    Abstract: 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。
    ;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%).
