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.

Much past 300 ppi is not something the human eye can detect. I wish the 4k idiots would realize that. A capture rate of 120 frames/sec at even 720p (playback also at 120, not 60 frames/sec) would yield what to the human way of seeing was a VASTLY better motion picture experience.

Your very good points are offset by your extreme hostility. Try calming down a bit before you post next time.

I do agree with him, it's not about "PPI" specifically, but there is a point of diminishing returns. PPI is a decent scale to go by, as you have to use some measurement that isnt "it just looks better". Some people cant see much difference beyond 300, and for some its more like the mid 400's, perhaps some are even higher, but beyond the mid 400's, you are really looking at diminishing returns. Very minimal improvement for large effort/cost. I cant see much need for higher than 1080p at 5.5 inches or less. But if they want to build it and people want to buy it, go for it.

So, only "A) the content on the TV and B) the surroundings" are the factors? How about we add:
C) focusing distance of objects
D) stereo vision (for most of us, anyway)
E) temporal construction of depth based on head and eye movement
F, G, H.... ????

I can tell you that your experiment would fail.

And what will I do if you come with more ignorant crap about it? Why? Nothing!

Not ridiculous.

B&W laser printers mostly use 600dpi and magazine covers are typically 1400dpi.

Please remember that since printers are only able to set a pixel to on or off, not 20%, 30%, etc. like an LCD, they need a lot of extra resolution because of the patterns needed to trick the brain into thinking that colors that are, in fact, solid seem to be otherwise through dithering.

With B&W laser of old that were 300dpi, gray scale is atrocious, but pure B&W is quite good.
