High-resolution multi-view 2D/3D display with HxDP Technology for enhanced stereoscopic viewing
The low-temperature polysilicon thin-film-transistor (TFT) color liquid crystal display (LCD) 2D/3D module prototype features a wide quarter video graphics array (WQVGA) resolution that enables autostereoscopic images. Incorporating NLT’s proprietary HxDP pixel array, the 3.1-inch (79 millimeters diagonal), six-view display prototype enables users to view high-density stereoscopic images without special 3-dimensional (3D) glasses. The prototype also features a wide stereoscopic viewing angle and NLT’s multi-view technology with multi-camera data, which allows users to see multi-angle images with smooth motion parallax, providing a more realistic 3D viewing experience.
Conventional LCDs are based on square pixel arrangements, with RGB sub-pixels distributed in vertical stripes with two pixels required to display a 3D image, cutting the display’s horizontal resolution in half. With NLT’s HxDP technology, the six-view, 2D/3D 3.1-inch display prototype module is composed of horizontally striped RGB color pixels, each consisting of three sub-pixels that are striped horizontally and split in 1/6 lengthwise, resulting in a resolution six times that of 3D LCD modules constructed with vertically striped pixels. Alternating displays of the horizontal pixels for each eye produces the desired 3D images. The HxDP technology also makes it possible for 2D and 3D images to be displayed simultaneously in the same resolution on the same screen without the need for 3D glasses.
One common issue with 3D displays is 3D cross talk, which occurs when the human visual system mixes left-eye and right-eye information, causing the 3D effects to be limited or decreased. NLT’s new HxDP 3D technology results in displays with reduced levels of overall 3D cross talk and a wide 3D viewing area, allowing easy viewing of the images.
