How 3D Monitors Work

There is a new breed of LCD available that can turn your computer into games 3d virtual reality type experience. These monitors work with polarized glasses and allow to take 3D images of the depth or even appear off the screen. They create depth in images by simulating the way your brain perceives depth by showing different images for each eye.

When a person looks at an object in 3 dimensions, he sees the object from different angles. Although the eyes are close enough, if you close one eye then the other, you will see two slightly different images. The brain instantly analyzes the differences between the two images and is able to detect the distance of each object is the viewer, creating our perception of depth. So the key is 3D monitors to display separate images for each eye, simultaneously from cameras installed within inches of each other.

Create images to be displayed to each eye is the simplest part. 3D display drivers can quickly create an image from two different angles in a game. The difficult part is to display the correct image to each eye. The newest breed of monitors games 3d does this polarization of light using.


The polarization has to do with the direction of light waves at an angle. Light travels in waves, and when the waves of light emission from a monitor are rolling in a sense, they are polarized. Polarized lenses have filters that can allow or block light waves depending on their orientation.

For 3D displays, the light of the image he must be displayed in the left eye is polarized at an angle of 135 degrees. The light for the right eye is polarized at an angle of 45 degrees. The lenses are configured to allow light from the correct angle and completely block the light arrives at an angle of 90 degrees. Using this method the 3D monitor can display an image that looks like gray to the naked eye, but seen through polarized lenses would be quite dark in the left eye, and completely white on the right.

Although the end result is that the monitor shows flat just separate images to each eye, the effect can be surprising. Depending on the options you choose, the game will either seem to be popping out of the screen to you or behind your monitor. This second option is much more popular, and the many games, it looks as if you are looking through a window to another world.

This new type of 3D computer screen is now available from several manufacturers. As other manufacturers enter the game arena and developers are beginning to change their games for 3D monitors, this technology could become the standard in electronic games.
