Multi-point touch light-resistant hard glass rear projection ink crystal screen

Abstract

The invention discloses a multi-point touch light-resistant hard glass rear-projection ink crystal screen, which relates to the technical field of screen equipment. The screen comprises an ink crystallayer, an optical structure base layer, an imaging layer and a hard base layer which are sequentially attached from front to back; the hard base layer is transparent, a light-transmitting circuit board is arranged in the hard base layer, and the light-transmitting circuit board is used for detecting the action that a user presses the ink crystal layer; the imaging layer is used for enabling projection equipment to project light to the imaging layer for imaging; the optical structure base layer comprises a linear grating base layer and a structure layer, the rear side surface of the linear grating base layer is attached to the imaging layer, and the structure layer comprises a plurality of convex structures horizontally arranged on the front side surface of the linear grating base layer; and a plurality of horizontal light absorption layers are sequentially arranged in the optical structure base layer at intervals from top to bottom. The multi-point touch light-resistant hard glass rear-projection ink crystal screen has the advantages of maximized light absorption area, good user experience and good imaging effect.

Description

technical field [0001] The invention relates to the technical field of screen equipment, in particular to a multi-touch anti-light hard glass rear projection ink crystal screen. Background technique [0002] Projection screens are widely used in daily life. They are mainly used in large conference rooms, command and control centers, training and education structures, conference rooms, exhibition halls, exhibition halls, airports, window displays, etc. Projection screens are usually divided into front projection Screens and rear projection screens, among them, front projection projection screens usually rely on the principle of reflection, and rear projection projection screens rely on the principle of transmission. Existing projection screens have a variety of structures, but in various light environments, especially in bright ambient light environments, the surface is projected by strong light, which can easily lead to unclear, uneven, glare, Severe white mist. As we all ...

Problems solved by technology

Existing projection screens have a variety of structures, but in various light environments, especially in bright ambient light environments, the surface is projected by strong light, which can easily lead to unclear, uneven, glare, Severe white mist

As we all know, if the imaging screen of the projection screen is white and foggy (white), the contrast and brightness of the screen will be greatly reduced, which will easily cause users to see clearly, and then lose its own display, demonstration or advertising effect
