Display module manufacturing apparatus and display module manufacturing method

1. A display module manufacturing apparatus comprising:

a stage on which a display module is disposed;

a heater disposed on the stage, and configured to heat a first area of the display module to generate a first bump disposed on the display module, wherein the heater comprises a plurality of side surfaces and a contact surface; and

a first bump controller detachably coupled to one side surface among the plurality of side surfaces and comprising a first bottom surface facing an upper surface of the stage, wherein the contact surface is closer to the upper surface of the stage than the first bottom surface,

wherein the first bump controller is configured to receive a heat from the heater and apply the heat to reduce a thickness of the first bump,

wherein the contact surface protrudes from the first bottom surface in a third direction by a predetermined thickness, and

wherein the contact surface is excluded from overlapping with the first bottom surface.

2. The display module manufacturing apparatus of claim 1 , wherein the first bottom surface is flat.

3. The display module manufacturing apparatus of claim 1 , wherein the first bottom surface comprises a curved surface.

4. The display module manufacturing apparatus of claim 1 , wherein at least a portion of the first bump controller makes contact with the one side surface.

5. The display module manufacturing apparatus of claim 1 , wherein the heater and the first bump controller have different thermal conductivities from each other.

6. The display module manufacturing apparatus of claim 1 , wherein the heater extends in a first direction, the plurality of side surfaces comprise first side surfaces opposed to each other in the first direction and second side surfaces opposed to each other in a second direction crossing the first direction, and the one side surface coupled to the first bump controller is one second side surface of the second side surfaces.

7. The display module manufacturing apparatus of claim 6 , further comprising a second bump controller detachably coupled to another second side surface of the second side surfaces.

8. The display module manufacturing apparatus of claim 7 , wherein the second bump controller comprises a second bottom surface facing the stage, and a first distance between the upper surface of the stage and the first bottom surface is different from a second distance between the upper surface of the stage and the second bottom surface.

9. The display module manufacturing apparatus of claim 6 , further comprising a gas controller spaced apart from the upper surface of the stage in the third direction crossing the first direction and the second direction, wherein a distance between the upper surface of the stage and the contact surface of the heater is smaller than or equal to a distance between the upper surface of the stage and the gas controller.

10. The display module manufacturing apparatus of claim 9 , wherein the gas controller comprises a spray unit that forms an air curtain.

11. The display module manufacturing apparatus of claim 9 , wherein the gas controller comprises a suction unit.

12. The display module manufacturing apparatus of claim 9 , wherein the gas controller is spaced apart from the heater in the first direction.

13. The display module manufacturing apparatus of claim 9 , wherein the gas controller is provided with an opening passing therethrough, and the opening has a circular shape.

14. The display module manufacturing apparatus of claim 9 , wherein the gas controller is inclined with respect to one of the first side surfaces.

15. The display module manufacturing apparatus of claim 9 , wherein a first portion of the gas controller is disposed in the heater, and a second portion of the gas controller protrudes from the heater in the third direction.
