Sharp has announced that it is working on displays measuring 5 inches diagonally starting last month. These displays will boast of having a High Definition resolution of 1920 x 1080 pixels and 443 pixels per inch.
According to Sharp, this is the highest pixel density on smartphones at present. By comparison, LG has created a 1920 x 1080 full HD display with a pixel density of 440 pixels per inch. Meanwhile, Apple’s Retina display 326 pixels per inch and a resolution of 1136 x 640 pixels. The Liliputing blog also points out that the same resolution is usually found on 40-inch High Definition televisions today. Meanwhile, many smartphones today sport a resolution of 1280 x 768 or something similar that qualifies the display to be labelled as High Definition. For example, the Samsung Galaxy S III has a 4.8 display with a resolution of 1280 x 720 pixels and 306 pixels per inch.
While Sharp announced that the display is targeted at smartphones, they may likewise be used by makers of smartphone-tablet hybrids, such as Samsung, which has created the Galaxy Note 2, and LG, which is responsible for the Optimus Vu. This device category, which is also known as phablets, commonly have displays measuring 5 inches diagonally.
Sharp is optimistic that the new display will bring advantages such as clear and crisp text and maps, as well as more realistic images.
At this point, however, Sharp has not announced which devices will be getting the HD display. Sharp, it may be noted, is currently providing displays for other device manufacturers apart from producing its own smartphones.
Sharp, however, is not the only company that has a 1080p mobile display. Apart from LG, which is working on the aforementioned 443 pixels per inch, the Chinese device maker Oppo also recently announced the Oppo Find5 X990, a 5-inch smartphone with a 1080p display.
Sharp is scheduled to showcase the new product during CEATEC Japan 2012 from October 2 to October 6.
