LG Electronics is a South Korean multi-national electronics company headquartered in Yeouido-dong, Seoul, South Korea. LG Electronics is a part of LG Corporation, the fourth largest chaebol in South Korea, and often considered as the pinnacle of LG Corporation. LG Electronics is also the world's second largest television manufacturer behind Samsung Electronics.
As a means to educate consumers regarding the technologies associated with 3D television (3D TV), LG Electronics initially published a website in 2011, titled "3D Entertainment Now" (http://www.3dentertainmentnow.com). Shefik developed this website as a UI Developer at Publicis Modem, where he incorporated technologies such as PHP and WordPress.
3D TV is television that conveys depth perception to the viewer by employing techniques such as stereoscopic display, multi-view display, 2D-plus-depth, or any other form of 3D display. Most modern 3D television sets use an active shutter 3D system or a polarized 3D system, and some are autostereoscopic without the need of glasses. As of 2017, most 3D television sets and services are no longer available from manufacturers.
According the website information published in 2011, not all 3D TV images are created equal. Before you buy a 3D TV, be sure you understand the differences between the two types of technologies and what they mean for your viewing experience (Active TV vs. Passive TV).
There are two competing technologies that create 3D effects: passive and active. Active has been the most widely used 3D TV technology. However, new passive technology is rapidly gaining in popularity due to its lightweight and inexpensive glasses, allowing for more people to enjoy 3D TV together. In addition to how active 3D and passive 3D technologies actually work, the main difference is the 3D glasses that are used with them.
Active 3D works this way: An electronic signal is paired to active shutter 3D glasses from the television, and it opens and closes (or "shutters") the left and right lenses of the glasses rapidly to match the images on the screen. In other words, they dim the left lens and then the right lens in quick succession. The brain sees the fast-moving alternating frames as 3D. The complicated technology can make the active eyeglasses expensive and heavy.
Passive 3D operates by separating images for each eye and then converging them to deliver the 3D images. Different kinds of light are blocked in each eye and this creates the illusion of depth. This allows the 3D passive glasses to be significantly more affordable and lighter than active glasses. Some say the passive 3D TV picture resolution quality is not as good as an active 3D TV, although recent 3D TV tests have shown consumer preferences for the passive 3D TV picture image.
