As soon as Toshiba announced its 6.1-inch Liquid crystal display (LCD) panel last week, bloggers and tech news sites were noting the numbers and poking at mobile display monarchs Apple. Toshiba’s new display packs a 2560×1600 resolution with a 1000:1 contrast ratio. The display works out to 498 pixels per inch (ppi).
“Astounding,” “staggering,” and “Prepare to have your eyes melted,” were some of the reactions. Reports hastened to compare display numbers with those from Apple.
Suddenly Apple’s “retina display” iPhone 4/4S smartphones of 326 ppi was a less exciting feat. Adjectives like “razor sharp” were usurped from Apple’s gate and replanted at Toshiba’s. Among other bragging points is the fact that Toshiba’s display can show 16.7 million different colors. Toshiba describes the display technology as based on processing techniques with low-temperature poly-silicon (LTPS) thin-film transistors (TFT) on glass substrates and other fabrication techniques that Toshiba has cultivated over the years.
Toshiba credits its LTPS technology as the enabler of advancements like the new LCD display. Low temperature poly silicon makes possible higher pixel density, which in turn makes text and images more readable. That’s especially useful in smaller device screens like handhelds and portable diagnostic equipment, as well as for larger screens, says Toshiba.
