Abstract: An improved structure of a LCD screen lightguide panel comprises an arc inlaid groove sunken in the lightguide panel to be in accordance with the outer diameter of the light source tube and set in the lower edge of a wedge-shaped or rectangular lead-light panel. The inlaid groove is used for inlaying the cooperated light source tube and fastening it in position. The way of light emitting from the circumference of the light source tube can be into the lightguide panel by direct transmission, reflection and reflection that achieves the improved device of the highlight flux.

Abstract: An improved structure of a diffusing film and prism film in LCD screen mainly relates to using general optical fiber array to substitute for the structure of a diffusing film and prism film. This general optical fiber array is combined with the plural of short general optical fibers to be slices in an identical direction. In addition, the substitutes also can be the optical micro-fiber arrays formed by optical micro-fibers.

Abstract: An improved structure of heat sink is combined with the base and the structure of closed pipeline. By way of the cooling effect produced when solution in the pipeline of the structure of closed mini pipeline inside the base circulate and change mutually in the liquid state and steam, which makes some machine elements in machinery or electronic products running to cause waste heat cooling.
