1. A display comprising:
a plurality of modules, each of the plurality of modules comprising a light source and a spatial light modulator disposed to modulate light emitted by the light source in response to image data; and, a screen illuminated by the plurality of modules; wherein each of the modules is capable of illuminating a corresponding area of the screen and the areas of the screen illuminated by different ones of the modules overlap with one another; and wherein each of the modules comprises a control circuit that is connected to receive a data signal carrying the image data and is configured to generate a driving signal for the light modulator based upon the image data and is associated with a computer-accessible responsibility map, the responsibility map comprising an image at a resolution that is the same as a resolution of an image to be displayed by the display on the screen, the responsibility map identifying those pixels of the image data for which the module is not responsible and those pixels of the image data for which the module has full or partial responsibility and, for each of those pixels for which the module has partial responsibility, identifying a fractional amount of responsibility of the module for the pixel, the responsibility map further specifying a correlation between pixels of the image to be displayed on the screen and pixels of the spatial light modulator of the module; wherein the control circuits in a plurality of different ones of the modules are connected to receive the same data signal and the control circuit in each of the plurality of different ones of the modules is configured to, using the responsibility map: extract a portion of the image data relevant to the module; map pixels of the extracted portion of the image data to corresponding pixels of the spatial light modulator; and generate the driving signal based upon the extracted portion of the image data and the corresponding amount of responsibility of the module for the pixel; and wherein for each module, intensities of light from the pixels of the light modulator of the module corresponding to pixels of the image data for which the module has partial responsibility, are controllable by the control circuit based on: the fractional amount of responsibility allocated to the module for the pixel by the responsibility map; and the image data corresponding to the corresponding pixel of the image data such that the intensities of light from the pixels of the light modulator of the module are adjusted in proportion to the amount of responsibility of the module for the pixel according to the responsibility map when the amount of responsibility allocated to the module is greater than 0% and less than 100%. |
