Display apparatus and electronic apparatus
View Patent ↗A display apparatus allowing a user positioned in a first direction to visually recognize a first image and allowing a user positioned in a second direction different from the first direction to visually recognize a second image includes: a display unit displaying a combined image formed by combining the first image with the second image; an irradiation unit irradiating the display unit displaying the combined image with irradiation light; a distribution unit distributing components corresponding to the first image of the irradiation light transmitted through the display unit to the first direction and distributing components corresponding to the second image of the irradiation light transmitted through the display unit to the second direction; and a cancellation unit cancelling luminance characteristics of the irradiation light distributed by the distribution unit.
1. A display apparatus allowing a first user positioned in a first direction to visually recognize a first image and allowing a second user positioned in a second direction different from the first direction to visually recognize a second image, comprising:
a display unit displaying a combined image formed by combining the first image with the second image;
an irradiation unit irradiating the display unit displaying the combined image with irradiation light;
a distribution unit distributing components corresponding to the first image of the irradiation light transmitted through the display unit to the first direction and distributing components corresponding to the second image of the irradiation light transmitted through the display unit to the second direction; and
a cancellation unit cancelling luminance characteristics of the irradiation light distributed by the distribution unit,
wherein the cancellation unit includes an open-area ratio correction unit including an optical filter including first and second open areas configured to transmit the irradiation light transmitted through the display unit,
wherein sizes of at least the first open areas are gradually reduced in a parallax direction.
2. The display apparatus according to claim 1 ,
wherein the optical filter is a color filter, and
the open-area ratio correction unit is a black matrix.
3. The display apparatus according to claim 2 ,
wherein the sizes of the first open areas of the black matrix are reduced in units of sub-pixels or in units of pixels of the color filter in accordance with coordinates in the parallax direction.
4. The display apparatus according to claim 1 ,
wherein the cancellation unit further includes
a luminance correction unit correcting image signals of the first and second images so that luminance of pixels for the first image at coordinates farther from the first user becomes higher and the luminance of pixels for the first image at coordinates closer to the first user becomes lower and so that luminance of pixels for the second image at coordinates farther from the second user becomes higher and the luminance of pixels for the second image at coordinates closer to the second user becomes lower.
5. The display apparatus according to claim 4 ,
wherein the cancellation unit further includes
a color filter transmitting the irradiation light transmitted through the display unit, in which at least one of a film thickness and density is adjusted in accordance with coordinates.
6. The display apparatus according to claim 1 ,
wherein the cancellation unit further includes
an irradiation control unit controlling the irradiation unit so as to cancel luminance characteristics of the irradiation light distributed by the distribution unit.
7. The display apparatus according to claim 1 ,
wherein sizes of the first open areas are gradually reduced in the parallax direction, and sizes of the second open areas are gradually increased in a direction that is opposite to the parallax direction.
8. An electronic apparatus allowing a first user positioned in a first direction to visually recognize a first image and allowing a second user positioned in a second direction different from the first direction to visually recognize a second image, comprising:
an image combining unit combining the first image with the second image to generate a combined image;
a display unit displaying the combined image;
an irradiation unit irradiating the display unit displaying the combined image with irradiation light;
a distribution unit distributing components corresponding to the first image of the irradiation light transmitted through the display unit to the first direction and distributing components corresponding to the second image of the irradiation light transmitted through the display unit to the second direction; and
a cancellation unit cancelling luminance characteristics of the irradiation light distributed by the distribution unit,
wherein the cancellation unit includes an open-area ratio correction unit including an optical filter including first and second open areas configured to transmit the irradiation light transmitted through the display unit,
wherein sizes of at least the first open areas are gradually reduced in a parallax direction.
9. The electronic apparatus according to claim 8 ,
wherein the cancellation unit further includes a luminance correction unit correcting image signals of the first and second images so that luminance of pixels for the first image at coordinates farther from the first user becomes higher and the luminance of pixels for the first image at coordinates closer to the first user becomes lower and so that luminance of pixels for the second image at coordinates farther from the second user becomes higher and the luminance of pixels for the second image at coordinates closer to the second user becomes lower.
10. The electronic apparatus according to claim 8 ,
wherein sizes of the first open areas are gradually reduced in the parallax direction, and sizes of the second open areas are gradually increased in a direction that is opposite to the parallax direction.
