[0003] However, multiple film layers with different functions are superimposed on the hollowed-out area of ​​the metal layer. In particular, multiple film layers are superimposed at the boundary of the organic layer in the hollowed-out area. This causes greater stress at the boundary and easily generates cracks during the high-temperature and high-humidity reliability process, which in turn causes poor reliability.

[0026] The following will be combined with the drawings in the embodiments of this specification to clearly and completely describe the technical solutions in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

[0027] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the inventive product is usually placed when in use. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0028] In the related art, different signals are transmitted through a metal layer in the lower frame of a display panel. Figure 1 FIG. 1 is a schematic diagram showing the structure of a portion of a film layer of a display panel in the related art. Figure 1As shown, in order to transmit different signals in the same film layer, a hollow region Q1 is usually provided in the metal layer M3, so that the metal layers on both sides of the hollow region Q1 transmit different signals respectively.

[0029] The metal layer M3 and the hollow area Q1 are covered with an organic layer 10, which is only located in the buffer area of ​​the display panel. Therefore, stress concentration may occur near the boundary of the organic layer 10. Figure 2 Introduce the causes and effects of stress concentration problems.

[0030] Figure 2 Shown Figure 1 The cross-sectional structure diagram of the display panel along the AA' direction is shown in FIG. Figure 2 As shown, multiple film layers are also covered on the organic layer 10, and at the boundary position of the organic layer 10, multiple film layers climb toward the organic layer 10 to form a sharp corner region T1, which increases the stress of the sharp corner region T1 at the boundary position of the organic layer 10. In the subsequent reliability process, cracks are easily generated in the sharp corner region T1. External water vapor can easily enter the interior of the display panel through the cracks, causing the display panel to have poor reliability.

[0031] In view of this, the present application provides a display panel, comprising: a bending zone and a buffer zone arranged in sequence along a first direction, the display panel comprising: a base substrate; a first inorganic layer, located on one side of the base substrate and located in the bending zone; a first organic layer, arranged on the same layer as the first inorganic layer and located in the buffer zone; wherein the orthographic projection of the first organic layer on the base substrate does not overlap with the orthographic projection of the first inorganic layer on the base substrate.

[0032] Through the above design, the number of film layers superimposed at the boundary of the first organic layer is reduced, thereby reducing the stress there. In the subsequent reliability process, the sharp corner area of ​​the organic layer boundary is not prone to cracks, so as to prevent external water vapor from entering the display panel through the cracks, thereby improving the reliability of the display panel.

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] Figure 3 FIG. 1 is a top view of a display panel provided in an embodiment of the present application. Figure 3As shown, the display panel includes a display area A1, a bending area A2 and a buffer area A3 arranged in sequence along a first direction, wherein the first direction refers to the direction from the display area A1 of the display panel to the buffer area A3. The bending area A2 and the buffer area A3 are both located at the lower frame position of the display panel. The display area A1 is an area in the display panel for realizing image display, and the display area A1 may include a plurality of light-emitting devices for displaying images, metal traces for controlling the light-emitting devices, and a metal layer for transmitting signals. The bending area A2 is used to connect the display area A1 and the buffer area A3, and can be bent toward the backlight side of the display panel so that the buffer area A3 is bent to the back of the display panel. The metal traces, metal layers and other structures in the display area A1 extend to the buffer area A3 through the bending area A2. Generally, the buffer area A3 includes a flexible material (such as the organic layer 10 mentioned above) to avoid stress concentration at the junction of the buffer area A3 and the bending area A2 due to the mechanical bending of the bending area A2, thereby improving the electronic performance and reliability of the display panel.

[0035] The portion of the buffer area A3 away from the display area A1 may also be provided with structures such as integrated circuits connected to metal wiring and metal layers.

[0036] Figure 4 for Figure 3 A schematic diagram of the structure of a portion of the film layers of the display panel in area B is provided. As described above, the display panel includes a third metal layer M3. In order to transmit different signals in the same film layer, a hollow region Q1 is provided in the third metal layer M3, so that the metal layers on both sides of the hollow region Q1 transmit different signals respectively. Exemplarily, one side of the hollow region Q1 is used to transmit an anode voltage signal (ELVDD), and correspondingly, the other side of the hollow region Q1 is used to transmit a cathode voltage signal (ELVSS).

[0037] Figure 5 for Figure 4 A schematic diagram of a cross-sectional structure of a display panel along the BB' direction is provided. Figure 5 As shown, the display panel includes a base substrate 51, a first inorganic layer 52 and a first organic layer 53. The first inorganic layer 52 and the first organic layer 53 are both located on one side of the base substrate 51, and the first inorganic layer 52 and the first organic layer 53 are arranged in the same layer.

