Patent number: 11735139Abstract: 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.Type: GrantFiled: October 29, 2021Date of Patent: August 22, 2023Assignee: AGC Inc.Inventors: Naruki Yamada, Yukihiro Tao, Yoshinori Iguchi, Osamu Iwata

Patent number: 11480864Abstract: 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?.Type: GrantFiled: April 23, 2021Date of Patent: October 25, 2022Assignee: AGC Inc.Inventors: Naruki Yamada, Yukihiro Tao

Patent number: 11106125Abstract: A transparent screen, wherein a direction normal to a reference surface is defined as a first direction, a direction which is perpendicular to the first direction and in which each reflective inclined surface extends as seen from the first direction is defined as a second direction, and a direction which is perpendicular to the first direction and the second direction and in which the reflective inclined surfaces are arranged side by side is defined as a third direction, and in at least a part of an image projection area, to which the image is projected, in a section perpendicular to the second direction, the reflective inclined surfaces are formed so that inclination angles of the reflective inclined surfaces, measured on a per-respective reflective inclined surface basis, decrease, in a stepwise manner or continuously, away from one end in the third direction toward another end in the third direction.Type: GrantFiled: April 1, 2020Date of Patent: August 31, 2021Assignee: AGC Inc.Inventors: Naruki Yamada, Yukihiro Tao, Tsuneo Ichimatsu, Yusuke Sato

Patent number: 10981358Abstract: A laminated glass has a vehicle exterior side glass plate; a vehicle interior side glass plate; and an intermediate film disposed between the vehicle exterior side glass plate and the vehicle interior side glass plate. The laminated glass includes a display area for reflecting a projected image projected from vehicle interior, to display information. In at least a part of the display area, a film is arranged between the vehicle exterior side glass plate and the vehicle interior side glass plate. The film is a main reflection surface for the projected image. The display area is offset from the edge of the film by 5 mm.Type: GrantFiled: March 29, 2019Date of Patent: April 20, 2021Assignee: AGC INC.Inventors: Shunsuke Sadakane, Yoshinori Iguchi, Naruki Yamada, Tokihiko Aoki
