News Release: The former Toshiba Mobile Display

April 16, 2002

Toshiba Matsushita Display Technology develops world's highest resolution 2.2-inch Low Temperature Polysilicon TFT-LCD.
New QVGA displays dedicated to mobile phone application.

Toshiba Matsushita Display Technology Co., Ltd. (TMD) today reinforced its leadership in low temperature polysilicon thin film transistor (LTPS TFT) liquid crystal displays with the announcement of a series of transflective 2.2-inch QVGA (240 x 320 pixels) displays that bring the highest resolution yet achieved to mobile phone displays. TMD plans to bring the new displays to market in the fourth quarter of 2002.

Bringing QVGA resolution to 2.2-inch displays, the size of choice for mobile phones, allows users to enjoy clearer text and significantly improved displays of such images as maps, photographs and content linked with PDA applications. Transflective technology achieves the advantages of both reflective type and transmissive type displays and assures vivid image performance wherever the display is used, whether inside or outside.

A series of cutting-edge innovations allow TMD to reinforce its industry-defining leadership, including system-on-glass (SOG) supporting integration of the LCD driver IC function directly on the display panel itself. This minimizes the space required at the periphery of the panel, cuts the number of components in the LCD module, and reduces the number of connections between driver IC's and electrodes on the panel. Such advances made it possible to achieve QVGA resolution on a display as small space as 2.2 inches.

Another notable achievement is the display's super narrow frame module, which is only 2mm wide on both sides of the display, allowing the display to be integrated into highly compact mobile phone designs.

The new displays are on exhibit at EDF2002;Electronic Display Forum, at Tokyo Big site, Tokyo, Japan from April 16-18,2002.
