| Zusammenfassung: | An optical sheet with a cone array is designed, simulated, and fabricated in order to substitute
the dual crossed prism sheets in the edge-type LCD backlight. The optimum structure of cone
textures that is compatible with the dual crossed prism sheets was obtained by simulating the
backlight installed with the cone array optical sheet. A SU-8 photoresist films of thickness 30~50
μm were spin-coated on a polyethylene terephtalate film (PET), and the cone texture array was
formed by using the diffuse lithography that employed a photomask with circular patterns and
an optical diffuser. KCI Citation Count: 12 |
