Tiled display
A tiled display includes: first and second display devices disposed adjacent to each other, the first and second display devices including display areas each having light-emitting areas, and a seam between adjacent ones of the display areas. Each of the first and second display devices includes: a first base part in the display areas, a first support layer on the first base part in the display areas and the seam, a display layer on the first support layer in the display areas and the seam, a second support layer on the display layer in the display areas and the seam, and a second base part on the second support layer in the display areas. The first support layer of the second display device is disposed on the second support layer of the first display device in the seam.
1. A tiled display comprising:
first and second display devices disposed adjacent to each other, the first and second display devices each comprising a display area having light-emitting areas, and a seam between adjacent ones of the display areas,
wherein each of the first and second display devices comprises:
a first base part in the display area;
a first support layer on the first base part in the display area and the seam;
a display layer on the first support layer in the display area and the seam;
a second support layer on the display layer in the display area and the seam; and
a second base part on the second support layer in the display area,
a filler layer between a light emitting element layer and a wavelength conversion layer; and
a first sealing member in the seam and surrounding the filler layer on a planar surface;
a first gate driver in the seam;
a second sealing member in the seam; and
a second gate driver in the seam; and
wherein the first support layer of the second display device is disposed on the second support layer of the first display device in the seam.
2. The tiled display of claim 1 , further comprising:
an adhesive film attaching a lower surface of the first support layer of the second display device to an upper surface of the second support layer of the first display device in the seam.
3. The tiled display of claim 1 , wherein a side surface of the first support layer or a side surface of the second support layer of the first display device is in contact with a side surface of the first base part of the second display device.
4. The tiled display of claim 1 , wherein a side surface of the first support layer or a side surface of the second support layer of the second display device is in contact with a side surface of the second base part of the first display device.
5. The tiled display of claim 1 , wherein the display layer comprises:
a thin-film transistor layer on the first support layer and comprising a plurality of thin-film transistors;
a light emitting element layer on the thin-film transistor layer and comprising a plurality of light-emitting elements;
a wavelength conversion layer on the light emitting element layer and comprising wavelength-converting units corresponding to the light-emitting areas, respectively; and
a color filter layer on the wavelength conversion layer and comprising color filters corresponding to the light-emitting areas, respectively.
6. The tiled display of claim 5 , wherein the first sealing member of the first display device faces a side surface of the first base part of the second display device, and wherein the first sealing member of the second display device faces a side surface of the second base part of the first display device.
7. The tiled display of claim 5 , wherein the display layer is disposed on the thin-film transistor layer in the seam, and wherein the tiled display further comprises a gate driver electrically connected to the plurality of thin-film transistors in the display areas.
8. The tiled display of claim 1 , wherein each of the first and second base parts comprises a glass material, and wherein each of the first and second support layers comprise polyimide (PI).
9. The tiled display of claim 1 , wherein a thickness of the first base part or the second base part is greater than a thickness of the display layer.
