The first Study Session this year was organized by the Technical Sub-committee at the Fun Theater in Headquarters Mirai-Kenkyusho of Namco Bandai Games.
The theme was "The latest trends of 3D displays and the flat panel display technologies which support them".
In this serious global economic slowdown, participation of major companies in the 3D business has started to be come together with the increase of 3D movies in Hollywood which will finally lead to establishment of the 3D market.
In such a situation, we invited experts who are at the forefront to be lecturers at the first study session this year to explain about the trends of ultra-realistic technologies and flat panel display technologies which support ultra-realism and to provide case examples of development of the latest 3D display without glasses.
There were 32 members at the study session for a total of 55 people attending.

The ultra realistic communication technology represented by 3D technologies is expected to be developed as fundamental technology which will support the information culture in the future. In this lecture, future challenges of the "information technology which supports culture" in a broad sense were identified; the lecture also reviewed the direction to be taken by the ultra-realistic technology.

Various applications have evolved for LCDs including displays for small and light weight portable devices, large screen TVs for home use and new high functionality display devices. In the process of the development, numerous advancements have been achieved including wider visual field angles, display of a wider range of colors, higher contrast, higher definition in animation displays, reduction in size and weight, very low power consumption, ultra slim bodies, larger screens, larger capacity for higher efficiency and more advanced functionality. In this lecture, brief explanations were made on the basic actions and start-up method of LCDs, progress and principle of the display and device properties of LCDs associated with realization of 3D displays and their achieving higher efficiency, and recent LCD devices.

The display principle and recent trends of development concerning plasma displays were introduced in this lecture. Some detailed explanations were made on their characteristic graduation display by using subfields. Discussions on their merits including their graduation performance and linearity and introduction of animation displays and 3D displays were also made.
Concerning the recent trends of development, discussions were focused on commitment and results in pursuit of electric power saving in the competition to create more ecological products and of ultimate high definition.

We developed a method to increase image resolution of an autostereoscopic display without increasing the density of micro lenses. Multiple projectors are used for multiple real images to be laid on a surface in the air behind a light deflecting device. The overlaid multiple projection images yield light spots inside the region of a micro lens. This property provides scalable high resolution images by increasing the number of projectors.
Some characteristic aspects of the calibration method that plays a central role in such a projector based display system and the prototype of the display were introduced.

We made trial production of the 18 parallax time-multiplexed 3D display based in the one-dimensional integral imaging principle by using 9-inch OCB LCD. The time-multiplexed 3D display we proposed consists of an OCB LCD, lenticular sheet and an active shutter. In this presentation, two approaches by using the time-multiplexed technology were examined which improved the range of protrusion and the visual field compared to traditional structures; Monte Carlo simulation was used for examination for improvement of lens and active shutter structures and the result which achieved twofold improvement of performance was also explained.
