Mode for Carrying Out the Invention
[0019] Hereinafter, the features and exemplary embodiments of each aspect of the present application will be described in detail. In the following detailed description, many specific details are set forth in order to provide a comprehensive understanding of the present application. However, as will be apparent to those skilled in the art, the present application may be practiced without some of these specific details. The following description of the embodiments is provided only to illustrate examples of the present application and to better understand the present application.
[0020] In this specification, relational terms such as "First" and "Second," etc., are merely used to distinguish one entity or operation from another and do not necessarily require or imply that such an actual relationship or order exists between these entities or operations. Furthermore, the terms "includes," "has," "equips," or any other variation thereof are intended to cover non-exclusive inclusion, and a process, method, article, or device that includes a set of elements includes not only those elements but also other elements not explicitly listed, or further elements specific to such a process, method, article, or device. Unless otherwise specified, an element limited by the phrase "...includes" does not preclude the presence of other identical elements in a process, method, article, or equipment that includes the element.
[0021] As the inventors' research has shown, the reason why display devices are prone to signal interference problems in the frame is that, in conventional display panels, the touch wiring of the touch layer is susceptible to interference between the non-display area and the signal lines in the substrate because there is no metal layer acting as a shielding barrier between the non-display area and the signal lines in the substrate. Based on research into the above problem, the inventors provide a display panel, a method for manufacturing the same, and a display device for reducing the signal interference problem in the non-display area.
[0022] To better understand this application, the display panel, its manufacturing method, and display device according to the embodiment of this application will be described in detail below with reference to Figures 1 to 10.
[0023] Referring to Figures 1 and 2, an embodiment of the present application provides a display panel 1 including a display area AA and a non-display area NA that surrounds at least a portion of the display area AA. The display panel 1 includes a substrate 11, a light-emitting unit 13, a shielding structure, and a conductive layer 15.
[0024] The light-emitting unit 13 is formed on one side of the substrate 11 and located within the display area AA, while the conductive layer 15 is formed on the side of the light-emitting unit 13 away from the substrate 11. The shield structure is provided between the conductive layer 15 and the substrate 11 and at least a portion of it is located within the non-display area NA, and the orthographic projection of the shield structure on the substrate 11 overlaps with the orthographic projection of the conductive layer 15 on the substrate 11.
[0025] The display panel 1 according to the present invention includes a display area AA and a non-display area NA. The display area AA is an area for realizing the display function of the display panel 1, and the non-display area NA is provided surrounding the periphery of the display area AA. The non-display area NA is used for arranging structures such as a drive chip and a drive circuit.
[0026] The display panel 1 includes a substrate 11, and a film layer or device structure such as a light-emitting unit 13, a shielding structure, and a conductive layer 15 is formed on the same side of the substrate 11. Here, the substrate 11 may include a plurality of film layer structures stacked within it, and the embodiments of this application are not limited to the specific configuration of the film layers within the substrate 11. For example, the substrate 11 may contain a plurality of conductor layers and semiconductor layers, and insulating layers located between adjacent conductor layers and semiconductor layers, with conductor structures provided within the conductor layers and active structures provided within the semiconductor layers. Furthermore, the substrate may include a circuit structure, and the circuit structure may include a pixel circuit in the display area, a scanning circuit in the non-display area, or other types of circuits, and the embodiments of this application are not limited to these.
[0027] The substrate 11 may also contain thin-film transistors for forming a pixel circuit that drives the light emission of the light-emitting unit 13, and the thin-film transistors include a conductive structure located in a part of the conductive layer and an active structure located in the semiconductor layer.
[0028] In related technologies, some structures in the conductive layer 15 and some conductive structures in the substrate 11, such as signal lines 111, are arranged opposite each other in the non-display area NA, making them prone to interference. In view of this, the embodiment of the present invention adds a shielding structure within the display panel 1, which is provided between the conductive layer 15 and the substrate 11, and at least a portion of it is located within the non-display area NA. The presence of the shielding structure provides a signal shielding effect between some structures in the conductive layer 15 located within the non-display area NA and the signal lines 111 in the substrate 11, thereby reducing the risk of signal interference. This protects the conductive structures in the substrate 11 and the conductive layer 15, improving the yield and reliability of the display panel 1.
