A multi-touch anti-light hard glass rear projection smoky crystal screen

Abstract

The invention discloses a multi-touch anti-light hard glass rear-projection ink crystal screen, which relates to the technical field of screen equipment, and comprises a ink crystal layer, an optical structure base layer, an imaging layer and a hard base layer which are arranged sequentially from front to back ; Wherein, the hard base layer is transparent and has a light-transmitting circuit board inside, and the light-transmitting circuit board is used to detect the user's action of pressing the smoky crystal layer; the imaging layer is used to allow the projection device to project light onto it for imaging; the optical structure The base layer includes a line grating base layer and a structure layer. The rear side of the line grating base layer is bonded to the imaging layer. The structure layer includes a plurality of convex structures that are horizontally protruded on the front side of the line grating base layer; A plurality of horizontal light-absorbing layers. The invention has the advantages of maximizing the 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
