Description

Technical Field

[0001] An embodiment of the present disclosure relates to a display device. Background Art

[0002] Organic light-emitting diode (OLED) display devices have become a research hotspot and technology development direction for major manufacturers due to their advantages such as wide color gamut, high contrast, thin and light design, self-luminescence, bright colors, low power consumption and wide viewing angle.

[0003] The light-emitting principle of the organic light-emitting diode display device is as follows: the sub-pixels of the organic light-emitting diode display device include an anode, a cathode and an organic light-emitting layer located between the anode and the cathode; when light-emitting display is performed, electrons and holes are injected from the cathode and the anode into the electron transport layer and the hole transport layer respectively, and then the electrons and holes migrate from the electron transport layer and the hole transport layer to the organic light-emitting layer respectively, and meet in the organic light-emitting layer to form excitons and emit visible light.

[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0055] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The words "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. The words "include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0056] The features such as "parallel", "perpendicular" and "same" used in the embodiments of the present disclosure include the features such as "parallel", "perpendicular" and "same" in a strict sense, as well as the cases where "approximately parallel", "approximately perpendicular" and "approximately the same" contain certain errors, taking into account the errors associated with the measurement and the measurement of specific quantities (for example, the limitations of the measurement system), and are expressed as within the acceptable deviation range for a specific value determined by ordinary technicians in this field. For example, "approximately" can mean within one or more standard deviations, or within 10% or 5% of the value. When the number of a component is not specifically indicated in the following of the embodiments of the present disclosure, it means that the component can be one or more, or can be understood as at least one. "At least one" refers to one or more, and "multiple" refers to at least two. The "same layer" in the embodiments of the present disclosure refers to the relationship between multiple film layers formed by the same material after the same step (for example, a one-step patterning process). The "same layer" here does not always mean that the thickness of multiple film layers is the same or the height of multiple film layers in the cross-sectional view is the same.

[0057] In order to better utilize the space in the passenger compartment, enhance user experience, and achieve product differentiation, it has become a trend for vehicle-mounted display devices to adopt special-shaped (non-rectangular) designs. On the other hand, most car companies or products still require conventional rectangular-shaped vehicle-mounted display devices. In this case, in order to meet market needs, different mask plates need to be designed for vehicle-mounted display devices of different shapes, thereby increasing R&D costs and production costs.

[0058] For example, Figure 1 A schematic diagram of a vehicle-mounted display device with a special-shaped design; Figure 2 FIG. 1 is a schematic diagram of another vehicle-mounted display device using a rectangular design. Figure 1 As shown, the vehicle-mounted display device 10 includes a display panel 12, a COF 14 and a circuit board 16. The display panel 12 is rectangular in design, that is, the plane shape of the display panel 12 is rectangular; Figure 2 As shown, the vehicle-mounted display device 10 includes a display panel 12, a COF 14 and a circuit board 16. The display panel 12 is designed in a special shape, that is, the plane shape of the display panel 12 is a special shape. Figure 1 and Figure 2 As shown, since the shapes of the display areas of the two vehicle-mounted display devices are different, different mask plates are needed to produce devices or film layers such as pixel driving circuits, anode layers, and organic light-emitting layers, thereby increasing R&D costs and production costs.

[0059] Figure 3 for Figure 1 A partial structural schematic diagram of the vehicle-mounted display device shown; Figure 4 for Figure 2The schematic diagram of the partial structure of the vehicle-mounted display device is shown in FIG. Figure 3 As shown, the display panel 12 includes a display area 12A and a peripheral area 12B. The display area 12A includes a plurality of sub-pixels 20, and the peripheral area 12B includes a gate driving circuit unit GOA for providing gate driving signals to the sub-pixels 20 and a cathode line VSS for providing cathode signals. Figure 4 As shown, the display panel 12 also includes a display area 12A and a peripheral area 12B. The display area 12A includes a plurality of sub-pixels 20, and the peripheral area 12B includes a gate drive circuit unit GOA for providing gate drive signals to the sub-pixels 20 and a cathode line VSS for providing cathode signals. In addition, the peripheral area 12B of the display panel 12 also includes a plurality of leads 30 for electrically connecting the data lines of the plurality of sub-pixels 20 to the COF 14. Figure 3 The vehicle display device shown is different in that Figure 4 The display panel 12 in the vehicle-mounted display device shown adopts a special-shaped design, the corners of the display panel 12 are chamfered or cut, and the display area 12A of the display panel 12 is also special-shaped. At this time, the number of sub-pixels 20 in the sub-pixel rows corresponding to the corners of the display area 12 is small, resulting in uneven loads on the drive lines. Therefore, it is necessary to add an additional line compensation structure 40 to make the loads of the drive lines of the sub-pixel rows corresponding to the corners roughly the same as the loads of the drive lines of the sub-pixel rows in other areas; and this line compensation structure 40 will undoubtedly increase the border width of the display panel, resulting in a poor user experience.