[0029] The embodiments of this application do not limit the specific type of conductor layer 15. Selectively, the structure within the conductor layer 15 may be used to transmit touch signals, or the structure within the conductor layer 15 may be used to transmit other signals, provided that the conductor layer 15 is located on the side of the light-emitting unit 13 away from the substrate 11.
[0030] In some embodiments, the shield structure includes an isolation structure 12 formed on one side of the substrate, the isolation structure 12 includes a first portion 121 located within the display area AA and a second portion 122 located within the non-display area NA, the first portion 121 surrounding and forming a first opening 1211, and the light-emitting unit 13 is located within the first opening 1211. The orthographic projection of the second portion 122 on the substrate 11 is provided to overlap with the orthographic projection of the conductive layer 15 on the substrate 11.
[0031] The isolation structure 12 is formed on one side of the substrate 11 and includes a first portion 121 located in the display area AA and a second portion 122 located in the non-display area NA. The first portion 121 surrounds and forms a first opening 1211, and the second portion 122 surrounds and forms a second opening 1221. The first opening 1211 is for housing the light-emitting unit 13, and the first opening 1211 prevents the isolation structure 12 from blocking the light emission of the light-emitting unit 13.
[0032] In the embodiment of the present invention, the second portion 122 of the isolation structure 12 is located within the non-display region NA, and the orthographic projection of the second portion 122 on the substrate 11 is provided to overlap with the orthographic projection of the conductive layer 15 on the substrate 11. In such a design, the presence of the second portion 122 enables mutual shielding between the portion of the conductive layer 15 located within the non-display region NA and the signal line 111 located within the non-display region NA on the substrate 11, thereby reducing mutual interference between the signal in the portion of the conductive layer 15 located within the non-display region NA and the signal in the signal line 111, and improving the reliability of the display panel 1.
[0033] Furthermore, selectively, in the non-display region NA, the orthographic projection of the second portion 122 on the substrate 11 completely covers the orthographic projection of the conductive layer 15 on the substrate 11.
[0034] In the embodiment of the present invention, the dimensions and shape of the second portion 122 depend on the structure of the portion located in the non-display area NA of the conductive layer 15. By adjusting the dimensions and shape of the second portion 122, the orthographic projection on the substrate 11 completely covers the orthographic projection of the conductive layer 15 on the substrate 11, thereby improving the shielding effect of the second portion 122 between the portion of the conductive layer 15 located in the non-display area NA and the signal lines 111 located within the non-display area NA of the substrate 11.
[0035] Selectively, the first and second parts of the isolation structure do not have to be exactly the same; at least some of the film layer materials of the first and second parts are the same, and they can be manufactured in the same layer. For example, the isolation structure includes a first layer and a second layer that are stacked on top of each other, and only the first or second layer of the first and second parts may be the same. In this way, the manufacturing process can be simplified, and the shield structure can be manufactured using conventional processes.
[0036] Of course, the first and second parts may be provided as completely identical film layer structures, and this application does not specifically limit this.
[0037] The second part may have a single-sided structure in the non-display area and may be provided surrounding the display area. In this way, a shielding structure is formed around the display area, thereby avoiding mutual interference between the conductive layer and the circuit structure.
[0038] The second part being a single-plane structure means that at least some of the film layer structure does not have a second opening in the non-visible region.
[0039] In some embodiments, the light-emitting unit 13 may include a first electrode 131, a light-emitting functional layer 132, and a second electrode 133, which are stacked along the direction away from the substrate 11, and the shield structure includes a shield layer 14, the shield layer 14 being manufactured as a single layer together with the second electrode 133.
[0040] The shield layer 14 and the second electrode 133 are manufactured in the same layer; that is, the shield layer 14 and the second electrode 133 are located in the same film layer, and furthermore, they are manufactured together in the same process, so that the same conductive material can be contained inside both.
[0041] In other embodiments, the shield layer 14 is manufactured in the same layer as the first electrode 131, that is, the shield layer 14 and the first electrode 131 are located in the same film layer, and furthermore, they can be manufactured together in the same process and contain the same conductive material inside.
