The first bendable 2.5-inch full color display from the makers of the Playstation

Just when I thought that AMOLED is the display of the future, Toshiba and Matsushita seem to have other plans in this field.

According to a press release, Toshiba Matsushita Display Technology Corporation (TMD) has developed a 4.3-inch transflective liquid crystal display (LCD) prototype panel that combines optically compensated bend (OCB) technology.

Apparently, this offers a wide viewing angle and a fast response time, and transflective technology, which assures high viewability in outdoor sunlight environments.

The newly developed module offers similar wide viewing angle and fast response time performance in the transmissive mode as achieved in existing OCB LCD panels, and also offers wide viewing angle and an ultra fast response time (2.4ms) performance in the reflective mode.

A transflective panel combines the advantages of both transmissive and reflective LCDs, and it's achieved by optimizing the optical design of the transmissive and reflective regions found in the subpixel and combining the pixel structure with a highly permeable color filter. This design reduces the panel's power consumption while maintaining high screen legibility under dark ambient lighting conditions, characteristic of transmissive LCDs with built-in backlights, and realizes high screen legibility comparable to reflective LCDs when viewed under an external light source

The newly developed LCD prototype was exhibited in the Toshiba America Electronic Components, Inc. at the SID 2007 International Symposium, Seminar and Exhibition at the Long Beach Convention Center, Long Beach, California, USA, which took place between May 22-24, 2007.

Sony has also succeeded a major technological breakthrough with the first bendable 2.5-inch full color display. On Friday, the company released a video with the display being bended while it shows color images of a bicyclist stuntman and a picturesque lake. You can watch the video here.

LG.Philips and Samsung both made announcements concerning the display technologies. LG.Philips said they had developed their first full-color flexible active matrix organic light emitting diode, or AMOLED, that uses amorphous silicon (a-Si) technology. The 4-inch full-color flexible AMOLED display features 320 x 240 QVGA resolution and can reproduce 16.77 million colors. Apparently, at only 150 ?m in thickness, the display is barely thicker than a human hair.

On the other side, Samsung SDI announced the mass production of its 0.52mm-thick 2.2-inch AMOLED in Q3 2007 on the Korean market.

Judging by the latest breakthroughs and announcements, I wonder if there will be a display war between different technology supporters as it happened with the next generation optical formats HD-DVD and Blu-Ray.
