碩士 === 國立臺灣師範大學 === 機電科技學系 === 101 === This thesis is the design of a highly collimating optical film with microstructures on both sides in edge-type backlight module. The design can be used in tablet PCs, notebook computers, digital cameras ... etc. with small and medium-size LCD screen products. The concept is based on the inverse prism array brightness enhancement film, simulation results show that under the same light source, the peak intensity of the designed film is about twice the peak intensity of inverse prism film, and the energy utilization rate is about 98%. The designed highly collimating optical film can be manufactured by the self-alignment method, and the peak of the emitted light intensity can be found in the normal direction with the FWHM about 16 degrees. The Simulation results are similar to the measurement results, showing the reliability.