[0042] The second electrode 133 is located within the display area AA and, together with the first electrode 131, drives the light-emitting functional layer 132 to realize the light-emitting function and meet the display requirements of the display panel 1. The shield layer 14 is manufactured in the same layer as the second electrode 133 and is provided within the non-display area NA. The presence of the shield layer 14 enables mutual shielding between the portion of the conductive layer 15 located within the non-display area NA and the signal lines 111 located within the non-display area NA of the substrate 11. This reduces mutual interference between the signals in the portion of the conductive layer 15 located within the non-display area NA and the signals in some of the conductive structures within the substrate 11, thereby improving the reliability of the display panel 1.
[0043] In several selectable embodiments, the orthographic projection of the shielding layer 14 on the substrate 11 overlaps with the orthographic projection of the conductive layer 15 on the substrate 11. More selectively, in the non-display region NA, the orthographic projection of the shielding layer 14 on the substrate 11 completely covers the orthographic projection of the conductive layer 15 on the substrate 11.
[0044] In the embodiment of the present invention, the dimensions and shape of the shield layer 14 depend on the structure of the portion of the conductive layer 15 located in the non-display region NA. By adjusting the dimensions and shape of the shield layer 14, the orthographic projection on the substrate 11 completely covers the orthographic projection of the conductive layer 15 on the substrate 11. This improves the shielding effect of the shield layer 14 between the portion of the conductive layer 15 located in the non-display region NA and the signal lines 111 located within the non-display region NA of the substrate 11.
[0045] In some embodiments, the shield structure includes an isolation structure 12 and a shield layer 14 formed on one side of the substrate 11, the isolation structure 12 includes a first portion 121 located in the display area AA and a second portion 122 located in the non-display area NA, the first portion 121 surrounding and forming a first opening 1211, and the second portion 122 surrounding and forming a second opening 1221. The light-emitting unit 13 is located in the first opening 1211, and the shield layer 14 includes a first sub-portion 141 located within the second opening 1221, the first sub-portion 141 is second part 122 It is installed by being electrically connected to it.
[0046] The isolation structure 12 includes a first portion 121 located in the display area AA and a second portion 122 located in the non-display area NA, with the first portion 121 and the second portion 122 enclosing each other to form a first opening 1211 and a second opening 1221. At least one light-emitting unit 13 may be formed within each first opening 1211, and the second electrode 133 of the light-emitting unit 13 can be electrically connected to the first portion 121 to achieve synchronous power supply to the second electrode 133.
[0047] At least a portion of the shield layer 14 is formed in the second opening 1221 and is electrically connected to the second portion 122. This allows the second portion 122 in the non-display area NA and the shield layer 14 to form a continuous film layer, thereby achieving mutual shielding between the portion of the conductive layer 15 located in the non-display area NA and the signal lines 111 in the non-display area NA of the substrate 11. This reduces mutual interference between the signals in the portion of the conductive layer 15 located in the non-display area NA and the signals in the signal lines 111 in the substrate 11, thereby improving the yield of the display panel 1.
[0048] At the same time, the second portion 122 within the non-display area NA surrounds the second opening 1221, and at least a portion of the shield layer 14 is located in the second opening 1221. This allows the shield layer 14 and the isolation structure 12 to be alternately arranged along a direction parallel to the substrate 11, reducing the problem of large areas of metal being prone to peeling after contact with the lower film layer. It also prevents static electricity, protecting the signal lines 111 within the substrate 11, and reducing the risk of the signal lines 111 within the substrate 11 becoming blackened, damaged, or broken due to static electricity, thereby reducing the risk of circuit breaks and short circuits.
[0049] Furthermore, in the isolation structure 12, the first part 121 and the second part 122 may be connected to achieve synchronous power supply between the first part 121 and the second part 122. By supplying DC power within the isolation structure 12, synchronous power supply between the second part 122 and the shield layer 14, and synchronous power supply between the first part 121 and the second electrode 133 can be achieved, and by supplying DC power within the second part 122 and the shield layer 14, a good shielding effect can be achieved.
[0050] Specifically, the first part 121 and the second part 122 can be patterned simultaneously to form a mesh structure, and the first part 121 and the second part 122 may be an integrated structure.
[0051] Specifically, the orthographic projection of the first sub-part 141 in the second opening 1221 can cover the second opening 1221. As a result, the area between the second opening 1221 is shielded by the second part 122, and the area within the second opening 1221 is shielded by the first sub-part 141, achieving a sealed shielding effect.
