As technology continues to advance, almost everything has been taken a notch higher. Display of images seems to be one of the biggest beneficiaries of advanced technology in the recent past. There are many types of image displays that have been devised but the most popular ones are active and passive 3D. While the concept is the same, the active and the passive 3D differ in a number of ways. They however have some features in common.
Active 3D is typically faster than passive 3D. This is because it alternates rapidly between the left and right eye, within the same space. This motion is really fast and requires that you wear special glasses to be able to properly view images that are under its influence. The lens of these special glasses are designed to turn from opaque, to translucent, to transparent. This continuous change occurs in sync with image transformation. What this means is that the image on the left side will only be displayed when the left lens is transparent and the right lens is opaque, and vice versa.
In order to ensure that the special glasses are effective, you need to ensure that your hardware is proper so that it can be recognized by the special glasses to facilitate proper transformation of images. Using infrared emitters will ensure compatibility between your hardware and the special glasses.
Passive 3D ensures that the image is simultaneously projected, on the left and the right eye, simultaneously. Special glasses are used to make sure that the images that are intended for either eye are viewed by that particular eye. These special glasses also block out images that not intended for viewing.
Active 3D appears to be a favorite of a lot of TV manufacturers. There are currently some plasma and LCD TVs that are 3D viewable. Active 3D is considered to be the mainstream of 3D TV according to a lot of TV manufacturers.
When it comes to image viewing, you will find that shutter glasses that are used in active 3D are not very comfortable and you will find some people complaining of headaches after using them for long periods. They are also more costly to buy than the glasses used in passive 3D. The advantage they have however is that they are well compatible with existing hardware sets and this therefore means that you do not have to incur an extra cost buying others.
Polarizing glasses are used with passive 3D technology. The disadvantage of these glasses is that they reduce the amount of light, so only half of the light that is emitted from the screen actually reaches the eye. This, in turn, dulls the image. But, there are advantages associated with these glasses. One advantage is that they are less costly when compared to glasses that are used for active 3D viewing. Wow, 3D technology is certainly taking the market by storm!
3D is only increasing in popularity and the speed at which the technology is advancing is unbelievable. Best 3D TV keeps you up to date with all these advances so you can make the most informed buying choices.
