Since the day of its birth, 3D TV has become the focus of home appliance industry. In 2011, the popularity of 3D TVs has continued and the competition for technology has become more intense. Undoubtedly, naked-eye 3D will be the ideal solution for future 3D. However, naked-eye 3D TV technology is far from mature and costly. It is difficult to achieve market access in the short term. Therefore, in the next three to five years, if people want to watch 3D TVs, they must face such a situation: they must wear glasses. In other words, 3D TVs not only changed the traditional way of viewing, changed the visual habits of the eyes watching TV screens, but also added a pair of 3D glasses to assist viewing.

After the preheating of the market in 2010, 3D TVs in 2011 will become one of the biggest hot spots in the development of the home appliance industry with the gradual maturity and improvement of the conditions of 3D technologies, prices and film sources. In this year, more consumers will wear 3D glasses and sit in their homes to watch the impact of 3D TV images. So, for the 3D TV indispensable accessories - 3D glasses, there are five key words can be roughly summarized its development trend and strengths and weaknesses.

Key words: Do not flash From 3D TV in 2010, a market, 3D glasses flashing phenomenon has been affecting consumers to purchase 3D TV intent, but also many manufacturers to develop new technologies, the main driving force. Traditional shutter-type 3D glasses need to send and receive signals driven by power, glasses continue to blink, the viewer's left and right eyes see different screens quickly switch, in the brain synthesis of 3D images, long-term viewing will lead to dizziness, nausea and other bad reaction. At present, manufacturers adopting shutter technology are actively researching and developing technological improvements. They mainly improve the refresh rate, that is, the speed of blinking, so that the viewer does not feel the flickering when wearing the high-speed flashing shutter glasses.

And the other technology listed at the end of last year - not flash 3D, no flash 3D glasses used to no longer need to quickly open and close the flash to render 3D images, so that the real does not flash. LDD did not flash 3D, which was exhibited by LGD at the 2011 CES exhibition and won the world's first screen flicker certification issued by TUV, an international authoritative certification body. It is understood that TUV is a global authoritative certification body with a history of more than 130 years. It specializes in electronic products, medical devices and other types of products, and whether it has safety and harmfulness, and conducts test experiments and issues certificates according to relevant standard specifications. As a result, no flash 3D was selected as "2011 Best Product" by the CES, indicating that no flash 3D will become the trend for this year's application.

Keywords II: Health Everyone knows that the traditional 3D glasses themselves work with electricity, relying mainly on infrared signal transmitters to synchronously control the left and right lenses of the shutter-type 3D glasses to open and close. This rapid switching of the lens causes the screen to flicker and makes people feel dizzy and uncomfortable. Just as in everyday life, most people understand the radiation of mobile phone signals, and they will consciously stay away from their own heads in the moment of answering the phone. The radiation of 3D glasses is close to the human eye and the brain, and it is hard to avoid worrying. Flash-free 3D glasses no longer need to receive the signal to receive electricity, there is no such concern, health performance is obvious.

Key words three: light and comfortable to watch 3D TV adds a "link" to wear glasses, more or less will make viewers feel uncomfortable, so whether the glasses are light and convenient to use, of course, is an important factor. The built-in power supply and structure of the shutter 3D glasses are relatively complicated and cumbersome. At the same time, watching 3D on the live, the viewing angle of the glasses is more limited, and if a person passes between the viewer and the television, the “blocking” signal will cause the 3D to disappear. The non-flash type 3D glasses are very light in design because they do not have a power supply unit. The overall weight is less than 20 grams. Most of them are significantly lighter than the shutter glasses, and the comfort after wearing is greatly improved. Moreover, it is easy to make jacketed glasses without flash 3D. When you watch 3D, you can directly clip jacketed glasses on your glasses, which will provide more convenient for those who are already wearing glasses. .

Keyword 4: The versatility of generic 3D glasses will also affect the convenience of 3D viewing. The first appearance of shutter-type 3D glasses last year was not very versatile. The brands of 3D TV glasses can only be used exclusively. Current manufacturers are striving for improvement and breakthrough. Flash-free 3D glasses do not involve infrared signal reception, so they are versatile and can be watched without wearing flash-type 3D glasses of various brands, eliminating many unnecessary troubles. In addition, the non-flash 3D mode is the same as the 3D mode of the IMAX theater, so the matching glasses of the non-flash 3D TV can also be brought to the theater to watch 3D movies.

Key words five: Fashion 3D TV will become the popular and fashionable home appliance consumption in the next few years, so whether 3D glasses are fashionable or not is also of particular concern to fashion-conscious people. During the 2011 CES show, NBC, one of the three major TV stations in the United States, reported on the non-flash 3D technology exhibited by LGD. It also mentioned that Oakley, an eyewear brand with a unique style, provided 3D glasses for flashless 3D glasses. Another report said that luxury brands GUCCI also launched 3D glasses, fashion talent can wear as ordinary sunglasses. It can be seen that, with the participation and promotion of fashion brands, 3D glasses will be more emphasis on comfort, practicality and artistry, and will be fashionable.

With the development of 3D TV, more people will pay attention to buying 3D TVs in 2011. It can be expected that this pair of 3D glasses, which are indispensable for watching 3D TVs at the present stage, will also strive to give viewers better feelings with the trend of not flashing, healthy, lightweight, comfortable, universal and fashionable. Therefore, in addition to concern for the quality of 3D TVs, the quality of 3D glasses has become an important part of the public's consideration of selecting 3D TVs.
