While smartphone screen sizes appear to be closing the gap between the mobile phone and tablet, larger handheld devices are further advancing screen technology and Japan Display is looking to add 4K to the mix. The company has announced a new 10.1-inch IPS LCD display with a "4K2K" resolution (3840 x 2160). This would provide a super high-definition experience for tablet owners with a pixel density of 438ppi, comparable to premium smartphones.
The display also features a 160-degree viewing angle (thanks to IPS), a brightness of around 400 nits and a contrast ratio of 1100:1. For those who aren't up to speed with terminology or specifications when it comes to screens, that's not a bad list. This display would enable Windows and Android tablet manufacturers to effectively leapfrog Apple, with the iPad Air sporting a display with a resolution of 2048 x 1536.
It's not known exactly when we'll be able to see this display used in tablets, nor do we know which OEMs (or platforms) will pick this technology up. What we do know is that 4K is coming to tablets, it's simply a question of when. Check the press release below for more details. Would you like to see a 4K 10.1-inch Windows tablet?
JDI announces 4K2K display for tablets
April 23, 2014 (Tokyo, Japan) - Japan Display Inc. (President and CEO: Shuichi Otsuka; JDI), has developed a 10.1-inch liquid crystal display (LCD) module with an ultra-high resolution of 3,840 (horizontal) x 2,160 (vertical) pixels (hereinafter "4K2K") for tablets in a bid to expand the 4K2K experience to the mobile area. It has begun shipping samples.
JDI developed a 12.1-inch 4K2K LCD module (resolution density 365ppi) last year and presented it at the FPD international 2013*1. The new 10.1-inch product is an LCD module with even higher resolution (438ppi).
As the 4K2K format is increasingly used in displays for televisions and camera devices, related image processing technologies and peripheral devices are evolving. Centered on these technologies and devices, the trend towards higher resolution is permeating in the mobile area. The introduction of this product will open the way for high-reality immersive expressions of photos, video content and game content for tablets. JDI will be pioneering the commercialization of 4K2K display modules for mobile devices as next-generation flagship models.
This product incorporates the low-temperature poly silicon (LTPS) technology that has long been cultivated by JDI, to provide low power consumption, low profile and narrow dead-band features. In particular, its power consumption is as low as that of the 10.1-inch WQXGA2 LCD module based on the amorphous silicon technology3, even though it is a high capacity display panel. With the battery running time unchanged, it offers users a 4K2K experience.
In the field of mobile devices, where performance enhancement is accelerating, JDI will be working to satisfy customers' demand with its LTPS technology and production capacity that keeps pace with mobile device innovation.