[0060] In this regard, an embodiment of the present disclosure provides a display device, which includes a support layer and a display panel; the display panel includes a driving backplane and an encapsulation layer; the display panel includes a display portion and a bending portion, the bending portion is located at a corner of the display panel, the support layer is located on a side of the driving backplane of the display portion away from the encapsulation layer, and the bending portion is bent to a side of the support layer away from the display portion. Thus, the display device can bend a rectangular display panel into a special shape, thereby realizing a special-shaped design. Moreover, the display panel of the display device and a conventional rectangular display panel can share at least part of the mask plate, thereby greatly reducing the R&D and production costs.

[0061] The disclosed embodiment also provides a method for manufacturing a display device, which includes: forming a display panel, the display panel including a driving backplane and an encapsulation layer; arranging the display panel on the first side of the support layer, and bending the corner of the display panel toward the second side of the support layer, so that the portion of the display panel located on the first side of the support layer forms a display portion, and the portion of the display panel located on the second side of the support layer forms a bending portion. Thus, the method for manufacturing the display device can bend a rectangular display panel into a special shape, thereby realizing a special-shaped design. Moreover, the display panel in the manufacturing method and the conventional rectangular display panel can share at least part of the mask plate, thereby greatly reducing the R&D and manufacturing costs.

[0062] Hereinafter, the display device and the manufacturing method thereof provided by the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0063] Figure 5 A schematic plan view of a display device provided by an embodiment of the present disclosure; Figure 6 A display device provided by an embodiment of the present disclosure is Figure 5 Schematic diagram of the cross section of the AB line; Figure 7 The present invention provides a schematic plan view of a display panel in a display device provided in an embodiment of the present disclosure when the display panel is not bent.

[0064] like Figure 5 and Figure 6 As shown, the display device 200 includes a support layer 210 and a display panel 100; the display panel 100 includes a driving backplane 110 and an encapsulation layer 120; the display panel 100 includes a display portion 100A and a bending portion 100B, the bending portion 100B is located at a corner of the display panel 100, the support layer 210 is located on a side of the driving backplane 110 of the display portion 100A away from the encapsulation layer 120, and the bending portion 100B is bent to a side of the support layer 210 away from the display portion 100A. In other words, the bending portion 100B is located on the back of the display portion 100A, and a portion of the support layer 210 is located between the display portion 100A and the bending portion 100B. It should be noted that the bending portion 100B is connected to the display portion 100A and is two parts of the display panel 100; the bending portion 100B includes not only a curved portion, but also a flat portion located on the support layer 210 away from the display portion 100A; in addition, the embodiment of the present disclosure does not limit the number of bending portions, and the number of bending portions can be selected according to the required shape design. On the other hand, for simplicity, Figure 6 The display panel 100 only shows the driving backplane 110 and the encapsulation layer 120 , which serve as the bottom layer and the top layer of the display panel 100 , respectively.

[0065] In the display device provided by the embodiment of the present disclosure, the display portion of the display panel can be used as a display area to display images when in use, and the bent portion of the display panel does not display when in use. Thus, the display device can bend a rectangular display panel into a special shape, thereby realizing a special-shaped design. Moreover, the display panel of the display device can be rectangular when not bent, so it can share at least part of the mask plate with a conventional rectangular display panel, thereby greatly reducing the R&D and production costs.

[0066] like Figure 7 As shown, the planar shape of the display panel 100 when not bent is a rectangle; Figure 7After the two corners (i.e., the bending portions) are bent by the two bending lines 101 in the display panel 100, the display panel 100 can be formed into a special-shaped display panel. It should be noted that the above-mentioned bending line is the boundary between the display portion 100A and the bending portion 100B. It should be noted that although Figure 7 The two bending lines 101 in the display panel are straight lines, but the embodiments of the present disclosure include but are not limited to this. The bending lines can also be curves or folded lines, so as to realize more shapes of display parts. That is, the boundary line between the display part and the bending part of the display panel can be a straight line, a curve or a folded line.

[0067] In some examples, such as Figure 7 As shown, the display panel 100 includes a display portion 100A and bending portions 100B located at two corners of the display portion 100A. Of course, the embodiments of the present disclosure include but are not limited to this.

