Abstract
The pillar structure according to the invention has a substantially longer surface path length from negative to positive electrodes resist breakdown in a high voltage environment. The processing and assembly methods in this invention permit low-cost manufacturing of high breakdown-voltage, dielectric pillars for the flat panel display.
Claims3
