Problems solved by technology

This fixing method is prone to bumps and bulges in low-pressure areas, which makes the projection display screen uneven and affects the viewing effect. At the same time, the use of two layers of foam glue increases the thickness of the projection display screen, which is beneficial to the realization of Ultra-thin projection display screen is restricted

Abstract

The invention provides a projection displaying screen, and belongs to the technical field of projection displaying. The projection displaying screen comprises an optic mask, a backboard structure, andmagnetic stripes, wherein the backboard structure faces exactly the optic mask, the magnetic stripes are arranged between the optic mask and the backboard structure, are in magnetic attraction with the backboard, and are connected with the optic mask through double-sided foaming glue. The projection display screen can have good flatness, the bad phenomena of distortion, displacement, bending, protrusion, sinking, swelling and the like are avoided, and the watching effect of a user is improved; meanwhile, the thickness of the projection display screen can be reduced, and the ultrathin requirement of the user is met.

Description

technical field [0001] The present disclosure belongs to the technical field of projection display, and in particular, relates to a projection display screen and a projection display system. Background technique [0002] At present, the optical screens used in the market are mainly divided into hard screens and soft screens. The fixing method of the soft curtain is mainly to use elastic objects such as springs and elastic ropes to make the curtain form a plane and fix it on the surrounding frame. The fixing method of the hard curtain is mainly to paste the optical curtain on the surface of a rigid object (such as honeycomb aluminum plate, aluminum-plastic plate, steel plate, etc.), and then assemble a frame around the rigid object for covering and decoration. Projection products have high requirements on the flatness and light resistance of the screen. Due to the poor light resistance of the soft screen itself and its fixing method, it is difficult to meet the flatness requ...
