Title:
THREE-DIMENSIONAL IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/064353
Kind Code:
A1
Abstract:
The purpose of the invention is to obtain not three-dimensional views utilizing human parallactic angles but three-dimensional views that can be naturally seen by means of a simpler device and further not only for a person who is just in front of a lenticular lens but also for a person who is not just in front thereof. Provided, as a solution, is a three-dimensional image display device that satisfies conditions a and further b and/or c that follow. Condition a: Colors can change once or more times in a range that for a measurement result in HSB system of captured images obtained by successively capturing an image, which is not a moire pattern of a display surface, per 1/1000 second, one or more average values of H, S and B for 5/1000 seconds to 9/1000 seconds within a time period of 30/1000 seconds are 30 to 330 of H, 10 to 90 of S and 10 to 90 of B (where S and B are represented by values in a range of 0 to 100 percent) in relation to the respective immediately-preceding average values of H, S and B for 5/1000 seconds to 9/1000 seconds. Condition b: An optical member layer is further provided on the image display surface and when a laser light is irradiated onto the optical member layer at an incident angle of 60 degrees, the reflected light or transmitted light of the laser light diffuses to a plurality of points. Condition c: The display surface of the display device is made of liquid crystal and there is an image projection-use projector that utilizes the outermost surface of the display surface as a plane of projection.
