Abstract

In a method for manufacturing a flexible-type luminescent device, a flexible body is supplied from a flexible body supplying section to a luminescent material pattern forming section. Then, a luminescent material pattern is formed on the flexible body in the luminescent material pattern forming section. Finally, the flexible body is fed from the luminescent material pattern forming section to a flexible body receiving section.

Claims (36)

1. A method for manufacturing a flexible-type luminescent device, comprising the steps of:

supplying a flexible body from a flexible body supplying section to a luminescent material pattern forming section on a luminescent device-to-luminescent device basis;

forming a luminescent material pattern on said flexible body in said luminescent material pattern forming section; and

feeding said flexible body from said luminescent material pattern forming section to a flexible body receiving section on a luminescent device-to-luminescent device basis

wherein said flexible body is wound on a first roll in said flexible body supplying section and said flexible body receiving section comprises a second roll, and

wherein said flexible body supplying step comprises;

feeding said flexible body a distance corresponding to one said luminescent device by driving said first and second rolls at a first speed until a first position detecting mark is detected on said flexible body and driving said first and second rolls at a second speed smaller than said first speed after said first position detecting mark is detected and before a second position detecting mark is detected on said flexible body.

2. The method as set forth in claim 1 , wherein said luminescent material pattern forming step comprises the steps of;

aligning a luminescent material ejecting apparatus at one of specific positions;

operating said luminescent material ejecting apparatus after said luminescent material ejecting apparatus is aligned at the one of specific positions; and

repeating said luminescent material ejecting apparatus aligning step and said luminescent material ejecting apparatus operating step for all said specific positions.

3. The method as set forth in claim 2 , wherein said luminescent material ejecting apparatus comprises an ink jet type head having a nozzle for ejecting luminescent material.

4. The method as set forth in claim 1 , wherein said luminescent material pattern forming step comprises a step of vacuum-evaporating luminescent material and depositing said luminescent material through a shadow mask having holes onto said flexible body.

5. The method as set forth in claim 1 , wherein said luminescent material pattern forming step comprises a step of depositing luminescent material through a shadow mask having holes to said flexible body by a sputter process.

6. The method as set forth in claim 1 , wherein said luminescent device comprises a flexible-type organic electroluminescent device.

7. A method for manufacturing a flexible-type luminescent device, comprising the steps of:

supplying a flexible body from a flexible body supplying section to a luminescent material pattern forming section on a luminescent device-to-luminescent device basis;

forming a luminescent material pattern on said luminescent device of said flexible body by using an ink jet type head having nozzles for ejecting luminescent material in said luminescent material pattern forming section; and

feeding said flexible body from said luminescent material pattern forming section to a flexible body receiving section on a luminescent device to luminescent device basis,

wherein said flexible body is wound on a first roll in said flexible body supplying section and said flexible body receiving section comprises a second roll, and

wherein said flexible body supplying step comprises:

feeding said flexible body a distance corresponding to one said luminescent device by driving said first and second rolls at a first speed until a first position detecting mark is detected on said flexible body and driving said first and second rolls at a second speed smaller than said first speed after said first position detecting mark is detected and before a second position detecting mark is detected on said flexible body.

8. A method for manufacturing a flexible-type luminescent device, comprising the steps of:

supplying a flexible body from a flexible body supplying section to a luminescent material pattern forming section on a luminescent device-to-luminescent device basis;

forming a luminescent material pattern on said luminescent device of said flexible body by a vacuum evaporation process using a shadow mask having holes in said luminescent material pattern forming section; and

feeding said flexible body from said luminescent material pattern forming section to a flexible body receiving section on a luminescent device-to-luminescent device basis,

wherein said flexible body is wound on a first roll in said flexible body supplying section and said flexible body receiving section comprises a second roll, and

wherein said flexible body supplying step comprises

feeding said flexible body a distance corresponding to one said luminescent device by driving said first and second rolls at a first speed until a first position detecting mark is detected on said flexible body and driving said first and second rolls at a second speed smaller than said first speed after said first position detection mark is detected and before a second position detecting mark is detected on said flexible body.

9. A method for manufacturing a flexible-type luminescent device, comprising the steps of:

supplying a flexible body from a flexible body supplying section to a luminescent material pattern forming section on a luminescent device-to-luminescent device basis;

forming a luminescent material pattern on said luminescent device of said flexible body by a sputter process using a shadow mask having holes in said luminescent material pattern forming section; and

feeding said flexible body from said luminescent material pattern forming section to a flexible body receiving section on a luminescent device-to-luminescent device basis,

wherein said flexible body is wound on a first roll in said flexible body supplying section and said flexible body receiving section comprises a second roll, and

wherein said flexible body supplying step comprises:

feeding said flexible body a distance corresponding to one said luminescent device by driving said first and second rolls at a first speed until a first position detecting mark is detected on said flexible body and driving said first and second rolls at a second speed smaller than said first speed after said first position detecting mark is detected and before a second position detecting mark is detected on said flexible body.
