摘要： A display is provided for switching between a narrow or private viewing mode and a wide or public viewing mode. The display comprises a display device which is controlled to provide display of a desired image or sequence of images. This is associated with a liquid crystal device having at least one liquid crystal layer whose molecules are switchable between a first state providing a first angular viewing range and a second state providing a second angular viewing range which is within and smaller than the first angular viewing range. With the molecules in the second state, the device at least partially blocks light propagating towards part of the first angular viewing range outside the second angular viewing range. The or each liquid crystal layer is in contact with at least one alignment surface, the or each of which comprises a uniform non-patterned alignment surface.

摘要： An optical film is provided for use in a light source or display to provide rapid cut-off of illumination with angle. The film comprises a light-transmissive substrate of a material having a reflective index greater than one and having first and second major surfaces. A surface relief is formed on at least one of the major surfaces and includes a mirror structure. The mirror structure comprises a groups of specularly reflective surfaces alternating in at least one direction with groups of transmissive surfaces. The film directs light passing therethrough into a desired angular output range, and light reflected back by the mirror structure is returned to a light source for recycling to enhance display brightness.

摘要： A liquid crystal display device comprises: a layer of a chiral liquid crystal material disposed between first and second substrates; and means for applying a voltage across the liquid crystal layer. A first region of the liquid crystal layer is an active region for display and a second region of the liquid crystal layer is a nucleation region for generating a desired liquid crystal state in the first region when a voltage is applied across the liquid crystal layer. The ratio of the thickness d of the liquid crystal layer to the pitch p of the liquid crystal material has a first value (d/p)A in the first region of the liquid crystal layer and has a second value (d/p)N different from the first value in the second region of the liquid crystal layer. The value (d/p)N of the ratio of the thickness d of the liquid crystal layer to the pitch p of the liquid crystal material in the second region of the liquid crystal layer is selected such that, when no voltage is applied across the liquid crystal layer, the liquid crystal state stable in the second region of the liquid crystal layer is topologically equivalent to the desired liquid crystal state.

摘要： A display includes a display device having a first polarizer and a second polarizer or a reflector, and a display layer disposed between the first polarizer and the second polarizer or the reflector. A liquid crystal layer is disposed between the display layer and one of the first polarizer and the second polarizer or reflector. The liquid crystal molecules of at least one region of the liquid crystal layer are switchable between a first state in which the display has a first display mode with a first viewing angle range and a second state in which the display has a second display mode having a second viewing angle range smaller than the first viewing angle range. In the second state, liquid crystal molecules of the at least one region are tilted with respect to the normal axis of the display over at least a portion of the thickness of the liquid crystal layer, and lie substantially parallel to a plane defined by the normal axis of the display and the transmission axis or absorption axis of the first polarizer or one of the first and second polarizers.
