For a better optimization of the transflective AM-LCD, a new technology with extra free parameters is inevitable. Our novel transflective AM-LCD with in-cell patterned retarder enables us to optimize further, resulting in a good brightness, contrast ratio, viewing angle and low chromaticity for reflection and transmission at the same time.

Thin retardation layers are developed. The thin films can be applied in- or outside the LCD cell by wet coating techniques. The cell thickness can be reduced considerably since carrier sheets, protective layers and adhesive layers are no longer a necessity. In addition, the optical properties can be patterned on subpixel level which improves the LCD on grey scale inversion, contrast and/or brightness depending on the display type. Photoalignment and thickness patterning are presented as technologies towards patterned optical foils.

Advanced two- and three-dimensional modelling was used to explain microscopic measurements on two different double-domain twisted-nematic liquid-crystal-display (TN-LCD) configurations that were made using photoalignment. The shape of domain walls and their effect on the transmitted intensity were described correctly. For some double-domain configurations, the brightness and contrast of the display will be affected by the domain walls.
