Problems solved by technology

Here, a visibility region, which would typically be rather large, is limited to the locally positioned virtual observer windows.
One problem with autostereoscopically generated three dimensional images is that typically the viewer perceives the image to be inside the display, whereas the viewer's eyes tend to focus on the surface of the display.
This disparity between where the viewer's eyes focus and the perceived position of the three dimensional image leads to viewer discomfort after some time in many cases.

Embodiment Construction

A. Hologram Display with Calculation on the Same Substrate as the Pixels

[0118]An implementation includes a display which receives real space image data, such as an intensity map and a depth map corresponding to a three dimensional image. The holographic encoding of the spatial light modulator is then calculated in real time or in quasi real time based on the three dimensional image data. At least some of the hologram calculations may be performed in the physical space in which the pixel matrix exists, by combining two functional units, namely the hologram calculation unit and the hologram display unit, which are separate functionally and spatially in prior art devices, so as to form a common unit which is implemented on one substrate. This means that transistors for at least some of the hologram calculation may be integrated between, or next to, the transistors used for pixel control. Alternatively, all the hologram calculations may be performed in the physical space in which the pi...

Abstract

Disclosed is a high resolution display on which decompressed high resolution image data is displayed, the display including pixels, the pixels being on a substrate, where circuitry is present on the same substrate as the pixels, where compressed high resolution image data which has been compressed using known data compression techniques is received by the circuitry, the circuitry being operable to perform decompression calculations which provide subsequent display of decompressed high resolution image data by the pixels of the display.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a high resolution display device on which decompressed high resolution image data is displayed, the display including pixels, and the pixels being on a substrate. The high resolution display device may display normal image data. The high resolution display device may be one on which holographic display data is displayed.[0003]2. Technical Background[0004]Computer-generated video holograms (CGHs) are encoded in one or more spatial light modulators (SLMs); the SLMs may include electrically or optically controllable cells. The cells modulate the amplitude and / or phase of light by encoding hologram values corresponding to a video-hologram. The CGH may be calculated e.g. by coherent ray tracing, by simulating the interference between light reflected by the scene and a reference wave, or by Fourier or Fresnel transforms. An ideal SLM would be capable of representing arbitrary complex-valued numbers, i...
