In this embodiment, the display panel includes a first substrate 100 and a second substrate 200 disposed opposite to each other, and the pixel array 210 is located between the first substrate 100 and the second substrate 200. It is understood that the first substrate 100 is a set of layers on a side of the pixel array 210 facing away from the second substrate 200, and the second substrate 200 is a set of layers on a side of the pixel array 210 facing away from the first substrate 100, and it is apparent that a step region exists in the second substrate 200 with respect to the first substrate 100. For example, the display panel is an organic light emitting display panel, the second substrate is an array substrate, the array substrate comprises an array metal layer, an interlayer insulating layer and the like, the first substrate is a packaging substrate, and the packaging substrate comprises a packaging layer, a protective layer and the like; or the display panel is a liquid crystal display panel, the second substrate is an array substrate, the array substrate comprises an array metal layer, an interlayer insulating layer and the like, the first substrate is a color film substrate, and the color film substrate comprises a color resistance layer, a black matrix and the like; embodiments of the invention are not limited in this respect.

The pixel array 210 includes a plurality of pixel units 211, only 2 × 2 pixel units 211 are shown in the display area 10 of fig. 1, and each pixel unit 211 includes a pixel circuit 211a and a light emitting element 211b electrically connected to the pixel circuit 211 a. The pixel units 211 in an optional row are electrically connected to the same scan line 212, the pixel units 211 in a column are electrically connected to the same data line 213, the scan line 212 controls the pixel circuits 211a of the pixel units 211 in a row to be turned on, and the data line 213 provides a data signal to the light emitting element 211b through the turned-on pixel circuits 211a, so that the light emitting element 211b emits light. It is to be understood that the wiring pattern and the pixel arrangement pattern of the pixel array 210 in the drawings are only a simple example, and the wiring pattern and the pixel arrangement pattern of the pixel array 210 of the display panel may be various in practice, but are not limited thereto.

In this embodiment, the display panel includes a display area 10 and a non-display area 20, wherein the area where the pixel array 210 is located is the display area 10 of the display panel, the area for wiring at the periphery of the pixel array 210 is the non-display area 20, and the data line 213 of the pixel array 210 extends to the non-display area 20. The fan-out area 21 of the non-display area 20 includes a plurality of signal traces 230, and the signal traces 230 are selected to provide data signals for the data lines 213.

The non-display region 20 is provided with a sealing structure 220, the sealing structure 220 surrounding at least the display region 10, the sealing structure 220 being disposed between the first substrate 100 and the second substrate 200 for sealing the display region 10 to prevent impurities or air from entering the display region 10. For example, the display panel is an organic light emitting display panel, the whole display area is covered by the sealing structure, and the optional sealing structure is a thin film packaging layer; for example, the display panel is a liquid crystal display panel, the sealing structure is located in the non-display area, and the optional sealing structure is frame sealing glue. It is understood that the signal traces 230 of the fan-out area 21 extend to the outside of the sealing structure 220 and are electrically connected to peripheral circuits, which optionally include the driving chip 300.

The fan-out region 21 is provided with a plurality of signal traces 230 connected to the pixel array 210, it can be understood that the plurality of signal traces 230 in the fan-out region 21 at least include a plurality of signal traces 230 electrically connected to the plurality of data lines 213 correspondingly, the signal traces 230 provide data signals for the data lines 213 electrically connected correspondingly, and optionally, the plurality of signal traces in the fan-out region further include other functional signal traces, such as signal traces providing timing signals, without being limited thereto.

The plurality of signal traces 230 in the fan-out area 21 are electrically connected to the driver chip 300, and in the arrangement direction X of the plurality of signal traces 230, the fan-out area 21 includes a plurality of trace concentration areas 21b and a plurality of support areas 21c arranged at intervals, and the plurality of signal traces 230 are distributed in the plurality of trace concentration areas 21 b. The fan-out area 21 further includes a plurality of first spacers 110, the first spacers 110 being supported between the first substrate 100 and the second substrate 200, the plurality of first spacers being located at an outer side of the sealing structure 220, the outer side of the sealing structure 220 being a side of the sealing structure 220 facing away from the display area 10. In this embodiment, a gap between two adjacent routing concentration areas 21b serves as a supporting area 21c, and the plurality of first spacers 110 are distributed in the plurality of supporting areas 21c, so that a standing area of the first spacer 110 is vacated between two adjacent routing concentration areas 21b, which is convenient for placing the first spacer 110.

As described above, the second substrate 200 has the step region with respect to the first substrate 100. At least two cuts are required in the process of manufacturing the display panel, the first cut is to form the second substrate 200, and the second cut is to form the first substrate 100, it can be understood that the cutting line a-a 'of the first substrate 100 overlaps with the fan-out region 21 of the second substrate 200, and fig. 1 and 2 are completed display panels, wherein the first substrate 100 is formed by cutting along the cutting line a-a' in the manufacturing process.

