SID and I visited this week to report to Los Angeles DisplayWeek chat. I have so far LCD technology is seen, it can create spin polarization switch lenses or interest. First, developers in the three-dimensional representation of the interests of manufacturers, passive polarized stereo glasses, a solution shows interest. One of the most common ways to make glasses, is a free 3D representation of the use of lattice film.

This is a plastic film is consistent with the long angle LCD panel, the cylindrical lens is imaging. This helps to directly observe the 3D model of the eye, but it can distort the image if you want to use the contents of the panel 2D. To solve this problem, researchers are developing the structure of the liquid crystal device, you can in a country, other countries, the optical transparency of the lens. This allows the lens is turned on or off, thus increasing the utility panel. Two-dimensional image distortion is definitely a solution for stereoscopic 3DTV requirements, and the lens is there a way to go. Lens array in the switch to the first product of the year, based mainly Toshiba laptop.

I do not know if this is on display at the SID exhibition, but (I will find out), but a study from the United States and Taiwan, the number of papers for fun. For example, the Kent State University researchers describe a project to create an LC adjustable focus lens. Diffraction and refraction on the design and interpretation of the use discussed. University of Central Florida is a very active use change, including design, electronic switches and the lateral movement of the lens blue liquid crystal lens of several new design projects.

You will hear more about the Blue Phase of credit, because they have very fast switching times, could enable field sequential liquid crystal display. This means that the panel makers can triple the resolution (without spaces color filter matrix) and reduce costs. The university is very active in this area of ​​product marketing 2-3 years it seems. National Chiao Tung University in Taiwan is also very active and show a few design. Polarization switching is another big issue. This concept emphasizes the LG display two years ago by the SID of the process of positive retarders calls. They contribute this year on this report, but it seems to concentrate its efforts in this time most of the patterns of the film barrier (FRP) as the active retarder.

The key of this method has allowed the advantage of active retarders it in full resolution images delivered to each eye and the use of passive polarized glasses in the vertical angle boundaries (FRP provides a semi-eye perspective of the individual restrictions, some vertical resolution.) However, among other groups to the charge. One is the RealD and Samsung LCD, showing the trigger in the SID version of the technology on their own initiative.

We saw on the CES demo of their private suites, we’re pretty impressed. I do not have the opportunity to see the exhibition about it in the SID. Another group is led by LCD technology, very fast (400 Hz Switching) liquid crystal cells developed in both directions. This has been the commercialization of applications for film and design ProAV speed of light polarization switching. Council is using the technology to technology, Seiko Epson LCD panels adjustment of working hours. The polarization control panel is fairly simple equipment. LGD and RealD have a scan method (RealD with 8-band, simultaneous switching and scanning in the line), while the LCD technology uses a single cell.

Commercialization of flat panel displays for the biggest problem is the cost of this additional liquid crystal displays. Obviously, the current TFT-LCD plant is too expensive, so this component, these parties are together, plan the factory production and investment costs to determine if and when it should come to understand the commercial product. Samsung Electronics and RealD not appear to be comfortable and solutions, has announced the end of 2012, 23-inch and 27 inch monitor the delivery of goods, but not say when the 55-inch TV will enter the market. In essence, the industry is 8 must-generation belongs to 11 nitrogen production / station to the polarization panel plant, if the cost LCD-TV market. No one had them?
