Abstract
PURPOSE: To convert defective goods disused into non-defective goods, by restoring the short circuit failure, through blowing out or burning out the short circuit part with high voltage applied to the short circuit failure part of the display unit.
CONSTITUTION: The short circuit failure of the display unit, for example, fluorescent display tuues is the case of short circuit anode segment due to drop print paste at the formation of the anode segment 4 and dirt attachment etc., and the case of short circuit wiring 2 on the substrate 1 with the anode segment 4 due to thin insulation layer 3 and air bubbles. At this time, the failure part is detected by testing the display unit for illumination test, and the short circuit part is molten or burned out by applying the leads to the failure part with comparatively lower voltage to the low resistance short circuit due to conductive paste drop and with comparatively greater voltage to the high resistance value failure due to attachment of dirt after inserting current limiting series resistor. The power supply can be any of DC, AC and pulses.
