Referring to fig. 1 and fig. 2 in combination, fig. 1 is a schematic top view structure diagram of a tiled screen provided in an embodiment of the present application, and fig. 2 is a schematic cross-sectional structure diagram of the tiled screen in fig. 1. The tiled screen 1000 includes a motherboard 100 and a plurality of display modules (e.g., a first display module 201 and a second display module 202 shown in fig. 1 and 2) bound to the motherboard 100, and the plurality of display modules are tiled together to form a large-sized tiled screen 1000. Of course, the tiled display screen 1000 can further include a cover plate 300 located on a side of the plurality of display modules away from the motherboard 100, where the cover plate 300 is used to protect the plurality of display modules.
Optionally, the motherboard 100 includes a control layer 10 and a support member for supporting the control layer 10, where the support member includes a back plate 11 and a functional layer 12 located on a side of the back plate 11 away from the control layer 10. The back sheet 11 includes a polyethylene terephthalate (PET) substrate, and the like. The functional layer 12 includes a composite layer such as foam, copper foil, graphite, and the like, and is used for structural reinforcement of the back plate 11 and heat dissipation of the control layer 10.
The control layer 10 includes a binding terminal, a driving device, and a connection trace connecting the binding terminal and the driving device, where the driving device includes a driving IC and the like. The plurality of display modules are located on one side of the control layer 10 away from the backplane 11, and are bound to the binding terminals on the control layer 10, so as to electrically connect the display modules and the motherboard 100. Specifically, the driving signal on the driving device is transmitted to the corresponding display module through the connecting wire and the binding terminal in sequence, so that the corresponding display module can display the driving signal. Therefore, the driving device is arranged on the motherboard 100 and is electrically connected with the corresponding display module, so that the space for arranging the driving device on the display module can be saved, the frame of the display module is reduced, the frame area of the spliced part of the display module is reduced, and the splicing seam of the spliced part is reduced.
The following specifically describes how to electrically connect the display module and the motherboard 100 by taking two adjacent display modules spliced with each other as an example:
the two adjacent display modules are a first display module 201 and a second display module 202, each of the display modules includes a display area AA and a non-display area surrounding the display area AA, the non-display area includes a first frame area BD1 and a second frame area BD2 located at two opposite sides of the display area AA, and of course, the non-display area may further include a third frame area BD3 connected to the first frame area BD1 and the second frame area BD 2.
The first frame area BD1 of the first display module 201 and the first frame area BD1 of the second display module 202 are partially overlapped, that is, the orthographic projection of the first frame area BD1 of the first display module 201 on the motherboard 100 is overlapped with the orthographic projection of the first frame area BD1 of the second display module 202 on the motherboard 100, so that the frame area at the splicing position after the first display module 201 and the second display module 202 are spliced can be further reduced, and the splicing seam at the splicing position is reduced.
Specifically, each of the display modules includes a display panel attached to the motherboard 100 and electrically connected to the motherboard 100, for example, the first display module 201 includes a first display panel 21 attached to the motherboard 100 and electrically connected to the motherboard 100, and the second display module 202 includes a second display panel 22 attached to the motherboard 100 and electrically connected to the motherboard 100. Each display panel comprises a display area AA and an edge wiring area positioned on the periphery of the display area AA, and the display panel comprises a flexible OLED display panel and the like.
The display area AA of the display panel is a display area AA of the display module, and the edge routing area of the display panel is disposed corresponding to a non-display area of the display module, for example, the edge routing area of the display panel corresponds to the first frame area BD1 and the second frame area BD2 of the display module.
It can be understood that the edge routing area of the display panel is used for setting various binding wires, the binding wires are electrically connected to the control layer 10 on the motherboard 100 to electrically connect the edge routing area to the motherboard 100, and meanwhile, the binding wires are also electrically connected to a driving circuit in the display area AA of the display panel to electrically connect the display panel to the motherboard 100, so as to electrically connect the display module to the motherboard 100. It should be noted that, in the present application, the electrical connection between the edge routing area and the motherboard 100 refers to the electrical connection between the bonding trace in the edge routing area and the motherboard 100.
Furthermore, at the splicing position of two adjacent display modules, at least partial orthographic projections of the edge routing areas of the two adjacent display panels on the motherboard 100 are overlapped, so that partial frames of the splicing position of the two adjacent display modules are overlapped, and further the splicing seam of the splicing position is reduced.
