Description

Technical Field

[0001] The present invention relates to display technology, and in particular to a panel assembly and a display device. Background Art

[0002] With the continuous development of display technology, the manufacturing technology of display screens has become increasingly mature, and large-size screens are widely used in various indoor and outdoor occasions. Large-size spliced ​​display screens have replaced large-size display screens due to their portability, low failure rate, long life, low power consumption and other advantages and are loved by more and more users.

[0003] A large-sized spliced ​​display screen is formed by splicing multiple small display panels. The frame size of each display panel will affect the display effect at the gap between the display panels, thereby affecting the display effect of the large-sized spliced ​​display screen. In the prior art, the circuits and chips in the non-display area of ​​the display panel are arranged on the back of the display panel, and the side wiring is used to go around to the back of the display panel and connect to the circuits and chips on the back of the display panel.

[0004] However, since the side wiring is a metal wire, winding the wire on the side will increase the risk of the metal wire breaking. Therefore, how to reduce the side wiring breakage problem while reducing the frame size of the display panel and improving the display effect has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The present invention provides a panel assembly and a display device, so as to improve the problem of side wiring breakage while ensuring that the panel assembly has a high screen-to-body ratio.

[0006] According to one aspect of the present invention, there is provided a panel assembly, comprising: at least one display substrate;

[0007] The display substrate comprises a substrate, and a plurality of display units and a plurality of signal lines arranged in an array on the substrate; the signal lines are electrically connected to the display units; the substrate comprises a front side and a back side opposite to each other, and a plurality of side sides connecting the front side and the back side; the display units and at least part of the signal lines are located on the front side;

[0008] The display substrate includes a first display substrate; the multiple side surfaces of the first display substrate include at least one first side surface; the first side surface includes an arc-shaped protrusion; at least one side routing is arranged on the first side surface; in the first display substrate, one end of the side routing is electrically connected to at least part of the signal line, and the other end of the side routing extends along the arc-shaped protrusion to the back surface.

[0009] According to another aspect of the present invention, a display device is provided, comprising: the above-mentioned panel assembly.

[0010] The technical solution of the embodiment of the present invention is to arrange a display unit and at least part of the signal lines on the front side of the substrate in the display substrate of the panel assembly, the side of the substrate includes a first side with an arc-shaped protrusion, and at least one side routing is arranged on the first side including the arc-shaped protrusion, so that one end of the side routing is electrically connected to at least part of the signal lines, and the other end of the side routing extends along the arc-shaped protrusion to the back side of the substrate. In this way, the side routing can be smoothly transitioned from the front side of the substrate to the side of the substrate, and from the side of the substrate to the back side of the substrate, thereby reducing the bending degree of the side routing at various positions on the side. Compared with the case where the side of the substrate is a straight surface, it can improve the side routing caused by the large bending degree of the side routing at the corner position where the substrate side is connected to the substrate front and the substrate back. The problem of breakage can be solved, thereby ensuring the integrity of the side routing, improving the accuracy of signal transmission by the side routing, and further improving the display effect of the display substrate. The side routing is not easy to break and can also increase the service life of the side routing, thereby increasing the service life of the display substrate; at the same time, when the other end of the side routing extends to the back side of the substrate along the arc-shaped protrusion, the side of the display substrate can be used to arrange the circuit, that is, the side of the display substrate can be used as the fan-out area of ​​the display substrate, thereby reducing the frame size of the display substrate and increasing the screen-to-body ratio of the display substrate; on this basis, the driving circuit, driving chip, etc. of the display substrate can also be arranged on the back side of the substrate, thereby further reducing the frame size of the display substrate, increasing the screen-to-body ratio of the spliced ​​panel assembly, and further improving the display effect of the spliced ​​panel assembly.

[0029] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] Figure 1 A schematic diagram of a cross-sectional structure of a panel assembly in the related art. The panel assembly 10 in the related art includes Figure 1 The display substrate shown in the figure can be spliced ​​to form a panel assembly with a larger area. The display substrate in the related art includes a substrate 01, and the substrate 01 includes an upper surface 011 and a lower surface 012. There are multiple display units 05 and multiple signal lines 02 on the upper surface 011. In order to reduce the border width of the display substrate, the current display substrate will use the side surface 013 between the upper surface 011 and the lower surface 012 for routing, and the side routing 021 is electrically connected to the signal line 02 to reduce the border width of the display substrate.

