Display apparatus

A display apparatus, comprising:

• 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 to be displayed on an image area within a frame duration;
• a mirror assembly with one or more mirrors configured to oscillate and deflect the light beam towards the image area according to a scan pattern;
• a mirror driver configured to drive the mirror assembly according to said scan pattern;
• a buffer connected to the light source driver and the mirror driver and configured to buffer pixels of the image frame and to feed, synchronised by the mirror driver one or more times per frame duration starting from an initial position within the scan pattern, the buffered pixels successively to the light source driver for displaying;
• and
• a central processing unit connected to the buffer and configured to hold the image frame in a memory, to determine a sequence of pixels of the image frame to be successively displayed according to said scan pattern starting from said initial position, and to transfer said sequence of pixels in one or more successive segments to the buffer for buffering,
• wherein the central processing unit is configured to store a look-up table of indices of the pixels to be successively displayed according to said scan pattern and to determine the sequence of pixels by retrieving the pixels according to the look-up table from the memory,
• wherein the light beam has at least two colours and each pixel comprises a colour value for each of said colours, wherein the light beam is comprised of mutually spaced parallel partial light beams each of a respective one of said colours, and wherein the central processing unit is configured to establish, for each of said colours, a respective offset of the indices of the pixels to be displayed by the partial light beam of that colour from the indices of the look-up table, to write, into each pixel of the image frame, a respective colour value of those pixels of the image frame whose indices are offset by the respective offset from an index of that pixel, and to retrieve the pixels according to the look-up table from the memory.
