Not happy with a 5 inch full HD phone, try one with a 6 inch 2560 x 1600 display!
At the high end of the Android smartphone market, this year has been about devices with five inch, full HD (1920 x 1080) displays. But display manufacturers aren’t stopping there. According to industry insiders the key Korean and Japanese display makers are working on six inch WQXGA (2560 x 1600) mobile LCD panels.
To do that the manufacturers are looking to use a process called Low Temperature Poly Silicon (LTPS) to make the displays. With LTPS lasers are used as part of the heat treatment. The result is that very high resolution displays can be made. To achieve the increased resolution and greater PPI, LG Display is working with AH-IPS (Advanced high performance-In plane switching) so it can make panels over 500 ppi.
With five inch HD panels in full production, Samsung and LG are considering using panels made in Japan in order to diversify their supply lines. As a results Japan Display (JDI) and Sharp are also working on 500 ppi mobile displays.
This move to greater than HD isn’t just fueled by a desire for bigger and better. According to recent market surveys, smartphone users under 30 are able to distinguish between 400 ppi and 500 ppi displays.
Unlike the resolution of 1920 x 1080 pixels used on full HD display, Wide Quad Extended Graphics Array (WQXGA) has a 16:10 aspect ratio. It is also the resolution used on the Google’s Nexus 10, but due to its size that display panel is only 300 ppi.
