Alternate lightening display method for surface-conduction electron-emission display

Alternate Lightening Display Method (ALDM) for surface-conduction electron-emission display (SED) is proposed to help cutting down the panel fabrication cost. Since the landing position of the emitted electrons on the phosphor plate is mainly determined by the polarity of the device voltage and close to the positive voltage electrode, the same dynamic resolution can be obtained by ALDM with only half surface-conduction electron-emitters (SCEs) compared with the conventional panel. The experiment shows six luminescence lines can be generated with three SCE lines. The emitted electron excursion on the phosphor plate is analyzed with a simplified model, and it is in good agreement with the experiment result.

► We study the landing position of emitted electrons on the phosphor plate in SED.
► The landing position is mainly determined by the polarity of the device voltage.
► A simplified model is proposed to analyzed the experimental result.
► The same dynamic resolution can be obtained with half SCE lines.
