LIQUID CRYSTAL DISPLAY WITH IMPROVED FIELD OF VIEW

A liquid crystal display utilizes a dual-domain architecture to improve contrast, gray-scale linearity, and hue-angle performance over field of view. The dual domains can have angles of orientation or partitions which are not directly opposite. Also, the dual domains can employ an angle of twist of...

More Information
Summary:A liquid crystal display utilizes a dual-domain architecture to improve contrast, gray-scale linearity, and hue-angle performance over field of view. The dual domains can have angles of orientation or partitions which are not directly opposite. Also, the dual domains can employ an angle of twist of a value of less than or greater than 90°. By utilizing angles of orientation which are not opposite and angles of twist which are not 90°, the dual-domain structure can compensate for poor contrast, gray-scale linearity, and hue-angle performance. The liquid crystal display can be a twisted nematic liquid crystal display that does not require a multi gap color filter. The display can be a normally white or normally black display for use in avionic applications.
