| Zusammenfassung: | The present invention relates to a total reflection pattern light guide plate for the use of front and back light sources, mainly by letting the cross section of the pattern be stage-like with an angle of elevation to increases the optical efficiency, and the bottom and side wall of the pattern with stage-like cross section are mirror surfaces which can reflect light completely, so that it is suitable for the use of front and back light source of light guide plate. By the innovation of different directions of light sources with the same designing method, the manufacturing costs can be reduced and the efficiency can be enhanced. |
