Title:
IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/033684
Kind Code:
A1
Abstract:
Provided are an image display device and an image display method capable of controlling moving image blurring occurring in the image display device by adding a shutter plate to the image display device. Provided also are a three-dimensional image display device and a three-dimensional image display method capable of, when observing with polarized glasses, controlling binocular crosstalk by additionally adding a polarization modulating plate and capable of watching a clear three-dimensional image display.
A shutter plate is disposed in front of or at the back of the image display surface, is divided into a plurality of regions, and is configured so as to be able to open and close individually on a per-region basis. The shutter plate is configured such that the displaying in an image display unit and the opening and closing of a shutter in the shutter plate are controlled to be synchronized with each other so that only the part of the shutter plate corresponding to the scanning position of modulation light is closed. Right and left eye images depending on the parallax for visually recognizing a three-dimensional image are alternately displayed, as frames, on the image display surface of the image display unit by the scanning of modulation light. An observing device is disposed on the observer side and has: a polarization modulating plate divided into a plurality of regions and capable of switching polarization states individually on a per-region basis; and an element that exclusively transmits polarized light between the polarization modulating plate and the observer, the polarized light being different between the left and right eyes. In the observing device, the polarization modulating plate is configured such that polarization is controlled to be synchronized so that the polarization states in the part of the polarization modulating plate corresponding to the scanning position of modulation light are alternately switched.
