Abstract

The invention provides a data transmission method and a mobile terminal. The data transmission method is applied to the mobile terminal, which is provided with a marker, on a shell body outside a display screen region; a light emitting source is arranged below the marker; the mobile terminal is used as a light signal transmitting end; the method comprises the following steps: converting data to be transmitted into an electric signal through a main control circuit and outputting the electric signal to an LIFI (Light Fidelity) transmitting control circuit; after processing the electric signal, driving the light emitting source to emit a light signal to the marker of the mobile terminal by the LIFI transmitting control circuit; alternately or simultaneously sending the light signal to a light signal receiving end through each character in the marker. According to the data transmission method provided by the embodiment of the invention, a data transmission channel based on a LIFI technology can be diversified.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data transmission method and a mobile terminal. Background technique [0002] As the functions of mobile terminals become more and more powerful, users' dependence on mobile terminals is gradually strengthened. With the frequent use of mobile terminals by users, the amount of user information stored in mobile terminals, such as graphics, videos, privacy and health data, is also increasing. For the increasingly large data, it takes a long time to transmit it, which is time-consuming and labor-intensive. [0003] At present, data transmission between mobile terminals mainly uses three methods: wired data transmission, wireless data transmission, and data transmission based on LIFI technology. [0004] Data transmission is based on LIFI technology, using fast light pulses to transmit information wirelessly. LIFI technology does not need a WiFi signal for data transmission...
