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 to absorb the ambient light and to generate absorbed light, a plurality of light guiding devices, and at least a first and a second light guiding bar. Each of the light guiding devices includes a light emitting end and a light incident end. The light incident ends of the optical fibers are arranged close to the ambient light collection system, and the lights entered from the light incident ends are propagated toward the light emitting ends. Each of the light guiding bars includes a light emitting surface, a light incident surface connected to the light emitting surface, and a first lateral side opposite to the light incident surface.
