Abstract
An autostereoscopic image output device includes an image panel having an array of image pixels defining an image, the image pixels being arranged in rows and columns. An array of parallel lenticular elements is positioned over the image panel, the lenticular elements having optical focal axes that are slanted at an angle (φ) to the image pixel columns. The image output device is operable in first and second modes, with the image panel and lenticular element array rotated by 90 degrees between the modes, thereby providing a landscape mode of operation and a portrait mode of operation, the slant angle φ in the landscape mode satisfies 1≧φ≧½.
Claims18
An autostereoscopic image output device comprising:
- a panel of pixels having a rectangular shape and display areas and arranged in an image defining array of rows and columns, the rows including more pixels than the columns;
- and
- an array of lenticular elements positioned parallel to one another over the panel of pixels and having optical focal axes slanted at an angle to the columns,
- wherein the panel and the array of lenticular elements together are rotatable by 90 degrees to provide autostereoscopic effects in landscape and portrait modes of operation,
- wherein a slant of the angle in the landscape mode satisfies:
- 1≧tangent of the angle≧½,
- wherein the array of lenticular elements is configured to provide nine views at nine different horizontal distances between a center of a pixel of the panel of pixels and a lens axis of a lenticular element of the array of lenticular elements, and
- wherein the nine different horizontal distances are −4, −3, −2, −1, 0, 1, 2, 3, 4 times a column pitch, and correspond to the nine views.

An autostereoscopic device comprising:
- a panel rotatable by 90 degrees to provide autostereoscopic effects in landscape and portrait modes of operation, the panel including:
- an orthogonal array of pixels arranged in rows and columns, each pixel having a pixel display area including a width in a direction of the rows longer than a height in a direction of the columns;
- and
- an array of lenticular elements arranged parallel to one another over the array of pixels, wherein each lenticular element has an optical focal axis slanted at an angle to the columns, and wherein in the landscape mode the slant of the angle satisfies:
- tangent of the angle≈twice a ratio of the width to the height,
- wherein the array of lenticular elements is configured to provide nine views at nine different horizontal distances between a center of a pixel of the orthogonal array of pixels and a lens axis of a lenticular element of the array of lenticular elements, and
- wherein the nine different horizontal distances are −4, −3, −2, −1, 0, 1, 2, 3, 4 times a column pitch, and correspond to the nine views.
