<p>A projection display system comprising an array of light emitting diodes comprising at least first (10a) and second (10b) rows of diodes, the diodes in each row being spaced from each other, the diodes in the second row being offset in a direction parallel to the length of the row relative to the diodes in the first row, a collimator for collimating light emitted from the array of light emitting diodes, a reflector, eg a MEMS mirror, arranged to rotate about an axis, the array of light emitting diodes being positioned so that light emitted from the diodes is directed through the collimator and towards the reflector and then reflected to form a display comprising one or more lines of pixels. Imaging optics being provided for receiving the light reflected from the reflector, and positioned so that the reflector (or at least the axis thereof), lies at the focal plane of the imaging optics so as to provide a telecentric arrangement. The display system may be used in a head up display or a helmet mounted display.</p> |
