摘要(中)

本論文研究使用光柵來進行分光，當包含藍、綠、紅光波長的白光經過光柵後，因波長影響繞射角度而分離藍光、綠光和紅光，並在透鏡微結構焦在一個畫素中相對於彩色濾光片藍、綠、紅光的位置。
利用雙面光柵的設計提升藍、綠、紅光波長的繞射角度差，也兼顧了最大穿透繞射階的效率，透鏡微結構分光設計使最大穿透繞射階的效率和次大穿透繞射階的效率重疊在一個畫素中藍、綠、紅光的位置。在使用理想光源時，在色域圖上面積可以達到NTSC的73%；能量利用率上，藍光61.45%、綠光67.52%、紅光60.91%，各色都比只使用彩色濾光片而未使用光柵分光的26.67%高。在考慮實際背光的角度下，在色域圖上面積只有NTSC的18%；能量利用率上，藍光42.87%、綠光54%、紅光43.25%，各色也是都比只使用彩色濾光片而未使用光柵分光的26.67%高。

摘要(英)

This study use grating which includes blue, green and red ray to split the rays. Due to the wavelength difference, different rays can be separated. Then the rays after the microstructure lens focus on the blue, green and red positions of the color filters.
We use double-sides grating to enhance the blue, green, and red wavelength of their diffraction angle and take into account the maximum penetration diffraction efficiency. Microstructure lens let the maximum penetration of the diffraction efficiency and the second largest penetration efficiency superimpose in the same position of the pixel. When using the ideal light source, the color diagram area can reach 73% NTSC; and on energy efficiency, blue ray is 61.45 %, green ray is 67.52 % and red ray is 60.91 %. They are higher than using only color filters but not using grating (26%). In consideration of the actual angle of the backlight, the color map area is only 18% of NTSC; on energy efficiency, 42.87% blue, green 54% and red 43.25%. They are higher than using only color filters but not using grating (26%).