[0032] However, the side surface 013 of the existing substrate 01 is a flat surface, which makes the connection position of the upper surface 011 and the side surface 013 have a large angle. Even if a transition surface 03 is set here to connect the upper surface 011 and the side surface 013, there are corresponding angles between the transition surface 03 and the upper surface 011, and between the transition surface 03 and the side surface 013. This makes it very easy for the side trace 021 to break when it extends from the upper surface 011 to the side surface 013 because the angle position where the upper surface 011 and the side surface 013 are connected has a large bending degree. Correspondingly, there will be a large angle at the connection position between the side surface 013 and the back surface 012, which will easily lead to the risk of disconnection when the side wiring 021 extends from the side surface to the back surface 012; and, when multiple display substrates are spliced ​​and fitted, the side wiring 021 will be easily damaged and broken due to friction and collision between the display substrates, which increases the risk of poor signal contact and makes it impossible to guarantee the connection effect of the signal line, resulting in the inability of the spliced ​​display substrates to accurately display the corresponding images, and will also affect the display effect of the larger display component that is finally formed.

[0033] Based on the above technical problems, an embodiment of the present invention provides a panel assembly, including: at least one display substrate; the display substrate includes a substrate, and a plurality of display units and a plurality of signal lines arranged in an array on the substrate; the signal lines are electrically connected to the display units; the substrate includes a front side and a back side opposite to each other, and a plurality of side sides connecting the front side and the back side; the display units and at least part of the signal lines are located on the front side; the display substrate includes a first display substrate; the plurality of side sides of the first display substrate include at least one first side side; the first side side includes an arc-shaped protrusion; at least one side routing is arranged on the first side side; in the first display substrate, one end of the side routing is electrically connected to at least part of the signal lines, and the other end of the side routing extends along the arc-shaped protrusion to the back side.

[0034] By adopting the above technical solution, a display unit and at least part of the signal lines are arranged on the front side of the substrate in the display substrate of the panel assembly, the side surface of the substrate includes a first side surface provided with an arc-shaped protrusion, and at least one side routing is arranged on the first side surface including the arc-shaped protrusion, so that one end of the side routing is electrically connected to at least part of the signal lines, and the other end of the side routing extends along the arc-shaped protrusion to the back side of the substrate. In this way, the side routing can be smoothly transitioned from the front side of the substrate to the side surface of the substrate, and from the side surface of the substrate to the back side of the substrate, thereby reducing the bending degree of the side routing at various positions on the side surface. Compared with the case where the side surface of the substrate is a straight surface, the side routing caused by the large bending degree of the side routing at the corner position where the substrate side surface connects the substrate front surface and the substrate back surface can be improved. The problem of breakage can be solved, thereby ensuring the integrity of the side routing, improving the accuracy of signal transmission by the side routing, and further improving the display effect of the display substrate. The side routing is not easy to break and can also increase the service life of the side routing, thereby increasing the service life of the display substrate; at the same time, when the other end of the side routing extends along the arc-shaped protrusion to the back of the substrate, the side layout of the display substrate can be used, that is, the side of the display substrate can be used as the fan-out area of ​​the display substrate, thereby reducing the frame size of the display substrate and increasing the screen-to-body ratio of the display substrate; on this basis, the driving circuit, driving chip, etc. of the display substrate can also be arranged on the back of the substrate, thereby further reducing the frame size of the display substrate, increasing the screen-to-body ratio of the spliced ​​display panel, and improving the display effect of the spliced ​​panel assembly.

[0035] The above are the core invention points of the embodiments of the present invention. The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Figure 2 A schematic diagram of a cross-sectional structure of a panel assembly provided by an embodiment of the present invention is shown in FIG. Figure 2As shown, the panel assembly 20 includes at least one display substrate, the display substrate includes a substrate 110, and a plurality of display units 120 and a plurality of signal lines 130 arranged in an array on the substrate 110; the signal line 130 is electrically connected to the display unit 120; the substrate 10 includes a front side 101 and a back side 102 opposite to each other, and a plurality of side surfaces 103 connecting the front side 101 and the back side 102; the display unit 120 and at least part of the signal line 130 are located on the front side 101; the display substrate includes a first display substrate 100; the plurality of side surfaces 103 of the first display substrate 100 include at least one first side surface 1031; the first side surface 1031 includes an arc-shaped protrusion 111; at least one side edge wiring 133 is arranged on the first side surface 1031; in the first display substrate 100, one end of the side edge wiring 133 is electrically connected to at least part of the signal line 130, and the other end of the side edge wiring 133 extends along the arc-shaped protrusion 111 to the back side 102. The substrate 110 may include a flexible substrate or a rigid substrate, which is not specifically limited in the embodiment of the present invention.