Specifically, at the joint, the first display panel 21 includes a first edge routing area 211, the second display panel 22 includes a second edge routing area 221, and the first edge routing area 211 is located on a side of the second edge routing area 221 away from the motherboard 100, so that a height difference is formed between the first display panel 21 and the second display panel 22. Wherein the height difference means that a distance between the first display panel 21 and the motherboard 100 is different from a distance between the second display panel 22 and the motherboard 100 in a direction perpendicular to the motherboard 100.
The first edge routing area 211 corresponds to the first frame area BD1 of the first display module 201, and the second edge routing area 221 corresponds to the first frame area BD1 of the second display module 202. The orthographic projection of the first edge routing area 211 on the motherboard 100 is overlapped with the orthographic projection of the second edge routing area 221 on the motherboard 100, that is, the first edge routing area 211 and the second edge routing area 221 are partially overlapped in space, so that the orthographic projection of the first frame area BD1 of the first display module 201 on the motherboard 100 is overlapped with the orthographic projection of the first frame area BD1 of the second display module 202 on the motherboard 100, and further the frame area at the joint of the first display module 201 and the second display module 202 is reduced, so as to reduce the joint seam.
The first edge routing area 211 includes a first sub-area 2111 and a second sub-area 2112 located on a side of the first sub-area 2111 away from the display area AA of the first display panel 21, the second edge routing area 221 includes a third sub-area 2211 and a fourth sub-area 2212 located on a side of the third sub-area 2211 away from the display area AA of the second display panel 22, a forward projection of the second sub-area 2112 on the motherboard 100 coincides with a forward projection of the fourth sub-area 2212 on the motherboard 100, the first sub-area 2111 is electrically connected to the motherboard 100, and the third sub-area 2211 is electrically connected to the motherboard 100.
So that the first edge routing region 211 and the second edge routing region 221 partially coincide to reduce the splice seam; the non-overlapped portion of the first edge routing region 211 and the second edge routing region 221 is used for electrically connecting with the motherboard 100, so as to electrically connect the first display panel 21 and the second display panel 22 with the motherboard 100. For example, the first sub-region 2111 is electrically connected to the control layer 10 of the motherboard 100 through a first conductive layer 61, and the third sub-region 2211 is electrically connected to the control layer 10 of the motherboard 100 through a second conductive layer 62. Alternatively, the material of the first Conductive layer 61 and the second Conductive layer 62 may include at least one of a Conductive silver paste (ag paste), an Anisotropic Conductive Film (ACF), and the like.
Optionally, the first display panel 21 further includes a third edge routing area 212 disposed opposite to the first edge routing area 211, the third edge routing area 212 corresponds to the second frame area BD2 of the first display module 201, and the third edge routing area 212 is also electrically connected to the control layer 10 of the motherboard 100 through the first conductive layer 61. Correspondingly, the second display panel 22 further includes a fourth edge routing area 222 disposed opposite to the second edge routing area 221, the fourth edge routing area 222 corresponds to the second frame area BD2 of the second display module 202, and the fourth edge routing area 222 is also electrically connected to the control layer 10 of the motherboard 100 through the second conductive layer 62.
In order to achieve the partial overlapping of the first edge routing area 211 and the second edge routing area 221 in space, and further form a height difference between the first display panel 21 and the second display panel 22, the first display module 201 further includes a heightening layer 71 located on one side of the first display panel 21 close to the motherboard 100, and the heightening layer 71 is connected to the first display panel 21 and the motherboard 100. Specifically, the boosting layer 71 is connected to the first display panel 21 and the control layer 10 of the motherboard 100. Optionally, the material of the enhancing layer 71 includes an OCA, an OCR, or other adhesive material to bond the first display panel 21 and the control layer 10, so as to enhance the stability of the bonding between the first display panel 21 and the motherboard 100.
Further, the first space-avoiding area 711 is disposed on a side of the enhancement layer 71 corresponding to the first edge routing area 211, and the second edge routing area 221 is located in the first space-avoiding area 711, so that the first edge routing area 211 and the second edge routing area 221 are partially overlapped in a spatial direction perpendicular to the motherboard 100, so as to reduce a frame area at a joint of the first display module 201 and the second display module 202.
