Abstract

A mask frame assembly and a method of manufacturing the same are disclosed. In one aspect, the mask frame assembly for an organic light-emitting diode display includes a frame including a supporting unit, wherein an opening is formed in the frame. The assembly also includes a unit mask including a deposition pattern portion, wherein the unit mask extends in a first direction, and is fixed to the supporting unit. The assembly further includes a first supporter configured to support the unit mask, wherein a magnet is placed on at least one portion of the first supporter.

First claim

What is claimed is:

1. A mask frame assembly for an organic light-emitting diode display, comprising:
a frame including a mask supporter, wherein an opening is formed in the frame;
a unit mask including a deposition pattern portion, wherein the unit mask extends in a first direction, and is fixed to the mask supporter; and
a first supporter configured to support the unit mask, wherein a magnet is placed on at least one portion of the first supporter,
wherein the unit mask includes edges found at opposing ends thereof, and wherein the first supporter contacts an edge of the unit mask,
wherein the magnet includes first and second portions, wherein the unit mask includes first and second unit masks adjacent to each other, and wherein the first and second portions of the magnet respectively contact the first and second unit masks.

2. The mask frame assembly of claim 1 , wherein the first supporter and the unit mask are formed substantially parallel with each other in the first direction.

3. The mask frame assembly of claim 2 , wherein the magnet is configured to pull the unit mask toward the first supporter in a second direction crossing the first direction.

4. The mask frame assembly of claim 1 , wherein the magnet is placed at a center of the first supporter in the first direction.

5. The mask frame assembly of claim 1 , wherein the magnet comprises a plurality of magnets placed in the direction of the length of the first supporter, and wherein the magnets are provided to be substantially symmetrical with regard to a center of the first supporter in the first direction.

6. The mask frame assembly of claim 5 , wherein the sizes of the magnets are reduced progressively when the magnets are farther from the center of the first supporter toward both ends thereof.

7. The mask frame assembly of claim 1 , wherein the first supporter has a groove corresponding to and accommodating the magnet.
