20090309958 | DISPLAY DEVICE - A display device provides first and second images. The display device includes a display panel having electro-optical elements, including a first element group with first-image display elements displaying the first image and a second element group with second-image display elements displaying the second image. A light advance control unit controls light emitted from the first element group to advance to a first area displaying the first image and controls light emitted from the second element group to advance to a different, second area displaying the second image. The first and second element groups are controlled such that a first period in which the first-image display elements are driven and at least a part of the second-image display elements is not driven and a second period in which the second-image display elements are driven and at least a part of the first-image display elements is not driven are repeated. | 12-17-2009 |
20110221716 | IMAGE DISPLAY APPARATUS - An image display apparatus including a first optical modulation device and a second optical modulation device configured to emit formed image lights, wherein in a first period in which the first optical modulation device is caused to form a first image light, and the second optical modulation device is caused to form a second image light, the first image light being caused to switch to a first polarized light, and the second image light is caused to switch to a second polarized light, while in a second period in which the first optical modulation device is caused to form the second image light, and the second optical modulation device is caused to form the first image light, the second image light being caused to switch to the second polarized light, and the first image light is caused to switch to the first polarized light. | 09-15-2011 |
20110228179 | IMAGE DISPLAY APPARATUS - An image display apparatus includes a first optical modulation device and a second optical modulation device configured to emit linearly polarized lights whose polarization directions are perpendicular to each other, first pixels and second pixels are arranged in each of the first optical modulation device and second optical modulation device, retardation layers are disposed on the light emission side of the first pixels or second pixels, the retardation layers configured to convert one linearly polarized light of the linearly polarized lights into the other linearly polarized light. Either arrangements of the first pixels and the second pixels or arrangements of the retardation layers is set so as to be the same in the first optical modulation device and the second optical modulation device, and the other is set so as to be the reverse in the first optical modulation device and the second optical modulation device. | 09-22-2011 |
20120062446 | VIDEO IMAGE VIEWING GLASSES AND IMAGE DISPLAY SYSTEM - A pair of video image viewing glasses comprising: a pair of image selection members each of which selects incident light and transmits the selected incident light; and a frame member in which the pair of image selection members are accommodated side by side. The pair of video image viewing glasses is used with or without another pair of glasses. The frame member includes: a locking portion via which the other pair of glasses locks the pair of video image viewing glasses when the pair of video image viewing glasses is worn over the other pair of glasses; and a nose pad provided to be positioned between the pair of image selection members. The nose pad is detachably attached to the frame member. | 03-15-2012 |
20120062806 | SHUTTER GLASSES AND IMAGE DISPLAY SYSTEM - A pair of shutter glasses comprises: a pair of shutter members each of which has the following states switchable from one to the other: an incident light transmitting state and an incident light blocking state; a frame member in which the pair of shutter members are accommodated; and a drive circuit and a drive power supply that drive the shutter members. The frame member includes: a rim to which the shutter members are attached; and a pair of temples each of which has one end connected to the rim. At least one of the drive circuit and the drive power supply is accommodated on the other end side of the temple. | 03-15-2012 |