[0037] Exemplarily, the side surface 103 of the substrate 110 is designed to include a first side surface 1031 with an arc-shaped protrusion 111, and a signal line 130 and a side wiring 133 can be formed on the front surface 102 and the side surface 103 of the substrate 110 by printing, coating, etc. on the front surface 101 and the first side surface 1031 of the substrate 110, respectively. The side wiring 133 is arranged on the arc-shaped protrusion 111 on the side surface 103, wherein the signal line 130 and the side wiring 133 can be a conductive material such as metal or indium tin oxide (ITO). It should be noted that the display unit 120 can be transferred to the front surface 101 of the substrate 110 after preparation, or it can be directly formed on the front surface 101 of the substrate 110, and the embodiment of the present invention does not specifically limit this. If the panel 20 assembly includes only one display substrate, the display substrate is the first display substrate 100; if the panel 20 includes multiple display substrates, the first display substrate 100 can be spliced ​​and combined with other display substrates to form a panel assembly with a larger area.

[0038] Continue to refer Figure 2In the first display substrate 100, the front side 101 and the back side 102 of the substrate 110 can be connected through a first side surface 1031 provided with an arc-shaped protrusion 111. Compared with the situation in the prior art where the side surface of the substrate is a flat surface, the connection between the first side surface 1031 and the front side 101 of the substrate 110 and the back side 102 of the substrate 110 is relatively gentle, and there is no large angle. Therefore, the side wiring 133 can smoothly transition from the front side 101 of the substrate 110 to the back side 102 of the substrate 110 along the arc-shaped protrusion 111, avoiding the situation of breaking at the angle, thereby ensuring the integrity of the side wiring 133, improving the accuracy of signal transmission by the side wiring 133, and further improving the side wiring 133. The display effect of the display substrate is improved, the side wiring 133 is not easy to break and the service life of the side wiring 133 can be increased, thereby increasing the service life of the display substrate; one end of the side wiring 133 is electrically connected to at least part of the signal line 130 on the front side 101 of the substrate 110, and the other end extends along the arc-shaped protrusion 111 to the back side 102 of the substrate 110. The side 103 can be used to arrange the circuit, and the first side 1031 of the first display substrate 100 is used as a fan-out area. The frame size of the first display substrate 100 can be reduced, and the screen-to-body ratio of the display substrate 100 can be increased, so that the panel assembly with a larger area finally formed has a good display effect.

[0039] Optional, Figure 3 A schematic cross-sectional structure diagram of another panel assembly provided in an embodiment of the present invention is shown in FIG. Figure 3 As shown, the display unit 120 includes at least one light emitting element 121, and the light emitting element 121 includes but is not limited to mini LED or micro LED. At this time, the light emitting element 121 in the display substrate can be transferred to the front side 101 of the substrate 110 in the display substrate by mass transfer.

[0040] Exemplarily, the panel assembly 20 is a display screen with a larger size. The panel assembly 20 can be spliced ​​by multiple display substrates. The display substrate can have a smaller size. Compared with transferring all the light-emitting elements 121 to a display screen with a larger size at one time, the difficulty of transferring the light-emitting elements 121 to a display substrate with a smaller size at one time is reduced, which is conducive to reducing the preparation cost of the panel assembly 20 and improving the production yield of the panel assembly. When the light-emitting element 121 is a mini LED or a micro LED, a binding electrode should also be provided on the front side 101 of the substrate 110. The light-emitting element 121 of the light-emitting unit 120 is transferred to the front side 101 of the substrate 110 by mass transfer and is electrically connected to the binding electrode. Among them, the light-emitting element 121 may include a first pole 1201 and a second pole 1202, and the binding electrode may include a first binding electrode 1203 and a second binding electrode 1204. The first pole 1201 of the light-emitting element 121 is electrically connected to the first binding electrode 1203, and the second pole 1202 of the light-emitting element 121 is electrically connected to the second binding electrode 1204.