[0052] Furthermore, in some embodiments, the shield layer 14 further includes a second sub-part 142 located on the side of the second part 122 away from the substrate 11, in addition to the first sub-part 141. That is, during the manufacturing process of the shield layer 14, some material falls into the second opening 1221 to form the first sub-part 141, and some material falls on the side of the second part 122 away from the substrate 11 to form the second sub-part 142.
[0053] In one feasible embodiment, as shown in Figure 4, the light-emitting unit 13 includes a first electrode 131, a light-emitting functional layer 132, and a second electrode 133, which are stacked along the direction away from the substrate 11, and the shielding layer 14 is manufactured as a single layer with the second electrode 133.
[0054] In the above embodiment, the shield layer 14 can be manufactured at the same time as the second electrode 133. That is, the second electrode 133 and the shield layer 14 are manufactured and formed using the same material and process, thereby simplifying the manufacturing process of the display panel 1 and saving manufacturing costs without increasing the number of manufacturing steps for the display panel 1. During the manufacturing process, the shield layer 14 can be formed into a first sub-part 141 located within the second opening 1221 and a second sub-part 142 located on the side of the second support 1322 away from the second part 122. The first sub-part 141 is electrically connected to the second part 122, and the first sub-part 141 covers the second opening 1221, thereby forming a sealed layer with the second part 122 and the first sub-part 141, improving the shielding effect.
[0055] In one viable embodiment, as shown in Figure 2, the light-emitting material layer 1320 is further included, the light-emitting material layer 1320 is provided in the same layer as at least a portion of the light-emitting functional layer 132, and the light-emitting material layer 1320 includes a first support 1321 located within the second opening 1221 and a second support 1322 located on the side of the second portion 122 away from the substrate 11.
[0056] In the above embodiment, the light-emitting material layer 1320 is provided in the same layer as the light-emitting functional layer 132 and is manufactured using the same manufacturing process. The light-emitting material layer 1320 includes a first support 1321 located within the second opening 1221 and a second support 1322 located on the side of the second portion 122 away from the substrate 11.
[0057] In one viable embodiment, as shown in Figures 2 and 4, the non-display area NA further includes a leveling area NA1 located on the side of the second portion 122 away from the display area AA, and the display panel 1 further includes a sealing layer 16, the sealing layer 16 located on the side of the shielding layer 14 and the light-emitting unit 13 away from the substrate 11, and located between the substrate 11 and the conductive layer 15. Along the direction perpendicular to the plane on which the substrate 11 is located, the thickness of the portion of the sealing layer 16 located within the leveling area NA1 is less than the thickness of the portion located within the display area AA, and less than the thickness of the portion located between the leveling area NA1 and the display area AA.
[0058] In the above embodiment, the display panel 1 further includes a sealing layer 16, which is located between the light-emitting unit 13 and the conductive layer 15 and between the shielding layer 14 and the conductive layer 15. The sealing layer 16 may also include a first sealing layer 161, a second sealing layer 162, and a third sealing layer 163, which are laminated along the direction away from the substrate 11. The materials of the first sealing layer 161 and the third sealing layer 163 may be inorganic materials, which have a strong ability to block moisture and oxygen. The material of the second sealing layer 162 may be an organic material, which has strong fluidity.
[0059] As shown in Figure 4, the direction away from the display area AA of the non-display area NA further includes a leveling area NA1 for achieving leveling of the second sealing layer 162. The non-display area NA may further include a barrier area NA2 located on the side of the leveling area NA1 away from the display area AA, and the barrier area NA2 includes a dam 18 for achieving a barrier against the second sealing layer 162.
[0060] Specifically, the leveling region NA1 has a dimension D greater than 50 μm in the direction from the display region AA to the non-display region NA, which provides sufficient space for leveling the second sealing layer 162 and improves the flatness of the side of the second sealing layer 162 away from the substrate 11.
[0061] In the above embodiment, the thickness of the sealing layer 16 can be gradually reduced from the display area AA towards the leveling area NA1. Here, the thickness is perpendicular to the plane on which the substrate 11 is located, that is, it refers to the dimension along the thickness direction of the substrate 11. The portion of the sealing layer 16 located above the second portion 122 also gradually thins from the display area AA towards the leveling area NA1, and the sealing layer 16 located above the second portion 122 that is located away from the display area AA becomes thinner more noticeably. At this time, by forming the second support portion 1322 of the light-emitting material layer 1320 and the second sub-portion 142 of the shield layer 14 on the side of the second portion 122 away from the substrate 11, the first sealing layer 161 can be continuously provided on the side of the second portion 122 away from the substrate, and the sealing layer 16 can contact the side of the isolation structure 12 away from the second opening 1221. This ensures that the surface of the second portion 122 away from the substrate 11 is covered and sealed, reducing the probability of exposure after a sealing failure of the second portion 122, preventing the problem of shielding failure in the second portion 122, and improving the reliability of the shielding effect of the second portion 122.