In this embodiment, the first spacer 110 is disposed between the first substrate 100 and the second substrate 200 and outside the sealing structure 220, and the first spacer 110 is close to the cutting line of the first substrate 100. Based on this, the first spacer 110 may support the first substrate 100 and the second substrate 200 at the cutting line a-a 'during the cutting of the cutter wheel along the cutting line a-a' to form the first substrate 100. The substrate at the cutting line A-A' is supported, so that the situation that the substrate is broken by the cutter wheel without support at the cutting position can be avoided, and the problem that the substrate is broken to damage a film layer on the substrate or wires is correspondingly avoided.

Each signal of optionally walking in the line concentration district is walked the line and is distributed according to equidistant mode, perhaps, walks each signal of walking in the line concentration district and walks the line and distribute according to unequal interval mode, perhaps, many signals walk line evenly distributed and concentrate the district at a plurality of lines. In this embodiment, each signal trace 230 of the fan-out area 21 is distributed in the trace concentration area 21b, a standing position can be made for the first spacer 110 at a position close to the cutting line of the first substrate, each signal trace 230 in the trace concentration area 21b can be distributed at equal intervals or at unequal intervals, and the number of the signal traces 230 distributed in different trace concentration areas 21b can be the same or different, and is not specifically limited. In order to ensure that the first spacer 110 can be disposed in the supporting area 21c, the distance between two signal traces 230 located in two adjacent trace concentration areas 21b must be greater than the maximum dimension of the first spacer 110 along the X direction.

It should be noted that a plurality of first spacers may be distributed in each support area; optionally, a plurality of first spacers can be distributed in part of the supporting area, and the rest of the supporting area is not provided with the first spacers; the distribution position of the first shock insulator can be reasonably designed according to the requirement of the product by related practitioners.

Exemplarily, on the basis of the above technical solution, referring to fig. 4, a partial schematic view of the display panel before cutting is shown. As shown in fig. 1 to fig. 4, the optional signal trace 230 includes a diagonal portion 231 and a straight portion 232, which are electrically connected, an extending direction of the diagonal portion 231 intersects an extending direction of the straight portion 232, and the straight portions 232 in the signal trace 230 are distributed in the trace concentration area 21 b. The extending direction of the oblique line 231 in the signal trace 230 intersects with the cutting line a-a' and forms an included angle other than 90 °, which can also be understood as the extending direction of the oblique line 231 intersects with the data line 213 and forms a larger acute angle or obtuse angle; while the extending direction of the straight portion 232 in the signal trace 230 is perpendicular to the cutting line a-a', it can also be understood that the extending direction of the straight portion 232 is substantially consistent with the data line 213 or the included angle is very small and negligible. The straight portions 232 of the signal traces 230 are distributed in the trace concentration areas 21b, and the first spacer 110 is located in the supporting areas 21c vacated by the trace concentration areas 21b distributed by the straight portions 232.

If the oblique line part of the signal wiring is distributed in the wiring concentration area, and the area vacated between the adjacent wiring concentration areas is a supporting area, the shock insulator is positioned in the supporting area vacated by the plurality of wiring concentration areas distributed by the oblique line part, and in order to vacate a certain standing space for the shock insulator between the signal wiring, the slopes of two different oblique line parts may be different, so that the wiring difficulty of the oblique line part can be obviously increased. In this embodiment, the first spacer 110 is located in the supporting area 21c vacated by the plurality of routing concentration areas 21b distributed by the linear portions 232, and the extending directions of the linear portions 232 are the same, which greatly reduces the wiring difficulty.

The first spacer 110 is located in the supporting region 21c vacated by the plurality of routing concentration regions 21b distributed by the straight line portions 232, so that the number of the oblique line portions 231 is not affected by the first spacer 110 when the fan-out region 21 arranges the signal routing 230, and the routing mode can meet the routing requirement of the high-resolution display panel; the high resolution is realized, meanwhile, the frame area is not excessively occupied, and the narrow frame is realized.

The first spacers 110 may be distributed at equal intervals along the X direction, and the first spacers 110 of the two adjacent

first substrates

100a and 100b may be distributed symmetrically along the axis of the cutting line a-a ', so that when the cutter wheel cuts the two adjacent

first substrates

100a and 100b, the first spacers 110 distributed at equal intervals along the X direction may effectively share the cutter wheel cutting pressure, and the first spacers 110 distributed symmetrically along the axis of the cutting line a-a' may balance the cutter wheel cutting pressure on the two adjacent

first substrates

100a and 100b, so that the cutter wheel cutting pressures on the two adjacent

first substrates

100a and 100b are substantially the same. The substrate can be prevented from being broken due to uneven cutting pressure of the cutter wheel.

