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.

Abstract: The present invention provides a direct light backlight module with solar light assistance, which comprises a backboard. The backboard is provided with a waveguide. A light source is disposed under the waveguide. An optical film module is disposed above the waveguide and faces the light emitted from the direct light source. An assisting light source device is provided and which collects solar light and direct it to an optical film module. The present invention further provides a liquid crystal display device with the direct light backlight module with assisting solar light. With the provision of the assisting light source, the solar light can be used as an assisting light source making the backlight module and the liquid crystal display device made therefrom become more environmental friendly.