[0062] In one feasible embodiment, the sealing layer 16 contacts the side surface of the isolation structure 12 facing the second opening 1221, thereby covering the first sub-part 141 and overlapping and connecting with the isolation structure 12 to form a good sealing effect.
[0063] In one viable embodiment, the shield layer 14 includes a first sub-part 141 located within the second opening 1221 and a second sub-part 142 located on the side of the second part 122 away from the substrate 11, and the sealing layer 16 is in contact with the side of the second sub-part 142 away from the substrate 11, thereby preventing the sealing layer 16 from floating and improving the probability of moisture and oxygen entering between the sealing layer 16 and the underlying film layer from a floating position, thereby improving the sealing yield, further enhancing the shielding effect, and reducing the probability of shielding failure after the first sub-part 141 is eroded by moisture and oxygen.
[0064] In one viable embodiment, the conductive layer 15 includes a touch layer, the touch layer includes touch wiring 151 located in a non-display area NA, and the orthographic projection of the touch wiring 151 on the substrate 11 lies within the orthographic projection of the shielding layer 14 on the substrate 11, and / or within the orthographic projection of the isolation structure 12 on the substrate 11.
[0065] In the above embodiment, the conductive layer 15 may include a touch layer or other film layers to realize a touch function, and the present application is not particularly limited thereto. The touch layer includes touch wiring 151 located in the non-display area NA, the shielding layer 14 contacts the second portion 122 to form a continuous shielding surface, and the orthographic projection of the touch wiring 151 on the substrate 11 is located within the orthographic projection of the shielding layer 14 on the substrate 11, and / or within the orthographic projection of the isolation structure 12 on the substrate 11, thereby enabling shielding between the touch wiring 151 and the conductive film layer in the substrate 11.
[0066] Specifically, as shown in Figure 3, the touch layer further includes a touch electrode 152 and connecting lines 153 located in the display area AA, the touch electrode 152 may include a first touch electrode 1521 and a second touch electrode 1522, the connecting lines 153 may include a first connecting line 1531 and a second connecting line 1532, and the touch layer may include a first conductive layer and a second conductive layer stacked along the direction away from the substrate 11, the first conductive layer and the second conductive layer being insulated from each other. The first conductive layer includes a first connecting line 1531, and the second conductive layer includes touch electrodes 152 and a second connecting line 1532. The first touch electrodes 1521 are arranged in a matrix, and at least partially adjacent first touch electrodes 1521 along the column direction are electrically connected by the first connecting line 1531. The second touch electrodes 1522 are arranged in a matrix, and at least partially adjacent second touch electrodes 1522 along the row direction are electrically connected by the second connecting line 1532. The connecting line 153 and / or touch electrodes 152 are directly connected to the touch wiring 151.
[0067] In one viable embodiment, the substrate 11 includes a metal layer, the metal layer includes metal wiring located in a non-display area NA, the metal wiring includes signal lines 111, and is different from the signals in the touch wiring 151. The orthographic projection of the touch wiring 151 on the metal layer overlaps with the metal wiring at least partially. The overlapping areas are more prone to interference, and the shielding layer 14 and isolation structure 12 provide shielding to the signals in the touch wiring 151 and metal wiring, thereby reducing interference and improving the performance of the display panel 1.
[0068] In one viable embodiment, as shown in Figure 5, the non-display area NA includes at least one second opening 1221, the second opening 1221 surrounding the display area AA.
[0069] Specifically, the non-display area NA includes only one second opening 1221, which surrounds the display area AA, or the non-display area NA includes multiple second openings 1221, each of which surrounds the display area AA, and the multiple second openings 1221 are arranged in a sequentially nested manner (not shown).
[0070] By providing the second opening 1221 so as to surround the display area AA, the area of the second opening 1221 can be increased, ensuring the flatness of the film layer below the touch wiring 151 and reducing the risk of the touch wiring 151 breaking.
