Abstract
An apparatus for manufacturing a display device includes a first roller from which a film member is unwound, a second roller around which the film member is wound, a flatness maintainer that is arranged between the first roller and the second roller and keeps at least one of an upper surface and a lower surface of the film member, flat, and a sensing unit arranged on at least one of the upper surface of the film member and the lower surface of the film member and detecting droplets dropped from a head unit onto the film member.
Claims25
A method of manufacturing a display device, the method comprising:
- moving a film member by rotating one of a first roller unwinding the film member and a second roller around which the film member is wound;
- stopping the film member by stopping at least one of the first roller and the second roller;
- tensioning the film member by clamping a side of the film member;
- discharging droplets onto the film member;
- detecting the droplets on the film member;
- and
- controlling droplets discharged from a head unit based on a result of the detecting the droplets.
