Abstract:
1. A method of bonding a cover plate over a plurality of OLED devices formed on a surface of a device substrate wherein each one of the plurality of OLED devices includes a pixelated display area and at least one electrical interconnect area, comprising: a) providing the device substrate having the plurality of OLED devices formed on a surface thereof; b) providing the cover plate having disposed on one surface thereof a layer of a pressure-sensitive adhesive material; c) transporting the cover plate in alignment with the device substrate through a pressure roller apparatus so that the layer of the pressure-sensitive material provides uniform bonding between the cover plate and each OLED device on the device substrate, thereby achieving a plurality of packaged OLED devices; and d) singulating the device substrate and the bonded cover plate to provide a plurality of individual and packaged OLED devices having a bonded cover plate and permitting access to at least outermost portions of the at least one electrical interconnect area for attaching electrical leads thereto.