[0041] Optionally, in the same first display substrate, the arc-shaped protrusions are tangent to the front surface and the back surface respectively.

[0042] For example, Figure 4 A schematic cross-sectional structure diagram of another panel assembly provided in an embodiment of the present invention is shown in FIG. Figure 4 As shown, in the first display substrate 100, the arc-shaped protrusion 111 can be a semicircle, and the first side surface 1031 of the substrate 110 is designed as a semicircular protruding structure, and the front side 101 and the back side 102 of the substrate 110 are tangent to the arc-shaped protrusion 111, and a smooth transition is made from the front side 101 through the first side surface 1031 to the back side 102, without structural mutations and corners, so that the side wiring 133 set on the first side surface 1031 does not need to pass through a large angle, and can smoothly transition from the front side 101 through the side surface 1031 to the back side 102, and is not easy to break, so that the side wiring 133 is less likely to be damaged, further reducing the risk of poor signal contact. It should be noted that the arc-shaped protrusion 111 includes a semicircular structure, wherein the semicircular structure includes but is not limited to a semicircular structure of a perfect circle and / or an ellipse.

[0043] Optional, Figure 5 A schematic top view of another panel assembly provided in an embodiment of the present invention is shown. Figure 6 A schematic cross-sectional structure diagram of another panel assembly provided by an embodiment of the present invention, wherein: Figure 6 for Figure 5 The cross-sectional structure diagram with AA' as the cutting line in the top view structure diagram; Figure 5 and Figure 6The signal line 130 includes a first signal line 131; at least part of the display units 120 located in the same row share the first signal line 131; the back side 102 of the first display substrate 100 includes a scan drive circuit 140; the scan drive circuit 140 includes a plurality of scan drive units 141 arranged in cascade; the output end of each scan drive unit 141 is electrically connected to each first signal line 131 one by one through different side wirings 133.

[0044] For example, Figure 5 The X direction in the figure is the row direction. The display units 120 in the same row may share the same first signal line 131. The first signal line 131 may be, for example, a scanning signal line. In this case, the first signal line 131 is used to transmit a scanning signal, and the pixel circuit of the display unit 120 may include a corresponding transistor. When the scanning signal transmitted by the first signal line 131 is at an enable level, the transistors of the pixel circuits of the display units 120 sharing the first signal line 131 may be turned on, so that the corresponding signal can be written into the display unit 120. Among them, the scanning signal transmitted by the first signal line 131 is provided by the scanning driving circuit 140. By setting the scanning driving circuit 140 on the side of the back side 102 of the substrate 110, the output end of each scanning driving unit 141 of the scanning driving circuit 140 is electrically connected to each first signal line 131 one by one through different side wirings 133. By controlling the scanning driving units 141 in the scanning driving circuit 140 to output the enable level of the scanning signal in sequence, and the scanning signals output by different scanning driving units 141 are respectively transmitted to each first signal line 131 through different side wirings 133, so that when the transistor of the pixel circuit of the display unit 120 receives the enable level of the scanning signal, it can control the corresponding signal to be written into the display unit 120, so as to control the display unit 120 to display light.

[0045] It should be noted that when the number of display units 120 in the same row is small, a row of display units can share one first signal line 131 and one scan drive unit 141; when the number of display units 120 in the same row is large, a row of display units can correspond to multiple first signal lines 131 and multiple scan drive units 141. For example, a row of display units corresponds to two first signal lines 131 and two scan drive units 141. A part of the display units 120 in the same row is electrically connected to the output end of one scan drive unit 141 through one of the first signal lines 131, and another part of the display units 120 is electrically connected to another scan drive unit 141 through another first signal line 131. The design can be made according to actual needs, and the embodiment of the present invention does not specifically limit this.

[0046] In an embodiment of the present invention, by allowing at least part of the display units located in the same row to share the first signal line, the number of signal lines arranged on the front side of the substrate in the display substrate is reduced, and the space utilization rate of the front side of the substrate in the display substrate can be improved; at the same time, the scanning drive circuit in the first display substrate is arranged on the back side of the substrate, and the first signal line on the front side is electrically connected to each scanning drive unit in the scanning drive circuit on the back side through the side wiring, so as to further improve the space utilization rate of the first display substrate on the basis of ensuring normal display, reduce the frame size of the first display substrate, and improve the screen-to-body ratio of the display substrate.

