Abstract

The present disclosure provides a method and apparatus for forming a film, capable of for forming a film on an image in which a plurality of shapes overlap, wherein the method for forming a film includes setting a first shape within a target region; setting a second shape, at least partially overlapping the first shape; setting an edge processing profile applied to an edge portion of the first shape and an edge portion of the second shape; and forming a film on the edge portion of the first shape and the edge portion of the second shape, based on the edge processing profile.

First claim

What is claimed is:

1 . A method for forming a film, comprising:
setting a first shape within a target region; setting a second shape, at least partially overlapping the first shape; setting an edge processing profile applied to an edge portion of the first shape and an edge portion of the second shape; and forming a film on the edge portion of the first shape and the edge portion of the second shape, based on the edge processing profile.

2 . The method for forming a film of claim 1 , wherein the operation of forming a film is performed on the edge portion of the first shape and the edge portion of the second shape in one of a shape expansion direction or a shape reduction direction.

3 . The method for forming a film of claim 1 , wherein the operation of setting the edge processing profile comprises
setting a first edge processing profile including target film thickness information and direction information for forming a film according to a distance from the edge portion of the first shape; and setting a second edge processing profile including target film thickness information and direction information for forming a film according to a distance from the edge portion of the second shape, and applied independently of the first edge processing profile.

4 . The method for forming a film of claim 3 , wherein the second shape is a hole shape disposed inside the first shape, and
the second edge processing profile forms a film on the edge portion of the second shape in a second shape expansion direction from an edge line of the second shape outwardly of the second shape.

5 . The method for forming a film of claim 3 , wherein the second shape is a hole shape disposed inside the first shape, and
the second edge processing profile forms a film on the edge portion of the second shape in a second shape reduction direction from the edge line of the second shape inwardly of the second shape.

6 . The method for forming a film of claim 3 , wherein the second shape is a hole shape disposed inside the first shape,
wherein the method for forming a film further comprises, setting a third shape, which is a hole shape disposed inside the second shape; and setting a third edge processing profile including target film thickness information and direction information for forming a film according to a distance from an edge portion of the third shape, and applied independently of the first edge processing profile and the second edge processing profile.

7 . The method for forming a film of claim 6 , wherein the second edge processing profile forms a film on the edge portion of the second shape in a second shape expansion direction from an edge line of the second shape outwardly of the second shape, and
the third edge processing profile forms a film on the edge portion of the third shape in a third shape reduction direction from an edge line of the third shape inwardly of the third shape.

8 . The method for forming a film of claim 1 , wherein the edge processing profile comprises position information of a region in which a film is not formed among the target regions.

9 . The method for forming a film of claim 1 , wherein the edge processing profile comprises a plurality of layers with different target film thicknesses, and
the plurality of layers are sequentially applied to regions with the same target film thickness among the target regions.

10 . An apparatus for forming a film, comprising:
a substrate disposition unit on which a substrate including a target region is disposed; a film forming unit for forming a film on a preset image on the substrate; and a control unit controlling the film forming unit, wherein the control unit sets a first shape within the target region, sets a second shape, at least partially overlapping the first shape, sets an edge processing profile applied to an edge portion of the first shape and an edge portion of the second shape, and controls the film forming unit to form a film on the edge portion of the first shape and the edge portion of the second shape, based on the edge processing profile.

11 . The apparatus for forming a film of claim 10 , wherein the control unit controls the film forming unit to form a film on the edge portion of the first shape and the edge portion of the second shape in one of a shape expansion direction or a shape reduction direction.

12 . The apparatus for forming a film of claim 10 , wherein the control unit sets a first edge processing profile including target film thickness information and direction information for forming a film according to a distance from the edge portion of the first shape, and
sets a second edge processing profile including target film thickness information and direction information for forming a film according to a distance from the edge portion of the second shape, and applied independently of the first edge processing profile.

13 . The apparatus for forming a film of claim 12 , wherein the film forming unit comprises a nozzle discharging ink onto the substrate,
wherein the control unit controls a discharge amount of the nozzle to form a film on the edge portion of the second shape in a second shape expansion direction from an edge line of the second shape outwardly of the second shape, based on the second edge processing profile.

14 . The apparatus for forming a film of claim 12 , wherein the film forming unit comprises a nozzle discharging ink onto the substrate,
wherein the control unit controls a discharge amount of the nozzle to form a film on the edge portion of the second shape in a second shape reduction direction from an edge line of the second shape inwardly of the second shape, based on the second edge processing profile.

15 . The apparatus for forming a film of claim 12 , wherein the second shape is a hole shape disposed inside the first shape,
wherein the control unit sets a third shape, which is a hole shape disposed inside the second shape, and sets a third edge processing profile including target film thickness information and direction information for forming a film according to a distance from an edge portion of the third shape, and applied independently of the first edge processing profile and the second edge processing profile.

16 . The apparatus for forming a film of claim 15 , wherein the film forming unit comprises a nozzle discharging ink onto the substrate,
wherein the control unit controls a discharge amount of the nozzle to form a film on the edge portion of the second shape in a second shape expansion direction from an edge line of the second shape outwardly of the second shape, based on the second edge processing profile, and controls the discharge amount of the nozzle to form a film on the edge portion of the third shape in a third shape reduction direction from an edge line of the third shape inwardly of the third shape, based on the third edge processing profile.

17 . The apparatus for forming a film of claim 10 , wherein the edge processing profile comprises position information of a region in which a film is not formed among the target regions.

18 . The apparatus for forming a film of claim 10 , wherein the edge processing profile comprises a plurality of layers with different target film thicknesses, and
the control unit controls the film forming unit to sequentially apply the plurality of layers to regions with the same target film thickness among the target regions.

19 . An apparatus for forming a film, comprising:
a substrate disposition unit on which a substrate inc
