Japan Display has developed a 12.1-inch 4K2K TFT module, the world's highest resolution density (365ppi) display designed for tablet use. The display allows users to enjoy images within the resolution range of full high-definition (Full-HD) smartphones, with approximately 4 times larger screen size. JDI claims that low temperature poly silicon technology (LTPS) enables high-capacity information content and high-resolution, but also low power consumption, thinner module and narrower dead-band, which suits mobile-use devices like tablets.



Japan Display will exhibit these displays on October 23 to 25, 2013, during FPD International 2013 in Pacifico Yokohama, Japan.

Japan Display also today announced that it will establish a new subsidiary in Taiwan in order to strengthen its presence in the rapidly growing market of China. JDI believes that this is a landmark milestone that represents further strengthening of the relationship between Japan and Taiwan in the small- and medium-sized display industry.

The new company will be offering semi-customized, middle-range displays, which are currently experiencing rapid growth in demand in China, in addition to the high-end displays that have been JDI's main product category.

The new company (Taiwan Display Inc.) is going to start its business by end of 2013.