[0038] Continue to refer Figure 3 , Figure 5, the first inorganic layer 52 is located in the display area A1 and the bending area A2. The first inorganic layer 52 may be an encapsulation layer for protecting the light-emitting device in the display area A1; in the display area A1, the first inorganic layer 52 covers the film layer where the light-emitting device is located, and extends from the display area A1 to the bending area A2 along the first direction, and is cut off before the first organic layer 53. The first organic layer 53 is located in the buffer area A3. The material of the first organic layer 53 may include organic glue, which is used to prevent the display panel from generating stress concentration due to mechanical bending of the bending area A2, and play a buffering role.

[0039] The orthographic projection of the first organic layer 53 on the base substrate 51 does not overlap with the orthographic projection of the first inorganic layer 52 on the base substrate 51. In other words, in the film layer where the first inorganic layer 52 and the first organic layer 53 are located, the first inorganic layer 52 and the first organic layer 53 do not overlap each other.

[0040] On the film layer where the first inorganic layer 52 and the first organic layer 53 are located, multiple film layers may be covered. Figure 2 It can be found from the display panel shown that, through the above settings, in the display panel of the present application, the film layer superimposed at the boundary position of the first organic layer 53 is reduced, so that the stress here is greatly reduced. During the reliability process, cracks are not easy to occur at the boundary position of the organic layer, so as to improve the reliability of the display panel.

[0041] It is understandable that the non-overlapping design of the first inorganic layer 52 and the first organic layer 53 is not only present in the hollowed-out area Q1 . In the non-hollowed-out area of ​​the lower frame area, the first inorganic layer 52 and the first organic layer 53 also do not overlap with each other.

[0042] The above settings can be achieved by replacing the mask plate of the first inorganic layer. Specifically, during the preparation of the display panel, some functional film layers in the display panel will be formed by evaporation, and a mask of the desired structure can be formed on the functional film layer through a mask plate (such as a fine mask plate), thereby controlling the precise size or pattern of the functional film layer. When preparing the first inorganic layer in the embodiment of the present application, the first inorganic layer is prepared on the substrate (or other film layers formed on the substrate) through a new mask plate, so that the first inorganic layer and the first organic layer do not overlap with each other. It can be seen that in the preparation process of the display panel, only the mask plate of the first inorganic layer needs to be replaced, which is simple to implement, easy to achieve, and can have a good effect.

[0043] In some embodiments, there is a spacing region Q2 between the orthographic projection of the first organic layer 53 on the base substrate 51 and the orthographic projection of the first inorganic layer 52 on the base substrate 51. That is, in the film layer where the first inorganic layer 52 and the first organic layer 53 are located, the first inorganic layer 52 and the first organic layer 53 do not overlap each other; further, there is a certain spacing distance between the boundaries of the first inorganic layer 52 and the first organic layer 53, and the spacing distance is projected on the substrate to form the spacing region Q2. The spacing distance can be flexibly designed according to the actual size of the display panel.

[0044] In this embodiment, by increasing the distance between the boundary of the first inorganic layer 52 and the boundary of the first organic layer 53 , the probability of stress increase and crack generation at the boundary of the first organic layer 53 can be further reduced.

[0045] Next, other film layers in the display panel are introduced.

[0046] Figure 6 FIG. 2 is a schematic diagram of a cross-sectional structure of a display panel provided by another embodiment of the present application. Figure 6 As shown, the display panel also includes a first metal layer M1 and a second metal layer M2. The first metal layer M1 and the second metal layer M2 are both located between the first organic layer 53 (and the first inorganic layer 52) and the base substrate 51, and the first metal layer M1 is located on the side of the second metal layer M2 close to the base substrate 51.

[0047] In some embodiments, in addition to the film structure described above, the display panel also includes a second inorganic layer 54 and a third inorganic layer 55. The second inorganic layer 54 is located on the side of the first inorganic layer 52 and the first organic layer 53 close to the base substrate 51. The second inorganic layer 54 is also located on the side of the second metal layer M2 away from the base substrate 51. The second inorganic layer 54 is an insulating layer that can prevent external water vapor from invading the interior of the display panel and causing problems such as metal corrosion; at the same time, the second inorganic layer 54 can also isolate different conductive layers to prevent electrical short circuits and crosstalk. Inorganic materials usually have excellent thermal stability and chemical stability and are suitable for use in harsh environments.

[0048] The third inorganic layer 55 is located on a side of the first inorganic layer 52 and the first organic layer 53 away from the substrate 51. The third inorganic layer 55 is an encapsulation layer to further protect the film structure below the third inorganic layer 55 from environmental factors such as moisture, oxygen, dust and chemicals.