The straight line parts in the optional routing concentration area are distributed in an equal-spacing mode, or the straight line parts in the routing concentration area are distributed in parallel in an unequal-spacing mode. In this embodiment, the straight portions 232 of the signal traces 230 in the fan-out area 21 are distributed in the trace concentration area 21b, and a standing position may be left for the first spacer 110 at a position close to the cutting line a-a' of the first substrate 100, where the arrangement manner of the straight portions in the trace concentration area is not particularly limited. In order to ensure that the first spacer 110 can be disposed in the supporting area 21c, the distance between the two straight portions 232 of two adjacent trace concentration areas 21b must be greater than the maximum dimension of the first spacer 110 in the X direction.

The oblique line parts of the plurality of selectable signal wires are non-uniformly distributed in an unequal-spacing mode. In this embodiment, the diagonal portions 231 of the signal traces 230 are non-uniformly distributed in an unequal-pitch manner, so that the wiring arrangement of the diagonal portions 231 is flexibly designed, thereby being capable of meeting the requirements of different user products. The diagonal parts 231 are flexibly designed in wiring arrangement, the requirements of different linear part 232 distances can be met, and the wiring design difficulty of the fan-out area 21 is reduced.

Optionally, the first spacers are uniformly distributed in the support areas. As shown in fig. 3 and 4, the first spacers 110 are uniformly distributed in the plurality of support areas 21c, and the distance between two adjacent first spacers 110 is a preset distance along the arrangement direction X of the signal trace 230, so that the first spacers 110 not only play a role of supporting, but also can uniformly share the cutting pressure of the cutter wheel in the X direction. In addition, the first spacers 110 are uniformly distributed in the plurality of support areas 21c, so that the first spacers 110 of two adjacent first substrates are symmetrically distributed along the cutting line a-a', which can balance the cutting pressure of the cutter wheel on the two adjacent first substrates and prevent the substrates from being cracked due to uneven pressure of the cutter wheel.

Exemplarily, on the basis of the above technical solution, referring to fig. 5, a schematic diagram of another display panel provided in an embodiment of the present invention is shown. As shown in fig. 5, the optional display area 10 includes a plurality of main spacers 121 and auxiliary spacers 122; the size of the auxiliary spacers 122 is smaller than that of the main spacers 121 in a direction perpendicular to the plane of the display panel. In this embodiment, the display area 10 includes a plurality of main spacers 121 and auxiliary spacers 122, the main spacers 121 play a main supporting role, and the auxiliary spacers 122 play an auxiliary supporting role, so as to support the first substrate 100 and the second substrate 200, so that the thickness of the display panel is uniform. It is understood that the size, position, number and other parameters of the main and auxiliary spacers shown in fig. 5 are only a simple example, and in practical production, the size, position, number and other parameters are not limited thereto, and for example, the main spacers in the display area may be in direct contact with a certain layer of the pixel unit, rather than being located at the gap between adjacent pixel units.

The size of the first spacer 110 is the same as that of the main spacer 121, optionally in a direction perpendicular to the plane of the display panel; alternatively, in other embodiments, the size of the optional first spacer is the same as the size of the auxiliary spacer. The main spacer 121 and the first spacer 110 outside the sealing structure are fabricated in the same process, or in other embodiments, the auxiliary spacer and the first spacer outside the sealing structure are fabricated in the same process without adding an additional first spacer process.

Fig. 6 is a schematic view of another display panel according to an embodiment of the present invention. As shown in fig. 6, the maximum size of the first spacer 110 is larger than the maximum size of the main spacer 121, optionally in a direction parallel to the plane of the display panel; alternatively, the maximum dimension of the first spacer 110 is greater than the maximum dimension of the auxiliary spacer 122.

In this embodiment, the first spacer 110 is located outside the sealing structure 220 and plays a role of supporting the first substrate 100 and the second substrate 200, and on this basis, the first spacer 110 also needs to bear the cutting pressure of the cutter wheel, so the first spacer 110 needs to have a stronger supporting capability. The main spacers 121 and the auxiliary spacers 122 of the display area 10 are more in number, and only function to support the first substrate 100 and the second substrate 200, so as to improve the uniformity of the cell thickness of the display panel without bearing extra large pressure.

Based on this, in the direction parallel to the plane of the display panel, the size of the first spacer 110 is larger than that of the spacer in the display area 10, the supporting capability of the first spacer 110 is enhanced relative to that of the spacer in the display area 10, the first substrate 100 and the second substrate 200 are effectively supported at the cutting position, and the substrate is prevented from being broken when being cut due to insufficient support.

