Organic EL panel inspection method, organic EL panel survey instrument and organic EL panel

摘要

With simple constitution easily abruptness stop of illumination (the organic EL panel survey instrument in order to carry out inspection with organic EL panel inspection method and the aforementioned organic EL panel inspection method where it can sort the organic EL panel which death) it is easy to do suddenly is offered. At the time of inspecting the aforementioned organic EL panel, in the aforementioned electric current where the organic EL panel well and defective decision consecutively impressing the plural voltage of the value which differs to the organic EL panel, measured respective electric current, when discrimination condition 1 was measured presence of electric current of spike condition, discrimination condition 2 on the other hand consecutively impressing the aforementioned plural voltage from one side of the aforementioned plural voltage on the basis of aforementioned electric current, and when the description above on the one hand consecutively impressing the aforementioned plural voltage from aforementioned another side, presence of occurrence of electric current of the current density which differs at same voltage, discrimination condition 3When impressing the specified voltage of opposite direction to the aforementioned organic EL panel, when absolute value of current density of the electric current which flows, with doing, the description above well and defective decision is done on the basis of the discrimination condition of one or more of 3 from discrimination condition 1.
