A display construction comprising first and second display panels of light-weight sheet material, each divided into a plurality of vertical planar sections by vertical folds. The top and bottom edges of each panel form a zig-zag pattern that enables the bottom panel to be supported on a flat supporting surface and the second panel supported on the first panel, the lower portions of individual sections of the second panel intersecting the upper portions of individual sections of the first panel.

A liquid crystal display apparatus comprises a first and second housing portions. The first and second housing portions are coupled so that the angle of the opposing surfaces may be adjustable. A light transmitting portion is formed on the upper surface of the first housing portion. The light beam received by the light transmitting portion is further transmitted through a liquid crystal plate and a colored filter housed in the first housing portion and then is led to impinge upon the mirror prov...

A magnet operated display or indicator device selectably displays one of two faces of a disk. The disk is stopped in each limiting position by a stop contacting the disk inboard of its edge to another aspect the magnet is offset relative to the pivot axis of the disc to give better starting torques. In another aspect, where a plurality of disks are in columns, the pivot axes are stepped to be parallel but not coaxial.

A display device having a plurality of information symbols for each light source such as an LED chip. The upper surface of each LED chip is divided into several light-emitting areas by a patterned array of electrically isolated, spaced electrodes. The LED chips are mounted to a substrate and can be selectively activated by a beam lead tape, which is also mounted to the substrate. A cover for the display forms thin, reflective light channels, each of which extends laterally from a light-emitting ...

A point-of-sale display device including two parallel panels which are pivotally operated to display advertising indicia and the like provided on each of the opposite sides thereof, said panels being proportioned to overlap to close a window in the display and when so overlapped, the advertising indicia on each of the respective panels is positioned to form a complete message.

A display for displaying variable and permanent data. It has two support plates 1 and 2 which form between themselves a chamber 3 in which a fluid which can be switched between optically different states is arranged. Polarizers are arranged on the sides of the support plates 1 and 2 which face away from the chamber 3. In the region of permanent data, transparent elements 14 are present between the support plates 1 and 2. Furthermore, a source of light 15 is arranged on the side of the cell facin...

A display assembly 10 is adapted to selectively illuminate those numerals associated with a home address. Moreover, display 10 includes a mounting member 12 which is adapted to be mounted to the surface of the house and a flat plate 26 which is adapted to overlay the mounting member 12 and which further is adapted to receivably mount neon tubes 30 which are selectively illuminated and which are configured in a shape which is substantially similar to numerals associated with a home address.

A display comprises a static unit (8) on which is mounted a rotating unit (7) driven by a motor (12). The rotating unit carries light emitting diodes (6) arranged as vertical columns which sweep around a cylindrical surface. The light emitting diodes (6) are controlled by a control circuit (6) in accordance with data stored in a memory (61) so as to provide a cylindrical display. The control circuit (60) and memory (61) are located in the rotating unit 97) and the memory (612) has a capacity for...

The present invention provides for a field emission device including an anode assembly and a cathode assembly, wherein the cathode assembly further includes a substrate, a plurality of electrically conducting strips deposited on the substrate, and a continuous layer of diamond material deposited over the plurality of electrically conducting strips and portions of the substrate exposed between the plurality of electrically conducting strips. The field emission device may further include a grid as...

A stereoscopic 3D display comprises a light source and condenser optics which direct light through a spatial light modulator and a polarisation modulator. Each of the modulators is pixellated with the pixels of one modulator being optically aligned with respective pixels of the other modulator. Each pixel of the spatial light modulator is controlled so as to provide a light amplitude which is equal to the square root of the sum of the squares of the corresponding pixels of the stereoscopic image...
