News Release: The former Toshiba Mobile Display

October 16, 2006

Production Launched for a High-Luminance, High-Reflectivity Transflective 8.9" LTPS LCD for Notebook PCs.

Toshiba Matsushita Display Technology Co., Ltd. (TMD) has started the mass production of a transflective low-temperature poly-silicon (LTPS) thin film transistor (TFT) liquid crystal display (LCD) which features an 8.9" diagonal wide-format screen, high luminance, high reflectivity, and is also very thin and lightweight, making it ideally suited for tablet or highly-mobile notebook PCs.

This transflective LCD combines the benefits of transmissive and reflective LCDs. A transmissive LCD with a built-in backlight has an advantage: the screen is highly legible in dark ambient lighting. However, it has disadvantages: the power consumption is relatively high and the screen is hard to see in bright ambient lighting. On the other hand, a reflective LCD used under an external light source has different advantages: the power consumption is low and the screen is highly legible in high ambient lighting conditions (such as outdoors). However, it, too, has a disadvantage: the screen is not legible in dark ambient lighting conditions. TMD has developed this 8.9" transflective LCD panel by employing our strategic, core LTPS manufacturing technology, to arrange and optimize the optical design of the transmissive and reflective regions in the subpixel area, combining this pixel structure with a highly permeable color filter. As a result, the panel encompasses the advantages of both transmissive and reflective LCDs, realizing both high transmissivity and reflectivity.

A thin, lightweight, high-efficiency LED backlight, when combined with this transflective panel, achieves a luminance of 200cd/m2, which is the same as that usually achieved by combining a transmissive LCD with a conventional cold cathode fluorescent light (CCFL) backlighting system.

This new transflective display features excellent visibility in both bright and dark ambient lighting conditions. In a dark room, you can turn on the LED backlight, using the display in its transmissive mode, while in bright lighting (outdoors, for example) you can turn off the backlight to use the display in its reflective mode, which reduces power consumption. Altogether, the display is well-suited for mobile applications, due not only to its excellent visibility in a wide range of environments and low power consumption, but also due to its narrow-profile and light-weight construction resulting from use of thin glass and LED backlighting.

TMD supports the evolution of notebook PC performance by continuously adding new products, including the transflective product mentioned above, that are based on LTPS technology and feature thinness, light weight, and low power consumption.

The product will be exhibited at FPD International 2006, to be held at Pacifico Yokohama, Yokohama, Japan, from October 18 to 20, 2006.
