Abstract
An autostereoscopic display comprises an array of display pixels arranged in rows and columns, and a liquid crystal lens structure disposed over the display pixel array. The liquid crystal lens structure includes an array of elongated lens units, each having a lens direction extending across a column direction of the display pixel array. An alignment layer has a rubbing direction oriented substantially perpendicular to the lens direction. A half-wave plate is disposed between the display pixel array and the liquid crystal lens structure and is configured to rotate a polarization direction of transmitted light such that the polarization direction is substantially parallel to the rubbing direction.
Claims5
An autostereoscopic display device, comprising:
- a liquid-crystal panel, the liquid-crystal panel comprising:
- a plurality of display pixels configured to generate images, the display pixels being arranged in rows and columns to form a display pixel array and to define a row direction and a column direction;
- a first alignment layer;
- a second alignment layer;
- and a first liquid-crystal layer disposed between the first alignment layer and the second alignment layer, wherein an alignment direction of the first alignment layer is substantially orthogonal to an alignment direction of the second alignment layer;
- a backlight module;
- a first polarizer disposed above the backlight module;
- a second polarizer disposed above the second alignment layer;
- a half-wave plate disposed above the second polarizer;
- and
- a liquid-crystal lens array disposed above the half-wave plate,
- wherein the liquid-crystal lens array comprises a plurality of lens units extending parallel to one another, the lens units being configured to form a plurality of pixel groups on the display pixel array, and to define boundaries between adjacent pixel groups so as to produce a multi-view separation effect required for stereoscopic image display.
A display device, comprising:
- a liquid-crystal panel configured to display images, the liquid-crystal panel comprising:
- a first alignment layer;
- a second alignment layer disposed above the first alignment layer;
- and a liquid-crystal layer disposed between the first alignment layer and the second alignment layer, wherein an alignment direction of the first alignment layer is substantially orthogonal to an alignment direction of the second alignment layer;
- a backlight module;
- a first polarizer disposed between the backlight module and the first alignment layer, the first polarizer having a transmission axis substantially parallel to the alignment direction of the first alignment layer;
- a second polarizer disposed above the second alignment layer, the second polarizer having a transmission axis substantially parallel to the alignment direction of the second alignment layer;
- a liquid-crystal lens disposed above the second polarizer;
- and
- a half-wave plate disposed between the second polarizer and the liquid-crystal lens, the half-wave plate being configured to rotate a polarization direction of light incident on the liquid-crystal lens.