[0071] In one viable embodiment, as shown in Figures 5 and 6, the touch wiring 151 includes a wiring section 1510 that extends to enclose a portion of the display area AA, and the orthographic projection of the wiring section 1510 on the substrate 11 lies within the orthographic projection of the second aperture 1221 on the substrate 11.
[0072] Specifically, the edges of the display area AA may be rectangular, and the wiring section 1510 may include a portion extending along the row direction and a portion extending along the column direction in the arrangement direction of the touch electrodes 152, with the row and column directions being parallel to the two sides of the rectangle, respectively.
[0073] The wiring section 1510 extends to enclose a portion of the display area AA, that is, the extension direction of the wiring section 1510 and the second aperture 1221 is the same. As a result, the orthographic projection of the wiring section 1510 on the substrate 11 lies within the orthographic projection of the second aperture 1221 on the substrate 11, and the first sub-part 141 of the shielding layer 14 is provided within the second aperture 1221, allowing the first sub-part 141 to shield the wiring section 1510 and the signal lines 111 within the substrate 11. At the same time, since the wiring section 1510 does not pass through the edge of the second aperture 1221, the flatness of the film layer beneath the wiring section 1510 is improved, reducing the risk of short circuits and disconnections of the touch wiring 151 and improving the reliability and stability of the touch wiring 151. Simultaneously, the film layer beneath the wiring section 1510 is made the same, improving the differences between different wiring sections 1510 and contributing to improved transmission quality of touch signals.
[0074] Specifically, the orthographic projection of the wiring section 1510 on the substrate 11 lies within the orthographic projection of the shielding layer 14 on the substrate 11. More specifically, the orthographic projection of the wiring section 1510 on the substrate 11 lies within the orthographic projection of the first sub-part 141 on the substrate 11. As a result, the wiring section 1510 does not pass over the edge of the isolation structure 12, but only over the first sub-part 141, thereby improving the flatness of the film layer below the wiring section 1510, and enabling the first sub-part 141 to achieve a good shielding effect.
[0075] In one viable embodiment, as shown in Figure 2, the touch wiring 151 includes a wiring section 1510 that extends to enclose a portion of the display area AA, wherein the orthographic projection of a portion of the wiring section 1510 on the substrate 11 lies within the orthographic projection of the second opening 1221 on the substrate 11, and the orthographic projection of a portion of the wiring section 1510 on the substrate 11 lies within the orthographic projection of the second portion 122 on the substrate 11, and the edges of the orthographic projection of the second portion 122 on the substrate 11 do not overlap with the orthographic projection of the wiring section 1510 on the substrate 11.
[0076] In the above embodiment, the orthographic projection of some wiring sections 1510 on the substrate 11 lies within the orthographic projection of the second opening 1221 on the substrate 11, and the orthographic projection of some wiring sections 1510 on the substrate 11 lies within the orthographic projection of the second portion 122 on the substrate 11. That is, some wiring sections 1510 are located above the second opening 1221, and some wiring sections 1510 are located above the second portion 122, and in either case, the flatness of the film layer below the wiring section 1510 can be ensured. It is sufficient that the wiring section 1510 is not located above the edge of the second portion 122, i.e., above the edge of the second opening 1221. The edge of the second portion 122 is a transition region between the second portion 122 and the second opening 1221, has a step, and is disadvantageous in ensuring flatness.
[0077] In one viable embodiment, as shown in Figures 7 and 8, the non-display area NA includes a plurality of second apertures 1221, which are arranged along the circumferential direction of the display area AA. The touch wiring 151 includes a first segment extending along a first direction, the orthographic projection of some of the second apertures 1221 on the substrate 11 is rectangular, and the dimensions along the first direction of some of the second apertures 1221 are the same. This ensures that the widths of the second portions 122 between the second apertures 1221 through which each first segment passes are relatively consistent, ensuring consistency of the film layer beneath the touch wiring 151, reducing differences between different touch wirings 151, and contributing to ensuring touch quality.
[0078] In the above embodiment, the edges of the display area AA may be rectangles including a long side and a short side, and the first direction may be parallel to the direction of the long side.
[0079] In the above embodiment, by uniformly arranging the multiple second openings 1221 in the non-display area NA, the differences between each first segment can be reduced.
