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.

Printers are a bit different. You need a higher starting resolution because a printer achieves colour variation by decreasing the number of 'pixels'.

For example, if you want 50% grey you would space your black toner particles twice as far apart which inherently reduces your resolution.

This is why an 8 colour inkjet plotter with extra lt.cyan, lt.magenta, lt.grey and dk.grey ink cartridges produces prints that are noticeably improved over a typical 4 colour printer.

From a CAD perspective, when there is a display that can render say a 1mm line and a 1.1mm or 1.2mm wide line at any angle without any stair stepping and without using anti-aliasing and the viewer can visibly see the change in width then I would say the DPI is high enough. 443 dpi (17.5 dpm - dots per mm) is close but you may need up to double that, somewhere between 20-30 dpm I think would do.
