Abstract

A method for manufacturing a display apparatus including a plurality of modular includes arranging the plurality of modular displays on a chassis, each modular display from among the plurality of modular displays comprising a respective plurality of pixels including a red inorganic light emitting element, a green inorganic light emitting element, and a blue inorganic light emitting element, forming a film on the plurality of modular displays, and forming a cover between light emitting elements of the plurality of modular displays by removing a region of the film corresponding to the light emitting elements of the plurality of modular displays.

First claim

1 . A method for manufacturing a display apparatus comprising a plurality of modular displays, the method comprising:
arranging the plurality of modular displays on a chassis, each modular display from among the plurality of modular displays comprising a respective plurality of pixels including a red inorganic light emitting element, a green inorganic light emitting element, and a blue inorganic light emitting element; forming a film on the plurality of modular displays; and forming a cover between light emitting elements of the plurality of modular displays by removing a region of the film corresponding to the light emitting elements of the plurality of modular displays.

2 . The method of claim 1 , wherein the forming the cover comprises forming the cover on edges of adjacent modular displays from among the plurality of modular displays.

3 . The method of claim 2 , wherein the forming the cover comprises:
irradiating a portion of the film corresponding to the edges of the adjacent modular displays with a laser; and removing the region of the film except for the irradiated portion of the film.

4 . The method of claim 3 , the method further comprising:
detecting, through an optical inspection, the portion of the film corresponding to a seam region formed between the adjacent modular displays.

5 . The method of claim 3 , wherein the cover covers a seam region formed between the adjacent modular displays, and fills at least a part of the seam region.

6 . The method of claim 3 , wherein the film comprises a base film and a transfer film attached to the base film, and
wherein the forming the film comprises laminating the film on the plurality of modular displays so that the transfer film is disposed to face the plurality of modular displays.

7 . The method of claim 6 , wherein the forming the cover comprises forming the cover by removing the base film and a region of the transfer film which has not been irradiated by the laser.

8 . The method of claim 6 , wherein the transfer film has a thickness based on to a height of the red inorganic light emitting element, the green inorganic light emitting element, and the blue inorganic light emitting element.

9 . The method of claim 1 , wherein the forming the cover comprises forming the cover between the light emitting elements of each modular display of the plurality of modular displays.

10 . A display apparatus comprising:
a chassis; a plurality of modular displays arranged on the chassis such that a seam region is formed between adjacent modular displays from among the plurality of modular displays; a processor configured to control the plurality of modular displays to display an image, each modular display from among the plurality of modular displays comprising:
a substrate; and
a plurality of pixels comprising a red inorganic light emitting element, a green inorganic light emitting element, and a blue inorganic light emitting element, respectively, on the substrate; and
a cover that covers the seam region and is attached to respective edges of the adjacent modular displays that define the seam region.

11 . The display apparatus of claim 10 , wherein the cover fills at least a part of the seam region between the respective edges of the adjacent modular displays.

12 . The display apparatus of claim 10 , wherein the cover comprises a transfer film that has been irradiated with a laser to attach the transfer film to the respective edges of the adjacent modular displays that define the seam region, and
wherein the transfer film has a thickness based on a height of the red inorganic light emitting element, the green inorganic light emitting element, and the blue inorganic light emitting element.

13 . The display apparatus of claim 10 , wherein a width of the cover is less than a distance between adjacent pixels from among the plurality of pixels, and is greater than a distance between the respective edges of the adjacent modular displays from among the plurality of modular displays.
