  • Backlight module with diffusing particles and prism refractive structure
    Patent number: 7954989
    Abstract: A backlight module includes a frame, a diffuser, a first light source, and a light guiding plate. The diffuser is disposed in the frame. A plurality of diffusing particles is doped into the diffuser. The refractive index of the plurality of diffusing particles is less than that of the diffuser. Furthermore, the diffuser has a first light entrance surface and a light exit surface. The first light source is disposed in a long-axial direction of the diffuser and is located at a side of the first light entrance surface. The light guide plate is disposed at a side of the light exit surface.
