Actually, according to the Sharp LCD literature here....  There are three
different pixels (RGB) for each "dot" on the screen, sort of like televisions.

Best thing to do is to contact Hitachi and Sharp (two companies that seem to
be "big" on LCD's - Epson and Optrex, also...)  Look under the Thomas Register
under Displays - Liquid Crystal.  (Available at your local library)
