  • LIGHT GUIDE PLATE AND A METHOD OF MANUFACTURING THEREOF
    Publication number: 20110002143
    Abstract: A light guide plate (100) has an input face (11) to couple light (B0) emitted by a light source (50) into said light guide (100), and an out-coupling grating (30) to couple light (B2) out of said light guide (100). Said out-coupling grating (30) is substantially perpendicular to said input face (11). A rough cut side of a light guide (100) is processed by a heated surface processing member (701) to smooth out irregularities and/or to implement a further diffraction grating (12) on said input face (11). The efficiency of coupling light out of the light guide (100) may be substantially increased and/or stray light effects may be reduced.
