Abstract (en)
A flat panel display (100, 362, 400, 450) with a screen (104), apertures (112) in a sheet of material (108) and electron sources (106). A potential difference is established between the screen (104) and the sheet (108). The electron sources (106) are positioned under the numerous apertures (112) which focus the electrons from the sources (106) to different positions on the screen (104). Additional electrodes (325, 350) are positioned in the display to further focus and steer the electrons toward the screen (104). <IMAGE>
