You can (finally) use your cellphone to show Windows screens and documents with the same VGA quality as a desktop or laptop!  But, it could be a while before you see the first devices with that kind of capability.

At the Society for Information Display International Conference and Exhibition (SID 2006) tradeshow in San Francisco, Samsung announced that they have developed a 1.98" panel to achieve VGA resolution and display a total of 307,200 pixels (640x480 pixels) on its screen area.

The amorphous silicon (a-Si) TFT-LCD is the world's first to pack actual VGA resolution on a cellphone-sized 1.98" display.

The LCD is capable of running at a pixel density of 400 pixels per inch (ppi).  That is about ten times the 40 ppi density of a typical 40" HD LCD TV.

400 ppi translates into a picture clarity that can show visual details as small as 63 microns, which is about half the width of a human hair!

The screen also shows up to 16 million colors and can cope with "extremely fast data transmission rates required today," according to Samsung.
