Facts About 3D Televisions

Home 3D televisions in several ways. They can use active shutter glasses along with a high refresh rate to generate an image in one eye at a time or can be used autosterescopic shows. They differ from the 3D animation we've seen in theaters that use of passive polarized 3D technology with naočale.Active Shutter glasses are not polarized and autosteroscopic displays do not require special glasses at all.

3-D movies playing in theaters using passive 3D technology. Two images are displayed simultaneously. Audiences wear polarized glasses that filter the image in the left and right eye in the form of a 3D effect.

Home 3D TV sets, such as images and delivered at a rate of 120 frames / second. Because images are displayed alternatively on the right and left eyes, each eye receives an effective 60 frames per sekundi.Active Shutter glasses are synchronized to the TV via Bluetooth, WiFi, or wireless frequencies. When the TV is showing images created for the left eye, right lens at the viewer an active shutter glasses turned opaque, which blocks the image from the viewer could see his right eye. Similarly, when the TV displays the image to the right eye, left the lens turns opaque.

Active Shutter Glasses and the batteries are quite expensive. They often cost $ 150 a couple. On the other hand, polarized glasses are the cost - usually around $ 1 or $ 2 It would be best if you can see 3D TV without naočala.Proizvođača who are developing autosterescopic displays use optical components such as lenses or parallax barrier lenses to create different images to each eye.

The disadvantage of this type of technology that are designed to create a good 3-D image only at a certain distance, and the narrow range of viewing angles. Lens system using lenses LG, for example, requires looking at the ideal distance of exactly 13 feet. Parallax barriers, such as those used by Sharp 3D televisions, liquid crystal can be formed by lenses or hard one.Tekućih crystal type has the advantage of having the ability to shut down to allow for conventional TV viewing on a single set.

In recent times we have seen an alternative to these screens appear, such as integral photography using a very fine paintings that are seen through a series of spherical convex lens in which the brain look like 3-D images. It is hard lens type parallax barrier. HoloVizio has developed a kind of parallax called "continuous motion", which uses "voxels." These are replacements for the number of pixels that project a beam of light in many directions at once.

If these types of 3D glasses without TVs gain popularity, people will be asked to design rooms that are long and narrow to be optimal for viewing by most people. In the meantime, active 3D technology continues to drop in price, allowing more and more people can afford those kinds of home units, working together with the 3-D Blu-ray DVD players and movies 3D online.
