Abstract

A film peeling apparatus including a peeling unit, a peeling unit position adjusted, and a clamp. The peeling unit has uneven portions at an end portion thereof. The peeling unit is configured to peel off a protection film attached on a display panel. The peeling unit position adjuster is connected to the peeling unit. The peeling unit position adjuster is configured to adjust a position of the peeling unit. The clamp is disposed separately from the peeling unit. The clamp is configured to clamp the peeling unit.

First claim

What is claimed is:

1. A film peeling apparatus, comprising:
a peeling unit configured to peel off a protective film attached on a display panel;
a peeling unit position adjuster connected to the peeling unit and configured to adjust a position of the peeling unit; and a
clamp disposed separately from the peeling unit and configured to clamp a peeled-off portion of the protective film,
wherein the peeling unit includes a peeling pin configured to contact the protective film, and a peeling rod extending from the peeling pin and connected to the peeling unit position adjuster, wherein an end portion of the peeling pin had uneven portions.

2. The apparatus of claim 1 , wherein the peeling pin includes:
a first surface having a first width extending in a first direction; and
a second surface having a second width extending in a second direction,
wherein the second direction crosses the first direction, and
wherein the first width is greater than the second width.

3. The apparatus of claim 2 , wherein a longitudinal direction of the uneven portions is substantially parallel to the first direction.

4. The apparatus of claim 1 , further comprising
a stage configured to mount the display panel therein.

5. The apparatus of claim 1 , wherein adjacent uneven portions of the peeling unit are separated from each other by about 50 nm to about 400 nm.

6. The apparatus of claim 1 , further comprising
a turn-on test pad disposed in a peripheral portion of the display panel and is configured to be accessed for performing a turn-on test of the display panel.

7. A film peeling method, comprising:
providing a peeling unit having uneven portions at an end portion thereof;
contracting the peeling unit to a peripheral protective film attached to a peripheral portion of a display panel;
cutting the protective film disposed on the display panel using a laser;
separating the peripheral protective film from a display protective film of a display unit of the display panel along a cutting line by moving the peeling unit;
forming a curved portion in the peripheral protective film by moving the peeling unit; and
removing the peripheral protective film from the display panel.

8. The method of claim 7 , wherein a position of the peeling unit is adjusted by using a peeling unit position adjuster connected to the peeling unit.

9. The method of claim 7 , wherein the peeling unit includes a peeling pin configured to contact the protective film, and an end portion of the peeling pin may have the uneven portions extending in a first direction.

10. The method of claim 9 , wherein the peeling pin is disposed such that a longitudinal direction of the uneven portions is substantially parallel to the cutting line to allow the peeling pin to contact the peripheral protective film.

11. The method of claim 10 , wherein the peeling pin is moved in a second direction crossing the cutting line to separate the peripheral protective film from the display protective film.

12. The method of claim 10 , wherein the peeling pin is moved in the first direction to form a curved portion in the peripheral protective film.

13. The method of claim 12 , wherein the peripheral protective film is removed from the display panel by clamping the curved portion of the peripheral protective film with a clamp.

14. A film peeling apparatus, comprising:
a peeling unit having a plurality of uneven portions at an end portion thereof;
a peeling unit position adjuster connected to the peeling unit; and
a clamp disposed separately from the peeling unit to clamp a peeled-off portion of a protective film,
wherein adjacent uneven portions of the peeling unit are separated from each other by about 50 nm to about 400 nm.

15. The apparatus of claim 14 , further comprising
a stage configured to mount the display panel therein.

16. The apparatus of claim 14 , wherein the peeling unit includes:
a peeling pin configured to contact a protective film attached on a display panel; and
a peeling rod extending from the peeling pin to and connected to the peeling unit position adjuster.

17. The apparatus of claim 16 , wherein an end portion of the peeling pin has a plurality of uneven portions.

18. The apparatus of claim 16 , wherein the peeling pin includes steel (SUS), aluminum (Al), or polyether ether ketone (PEEK).

19. The apparatus of claim 16 , wherein the peeling pin in configured to exert a frictional force that is larger than an adhesive force of the protective film.

20. The apparatus of claim 16 , wherein
the peeling unit disposed above each of the protective film and the clamp, and
the clamp is disposed at a side of the protective film.
