Mirasol Display Tech : Qualcomm

아래 기사의 내용(LG와 인텔이 이 기술을 사용할 것이다...)은 사실이 아닐 수 있습니다. 출처를 가 보시면 아시겠지만 This article is incorrect. 라고 기사 앞쪽에 써져 있군요...
암튼 배터리만 키운다고 될 일도 아니고 다양한 분야에서 저전력 기술이 등장해야겠습니다...
매번 느끼는 거지만 정말 알아야 할 것이 많군요... 이놈의 이동단말 분야는...
따라가기도 벅찬데 새로운 기술에 새로운 단말에.. 아씨...

[LG / Intel Phone to use Mirasol reflective display tech. Update:Incorrect.] - 출처 : UMPC Portal

As CPU and chipset power consumption becomes less and less in phoneand MID designs, the power drains of the displays, radio, peripheralsand storage technology become more and more significant. One of thebiggest issues, display backlighting, has been something that many people have been working onfor a long time. In current high-brightness UMPCs and MIDs the screenscan take up to 50% of the total power of the devices, which is exactlythe scenario you’re in when you’re mobile.

LG will be tackling this issue on their Moorestown phone in 2010 byusing a reflective, bi-stable technology from Mirasol Displays, a subsiduary of Qualcomm.It’s complex and vastly different from current backlit screentechnologies but I can summarise by saying that it takes a lot lesspower, provides much more effective outdoor brightness and, due to it’stransflective nature, is easier on the eye. The method used is known asInterferometric MODulation (IMOD.)

Mirasol IMOD Structure

There are some white papers and overviews on the Mirasol websitewhich I have been through to try and get a feel for the power savingsand although there aren’t any real figures given (obviously it dependson the size of the display) my gut feeling here is that in 3-5″ devicesin bright room conditions, it could save 0.5 - 1W which will beextremely significant in the LG device which may only have a 2-3Wprofile.  If you want to get a feel for the technology, take a look atthis PDF which alludes to newspaper reading quality in terms of contrast and reflectivity. There’s also a very good video presentation here which the problems of traditional backlit displays and the ‘on-time’ that I’ve been highlighting recently.

It appears that current Mirasol products are currently quite smallin size and obviously the technology is going to be more expensive sowe might see this used as a secondary or external display (as in thetwo screen Nokia E90 design) but with 12-18 months to go before the product needs to be ready, Mirasol may be able to get a full 800×480 screen out.
