Display module manufacturing apparatus and display module manufacturing
A display module manufacturing apparatus includes 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, and wherein the heater includes 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 including a first bottom surface facing an upper surface of the stage. The contact surface is closer to the upper surface of the stage than the first bottom surface.
1. A display module manufacturing method, comprising:
providing a display module comprising a display panel and a protective film attached to the display panel on a stage;
coupling a bump controller to a side surface of a heater;
heating a first area of the protective film overlapping a contact surface of the heater using the heater to modify at least a part of the first area of the protective film; and
heating a second area of the protective film overlapping a bottom surface of the bump controller using the bump controller to modify at least a part of the second area of the protective film, wherein the bottom surface of the bump controller is positioned higher than the contact surface of the heater.
2. The method of claim 1 , wherein the first area is adjacent to the second area, and when heating the first area and the second area of the protective film, the heater contacts and presses the first area.
3. The method of claim 1 , wherein the bump controller faces the second area and the heater faces the first area.
4. The method of claim 1 , further comprising sucking a portion of the protective film using a gas controller disposed on the stage.
5. The method of claim 4 , wherein the gas controller comprises a suction unit.
6. The method of claim 1 , further comprising forming an air curtain using a gas controller disposed on the stage.
7. The method of claim 6 , wherein the gas controller comprises a spray unit that forms the air curtain.
8. The method of claim 4 , wherein the gas controller is spaced apart from the heater in a first direction.
9. The method of claim 4 , wherein the gas controller is provided with an opening passing therethrough, and the opening has a circular shape.
10. The method of claim 4 , 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 a third direction.
11. The method of claim 1 , wherein the bump controller comprises the bottom surface, and
wherein the bottom surface is flat.
12. The method of claim 1 , wherein the bump controller comprises the bottom surface, and
wherein the bottom surface comprises a curved surface.
13. The method of claim 1 , wherein the heater and the bump controller have different thermal conductivities from each other.
14. The method of claim 1 , wherein the heater and the bump controller are detachably coupled.
15. The method of claim 1 , wherein the side surface comprises a first side surface and a second side surface facing the first side surface, and
wherein the bump controller comprises a first bump controller coupled to the first side surface and a second bump controller coupled to the second side surface.
16. The method of claim 15 , wherein the first bump controller comprises a first bottom surface,
wherein the second bump controller comprises a second bottom surface, and
wherein a first distance between an 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.
17. The method of claim 1 , wherein the display panel and the stage directly contact each other, and
wherein the protective film faces the heater.
18. The method of claim 1 , wherein the heater is configured to generate a first bump disposed on the display module,
wherein the 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 bump controller comprises the bottom surface, and
wherein the contact surface of the heater protrudes from the bottom surface in a third direction by a predetermined thickness.
19. The method of claim 1 , wherein the contact surface of the heater is excluded from overlapping the bump controller when viewed from a plane.
20. The method of claim 1 , wherein the protective film is modified such that a thickness in the first area, in a third direction, is smaller than a thickness in the second area.
