Introduction to DLP Link 3D Technology
DLP Link 3D technology is a method of displaying 3D content using a DLP projector and a pair of specialized glasses. The technology uses a technique called “stereo imaging” to create the illusion of depth. This is achieved by displaying two separate images, one for the left eye and one for the right eye, which are then combined by the brain to create a single 3D image. The DLP Link 3D glasses play a crucial role in this process, as they are responsible for directing the correct image to each eye.
How DLP Link 3D Glasses Work
The DLP Link 3D glasses work by using a technology called “active shuttering.” This involves the use of liquid crystal on silicon (LCoS) or liquid crystal display (LCD) shutters that are embedded in the lenses of the glasses. These shutters are synchronized with the DLP projector to open and close in alternation, allowing each eye to see only the image intended for it. The shutters are controlled by an infrared signal that is emitted by the projector, which ensures that the glasses are perfectly synchronized with the image being displayed.
The Role of the Infrared Signal
The infrared signal emitted by the projector is a critical component of the DLP Link 3D technology. This signal is used to control the shutters in the glasses, ensuring that they open and close in perfect synchrony with the image being displayed. The signal is transmitted at a frequency of 60 Hz, which is the same frequency as the projector’s refresh rate. This ensures that the glasses are able to keep up with the rapid changes in the image, providing a smooth and seamless viewing experience.
