Abstract
A display apparatus for displaying a three-dimensional image using a parallax barrier scheme includes a display module having a display region in which a plurality of pixels are arranged, and a parallax barrier facing the display region. In the parallax barrier, a plurality of aperture regions are formed as light-transmissive regions so that each one of the aperture regions corresponds to a predetermined number of the pixels. In one embodiment, each of the aperture regions is in a shape that exhibits an identical shape when rotated by 90 degrees.
Claims25
A display apparatus for displaying a three-dimensional image using a parallax barrier scheme, comprising:
- a display module having a display region having a plurality of pixels;
- and
- a parallax barrier unit facing the display region, the parallax barrier unit being configured to display a parallax barrier having a plurality of aperture regions for at least a portion of the display region, each of the aperture regions corresponds to a predetermined number of pixels, each of the aperture regions being in a shape that exhibits an identical shape when rotated 90 degrees.
A display apparatus for displaying a three-dimensional image using a parallax barrier scheme, comprising:
- a display module having a display region in which a first pixel, a second pixel adjacent to the first pixel in a first direction, a third pixel adjacent to the first pixel in a second direction perpendicular to the first direction, and a forth pixel adjacent to the third pixel in the first direction are formed;
- a parallax barrier unit facing the display region, the parallax barrier unit being configured to display a parallax barrier;
- a control unit allocating pixel data to the pixels;
- and
- a judgment unit judging a rotational condition of the display module,
- wherein the control unit allocates a same pixel data as a right eye image to the first pixel and the second pixel and also allocates a same pixel data as a left eye image to the third pixel and the forth pixel when the judgment unit judges the rotational condition of the display module to be in a first rotational condition, and
- wherein the control unit allocates a same pixel data as a right eye image to the second pixel and the forth pixel and also allocates a same pixel data as a left eye image to the first pixel and the third pixel when the judgment unit judges the rotational condition of the display module to be in a second rotational condition that is rotated clockwise by 90 degrees from the first rotational condition.
An image control method for displaying a three-dimensional image using a parallax barrier scheme, comprising:
- allocating a same pixel data as a right eye image to a first pixel and to a second pixel that is adjacent to the first pixel in a first direction and allocating a same pixel data as a left eye image to a third pixel that is adjacent to the first pixel in a second direction perpendicular to the first direction and to a forth pixel that is adjacent to the third pixel in the first direction, when a display module is in a first rotational condition;
- and
- allocating a same pixel data as a right eye image to the second pixel and to the forth pixel and allocating a same pixel data as a left eye image to the first pixel and to the third pixel, when the display module is in a second rotational condition that is rotated clockwise by 90 degrees from the first rotational condition.
A display apparatus for displaying a three-dimensional image using a parallax barrier scheme, comprising:
- a display module having a display region in which a plurality of pixels are arranged;
- and
- a parallax barrier unit facing the display region, the parallax barrier unit being configured to display a parallax barrier having a plurality of aperture regions for at least a portion of the display region such that each of the aperture regions corresponds to a predetermined group of pixels, each of the aperture regions being arranged and having a shape such that a left eye and a right eye of a viewer respectively receive light from mutually exclusive subgroups of pixels among said group of pixels when the display module is oriented horizontally with respect to the eyes of the viewer and such that the left eye and the right eye of the viewer respectively receive light from mutually exclusive different subgroups of pixels among said group of pixels when the display module is oriented vertically with respect to the eyes of the viewer.
