[0002] This disclosure claims priority to PCT application filed on January 26, 2022, with application number PCT / CN2022 / 074113 entitled "Touch Structure, Touch Display Panel and Display Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of touch technology, and more specifically, to a touch structure, a touch display panel, and a display device. Background Technology

[0004] Touch display panels are widely used in terminal devices such as mobile phones and tablets. While displaying images, they can also enable human-computer interaction through touch operations. The touch position is determined by the change of sensing capacitance to realize touch operation. However, existing touch display panels are prone to touch failure, errors and other abnormal phenomena.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0054] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0055] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0056] In this document, the row direction X and column direction Y are simply two intersecting directions. They can be perpendicular to each other or form an angle, which can be between 80° and 110°. In the accompanying drawings, the row direction X can be horizontal and the column direction Y can be vertical, but they are not limited thereto. If the touch structure is rotated, the actual orientation of the row direction X and the column direction Y may change. The X direction in the accompanying drawings exemplarily shows the row direction, and the Y direction exemplarily shows the column direction. Furthermore, the term "adjacent" to A and B as described herein means that there are no other A or B between A and B. For example, an adjacent first electrode block and a second electrode block mean that there are no other first electrode blocks and other second electrode blocks between them.

[0057] This disclosure provides a touch structure that can be disposed on one side of a display substrate. The display substrate is used to display images and can be an organic electroluminescent display substrate, a liquid crystal display substrate, or other devices capable of displaying images; no particular limitation is made herein. The touch structure can be used to sense touch operations, determine the touch position, and thereby display the corresponding image on the display substrate.

[0058] like Figure 1 and Figure 2As shown, the touch structure disclosed herein is a mutual capacitance structure, which may include multiple first touch electrodes Tx and multiple second touch electrodes Rx. Each first touch electrode Tx may be spaced apart along the row direction X, and each second touch electrode Rx may be spaced apart along the column direction Y. Each first touch electrode Tx and each second touch electrode Rx may include multiple electrode blocks connected in series. Any first touch electrode Tx may include multiple first electrode blocks Txc connected in series along the column direction Y, and two adjacent first electrode blocks Txc in the column direction Y are connected in series through a transition bridge BR. Any second touch electrode Rx may include multiple second electrode blocks Rxc connected in series along the row direction X, and two adjacent second electrode blocks Rxc can be connected in series through a connecting portion Rxo.

[0059] Each first electrode block Txc and second electrode block Rxc is arrayed. At least a portion of the first electrode blocks Txc are adjacent to different second electrode blocks Rxc in two different directions intersecting with the row direction X and the column direction Y. Correspondingly, at least a portion of the second electrode blocks Rxc are adjacent to different first electrode blocks Txc in two different directions intersecting with the row direction X and the column direction Y.

[0060] A gap exists between adjacent first electrode blocks Txc and second electrode blocks Rxc, thereby forming a capacitor. To increase the area directly opposite each other between the first electrode blocks Txc and Rxc, the edges of the first electrode blocks Txc and Rxc can have interdigitated fingers FI distributed circumferentially. In adjacent first electrode blocks Txc and Rxc, a portion of the interdigitated fingers FI of the first electrode block Txc can be located between a portion of the interdigitated fingers FI of the second electrode block Rxc, but without contact. This allows the interdigitated fingers FI of the first electrode block Txc and the second electrode block Rxc to be arranged alternately. The interdigitated fingers FI make the extension trajectory of the gap between the first electrode blocks Txc and Rxc more tortuous, increasing the area directly opposite each other without increasing the area of ​​the first electrode blocks Txc and Rxc. This is beneficial for increasing the capacitance between them and improving the sensitivity of touch operation.

[0061] A capacitor can be formed between any two adjacent first electrode blocks Txc and second electrode blocks Rxc. When a finger performs a touch operation, the capacitance at the touch position changes. The touch position can be determined by sensing the change in capacitance corresponding to the first touch electrode Tx and the second touch electrode Rx. The detailed principle will not be described in detail here.

[0062] like Figure 1As shown, each first touch electrode Tx can be connected to a different signal terminal via different leads, and each second touch electrode Rx can also be connected to a different signal terminal via different leads, so as to transmit and receive signals through the first touch electrode Tx and the second touch electrode Rx. For example, the first touch electrode Tx can be used as a driving electrode to receive driving signals, and the second touch electrode Rx can be used as a sensing electrode to output sensing signals. Of course, the functions of the first touch electrode Tx and the second touch electrode Rx can be interchanged.