[0068] In some examples, such as Figure 7 As shown, the driving backplane 110 of the display portion 100A of the display panel 100 includes a plurality of first pixel driving circuits 115A, and the driving backplane 110 of the bending portion 100B of the display panel 100 includes a plurality of second pixel driving circuits 115B, and the plurality of second pixel driving circuits 115B and some of the first pixel driving circuits 115A are connected to the same driving line 112, and the driving line 112 includes at least one of a gate line and a data line. Specifically, the plurality of second pixel driving circuits 115B share a gate line with the plurality of first pixel driving circuits 115A in the same row when the display panel 100 is not bent, and the plurality of second pixel driving circuits 115B share a data line with the plurality of first pixel driving circuits 115A in the same column when the display panel 100 is not bent. In other words, the bending portion of the display panel retains the pixel driving circuits and driving lines, so that the load of the driving line of the display portion is uniform, and there is no need to add a line compensation structure, while ensuring the uniformity of the driving load, the border width is reduced. On the other hand, since the pixel driving circuit and driving line are retained in the bent portion of the display panel, the first mask plate group of the display panel can be shared with the first mask plate of a conventional rectangular display panel, thereby reducing R&D costs and manufacturing costs. As a result, the display device can not only realize a special-shaped design and reduce R&D costs and manufacturing costs, but also avoid the problem that a conventional special-shaped display device needs to add a line compensation structure.

[0069] It is worth noting that when the pixel driving circuit and driving line are retained in the curved portion, even if the light-emitting portion emits light, it can be shielded by the light-shielding structure, which will not affect the normal display of the display portion. Therefore, this embodiment does not restrict whether the curved portion emits light. On the other hand, the curved portion can be designed not to emit light through other designs, so that it does not display when in use, thereby reducing the risk of light leakage and reducing power consumption; these designs will be described in detail in other embodiments below.

[0070] In some examples, such as Figure 6 As shown, the support layer 210 includes a main body 212 and a thickened portion 214; the main body 212 is located on the side of the driving backplane 110 of the display part 100A away from the encapsulation layer 120; the thickened portion 214 is located at the corner of the main body 212 and between the bending part 100B and the display part 100A, and the thickened portion 214 is arranged in contact with at least part of the bending part 100B. Therefore, by arranging the above-mentioned thickened portion on the support layer, the display device can provide support for the bending part, and can also prevent the curvature of the bending part of the bending part from being too large to cause the risk of fracture.

[0071] In some examples, such as Figure 6 As shown, the edge of the thickened portion 214 near the bent portion 100B has a chamfer, such as a right angle chamfer or a rounded chamfer. Therefore, since the material of the support layer is relatively hard, the display device can prevent the edge of the thickened portion or the support layer from scratching or bumping the display panel.

[0072] For example, Figure 6 As shown, the edge of the thickened portion 214 close to the bending portion 100B has a right-angle chamfer. Of course, the embodiments of the present disclosure include but are not limited to this, the edge of the thickened portion close to the bending portion has a rounded chamfer.

[0073] In some examples, the thickness of the thickened portion may be greater than 1.5 times the thickness of the main body and less than 2.5 times the thickness of the main body. Of course, the disclosed embodiments include but are not limited to this; the thickness of the thickened portion may be designed according to actual conditions, as long as the thickness of the thickened portion is greater than the thickness of the main body.

[0074] In some examples, such as Figure 6 As shown, the display device 100 further includes a filling material 220, which is located between the bent portion 100B and the thickened portion 214. In this way, the filling material can further support and fix the bent portion, and can also prevent the bent portion from being deformed or broken.

[0075] In some examples, such as Figure 6 As shown, the filling material 220 includes a heat-conducting material. Thus, the filling material can also conduct the heat generated by the bending portion to the support layer for heat dissipation. At this time, the filling material is in contact with the bending portion and the thickened portion at the same time.

[0076] For example, the filling material may include foam glue and organic thermal conductive material. Of course, the embodiments of the present disclosure include but are not limited to this.

[0077] In some examples, such as Figure 6As shown, the display device 100 further includes a sealing structure 230 , which is partially located on the side of the bending portion 100B away from the support layer 210 , so as to fix and seal the bending portion 100B on the side of the support layer 210 away from the display portion 100A.

[0078] In some examples, such as Figure 6 As shown, since the bending portion 100B is bent, the encapsulation layer 120 of the bending portion 100B contacts the sealing structure 230, and the driving backplane 110 of the bending portion 100B contacts the support layer 210. The sealing structure 230 can fix and seal the bending portion 100B on the side of the support layer 210 away from the display portion 100A, and can further prevent water and oxygen from invading, thereby improving the durability of the product.

[0079] In some examples, the sealing structure 230 also includes a thermally conductive material, so as to dissipate heat from the bending portion 100B.

[0080] For example, the sealing structure includes at least one of resin, foam and organic thermal conductive material. Of course, the embodiments of the present disclosure include but are not limited to the above.

[0081] In some examples, the support layer 210 may include a heat-conducting material, such as a heat-conducting metal, so that the support layer can support the display panel while also having good heat dissipation performance.

[0082] For example, the support layer may be an aluminum plate. Of course, the embodiments of the present disclosure include but are not limited to this.

