Dual-type organic electroluminescence display and manufacturing method thereof

A dual-type organic electroluminescence (EL) display comprising:

• a main organic EL device comprising:
• a main substrate,
• strip-shaped main substrate scan lines,
• a main substrate organic light-emitting portion, and
• main substrate data lines formed on the main substrate;
• a sub organic EL device opposite to and facing the main organic EL device, comprising:
• a sub substrate,
• strip-shaped sub substrate scan lines,
• a sub substrate organic light-emitting portion, and
• sub substrate data lines formed on the sub substrate;
• a sealant comprising a conductive spacer, sealing the main and sub substrates and hermetically sealing the main and sub substrate organic light-emitting portions in a state in which the main and sub organic EL devices face each other;
• floating electrode lines formed on the main or sub substrate and connected to electrode lines on the remaining main or sub substrate;
• and
• at least one flexible printed cable (FPC) connected to the main and/or sub substrate;
• wherein a plurality of the electrode lines on the main and sub substrates are electrically connected to each other by the conductive spacer.

A method of manufacturing a dual-type organic EL display comprising:

• preparing a main organic EL device by forming main substrate scan lines, a main substrate insulating layer, a main substrate organic layer, and main substrate data lines crossing the main substrate scan lines on a transparent main substrate;
• preparing a sub organic EL device by forming sub substrate scan lines, a sub substrate insulating layer, a sub substrate organic layer, and sub substrate data lines crossing the sub substrate scan lines on a transparent sub substrate;
• aging the main and sub organic EL devices;
• sealing along the periphery of an effective display area to hermetically seal the main and sub organic EL devices so as not to be exposed outside, wherein the sealant comprises a conductive spacer;
• and
• connecting flexible printed cables (FPCs) transmitting a drive signal to at least one of the main and sub substrate scan lines and/or at least one of the main and sub substrate data lines electrically connected to each other by the sealant.

A dual-type organic electroluminescence (EL) display comprising:

• a main organic EL device with a first light-emitting portion;
• a sub organic EL device with a second light-emitting portion;
• a sealing unit with a conductive spacer in the sealing unit;
• and
• at least one flexible printed cable (FPC) coupled to the main or sub organic EL device;
• wherein the sealing unit hermetically seals the light-emitting portions facing each other, with the conductive spacer providing an electrical connection between the main and sub organic EL devices, and signals from the at least one FPC are provided directly to one of the devices, and through the conductive spacer to the remaining device.

A dual-type organic electroluminescence (EL) display comprising:

• a main organic EL device with a first light-emitting portion;
• a sub organic EL device with a second light-emitting portion;
• electrode lines formed on each of the EL devices;
• floating electrode lines formed on the main or sub EL device;
• a sealing unit;
• and
• at least one flexible printed cable (FPC) coupled to the main or sub organic EL device;
• wherein the floating electrode lines send signals received from the at least one FPC to a plurality of the electrode lines on the device not having the floating electrode lines.
