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.

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.
