Encapsulating OLED devices with transparent cover

1. A method for encapsulating one or more OLED devices with an transparent encapsulation cover, comprising the steps of:

(a) placing an OLED device onto an alignment fixture;

(b) after the OLED device is aligned on the alignment fixture removing the aligned OLED device and placing the OLED device at an adhesive receiving position;

(c) using an adhesive dispenser to dispense adhesive at the adhesive receiving position at one or more predetermined locations on the OLED device;

(d) removing the adhesive containing OLED device from the adhesive dispenser and placing the adhesive containing OLED device in an encapsulation device;

(e) removing an transparent encapsulation cover from a storage cassette and positioning the transparent encapsulation cover in the alignment fixture; and

(f) moving the transparent encapsulation cover into an engaging relationship with the adhesive on the OLED device to secure the transparent encapsulation cover onto the OLED device.

2. The method of claim 1 wherein step (e) includes causing a hold down vacuum to position the transparent encapsulation cover relative to the OLED device.

3. The method of claim 1 further including providing a robotic arm with a pick-up tool for performing step (a) and using the pick-up tool of the robotic arm to remove the transparent encapsulation cover from a storage cassette and position such removed transparent encapsulation cover in the encapsulation device.

4. The method of claim 3 further including using the pick-up tool to place the transparent encapsulation cover in the alignment fixture prior to moving the transparent encapsulation cover to the encapsulation device.

5. The method of claim 1 further including providing an inert atmosphere in the encapsulation device so that the inert atmosphere is captured between the transparent encapsulation cover and the OLED) device.

6. The method of claim 5 wherein the inert atmosphere is nitrogen.
