摘要： A normally white twisted nematic (TN) liquid crystal display (LCD) outputs improved viewing characteristics which are defined by high contrast ratios and/or reduced inversion. The display includes a pair of negative tilted retarders located on opposite sides of the liquid crystal layer, each of the tilted retarders including a tilt or incline angle which varies throughout the thickness of the layer. Additionally, one or two negative uniaxial or biaxial retarders are provided. As a result of the particular orientations, alignments, and retardation values described in the different embodiments herein, the display exhibits improved contrast and reduced inversion, often in the same viewing areas. Contrast ratio in the positive vertical viewing zone is especially improved.

摘要： A normally white (NW) twisted nematic liquid crystal display (LCD) outputs improved viewing characteristics which are defined by high contrast ratios and/or reduced inversion. The display includes a pair of negative tilted retarders (#2 and #6) located on one side of the liquid crystal layer (#10), each of the tilted retarders including a tilt or incline angle which varies throughout the thickness of the layer. Additionally, one or two negative uniaxial or biaxial retarders (#4 and #7) are provided on the same side of the liquid crystal layer as the tilted retarders. As a result of the particular orientations, alignments, and retardation values described in the different embodiments, the display exhibits improved contrast and reduced inversion.

The display includes both positive and negative retardation films, the negative films being biaxial and defined by n.sub.x >n.sub.y >n.sub.z in certain embodiments where the "z" direction is substantially perpendicular to the film plane and the "x" and "y" directions are substantially parallel to the film plane. By providing the positive and biaxial negative retarders with specific retardation values and/or ratios, improved viewing characteristics are provided. According to other embodiments, a positive and a negative (uniaxial or biaxial) retarder may be provided on only one side of the liquid crystal layer.

摘要： An edge-lit backlight assembly is provided for backlighting a display. The backlight assembly may include: a light guide having a first segment and a second segment disposed within a common plane; a first light emitting diode disposed along an edge of the first segment of the light guide such that light emitted from the first light emitting diode propagates through the first segment; and a second light emitting diode disposed along an edge of the second segment of the light guide such that light emitted from the second light emitting diode propagates through the second segment. The first segment of the light guide is at least partially optically isolated from the second segment such that light emitted from the first light emitting diode is at least partially blocked from propagating through the second segment.
