Projektionsdisplay mit Mehrkanaloptik mit nicht kreisförmiger Gesamtaperatur

The invention relates to a projection display equipped with an image generator (30), which is designed to generate individual pictures in a distribution of sub-areas (33-1 to 33-7) of an image generation plane of the image generator (30). The projection display also comprises a multi-channel optical system (40), which is configured to image one associated sub-area (33-1 to 33-7) of the image generator (30) per channel (44-1 to 44-7) in such a way that the images of the individual pictures on a projection surface are joined to form a whole picture (5). At least some channels of the multi-channel optical system (40) are arranged along at least one curve, which is similar to at least one elongated picture feature of the whole picture (5), so that a two-dimensional anisotropic blurring behavior of each pixel is achieved. In this way, a large range of depth of field can be combined with relatively high projection brightness without having to accept losses regarding the focused display of picture features that should be projected with sufficient sharpness
