Toshiba Develops World-Class, High-Definition LCD Panel
- 498 Pixels-per-Inch (PPI) Provides Photographic-Quality Images -

Toshiba Mobile Display Co., Ltd. (President: Masahiko Fukakushi) today announced that it has developed a liquid crystal display (LCD) panel that features a world-class, high-definition 498 pixels-per-inch (ppi) image in a direct-view, compact 6.1-inch screen. Despite the small screen size, the display resolution format is 2,560 × 1,600 pixels, a higher resolution than even the full HD resolution format of 1,920 by 1,080 pixels.

In recent years, sophisticated operating systems (OS) have been developed which utilize advanced telecommunication facilities and provide a large-volume, high-throughput communications infrastructure. Based on the capabilities of this enhanced infrastructure there are increasing demands for the display screens of information processing terminals, such as smartphones and tablet-type devices, to display large amounts of information on a single screen for quick processing and operation, and for more realistic screen images, potentially even in 3D.

This newly-developed world-class, high-definition LCD panel is based on our processing techniques for forming fine-pitch and high-performance, low-temperature poly-silicon (LTPS) thin-film transistors (TFT) on glass substrates, and other precise fabrication techniques which have been cultivated over the years. This direct-view LCD panel achieves high-definition images with photographic quality, and although the images are displayed in 2D format, they impart a sense of depth and realism.

This technology will be exhibited at the TMD booth #3601 in the FPD International 2011 exhibition, to be held in Pacifico Yokohama from October 26 to 28, 2011.
