Abstract

The invention discloses a projection display device which comprises a projection hard curtain and a connecting piece. The projection hard curtain is detachably arranged on the connecting piece which is a folded piece structure. One side of the folded piece is provided with a plurality of through holes. The folded piece is fixed on a wall body through the through holes and screws. The cross section of the other side of the folded piece is an L-shaped groove. According to the projection display device, through the fixation of the connecting piece on the wall body, the embedding of an upper screen frame into the groove of the connecting piece and the connection mode of lapping the projection hard curtain and the connecting piece, the bearing weight of the connecting piece is raised, the thickness of a screen is increased by using the projection hard curtain, thus the deformation of a projection screen is prevented, the screen is smooth, and the installation is convenient.

Description

technical field [0001] The invention relates to the technical field of screen projection display, in particular to a large projection display device. Background technique [0002] At present, when installing hard projection screens, it is generally used to open "hanging holes" at the two or four corners of the screen, and hang them on the wall through screws, or add hanging hole parts behind the screen, and then hang them on the screws on the wall. For large front projection hard screens, the thickness of front projection hard screens is limited due to the large area of ​​the hanging holes and the small bearing capacity (thickness of projection hard screens over 80 inches: 1.8mm~2.0mm), resulting in uneven screens phenomenon, and the suspension is difficult. Contents of the invention [0003] Aiming at the above-mentioned problems existing in the existing large front projection hard screen, a projection display device aiming at simple installation and flat screen is provi...
