Abstract
A stereoscopic image display device including a display panel including a plurality of sub-pixels arranged in a matrix defined by a horizontal direction and a vertical direction, the display panel having a changeable display direction; and a parallax unit on the display panel and including a plurality of optical elements having a tilt angle of 30° to 60° relative to the vertical direction and a pitch corresponding to a multiple of a pitch of the sub-pixels. Among the sub-pixels located to correspond to each of the optical elements, at least two sub-pixels, adjacently arranged, display the same view image.
Claims12
A stereoscopic image display device, comprising:
- a display panel including a plurality of sub-pixels arranged in a matrix defined by a horizontal direction and a vertical direction, the display panel having a changeable display direction;
- and
- a parallax unit on the display panel and including a plurality of optical elements having a tilt angle of 30° to 60° relative to the vertical direction and a pitch corresponding to a multiple of a pitch of the sub-pixels,
- wherein, among the sub-pixels located to correspond to each of the optical elements, at least two sub-pixels, adjacently arranged, display the same view image,
- wherein the display panel displays an image in one of a horizontal viewing mode, a vertical viewing mode, and a diagonal viewing mode, and
- wherein, in one of the horizontal viewing mode, the vertical viewing mode, and the diagonal viewing mode, an initial view map constructed to cause the sub-pixels of the display panel to separate an input image into r view images (r being a natural number of 3 or more) is amended, and the image is displayed using the amended view map to display k view images (k being a natural number of 2 or more, being less than r) so that the at least two sub-pixels, adjacently arranged, display the same view image.
A driving method of a stereoscopic image display device, having
- a display panel including a plurality of sub-pixels arranged in a matrix defined by a horizontal direction and a vertical direction to display images with the display panel having a changeable display direction, and a parallax unit on the display panel and including a plurality of optical elements having a tilt angle of 30° to 60° relative to the vertical direction and a pitch corresponding to a multiple of the pitch of the sub-pixels, the driving method comprising:
- constructing an initial view map to cause the display panel to display r view images (r being a natural number of 3 or more);
- amending the initial view map to cause sub-pixels displaying the r view images to display k view images (k being a natural number of 2 or more, being less than r) by defining k regions formed by dividing the pitch of each optical element into k equal parts, causing sub-pixels corresponding to an lth region of the k regions (with ‘l’ being a natural number of ‘k’ or less) to display the same view image and causing sub-pixels corresponding to the different regions to display different view images;
- and
- displaying a plurality of views separated from the display image.
