    摘要: Nematic liquid crystal display device, in which the isocontrast curve has obtained a more symmetrical shape by combining two and four sub-pixels with twist angles which are smaller than 90 degrees, at which the sub-pixels are obtained by providing different orientation directions (11) in an orienting layer (8) by means of linearly polarized light. If a cholesteric nematic liquid crystal material is used, a sub-pixel may have a twist angle of more than 90 degrees, while pairs of sub-pixels then have twist angles of opposite twist sense, at which the sum of the absolute values of the twist angles is smaller than 180 degrees.

    摘要: The present invention provides for improved brightness and reduced power consumption in transflective displays operating in transmissive mode. The invention is based on the inclusion of a depolarizing means (206) between the transflector (201) and the rear stack polarizer (202). The depolarizer (206) is arranged to selectively depolarize light originating from the backlight (203) and reflected by the transflector (201), without substantially affecting the light that is transmitted through the transflector. Thereby part of the reflected light is transmitted back through the rear stack polarizer (202) and can be recycled in the backlight (203). The invention is applicable to any transflective display having a transflector (201) that changes polarization of light originating from the backlight (203) upon reflection back towards the backlight (202).
