New display will vie with LG, Samsung, and others for dominance

While Samsung Electronics Comp., Ltd. (KSC:005930currently dominates 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. (TYO:6753).

Sharp announced 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. (KSC:066570) 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 (AAPL) coveted iPhone, using a slightly smaller display unit.  The company announced in August that it would be shipping displays for the iPhone 5 en masse.  LG announced similar shipments, indicating that Apple would split its demand between the two manufacturers.

A third player is Japan's Toshiba Corp. (TYO:6502), which recently demoed 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.

Wasted Pixels

Smartphone screens are the wrong form-factor to be pushing for increased resolution. At over 300 PPI, we're already at or past the point where the human eye can distinguish the pixels at the distance people actually use their phones. People would have to hold their phones right up to their face to see the increased detail going to full HD with screens in the 4 to 5 inch range. It's a waste of GPU and battery power to push all those pixels for detail that people won't be able to see.

Decreased power usage, superior contrast, black levels, color gamut, higher refresh rates and lower pixel transition times are all much more worthwhile areas for improvement in smart phone screens (and all displays, really) than simply MOAR PIXELS.

Good to see IGZO tech getting rolled out, though.
