  • Organic electroluminescent display panel having a plurality of ramparts formed on the first and second bus electrodes
    Patent number: 6140765
    Abstract: Effective and uniform driving of a large organic EL display panel is formed using a plurality of stripes for each of first electrodes and also for each of second electrodes. These stripes are electrically isolated from each other, which enables each group of pixels defined by a set of orthogonal stripes to be driven separately from the remaining groups of pixels. Efficient fabrication methods devised to construct said display panel are cost effective and suitable for mass production.
