal emitted by the light emitting unit in the lit state is higher than the priority of the visible light signal emitted by the light emitting unit in the unlit state, so that the influence of the light change caused by the fact that the light emitting unit has to be lit because of the emission of the visible light emission signal to the user using the electronic device 1 can be effectively reduced.

For example, if the lighting unit currently in the lighting state is single, determining that the single lighting unit in the lighting state is used for emitting the visible light emission signal; if the number of the lighting units in the lighting state is multiple, it can be determined that the lighting units in the lighting state simultaneously emit visible light emission signals, and at this time, the transmitting antenna for emitting the visible light emission signals can be in a multi-antenna mode;

In still another embodiment of the present application, it may be determined whether there is a light-emitting unit that is already in an illuminated state among a plurality of light-emitting units in the electronic apparatus 1 first, and if there is no light-emitting unit that is already in an illuminated state, the light-emitting unit that is in a non-illuminated state is illuminated and transmits a visible light emission signal as a transmission antenna. Through the control process of the light-emitting unit, the influence of emitting visible light emission signals on brightness perception of a user can be effectively reduced; also, in the case where there are light-emitting units in the lit state, if the light-emitting units in the unlit state are lit, the influence of light emitted by these lit light-emitting units on the change in the ambient light brightness of the electronic apparatus 1 may be slight.

In the case where the electronic device 1 is a mobile intelligent terminal device such as a mobile phone, a tablet computer, and a smart television, the frequency of lighting the display screen as a data output channel is higher than the probability of lighting other light-emitting units, and in this case, if the display screen is in a data output state or a display state, the display screen emits a visible light emission signal through the array display unit in the display screen, so that the influence of having to light other light-emitting units due to emission of the visible light emission signal on the use of the electronic device 1 by the user can be effectively reduced.

Exemplarily, on the premise that the size of the display screen is equivalent to the size of the mobile electronic device and the display screen in the mobile intelligent device is maximized, the display area of the display screen is the largest area capable of being lighted in the mobile intelligent device.

In one embodiment, the display device may be independent of the electronic apparatus 1, but may be capable of establishing a communication connection with the electronic apparatus 1, so that the modem device 101 may transmit the visible light emitting signal to the display device to emit the visible light emitting signal through a display screen of the display device.

Based on the foregoing embodiment, the electronic device 1 provided in the embodiment of the present application further includes an obtaining device 104 and a control device 105. Fig. 2 is a second schematic structural diagram of the electronic device 1 according to the embodiment of the present application.

As shown in fig. 2:

In one embodiment, the control device 105 may restore the sensitivity of the at least one light sensing unit 1031 to the sensitivity before the at least one light sensing unit senses the visible light receiving signal after the at least one light sensing unit 1031 senses the visible light receiving signal with the target sensitivity or the current sensitivity to reduce the power consumption of the electronic apparatus 1.
