High resolution autosterioscopic display
First Claim
1. An autostereoscopic display comprising:
- a backlight unit;
a display panel which displays an odd numbered column field and an even numbered column field in a time sequential manner using light emitted from the backlight unit, wherein the odd numbered column field comprises odd numbered columns of a left eye image and odd numbered columns of a right eye image, and the even numbered columns field comprises even numbered columns of the left eye image and even numbered columns of the right eye image;
a viewing zone separating unit which separates viewing zones of a right eye image and a left eye image of the odd numbered column field and the even numbered column field;
a polarizer which polarizes the light output from the display panel to produce first polarized light;
a polarization switch which converts the first polarized light into second polarized light that is polarized in a different direction than the first polarized light, wherein the polarization switch is switched in synchronization with the displaying of the odd numbered column field and the even numbered column field by the display panel; and
a birefringent plate which has a refractive index that varies according to a polarization of incident light,wherein the first polarized light is formed with the odd numbered column field and the second polarized light is formed with the even numbered column field in a time sequential manner, and the second polarized light is shifted with respect to the first polarized light by the birefringent plate so that the odd numbered columns and the even numbered columns of the left eye image form a combined image for a left eye and the odd numbered columns and the even numbered columns of the right eye image form a combined image for a right eye to provide autostereoscopic display.

Abstract
A high resolution autostereoscopic display includes: a backlight; a display panel forming an image using the backlight light; a viewing zone separator separating viewing zones of right and left eye images of the display panel; a polarizer polarizing the light from the display panel into first polarized light; a polarization switch converting the first polarized light into second polarized light that is polarized in a different direction; and a birefringent plate including a refractive index that varies consistent with the polarization of incident light. Images corresponding to odd and even numbered column fields are formed with the first and second polarized light, time-sequentially. The birefringent plate shifts the second polarized light with respect to the first. A three-dimensional image with the full resolution of the display panel is formed by images corresponding to an odd-numbered and even-numbered column field with the first and shifted second polarized light, respectively.
