Problems solved by technology

[0008] However, in the transmissive transparent screen 101, such as Figure 18 As shown, the light L1 of the scene on the side of the first surface A, the light L2 irradiated by the illumination 202 (or the sun) on the side of the second surface B, etc. are scattered in the light scattering layer 134, so the transmissive transparent screen 101 as a whole appears to appear white cloudy
Therefore, even in the state where the projector 200 is not projecting the video light L onto the transmissive transparent screen 101, there is a problem that it is difficult for the observer X to see through the scene on the other side of the transmissive transparent screen 101.
[0009] In addition, in the state where the image light L of the projector 200 is projected onto the transmissive transparent screen 101, unnecessary light scattering occurs in the light scattering layer 134, so there is a problem that the contrast of the image is lowered, and it is difficult for the observer X to recognize the image.

Embodiment approach

[0140] In addition, the first form of the screen of the present invention is a screen having a first surface, a second surface on the opposite side, and a light-scattering layer comprising a transparent resin and a light-scattering material. The light-scattering layer also contains a light-absorbing material, fog The intensity is 3-30%, the total light transmittance is 15-95%, and the diffuse reflectance is 0.1-2.4%. It is not limited to figure 1 screen 1. Below, the screen with figure 1 The same structural parts of the screen 1 are marked with the same symbols, and descriptions are omitted.

[0141] The first method of transmissive transparent screen is as image 3 As shown, a screen 1a in which a light scattering layer 34 is formed on the surface of the second transparent substrate 20 may be used. When the transparent resin 32 is a cured product of a curable resin, an uncured curable resin composition layer can be formed on one side of the second transparent substrate 2...

Abstract

The purpose of the present invention is to provide: a light-transmissive transparent screen which has an excellent see-through characteristic for a scene on the far side of a transparent screen as viewed from a viewer when no image light is projected from a projector, and which has an excellent visibility for an image displayed on the transparent screen as viewed from the viewer when the image light is projected from the projector; and an image displaying system and an image displaying method that utilize the light-transmissive transparent screen. A light-transmissive transparent screen (1) includes a first surface (A), a second surface (B) opposite to the first surface, and a light scattering layer (34) that contains a transparent resin (32) and a light scattering material (33). The light scattering layer (34) further contains a light absorbing material, has a haze of 3-30%, total light transmittance of 15-95%, and a diffusion reflection rate of 0.1-2.4%.

Description

technical field [0001] The present invention relates to a transmissive transparent screen for recognizably displaying image light projected by a projector as an image to an observer on the opposite side of the projector, and an image display system and image display method using the transmissive transparent screen. Background technique [0002] The following members have been proposed as transparent members used in showcases for merchandise and the like, display cases for works of art, etc., windows for buildings, showrooms, vehicles, etc., glass doors, and indoor transparent partitions. [0003] Observing from the observer side can see through the scene on the other side of the transparent member, and when conveying information such as descriptions of goods, various machine states, destination guidance information, and communication items to the observer, various Displaying the image light projected by the projector as an image in a recognizable manner to the observer when ...