[0083] In some examples, such as Figure 6 As shown, the display device 100 further includes a light control film 240, which is located on a side of the display portion 100A away from the support layer 210. The light control film 240, which may also be called a light control film, is configured to control the direction of light emitted from the display portion 100A, thereby preventing reflection and glare, and solving the problem of reflection imaging of the display device on the front windshield of the car.

[0084] In some examples, such as Figure 6 As shown, the display device 100 further includes an anti-reflective film 250 and a cover layer 260 ; the anti-reflective film 250 is located on a side of the display portion 100A away from the support layer 210 ; the cover layer 260 is located on a side of the anti-reflective film 250 away from the support layer 210 .

[0085] In some examples, such as Figure 6 As shown, the display device 100 further includes a touch layer 270, which is located on a side of the display portion 100A away from the support layer 210. Thus, the display device can also realize a touch function.

[0086] In some examples, such as Figure 5As shown, the display device 100 further includes a COF 280 and a circuit board 290 , both of which are located on a side of the support layer 210 away from the display portion 100A.

[0087] Figure 8 This is a three-view diagram of a support layer provided by an embodiment of the present disclosure. Figure 8 As shown, the support layer 210 includes a main body 212 and a thickened portion 214; the main body 212 is located on the side of the driving backplane 110 of the display part 100A away from the encapsulation layer 120; the thickened portion 214 is located at the corner of the main body 212. Therefore, by arranging the above-mentioned thickened portion on the support layer, the display device can provide support for the bending portion, and can also prevent the curvature of the bending portion of the bending portion from being too large to cause the risk of fracture.

[0088] like Figure 8 As shown, the planar shape of the thickened portion 214 may be a triangle, thereby matching the triangular bending portion.

[0089] like Figure 8 As shown, the edge of the thickened portion 214 is a straight line. Of course, the embodiments of the present disclosure include but are not limited to this, and the edge of the thickened portion can also be an arc, in which case the plane shape of the thickened portion is a fan.

[0090] Fig.9A A partial cross-sectional schematic diagram of a support layer provided in one embodiment of the present disclosure; Fig. 9B FIG. 1 is a partial cross-sectional schematic diagram of another support layer provided in one embodiment of the present disclosure. Fig.9A As shown, the edge of the thickened portion 214 is a right-angle chamfer; Fig. 9B As shown, the edge of the thickened portion 214 is rounded and chamfered. Therefore, since the material of the support layer is relatively hard, the support layer can avoid scratching or bumping the display panel.

[0091] In some examples, the support layer 210 may include a heat-conducting material, such as a heat-conducting metal, so that the support layer can support the display panel while also having good heat dissipation performance.

[0092] For example, the support layer may be an aluminum plate. Of course, the embodiments of the present disclosure include but are not limited to this.

[0093] Fig.10 This is a schematic plan view of another display device provided by an embodiment of the present disclosure when the display panel is not bent. Fig.10 As shown, the display panel 100 includes a display portion 100A and a bending portion 100B, and the bending portion 100B is located at a corner of the display panel 100. The display panel 100 is rectangular in plan view when not bent; after the two bending portions are bent, the display panel 100 can be formed into a special-shaped display panel.

[0094] like Fig.10 As shown, the driving backplane 110 of the display portion 100A of the display panel 100 includes a plurality of first pixel driving circuits 115A, and the driving backplane 110 of the bending portion 100B of the display panel 100 includes a plurality of second pixel driving circuits 115B, and the plurality of second pixel driving circuits 115B and some of the first pixel driving circuits 115A are connected to the same driving line 112, and the driving line 112 includes at least one of a gate line and a data line. Specifically, the plurality of second pixel driving circuits 115B share a gate line with the plurality of first pixel driving circuits 115A in the same row when the display panel 100 is not bent, and the plurality of second pixel driving circuits 115B share a data line with the plurality of first pixel driving circuits 115A in the same column when the display panel 100 is not bent. In other words, the bending portion of the display panel retains the pixel driving circuits and driving lines, so that the load of the driving line of the display portion is uniform, and there is no need to add a line compensation structure, while ensuring the uniformity of the driving load, the border width is reduced. On the other hand, since the pixel driving circuit and driving line are retained in the bent portion of the display panel, the first mask plate group of the display panel can be shared with the first mask plate of a conventional rectangular display panel, thereby reducing R&D costs and manufacturing costs. As a result, the display device can not only realize a special-shaped design and reduce R&D costs and manufacturing costs, but also avoid the problem that a conventional special-shaped display device needs to add a line compensation structure.

[0095] It is worth noting that since the driving backplane 110 of the display part 100A and the bending part 100B of the display panel 100 both form a pixel driving circuit, the driving backplane 110 of the display panel can adopt a mask plate group that forms a pixel driving circuit of a rectangular display panel, thereby reducing R&D and production costs.

