Abstract

A large-screen autostereoscopic display enables life-size realistic communication. In this study, we propose the tiling of frameless multi-view display modules employing flat-panel displays. A flat-panel multi-view display and an imaging system with a magnification greater than one are combined to construct a multi-view display module with a frameless screen. The module screen consists of a lens and a vertical diffuser to generate viewpoints in the observation space and to increase the vertical viewing zone. When the modules are tiled, the screen lens should be appropriately shifted to produce a common viewing area for all modules. We designed and constructed the multi-view display modules, which have a screen size of 27.3 in. and a resolution of 320 × 200. The module depth was 1.5 m and the number of viewpoints was 144. The viewpoints were generated with a horizontal interval of 16 mm at a distance of 5.1 m from the screen. Four modules were constructed and aligned in the vertical direction to demonstrate a middle-size screen system. The tiled screen had a screen size of 62.4 in. (589 mm × 1,472 mm). The prototype system can display almost human-size objects.
