Method of manufacturing a flexible display
View Patent ↗A method of manufacturing a flexible display is provided, which includes: adhering a plastic substrate on a supporter using an adhesive; forming a thin film pattern on the plastic substrate; and separating the plastic substrate from the supporter using a solvent including THF (tetrahydrofuran). In this manner, the plastic substrate may be tidily separated from the supporter by using THF.
1. A method of manufacturing a flexible display, the method comprising:
adhering a first surface of a plastic substrate on a supporter using an adhesive, wherein an entire first surface of the plastic substrate receives the adhesive;
forming a thin film pattern on a second surface of the plastic substrate; and
separating the plastic substrate from the supporter using a solvent including THF (tetrahydrofuran).
2. The method of claim 1 , wherein the adhesive induces a silicon based adhesive.
3. The method of claim 1 , wherein the solvent includes an additive.
4. The method of claim 3 , wherein the additive includes an organic halogen.
5. The method of claim 4 , wherein the additive includes chloroform or dichloromethane.
6. The method of claim 5 , wherein the amount of the additive is in the range of from more than 0 percentage to about 30 percentage.
7. The method of claim 1 , wherein the adhesive comprises a tape having adhesion surfaces on both sides of the tape.
8. The method of claim 1 , wherein the plastic substrate is coated by a hard-coating layer.
9. The method of claim 8 , wherein the hard-coating layer includes acrylic resin.
10. The method of claim 1 , wherein the plastic substrate includes:
an organic layer;
an under-coating layer formed on the both surfaces of the organic layer;
a barrier layer formed on the under-coating layer; and
a hard-coating layer formed on the barrier layer.
11. The method of claim 10 , wherein the organic layer is made of one material selected from polyacrylate, polyethylene-terephthalate, polyethylene-naphthalate, polycarbonate, polyarylate, polyether-imide, polyehtersulfone, and polyimides.
12. The method of claim 10 , wherein the under-coating layer and the hard-coating layer include acrylic resin.
13. The method of claim 10 , wherein the barrier layer includes SiO2 or Al2O3.
14. The method of claim 10 , wherein the thin film pattern includes an inorganic layer.
15. The method of claim 1 , wherein the supporter includes a glass.
16. The method of claim 1 , wherein the display includes a liquid crystal display.
17. The method of claim 1 , wherein the display includes an organic light emitting diode display.
