The development of 42” 2D/3D switchable display

“…Autostereoscopic displays have been available for some years, but they have generally had low geometrical resolution compared to the resolution in ordinary 2D mode, and the depth range that can be visualized in autosteroscopic mode has been somewhat limited compared to the height and width of the screen area [5,6].…”

“…Some developers of large sized displays are also adopting this technique. The most advanced example is that of the LG Electronics/LG.Philips LCD system, 42-inches size with a 1920x1080 pixel panel 7 . The luminance for the 3D display is 450 cd/m 2 and is 200 cd/m 2 for 2D.…”

The three-dimension (3D) to two-dimension (2D) convertibility of display hardware described in this paper is an essential factor in the commercialization of a 3D display. The liquid crystal (LC), which is a suitable material with its optical anisotropy and electric properties, is widely used for various 3D/2D convertible display techniques. There are three kinds of autostreoscopic 3D/2D convertible techniques -the LC lenticular lens, the LC parallax barrier, and integral imaging. The techniques are on their ways for continuing development and improvement. In this keynote paper we summarize the principle and status of the techniques.

“…Figure 1(a) shows the concept of LC parallax barrier system. Many companies have developed this kind of 3D display systems, among which LG Electronics/ LG.Philips LCD system has the largest size (42 inches) of 3D/2D convertibility with 1920x1080 2D panel [1]. The white/black pattern can be changed, i.e., the barrier can be switched as Fig.…”

This paper explains and compares various threedimensional(3D)-two-dimensional(2D) convertible autostereoscopic and integral imaging display systems. I. IntroductionRecently, researches on 3D display systems are quite active in two categories. One is 3D-2D convertible autostereoscopic (glassless) systems. There are several reasons why convertibility is important. The most important is that a 3D television system that is not convertible to 2D television cannot penetrate into the current display market and so cannot be widely commercialized. Another reason is that, in general, if we want to display 3D images, we need to sacrifice some quality of 2D images, such as image resolution. As a result, the 3D/2D convertible display is proposed as a solution of 3D systems for real market. Regarding the lack of 3D contents and low resolution of current 3D display systems, the concept of the 3D/2D convertible system is to add a 3D display function to a normal 2D display system. In other words, the 3D/2D convertible display is proposed to provide an additional 3D display function to the 2D display system, and aimed for a selectable display of 3D images for specific applications. The other category is 3D display systems with large screens. Conventional 2D display systems like liquid crystal display (LCD) and plasma display panel (PDP) have become quite mature and large panel systems have been commercialized. Therefore 3D display systems have to provide such large size images to catch up with 2D display systems and many research groups reported large screen 3D display systems. Almost all 2D display systems except for mobile device (like cellular phone) applications have become larger in display size to match with the need of the consumers. Hence 3D systems are expected to follow a similar track. In this paper we introduce various 2D-3D convertible autostereoscopic and integral imaging systems. II. 3D-2D convertible systemsHere three kinds of 3D/2D convertible techniques using the LCD technique will be explained and summarized. Some of them are already commercialized and the others are still in the development process. However, each technique has its own advantages and bottlenecks. Liquid crystal (LC) parallax barrier systemsThe LC parallax barrier uses the basic principle of the parallax barrier method. Parallax barrier is one of the simplest autostreoscopic methods and is widely used for many
