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 or other active sources of light. In one example, the light emitting source emit pixels of light to a projection lens to project an image represented by the projection lens and a baffle and an aperture stop 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.
