The organic light emitting display device is a self-luminous device that emits light by itself, and has advantages of fast response speed, luminous efficiency, luminance and viewing angle. In addition, since the device can be formed on a flexible substrate such as plastic, a flexible display device can be realized.

Recently, as a large-area, high-resolution organic light emitting display device is required, a plurality of sub-pixels are included in a single panel. In general, since a mask is used for patterning the red (R), green (G), and blue (B) sub-pixels, in order to implement a large-area display device, a corresponding large-area fine-pixel (FMM) is used. Metal Mask) is required.

As such, since the FMM is used for pixel patterning, it is preferred to form a fine pattern in the FMM. However, it is now recognized as a very difficult technique because FMM is difficult to deal with.

FMM, as the name suggests, has a very thin thickness. Therefore, it is not easy to fix the FMM, and various problems such as folding or damage even with a very small force are occurring. Therefore, the most important technology to form a pattern on the FMM is to stably fix the FMM and move the FMM as needed.

It is an exploded view of a part of the jig part.

The jig part 200 of the FMM (fine-metal mask) handling jig for pattern formation according to the present invention according to an embodiment includes a base part 210 and a fixing part 220 .

The base portion 210 is formed with a set length and includes a flat surface. A mask may be disposed on a flat surface of the base part 210 . Fixing parts 220 may be formed at both ends of the base part 210 . Here, the fixing part 220 may be formed on the other surface (the upper surface observed in FIG. 3 ) of both ends of the base part 210 .

A grip portion may be formed on the other surface of the base portion 210 . The grip portion is formed in the shape of a “U” and is spaced apart to be gripped.

The fixing part 220 may apply a magnetic force in one direction so that the mask is attached to the base part 210 . Here, since the mask is made of metal using FMM, an attractive force may be applied to the mask so that the mask is attached.

The fixing unit 220 may include a housing 221 , a magnetic control body 222 , and a magnetic bar 223 .

The housing 221 constitutes the exterior of the fixing part 220 and a space is formed therein. A magnetic control body 222 , a magnetic bar 223 , etc. may be disposed in a space inside the housing 221 . The housing 221 may have a moving groove formed on the other surface along the longitudinal direction. A moving unit 224, which will be described later, may be disposed in the moving groove.

The magnetic control body 222 is formed in a cylindrical shape. The magnetic control body 222 is rotatably formed in the housing 221 based on the axis. That is, the magnetic control body 222 has rotation shafts 222a disposed on both sides, and the rotation shaft 222a may be disposed between the first cylinder 231 and the second cylinder 232, which will be described in detail later. have. The magnetic control body 222 is formed so that the rotation shaft 222a is rotated between the first cylinder 231 and the second cylinder 232 and can be rotated.

Here, the magnetic control body 222 may be connected to the moving part 224 in the form of a bar having a set length. The moving part 224 passes through the moving groove of the housing 221 as shown in FIG. 5 and is disposed to be observable to the outside. Accordingly, the magnetic control body 222 may be rotated at an angle set by the force applied to the moving unit 224 .

The magnetic control body 222 is formed with an installation groove (222b). The installation groove 222b of the magnetic control body 222 may be formed in the form of a block. A magnetic bar 223 that forms a magnetic force may be disposed in the installation groove 222b. Accordingly, the magnetic force applied by the magnetic bar 223 according to the movement of the magnetic control body 222 may be directed toward one surface of the base portion 210 .

That is, when the moving part 224 is moved to the right with reference to FIG. 5 , the magnetic control body 222 is rotated clockwise according to the movement of the moving part 224 so that the magnetic bar 223 is moved to the base part 210 . ) may be disposed to face the center so that the magnetic force does not face one side of the base unit 210. Conversely, when the moving unit 224 is moved to the left, the magnetic control body 222 rotates counterclockwise. Moving, the magnetic bar 223 may be disposed toward one side. Therefore, both sides of the mask disposed on one side of the base unit 210 may be attached to one side of the base unit 210 by the fixing unit 220 .

Meanwhile, in order to guide the magnetic force, the magnetic control body 222 is preferably made of a material through which the magnetic force of the magnetic bar 223 does not pass (eg, a ferromagnetic material or a quasi-ferromagnetic material). Accordingly, the magnetic force in which the magnetic bar 223 is formed may be formed only in a direction in which the magnetic control body 222 and the magnetic bar 223 do not contact each other.

7 is a top view of a pusher part and a fixing part of a fine-metal mask (FMM) handling jig for pattern forming according to an embodiment of the present invention, and FIG. It is an enlarged view of the pusher part of the metal mask) handling jig.

