Sharp has developed a new 4.1” IGZO LCD display with 736 pixels per inch (ppi). According to Sharp, its new display has the same pixel density as a 6-inch 4K display. The highest-resolution LCD panel that the company has so far developed is a low-temperature polycrystalline silicon (LTPS) panel that has a resolution slightly lower than 550ppi.
The Japanese company has managed to pack in about 4 million pixels into a space just 4.1 inches across. While normal display pixels are around 27µm, Sharp has developed a smaller one at 11µm allowing them to fit more of them into a smaller display array. Sharp believes this panel will see 4K displays in smartphones become a common thing. It must be noted that human eye can only distinguish upto 550 ppi.
The company aims to start volume production of the new panel in 2016, planning to start to ship samples for design-in in 2015.
