Viewing Angle Switchable Display with a Compact and Directional Backlight Module
A compact light guide plate (LGP) with special designed microstructures and dual collimated light sources was proposed to achieve an adjustable viewing angle backlight for eco-display. The micro-prisms were utilized to guide the emitting rays toward normal viewing cones while a set of strip patterned diffuser toward wide viewing cones. The uniformity of spatial luminous can reach 91% / 87% at v...
متن کاملViewing zone of an autostereoscopic display with a directional backlight using a convex lens array
When a directional backlight to each eye alternates synchronously with the alternation of left-eye and right-eye images on the display panel, the viewer can see a stereoscopic image without wearing special goggles. One way to realize a directional backlight is to place a convex lens array in front of dot matrix light sources to generate collimated light. To implement this method, however, defoc...
متن کامل34 . 2 : Multiple - Viewing - Angle Projection - Display Technique for Videoconferencing
We have developed a technique that changes the image seen on a screen depending on the viewing angle. A new display apparatus for video conferences based on this technique projects multiple images of participants taken from different angles onto a directional screen consisting of a directional diffusion plate and lens. This display apparatus provides us with the natural feeling and comfort of d...
متن کاملNumerical investigation on the viewing angle of a lenticular three-dimensional display with a triplet lens array.
We investigate the viewing angle enhancement of a lenticular three-dimensional (3D) display with a triplet lens array. The theoretical limitations of the viewing angle and view number of the lenticular 3D display with the triplet lens array are analyzed numerically. For this, the genetic-algorithm-based design method of the triplet lens is developed. We show that a lenticular 3D display with vi...
متن کاملSwitchable telescopic contact lens.
We present design and first demonstration of optics for a telescopic contact lens with independent optical paths for switching between normal and magnified vision. The magnified optical path incorporates a telescopic arrangement of positive and negative annular concentric reflectors to achieve 2.8 x magnification on the eye, while light passing through a central clear aperture provides unmagnif...
