My comment:
(a) 桃園縣龍潭鄉

It sppears that Hsinchu Science Park has many campuses.

(b) El mirasol is a masculin noun in Spanish.

"Mirasol, the spanish name for sunflower, means 'looking at the sun.'”

(c) I went to the official website:
www.mirasoldisplay.com
, which however did not help me to understand the mechanism.

(d) The physics of Marasol display:

Interferometric Modulator (IMOD) Technology Overview. Qualcomm, May 2008 (whitepaper).
http://www.qualcomm.com/common/documents/white_papers/QMT_Technology_Overview_12-07.pdf

You may want to start by taking a look at Figure 1 at page 5 (page number is at the bottom of each page). Each "cavity" can be either on or off, thus "bistable" (the heading in page 3).

bistable
http://en.wikipedia.org/wiki/Bistable
(may refer to "bistability in physics; something that can rest in two states")

At page 5, please take notice the last two sentences, so as to understand how a cavity--and therefore the whole screen, for it is useless to produce ONE cavity of black--produce black color; as well as how full color is generated ("A full-color display is assembled by specially ordering IMOD elements [cavities, that is] reflecting in red, green and blue wavelengths")

Then you may read the text starting with the heading "Reflective Display (Continuous Refresh Type)" (at page 2) whose last sentence is: "So far, most portable devices employing reflective displays are the continuous refresh type."

Read till the end. Take notice of
(i) "Speed" at page 9, and
(ii) "Robustness" at page 11 (comparing this technology with LCD).

(e) Why is a butterfly the logo of Mirasol Display?

(f) Brian Dipert, Display-Technology Advancements: Change Is the Only Constant. Conventional LCDs’ industry dominance might seem insurmountable, but, not too long ago, people were saying the same thing about CRTs. Upstart revolutionary alternatives aspire to ascend to the throne, but LCDs intend to retain the crown. EDN, Dec. 15, 2010.
http://www.edn.com/article/511833-Display_technology_advancements_Change_is_the_only_constant.php

EDN is acronym for Electronics Design, Strategy, News.

Please read
(i) paragraph 4 from the bottom, about OLPC; and
(ii) the last three paragraphs, about Mirasol. Then you will learn the joint venture produces monochrome, and that panel of the new fab (by Qualcomm's wholy-owned subsidiary; no more joint venture) will be color.
