Abstract
Official abstract text for this publication.
A device for inspecting an organic light-emitting display apparatus includes a power supply unit, a power receiving unit, a wiring location sensing unit, and a control unit. The power supply unit applies an AC signal to each of wirings arranged in the organic light-emitting display apparatus. The power receiving unit senses an electrical signal from each of the wirings. The wiring location sensing unit senses a location of each of the wirings. The control unit determines whether each of the wirings has a defect based on the sensed electrical signal and information pertaining to each wiring type of the wirings.
First claim
Opening claim text (preview).
What is claimed is: 1 . A device for inspecting an organic light-emitting display apparatus having a plurality of wirings, wherein each of the plurality of wirings has a particular wiring type, the device comprising: a power supply unit configured to apply an alternating current (AC) signal to each of the plurality of wirings arranged in the organic light-emitting display apparatus; a power receiving unit configured to sense an electrical signal generated by transmitting the A…
