Qualcomm Showcases The High Resolution Mirasol Display
We have been hearing rumors on the MEMS-based Mirasol display to be released by Qualcomm. It was claimed to be a sophisticated e-reading platform and the company finally showcases the proof of concept. Some online sources have snagged a preview of the impressive 5.2” panel, sporting 2560 x 1440 resolution, which yields 577ppi of pixel density.
Like Sharp’s IGZO, the Mirasol is also touted for its low energy requirement, about six times lower than OLED and LCD models. Thanks to the MEMS (micro-electro-mechanical system) technology, users will be able to obtain paper-like readability despite the significantly reduced power usages.
There are three subpixels for each of Mirasol pixel: red, green and blue. Like the E-ink, Mirasol also has bistable characteristics, open and closed. Power is needed only needed when the display switches between states. With fast switching rate, Mirasol display can easily do video. There’s one caveat though, Mirasol-equipped display still need external light sources, such as LED to illuminate any images shown.