[0080] In the above embodiment, the orthographic area of at least a portion of the second aperture 1221 on the substrate 11 is larger than the orthographic area of the first aperture 1211 on the substrate 11. By setting the area of the second aperture 1221 to be larger, the flatness of the film layer below the touch wiring 151 can be improved, and the yield of the touch wiring 151 can be improved.
[0081] The first aperture 1211 is for housing the light-emitting unit 13, and the orthographic area of the first aperture 1211 on the substrate 11 corresponding to different colored light-emitting units 13 may be the same or different. The orthographic area of at least some of the second apertures 1221 on the substrate 11 must be larger than the orthographic area of the largest first aperture 1211 on the substrate 11, thereby improving the flatness of the film layer below the touch wiring 151.
[0082] In the above embodiment, the extending direction of the portion of the second part 122 located between two adjacent second openings 1221 along the circumferential direction of the display area AA intersects with the extending direction of the touch wiring 151, and the orthographic projection on the substrate 11 of the portion of the second part 122 located between two adjacent second openings 1221 along the circumferential direction of the display area AA is the first projection, which partially overlaps with the orthographic projection on the substrate 11 of the touch wiring 151. That is, one touch wiring 151 passes over a plurality of second openings 1221 along its own longitudinal direction.
[0083] In one viable embodiment, as shown in Figures 2 and 4, the isolation structure 12 includes a first isolation section 123 and a second isolation section 124, the second isolation section 124 being located on the side of the first isolation section 123 away from the substrate 11, and the orthographic projection of the second isolation section 124 on the substrate 11 overlaps the orthographic projection of the first isolation section 123 on the substrate 11.
[0084] In the above embodiment, the first portion 121 and the second portion 122 of the isolation section may both include the first isolation section 123 and the second isolation section 124.
[0085] In the above embodiment, a step is formed between the first isolation portion 123 and the second isolation portion 124, thereby separating the light-emitting functional layer 132 and the second electrode 133 within the display area AA, ensuring that the light-emitting functional layers 132 in adjacent light-emitting units 13 are independent of each other, and that the second electrodes 133 in adjacent light-emitting units 13 are independent of each other. Furthermore, instead of separating the light-emitting material layer 1320 and the shield layer 14 within the display area NA, the light-emitting functional layer 132 can be formed simultaneously with the light-emitting material layer 1320, which is manufactured in the same single layer as the light-emitting functional layer 132.
[0086] In the above embodiment, since the second electrodes 133 are independent of each other, it is difficult to supply power to each second electrode 133. By electrically connecting at least some of the second electrodes 133 via the first part 121 of the isolation structure 12 and then supplying power synchronously, synchronous power supply to each second electrode 133 is achieved, simplifying the number of power supply lines and the manufacturing process. At the same time, since magnesium-silver alloy is often selected as the material for the second electrodes 133, and the material for the isolation structure 12 contains aluminum, which has lower electrical resistance than magnesium-silver alloy, the electrical connection method of the isolation structure 12 and the second electrodes 133 is adopted to have lower electrical resistance than conventional single-sided second electrodes 133, thereby reducing the power consumption of the display panel 1. This reduces the difference due to attenuation (IR-DROP) in the signal transmission process between the proximity drive end and the principle drive end, which is due to high electrical resistance, and contributes to improving the uniformity of the panel display.
[0087] In the above embodiment, the shield layer 14, after being blocked by the second portion 122, forms a first sub-portion 141 located within the second opening 1221 and a second sub-portion 142 located on the side of the second branch 1322 away from the second portion 122. The electrical connection between the second portion 122 and the second sub-portion 142 enables the electrical connection of multiple second sub-portions 142, thereby facilitating synchronous power supply between the second portion 122 and the second sub-portions 142, forming a sealed film layer, and realizing a shielding function.
[0088] In one viable embodiment, as shown in Figures 2 and 4, the pixel definition layer 17 further includes a portion of the pixel definition layer 17 located in the display area AA, which is formed on the side of the first electrode 131 away from the substrate 11, and a portion of the pixel definition layer 17 located in the non-display area NA, which is in contact with the substrate 11. The pixel definition layer 17 includes a pixel limiting portion 171 and a plurality of pixel apertures 172 located in the display area AA, the pixel apertures 172 being provided opposite the first aperture 1211.
