Abstract

The object of the present invention is to provide an image display method which is cheap and capable of improving the advertisement effect. The inventive image display method enables a image display screen to display image by projecting the projection light for image display. To reflect the projection light to the diffusing reflective part and project light to the injecting direction, a transmissive part in the injecting direction for transmission displays a first image capable of being identified from the injecting side by projecting front projection light on the diffusing reflective part of an integrally formed image display screen, and displays a second image capable of being identified from the back of the injecting side by projecting back projection light Lb on the diffusing transmissive part.

Description

technical field [0001] The present invention relates to an image display method and an image display system for displaying images by projecting projection light for image display. Background technique [0002] In recent years, an image display system including a projector device (projection device) and a screen (image display screen) has been widely used for watching movies at home, giving presentations, and the like. In this case, generally speaking, screens for projector devices can be broadly classified into two types: reflective and transmissive. Among them, the reflective screen is configured to display (imaging) the projection light projected by the projector device while diffusing to the incident side and displaying (imaging) the screen that can be viewed from the surface side (the incident side of the projected light). image. On the other hand, the transmissive screen is configured to display an image that can be viewed from the back side by diffusing the projected...
