Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0024] In the existing technology, the advantages of data transmission through LIFI are mainly reflected in fast transmission rate, wide frequency range, high confidentiality and security, no electromagnetic radiation, rich spectrum, high density, low cost, green and low energy consumption, etc. . The way of data transmission through LIFI is usually: by adding a microchip to the light bulb used for indoor lighting or the light bulb usually used as a flashlight in the mobile terminal, so that the light bulb flashes...

The embodiment of the invention discloses a mobile terminal and a LIFI signal transceiving method of the mobile terminal. The mobile terminal comprises a display device; the display device comprises multiple light emitting components and a LIFI signal sending control module; the LIFI signal sending control module is electrically connected with at least one light emitting component; the display device is used for controlling the multiple light emitting components to emit light according to a display signal, and displaying a picture to be displayed; and simultaneously, the display device is alsoused for controlling the light emitting component electrically connected with the LIFI signal sending control module to emit light according to a LIFI sending signal of the LIFI signal sending control module, so that a first LIFI signal is sent, wherein the light emitting component used for sending the first LIFI signal is at least one light emitting component in the multiple light emitting components used for displaying the picture to be displayed. Compared with the prior art, the mobile terminal provided in the embodiment of the invention can send the first LIFI signal while displaying thepicture to be displayed through the display device; and simultaneously, the security of the optical communication mode is easily improved.
Description
technical field [0001] The present invention relates to the technical field of visible light communication, in particular to a mobile terminal and a method for transmitting and receiving LIFI signals of the mobile terminal. Background technique [0002] With the development of mobile terminal technology, users have higher and higher requirements on data transmission speed and data transmission security of mobile terminals. Visible light wireless communication technology, also known as "light fidelity technology" (LIFI), is a wireless transmission technology that utilizes the visible light spectrum (such as the spectrum of illumination light emitted by a light bulb in a room) for data transmission. This technology transmits data by changing the flashing frequency of light bulbs, and the data transmission speed can reach 100GB. [0003] Typically, light bulbs can be used to send data by adding a microchip to the light bulb so that the light bulb blinks at a very high frequenc...
