Oppo's New Phone Hits 538 PPI

itwbennett (1594911) writes "Oppo Electronics has taken off the wraps on its first LTE phone, and it packs more technology than most if not all laptops. The Find 7 is a 5.5" phone and is the first to support 2560 x 1440 resolution [538 PPI] (by comparison, the Samsung Galaxy S5 has 441 PPI). 'Another striking and unique feature of the phone is its 2.5GHz quad-core Qualcomm Snapdragon 801 processor,' writes blogger Andy Patrizio. 'This is Qualcomm's first chip to feature its Gobi True 4G LTE World Mode, supporting LTE FDD, LTE TDD, WCDMA, CDMA1x, EV-DO, TD-SCDMA and GSM4. Translation: this phone will work on LTE all over the world.'"

Re: approximately the resolution of an adult eye @

For an adult human, 400-600 is about the limit of what we can detect.

No.

For most average human adults, the limit is about 300 dpi.

Speaking as a graphic designer with over two decades of experience, there is a reason that graphic designers have always targeted a print resolution of 300 dpi for colour images.

How 400-600 entered the conversation is beyond me. The percentage of people who can visually tell the difference between a 300 dpi output and anything higher than that is very, very small. The number of people who can spot the difference at 400+ is not even a consideration for discussion. I'm sure there are some who can but don't even vaguely think that they in any way represent the norm.

Any manufacturer who targets a screen resolution above about 350 or so is just targeting big numbers for the marketing benefit - the average user will never be able to tell the difference.

Doesn't really matter to the argument that because of ink absorption causing blurring, and the fact that most people using phones are doing so at 1/3-1/4 the distance of looking at printed images, that your comparison of PPI on phone screens and image DPI that will be used in high LPI printers really isn't equivalent or analogous at all.
