Image display apparatus
An image display apparatus includes: a first light source; a second light source; a deflection unit for deflecting the light emitted from the first light source toward a viewing position of the first image and deflecting the light emitted from the second light source toward a viewing position of the second image; and a spatial light modulator that has a plurality of pixels each of which includes a plurality of subpixels, and modulates the light having passed through the deflection unit on the basis of a first image signal and a second image signal. Each of subpixels is formed in a shape where the length in the first direction, which is substantially parallel with the line connecting the viewing position of the first image to the viewing position of the second image, is longer than or equal to the length in the second direction orthogonal to the first direction.
1. An image display apparatus for displaying a first image and a second image alternately, comprising:
a first light source for emitting light for displaying the first image;
a second light source for emitting light for displaying the second image;
a deflection unit for deflecting the light emitted from the first light source toward a previously assumed viewing position of the first image and deflecting the light emitted from the second light source toward a previously assumed viewing position of the second image; and
a spatial light modulator including a plurality of pixels each of which includes a plurality of subpixels, and being configured to modulate the light having passed through the deflection unit based on a first image signal corresponding to the first image and a second image signal corresponding to the second image,
wherein each of the subpixels is formed in a shape in which a length in a first direction is longer than or equal to a length in a second direction orthogonal to the first direction, the first direction being substantially parallel with a line connecting a viewing position of the first image to a viewing position of the second image, and
wherein one of the pixels includes three of the subpixels, which are arranged in parallel with the second direction.
2. The image display apparatus according to claim 1 , wherein the length in the first direction of each of the subpixels is set at 43 μm or more.
3. An image display apparatus for displaying a first image and a second image alternately, comprising:
a first light source for emitting light for displaying the first image;
a second light source for emitting light for displaying the second image;
a deflection unit for deflecting the light emitted from the first light source toward a previously assumed viewing position of the first image and deflecting the light emitted from the second light source toward a previously assumed viewing position of the second image; and
a spatial light modulator including a plurality of pixels each of which includes a plurality, of subpixels, and being configured to modulate the light having passed through the deflection unit based on a first image signal corresponding to the first image and a second image signal corresponding to the second image,
wherein each of the subpixels is formed in a shape in which a length in a first direction is longer than or equal to a length in a second direction orthogonal to the first direction, the first direction being substantially parallel with an arrangement direction of the first light source and the second light source,
one of the pixels includes four of the subpixels, which are arranged in a 2×2 matrix, and
one of a right-eye image and a left-eye image is set as the first image and the other is set as the second image, the right-eye image and the left-eye image constituting a stereoscopic image,
the image display apparatus further comprises a third light source for emitting light for displaying one of the first image and the second image, and a fourth light source for emitting light for displaying the other image, and
the third light source and the fourth light source are arranged in a direction orthogonal to the arrangement direction of the first light source and the second light source.
4. The image display apparatus according to claim 3 , wherein the length in the first direction of each of the subpixels is set at 43 μm or more.
5. The image display apparatus according to claim 3 , further comprising a detection unit for detecting an attitude of the image display apparatus,
wherein, based on the attitude detected by the detection unit, the image display apparatus selects a light emission by the first light source and the second light source or a light emission by the third light source and the fourth light source.
