3D Glasses prices online in the Philippines December 2018

Nowadays, 3D TVs and also Video Projectors work by accepting an incoming 3D signal that is encoded by the content provider, which can be sent in several different ways. The TV has an internal decoder that can translate the type of 3D encoding used and displays the left and right eye information on the TV in such a way that it would appear and look like two overlapping pictures or images that are slightly out of focus. One image can be seen only by the left eye, while the other image is intended to only be seen by the right eye. To view this image properly, the user or viewer must wear glasses that are specially designed to receive the two separate images and pass them properly to the left and right eye. The 3D glasses work by giving a separate image to each of the user's eyes. The brain will then combine the two of the images that are overlapping in just one single image, then this will appear to be in 3D.

Which Is Better To Use

Passive Polarized Glasses look and wear much like sunglasses and require no additional power to work. It has enough front space to place over existing eyeglasses for those that need to. These are inexpensive which still depends on the type of frame style like the rigid vs flexible, plastic vs metal.

Active Shutter Glasses are slightly bulkier than passive glasses since they have batteries. Some use watch batteries and others provide rechargeable batteries. It has an on/off button and a transmitter that syncs the rapidly moving shutters for each eye with the onscreen display rate. These types of glasses are expensive than passive polarized glasses.

It also depends on the brand or model TV/video projector you purchase will determine which type of 3D glasses are required. When 3D TV was introduced, Mitsubishi, Panasonic, Samsung, and Sharp took the Active Shutter glasses route for LCD, Plasma, and DLP televisions although both Plasma and DLP TVs have been discontinued. Only LG and Vizio promoted Passive Glasses for 3D LCD TVs, and Toshiba, and Vizio although mostly using passive glasses, some of their LCD TVs did use Active Shutter Glasses. Sony used mostly the Active system but offered some TVs that use Passive which is quite confusing.

Through the new technology used to display images on Plasma TVs, only Active Shutter glasses can be used. The Active Shutter and Passive Glasses can both be used with LCD and OLED TVs - the choice was up to the manufacturer. Most consumer-based 3D-enabled video projectors require the use of Active Shutter 3D glasses, which allows the projector to be used with any type of screen or flat white wall. The manufacturers will provide 3D glasses with the set or projector. It will offer it as an accessory that had to be purchased separately. The production of 3D TVs has ended but 3D glasses are still available, but prices will vary.

As mentioned previously, active shutter glasses will be more expensive than passive polarized glasses. Also, another factor to take into consideration is that glasses that are branded for one brand of a TV or video projector, it may not work on the other's 3D-TV or video projector. So, if you wanted to use 3D glasses you should be using the same brand on it. If you have a Samsung 3D-TV, your Samsung 3D glasses will not work with Panasonic's 3D-TVs and vice versa. So, you can't share or borrow each other's 3D glasses.
