Abstract: There is provided a transparent screen which is capable of separating a direction where a hot spot is observed and a direction where a bright video is allowed to be observed, and establishing a direction where a video is allowed to be wholly brightly observed.
A transparent screen includes a first transparent layer, a reflective layer reflecting projected video light, a second transparent layer disposed opposite to the first transparent layer with respect to the reflective layer so as to make a background visible therethrough; wherein the reflective layer has a plurality of slant reflective surfaces, each of the slant reflective surfaces being slant to a reference surface that is a surface of the first transparent layer opposite to the reflective layer; wherein each of the slant reflective surfaces is provided with a concavo-convex and is formed in a stripe shape when seen from a normal direction of the reference surface; and wherein the slant reflective surfaces are disposed so as to have angles to the reference surface, the angle changing with random variations in of range with respect to a certain central angle.-

Abstract: A transparent screen includes a plurality of transparent plates arranged in a front-rear direction; and a screen main body, interposed between the transparent plates, configured to display video images projected from a front side or a rear side of the transparent screen to a user on the front side, and enable a rear background to be visually recognized by the user. In a cross section orthogonal to a part of an outer edge of the transparent screen, the transparent screen has a curved shape, and a length of a center line in a plate thickness direction of the transparent plate on an external side of the screen main body in a curvature radius direction of the curved shape is greater than a length of a center line of the transparent plate on an internal side of the screen main body.

Abstract: The visibility of the external scene from the inside of the transmissive transparent screen when the video image is not displayed and the visibility of the video image from the outside when the video image is displayed are satisfied.
In a video image display system comprising a projection device 100 and a transmissive transparent screen 1 having a first surface and a second surface on the opposite side of the first surface, having a visible light transmittance of at least 5[%], and displaying video images projected from the projection device 100 installed on the first surface side, as video images visible to an observer on the second surface side, the following formula 1 is satisfied:
−1.5≤ln(((B/A)/I)×G)≤3.9 Formula 1
in the formula 1, A is the projection area [m2] of the projection device 100, B is the luminous flux [lm] projected onto A by the projection device 100, I is the ambient illuminance [lx] at the side of the second surface, and G is the screen gain of the transparent screen 1.-

Abstract: A display-system includes a transparent-display-body having a first-surface and a second-surface opposite to the first-surface, a sensor to detect a brightness of the transparent-display-body or a brightness around the transparent-display-body, an arithmetic-unit configured to derive, based on the brightness detected by the sensor, a background luminance caused by outside-light as when the transparent-display-body is viewed from a side of the second-surface, and a controller to cause video to be displayed on the first-surface, wherein where rear-show-through-luminance that is a luminance of the video that occurs on the side of the second-surface is denoted as BB and the background luminance is denoted as SB, the controller controls a video luminance in accordance with the background luminance derived by the arithmetic-unit such that (BB/SB) is less than or equal to a predetermined-contrast-value, the video luminance being a luminance at which the video is to be displayed on the first-surface.

Abstract: A reflective transparent screen exhibiting high brightness over a wide region in the screen although with a narrow viewing angle, and an image display system is provided. The reflective transparent screen has a first transparent layer 32 having an irregular surface, a reflective layer 40 formed on the irregular surface, and a second transparent layer 52 formed on the irregular surface on which the reflective layer 40 is formed so as to fill irregularities. The irregular surface of the first transparent layer 32 has a slant angle in a first direction being within a range of from −44′ to +44′, and a slant angle in a second direction perpendicular to the first direction being within a range of from −44′ to +44′.

Abstract: A transparent screen sheet that displays images projected from a front side of the transparent screen sheet and/or a rear side of the transparent screen sheet to a user on the front side, and causes the user on the front side to view a rear background behind the rear side. The transparent screen sheet includes an image display layer configured to display the images; and a resin film that holds the image display layer. A difference between a maximum value and a minimum value of retardations of the resin film measured by irradiating a main surface of the resin film with a light with a wavelength of 460 nm in a direction orthogonal to the main surface, within a region on the main surface that overlaps with the image display layer, is one fourth of the wavelength of the light or less.
