Japan Display Inc. Announces Development of 12.1-inch 4K2K TFT LCD Module

October 22, 2013 (Tokyo, Japan): Japan Display Inc. (JDI), a global leader in mobile display technologies, 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 precise and dynamic images within the resolution range of full high-definition (Full-HD) smartphones, with approximately 4 times larger screen size. Low temperature poly silicon technology (LTPS) enables not only high-capacity information content and high-resolution, but also low power consumption, thinner module and narrower dead-band2, which suits mobile-use devices like tablets.

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

That’s higher than 3200 x 1800 used in some Samsung laptops and tablets and has approximately twice as many pixels as used in 13-inch MacBook Pro with Retina Display.

But the more important factor is cost.

I found out that some of the latest Apple MacBook Pro laptops and some 27-inch monitors based on LG’s AH-IPS panel with HDMI 1.4a can display 3840 x 2160 pixels though the readability can be seriously compromised. At least one such monitor costs a little under US$300, but many who bought that monitor seem to regard is quality low to lowest. I’d like to experiment with several AH-IPS monitors that can display 3840 x 2160. HDMI ver. 2.0 will soon be on computer monitors and graphic cards, but 3840 x 2160 @30Hz I think is better than 1920 x 1080 @120Hz or 2560 x 1440 @60Hz.
