Thus amount of its usage is large if the specific uniformity is requested in the large size LCD display. In this thesis, a crystalloid structure with cone-shape is developed to increase the FWHM angle to 160°.Its performance and optimized structure are investigated and validated with a optical design and simulation soft ware. For a 30” back light module, the amount of usage with this new type wide-angle LED is only 60% of that with the traditional type LED. 韓斌 2008 學位論文 ; thesis 63 zh-TW
