Abstract: A surround-vision display system with a very high visual dynamic range is made possible by distributing a limited number of LED's on the inside of a drum and then spinning that drum around a user. The pixel information for each horizontal position in space is sent to each corresponding LED it visits that position. The LED's are arranged in a grid on a panel tile, and the panel tile is tilted slightly, e.g., at 1.1-degrees. The result is each panel tile presents a continuous vertical stripe in the picture frame as all its LED's are swept by in the drum motion. Several panel tiles stacked vertically inside the drum all contribute to the whole height of the picture frame, e.g., several feet. The entire inside circumference of the drum is populated with the LED panel tiles to keep frame refresh rates up to avoid flicker while keeping drum rotation speeds down to reasonable levels. Thus even though the LED's and drum are moving, the image projected appears to be relatively stationary.

Abstract: To change image quality in accordance with the image to be displayed, a color filter plate 3 is driven to sequentially split the white light incident on an A portion into red, blue, and green light beams to irradiate a liquid crystal panel, thus displaying a full-color image by a so-called field sequential scheme. In this case, if a sector region 4BG of an auxiliary filter plate 4 is always matched to the A portion (FIG. 2A), the quality of a full-color image is defined by the color filter plate 3, resulting in an increase in luminance. In contrast to this, when a red filter section 3R and auxiliary red filter section 4R are synchronously driven to be simultaneously irradiated with white light, the quality of a full-color image is defined by both the color filter plate 3 and the auxiliary red filter section 4R. As a consequence, an image with excellent color reproducibility is obtained.

Abstract: In a moving-film display device, each pixel includes a moving film electrode capable of bending and a counter electrode. The display color of each pixel is determined when the moving film electrode bends by a potential difference between the moving film electrode and the counter electrode. The moving film electrode is connected to a signal line via a TFT. The TFT is turned on/off by an address line. A controller keeps the TFT ON until the potential of the moving film electrode becomes substantially equal to a signal potential, and turns off the TFT before the moving film electrode comes closest to the counter electrode.

Abstract: A volumetric, 3-D image is produced by moving a small number of 1-dimensional light arrays such that virtually all points of a desired volume have at least one light pass through them within the refresh time of the human eye. The motion of the lights consists of two simultaneous motion cycles that are substantially orthogonal to each other, with one being faster than the other. Proper control of the lights thus allows images to be produced within the volume. Each light element may be composed of a collection of smaller, directional lights, each pointed in a different direction. In such case, the lights may be controlled in a manner that permits each viewer of the volumetric image to only see a variant of that image properly hidden-line removed for his or her particular viewpoint. The display can thus produce volumetric images appearing appropriately hidden-line removed from multiple viewpoints simultaneously.

A plurality of one-dimensional display devices is used, so that compared with conventional devices in which only a single one-dimensional display device is used, even if the rewrite speed (scanning speed) per one-dimensional display device is slow, good image quality free of flicker can be obtained. By further extending this in a configuration using a plurality of columnar display units, a single image can be divided into a plurality of images and displayed in a row on a screen.
