Toshiba to Launch World's First 7.7-inch Low-temperature Polysilicon LCD for eBook Devices|
27 September, 2000
Tokyo--Toshiba Corporation today announced commercialization of a 7.7-inch low-temperature polysilicon thin-film transistor (TFT) liquid crystal display (LCD) designed for mid-size electronic books supporting Microsoft's ClearType technology. Developed to meet specifications jointly developed by Microsoft and Toshiba, the new display will enter mass production at the beginning of 2001. Samples will be available from October.
The new low-temperature polysilicon display achieves a resolution of 150 pixels per inch, the same image quality as digital photography. It is optimized to take full advantage of Microsoft's ClearType font display technology, which offers dramatically improved font display resolution that marks a genuine breakthrough in screen readability. The new display delivers an on-screen reading experience that, for the first time, approaches the quality of reading text printed on paper.
Low temperature polysilicon TFT LCDs utilize crystallized silicon. This supports much faster electron flows in transistors than the uncrystallized silicon of mainstream amorphous silicon TFT LCDs, a performance enhancement that supports higher resolution and richer color. Low temperature polysilicon TFT LCDs also offer greater design flexibility than other LCD technologies, as most LCD drivers can be integrated directly on the display panel itself, not around it, the typical design of other displays. As a result, the space required at the periphery of the panel is minimized, the number of components in the LCD module is cut by 40%, and the number of connections between TAB drivers and electrodes on the panel is reduced by 95%. The displays also achieve lower power consumption and higher durability, making them ideal for mobile terminals ranging from notebook PCs to PDAs and eBooks.
The new product will be displayed at CEATEC JAPAN Exhibition 2000, which will be held at Makuhari Messe, Chiba Prefecture, from October 3 to 7.
