Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Furthermore, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the present application, are given by way of illustration and explanation only, and are not intended to limit the present application. In this application, where the context requires otherwise, the words "upper" and "lower" used in relation to the device in use or operation will generally refer to the upper and lower extremities of the device, particularly as oriented in the drawing figures; while "inner" and "outer" are with respect to the outline of the device.
Referring to fig. 1, a tiled display device according to an embodiment of the present application includes a first display module 1, a second display module 2, and a cover plate 3, where the first display module 1 is tiled with the second display module 2, and the cover plate 3 covers the first display module 1 and the second display module 2. The first display module 1 includes a first SCF (Super Clean Foam) component 11, a first support plate 12, a first display panel 13, a first optical film 14, and a first optical adhesive 15, which are sequentially stacked, the second display module 2 includes a second SCF component 21, a second support plate 22, a second display panel 23, a second optical film 24, and a second optical adhesive 25, which are sequentially stacked, and the cover plate 3 covers the first optical adhesive 15 and the second optical adhesive 25.
Specifically, in the tiled display device shown in fig. 1, the first display panel 13 and the second display panel 23 are each provided with a frame area. The first display panel 13 includes a first display area (not shown) and a first frame area a, the first frame area a includes a first gap area D and a first non-display area J, and the first gap area D is disposed between the first non-display area J and the first display area. The second display panel 23 includes a second display region (not shown) and a second frame region C, the second frame region C includes a second gap region E and a second non-display region K, and the second gap region E is disposed between the second non-display region K and the second display region. Due to process variations, the first display panel 13 and the second display panel 23 have a stitching gap B therebetween. Therefore, the width of the seam L1 of the tiled display device is equal to the sum of the width of the first frame area a, the width of the second frame area C, and the width of the tiled gap B. Therefore, the width of the seam L1 is larger than the sum of the width of the first frame area A and the width of the second frame area C, and the seam L1 is large, so that the visual experience of a user is influenced.
Specifically, in the tiled display device shown in fig. 1, in order to reduce the seam L1, the optical film needs to be retracted in consideration of the influence of the bonding accuracy in the actual manufacturing process. Specifically, the end of the first optical film 14 corresponding to the joint is shrunk inward by a distance F, so that the encapsulation layer of the end of the first display panel 13 corresponding to the joint is exposed, and the first display panel 13 is at risk of package failure; the end of the second optical film 24 corresponding to the splice contracts inward by a distance G, which results in the exposure of the encapsulation layer of the end of the second display panel 23 corresponding to the splice, and the risk of package failure of the second display panel 23 occurs. In addition, because the end of the first optical film 14 corresponding to the splice contracts inwards, the end of the second optical film 24 corresponding to the splice contracts inwards, the first optical glue 15 covers the first optical film 14, and the second optical glue 25 covers the second optical film 24, so there is air between the first optical glue 15 and the second optical glue 25, when the cover plate 3 is attached, air bubbles are easily generated at the position, which increases the attachment difficulty of the cover plate 3.
Specifically, in the tiled display device shown in fig. 1, because the first display module 1 and the second display module 2 are in a separated state, the position of the tiled display device corresponding to the edge joint L1 cannot be effectively supported, the module strength at the edge joint L1 is poor, and the flatness is poor.
In order to improve the problems of the tiled display device shown in fig. 1, embodiments of the present application provide a tiled display module 100, a method for manufacturing the tiled display module, and an electronic device.

When the first display panel 111 and the second display panel 112 are arranged in the column direction, the first display panel 111 and the second display panel 112 are staggered in the column direction. When the first display panel 111 and the second display panel 112 are disposed in a plurality of rows and columns, the first display panel 111 and the second display panel 112 are alternately disposed in a row direction, and the first display panel 111 and the second display panel 112 are alternately disposed in a column direction.
Specifically, as shown in fig. 2, the first display panel 111 includes a first display area AA1 and a first frame area BA1, and the first frame area BA1 is located on at least one side of the first display area AA 1. The second display panel 112 is disposed on the light emitting side of the first display panel 111, and the light emitting side of the first display panel 111 is the same as the light emitting side of the second display panel 112. The second display panel 112 includes a second display area AA2 and a second frame area BA2, and the second frame area BA2 is at least located on one side of the second display area AA2 close to the first display panel 111.

Under the structure, the first spacing region D1 and the second spacing region D2 are buffer regions, which can prevent the second non-display region VA2 from overlapping with the first display region AA1 due to the process precision, thereby preventing the light emission of the first display region AA1 from being affected. In this embodiment, the width of the seam L2 is equal to the sum of the width of the first spacer D1, the width of the second spacer D2, and the width of the overlap area OLA, and the width of the seam L2 is smaller than the sum of the width of the first bezel area BA1 and the width of the second bezel area BA2, so that the seam L2 of the tiled display module 100 can be reduced, which is beneficial to improving the visual experience of the user.
