Three dimensional televisions and movies offer an incredible entertainment experience. They make movies come to life – characters enter the domain of your living room and it can feel like you are really inside the story. Over the years, 3D technology has drastically changed – the technology has become more advanced and it has made the act of watching a 3D movie a lot more enjoyable. When it comes to 3D televisions, you typically have two options: active and passive. There are a lot of technological differences between the two and understanding what these dissimilarities are is important when you are looking for a 3D television to buy. Here are some of the differences between active and passive 3D TVs.
First and foremost, it is important to understand the basic technological differences. When you go to a 3D movie, you aren’t really watching anything technologically spectacular – it is merely a high definition optical illusion. The film is created with two different image lines – the screen in the movie theater is coated to enhance those two different lines. You are then given special glasses, from a company like American Paper Optics, that merge those two lines. A passive 3D TV utilizes the same technology – the screen is specially made to work with a pair of glasses to make the image look three-dimensional.
When it comes to active 3D technology, you have a more complicated system at play. Active 3D technology utilizes the power of moving parts, shutters and unique filming techniques to make the image or movie come to life. Basically, the television shows two different images at different times – like a constantly blinking shutter. You then have a pair of glasses that have a unique shutter system that brings those blinking images together. The reason why it is called “active” 3D is because it is literally active – you need a source of power to turn on the glasses and the television is a lot more technologically advanced.
If you are wondering what is better, you have to basically explore both to find out what you prefer. When it comes down to it, many people prefer active 3D technology because it can be used on any flat screen television – you don’t need a pre-coated screen. And many people prefer passive technology because it is more affordable and the technology is rather simple, which means that you don’t need to wear heavy glasses that can sometimes get in the way of your movie watching experience.
In the end, both passive and active 3D televisions offer a number of their own unique advantages and disadvantages. But the one thing you need to understand is that passive 3D technology doesn’t require any moving parts or any alternate source of energy. Active 3D technology, on the other hand, requires moving parts, complex shutters and other computerized functions. In the end, the technology is rather new, so it is only a matter of time before we find out what the wider market preference is – in the meantime, though, it is up to the consumer to explore both.
