The present invention is directed to a rear projection display device so adapted as to receive a projected image from a light valve for image formation on the rear surface of a screen and emit image light toward an observer positioned on the front side of the screen, wherein the screen is formed in the shape of a concavely curved surface with respect to the observer, so that the observer can feel as if he or she was present more intensely.

Rear projection display device

The present invention relates to a method of converting two-dimensional images into three-dimensional images. In the present invention, a right eye image signal and a left eye image signal between which there is relatively a time difference or a luminance difference are produced from a two-dimensional image signal, thereby to convert two-dimensional images into three-dimensional images. According to the present invention, therefore, it is possible to convert the existing two-dimensional image software into pseudo three-dimensional image software to obtain three-dimensional images.

Display system with 2D/3D image conversion where left and right eye

The present invention provides a three-dimensional display comprising an LCD projector, a diffusing plate arranged on a surface on which an image projected by the LCD projector is formed, and a parallax barrier having slits in the shape of vertical stripes which is arranged on the side of a viewer with respect to the diffusing plate, wherein a lenticular lens plate is arranged on the side of the LCD projector with respect to the diffusing plate, and an image having black portions each having a larger rate of the width than that of a black matrix on the LCD projector is formed on the diffusing plate without decreasing brightness by the function of respective lenses constituting the lenticular lens plate, thereby to increase the ratio of each of the slits of the parallax barrier at which there is no crosstalk region.

Three-dimensional display

In a flat display having data-side address electrodes and scanning-side address electrodes arranged in the form of an XY matrix on the respective surfaces of a board, an apparatus for and a method of driving the electrodes by applying a horizontal scanning signal to the scanning-side electrodes successively, applying an image signal to every other data-side address electrode, applying a correction voltage signal of a specified fixed voltage value to the electrodes on opposite sides of each address electrode receiving the image signal, and alternately applying the image signal and the correction signal as replaced by each other to the data-side address electrodes for every scan.

Apparatus for and method of driving electrodes of flat display

A flat display includes a front panel having a fluorescent screen on its rear side, a rear panel defining a flat space with the front panel, linear filament cathodes arranged close to the rear panel, and an address electrode plate having a multiplicity of apertures and disposed close to the front panel. The rear panel is formed on its inner surface with spacer ridges each extending on each side of each filament cathode therealong and having a height to reach the address electrode plate. The spacer ridges give the flat display improved strength against pressure.
