International ClassG09G 003/36Foreign Application Priority Data1990-09-25 GBAbstractA color sequential liquid crystal display, such as a television display, includes a lattice of selectably settable pixel elements which are time multiplexed addressed and illuminated during addressing to produce sequential red green and blue light outputs in any display period. The addressing of pixel elements in successive frame periods is arranged to occur in opposing directions so as to compensate spatial intensity variation which would otherwise arise from illumination of the pixel elements during the addressing. | |
