The first supporting roller is configured to rotate based on a rotating central axis. The coating device has an opening. The opening of the coating device faces toward the first supporting roller. The coating device is configured to coat a flowable material toward the first supporting roller along a first direction through the opening. The drying device is located at a side of the rotating central axis adjacent to the coating device in the first direction and is configured to dry the flowable material. ## Claims ### Claim 1 A thin film coating system, comprising: at least one first supporting roller configured to rotate based on a rotating central axis; a coating device having an opening, the opening facing toward the first supporting roller, wherein the coating device is configured to coat a flowable material toward the first supporting roller along a first direction through the opening; and at least one drying device located at a side of the rotating central axis adjacent to the coating device in the first direction and configured to dry the flowable material. ### Claim 2 (depends on 1) The thin film coating system of claim 1, wherein the opening has a first width and the drying device has a second width in an extending direction of the rotating central axis, and the first width is greater than the second width. ### Claim 3 (depends on 1) The thin film coating system of claim 1, further comprising at least one second supporting roller located at a side of the rotating central axis away from the drying device in the first direction and configured to support a flexible substrate where the flowable material is coated thereon. ### Claim 4 (depends on 1) The thin film coating system of claim 1, wherein the flowable material is metal oxide. ### Claim 5 (depends on 1) The thin film coating system of claim 1, wherein the drying device comprises an infrared drying device. ### Claim 6 (depends on 5) The thin film coating system of claim 5, wherein the opening of the coating device has a projection projected on the first supporting roller along the first direction, and the infrared drying device and the projection are spaced apart by a distance in a range from about 1 mm to about 100 mm. ### Claim 7 (depends on 1) The thin film coating system of claim 1, wherein the drying device comprises an exhaust device, the exhaust device has at least one inlet and at least one outlet, the opening of the coating device has a first projection projected on the first supporting roller along the first direction, the exhaust device faces toward the first supporting roller along a second direction and has a second projection projected on the first supporting roller along the second direction, the second projection covers the first projection, and the second direction intersects the first direction. ### Claim 8 (depends on 7) The thin film coating system of claim 7, wherein a number of the at least one outlet is plural, and the outlets are equidistantly arranged on the exhaust device along an extending direction of the rotating central axis. ### Claim 9 (depends on 7) The thin film coating system of claim 7, wherein the exhaust device and the first projection are spaced apart by a distance in a range from about 10 mm to about 50 mm. ### Claim 10 (depends on 7) The thin film coating system of claim 7, wherein the second direction is substantially perpendicular to the first direction.