[0089] In the above embodiment, the portion of the pixel definition layer 17 located in the display area AA covers the edge of the first electrode 131, thereby protecting the first electrode 131, achieving mutual insulation between adjacent first electrodes 131, and reducing interference between adjacent first electrodes 131. The portion of the pixel definition layer 17 located in the display area AA includes at least a first pixel aperture 172, a second pixel aperture 172, and a third pixel aperture 172. Specifically, if the display panel 1 includes three-color light-emitting units 13, the first pixel aperture 172 is used to form a red light-emitting unit 13, the second pixel aperture 172 is used to form a green light-emitting unit 13, and the third pixel aperture 172 is used to form a blue light-emitting unit 13. If the display panel 1 further includes a white light-emitting unit 13, the pixel definition layer 17 may further include a fourth pixel aperture 172 for forming the white light-emitting unit 13.
[0090] The portion of the pixel definition layer 17 located in the non-display area NA comes into contact with the substrate 11, providing a flat surface for subsequent film layers, improving the reliability of the touch wiring 151, and reducing the occurrence of defects such as circuit breaks and short circuits.
[0091] If the display panel 1 includes an isolation structure 12, the use of masks can be omitted and costs reduced by first manufacturing each color light-emitting unit 13 in one layer and then patterning it. Different color light-emitting units 13 are manufactured in different orders, and the isolation structure 12 can isolate the light-emitting units 13 that are manufactured later during the patterning process, improving the yield of the patterning process and reducing the impact of patterning on the yield of the light-emitting units 13. In the manufacturing process of the last color light-emitting unit 13, the portion located in the non-display area NA of the light-emitting functional layer 132 and the second electrode 133 is retained, and the light-emitting material layer 1320 and shield layer 14 are formed. This allows the light-emitting material layer 1320 and shield layer 14 to be manufactured based on the original manufacturing process, eliminating the need to add new materials to the manufacturing process and saving manufacturing costs.
[0092] The present application further provides a display device 2, which includes a display panel 1 according to any of the above embodiments of the present application, as shown in Figure 9. In the display device 2, a good shielding effect can be achieved between the touch wiring 151 and the portion of the signal lines located in the non-display area NA within the substrate 11, reducing interference between the two and improving the yield of the display device 2.
[0093] The display device 2 may be a mobile terminal such as a mobile phone or laptop computer, a fixed terminal such as a television or computer display, or a wearable device such as a wristwatch, and this application is not particularly limited.
[0094] The present invention further provides a method for manufacturing a display panel including a display area and a non-display area provided so as to surround at least a portion of the display area. As shown in Figure 10, the manufacturing method includes the following steps.
[0095] S100 provides a substrate 11.
[0096] In S200, an isolation structure 12 is formed on one side of the substrate 11. The isolation structure 12 includes a first portion 121 located in the display area AA and a second portion 122 located in the non-display area NAAA. The first portion 121 surrounds and forms a first opening 1211, and the second portion 122 surrounds and forms a second opening 1221.
[0097] In S300, a light-emitting unit 13 is formed within the first aperture.
[0098] In S400, a shield layer 14 is formed on the side of the isolation structure 12 away from the substrate 11, and at least a portion of the shield layer 14 is formed in the second opening 1221 and is electrically connected to the second portion 122.
[0099] In S500, a conductive layer is formed on the side of the shielding layer 14, the light-emitting unit 13, and the isolation structure 12 that is away from the substrate 11.
[0100] In a display panel manufactured by the manufacturing method according to the present invention, a continuous film layer can be formed between the second portion 122 located within the non-display area NA of the isolation structure and the shield layer 14. This achieves mutual shielding between the portion of the conductive layer 15 located within the non-display area NA and the signal lines 111 within the non-display area NA of the substrate 11. This reduces mutual interference between the signals in the portion of the conductive layer 15 located within the non-display area NA and the signals in the signal lines 111 within the substrate 11, thereby improving the yield of the display panel 1. This further enhances the user experience.
[0101] The embodiments described herein do not describe all details in detail, nor do they limit the application to specific embodiments. It is clear from the above description that many modifications and changes are possible. These embodiments are selected and described herein specifically for the purpose of better interpreting the principles and practical applications of the application, and to enable those skilled in the art to use the application and modify and apply it.
