In 2010 January, Manchester United and Arsenal, British Sky Sports Channel for the first time in the history of the game using 3D technology for television broadcast.
The disputed two 3D technologies
At present in the 3D television field, the most popular 3D technology can be divided into flash ( Patterned Retarder ) technology and a shutter type ( Shutter Glass ) technology. The shutter type technology, the 3D imaging is: through the left and right side lenses fast switching, presented by turns around the side of television picture image, presenting side image, another side of the glasses off, making the signal cannot enter the eyes. The use of shutter type technical disadvantage: glasses weight, activity does not freely, expensive, bad eyesight. In addition, since the shutter type of image with large scintillation phenomenon, may cause headaches, dizziness, or even a photosensitive epilepsy.
No flash type 3D technology working principle is the use of film or glasses way through polarized lenses will impact of television to produce a two image, respectively the left and right eyes, and then signal images were transmitted to the viewer's left eye, the final synthesis of two images, thereby creating a total of 3D image. In addition, because the clamping function, no flash technology allows users to not be shutter glasses limited technology, implementation and user of prescription glasses matching. Both the technical principle is different, also caused by two kinds of technology corresponding 3D glasses weight differences, FPR glasses weight less than 15g, and shutter glasses in about 35g technology. More important is FPR technology than the shutter glasses glasses 5 times cheaper technology. The shutter glasses retail price of around $100, while FPR glasses as long as 10-20 dollars, low price can let more consumers to experience the 3D effect.
But not the flashing technology also exist certain defects, mainly polarizing effect of lens to fit into the LCD module will make the high cost, which become the main factors to limit its spread. Based on the shortcomings, in PR (Patterned Retarder ) technology based on Display, LG and R & D FPR ( Film Patterned Retarder ) technology to replace the lens film, allegedly cost will be reduced three fourths, in order to achieve price competitive. Thus, no flash technology and shutter technology competition into the white-hot stage.
LG Display Limited is a thin film transistor liquid crystal display ( TFT-LCD ) panel and a leading manufacturer and supplier of flexible display. The company president Mr Quan Shou said:" FPR3D is through in-depth study of people watching the 3D TV, most those characteristics and the birth of." It is reported, LG Display LCD module plant in Guangzhou in 4 at the end of the cumulative production has more than 100000000, Guangzhou LG Display LCD module plant general manager Jin Linzhu said:" China is developing to become the world's largest LCD ( LCD) market."
According to the ISO certification body TUV research, 90% watch shutter type technology image viewer encountered the flicker problem ( in the shutter type technology, when the movable glasses and by naked eyes to the screen will flicker ). Japan 3DConsortium released 3D safety guidelines, warned:" the flicker phenomenon ... May lead to a photosensitive epilepsy", while blinking or lead to eye fatigue is the main reason. Shutter type technology generally produce 2000 times more flicker frequency, but not flash 3D technology can achieve flicker-free, thereby protecting the audience 's vision health, bring more excellent 3D experience.
Review in recent years, liquid crystal display ( LCD ) market beyond the CRT Market
In early January of this year 's CES show, the wave of 3D cyclone have emerged, including Toshiba, Samsung, Sony and other manufacturers booth appeared on 3D tv. Since April, Samsung, LG and Sony, sharp, the abroad such as the color television enterprise leading, with TCL, Skyworth, homebred color television enterprise 3D market followed, after a huge media campaign, 3D market warms up quickly, 3D television concept also gradually make known to every family. But is restricted to the higher price, 3D source deficiency and other factors, it seems, some" in power do not score points".
Back, even some people assert that in the future 5 years is still in CRT TV in the world. But the voice just fell, liquid crystal TV began rapid development, either technical or market acceptance, LCD TV has been criticized by the visual angle is small, slow response speed, brightness is low blemish being overcome, cost is also greatly reduced, since the beginning of 2004 price falls every year not less than 35%. Until 2009, all beyond the CRT TV LCD TV sales. Over the nearly hundred years CRT TV finally gone.
The electrical manufacturers to unwilling to lag behind
Uncorrected 3D on TV applications are not realistic, as one of the most basic requirement is that many people to watch, and many people watch the inevitable cause everybody with TV screen angle is different, so the available technical support, difficult to achieve each person can have a perfect 3D experience.
Samsung and LG is two 3D display technology represents manufacturers, the same day launched on behalf of their technology 3D TV product, also make the competition between them more dramatic. Then, Japanese also unwillings to lag behind, the rapid selection of camp, Sony released in March the shutter type 3D TV products, let the shutter technology is a member.
In addition to foreign television manufacturers, in the 3D revolution including Konka, Skyworth, Changhong, TCL, domestic enterprises do not go too slow, although experienced LED the throes of transition period, but by the Guangzhou Asian Games on the 3D television brought public opinion boom, move in succession launched its most new 3D TV products. Compared with foreign manufacturers of the camp is trenchant, advocating the doctrine of Chinese attempts to two tactics to catch, although such as Konka, Skyworth, Changhong, TCL, Hisense brand seems to join not flash 's camp, but did not give up the shutter technology 3D tv. TCL 300 new 3D Internet TV already in Asian Games venues, and in Beijing, Shanghai, Shenzhen, Guangzhou, 3D TV tour experience activities. Rainbow also expressed from now until next year first half of the year and then launched three series of nearly 10 3D television products. Konka launched 4 series of more than 20 3D smart TV new. Chuangwei very opens the intelligent 3D series new flagship products have also been interview.
No flash technology in the field of television still occupy a certain advantage, but the two technologies are far from fully mature, if able to capture new difficulties, winning or losing is still unknown.
