Abstract

The invention provides an orthographic projection screen and a production method of a screen body thereof. The orthographic projection screen comprises a screen body which comprises a flat curing force layer made of PET (polyethylene terephthalate), an inner arc structure layer, a projection paint layer, a lusterless paint layer and a light absorption layer, the light absorption layer is arranged at the back of the flat curing force layer, the inner arc structure layer is arranged in the front of the flat curing force layer, one side, back to the flat curing force layer, of the inner arc structure layer concaves to form an inner arc, the projection paint layer is arranged on the side, and the lusterless paint layer is arranged on the projection paint layer.

Description

technical field [0001] The invention relates to a front projection screen, in particular to a front projection screen device and a method for making the screen body. Background technique [0002] Orthographic projection generally refers to the general projection type in which a projector is set in front of the projection screen and the projection screen is used to reflect the projection. As long as you have a projector and a projection screen, you don't need other steps, and you can enjoy the fun of images very simply and conveniently. According to the image quality requirements, some environmental factors should also be taken into consideration, especially the effect of the dark room (no outsiders are allowed to enter). Usually used in conference rooms, research rooms, audio-visual classrooms, multimedia halls, etc. [0003] Depending on the material of the projection screen, its optical response is also different. There are diffuse projection screens (white plastic scree...