[0047] It is understandable that the pixel circuit of the display unit may include one or more transistors, and may also include other active devices and / or passive devices, which is not specifically limited in the embodiment of the present invention. Among them, the transistor of the pixel circuit may be an N-type transistor or a P-type transistor; when it is an N-type transistor, the enable level of the scan signal is a high-level signal, and when it is a P-type transistor, the enable level of the scan signal is a low-level signal, which is not specifically limited in the embodiment of the present invention.

[0048] Optional, Figure 7 A schematic cross-sectional structure diagram of another panel assembly provided by an embodiment of the present invention, wherein: Figure 7 for Figure 5 The cross-sectional structure diagram with BB' as the cutting line in the top view structure diagram; Figure 5 and Figure 7 The signal line 130 includes a second signal line 132; at least part of the display units 120 located in the same column share the second signal line 132; the back side of the first display substrate includes a driver chip setting area 150; the driver chip setting area 150 is used to set a driver chip 151; the driver chip 151 includes at least one signal output terminal; each signal output terminal is electrically connected to each second signal line 132 one by one through different side wirings 133.

[0049] For example, Figure 5The Y direction in the figure is the column direction for illustration. The display units 120 in the same column may share the same second signal line 132, and the second signal line 132 may include, for example, at least one of a data line, a positive power line, and a negative power line. The second signal line 133 may transmit a driving signal to at least part of the display units 120 in one or more columns, so that at least part of the display units 120 in the same column may display and emit light according to the driving signal received. The driver chip setting area 150 and the driver chip 151 are arranged on the back side 102 of the substrate 110, and each signal output terminal on the driver chip 151 is electrically connected to different side wirings 133, respectively. The driving signal of the driver chip 151 can transmit the driving signal to the second signal lines 132 of different columns through the connected signal output terminals and the side wirings 133, so that at least part of the display units 120 in the same column may display and emit light according to the driving signal received.

[0050] It should be noted that, when the number of display units 120 in the same column is small, the display units in one column may share one second signal line 132; when the number of display units 120 in the same column is large, the display units in one column may correspond to multiple second signal lines 132. Taking one column of display units corresponding to two second signal lines 132 as an example, a part of the display units 120 in the same column share one of the second signal lines 132, and another part of the display units 120 share the other second signal line 132. The two second signal lines 132 are evenly driven and electrically connected to the chip 151, which can be designed according to actual needs. The embodiment of the present invention does not make any specific limitation to this.

[0051] In an embodiment of the present invention, by making at least part of the display units located in the same column share the second signal line, the number of signal lines arranged on the front side of the substrate in the display substrate is reduced, thereby improving the space utilization rate of the front side of the substrate in the display substrate; at the same time, the driver chip setting area in the first display substrate is set on the back side of the substrate, and the second signal line on the front side is electrically connected to each signal output terminal of the driver chip through the side wiring, so as to further improve the space utilization rate of the first display substrate on the basis of ensuring normal display, reduce the frame size of the short first display substrate, and improve the screen-to-body ratio of the display substrate. The side of the substrate can be used as a fan-out area, thereby further reducing the frame size of the display substrate and improving the display effect of the panel assembly.

[0052] It can be understood that the first signal line and the second signal line can exist on the front side of the display substrate at the same time. In this case, the side of the display substrate should include at least two first side sides; alternatively, the first signal line and the second signal line can also be respectively arranged on different display substrates. In this case, the side of the display substrate can include at least one first side side; accordingly, the scanning drive circuit and the drive chip can also be simultaneously arranged on the same display substrate, and both are arranged on the back side of the substrate of the same display substrate, or they can be respectively arranged on different display substrates, or partially arranged on the back side of the substrate. The embodiment of the present invention does not make specific limitations on this.

