Introduction:
It is a technique of displaying stereoscopic image. The active shutter glasses are often criticised for being heavy, bulky and very expensive. Because they are technologically advanced they are more expensive than other 3D technology glasses. These are a bit heavy because of the fact of in-built battery power. These glasses require 3D television sets to perform. They cannot be used in cinemas or on any other television except the sets having 3D technology platform. It also works over the content coming from external Blu-ray’s players (Playstations) and 3D games with benefit. It can be used to present 3D images on CRT, Plasma, LCD and other types of video displays.
Advantage:-
⇒You can get a very good 3D effect when using active shutter 3D glasses. The liquid crystal shutter glasses are colour neutral, enabling 3D viewing in full colour spectrum. This system retains full resolution by combining the images over time.
Ways of Communication:
Infrared Emitter: – These glasses can perform over 3D platform only. This way of communicating is very easy and connects to a 3D television having 3D technology. These glasses are battery powered and have rechargeable in-built battery packed with the supplied USB cable for charging.
Radio Frequency Emitter: – The liquid crystal shutter glasses with Bluetooth technology for 3D TV/4D TV/PC are also battery powered and unlike the infrared instead of chargeable these have replaceable battery.
How it works?
These glasses are commonly used with 3D televisions, 3D projectors and some cinemas. Each lens contains transparent liquid crystal which turns black when the voltage is applied blocking one of the eyesight at a time. The glasses get instruction from the emitter or screen to darken each lens at a right time while the screen presents a different movie image to the unblocked eye for the completion of the illusion. For example, when the left lens turn black only the right eye see’s the image that the screen is intense for and vice versa. The timing synchronization equipped may be achieved via a wired signal, or wirelessly by either infrared, radio frequency (Bluetooth) or optical transmitter.
