Problems solved by technology

However, in these methods, the occurrence of diffraction due to lamination of the anisotropic absorbing film, the decrease in transparency, and the increase in haze have caused the problems of decreased visibility.

Embodiment Construction

[0039] Embodiments of the present disclosure will be described below with reference to the drawings.

[0040] figure 1 It is a schematic diagram showing a configuration example of a display system in one embodiment. figure 1 The shown display system 100 implements dimming (image brightness adjustment) on the transparent display body 10 according to the brightness of the transparent display body 10 itself or the surroundings of the transparent display body 10, thereby suppressing the transflection (the suppression may also include eliminating ). For example, the display system 100 controls the luminance of the image displayed on the transparent display body 10 based on the brightness detected by at least one sensor so that the image displayed on the transparent display body 10 is visible from the observer A and invisible from the observer B.

[0041] It should be noted, figure 1 Although the case where the display system 100 is mounted on the vehicle 200 has been exemplified...

Abstract

A display system comprises a transparent display body having a first surface and a second surface on the opposite side to the first surface; a sensor for detecting the brightness of, or in a vicinity of, the transparent display body; a computing unit which, on the basis of the brightness detected by the sensor, derives a background luminance due to external light when the transparent display body is viewed from the second surface side; and a control device which causes an image to be displayed on the first surface. The control unit controls image luminance which is the luminance of the image being displayed on the first surface, in accordance with the background luminance derived by the computing unit, so that a ratio BB / SB becomes less than or equal to a predetermined contrast value, wherein BB is back-appearance luminance which is the luminance of the image produced on the second surface side, and SB is the background luminance.

Description

technical field [0001] The invention relates to a display system, a display method and a transparent display body. Background technique [0002] Conventionally, there has been known a system that has transparency to transmit background light and can visually recognize video light projected from a projector installed on the video display surface side as an image by an observer on the video display surface side. The displayed so-called reflective image display transparent member. Among them, the transparent screen can reflect the projected image light to display the image in the state of sticking or clamping to a member with high light transmission such as window glass or car windshield and fixed it. The view on the other side can also be seen through. Therefore, such transparent screens are in increasing demand for reasons such as high designability. [0003] However, when image light is obliquely projected on a reflective image display transparent member, a part of the im...
