Display

A backlit display comprising:

• a backlight having light emitting regions and non-emitting regions;
• a modulator, arranged to receive light emitted from the backlight;
• light redirecting means, arranged to redirect a portion of the light emitted from the light emitting regions of the backlight onto areas of the modulator in closest relationship to the non-emitting regions of the backlight.

A display comprising:

• a plurality of image guides, each image guide comprising a plurality of light transmission guides having an input and an output end, and a base frame having a coefficient of thermal expansion substantially matching that of the light transmission guides, the base frame surrounding the input ends of the light transmission guides;
• means for coupling the plurality of image guides into an array in which the output surfaces of the image guides form a continuous surface;
• a supporting frame, the supporting frame having greater rigidity than the base frames, and a different coefficient of thermal expansion to the base frames, the base frames being coupled to the supporting frame by a connecting means allowing relative movement between the base frames and the supporting frame in a plane substantially parallel to the output surfaces of the image guides.

A display comprising:

• a display device having an image output surface at which an image is displayed as a spaced array of pixel elements;
• an image guide coupled to the image output surface of the display device and comprising a plurality of light transmission guides each having an input end and an output end, the input ends of the light transmission guides being arranged relative to one another so that groups of one or more light transmission guides receive light from respective groups of one or more pixel elements;
• in which electrically conductive material is provided between and along at least a portion of the length of at least a subset of the light transmission guides, the electrically conductive material being arranged to absorb electromagnetic radiation emitted from the display device, the electrically conductive material between light transmission guides in separate regions of the image guide being electrically connected together.

A tiled display, comprising:

• a plurality of display panels formed into a plurality of rows and arranged to form a single image output surface, each display operable to display a plurality of lines of pixels;
• display control means, arranged to refresh each display panel on a line by line basis in accordance with a refresh pattern;
• in which the refresh pattern for pairs of vertically adjacent display panels are such that a lower region of an upper display panel of the pair is refreshed at substantially the same time as an upper region of a lower display panel of the pair.
