New display will vie with LG, Samsung, and others for dominance
While Samsung Electronics Comp., Ltd. (
the thriving smartphone commodity display market, a number of Asian rivals are aiming to unseat the South Korean giant. Among them is Japan's Sharp Corp. (
this week that it would be mass-producing a monstrous 443 ppi (pixels-per-inch) 1920x1080 pixel smartphone screen. The 5-inch screen could appear in devices as early as the holiday season, but will likely show up in greater quantities next year. The new display features a brand new pixel technology dubbed CG-Silicon, which Sharp promises brings smartphone displays in line with their full-size counterparts. Sharp's display likely makes use of the company's new "Igzo" power efficient thin-display tech, as well.
The release marks the latest round in a game of brinksmanship by Japan and South Korea's top display makers. Early this year South Korea's LG Electronics Inc. (
) announced production of a
similar 5-inch 440 ppi unit
, which will likely launch in a similar window. LG calls its display technology "Retina" displays.

Sharp is reportedly looking to displace LG in Apple, Inc.'s (
) coveted iPhone, using a slightly smaller display unit. The company announced in August that it would be
shipping displays for the iPhone 5
announced similar shipments
, indicating that Apple would split its demand between the two manufacturers.
A third player is Japan's Toshiba Corp. (
a 498 ppi 6-inch display. Toshiba's display could be the most impressive of the bunch -- unfortunately it's not yet quite ready for the market.

Your point would be made if you also said a 24" 4k monitor is pointless being that it is geometrically equivalent.
My point is that the difference between 400 dpi to 200 dpi is as big a change on a 5" screen as 200dpi to 100dpi on a 24" screen.
If you can see the difference on a 24" screen, you can see the difference on a 5" screen.
Apparent screen size, for example, is identical between a 24" screen at 4 feet and a 5" screen at 1 foot. Those are the distances where you can no longer "resolve" a pixel on a 1080p display.
Now while you don't normally hold a phone much farther or closer than 1', you definitely sit closer to your 24" display than 4', which means 1080p is woefully underspecced.
To get a similar "quality of life" out of a 24" display, you would need about a 4k monitor.
Are you going to now argue that you cannot visually appreciate a 4k 24" monitor? Because that is the "equivalent" geometry to a 5" 1080p screen which you say is pointless.
Me, as I've directly measured, can clearly see the pixels on a bog standard 1920x1200 24" display and can also clearly appreciate a 3840 x 2160 4k resolution.
