3D video TVs are gaining popularity - even though they are expensive. Many buyers are willing to pay a hefty price for the opportunity to watch 3D movies from the comfort of their home. For such TVs, special glasses are needed - how to choose them correctly so as not to spoil the viewing experience?
Types of 3D glasses
To choose the right 3D glasses, you first need to find out the technology used by the TV - it can be active or passive. For active technology, you need to purchase shutter glasses, and for passive - polarizing glasses. The main difference between shutter glasses and polarizing glasses is the presence of a compartment for a tiny battery or a charging connector. In addition, the shutter glasses are equipped with a power-on and charge indicator.
You can see the technology in the instructions for the TV or on the manufacturer's official website.
Polarized, or passive, 3D glasses are similar to glasses used in movie theaters. They work without various indicators, batteries and batteries, and the three-dimensional image is split when passing through the polarizing coating of the glasses, as a result of which each eye sees the picture intended for it. To avoid common mistakes when choosing 3D glasses, you need to know their key characteristics and features.
Choosing 3D glasses
When choosing shutter glasses, it is advisable to purchase models with a rechargeable battery in order to avoid frequent battery replacement after watching 3D films. One battery charge lasts forty hours, and its charging time is two to three hours. Glasses with a charge level indicator will also be a bargain, which allows you to monitor battery power consumption and not leave glasses on. The maximum working condition of high-quality 3D glasses should be less than the distance from the TV screen to the viewer.
Modern models of 3D shutter glasses are equipped with mini USB and micro USB connectors, with which the device can be charged from a laptop or computer.
Choosing polarized glasses, you should give preference to a model with linear polarization, which does not limit the freedom of movement of the viewer's head. Also, for comfortable viewing of three-dimensional films, it is advisable to purchase 3D glasses with high transmittance - a parameter responsible for the transparency of the lenses of this device.
When choosing both shutter glasses and polarizing glasses, be sure to make sure that the model you choose is compatible with the 3D TV for which it is being purchased. In addition, it is important to check with the seller the warranty period and the package contents - when purchasing polarizing glasses, several pairs may be included in the kit.
