LG shows off new 538 ppi display for smartphones

LG has announced the launch of a new high-resolution screen designed specifically for smartphones that is a first for the industry. The screen is a Quad Hi Definition 5.5-inch smartphone display with a resolution of 2560x1440.

According to LG, the display is only 1.21 mm thick and will have a minimum bezel of 1.2 mm. Those dimensions make the new screen 12% better compared to the previous 5.2-inch display used on the G2 smartphone it launched last month. The new screen also promises to be significantly brighter with a rating of 430 nits.
The resolution of the screen is a remarkable 538 ppi.

“LG Display, which pioneered the high resolution mobile market with introduction of the world’s first Full HD smartphone panel in 2012, again opens new possibilities with the successful application of QHD technology,” said Dr. Byeong-koo Kim, Vice President and Head of LG Display’s IT and Mobile Development Group. “With this breakthrough, LG Display will continue to raise new standards for mobile resolution and lead the mobile display market.”

The new screen uses a Low Temperature Poly-Silicon (LTPS) substrate. LTPS displays are expected to ship at a record 765 million units in 2014.
Earlier this year, LG showed off a 5” flexible OLED screen that is designed for mobile devices.

Agreed. My 5" 1920x1080 has pixels which only become distinguishable with an aliased black and white transition.

I suppose it would be nice to have a completely smooth line without using anti-aliasing techniques. But, in practice, we're just talking about a lot of extra video processing and memory utilization for very little visual gain.

There really isn't enough information to really say. I agree with everyone else that after 400ppi it's not very useful, but they didn't mention contrast ratio or refresh rates or any other in depth picture stats.

I disagree with everyone else. Good magazines are printed in 720 DPI because it looks better than 360 DPI, and there is no reason why electronic screens should not profit in the same fashion. All that is required is Software which is capable of using the resolution instead of coming with fixed point-size UI-elements and fonts.

Ya, I guess that the best way to put it is that it is about quality to the specific viewer. If you can personally see a difference in quality, its worth it. If your eyes cannot detect it, its not.

My eyes can't so it would be a waste for me.
