Abstract: The present invention relates to a digital display plotter for plotting images on a digital display device 18. A cursive imagery generator 12 generates imagery inputs at a plurality of respective update phases during a refresh period of the display device. A control 20 for the display device activates selected pixels of the digital display device in response to respective said imagery inputs, activation being controlled subsequent to each update phase during a refresh period. An input store 14, 16 associates each cursively generated imagery input with an update phase that the imagery input was generated during a refresh period. The control 20 is responsive to the input store and configured to deactivate the selected pixels activated in response to each imagery input dependent on the associated update phase of each imagery input.

Abstract: A display apparatus (20) includes an electromagnetic radiation source (22) and digital micro-mirror device (21) having a plurality of micro-mirror elements on a surface thereof. The electromagnetic radiation source (22) is arranged to illuminate the digital micro-mirror device (21) and at least one micro-mirror element of the digital micro-mirror device (21) either reflects electromagnetic radiation along a primary path (23) to an exit lens (23) to form a desired image to be viewed by an operator or along a secondary path (25) to an electromagnetic radiation dump (26). The digital micro-mirror device (21) is also operable to generate a test image at the electromagnetic radiation dump (26) at a predetermined time.
