碩士 === 國立中興大學 === 物理學系所 === 103 === The study on the development of the direct type backlight taste optimization, process technology of the light, thin, narrow, US design province and other issues do cause abnormal taste improvement, this third generation after Lens in the direct type backlight Light the bar, making the microstructure pattern Lens First use of injection molding will be distributed to the direct type backlight Light bar, with a simple structure to alter the optical effect of light intensity distribution, to achieve high uniformity, high luminance requirements. Optical cause for saving the subsequent direct type backlight module design time and cost required to taste takes exception, the complete direct type LED backlight design and test, to further reduce the thickness of the backlight module, designed to seek to reduce the thickness of the most perfect design results. In this study, the process aspect, mold injection Lens feasibility molding process adjustment, simulation from the front of the optics to exit the machine is set mold design, Lens molding process optimization, parameter selection after manufacturing segment of Lens, the successful production of a new Generation Lens, and the establishment of a complete micro structure molding process to confirm the feasibility of this process and have the ability to mass production technology of actual direct type backlight on Light bar.
