Title (EN) OPTICAL DEVICE AND DISPLAY OPERATING IN TWO DIMENSIONAL AND AUTOSTEREOSCOPIC THREE DIMENSIONAL MODES
(FR) DISPOSITIF OPTIQUE ET AFFICHAGE FONCTIONNANT EN MODE 2D ET EN MODE 3D AUTOSTEREOSCOPIQUE
Abstract: front page image
(EN)An optical device comprises an input polariser 4, a patterned retarder 5 and an output polariser 12. The retarder 5 has regions 8 and 9, at least one of which alters the polarisation of light from the input polariser 4. The output polariser 7 has a transmission axis 12 such that light passing through the regions 8 and 9 of the retarder 5 and through the output polariser 7 is matched in amplitude, phase and polarisation. Such a device may be used as a switchable parallax barrier with an LCD 2 to provide a display which is switchable between an autostereoscopic 3D mode and a 2D mode with the 2D mode having more uniform intensity across the display.
(FR)L'invention concerne un dispositif optique comprenant un polariseur d'entrée (4), un retardateur à motifs (5) et un polariseur de sortie (12). Le retardateur (5) comporte des zones (8, 9) dont au moins une modifie la polarisation de la lumière provenant du polariseur d'entrée (4). Le polariseur de sortie (7) comporte un axe de transmission (12) de façon que la lumière traversant les zones (8, 9) du retardateur (5) et le polariseur de sortie (7) soit d'amplitude, de phase et de polarisation égales. Ce dispositif peut être utilisé comme barrière parallaxe commutable avec un écran à cristaux liquides (2) pour obtenir un affichage pouvant passer d'un mode 3D autostéréoscopique à un mode 2D, offrant une intensité d'affichage plus uniforme.
