3 Electro-optical Performance of Supertwisted Nematic Displays [Pg.213]

According to Scheffer and Nehring the transmission spectra of the nonselected and select states of the yellow mode and the complementary blue mode for twist angles 0=210° and 0=270° show the following characteristics [17] [Pg.213]
