An image display device comprises an optical imaging arrangement for providing image information to illumination light and for transmitting the light as an optical image signal; a display for receiving the optical image signal and for displaying an image based on the image information; and a projecting optical arrangement including a reflecting part having a reflecting surface for reflecting the optical image signal, and a refracting optical part having a refracting surface for projecting the op...

A digital projector for providing digital images for display to a user, the digital projector comprises a housing having its vertical dimension substantially greater than its horizontal dimension; a light source enclosed within the housing for providing light; a digital imager through which the light of the light source is projected for providing digital images for display to the user; a single mirror for reflecting the digital image from the digital imager; and a lens for receiving the digital ...

A liquid crystal display with projecting function including an open-top box body with enclosed sides, a projection light source, a condensing lens, a liquid crystal display plate, a relay plate, a reflective lens and a back light plate. The projection light source is disposed at the bottom side of the box body. The condensing lens is disposed in the box body above the projection light source. The liquid crystal display plate has one side connected to a display light source and the other side con...

Projection display device which comprises a light source for generating a light beam, integrator means for converting the light beam into a uniform rectangular beam, modulator means for modulating the rectangular light beam with the information to be displayed, and projection means for projecting the modulated rectangular light beam on a display plane. The integrator means comprises a triangular prism and an integrator device positioned between the light source and the triangular prism. The tria...

A device for producing esthetically pleasing patterns of light which is controllable like a musical instrument. The device includes an elastically stretchable reflective mirror surface which is spaced from a high intensity light source. A collimating and focusing lens is interposed between the reflective surface and the light source so that light beams emanating from said light source and reflected from said reflective surface are focused st a point within an aperture defined in the cabinet of t...

A video projection system has an image deflection device to provide additional mounting options for a projector. The deflection device selectively positions a mirror in front of the projection lens to deflect the video image away from the optical axis of the lens, thereby allowing the projector to be mounted without the lens facing the projection surface. The projector includes an image processor for selectively flipping the video image to accommodate a first mounting configuration in which the ...

In a system of overhead projection there is provided a horizontal stage on which is to be placed an object to be imaged. Means for illuminating the object is mounted below the stage at an angle thereto, while a projection lens system is installed above the stage and parallel thereto, in such a position that the axis of the light from the illumination means passes at an angle through its center. A mirror mounted above the lens system projects the undistorted image of the object onto a vertical sc...

A projection apparatus includes a light source having a light emitting portion having a finite size, a concave reflecting mirror for condensing light from the light source, a condenser lens unit for converting the beam of light from the concave reflecting mirror into a substantially collimated beam of light, a light valve for reflecting the beam of light from the condenser lens unit and spatially modulating the beam of light on the basis of predetermined image information, and a projection optic...

In an image forming apparatus, a brush member is formed from a brush made from acrylic resin that has not been subjected to conductivity-enhancing processes. The brush member is attached to a conductive plate. A resistor is provided in series with the conductive plate and a fixed power source. The fixed power source applies a predetermined high voltage to the conductive plate.

A reflecting film is made by forming resin layers on both sides of a metal thin film, and using a colorless, transparent, and optically isotropic material at least in one resin layer. A reflecting film is made by forming a metal thin film on one side of a resin film, and forming a colorless, transparent, and optically isotropic resin coat layer on its surface by printing or other method. A mirror having such a reflecting film is mounted on a frame. A projection type image magnifying apparatus fo...
