Embodiment 1

[0021] The technical task of the present invention is achieved in the following manner, a method based on visible light communication, the method steps are as follows:

[0022] In the first step, the visible light communication sending module in the host sends a signal, and the visible light communication receiving module in the display device receives the signal;

[0023] In the second step, the data conversion module converts the visible light communication signal into the control signal of the display screen;

[0024] In the third step, the display control circuit receives the control signal and directly drives the display screen to display information.

[0025] Further, the specific sending steps of the visible light communication sending module are as follows: first, the sending end encodes the sending data through the encoding unit, then sends the encoded signal to the LED through the LED driving circuit, and finally ensures the sending of the optical signal through the ...

Abstract

The invention discloses a visible light-based communication method and display equipment thereof. The display equipment structurally comprises a visible light communication module, a data conversion module, a display control circuit and a display screen; a visible light communication receiving module is integrated in the display equipment; data interaction between the display equipment and master equipment integrated with a visible light communication sending module is carried out; information sent by the master equipment, such as a computer and a server, is read, decoded and displayed in a visible light communication manner; physical connection between the display equipment and the master equipment is unnecessary; and thus, the operation flexibility and convenience are improved.

Description

technical field [0001] The present invention relates to the technical field of visible communication, in particular to a method based on visible light communication and a display device thereof. Background technique [0002] Traditional display devices use physical media connection methods such as plug-in or VGA cables to complete the connection between the main device and the display device, and then realize the design of data reading and writing. VGA (Video Graphics Array) is a video transmission standard introduced by IBM together with PS / 2 machine in 1987. It has the advantages of high resolution, fast display speed and rich colors, and has been widely used in the field of color displays. Does not support hot plugging, does not support audio transmission. [0003] Visible Light Communication technology (Visible Light Communication, VLC) refers to the use of light in the visible light band as an information carrier, without using optical fiber and other wired channel tra...
