    摘要: The invention relates to a method of providing images on a screen and to an image projection device. The image projection device (10) comprises at least one first set (12) of light-emitting units provided in an array including at least two lines of light-emitting units having at least two light-emitting units each, and a light-displacing unit (36) arranged to displace the light from each light-emitting unit before projection on a screen (16), such that each light-emitting unit provides a tile comprising a line including at least two pixels aligned in one direction on the screen. The light-emitting units are preferably LEDs, and in this way, an efficient display or projector that can be accommodated in a reasonably small space is provided.