[0096] like Fig.10 As shown, the display unit 100A further includes a plurality of first anodes 130A; the plurality of first anodes 130A are located on a side of the plurality of first pixel driving circuits 115A close to the encapsulation layer (not shown), that is, the plurality of first anodes 130A are located above the plurality of first pixel driving circuits 115A; the plurality of first anodes 130A are arranged corresponding to the plurality of first pixel driving circuits 115A. In this arrangement, the first anodes 130A are connected to the output end of the corresponding first pixel driving circuit 115A, so that the first pixel driving circuit 115A can apply a driving current to the corresponding first anode 130A.

[0097] like Fig.10As shown, the side of the multiple second pixel driving circuits 115B of the bent portion 100B close to the encapsulation layer is not provided with an anode. In this case, although the bent portion 100B retains the second pixel driving circuit 115B and the corresponding driving line 112, since the bent portion 100B is not provided with an anode, the bent portion will not emit light, thereby avoiding defects such as light leakage. It should be noted that since the bent portion of the display panel is not provided with an anode, the mask plate used to form the anode of the display panel needs to be designed and manufactured separately.

[0098] Figure 11A-11C A schematic plan view of an evaporation mask provided in one embodiment of the present disclosure; Fig.12 A schematic plan view of another display device provided by an embodiment of the present disclosure when a display panel is not bent. Fig.12 The display panel shown in Fig.10 The display panel shown is based on Figures 11A-11C The evaporation mask shown forms an organic light-emitting layer, as follows: Fig.10 As shown on the display panel, Fig.11A The evaporation mask shown forms the first color organic light-emitting layer, and then Fig. 11B The evaporation mask shown forms the second color organic light-emitting layer, and finally Fig. 11C The evaporation mask shown forms a third color organic light-emitting layer. Fig.12 As shown, the display portion 100A of the display panel 100 also includes a first organic light-emitting layer 140A (including the above-mentioned three colors of organic light-emitting layers), which is located on the side of the multiple first anodes close to the encapsulation layer 120, that is, located above the multiple first anodes; the bending portion 100B of the display panel 100 also includes a second organic light-emitting layer 140B (including the above-mentioned three colors of organic light-emitting layers), which is located on the side of the multiple second pixel driving circuits close to the encapsulation layer 120, that is, located above the multiple second pixel driving circuits. It should be noted that the above-mentioned first organic light-emitting layer and the second organic light-emitting layer both include organic light-emitting layers of different colors, and the "first" and "second" here are only used to distinguish whether the organic light-emitting layer is located in the display portion or the bending portion; since the patterns of the organic light-emitting layer and the anode are roughly the same, Fig.10 Light colors are used to represent anodes. Fig.12 In the figure, dark color is used to represent the organic light-emitting layer; in addition, since no anode is formed in the bent portion, the second organic light-emitting layer of the bent portion is located above the plurality of second pixel driving circuits.

[0099] like Figures 11A-11C As shown, the display panel can use the vapor deposition mask set of a common rectangular display panel to manufacture the organic light-emitting layer, so that the vapor deposition mask set can be shared with the common rectangular display panel, thereby reducing the R&D cost and the manufacturing cost.

[0100] For example, the first color is red, the second color is green, and the third color is blue. Of course, the embodiments of the present disclosure include but are not limited to this.

[0101] Fig.13 This is a schematic plan view of another display device provided by an embodiment of the present disclosure when the display panel is not bent. Fig.13 As shown, the display panel 100 includes a display portion 100A and a bending portion 100B, and the bending portion 100B is located at a corner of the display panel 100. The display panel 100 is rectangular in plan view when not bent; after the two bending portions are bent, the display panel 100 can be formed into a special-shaped display panel.

[0102] like Fig.13 As shown, the driving backplane 110 of the display portion 100A of the display panel 100 includes a plurality of first pixel driving circuits 115A, and the driving backplane 110 of the bending portion 100B of the display panel 100 includes a plurality of second pixel driving circuits 115B, and the plurality of second pixel driving circuits 115B and some of the first pixel driving circuits 115A are connected to the same driving line 112, and the driving line 112 includes at least one of a gate line and a data line. Specifically, the plurality of second pixel driving circuits 115B share a gate line with the plurality of first pixel driving circuits 115A in the same row when the display panel 100 is not bent, and the plurality of second pixel driving circuits 115B share a data line with the plurality of first pixel driving circuits 115A in the same column when the display panel 100 is not bent. In other words, the bending portion of the display panel retains the pixel driving circuits and driving lines, so that the load of the driving line of the display portion is uniform, and there is no need to add a line compensation structure, while ensuring the uniformity of the driving load, the border width is reduced. On the other hand, since the pixel driving circuit and driving line are retained in the bent portion of the display panel, the first mask plate group of the display panel can be shared with the first mask plate of a conventional rectangular display panel, thereby reducing R&D costs and manufacturing costs. As a result, the display device can not only realize a special-shaped design and reduce R&D costs and manufacturing costs, but also avoid the problem that a conventional special-shaped display device needs to add a line compensation structure.