[0053] Optional, Figure 8 A schematic cross-sectional structure diagram of another panel assembly provided in an embodiment of the present invention is shown in FIG. Figure 8 As shown, the display substrate of the panel assembly 20 also includes a second display substrate 200; the multiple side surfaces 203 of the second display substrate 200 include at least one second side surface 2032; the second side surface 2032 encloses an arc-shaped groove 212; in the adjacent first display substrate 100 and second display substrate 200, the arc-shaped groove 212 of the second display substrate 200 covers the arc-shaped protrusion 111 of the first display substrate 100.

[0054] Exemplarily, the front side 201 of the substrate 210 of the second display substrate 200 and the front side 101 of the substrate 110 of the first display substrate 100 are located on the same side, and the display unit 220 and at least part of the signal line 230 of the second display substrate 200 are located on the front side 201 of the substrate 210. The second side surface 2032 of the second display substrate 200 can be spliced ​​with the first side surface 1031 of the first display substrate 100, so that the second display substrate 200 and the first display substrate 100 are spliced ​​to form a panel assembly with a larger area. The arc-shaped groove 212 of the second side surface 2032 can be aligned and engaged with the arc-shaped protrusion 111 of the first side surface 1031, so that the second display substrate 200 and the first display substrate 100 are seamlessly spliced ​​together, thereby improving the display effect of the spliced ​​panel assembly. Moreover, the arc-shaped groove 212 of the second side surface 2032 can cover the side wiring 133 on the surface of the first side surface 1031, protect the side wiring 133, and make it less likely to be damaged, thereby ensuring that the spliced ​​panel assembly can accurately display the corresponding picture and ensuring that the final spliced ​​display panel has a good display effect.

[0055] Optional, Fig. 9 A schematic cross-sectional structure diagram of another panel assembly provided in an embodiment of the present invention is shown in FIG. Fig. 9 As shown, the panel assembly 20 further includes at least one connecting line 1212 ; the signal lines 130 of the adjacent first display substrate 100 and the signal lines 230 of the adjacent second display substrate 200 are electrically connected to each other through the connecting line 1212 .

[0056] Exemplarily, the second display substrate 200 is assembled with the first display substrate 100, and the signal line on the front side of the second display substrate 200 can be electrically connected to the side wiring 133 of the first display substrate 100 through the connecting line 1212, and the signal line 130 of the first display substrate 100 is also electrically connected to the side wiring 133 of the first display substrate 100, so that the signal line 130 of the adjacent first display substrate 100 and the signal line 230 of the second display substrate 200 are both electrically connected to the side wiring 133 of the first display substrate 100. At this time, the second display substrate 200 can share the substrate 10 disposed in the first display substrate 100 with the first display substrate 100. The scanning driving circuit 140, the driving chip 151, etc. on the back side 102 enable the scanning driving circuit 140 and / or the driving chip 151 to receive the corresponding signal through the side wiring 133 of the first display substrate 100, and transmit it to the respective display units (120, 220) through the side wiring 133 and the signal line (130, 230), thereby eliminating the need to set wiring on the side surface 203 of the second substrate 200, and eliminating the need to set scanning driving circuits, driving chips and other circuits on the back side 202 of the substrate 210 in the second display substrate 200, thereby improving the space utilization rate of the second display substrate 200, reducing the frame of the second display substrate 200, and improving the screen-to-body ratio of the display substrate. At the same time, the adjacent first display substrate 100 and the second display substrate 200 use the same scanning driving circuit 140 and / or driving chip 240, so that the same scanning driving circuit 140 and / or driving chip 240 can simultaneously control the display unit 130 of the adjacent first display substrate 100 and the display unit 230 of the second display substrate 200 to display light, so that the display unit 130 and the display unit 230 can receive the same signal, thereby improving the consistency of the display light brightness of the first display substrate 100 and the second display substrate 200, improving the display uniformity of different display substrates, and then improving the display effect of the spliced ​​panel assembly.

[0057] It is understandable that the signal line located on the front side of the second display substrate can also be directly electrically connected to the signal line on the front side of the first display substrate through a connecting line. In this case, the signal line of the second display substrate can still share the scanning drive circuit, drive chip, etc. with the signal line of the first display substrate.

