Japan Display Unveils Low Power 10-Inch 4K Tablet Displays

If you think that the current resolution of high end tablets are already amazing then you haven’t seen what Japan Display (JDI) has in store for the market. This Japanese company which is a global leader in manufacturing small and medium sized displays has just shipped samples of its 10.1-inch liquid crystal display (LCD) module that has a resolution of 3840 x 2160 pixels.

4K2K display

The top tablets in the market today don’t even have this high of a resolution yet. The 9.7-inch Apple iPad only has a resolution of 2048 x 1536 pixels while the 10.1-inch Google Nexus only has a resolution of 2560 x 1600 pixels. JDI calls its latest product as the 4K2K display for tablets.

Last year the company made a 12.1-inch 4K2K LCD module that had a resolution density of 365ppi. This 10.1-inch is even more impressive as it has a higher resolution density of 438ppi. This makes a tablet using this display have as many pixels as a 4K TV set.

JDI explains on how this display was created by saying that “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 WQXGA LCD module based on the amorphous silicon technology , even though it is a high capacity display panel. With the battery running time unchanged, it offers users a 4K2K experience.”

Technical Specifications

  • Display mode: IPS
  • Screen size (diagonal): 10.07-inch (25.58cm)
  • Number of pixels: 3840 (x RGB) x 2160 (4K2K)

What’s probably the main selling point of this latest display is that while it offers a higher resolution it still draws considerably less power compared to present displays with lower resolutions. This means that tablets won’t have their batteries easily drained when using this 4K2K display.

What consumers will have to worry though is the cost of a tablet that uses this type of display. Right now no estimates have been given yet but it will definitely come at a premium price at launch. When there will be more tablet models using this type of display then there’s a big probability that the cost will drop considerably.
