Japan Display this week unveiled a panel with a frankly silly 1440 x 2560 resolution (referred to as Quad HD (QHD), Widescreen Quad HD (WQHD) or 1440p), coming soon to 5.4in and 6.2in devices.
In either case, that’s 3.7 million pixels in the palm of your hand, and way beyond the proposed 300 PPI (Pixels Per Inch) cut-off.
A few years ago, the late Steve Jobs suggested that anything beyond 300 PPI was ultimately imperceivable to the human eye, while others reckon 720p is more than enough for mobile phones.
Still, that hasn’t stopped the industry moving forward with an avalanche of eye-melting devices. The HTC One, par exemple, has a 1080p resolution on a 4.7in display, yielding a PPI score of 469.
This new Japan Display panel will score a PPI rating of 543 and 473 across 5.4in and 6.2in displays respectively. Obviously the bigger the display, the less pixels you have per inch.
Similarly, a device called the Vivo Xplay3S has been teased from out east, with a 5.5in display and 2560 x 1440 resolution. That’d be 534 PPI. Crazy.
How do you feel about the recent advances in mobile displays? Waste of time, resources and money, or will you settle for nothing less than 1080p?
