Abstract
An anode driver chip and a cathode driver chip attached to an OLED device by means of anisotropic glue. The fine structure of the attachment means requires inspection to determine any resulting open and short conditions. The anode driver circuits comprise an output current detection that allows open circuit testing of the contact between the OLED device and the anode driver chip. The cathode driver circuits comprise a voltage detection circuit that allows both open and short circuit detection between cathode driver pads.
