In 2010, when it became the first year of the launch of 3D TV, the battle for 3D TV technology attracted the attention of all parties with the active shutter and polarized light technology that LG Display first provoked. LG Display has thrown out a high-pitched statement that polarizing “not flash†3D TVs are healthier and directs the “screen flash†issue to the active shutter 3D TV camp. In fact, for the LG Display "not flash" 3D propaganda, the composition of the concept of speculation is large, there is still a lot of controversy in the industry for "do not flash" said, for the LG3D gives a more healthy conclusion is not flash Worth scrutiny. While LG Display boasted that it did not flash 3D, it did not mention the issue of polarizing 3D TV's clarity more than half of normal TV. In addition, LG Display announced the so-called "do not flash" alliance, Hisense, Konka, TCL, Haier and other major manufacturers are not as LG Display said voluntarily promote polarized 3D TV, Changhong is the main push active shutter 3D Leading company in television products. LG Display's various propaganda activities have a "no market to market" taste, which also indirectly affects the consumer's objective perception of 3D TV. In view of this, for the real situation of the polarization technology and active shutter technology level, and the true attitude of the mainstream color TV manufacturers to polarized 3D technology, the author gives an objective explanation in the following text.
Active shutter 3D TVs have higher levels of key performance indicators than polarized 3D TVs Since the implementation of the 2008 flat-panel TV high-definition standard, there have been very clear standards for color TV products, regardless of the type of function, the output of the display device should be As a basic evaluation criterion, the effect, in particular the level of clarity, best reflects the technical maturity and market acceptance of additional functions. The same is true for the hottest 3D TVs nowadays, active shutter technology and polarized light technology can achieve 3D visual effects. However, due to the different imaging principles, the resolution of polarized 3D TVs is halved compared to normal TVs, and it is impossible to display high-definition screens because it is divided into two frames corresponding to the right and left eyes by dividing an entire frame into frames. , which means that it is almost impossible to see high-definition picture quality through polarized 3D TVs, but active shutter 3D TVs do not have such problems, it can guarantee that each picture sent to the left and right eyes is a complete high-definition Screen. In addition, polarizing 3D technology will greatly increase the brightness of the TV, and at the same time reduce the viewing angle to achieve 3D effects. Zhang Subing, deputy director of the Center for Conformity Testing of Digital TV Products of the Ministry of Industry and Information Technology, made such evaluations on two kinds of products: a polarized 3D TV, which was launched at the end of 2010, has a higher cost performance, but it has 3D imaging resolution and 3D stereoscopic effect. Obviously not as active shutter.
Polarized 3D TV "does not flash" concept forced on successful marketing of IPS hard screen laid the LGD's position in the LCD panel industry, has also become one of the reasons for once again force 3D "do not flash" screen, but this time for "no The promotional concept of the "flash" concept was somewhat farfetched. First of all, compared with active shutter technology, what “polarization†3D technology refers to means nothing, and there is not a clear statement and strong data support in LG Display’s up to several pages of explanation report. In the LG Display’s publicly-available "Vision Research Center of the Pacific University" report, they found that their explanation for the "no flash" concept was: "Without flash 3D glasses, flickering - the human eye can not feel". In other words, LGD's promotion of “not flashing†is actually “flickeringâ€, but it is not perceived by the human eye, which means that LGD “does not flash†3D TVs also have “flashing†problems. Then, how does the “flashing†effect? Define it? According to Liu Quanen, senior engineer of the National Quality Supervision and Inspection Center of Radio and TV Products, in general, the refresh rate of the 3D LCD/plasma TV screen must reach 120 Hz or more, which means that the left and right eyes receive images with frequencies above 60 Hz. To ensure that consumers see continuous 3D images without flicker; at present, the liquid crystal/plasma TV screen refresh rate reaches 240Hz, and even reaches 480Hz, basically no visible image flicker phenomenon. At present, Panasonic and Changhong's main shutter active shutter 3D TV refresh rate is as high as 600Hz, Samsung's main active shutter 3D TV refresh rate is also 200Hz; LG Display directly refers to the active shutter 3D TV will cause the flicker resulting in the eye The conclusion of the department's discomfort was insufficient and unscientific. The flicker caused by polarized light and active shutter technology is unperceivable to the human eye. However, for this kind of unreadable flicker, who is hurting the eyes and who cares about the eyes, why should we talk about it?
The author believes that the concept of "not flashing" in the publicity expressed in the concept and the derived conclusions have no conclusive and objective basis, or they are misleading to consumers.
The inconsistency between LG and LGD caliber differs in terms of 3D technology. For the choice of 3D technology, there is no uniform statement between LG TV and LG Display. Li Xianglong, head of home entertainment division of Greater China Region of LG Electronics (China) Co., Ltd., made clear in his media interview in May 2010 that Shutter 3D technology is the mainstream of the market in the future. And that LG TV mainly uses active shutter 3D technology, this standard glasses can achieve the 3D image generation by interactive control and the screen refresh rate consistent left and right glasses closing speed. Ergonomically designed eyes are comfortable to wear for long hours of viewing. These arguments are very different from LG Display's efforts to push polarized 3D technology at the end of 2010. The reasons may be many, but I believe that polarizing 3D TV is cheap or become the biggest incentive for LG to change its face. In domestic terminal stores, LG TV counters are also selling actively shuttered 3D TVs instead of polarized 3D TVs. This phenomenon is like a repeat of the LG Display has sold 32-inch plasma screens to domestic brands, but they are ashamed to sell 32-inch plasma TV scene. At the same time, LG official website shows that among LG's 3D TVs that sell well in overseas markets, high-end products such as Including LX9600, LEX9, LEX8, and LX6500 are all shutter-type 3D. . In fact, domestic brands have a clear technical attitude towards 3D TVs. Six mainstream mainstream TV companies have chosen two kinds of 3D TVs at the same time to market, and will use active shutter 3D TVs as high-end products to promote sales in large and medium-sized cities. In the fourth-tier market, home appliances to the countryside are polarized. However, salespersons who have started to sell polarized 3D using LG screens have also inadvertently revealed that polarized 3D TVs are cheap, but if you want to pursue better 3D effects, you still have to purchase high-end active shutter 3D TVs. In addition, 3D TVs including Sony, Panasonic, Sharp, Samsung, and Changhong have all chosen active shutter technology, which is enough to prove that active shutter 3D technology is a more mature and high-end technology.
