Microsoft seems to be betting that screen technology in the next few years will be migrating to AMOLED technology. This is why the new Windows Phone 7 Series device sport a very black looking UI as AMOLED screen use less power showing black thus better battery life. This power advantage comes from the screen not using as much power when displaying black areas of the screen. Kinda the same way a light bulb uses less powere when it is off…

However it seems that Office users users will not enjoy this battery life savings as the email display be default had a white background. This is presumably due to the improved readability of back on a white background as opposed to white on a black background.

Picture says it all really… Excellent black contrast even at a shallow viewing angle.

Just wish that even OLED devices like the Zune HD were available in Australia. Will be interesting to see if there are any Windows Phone 7 devices with AMOLED screens at Mobile World Conference next week.
