Japan Display unveils a 5.4-inch 1440p display for smartphones
Apple's Retina display packs 326 pixels per inch while the iPhone's screen with 4 inches and 1,136X640 pixels is widely regarded as one of the best currently available in the 4-4.3 inch size range. Unfortunately for the Cupertino company this could change soon, since Japan Display has just completed a next-gen 4k display with a density of over 500 pixels per inch and a size of only 5.4 inches. Obviously, the next step would be to release even smaller displays using the same technology.
The 5.4-inch display announced by Japan Display has the following characteristics - 1,440X2,560 pixels and 543 ppi, 70 percent NTSC color gamut, 1,500:1 typical contrast ratio, 160 degrees or more viewing angle, being only 0.04 inches thin.
The joint display venture also revealed a 6.2-inch 1440p display, but with "only" 473 ppi. The remaining specs are similar to the 5.4-inch screen - 70 percent NTSC color gamut, 1,000:1 typical contrast ratio, 160 degrees or more viewing angle, 0.065 inches thick.
Unfortunately, nothing is known about the availability and price of these new screens, but most chances are they will first be used in some limited edition devices for the Asian market only.