[0058] Optional, Fig.10 A schematic cross-sectional structure diagram of another panel assembly provided in an embodiment of the present invention is shown in FIG. Fig.10As shown, the signal line 130 of the first display substrate 100 includes a first power signal line 1301, and the signal line 230 of the second display substrate 200 includes a second power signal line 2301; the plurality of display units 220 of the second display substrate 200 include a first display unit 221 close to the second side surface 2032; the first display unit 221 includes a first light-emitting element 123 and a first pixel circuit (not shown in the figure); the first electrode 1231 of the first light-emitting element 123 is electrically connected to the first pixel circuit located on the front surface 201 of the substrate 201 in the second display substrate 200, and the second electrode 1232 of the first light-emitting element 123 is electrically connected to the first power signal line 1301 of the first display substrate 100. Accordingly, the front surface 201 of the substrate 210 of the second display substrate 200 should be provided with a first binding electrode electrically connected to the first electrode 1231, and the front surface 101 of the substrate 110 of the first display substrate 100 should be provided with a second binding electrode electrically connected to the second electrode 1232.

[0059] Exemplarily, the first display unit 221 of the second display substrate 200 is located on the front side 201 close to the side of the first display substrate 100 adjacent to the second display substrate 200, the first electrode 1231 of the first light-emitting element 123 is electrically connected to the first pixel circuit in the second display substrate 200, and the second electrode 1232 of the first light-emitting element 123 is electrically connected to the power signal 1301 of the first display substrate 100 through the side wiring 133. At this time, the first pixel circuit can provide a corresponding electrical signal to the first electrode 1231 of the first light-emitting element 123, and the second electrode 1232 of the first light-emitting element 123 can receive the power signal transmitted by the power signal line 1301 in the first display substrate 100, so that the first light-emitting element 123 can display and emit light according to the signals received by its first electrode 1231 and the second electrode 1232.

[0060] It is understandable that a plurality of first display units 221 may be provided on the front side 201 of the second display substrate 200, close to the first display substrate 100 adjacent thereto, and the first light-emitting elements 123 of the plurality of first display units 221 are sequentially arranged at the joint of the second display substrate 200 and the first display substrate 100, so that the joint can be displayed, the screen-to-body ratio is improved, and the panel assembly 20 after the joint has a good display effect at the joint, thereby improving the display continuity and integrity of the panel assembly after the joint. There may be some height differences between the front side 101 of the first display substrate 100 and the front side 201 of the second display substrate 200, and the embodiments of the present invention do not specifically limit how to make up for these height differences.

[0061] Optional, Fig.11 A schematic cross-sectional structure diagram of another panel assembly provided in an embodiment of the present invention is shown in FIG. Fig.11As shown, the display substrate of the panel assembly 20 includes at least two second display substrates 200 and at least one first display substrate 100; the first display substrate 100 is located between two adjacent second display substrates 200; the multiple side surfaces 103 of the first display substrate 100 include at least two first side surfaces 1031; the arc-shaped grooves of different second display substrates 200 adjacent to the same first display substrate 100 respectively cover the arc-shaped protrusions of different first side surfaces 1031 in the first display substrate 100. In this way, at least three display substrates can be nested and spliced ​​together, and the first display substrate 100 and the second display substrate 200 are seamlessly spliced ​​together. The second display substrates 200 on both sides can share the scanning drive circuit, drive chip, etc. with the first display substrate 100 in the middle, thereby improving the screen-to-body ratio of the display substrate and the display effect of the panel assembly after splicing.

[0062] Optional, continue to refer to Fig.11 , the second display substrates 200 on both sides are edge display substrates 300 in the panel assembly 20; the multiple side surfaces 303 of the edge display substrate 300 include a third side surface 3033 away from other display substrates; the third side surface 3033 is perpendicular to the front surface 301. It can be understood that the display substrate closest to the edge of the panel assembly is the edge display substrate, regardless of whether it is the first display substrate and / or the second display substrate. In this way, the third side surface of the edge display substrate of the panel assembly is designed to be a flat surface, which facilitates the assembly of the panel assembly 200 and improves the aesthetics of the panel assembly 200.

[0063] Optional, Fig.12 A schematic cross-sectional structure diagram of another panel assembly provided in an embodiment of the present invention is shown in FIG. Fig.12 As shown, the display substrate of the panel assembly 20 includes at least two first display substrates 100 and at least one second display substrate 200; the second display substrate 200 is located between two adjacent first display substrates 100; the multiple side surfaces 203 of the second display substrate 200 include at least two second side surfaces 2032; the arc-shaped grooves of different second side surfaces 203 in the second display substrate 200 respectively cover the arc-shaped protrusions of different first display substrates 100 adjacent to the second display substrate 200.

