Golden Tiao, deputy general director of the Electronics and Optoelectronics Research Laboratories at the Industrial Research Technology Institute (ITRI), explains that the active-shutter approach works by “ controlling time. ” Viewers wear glasses with liquid-crystal “ shuttered ” lenses that flip between transparent and opaque on alternate sides every 1 / 120th of a second. This results in each eye seeing a different image.
工研院電子與光電研究所副所長刁國棟解釋，「快門」式電視的原理在於「控制時間」，在以 1/120 秒為單位的短暫瞬間中，分別傳送給左右眼不同的畫面，觀眾再配合戴上可同步控制左右眼接收時間的快門眼鏡。
