Title:
マルチビュー指向性ディスプレイ
Document Type and Number:
Japanese Patent JP4404311
Kind Code:
B2
Abstract:
A multiple view directional display, suitable for an autostereoscopic or dual view system, comprises a parallax optic 3, a pixellated image display layer 4 such as a liquid crystal display ( LCD) and an imaging means 29. Imaging means 29 may be an lenticular screen, formed from holographic optical elements, or any convergent diffractive or refractive microstructures, such as fresnel lenses. Imaging means or lenticular 29 forms an image 30 of the parallax optic 3 or the display layer 4. The image may be formed so that the separation S' between the image and either the display layer 4 or the parallax optic 3 is less than the separation S between the display layer 4 and parallax barrier, as shown in Figure 5. In a further embodiment the image separation S' may be greater than the parallax to display separation S, as shown in Figure 7(G). These different arrangements allow the angular separation between viewing windows 13, 14 to be increased or decreased. Alternatively, the image produced may have a pitch equal to that of the parallax barrier or display element. The device may comprise a substrate with parallax optic and lens array on either side.
