The 3D TV the next hot trends for that?

update: 9/9/2010 11:30:03 AM


Or announced in 2010 has put put 3D TV, basically all the time segmentation method used. However, the time segmentation method is alleged to exist the following two questions: (1) quality degradation caused by crosstalk; (2) by means of 3D active shutter glasses in cost, security and compatibility of the flash memory in the subject.

3D LCD TVs generally use the 240Hz-driven LCD panel, while in some products, while also using the scanning LED backlight and other improvements to reduce the crosstalk phenomena. However, the 240Hz panel will occur more than 8% cross-talk, even while scanning will occur 5% crosstalk. The idea that, even, is equivalent to 600Hz plasma TV, but also the probability of occurrence of 3% crosstalk.

3D glasses on the safety, because their glasses are equipped with rechargeable batteries and the controller, it will take on the case of the damage occurred, and EMI (electromagnetic interference) and so on response measures. Dominated by large electronics companies in the manufacturing stage, no major problems. However, the market reached expansion phase, by a third party and the low-end Zhizao products manufactured in Leisi emerged, the effectiveness of security countermeasures may be reaching the limit.

3D glasses on the compatibility, in practice there are many restrictions when watching. 3D TV and 3D glasses used for tuning between IR (infrared), because the only straight road of infrared. Currently, Bluetooth is being discussed in other ways, but because of the signal means to change and create the time factor, 3D glasses in the signal can not be compatible. In other words, this year bought glasses (Goggles) To be used in a few years also on the need to support backward compatibility, it will naturally become the main factors increase the cost.

Start the proposals to strengthen PatternedRetarder way

Thus, many LCD panel makers have begun to focus PatternedRetarder way proposal. PatternedRetarder 3D TV as the way to market in 2009 has been mass produced variety of products, but because of the time segmentation method, compared with the cost and quality are inferior, so the market is turning into a recession. In addition, 3D content to CD-ROM, boxed media (PackageMedia) as the center, Blu-ray discs can be included in the 3D full HD content, so the major manufacturers put forward to support full HD 3D time division manner, and this is the gradual decline PatternedRetarder way a major factor.

However, PatternedRetarderFilm (design phase difference film) to improve the supply system, etc., there has been cost reduction trend. In order to build a production system through a great deal of supply, major manufacturers are promoting the improvement of such substrates. ParternedRetarder way in quality performance perspective and there are some restrictions, but also have 3D glasses can be very cheap supply of the advantages.

3D TV in 2011 on the request of direction will be "in the maintenance of 3D image quality on the basis of low price." TV manufacturers plan to expand the 3D TV lineup. However, especially in the 30-inch class screen sizes below, if using 240Hz panel, the cost will be higher, thus the low prices brought by the restrictions. Therefore, consider ParternedRetarder way more and more enterprises.

In addition, the time segmentation method also began efforts to reduce costs. The current development direction is: to improve the image signal or improve their response time LCD panel, thus even lower than 240Hz panel, you can reduce the crosstalk phenomenon is.

The technology and market strategies from 3D TV to inspect and predict future results, will be Aug. 27 at the "8th Workshop TSR 3D display and the status and future projections of business" on release and specific description.
