2.9" and 800x480 to boot
Mobile web browsers rejoice as
Hitachi has started mass producing its newest LCD mobile phone display according to Japanese site
. The new LCD is 2.9 inches and sports the highest resolution ever found on a mobile phone display—800x480.
The added resolution will allow users to browse mobile web pages easier without having to scrolling side-to-side for less phone friendly web pages. However, the real payoff for such displays is the ability to play 480i content with menus.
The bump to 800x480 is a fairly large pixel increase from the current QVGA (320x240) screens found on most new phones and a moderate increase from VGA (640x480) screens used in some PDA phones.
The new 2.9” LCD uses IPS LCD technology instead of TN typically used in mobile displays today. The advantages of IPS over TN are wider viewing angles, better color reproduction and faster response times. This results in a 170 degree vertical and horizontal viewing angle and a 400:1 contrast ratio. Hitachi owns the rights to IPS technology, but most LG.Philips LCD panels use some derivative of the technology for desktop displays.
There’s no mention when and which phone manufacturers will release products based on the new display.

I totally agree with you on this one. We all watched as phones got smaller and smaller with all the great hype over how they came to fit in your pocket and were super lightweight etc. Then when they got as small as they could go (too small for many trying to use some keypads got near impossible) all the companies moved focus to pack more & more features into each phone. Then came broadband digital and that really is great (if still expensive) and now the features have improved even more with fast internet and video capabilities on every phone.
But the kicker now is that the human body doesnt change, so for video & visuals we always want the biggest, best resolution screen, which goes directly against 20 plus years of mobile cellular technology making them all small as hell; they are having to make them bigger and bigger again, even if many are still pretty light weight. Bit of a catch 22 for phone makers isnt it. I can make you a phone that can store multi-gigabyte movies, but how to make them really watchable?
I think the answer will come via two possible additions. The first is a simple projection option - where the phone can dump a screen (on a wall etc in high res), and the second would be add on eyepieces in the same way you have ear pieces. This isnt immediate mass-market stuff but logic says they must all be looking at the various options to make a killing in the personal mobile market. Personally I dont see screens on the actual phones/devices as the long term answer. They have been fine up until now, but the new visual demands on making a personal communicator have one major unchangeable restriction; us.
