3D technology has been around for decades now. Before, it was limited to the big screen. Today, however, you can enjoy the 3D experience right from your couch. If you are like me, you want to lose yourself in your entertainment. When it comes to 3D technology, though, I initially struggled to understand exactly what I was looking for. I discuss the benefits of adding a projector to your home theater set up in many different articles. Today I want to focus on the 3D projector and what this technology means for you.
So what is a 3D projector?
A 3D projector uses specialized technology that allows it to produce a three-dimensional image on a two-dimensional surface. The viewer is able to see depth from a 3D projector, unlike a traditional projector.
Ready to learn more about 3D projectors? Below I outline how these projectors work, the pros and cons of investing in such technology and the types of glasses you can use to best view 3D images.
3D projectors are similar to 2D projectors in many ways. They typically contain the same hardware options, such as DLP
The type of data transmittal affects which kind of 3D projector you need. 3D images are transmitted through the use of one of four format techniques. These include frame sequential, frame packing, side-by-side, and checkerboard.
3D-ready projectors can lead to disappointment for some buyers. This is because they are designed only to handle frame sequential data transmissions. Frame sequential data transmissions are often the least expensive 3D formats, which makes these types of projectors the cheapest of the 3D family.
Frame sequential signals can be limited; they send a full resolution image at 120 frames per second, which may be considered slightly excessive when considering the bandwidth required to do so.
3D-ready projectors require very specific data sources, such as computers equipped with NVIDIA’s 3D Vision capabilities. This means that not all Blu-ray players will be capable of providing the correct data signals for these projectors to render 3D images.
Full 3D projectors, however, are able to handle any of the four major data formats. Although every projector has its own specifications, most full 3D projectors offer 1080p images. They are also typically capable of handling source media from HDMI or Blu-ray players, making them a universal 3D projector.
Many of the pros and cons associated with 3D projectors mirror those of their 2D brethren. However, some are 3D-specific in nature. Below are the top pros and cons regarding your investment in a 3D projector.
Yes, all 3D images require the use of special glasses. However, gone are the days of having to wear goofy 3D glasses with one red lens and one blue lens. Today’s 3D glasses are sleeker and modernized.
There are two main types of 3D glasses on the market today: polarized passive and active shutter. Let’s take a look at the major differences between the two.
Passive polarized glasses look more like sunglasses today. They are simply, yet sleek. Requiring no additional pieces, they consist of a lightweight frame and lenses. If you wear regular glasses, these 3D versions typically fit over your every-day ones.
Passive polarized glasses are often the least expensive option when it comes to 3D viewing. They are made of one piece, which allows the eyes to consistently view the same quality image without flickering. However, they dilute the resolution of the image by up to half. They are also known for making text and straight-lined geometric shapes more pronounced and noticeable, which may be a problem for some viewers.
Active shutter glasses are powered models designed to sync with the rapidly changing images on your screen. They are bulkier than the passive models due to the included battery that powers them. (This is often in the form of a watch battery or some other rechargeable power source.) They also include an on/off button and a transmitter that receives and translates the data signals for you.
Active shutter glasses, because they sync with your source, provide viewers with the same resolution as the image. However, they may subject the eye to flickering, due to the rapid shutter speeds. This may cause some viewers discomfort. They can also be expensive, often up to three times the cost of a passive polarized model.