[0103] It is worth noting that since the driving backplane 110 of the display part 100A and the bending part 100B of the display panel 100 both form a pixel driving circuit, the driving backplane 110 of the display panel can adopt a mask plate group that forms a pixel driving circuit of a rectangular display panel, thereby reducing R&D and production costs.

[0104] like Fig.13As shown, the display unit 100A further includes a plurality of first anodes 130A; the plurality of first anodes 130A are located on a side of the plurality of first pixel driving circuits 115A close to the encapsulation layer (not shown), that is, the plurality of first anodes 130A are located above the plurality of first pixel driving circuits 115A; the plurality of first anodes 130A are arranged corresponding to the plurality of first pixel driving circuits 115A. In this arrangement, the first anodes 130A are connected to the output end of the corresponding first pixel driving circuit 115A, so that the first pixel driving circuit 115A can apply a driving current to the corresponding first anode 130A.

[0105] like Fig.13 As shown, the bent portion 100B also includes a plurality of second anodes 130B; the plurality of second anodes 130B are located on one side of the plurality of second pixel driving circuits 115B close to the encapsulation layer (not shown), that is, the plurality of second anodes 130B are located above the plurality of second pixel driving circuits 115B; the plurality of second anodes 130B are arranged corresponding to the plurality of second pixel driving circuits 115B. In this arrangement, the second anodes 130B are connected to the output ends of the corresponding second pixel driving circuits 115B, so that the second pixel driving circuits 115B can apply a driving current to the corresponding second anodes 130B. Thus, the mask plate used to form the anode of the display panel can be shared with the mask plate used to form the anode of the rectangular display panel, thereby reducing the R&D cost and the production cost.

Fig.15 The display panel shown in Fig.13 The display panel shown is based on Figures 14A-14C The evaporation mask shown forms an organic light-emitting layer, as follows: Fig.13 As shown on the display panel, Fig.14A The evaporation mask shown forms the first color organic light-emitting layer, and then Fig. 14B The evaporation mask shown forms the second color organic light-emitting layer, and finally Fig. 14C The evaporation mask shown forms a third color organic light-emitting layer. Fig.15 As shown, the display portion 100A of the display panel 100 also includes a first organic light-emitting layer 140A (including the above-mentioned three colors of organic light-emitting layers), which is located on the side of the multiple first anodes close to the encapsulation layer 120, that is, located above the multiple first anodes; no organic light-emitting layer is arranged between the multiple second anodes 130B of the bent portion 100B of the display panel 100 and the encapsulation layer 120, so that the bent portion does not emit light, thereby reducing the risk of light leakage.

[0107] For example, the first color is red, the second color is green, and the third color is blue. Of course, the embodiments of the present disclosure include but are not limited to this.

[0108] Fig.16 This is a schematic plan view of another display device provided by an embodiment of the present disclosure when the display panel is not bent. Fig.12 As shown, the display panel 100 includes a display portion 100A and a bending portion 100B, and the bending portion 100B is located at a corner of the display panel 100. The display panel 100 is rectangular in plan view when not bent; after the two bending portions are bent, the display panel 100 can be formed into a special-shaped display panel.

[0109] like Fig.16 As shown, the driving backplane 110 of the display portion 100A of the display panel 100 includes a plurality of first pixel driving circuits 115A, and the driving backplane 110 of the bending portion 100B of the display panel 100 includes a plurality of second pixel driving circuits 115B, and the plurality of second pixel driving circuits 115B and some of the first pixel driving circuits 115A are connected to the same driving line 112, and the driving line 112 includes at least one of a gate line and a data line. Specifically, the plurality of second pixel driving circuits 115B share a gate line with the plurality of first pixel driving circuits 115A in the same row when the display panel 100 is not bent, and the plurality of second pixel driving circuits 115B share a data line with the plurality of first pixel driving circuits 115A in the same column when the display panel 100 is not bent. In other words, the bending portion of the display panel retains the pixel driving circuits and driving lines, so that the load of the driving line of the display portion is uniform, and there is no need to add a line compensation structure, while ensuring the uniformity of the driving load, the border width is reduced. On the other hand, since the pixel driving circuit and driving line are retained in the bent portion of the display panel, the first mask plate group of the display panel can be shared with the first mask plate of a conventional rectangular display panel, thereby reducing R&D costs and manufacturing costs. As a result, the display device can not only realize a special-shaped design and reduce R&D costs and manufacturing costs, but also avoid the problem that a conventional special-shaped display device needs to add a line compensation structure.

