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. |
