As far as HDTV is concerned, at present, it is holding the top position in the market with all the latest technology and perfection-personified clarity of picture and images, whereas , 3D TV sets, which is a combination of advanced technology and old-fashioned brain trickery, will surely pop your eyes with its special effect that make you feel things floating out of your sets.
Electronic giant Philips’s WoWvx displays works on multiview lenticular lens technology. In the 2D-plus-depth format, pixels are bundled with information that indicates their depth, using 256 grayscale shades. A microlens in front of the LCD panel then uses that information to provide nine different views for each pixel, projected to various viewing angles.
This set-up ensures that each eye receives a slightly different picture, which is interpreted by the brain as a depth cue. The different views for each pixel also ensure that viewers are relatively free to move, reducing the “sweet spot” phenomenon that plagues less sophisticated systems. The 2D-plus-depth format only increases the bandwidth of the signal by 5-20%, which is unlikely to be seen as much of a hurdle for the industry.
Philips has been demonstrating the WoWvx systems at expos for a few years now, showing off the dynamic color and large screen sizes. The last one was 52 inches, with full HD 1920×1080 resolution (although the linear resolution takes a hit when presenting multiple views). Forty-two-inch 3D displays are already on the market.
The shape of the future
Most other companies interested in 3D TV, such as Samsung and Holografika, are working on models similar to Philips, and ignoring laser-recorded holographs as a display medium. This means if 3D TV launches onto the consumer market before 2020, it’s likely to be based on multi-angle pixel projection. The more experimental 3D technologies, such as Dr Peyghambarian’s and the projector-based Cheoptics360 system are most likely to find selective applications in medicine, the military, and engineering.