[0110] It is worth noting that since the driving backplane 110 of the display part 100A and the bending part 100B of the display panel 100 both form a pixel driving circuit, the driving backplane 110 of the display panel can adopt a mask plate group that forms a pixel driving circuit of a rectangular display panel, thereby reducing R&D and production costs.

[0111] like Fig.16As shown, the display unit 100A further includes a plurality of first anodes 130A; the plurality of first anodes 130A are located on a side of the plurality of first pixel driving circuits 115A close to the encapsulation layer (not shown), that is, the plurality of first anodes 130A are located above the plurality of first pixel driving circuits 115A; the plurality of first anodes 130A are arranged corresponding to the plurality of first pixel driving circuits 115A. In this arrangement, the first anodes 130A are connected to the output end of the corresponding first pixel driving circuit 115A, so that the first pixel driving circuit 115A can apply a driving current to the corresponding first anode 130A.

[0112] like Fig.16 As shown, the bent portion 100B also includes a plurality of second anodes 130B; the plurality of second anodes 130B are located on one side of the plurality of second pixel driving circuits 115B close to the encapsulation layer (not shown), that is, the plurality of second anodes 130B are located above the plurality of second pixel driving circuits 115B; the plurality of second anodes 130B are arranged corresponding to the plurality of second pixel driving circuits 115B. In this arrangement, the second anodes 130B are connected to the output ends of the corresponding second pixel driving circuits 115B, so that the second pixel driving circuits 115B can apply a driving current to the corresponding second anodes 130B.

[0113] Figure 17A-Figure 17C A schematic plan view of an evaporation mask provided in one embodiment of the present disclosure; Fig.18 A schematic plan view of another display device provided by an embodiment of the present disclosure when a display panel is not bent. Fig.18 The display panel shown in Fig.16 The display panel shown is based on Figures 17A-17C The evaporation mask shown forms an organic light-emitting layer, as follows: Fig.16 As shown on the display panel, Fig.17A The evaporation mask shown forms the first color organic light-emitting layer, and then Fig. 17B The evaporation mask shown forms the second color organic light-emitting layer, and finally Fig. 17C The evaporation mask shown forms a third color organic light-emitting layer. Fig.18As shown, the display portion 100A of the display panel 100 also includes a first organic light-emitting layer 140A (including the above-mentioned three colors of organic light-emitting layers), which is located on the side of the multiple first anodes close to the encapsulation layer 120, that is, located above the multiple first anodes; the bending portion 100B of the display panel 100 also includes a second organic light-emitting layer 140B (including the above-mentioned three colors of organic light-emitting layers), which is located on the side of the multiple second pixel driving circuits close to the encapsulation layer 120, that is, located above the multiple second pixel driving circuits. It should be noted that the above-mentioned first organic light-emitting layer and the second organic light-emitting layer both include organic light-emitting layers of different colors, and the "first" and "second" here are only used to distinguish whether the organic light-emitting layer is located in the display portion or the bending portion. In addition, since no anode is formed in the bending portion, the second organic light-emitting layer of the bending portion is located above the multiple second pixel driving circuits.

[0114] like Figures 17A-17C As shown, the display panel can use the vapor deposition mask set of a common rectangular display panel to manufacture the organic light-emitting layer, so that the vapor deposition mask set can be shared with the common rectangular display panel, thereby reducing the R&D cost and the manufacturing cost.

[0115] For example, the first color is red, the second color is green, and the third color is blue. Of course, the embodiments of the present disclosure include but are not limited to this.

[0116] In some examples, the display device may be a vehicle display device such as a vehicle display, a navigation system, etc. Of course, the embodiments of the present disclosure include but are not limited to this, and the display device may also be any product or component with a display function such as a television, a digital camera, a mobile phone, a watch, a tablet computer, a laptop computer, a navigation system, etc.

[0117] At least one embodiment of the present disclosure further provides a method for manufacturing a display device. Fig.19 FIG. 1 is a flow chart of a method for manufacturing a display device provided by an embodiment of the present disclosure. Fig.19 As shown, the manufacturing method of the display device includes the following steps S101-S102.

[0118] Step S101: forming a display panel, wherein the display panel includes a driving backplane and a packaging layer.

[0119] Step S102: Arrange a display panel on the first side of the support layer, and bend the corner of the display panel toward the second side of the support layer, so that the portion of the display panel located on the first side of the support layer forms a display portion, and the portion of the display panel located on the second side of the support layer forms a bending portion.

[0120] In the manufacturing method of the display device provided in the embodiment of the present disclosure, the display device can bend a rectangular display panel into a special shape, thereby realizing a special-shaped design. Moreover, the display panel of the display device can be rectangular when not bent, so it can share at least part of the mask plate with a conventional rectangular display panel, thereby greatly reducing the R&D and manufacturing costs. It should be noted that the planar shape of the display panel when not bent is a rectangle; after the bent portion is bent, the display panel can form a special-shaped display panel.

