<p>A display apparatus for projecting light onto a screen medium to present an image to a user, comprising of a source of illumination that is split into a number of substantially equal sub-beams. Each sub-beam is then directed onto one of an array of individual beam modulation devices. The beam modulation devices are arranged such that their combined output is a composite image, with overlapping sections, formed on a projection screen. By utilising an common illumination source, the size, complexity, cost and mass of the projection system may all be kept to a minimum. The minimisation in size enables the outputs from the different projectors to all be sited closely together, and additionally each output may be sited close to the ideal projector location. This positioning enables a composite image with low seam visibility to be produced by the projection system.</p> |
