Abstract

The invention provides a multichannel metameric visible light communication method and related products. A first group of multispectral channels is used to transmit communication signals; a second group of multispectral channels does not bear communication channels, and adjusts and presents light colors; the first group of multispectral channels comprises one or multiple multispectral channel channels; and the second group of multispectral channels comprises one or multiple multispectral channel channels. Stroboscopic and photochromic problems during multichannel signal transmission in relatively low frequency are solved.

Description

technical field [0001] The invention relates to the technical field of terminal equipment, in particular to a multi-channel metameric visible light communication method and related products. Background technique [0002] Visible light communication mainly realizes signal control by controlling the brightness and darkness of the light source, corresponding to 0 and 1 signals respectively, and its transmission rate is getting faster and faster. In the case of ultra-high-frequency changes, such as tens of thousands of times per second, or even millions of times, the human eye cannot perceive the change of light, and at the same time realizes the transmission of signals. However, if the light source changes at a relatively low speed, it is easy to observe the strobe of the light source, especially in the signal modulation, the light source is in two extreme states of bright and dark, which is easier to observe. In practical applications, there are many situations where there is...
