Abstract:
A method for displaying an image on an addressable matrix, field emission display device having gate electrodes and having luminescent pixels at an anode electrode, the image being specified by video words having least significant bits and most significant bits, comprising:(a) associating the pixels of the display device with corresponding video words;(b) selecting pixels of the display device that are to be illuminated using the least significant bits of the corresponding the video words;(c) exciting the pixels selected during step (b) so that they glow at a first light intensity level;(d) selecting pixels of the display device that are to be illuminated using the most significant bits of the corresponding video words; and(e) exciting the pixels selected during step (d) so that they glow at a second light intensity level that is higher than the first light intensity level,wherein step (e) comprises changing an anode voltage that is applied to the anode electrode.
