Abstract
A light guiding system, an edge-type backlight module and a liquid crystal display are disclosed. The light guiding system includes an ambient light collection system facing toward ambient light for absorbing the ambient light, a plurality of light guiding devices, and a fluorescent film arranged between the light emitting ends and the light incident surface. Each of the plurality of light guiding devices includes a light emitting end and a light incident end. The light emitting ends are arranged close to a light incident surface of a light guiding plate, and the light incident ends are arranged close to the ambient light collection system. The absorbed ambient light enters the light incident ends and propagates toward the light emitting ends. By adopting the fluorescent film, the light beams from the light emitting ends are diffused such that brightness difference on the light incident surface is enhanced.