[0121] It should be noted that the bending line between the display portion and the bending portion of the display panel can also be a curve or a fold line, so as to realize a display portion of more shapes. In other words, the boundary line between the display portion and the bending portion of the display panel can be a straight line, a curve or a fold line.

[0122] In some examples, the above-mentioned step of forming a display panel includes: using a first mask plate group to form a plurality of pixel driving circuits in a driving backplane of the display panel, the first mask plate group is used for patterning a plurality of film layers of the pixel driving circuit, the plurality of pixel driving circuits include a plurality of first pixel driving circuits located in the display portion and a plurality of second pixel driving circuits located in the bending portion, the plurality of second pixel driving circuits and part of the first pixel driving circuits are connected to the same driving line, and the driving line includes at least one of a gate line and a data line. Specifically, the plurality of second pixel driving circuits share a gate line with a plurality of first pixel driving circuits in the same row when the display panel is not bent, and the plurality of second pixel driving circuits share a data line with a plurality of first pixel driving circuits in the same column when the display panel is not bent. In other words, the bending portion of the display panel retains the pixel driving circuits and driving lines, so that the load of the driving line of the display portion is uniform, and there is no need to add a line compensation structure, while ensuring the uniformity of the driving load, the border width is reduced. On the other hand, since the bent portion of the display panel retains the pixel driving circuit and the driving line, the first mask plate group of the display panel can be shared with the first mask plate of the conventional rectangular display panel, thereby reducing the R&D cost and the manufacturing cost. As a result, the display device can not only realize the special-shaped design and reduce the R&D cost and the manufacturing cost, but also avoid the problem that the conventional special-shaped display device needs to add a line compensation structure. It should be noted that the above-mentioned first mask plate group includes at least one mask plate for patterning multiple film layers of the pixel driving circuit. These film layers may include an active layer, a gate layer, a source-drain electrode layer, and an insulating layer and a flat layer including a via structure.

[0123] In some examples, the step of forming the display panel further includes: using a second mask plate group to form a plurality of first anodes on a side of the plurality of first pixel driving circuits of the display unit close to the encapsulation layer, and the plurality of first anodes are arranged corresponding to the plurality of first pixel driving circuits. The second mask plate group includes at least one mask plate for forming the anodes. It should be noted that the second mask plate group may include only one mask plate.

[0124] In some examples, the portion of the second mask plate group corresponding to the bending portion has no pattern, so that no anode is set on the side of the multiple second pixel driving circuits of the bending portion close to the packaging layer, so that the bending portion does not emit light, thereby reducing the risk of light leakage.

[0125] In some examples, the formation of the display panel further includes: using a third mask plate group to form multiple anodes on the side of the multiple pixel driving circuits close to the encapsulation layer, the multiple anodes include multiple first anodes and multiple second anodes, the multiple first anodes are located on the side of the multiple first pixel driving circuits close to the encapsulation layer, and are arranged corresponding to the multiple first pixel driving circuits, and the multiple second anodes are located on the side of the multiple second pixel driving circuits close to the encapsulation layer, and are arranged corresponding to the multiple second pixel driving circuits. The third mask plate group includes at least one mask plate for forming anodes. It should be noted that the third mask plate group may include only one mask plate. Thus, the second mask plate group for forming the anode of the display panel can be shared with the second mask plate group for forming the anode of the rectangular display panel, thereby reducing R&D costs and production costs.

[0126] In some examples, the step of forming the display panel further includes: using a first evaporation mask plate group to form a first organic light-emitting layer on one side of the plurality of first anodes close to the encapsulation layer, and the portion of the first evaporation mask plate group corresponding to the bent portion does not have a pattern, so that the organic light-emitting layer is not provided between the plurality of second anodes of the bent portion and the encapsulation layer. Thus, since the bent portion is not provided with an organic light-emitting layer, the bent portion does not emit light, thereby reducing the risk of light leakage. It should be noted that the first evaporation mask plate may include: Figure 11A-11C The evaporation mask shown.

[0127] In some examples, the formation of the display panel further includes: using a second evaporation mask plate group to form an organic light-emitting layer on a side of the multiple anodes close to the encapsulation layer, the organic light-emitting layer includes a first organic light-emitting layer and a second organic light-emitting layer, the first organic light-emitting layer is located on a side of the multiple first anodes close to the encapsulation layer, and the second organic light-emitting layer is located on a side of the multiple second anodes close to the encapsulation layer. Therefore, the method for manufacturing the display panel can use the evaporation mask plate group of a conventional rectangular display panel to manufacture the organic light-emitting layer, so that the evaporation mask plate group can be shared with the conventional rectangular display panel, thereby reducing R&D costs and manufacturing costs. It should be noted that the second evaporation mask plate mentioned above may include: Figure 11A-11C The evaporation mask shown.
