Abstract

An optical communication transmitting device, an optical communication receiving device, a method, and a system are provided. The optical communication transmitting device includes: a light-emitting display screen, a liquid crystal panel, and a control circuit; the liquid crystal panel is located at a light emission side of the light-emitting display screen; the control circuit is configured to generate, according to a presetting encoding rule, a driving voltage that controls liquid crystal molecules of the liquid crystal panel to be twisted, and the presetting encoding rule is related to a target deflection angle, wherein a polarized light beam emitted from the light-emitting display screen passes through the liquid crystal panel driven by the driving voltage, and then is deflected according to the target deflection angle, and then is transmitted to an optical communication receiving device.