Exemplarily, on the basis of the above technical solution, referring to fig. 7, a partial schematic view of another display panel provided in an embodiment of the present invention is shown, and fig. 8 is a cross-sectional view taken along B-B' of fig. 7. As shown in fig. 7 and 8, an optional first spacer 110 is fixedly disposed on a side of the first substrate 100 facing the second substrate 200, and a second spacer corresponding to the first spacer 110 is fixedly disposed on a side of the second substrate 200 facing the first substrate 100; the second spacer includes at least one position-limiting portion 241, the position-limiting portion 241 is located between the first spacer 110 and the sealing structure 220, and the position-limiting portion 241 is disposed in contact with the first spacer 110 in a direction parallel to the plane of the display panel.

Referring to fig. 9, a partial schematic view of another display panel according to an embodiment of the present invention is shown, and fig. 10 is a cross-sectional view taken along line C-C' of fig. 9. As shown in fig. 9 and 10, the position-limiting portion 241 may at least partially overlap with the first spacer 110, optionally in a direction perpendicular to the plane of the display panel.

As in the above-mentioned embodiment, the first spacer 110 is fixedly disposed on the side of the first substrate 100 facing the second substrate 200, the end surface of the first spacer 110 facing the second substrate 200 is not fixedly connected to the second substrate 200, the position-limiting portion 241 is fixedly disposed on the side of the second substrate 200 facing the first substrate 100, and after the first substrate 100 and the second substrate 200 are packaged, the position-limiting portion 241 is located between the first spacer 110 and the sealing structure 220.

When the knife wheel cuts the upper substrate, at the position of the cutting line a-a', the cutting pressure of the knife wheel presses the upper substrate to bend it toward the lower substrate, and the first spacers 110 located in the area of the first substrate 100a may slide toward the sealing structure 220 of the first substrate 100a, and the first spacers 110 located in the area of the first substrate 100b may slide toward the sealing structure 220 of the first substrate 100 b. At this time, in the direction parallel to the plane of the display panel, the position-limiting portion 241 between the first spacer 110 and the sealing structure 220 is disposed in contact with or at least partially overlapped with the first spacer 110, so as to effectively limit the side-sliding position and the side-sliding distance of the first spacer 110, and to block the side-sliding of the first spacer 110.

Based on this, the sideslip of the first spacer 110 is limited, so that the first spacer 110 can play an effective supporting role, and the phenomenon that the signal routing is possibly damaged due to the sideslip of the first spacer 110 can be avoided.

The side of the optional limiting part, which is contacted with the first spacer, is a plane, or a concave surface formed by multiple planes, or a convex surface. As shown in fig. 7, one side of the optional limiting portion 241 contacting the first spacer 110 is a plane. As shown in fig. 9, one side of the optional position-limiting portion 241 contacting the first spacer 110 is a concave surface, and the shape of the concave surface can be matched with the first spacer 110 to perform an effective position-limiting function. Referring to fig. 11, which is a schematic diagram of relative positions of a first spacer and a position-limiting portion according to an embodiment of the present invention, as shown in fig. 11, a side of an optional position-limiting portion 241 contacting with the first spacer 110 is a concave shape formed by multiple planes. Referring to fig. 12, which is a schematic diagram illustrating relative positions of another first spacer and a limiting portion according to an embodiment of the present invention, as shown in fig. 12, one side of the optional limiting portion 241 contacting with the first spacer 110 is a convex surface, and two or more limiting portions 241 may be correspondingly disposed on one optional first spacer 110, so as to effectively limit the first spacer 110 from sliding laterally.

Referring to fig. 10, optionally, in a direction perpendicular to the plane of the display panel, a maximum contact size H1 of the limiting portion 241 with the first spacer 110 is greater than or equal to 1/3 of a size H2 of the first spacer 110. If the size of the limiting part in the direction perpendicular to the display panel is too small, the situation that the first spacer sideslips from the limiting part and passes under the cutting pressure of the cutter wheel can occur, and the limiting part cannot play an effective limiting role. The limiting portion 241 is designed reasonably along the dimension H1 perpendicular to the display panel, so that the limiting portion 241 plays a role of effectively limiting the first spacer 110, thereby avoiding the first spacer 110 from sideslipping and preventing the first spacer 110 from sideslipping to scratch the signal traces 230 or the film layer on the second substrate 200.

In other embodiments, the second spacer may further include two or more limiting portions, and for any one of the limiting portions, a side of the second spacer contacting the first spacer is a flat surface, a concave surface formed by multiple flat surfaces, or a convex surface. Related practitioners can reasonably design the number, size and position of the limiting parts corresponding to one first spacer according to the requirement of a product, and can also reasonably design the shape of one side, in contact with the first spacer, of each limiting part according to the requirement of the product, and it can be understood that the shapes of the limiting parts in the second spacer can be the same or different. Is not particularly limited.
