REFLECTING MIRROR STRUCTURE OF PROJECTION TELEVISION

摘要

PURPOSE: A reflecting mirror structure of a projection television is provided to improve picture quality of an image projected on a screen and to simplify a process of fabricating a reflecting mirror. CONSTITUTION: A reflecting mirror of a projection television includes a trapezoid frame, a curvature part(31), a sliding part(39), and a fixing part(38). The cross section of the frame has a rectangular shape. The curvature part is formed at a portion coming into contact with a reflecting film(21). The sliding part is extended from the curvature part downward. The reflecting film freely slides the sliding part. The fixing part is extended from the sliding part downward. The reflecting film is fixed to the fixing part. The reflecting mirror further includes a rib that improves the strength of the frame.
