2.2 inch LCD Display featuring VGA Resolution

i4u writes "Casio announces a LCD display with the world's highest resolution. The 2.2 inch LCD display features VGA resolution. The Casio innovation has 368ppi (pixels per inch). The power consumption and size is the same as with current QVGA (320x240) displays. Meaning current mobile phone models could directly be upgraded with a VGA display. So we could very soon see Mobile phones with VGA resolution on 2.2 inch displays. Samsung had the World's highest resolution with 300ppi in early August. Casio took now the lead. More details in Casio Press-Release (Japanese)."

did you read the article at all?

it says it has the same current draw as QVGA but this one is full VGA.

You can also find out for yourself by doing some simple math: if this is approximately 2.2 inches with a 4:3 ratio it means it's going to be approx. 1.76in wide and 1.32in tall, which means that it has an area of around 2.3 square inches, which means that (at 368ppi, 135424 pixels per square inch) it would have 311475 pixels, which confirms full-VGA resolution (640x480 = 307200) due to probable slight measurement differences (I don't think it's going to be *exactly* 368ppi).

Actually, 300dpi is quite clunky for text, and a number of fonts _cannot_ be adequately represented by it (e.g., Optima or Eras --- Adobe even went to the effort of including two different outlines (one low-res, one high res) for early versions of these until hinting algorithms improved).

~360--400dpi is a watershed value and around there text, even with fairly subtle details starts to look right (Interestingly the NeXTLaserprinter could print in 300 or 400 dpi, and one can _really_ see the difference (says the guy who forgt to change the value once before running out resumes and had to reprint a set 'cause they looked bad).

600dpi is ``good enough'' for most things (and is approaching the ability of office paper to hold a dot faithfully)

At 1200 dpi, things are quite nice, but the human ability to create / render type actually approaches that of a 2540 dpi imagesetter --- see Fred Smeijers' book _Counterpunch_ for technical data and microphotography for details. F.W. Goudy often claimed to be able to distinguish by touch dimensions of ~one one-thousandth of an inch.
