Don't want to come off as a basher of Nanoco because I think it's key they stick around for awhile but calling Wah Hong a "leader" is a bit of a misnomer ..With total revs of only 300 million a year and only a portion of that was optical film I would say you are a ways off from the big boys in the industry

Nitto's R & D expenditure was equal to Wah Hongs total revenues.

Nitto is top five producer ...this is a "world leader"
