Abstract: |
A light guide late consists of two light incoming surfaces being two opposite surface of light guide plate, one light outgoing surface being adjacent to two light incoming surfaces on top surface of light guide plate and a reflection surface opposite to light outgoing surface and with several microstructure. It features that center between two said light incoming surfaces is used as symmetric axis to arrange said microstructure and their size and density is decreased gradually and symmetrically along direction from center to two light incoming surfaces. A back light module prepared by said light guide plate is also disclosed. |
