There is no doubt that you have probably become aware of the latest craze in modern electronics: 3D television. From the moment the public encountered 3D movies in the theaters, people have become interested in watching 3D movies in the comfort of their own homes. 3D technology is growing at a rapid pace. There are a variety of technologies used to enhance television and allow the viewed to watch in 3D. Some of these technologies are more costly than others, while others are easier to build. Before a manufacturer presents 3D television to the public, the company will have to consider these the pros and cons of each particular technology.
There are three primary ways of creating 3D televisions:
Lenticular viewing: This technology has been created by the well known company Philips. This form of technology gives people the opportunity to watch 3D without needing to wear 3D glasses. This may appeal to viewers who may not like the glasses and think they look silly. The lens in televisions that use lenticular viewing send a different image to each eye. The left eye will get an image that is different that the image that goes to the viewer’s right eye. A disadvantage to this form of 3D imaging is that these television sets have a limited viewing angle. Therefore, it is difficult for multiple viewers sitting in different spots to be able to see the movie in 3D.
Passive glass systems. Hyundai is currently devising a flat screen television that viewers can watch either 2D or 3D movies on. In order to watch the 3D images, it is necessary to wear the 3D glasses for this form of technology. In passive glass systems, the television screen displays two images which overlap. Due to the 3D glasses, each eye only views one image. The 3D effect developed using this method is great quality. lg smart tv 43 inch 4k These types of televisions are readily available for sale, even up to 40 inches.
Active glass systems. This form of technology works similarly to the way passive glass systems function. Rather than the 3D effect coming from the television, the effect mostly comes from the glasses. It’s necessary for the 3D glasses to be synchronized with the proper refresh rate on the television. Following this, the television alternates displays for the right and left eye. A specially devised shutter system in these glasses will ensure that only the right eye can see the images displayed for the right eye. Likewise, the same holds true for the left eye. As such, the refresh rate of the television is cut in half. Therefore, a minimum of 120Hz refresh rate is recommended in conjunction with active shutter glasses.
