Finding a TV with Passive 3D Technology
Watching a movie or a video, or TV with 3D content, on a 3D TV quite literally adds a whole other dimension to your viewing pleasure. You get a completely different experience than you do with the standard screens because of the extra depth projected.
What Is the Difference Between Active and Passive 3D?
The difference between passive 3D and active 3D TVs is in how the 3D glasses work in combination with the screen function to give you the three-dimensional effect.
- Passive: Passive 3D TVs and glasses use polarized glasses to filter even and odd horizontal lines on the TV to your eyes and create the 3D effect. Similar to what you may wear at the movies to watch something in 3D.
- Active: Active 3D TVs and glasses use battery operated crystal lenses to alternate your vision between your left and right eyes in rapid succession. These are also sometimes known as active shutter glasses.
Active glasses cannot work with a passive TV, and vice versa.
What Are Key Tech Specs of 3D TV?
Sony has manufactured both passive and active 3D TVs with a range of sizes and specifications.
- Smart TVs: Their 3D TVs released have been smart TVs with Bravia and Android operating systems to enjoy using the web and television on one device.
- Screens: Screen types may be high definition LCD or OLED.
- Accessories: You will need a 3D Blue-ray disc player to watch 3D movies on your TV or a 3D compatible satellite or cable box to watch 3D TV or streamed content.
- Glasses: This brand's passive 3D Glasses are lightweight and can go over other types of glasses.
What Else Should I Consider When Choosing a 3D TV?
There are a few things to consider when you are selecting a 3D TV for your home.
- Placement: Make sure your room is big enough to give you adequate distance for watching your TV for 2D and 3D content. You don't want to be too far away, but you don't want to be too close either. Check you have a TV stand or entertainment unit that will fit the TV and give enough surrounding ventilation.
- Size: Generally speaking, the bigger the better in terms of the viewing size and resolution so you get the most of the three-dimensional experience coming at you in your living room. 3D TV tends to work well on 4K TVs with HD screens (3840 by 2160 pixels).
- Connectivity: If you plan on streaming 3D content, the faster your internet connection the better. 3D images can take time to buffer on slower connections.
- Popularity: In very recent years the major TV manufacturers have stopped manufacturing new 3D TVs. However, fans of the technology predict just like 3D moves, the popularity will come back.
