## Abstract

Systems and methods for fabricating an OLED are provided, which include dispensing a substrate material onto a substrate carrier, the substrate carrier being rotated by one or more drums, curing the substrate material to form a substrate, depositing at least one OLED onto the substrate, and separating the substrate from the substrate carrier.

## Claims

### Claim at position 1

1-34. (canceled)

### Claim 35

A system for fabricating an OLED, comprising:
a substrate carrier;
a dispensing device to dispense a substrate material onto the substrate carrier;
a curing device to cure the substrate material to form a substrate;
a depositing device to deposit an OLED onto the substrate; and
one or more rotatable drums in physical communication with the substrate carrier and configured to move the substrate carrier past each of the dispensing device, the curing device, and the depositing device.

### Claim 36 (depends on 35)

The system of claim 35, wherein the dispensing device continuously dispenses the substrate material onto the substrate carrier.

### Claim at position 4

37-38. (canceled)

### Claim 39 (depends on 35)

The system of claim 35, further comprising a lamination device to apply a cover film onto the OLED.

### Claim 40 (depends on 35)

The system of claim 35, further comprising a winding drum to wind the substrate with the deposited OLED from the substrate carrier.

### Claim 41 (depends on 35)

The system of claim 35, wherein the one or more rotatable drums consists of a single rotatable drum having a first surface to function as the substrate carrier.

### Claim 42 (depends on 41)

The system of claim 41, wherein the dispensing device, the curing device and the depositing device are arranged around the single rotatable drum.

### Claim at position 9

43-44. (canceled)

### Claim 45 (depends on 35)

The system of claim 35, wherein the substrate carrier includes surface features which molds a surface of the substrate to form surface features on the substrate.

### Claim 46

(canceled)

### Claim 47 (depends on 35)

The system of claim 35, further comprising a secondary dispensing device to, after the substrate is separated from the substrate carrier, deposit one or more material layers on a surface of the substrate opposite the surface upon which the OLED was deposited.

### Claim at position 13

48-52. (Canceled)