It can be understood that, due to the partial overlapping of the first edge routing area 211 and the second edge routing area 221 in space, a height difference is formed between the first display panel 21 and the second display panel 22, so that although a splicing seam at the splicing position of the first display module 201 and the second display module 202 is reduced, the height difference also makes the first display panel 21 and the second display panel 22 not in the same horizontal plane, which is easy to cause unevenness of the surface of the whole tiled screen 1000. This height difference needs to be filled up for this purpose:
specifically, the first display module 201 is attached to the cover plate 300 through a first adhesive layer 51, the second display module 202 is attached to the cover plate 300 through a second adhesive layer 52, and the thickness of the second adhesive layer 52 is greater than that of the first adhesive layer 51. The height difference between the first display panel 21 and the second display panel 22 is filled by increasing the thickness of the second adhesive layer 52, so that the surface of the whole spliced screen 1000 is flat.
Specifically, the first display module 201 further includes a first polarizer 31 and a first touch layer 41 located on one side of the first display panel 21 away from the motherboard 100, the second display module 202 further includes a second polarizer 32 and a second touch layer 42 located on one side of the second display panel 22 away from the motherboard 100, the first touch layer 41 is attached to the cover plate 300 through the first bonding layer 51, and the second touch layer 42 is attached to the cover plate 300 through the second bonding layer 52. Optionally, the material of the first adhesive layer 51 and the second adhesive layer 52 includes transparent optical glue or the like, such as OCA, OCR or the like.
Further, the first polarizer 31 is flush with the outer boundary of the first edge routing region 211 at the side close to the second polarizer 32; one side of the second polarizer 32 close to the first polarizer 31 is in contact with the first polarizer 31 to avoid a gap or interference between the first polarizer 31 and the second polarizer 32 due to the partial overlapping of the first display panel 21 and the second display panel 22 in space.
Correspondingly, the first touch layer 41 is flush with the outer boundary of the first edge routing area 211 at a side close to the second touch layer 42; a side of the second touch layer 42 close to the first touch layer 41 is in contact with the first touch layer 41 to avoid a gap or interference between the first touch layer 41 and the second touch layer 42 due to the spatial overlapping of the first display panel 21 and the second display panel 22.
It should be noted that, in the present application, the outer boundary of the edge routing area refers to a side of the edge routing area away from the display area, for example, the outer boundary of the first edge routing area 211 refers to a boundary of the first edge routing area 211 away from the display area AA of the first display panel 21.
In an embodiment, please refer to fig. 1 to 5, fig. 3 is another schematic top view structure diagram of a tiled screen provided in an embodiment of the present application, fig. 4 is a schematic cross-sectional structure diagram of the tiled screen in fig. 3, and fig. 5 is a schematic detail structure diagram of a second edge routing area in fig. 4. Unlike the above embodiments, in the tiled display 1001 of this embodiment, an orthogonal projection of the first edge routing area 211 on the motherboard 100 coincides with an orthogonal projection of the second edge routing area 221 on the motherboard 100, and the first edge routing area 211 is electrically connected to the motherboard 100 through the second edge routing area 221.
Specifically, an orthographic projection of the first edge routing area 211 on the motherboard 100 coincides with an orthographic projection of the second edge routing area 221 on the motherboard 100, so that the first frame area BD1 of the first display module 201 coincides with the first frame area BD1 of the second display module 202, so as to further reduce a frame area at a spliced position after splicing the first display module 201 and the second display module 202, and thus reduce a splicing seam at the spliced position.
Since the first edge routing region 211 completely overlaps the second edge routing region 221, the first edge routing region 211 has no extra space for electrical connection with the motherboard 100, and thus the first edge routing region 211 is electrically connected with the motherboard 100 through the second edge routing region 221. Specifically, the first edge routing region 211 is electrically connected to the second edge routing region 221 through a third conductive layer 63, and the second edge routing region 221 is electrically connected to the control layer 10 of the motherboard 100 through a fourth conductive layer 64. The material of each of the third conductive layer 63 and the fourth conductive layer 64 may be the same as that of the first conductive layer 61.

The second trace 224 is electrically connected to the control layer 10 of the motherboard 100 through the fourth conductive layer 64, so as to electrically connect the second edge trace area 221 to the motherboard 100, and further electrically connect the second display panel 22 to the motherboard 100.
It should be noted that, although the first trace 223 and the second trace 224 are both electrically connected to the control layer 10 through the fourth conductive layer 64, there is no electrical connection relationship between the first trace 223 and the second trace 224. The fourth conductive layer 64 may include a plurality of conductive portions insulated from each other, and the first trace 223 and the second trace 224 are electrically connected to different conductive portions, respectively, or the fourth conductive layer 64 is made of an anisotropic conductive film and is only electrically connected in a direction perpendicular to the motherboard 100.
