I wouldn't expect brand names to help much. There are already a
number of Asian brands common in the U.S. but virtually nobody knows
that Matsushita means "National",
It doesn't. It means "under the pine tree". National is just a brand name (along with Panasonic) that Matsushita uses.
or that Mitsubishi means (ISTR)
"Three Blade" even with the help of the logo.
Maybe "three diamonds"? I don't know exactly what you call a "bishi", but it's like a baseball game diamond shape. Like a squished square.
Hitachi means something like rising sun, though I'm not sure. It's an old name of a province. And I can't remember what Denso is, but I assume the den is "electricity" like in "dian" in Mandarin.
Samsung is also very well known here (I'm staring at a pair of 19"
Samsung monitors right now) but again, I don't know what the word
means. Though writing this had made me curious enough to look it up
I'm almost certain that "sam" is "three". I think "sung" is "star", but I'm not sure about that one. I used to ask my sister what Sam did at the opera.
