Abstract:
1. A method to determine integrity of a connection of driver circuits to an OLED (organic light emitting diode) array, comprising: a) forming a first driver device populated with a plurality of first driver type circuits, or forming the first driver device populated with a plurality of second driver type circuits; b) forming a second driver device populated with a plurality of second driver type circuits, or forming the second driver device populated with a plurality of first driver type circuits; c) attaching said first and said second driver devices to an OLED device; d) testing for open circuits between connection pads of the OLED device and the first and second driver devices, further comprising: e) testing for short circuits between connection pads joining the OLED device and the first and second driver devices, further comprising: f) detecting open circuits in connection pads and detecting short circuits between connection pads by interchanging, which driver type circuit uses voltage detection and which driver type circuit uses current detection, wherein the current detecting circuit integrated in each first driver type circuit is interchanged with the voltage sensor circuit integrated with each second driver type circuit.
