发明名称 Projector of a rear projection type
摘要 A number of units of projectors of a rear projection type are assembled together, and one screen commonly used for the assembled screen units is attached to front portions of the screen units. Assemblies, each having the above construction, are assembled in longitudinal and lateral directions to form a picture, so that a margin in the middle of the screen can be eliminated or the number of margins can be significantly reduced.
