Since only a single projector is used, the image resolution is limited. Therefore these devices are normally not found in image sizes larger than 120 to 150 inches.
18.104.22.168 Cube Display Wall
Due to its design, the cube display wall is by far the most common projection display type. Based on standard elements, a display with any size and requirement can be established, simply by tiling the required number of cubes. The cube consists of a metal enclosure and the front surface is the screen. Mounted inside are the projector and mirror. The screen and projection engine are tailor-made to match each other with the aim of achieving crisp, high-resolution, high-contrast images with a minimum of build-in depth. The mechanics of the cube are designed to allow the cubes to be placed very close to each other to minimise the physical gap between adjacent screens. These cubes can be built up to a matrix of different displays to produce a homogenous display wall (Figure 4.21 through Figure 4.24).
