3D imaging concept is based on the Parallax barrier technology, reducing the loss of horizontal resolution by sloping arrangement, and furnishing the display with illustration algorithm, so as to achieve the auto-stereoscopic 3D imaging effect. Taiwan players are leading the way in the development of auto-stereoscopic 3D display technology.

With long been professional skills in making polarizer films, Taiwan makers are also experts in the optical development and manufacturing technology. Daxon Technology Inc., for example, is now capable of providing polarizing films for 3D display in various sizes, Jeng said.

With the expertise of polarizer manufacturing, Daxon can now supply specialized films for 3D display from 3.5- to 65inch, and could also apply further optimization for display characteristics or meet different customer demands. "We can adjust both the visual distance of auto-stereoscopic 3D and the quantity of coordinated views.It is technically out of any question," said Collin Hsu, product engineer of optical film business unit, Daxon.

Certain specifications for commercialization are required in order to achieve auto-stereoscopic 3D display. However, obstacles lie ahead of the way in introducing auto-stereoscopic 3D to the market, particularly costs.

"The contemporary market is still beyond evaluation, because huge auto-stereoscopic 3D digital signage isn't provided with standard price in the marketit's too expensive, and only some Japan customers have shown their interests so far," said an engineer from Teco.

Teco has now developed auto-stereoscopic 3D display boards in various sizes, from small digital photo frames to large size products (40-inch and above). Besides, ChiMei and CPT are also joining in the development of auto-stereoscopic 3D display for products varying from PC display to large size TV and digital signage.

Technical bumps
In spite of the great interests for the whole industry in 3D display, this technology is however still confronting with some fundamental challengescontent and video conversion. "2D/3D switchable mode is critical for 3D display," said Jeng. "For example, if you'd like to switch back to 2D from 3D mode, can this display still support this instant switching?"

This has involved numerous packing formats and display formats for 3D content, says Chen of PIDA. Although 2D to 3D conversion software is already available from some manufacturers, this is after all an alternative way during this transition. As predicted by Jeng, it would take at least three to five years to realize the true 2D/3D switchable mode and to have this technology get mature.

On the other hand, continuing supports from variety of standards like blue ray 3D TV, HDMI 1.4 and WHDI 3D HD video etc. shall also promise the success of 3D market; meanwhile, 3D systems with high capacity also requests enough bandwidth to smoothly transmit the 3D signals (e.g. optical fibers).
