Abstract:
Systems for displaying images in a cinema setting can include components to reduce screen-door effect. The systems can include an array of light emitting sources (102) or other active sources of light. In one example, the light emitting source emit pixels of light to a projection lens (124) to project an image represented by the projection lens and a baffle (150) and an aperture stop (118) can block part of the light from the sources that exceeds an allowable cone angle of acceptable of the system. In another example, a display includes the array of light emitting sources and additional elements, such as diffuser elements, positioned in front of the array of light emitting sources.