[0049] In some embodiments, there is a spacing region between the orthographic projection of the first organic layer 53 on the base substrate 51 and the orthographic projection of the first inorganic layer 52 on the base substrate 51, and the spacing region exposes the second inorganic layer 54 below. In this case, the third inorganic layer 55 contacts the second inorganic layer 54 in the spacing region; that is, the third inorganic layer 55 covers the first inorganic layer 52, the second inorganic layer 54 in the spacing region, and the first organic layer 53 at the same time, and the third inorganic layer can prevent external water vapor from invading the film layer below, thereby improving the reliability of the display panel.

[0050] Continue to refer Figure 4 , Figure 6 , the third metal layer M3 of the display panel is located on the side of the second metal layer M2 away from the substrate; and is also located on the side of the second inorganic layer close to the substrate. The third metal layer M3 includes a hollow area Q1, the hollow area Q1 is located outside the barrier dam of the display panel, and the orthographic projection of the hollow area Q1 on the substrate has an overlapping area with the orthographic projection of the first organic layer on the substrate. Based on the setting of the hollow area Q1, the third metal layer M3 can transmit different signals on the left and right sides of the hollow area Q1.

[0051] The film structure of the first metal layer and the second metal layer is further described below.

[0052] Figure 7 FIG. 2 is a schematic diagram of a cross-sectional structure of a display panel provided in yet another embodiment of the present application. Figure 7 As shown, the first metal layer includes a plurality of first metal lines 56, and the second metal layer includes a plurality of second metal lines 57. The first metal lines 56 and the second metal lines 57 are alternately arranged in a second direction, and the second direction intersects the first direction. The first metal lines 56 and the second metal lines 57 may be data lines. The data lines are used to transmit data signals to the light-emitting devices in the display area, and the data signals can control the brightness of the light-emitting devices, thereby controlling the content of the image displayed in the display area.

[0053] The display panel also includes a fourth inorganic layer, which is located on the side of the base substrate close to the first metal layer, and the first metal wire 56 in the first metal layer is arranged inside the fourth inorganic layer. The second metal wire 57 in the second metal layer is arranged on the side of the fourth inorganic layer away from the base substrate; the second metal wire 57 is also arranged on the side of the base substrate away from the base substrate, and the side of the fourth inorganic layer away from the base substrate, and the fifth inorganic layer also covers the second metal wire 57. Through the above arrangement, the first metal wire 56 is wrapped by the fourth inorganic layer, and the second metal wire 57 is wrapped by the fourth inorganic layer and the fifth inorganic layer; the fourth inorganic layer and the fifth inorganic layer are both insulating layers to protect the first metal wire 56 and the second metal wire 57.

[0054] In the related art, continue to refer to Figure 2 , below the organic layer 10, since the first metal wires and the second metal wires are arranged alternately and at intervals, the film layer covered thereon presents a sharp-angled area T2. The stress in the sharp-angled area T2 is relatively large, so cracks are easily generated during the reliability process. Combined with the problem that the sharp-angled area T1 is prone to cracks, external water vapor can enter the display panel from the outside along the cracks formed in the sharp-angled areas T1 and T2, and contact the first metal wires and the second metal wires, causing corrosion of the metal wires, thereby reducing the reliability of the display panel.

[0055] As mentioned above, data lines play an important role in the display process. If the data lines are corroded, horizontal or vertical bright lines, dark lines or color bands may appear in the displayed image, affecting the continuity of the image and thus the display quality. Furthermore, the corrosion of the data lines may cause poor connection or even breakage of the data lines, thereby interrupting signal transmission and causing display abnormalities. In addition, the data lines are located deep in the display panel, and maintenance may be very difficult, affecting the service life of the display panel.

[0056] To reduce the risk of metal line corrosion, in the embodiment of the present application, at least part of the first metal line and at least part of the second metal line are located in the buffer zone. In the buffer zone, the orthographic projections of adjacent first metal lines and second metal lines on the substrate overlap.

[0057] Figure 8 Shown Figure 7 The provided display panel is a partial enlarged view of area C. Figure 7 , Figure 8 As shown, the orthographic projection of the first metal line 56 on the substrate partially overlaps with the orthographic projection of the second metal line 57 on the substrate, so that during the preparation of the display panel, the slope of the groove deposited above the first metal line 56 and the second metal line 57 is reduced. Therefore, the film layer (such as the second inorganic layer) deposited on the first metal line 56 and the second metal line 57 can present a relatively gentle morphology at the first metal line 56, the second metal line 57 and the overlapping position of the two.

[0058] Continue to refer Figure 6 , Figure 7 The boundary of the first organic layer 53 close to the first inorganic layer 52 is located on the smooth film surface formed by the overlap of the first metal wire 56 and the second metal wire 57, so as to reduce the stress concentration at the boundary position of the first organic layer 53, thereby avoiding the generation of cracks at the boundary position of the first organic layer 53 during the high temperature and high humidity reliability process, thereby improving the reliability of the display panel.

