Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims priority to and benefits of Korean Patent Application No. 10-2022-0096799 under 35 U.S.C. § 119, filed in the Korean Intellectual Property Office (KIPO) on Aug. 3, 2022, the entire contents of which are incorporated herein by reference. BACKGROUND 1. Technical Field The disclosure relates to a film peeling apparatus and a method of peeling a film, which is capable of improving peeling efficiency. 2. Description of the Related Art A display device, which is a device that displays an image, includes a liquid crystal display (LCD), a plasma display panel (PDP), an organic light emitting diode device (OLED device), a field emission display (FED), an electrophoretic display device, and the like. Various types of panels or optical films are used in a field of manufacturing such a display device. Such panels or optical films are processed while moving in various process spaces during a process, and in this case, they are often handled in a state where a protective film is attached thereon to prevent contamination or damage to surfaces of the panels or optical films during process space movement. This protective film may be removed prior to performing a bonding or assembly process on the panels. It is to be understood that this background of the technology section is, in part, intended to provide useful background for understanding the technology. However, this background of the technology section may also include ideas, concepts, or recognitions that were not part of what was appreciated by those skilled in the pertinent art prior to a corresponding effective filing date of the subject matter disclosed herein. SUMMARY Embodiments provide a film peeling apparatus capable of improving peeling efficiency. Embodiments also provide a method of peeling a film, which is capable of improving peeling efficiency. However, embodiments of the disclosure are not limited to those set forth herein. The above and other embodiments will become more apparent to one of ordinary skill in the art to which the disclosure pertains by referencing the detailed description of the disclosure given below. An embodiment provides a film peeling apparatus including a frame; a first driver and a second driver connected to the frame; a first gripper connected to the first driver; a second gripper connected to the second driver; and a grip support spaced apart from the first gripper and the second gripper. The grip support and the first gripper may grip a release tape attached to an end of a protective film attached to a panel and extending to an outside of the panel. The grip support and the second gripper may grip the end of the protective film to which the release tape is attached. The grip support may include a first surface and a second surface facing the first surface. The first surface may be in contact with the first gripper and the second surface may be in contact with the second gripper. The grip support may include an anti-slip portion, and the anti-slip portion may form a second surface of the grip support. The first gripper may bring the release tape into contact with the first surface of the grip support and grip the release tape depending on a control of the first driver. The first gripper may further include a film detection sensor that detects whether the release tape is gripped. The second gripper may include a plurality of links that rotate depending on a control of the second driver. The second gripper may include a grip bar connected to the links and including a bent portion at an end of the grip bar. The bent portion of the second gripper may bring the protective film into contact with the second surface of the grip support and grip the protective film depending on a control of the second driver. The second gripper may include a bent portion bent at an end of the second gripper, and the second driver may horizontally move the second gripper so that the bent portion of the second gripper is in contact with the second surface of the grip support. The first gripper may grip the release tape and moves to peel a portion of the protective film. The second gripper may grip the portion of the protective film peeled off by the first gripper. The first gripper and the second gripper may simultaneously peel the portion of the protective film. An embodiment provides a method of peeling a film using a film peeling apparatus including a first gripper and a second gripper. The method includes positioning a panel to which a protective film is attached on a stage; gripping a release tape attached to a first end of the protective film by the first gripper; gripping the first end of the protective film to which the release tape is attached by the second gripper; and peeling the protective film by the film peeling apparatus moving from a first end of the panel to a second end of the panel. The second gripper may include a plurality of links. The second gripper may include a grip bar
