Toshiba Mobile Display this week announced that it has developed a 6.1" liquid crystal display (LCD) panel that features extreme pixel density of 498 pixels-per-inch (ppi). Even though the display sports resolution that is higher than full HD, it is too small for an advanced tablet, too large for a smartphone and likely too power-hungry for electronic book readers.

Toshiba's "retina quality" screen is 6.1" in diagonal and sports 2560*1600 resolution, 498ppi pixel density, 1000:1 contract ratio as well as 176° viewing angles. This newly-developed high-definition LCD panel is based on Toshiba's processing techniques for forming fine-pitch and high-performance, low-temperature poly-silicon (LTPS) thin-film transistors (TFT) on glass substrates, and other precise fabrication techniques which have been cultivated over the years.
The demand towards high-resolution displays nowadays is pretty evident thanks to availability of HD multimedia content and with the arrival of the iPhone 4 smartphone customers also started to look forward increased pixel density, something that greatly enhances image quality. |
Although the extreme pixel density of 498ppi featured by 6.1" screen from Toshiba is unprecedented (iPhone 4 has screen with 326ppi density), the device itself will barely power popular devices. 6.1" diagonal is too small for a tablet (minimum size viable for tablets is 7"), too large for smartphones (even 5" is too big for a pocket-sized device) and too power hungry for e-book readers (high resolutions and densities mean increased power consumption). As a result, the novelty may remain a proof-of-concept, not a wide-spread product.
Toshiba's new 6.1" display will be exhibited at the FPD International 2011 exhibition, to be held in Pacifico Yokohama from October 26 to 28, 2011.
