Abstract: A display apparatus comprises a light source configured to emit a light beam, a light source driver configured to drive the light source according to pixels of an image frame, a mirror assembly with one or more mirrors configured to oscillate and deflect the light beam according to a scan pattern, a mirror driver configured to drive the mirror assembly according to said scan pattern, a buffer configured to buffer pixels and feed, synchronised by the mirror driver one or more times, the buffered pixels successively to the light source driver, and a central processing unit configured to determine a sequence of pixels of the image frame to be successively displayed according to said scan pattern, and to transfer said sequence to the buffer.

Abstract: A method of generating a pixel stream from an image comprised of pixels which each have a pixel value. The method comprising storing the image in a memory; determining, for each of successive sub-intervals, that pixel that is to be displayed by a light beam within said sub-interval; for each of successive sequences of one or more successive sub-intervals for which the same pixel has been determined: retrieving the pixel value of said pixel from the memory once and appending the retrieved pixel value N times to the pixel stream. Further disclosed is a projection system using this method.

Abstract: A method of generating a compressed data stream from an uncompressed data stream with red, green and blue sub-streams of red, green and blue colour values of an image, comprising, for each of a number of sub-interval which together form a time interval: Determining, in each sub-stream, at least N?1 sets of successive equal colour values and run-lengths indicating the numbers of colour values in the sets; and generating a data packet composed of one colour value from each set and their respective run-lengths; which data packet forms the compressed data stream for said time interval. Further disclosed is a projection system using this method.
