Abstract: A large format modular video display includes a plurality of video image units, each image unit sealed against environmental intrusions. Each image unit includes a housing having a front panel and a rear door panel that may be opened for access to the interior. Within the housing, a strongback member supports an LED circuit board having a large plurality of LEDs supported in pixel array, each pixel comprised of a plurality of LEDs of various colors. A gasket member is dimensioned to cover the pixel array of LEDs, and includes an array of LED holes in registration with the pixel array of the LED board, so that each LED extends through a respective hole in the gasket. The front panel of the housing also includes an array of LED holes in registration with the holes of the gasket member, so that each pixel group of LEDs may extend through respective holes in the front panel and protrude forwardly therefrom.

Abstract: A large format video display includes modular construction to permit the repair and exchange of single modules. Each module includes a pair of enantiomorphic side panels, each including top and bottom flanges and a rear flange extending inwardly. At the front end of each rectangular side panel, a plurality of formed bends define an integral rectangular column extending outwardly from the panel. A generally rectangular bottom tray includes a rear floor portion for supporting a video projector unit aimed toward the front of the module. A pair of ears extend outwardly from the front ends of the side panels, and are configured each to be engaged with the integral column of the respective adjacent side panel. The bottom tray is dimensioned to engage the bottom flanges of the side panels, so that the side panels support the weight of the bottom tray and the video processor.

Abstract: The present invention relates to a system for group viewing of kaleidoscopic images in which such system is a fully-integrated unit that is compact, attractive and of relatively low cost. In preferred form, the system uses a TEE-shaped outer housing in which system elements for the separate functions of cooling, for kaleidoscopically projection, for viewing and for angular pattern driving are accurately and compactly provided. The system elements that provide the functions of cooling, kaleidoscopic projection and viewing are positioned in first and second parallel arms (of circular cross section). While a third transverse arm (of square cross section attached to a flared base supported on a horizontal surface of a desk, table or the like, supports the angular driving elements.

Abstract: A multiple screen, modular video display system includes a plurality of video projection units joined together in a matrix to form a large video wall display. Each unit comprises a trio of CRT projection tubes providing RGB images directed to a screen assembly including a fresnel lens which collimates and projects the combined image orthogonally from the screen and eliminates the dark border areas between adjacent projection tubes. Disposed between the adjacent units are blinder panels which block leakage of light from one unit onto the image area of adjacent units, thus eliminating spillover of image portions in the matrix display. The projection units may be grouped in modules of four units each, connected by a common frame assembly which supports the units and the associated screen assembly.
