Abstract:
(EN) The present application relates to an optical film, an optical element, and an imaging device. The optical film of the present application not only exhibits broadband polarization conversion characteristics in the visible light wavelength range, but also has an absorption band in the visible light wavelength range. Such an optical film can be employed as an optical element, such as a diffraction light-guide plate laminate, in an imaging device, such as an augmented reality device, so as to suppress crosstalk.
(FR) La présente invention concerne une composition adhésive, un film protecteur, un élément optique et un dispositif d'affichage. Le film optique de la présente invention présente non seulement des caractéristiques de conversion de polarisation à large bande dans la plage de longueurs d'onde de lumière visible, mais a également une bande d'absorption dans la plage de longueurs d'onde de lumière visible. Un tel film optique peut être utilisé comme élément optique, tel qu'un stratifié de plaque de guidage de lumière de diffraction, dans un dispositif d'imagerie, tel qu'un dispositif de réalité augmentée, de façon à supprimer la diaphonie.
(KO) 본 출원은 광학 필름, 광학 소자 및 영상 장치에 관한 것이다. 본 출원의 광학 필름은 가시광선 영역에서 광대역 편광 변환 특성을 나타낼 뿐만 아니라, 가시광선 영역에서 흡수 밴드를 가진다. 이러한 광학 필름은 증강 현실 기기 등의 영상 장치에 회절 도광판 적층체와 같은 광학 소자로 적용되어 크로스토크를 억제할 수 있다.
