Parallax Barrier
A parallax barrier is a device placed in front of an image source, such as a liquid crystal display, to allow it to show a stereoscopic or multiscopic image without the need for the viewer to wear 3D glasses. Placed in front of the normal LCD, it consists of an opaque layer with a series of precisely spaced slits, allowing each eye to see a different set of pixels, so creating a sense of depth through parallax in an effect similar to what lenticular printing produces for printed products and lenticular lenses for other displays. A disadvantage of the method in its simplest form is that the viewer must be positioned in a well-defined spot to experience the 3D effect. However, recent versions of this technology have addressed this issue by using face-tracking to adjust the relative positions of the pixels and barrier slits according to the location of the user's eyes, allowing the user to experience the 3D from a wide range of positions. Another disadvantage is that the horizontal pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parallax Barrier Vs Lenticular Screen
Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight and is measured by the angle or semi-angle of inclination between those two lines. Due to foreshortening, nearby objects show a larger parallax than farther objects when observed from different positions, so parallax can be used to determine distances. To measure large distances, such as the distance of a planet or a star from Earth, astronomers use the principle of parallax. Here, the term ''parallax'' is the semi-angle of inclination between two sight-lines to the star, as observed when Earth is on opposite sides of the Sun in its orbit. These distances form the lowest rung of what is called "the cosmic distance ladder", the first in a succession of methods by which astronomers determine the distances to celestial objects, serving as a basis for other distance measurements in astronomy forming the higher rungs of the ladder. Parallax also affects optical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nintendo 3DS
The is a handheld game console produced by Nintendo. It was announced in March 2010 and unveiled at E3 2010 as the successor to the Nintendo DS. The system features backward compatibility with Nintendo DS video games. As an eighth-generation console, its primary competitor was Sony's PlayStation Vita. The handheld's most prominent feature is its ability to display stereoscopic 3D effects without the use of 3D glasses or additional accessories, and it offers new features such as the StreetPass and SpotPass tag modes, powered by Nintendo Network; augmented reality using its 3D cameras; and Virtual Console, which allows owners to download and play games originally released on older video game systems. The Nintendo 3DS was released in Japan on February 26, 2011, and worldwide beginning in March 2011. Less than six months later on July 28, 2011, Nintendo announced a significant price reduction from US$249 to US$169 amid disappointing launch sales. The company offered ten fr ...

Mass Production
Mass production, also known as flow production or continuous production, is the production of substantial amounts of standardized products in a constant flow, including and especially on assembly lines. Together with job production and batch production, it is one of the three main production methods. The term ''mass production'' was popularized by a 1926 article in the ''Encyclopædia Britannica'' supplement that was written based on correspondence with Ford Motor Company. ''The New York Times'' used the term in the title of an article that appeared before publication of the ''Britannica'' article. The concepts of mass production are applied to various kinds of products: from fluids and particulates handled in bulk (food, fuel, chemicals and mined minerals), to parts and assemblies of parts (household appliances and automobiles). Some mass production techniques, such as standardized sizes and production lines, predate the Industrial Revolution by many centuries; however, ...

Image
An image is a visual representation of something. It can be two-dimensional, three-dimensional, or somehow otherwise feed into the visual system to convey information. An image can be an artifact, such as a photograph or other two-dimensional picture, that resembles a subject. In the context of signal processing, an image is a distributed amplitude of color(s). In optics, the term “image” may refer specifically to a 2D image. An image does not have to use the entire visual system to be a visual representation. A popular example of this is of a greyscale image, which uses the visual system's sensitivity to brightness across all wavelengths, without taking into account different colors. A black and white visual representation of something is still an image, even though it does not make full use of the visual system's capabilities. Images are typically still, but in some cases can be moving or animated. Characteristics Images may be two or three-dimensional, such as a ph ...

Autostereoscopy
Autostereoscopy is any method of displaying stereoscopic images (adding binocular perception of 3D depth) without the use of special headgear, glasses, something that affects vision, or anything for eyes on the part of the viewer. Because headgear is not required, it is also called "glasses-free 3D" or "glassesless 3D". There are two broad approaches currently used to accommodate motion parallax and wider viewing angles: eye-tracking, and multiple views so that the display does not need to sense where the viewer's eyes are located. Examples of autostereoscopic displays technology include lenticular lens, parallax barrier, and may include Integral imaging, but notably do not include volumetric display or holographic displays. Technology Many organizations have developed autostereoscopic 3D displays, ranging from experimental displays in university departments to commercial products, and using a range of different technologies. The method of creating autostereoscopic flat panel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LG Corp
LG Corporation (or LG Group) (), formerly Lucky-Goldstar from 1983 to 1995 (Korean: ''Leokki Geumseong''; ), is a South Korean multinational conglomerate founded by Koo In-hwoi and managed by successive generations of his family. It is the fourth-largest chaebol in South Korea. Its headquarters are in the LG Twin Towers building in Yeouido-dong, Yeongdeungpo District, Seoul. LG makes electronics, chemicals, and telecommunications products and operates subsidiaries such as LG Electronics, Zenith, LG Display, LG Uplus, LG Innotek, LG Chem, and LG Energy Solution in over 80 countries. History LG Corporation was established as Lak Hui Chemical Industrial Corp. in 1947 by Koo In-hwoi. In 1952, Lak Hui (락희) (pronounced "Lucky"; now LG Chem) became the first South Korean company to enter the plastics industry. As the company expanded its plastics business, it established GoldStar Co. Ltd. (now LG Electronics Inc.) in 1958. Both companies Lucky and GoldStar merged to ...
