Toshiba 367ppi
Manufacturers compete for highest resolution

19 May 2011 | Rasmus Larsen |

A few days ago Samsung unveiled a 10.1-inch LCD panel with 2560x1600 pixel resolution. But other manufacturers have also exhibited impressive panels at the SID 2011 exhibition, such as Toshiba’s new 720x1280 pixel 4-inch LCD panel and E Inks new 9.7-inch 2400x1650 pixel ePaper panel.

Toshiba 367 ppi LCD panel beats Retina Display

SID 2011 in Los Angeles is all about display technology and all the big manufacturers are lined up to exhibit their most impressive new panels.

Toshiba has one of the most interesting new LCD panels at the exhibition with their all-new 4-inch LCD panel with 720x1280 resolution – or 367 ppi (pixels per inch). That is actually higher than the current Retina Display in Apple’s iPhone 4 that has a pixel density of 326 ppi. The panel also has 1000:1 contrast ratio.

Toshiba plans to mass produce the new panel but they have not announced who the buyer is. However, the panel is clearly aimed at high-end smartphones.

Futhermore, Toshiba exhibited a 3.3-inch LCD panel with 480x864 resolution - or 300 ppi.

E Ink’s 9.7-inch ePaper panel

But not only the LCD panel technology sees improvements in resolution. E Ink and Epson has exhibited a new ePaper panel. ePaper is the type of display that you know from Amazon Kindle and other eBook readers. It has a very matte surface and looks very similar to real paper.

The new 9.68-inch ePaper panel has an impressive 2400x1650 pixel resolution (300 ppi), and we would love to see that resolution in future e-Book reader.

E Ink has developed the ePaper panel and Epson has taken care of the high-speed controller board that is needed.

E Ink has not announced concrete plans to mass produce the new 300 ppi ePaper panel but it is being exhibited at the SID 2011 exhibition in Los Angeles right now.
