Abstract

The invention relates to a multi-view device (100) for generating a first image at a first viewing angle (211) and for generating a second image at a second viewing angle (221) different from the first viewing angle (211). The multi-view device (100) comprises a composite image, an array of elongated optical structures (101) and an Organic Light Emitting Diode device (103). The composite image comprising elongated stripes of sub images (210, 220) comprising the first image and the second image. The array of elongated optical structures (101) is for refracting light (212) of the first image into the first viewing angle (211), and for refracting light (222) of the second image into the second viewing angle (221). The Organic Light Emitting Diode device (103) is for imaging the composite image via the array of elongated optical structures (103). The Organic Light Emitting Diode device (103) is optically coupled to the array of elongated optical structures (103). Using an Organic Light Emitting Diode device (103) which is optically coupled to the array of elongated optical structures (101), the multi-view device (100) is light efficient.