[0064] In this way, at least three display substrates can be nested and spliced ​​together, and the first display substrate 100 and the second display substrate 200 can be seamlessly spliced ​​together. The second display substrate 200 in the middle can share the scanning drive circuit, drive chip and other circuits with the first display substrates 100 on both sides, thereby improving the screen-to-body ratio of the display substrate and the display effect of the spliced ​​display panel. Fig.10, the first display substrates 100 on both sides are edge display substrates 300 in the panel assembly 20 ; the multiple side surfaces 303 of the edge display substrate 300 include a third side surface 3033 away from the other display substrates; the third side surface 3033 is perpendicular to the front surface 301 .

[0065] Optional, Fig.13 A schematic cross-sectional structure diagram of another panel assembly provided in an embodiment of the present invention is shown in FIG. Fig.13 As shown, the multiple side surfaces 103 of the first display substrate 100 also include at least one second side surface 1032; the second side surface 1032 includes an arc-shaped groove; among two adjacent first display substrates 100, the arc-shaped groove of one first display substrate 100 covers the arc-shaped protrusion of the other first display substrate 100. Exemplarily, taking the panel assembly 20 including three first substrates 100 as an example, the arc-shaped protrusion of the first side surface 1031 of the left first substrate 100 can be seamlessly spliced ​​with the arc-shaped groove of the second side surface 1032 of the middle first substrate 100, and the arc-shaped protrusion of the first side surface 1031 of the middle first substrate 100 can be seamlessly spliced ​​with the arc-shaped groove of the second side surface 1032 of the right first substrate 100. In this way, at least two display substrates can be nested and spliced ​​together with only the same type of display substrate, which simplifies the types of display substrates and production and reduces production costs.

[0066] For example, Fig.14 A schematic cross-sectional structure diagram of another panel assembly provided in an embodiment of the present invention is shown in FIG. Fig.14 As shown, taking the panel assembly 20 including three first substrates 100 as an example, the first display substrate 100 on the left and the first display substrate 100 on the right are both edge display substrates 300, and the side away from other display substrates among the multiple side surfaces 303 of the edge display substrate 300 is the third side surface 3033; the third side surface 3033 is perpendicular to the front surface 301. It can be understood that in the same display substrate, its multiple side surfaces may include one or more of the first side surface, the second side surface, and the third side surface, and each type is not limited to one.

[0067] For example, Fig.15 A schematic cross-sectional structure diagram of another panel assembly provided in an embodiment of the present invention is shown in FIG. Figure 5 As shown, taking the panel assembly 20 including four display substrates as an example, it can be Fig.13In the form where the first display substrate 100 and the second display substrate 200 are alternately adjacent, if the first display substrate 100 is adjacent to one second display substrate 200, the first display substrate 100 includes at least one first side surface 1031; if the first display substrate 100 is adjacent to two second display substrates 200, the first display substrate 100 includes at least two first side surfaces 1031, and the arc-shaped protrusion of the first side surface 1031 can be seamlessly spliced ​​with the arc-shaped groove of the second display panel 200; if the second display substrate 200 is adjacent to one first display substrate 100, the second display substrate 200 includes at least one second side surface 2032; if the second display substrate 200 is adjacent to two first display substrates 100, the second display substrate 200 includes at least two second side surfaces 2032, and the arc-shaped groove of the second side surface 2032 can be seamlessly spliced ​​with the arc-shaped protrusion of the first display panel 100. It can be understood that the first display panel 100 includes one or more first side surfaces 1031. When the first display panel 100 includes multiple first side surfaces 1031, the first side surfaces 1031 can be located on adjacent side surfaces or on opposite side surfaces. The embodiment of the present invention does not specifically limit this. The same applies to the second side surface 2032 of the second display panel 200.

[0068] For example, continue to refer to Fig.15 The panel assembly 20 includes multiple display substrates; the display substrate closest to the edge of the panel assembly 20 among the multiple display substrates is the edge display substrate 300; the multiple side surfaces 303 of the edge display substrate 300 include a third side surface 3033 away from other display substrates; the third side surface 3033 is perpendicular to the front surface 301.
