| Abstract: | A new type of light guide plate with sub-micron gratings is proposed.By using rigorous coupled-wave theory,the relationship between the first order transmission efficiency and the depth of grooves is analyzed when lights transmit from sub-micron gratings' optically denser medium to optically thinner medium.The character of transmission field using red light(700mn),blue light(555nm),and green light(465nm) with incidence angle under total internal reflection condition is discussed.The relationship curve of the first order transmission efficiency versus depths of grooves is proved experimentally.Finally,the initial structure of light guide plate with sub-micron gratings is given and the error is analyzed. |
