Problems solved by technology

However, the touch sensing precision of the infrared touch method is low, and the effect is not good. At the same time, the infrared touch frame is limited by the size of the infrared LED light, and the frame is thick and wide.
[0006] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] see image 3 , the present invention provides a front-throw short-focus projection screen with touch control, comprising an anti-scratch layer 1, a colored layer 2, a diffusion layer 3, a Fresnel lens layer 4, a reflective layer 5 and a light-absorbing layer 6 arranged in sequence , also including the touch structure.

[0025] Among them, the anti-scratch layer 1, the colored layer 2, the diffusion layer 3, the Fresnel lens layer 4, and the light-absorbing layer 5 are all consistent with the conventional Fresnel projection screen structure.

[0026] see figure 2 , the touch control struc...

Abstract

The invention relates to the technical field of short-focus projection, and provides a touch-controlled orthogonal short-focus projection screen, comprising a scratch-resistant layer, a coloring layer, a diffusion layer, a Fresnel lens layer, a reflective layer and a light-absorbing layer arranged in sequence, and also comprising a touch-controlled structure. The touch control structure comprisesan upper electrode layer, an insulating layer and a lower electrode layer arranged in sequence. Thus, the invention comprises a scratch resistant layer, a coloring layer, a diffusion layer, a Fresnellens layer, a reflective layer and a light absorbing layer, and also comprises a touch control structure. The touch control structure comprises an upper electrode layer, an insulating layer and a lower electrode layer arranged in sequence. By combining the touch control structure, the projection screen has the touch control function. Compared with the conventional infrared touch control technology, it has the advantages of high precision, fast response, and does not affect the border structure.

Description

technical field [0001] The invention relates to the technical field of short-focus projection, in particular to a front-projection short-focus projection screen with touch control. Background technique [0002] Most of the screens used by existing projectors are front-projection screens, that is, the projector is placed in front of the screen, and light is reflected to human eyes by means of the reflection function of the screen. There must be no obstructions between the projector and the screen, so the distance from the projector to the screen determines the footprint of the projection system. In order to reduce the occupied area, the current projection lenses are gradually transitioning to short-focus and ultra-short-focus lenses. [0003] Short throw front projection screens can be divided into soft screens and hard screens. The soft screen can be rolled, mainly black grid (or line grid) projection screen, the texture structure faces outward. The hard screen cannot be ...
