Based on its FPR (Film Patterned Retarder) technology, LG's latest suite of Cinema 3D televisions involve a special circular polarizing film applied unto the panel, designed to transmit simultaneous left and right eye images to the viewer. Unveiled this year, LG's passive Cinema 3D series is undoubtedly the biggest competitor to the active 3D TV troops since its inception. Possible replacement for active shutter glasses? Are you game enough to try these? Enjoy! The Passive 3D Camp ![]() Sony, Samsung and Panasonic are some of the main players in this group. ![]() Each lens shutters on and off at about 50 or 60 times a second, which also explains why an active 3D TV needs to have a minimum of 120Hz (2 x 60Hz) refresh rate. These glasses also contain a receiver, which works in tandem with the TV's emitter to coordinate the shuttering lenses with the alternating frames. For instance, the left lens is darkened when the right picture frame reaches the right eye, and vice versa for the left eye. These lenses are filled with liquid crystals which turn dark when a voltage is applied. For this to work, active-shutter glasses are required to be worn by the user. For example, a dedicate frame is designated for the left eye, while the subsequent frame is meant for the right eye. In other words, the TV's onscreen images are transmitted to the viewer in alternate sequences. Let us begin by providing you with a little insight on the two major 3D technology before we touch on the various pros and cons of owning a 3D set.Įssentially, a large majority of so-called active 3D televisions utilize the alternate-frame sequencing methodology. Whatever happened to the days when TVs were all alike? Why are there different types of glasses accompanying these 3D screens? Can this TV work with other brands' AV equipment? If you find yourself asking similar questions along the way, then this guide is for you. Understanding 3D TV Technology Understanding 3D TVsįor those who are less acquainted with home theater offerings in general, we can imagine how perplexing it is to experience the bevy of 3D televisions out there. ![]()