[0059] Through the above arrangement, it is possible to avoid the film layer deposited above the first metal wire and the second metal wire from forming a sharp-angled morphology, so as to solve the problem of cracks in the upper film layer due to excessive stress during the reliability process.

[0060] The above setting can also be achieved by changing the mask of the second metal line. Specifically, the pattern on the new mask defines the path of the second metal line, and in the process of preparing the second metal line, the second metal line is formed on the fifth inorganic layer through the new mask, so that the second metal line is located at an appropriate position.

[0061] In some embodiments, the orthographic projection of the first organic layer on the base substrate has an overlapping area with the orthographic projections of the adjacent first metal traces and second metal traces of the buffer zone on the base substrate. Figure 6 , Figure 7 In order to ensure that the film layer below the boundary position of the first organic layer does not produce cracks, the orthographic projection of the boundary of the first organic layer 53 on the base substrate 51 can be set to be within the range of the orthographic projections of the adjacent first metal traces 56 and the second metal traces 57 on the base substrate 51, and the orthographic projection of part of the first organic layer 53 on the base substrate 51 overlaps with the orthographic projections of the adjacent first metal traces 56 and the second metal traces 57 on the base substrate 51.

[0062] Since the film layer below the boundary of the first organic layer presents a relatively gentle morphology, cracks near the boundary of the first organic layer can be further avoided. Figure 2 The sharp corner areas T1 and T2 in the display panel are not prone to cracks, which solves the problem of external water vapor entering the display panel along the cracks during the reliability process, causing corrosion of the metal wiring.

[0063] In some embodiments, in adjacent first metal routings and second metal routings in the buffer zone, the orthographic projection of the side of the first metal routing close to the second metal routing on the substrate substrate at least partially overlaps with the orthographic projection of the side of the second metal routing close to the first metal routing on the substrate substrate.

[0064] Specifically, continue to refer to Figure 7Since the metal wiring has a certain thickness, affected by its preparation process, the cross-sectional shape of the metal wiring generally includes a trapezoid or a nearly trapezoid. Therefore, for the adjacent first metal wiring 56 and the second metal wiring 57, the side 561 on the right side of the first metal wiring 56 and the side 571 on the left side of the second metal wiring 57 are close to each other, and the orthographic projection of the side 561 of the first metal wiring 56 on the substrate substrate and the orthographic projection of the side 571 of the second metal wiring 57 on the substrate substrate at least partially overlap. In this case, it can be ensured that the overlapping area of ​​the orthographic projections of the first metal wiring 56 and the second metal wiring 57 on the substrate substrate is small, so that the flat area of ​​the film layer deposited above the adjacent first metal wiring 56 and the second metal wiring 57 presents a longer length, which facilitates the formation of the first organic layer on the flat area of ​​the film layer. In addition, it is also convenient to set the boundary of the first inorganic layer in the flat area of ​​the film layer, and ensure that the boundaries of the first organic layer and the first inorganic layer do not overlap each other, further improving the reliability of the display panel.

[0065] It is understandable that only two layers of metal wiring are provided in the display panel of the above embodiment. In the application process, the display panel may include three or even multiple layers of metal wiring. In this case, the multiple layers of metal wiring in the buffer zone can be arranged in parallel, and the orthographic projections of adjacent metal wirings on the substrate are partially overlapped. The specific implementation can refer to the implementation of the above embodiment, so that the film layer above the metal wiring presents a relatively flat morphology.

[0066] Fig. 9 FIG. 2 is a schematic diagram of a cross-sectional structure of a display panel provided by another embodiment of the present application. Fig. 9 As shown, in addition to the film layer structure described in the above embodiment, the display panel also includes a second organic layer 58. The second organic layer 58 is located on the side of the third inorganic layer 55 away from the base substrate 51. The second organic layer 58 is an insulating layer, which can isolate different film layers to prevent electrical short circuits and crosstalk. At the same time, the second organic layer 58 can also provide physical protection for the underlying film layer to prevent mechanical damage and environmental factors; and prevent water vapor intrusion. In addition, the organic encapsulation layer has a large thickness and has a flattening function, so that other functional structures can be arranged on the second organic layer 58.

[0067] It can be understood that the film layer structure of the display panel in the above embodiment is only illustrative, and those skilled in the art can set or adjust the film layer structure in the display panel according to actual needs.

[0068] Based on the same inventive concept, the present application also provides an electronic device, including the display panel provided in the above embodiments of the present application. In the embodiments of the present application, the electronic device may include a mobile phone, a tablet computer, a smart wearable device, a television, a laptop computer, a display, and other devices with display functions. The present application does not specifically limit the specific form of the electronic device.

[0069] Since the principle of solving the problem in the electronic device embodiment is similar to that in the above-mentioned display panel embodiment, the implementation of the electronic device embodiment may refer to the implementation of the above-mentioned display panel embodiment, and the repeated parts will not be repeated.

[0070] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
