Japan Display Starts Mass Production Of 8.9-inch Wide-QXGA LTPS TFT-LCD Modules for Tablets

Japan Display Inc. (JDI) has started shipments of 8.9-inch Wide-QXGA (2,560 x 1,600 pixels) low temperature poly-silicon (LTPS) TFT-LCD modules in September 2013.

A 7.0-inch Wide-UXGA (1,200 x 1,920 pixels) LTPS TFT-LCD module has been in mass production since June, 2013, according to the company.

To date, most conventional tablet devices have employed amorphous silicon (a-Si) TFT-LCD technology, resulting in displays with low pixel density, wide dead-band areas, and high power consumption. According to JDI's design simulation, the LTPS TFT-LCD technology has contributed to 40-50% less power consumption and about 30% narrower dead-band width compared to conventional designs for a-Si TFT-LCDs.



The 7.0-inch Wide-UXGA TFT-LCD has pixel density of 323ppi, and the 8.9-inch Wide-QXGA TFT-LCD is 339ppi. JDI?s in-plane switching (IPS) technology realizes wider viewing angles, a higher contrast ratio and less color shift. The combination of IPS, high-resolution and high brightness of 500cd/m2 contribute to vivid images for small fonts and high quality pictures.

Since there are fewer LCD drivers, JDI's LTPS TFT-LCD technology contributes to 70-80% less power consumption of the LCD driving system than conventional designs for a-Si TFT-LCDs. In addition, JDI claims that its high-transmissive pixel design minimizes also backlight power consumption by approximately 40% less compared to conventional designs for a-Si TFT-LCDs.

The technology is also able to achieve about 30% narrower dead-band width than conventional designs for a-Si TFT-LCDs.