The present invention according to an embodiment may include a pusher unit 230 . The pusher part 230 may move the fixing part 220 in an outward direction away from the center of the base part 210 or in an inward direction closer to the center of the base part 210 . More precisely, the pusher unit 230 may move the magnetic control body 222 . Accordingly, the position of the magnetic bar 223 may be changed. Therefore, the present invention can pull the mask taut by moving both ends of the mask. Or conversely, the present invention may loosen the mask.

Looking at the pusher unit 230 that enables such an operation, the pusher unit 230 may include a handle unit 231 , a connection unit 232 , and an operation unit 233 . The handle part 231 is disposed on the other surface of the base part 210 , and is formed in the shape of a bar to make the grip comfortable. The handle portion 231 may be moved up or down. The connection part 232 has one side connected to the handle part 231 and a hinge connection. Accordingly, the connection unit 232 may change the upper and lower movements of the handle unit 231 to left and right horizontal movements. One side of the operation unit 233 is hinge-connected to the other side of the connection unit 232 . As can be seen in FIG. 7 , the operation unit 233 penetrates through the housing 221 . Accordingly, the operation unit 233 may move in a linear direction according to the movement of the connection unit 232 . The operation unit 233 may have the other side in contact with the magnetic control body 222 . Therefore, the position of the magnetic control body 222 may be changed by being pushed by the operation unit 233 according to the movement of the operation unit 233 .

Here, a circular roller may be disposed at the end of the operation unit 233 for the stable and smooth movement of the magnetic control body 222 .

Meanwhile, as can be seen in FIG. 6 , the magnetic control body 222 may include an arrangement groove 222c and an auxiliary bar 225 to accurately move according to the movement of the operation unit 233 .

Here, the arrangement groove 222c may be arranged to be spaced apart from the installation groove 222b along the circumference of the magnetic control body 222 as much as the installation groove 222b is set. The arrangement groove 222c is formed in a hexahedral shape in the same form as the installation groove 222b. An auxiliary bar 225 having at least one surface flattened is disposed in the arrangement groove 222c.

Accordingly, the moving part 224 may be in contact with the auxiliary bar 225 in a flat form, not the magnetic control body 222 . Therefore, since the moving part 224 pushes the flat part in one direction, the magnetic control body 222 can be moved stably.

In addition, the magnetic control body 222 is a second cylinder 232 in which the first cylinder 231 and the elastic body 233 are wrapped so that the magnetic control body 222 can be stably moved according to the movement of the pusher unit 230 . ), the rotating shaft 222a may be disposed by an elastic connector composed of.

As can be seen in FIG. 7 , the rotation shaft 222a of the magnetic control body 222 is disposed between the first cylinder 231 and the elastic connector. The elastic connector may include a second cylinder 232 and an elastic body 233 surrounding the second cylinder 232 . The first cylinder 231 and the second cylinder 232 may be respectively positioned to be spaced apart from each other, and the rotation shaft 222a of the magnetic control body 222 may be disposed therebetween.

Accordingly, as the operation unit 233 pushes or pulls the magnetic control body 222 , the positions of the first cylinder 231 and the second cylinder 232 may be changed. In addition, the second cylinder 232 applies an elastic force to the second cylinder 232 by the elastic body 233 disposed to surround the second cylinder 232 and prevents the magnetic control body 222 from being moved abruptly by the elastic force. can do.

It shows the state in which the FMM (Fine-Metal Mask) is connected to the bracket part.

On the other hand, even if the magnetic force is applied by the magnetic bar 223, there is a problem that the magnetic force of the magnetic bar 223 is too strong or weak, so that the mask is not properly adsorbed (attraction due to magnetic force), or the direction of the magnetic force is different from the mask Since it is not in a vertical direction, a problem in which the mask is incorrectly fixed to the jig part 200 may occur.

Therefore, the present invention may include the bracket part 300 to solve this problem. The bracket part 300 is formed of metal, and a fixing hole 310 may be formed in the center along the longitudinal direction. In the bracket part 300, as shown in FIG. 10, the end of the mask passes through the fixing hole 310 from one side of the bracket part 300 toward the other side, and is bent at the other side to be fixed to the bracket part 300. can Therefore, the above-described fixing of the mask and the fixing unit 220 may actually be the fixing of the bracket unit 300 and the fixing unit 220 to which the mask is fixed.

As such, the present invention utilizes the bracket unit 300 so that the fixing unit 220 and the mask are more firmly attached and moved, so that the mask can be more firmly attached to the base unit 210 , and the pusher unit 230 . According to the movement by , the mask can move more precisely in response to a change in the position of the magnetic control body 222 .
