We’ve seen several flagships bust out QHD displays before (like the Nexus 6 above), but Sharp has just announced their new 5.5-inch IGZO panel that can go even higher. How high? Well, Sharp’s new display panel has the equivalent resolution of a 4K UHD TV – that’s 3840 × 2160 resolution for a mind-blowing 806ppi (pixels-per-inch).
In sharp contrast Samsung’s Galaxy S6, LG’s G3 and the Nexus 6 have ppi of 577,538 and 493 respectively. The panel is based off indium gallium zinc oxide, which has a higher electron mobility compared to traditional technology. This means that Sharp can push pixel density over its competitors, though there’s still a question of usabilty – most people can barely see the difference between a full HD and a QHD display, let alone a UHD display that’s squeezed in a panel that’s only 5.5-inches big.
There’s also a question of battery life – UHD equipped phones like the Galaxy Note 4, S6 and the LG G3 use considerably more juice to power their high resolution displays. Regardless of real-life applications, Sharp is going ahead and producing the new displays next year, 2016.
