Abstract
A stereoscopic display for displaying 3D images in the form of a stereo image pair. The stereoscopic display may include, but is not limited to, a display panel, a polarization layer, and an electro-optical panel. The display panel may include at least a first pixel and a second pixel. The polarization layer may include a first portion associated with the first pixel and a second portion associated with the second pixel.
Claims12
A stereoscopic display system comprising:
- a stereoscopic image processor;
- a display panel comprising:
- a plurality of first pixels and a plurality of second pixels, wherein the plurality of first pixels includes at least a first row of pixels, wherein the plurality of second pixels includes at least a second row of pixels, wherein the at least the first row of pixels and the at least the second row of pixels are interlaced,
- wherein the display panel receives image data associated with a first channel of a stereoscopic image pair and the at least one first row of pixels and image data associated with a second channel of a stereoscopic image pair and the at least one second row of pixels;
- a polarization rotation layer comprising:
- a plurality of first portions, each first portion being associated with a particular first row of the at least the first row, wherein each first portion of the polarization rotation layer is configured to impart a first polarization to the particular first row of the at least the first row, wherein each first portion is configured to impart a first polarization to light received from the particular first row during a first sub-frame of each stereoscopic image frame of a plurality of image frames;
- and
- a plurality of second portions, each second portion being associated with a particular second row of the at least the second row, wherein each second portion of the polarization rotation layer is configured to impart a second polarization to the particular second row of the at least the second row, wherein each second portion is configured to impart a second polarization to light received from the particular second row during the first sub-frame of each stereoscopic image frame of the plurality of image frames;
- and
- an electro-optical panel configured to:
- receive light from each first portion of the polarization rotation layer and each second portion of the polarization rotation layer during each sub-frame of each stereoscopic image frame;
- alter polarizations associated with each of the at least the first row and the at least the second row by imparting a first phase shift during each first sub-frame;
- alter polarizations associated with each of the at least the first row and the at least the second row by imparting a second phase shift during each second sub-frame;
- and
- receive control signals from the stereoscopic image processor to coordinate the first phase shift and the second phase shift with transitions between each first sub-frame and each second sub-frame and with transitions between each second sub-frame and each first sub-frame,
- wherein the stereoscopic display system is configured for full 3D (three-dimensional) resolution with respect to a total number of pixel rows.
