Abstract: A handheld terminal, a computer and a visible light communication system are disclosed. In the handheld terminal, a first backlight apparatus is disposed on a display screen of the handheld terminal, a first data processing apparatus accesses data from a first data storage apparatus and converts the data to multiple luminance level control signals that are used to control the luminance level of the first backlight apparatus, a first control apparatus controls the first backlight apparatus to adjust its current luminance based on the multiple luminance level control signals, and the first backlight apparatus changes its luminance in accordance with the change of the data and, as a result, transmits the data to the computer in the form of visible light. Thus, the present disclosure eliminates the need of cumbersome physical connection ports and intermediate connection cables, and enables stable, reliable and highly secure visible light communications.
