This is the ray of light incident on the wall of . Light #151. (5a
J has different incident angles with respect to the louver (7). A ray of light that enters the louver at an angle of incidence like (5) passes through the louver (7) and enters the enemy crystal panel, but a ray of light that enters at an angle of incidence like (5aJ) passes through the louver (7). (7), and does not enter the liquid crystal panel mountain.In other words, the louver (7) has the function of supplying only light within a certain range of incident angles to the enemy crystal panel mountain. , the transmission direction of light on the a-crystal panel mountain is limited to a certain range of vertical and horizontal angles, and the light (transmission/s
#) It is clear that the ratio will improve dramatically.
