Toshiba Matsushita Display Technology (TMD) has developed a 4.3-inch transflective liquid crystal display (LCD) prototype panel which offers both a wide viewing angle, fast response time and high viewability in outdoor sunlight environments. The display combines the optically compensated bend (OCB) technology and the transflective technology. The combination is a first of its kind in the LCD industry.



TMD has been striving to apply OCB technology into practical applications, due to its potential to enable LCD panels that offer both wide viewing angles and fast response time performance. TMD has created an innovative transflective optical design and driving system that optimizes performance in both the transmissive and reflective subpixel structure, which have different electrode configurations. With this new development, TMD has attained an LCD panel which assures high viewability and high video performance in either mode, transmissive or reflective, while ensuring features such as wide viewing angle and fast response time intrinsic to OCB technology. These features are in increasing demand in mobile applications, which must be easily viewable under a wide range of ambient light conditions. 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.

The new product has good viewability even in direct sunlight. In addition, not only does it offer fast video display performance in ordinary temperature ranges, but also at low temperature ranges, thus accommodating various application environments.

The newly developed LCD prototype will be exhibited in the Toshiba America Electronic Components, Inc. (TAEC) at the SID 2007 International Symposium, Seminar and Exhibition at the Long Beach Convention Center, Long Beach, California, USA, from May 22-24, 2007.