[0063] like Figure 1 and 2 As shown, the aforementioned electrode blocks and connecting portions Rxo can be located in the same electrode layer TMB, which can be formed simultaneously in a single patterning process. That is, the electrode layer TMB includes the electrode block of the first touch electrode Tx and the second touch electrode Rx. To avoid short circuits between the first touch electrode Tx and the second touch electrode Rx, the transition bridge BR can be located on one side of the electrode layer TMB; that is, the transition bridge BR is on a different layer from the electrode layer TMB. Simultaneously, an insulating layer IN is provided between the transition bridge BR and the electrode layer TMB, thus separating them. The first touch electrode Tx can intersect with the second touch electrode Rx at the transition bridge BR. Furthermore, the transition bridge BR can intersect with the connecting portion Rxo. In addition, the transition bridge BR can be connected to the first electrode block Txc through a via Ho penetrating the insulating layer IN.

[0064] like Figures 1-2 As shown, in some embodiments of this disclosure, each transition bridge BR can be disposed on the light-emitting side of the display substrate PNL and can be formed simultaneously. Each transition bridge BR has the same thickness and is made of the same material, thus allowing for simultaneous formation. An insulating layer IN can cover each transition bridge BR and protrude at positions corresponding to the transition bridge BR, but is not interrupted; that is, the insulating layer IN can undulate with the presence of the transition bridge BR. An electrode layer TMB can be disposed on the surface of the insulating layer IN facing away from the display substrate PNL. Each transition bridge BR can be connected to the same first electrode block Txc through one or more vias Ho penetrating the insulating layer IN.

[0065] like Figure 1 and Figure 3 As shown, in the same first touch electrode Tx, the number of transition bridges BR connecting two adjacent first electrode blocks Txc can be one or more. If there are multiple transition bridges BR, the multiple transition bridges BR can be distributed side by side along the row direction X, and all of them intersect with the same connection part Rxo in space. That is, the two intersect on the orthographic projection of the two on the display substrate PNL, but are not actually connected, so as to prevent the first touch electrode Tx and the second touch electrode Rx from being connected and causing a short circuit.

[0066] like Figure 3As shown, in some embodiments of this disclosure, both the first electrode block Txc and the second electrode block Rxc can embed a dummy electrode Dum. For example, the first electrode block Txc and the second electrode block Rxc have a hollow area, which is a through-hole structure that penetrates the electrode layer. The dummy electrode Dum is located in the hollow area and is disposed in the same layer as the first electrode block Txc and the second electrode block Rxc. One or more dummy electrodes Dum can be provided in the hollow area, and each dummy electrode Dum is in a floating state, that is, it is not electrically connected to any other structure and does not receive any electrical signals.

[0067] Both the transition bridge (BR) and the electrode layer (TMB) can be single-layer or multi-layer conductive structures. For example, the transition bridge (BR) may include two outer layers and an intermediate layer between the two outer layers. The outer layers can be made of titanium, and the intermediate layer can be made of aluminum, i.e., the transition bridge (BR) has a Ti / Al / Ti structure; or, the outer layers can be made of indium tin oxide (ITO), and the intermediate layer can be made of aluminum, i.e., the transition bridge (BR) has an ITO / Ag / ITO structure. Similarly, if the electrode layer (TMB) is a multi-layer structure, it can also be a Ti / Al / Ti structure or an ITO / Ag / ITO structure.

[0068] The material of the insulating layer IN can be silicon nitride, or it can be silicon oxide, silicon oxynitride, or other inorganic or organic insulating materials.

[0069] In addition, such as Figure 2 As shown, in some embodiments of this disclosure, the touch structure may further include a buffer layer BA and a protective layer TOC. The buffer layer BA can serve as the substrate of the touch structure and can be disposed on the light-emitting side of the display substrate PNL. Its material may include insulating materials such as silicon nitride and silicon oxide. The transition bridge BR can be disposed on the surface of the buffer layer BA facing away from the display substrate PNL. The protective layer TOC can cover the areas of the electrode layer TMB and the insulating layer IN that are not covered by the electrode layer TMB. The protective layer TOC is used to protect the electrode layer TMB, and its material may be a transparent insulating material such as polyimide (PI) or optical adhesive.

[0070] like Figure 1 as well as Figures 5-11As shown, to reduce obstruction of the light emitted by the PNL on the display substrate, both the first touch electrode Tx and the second touch electrode Rx can be made into a mesh structure formed by multiple grid lines. Each grid line can extend in a straight line, but the direction can be different. The grid lines of the first electrode block Txc and the second touch electrode Rx can be defined as channel lines TL, and the grid lines of the transition bridge BR can be defined as transition lines BL. The aforementioned mesh structure has multiple mesh openings NEh, each mesh opening NEh is surrounded by multiple grid lines. For example, any mesh opening NEh of the electrode layer TMB can be surrounded by multiple channel lines TL, and any mesh opening NEh of the transition bridge BR can be surrounded by multiple transition lines BL. The mesh openings NEh can be polygonal, such as rhombuses or hexagons, etc., without special limitation. Each side of the polygon is a grid line. In addition, the dummy electrode Dum can also be a mesh structure and can be formed simultaneously with the first electrode block Txc and the second touch electrode Rx.

[0071] It should be noted that, since grid lines have width, the aforementioned polygons are not limited to the shape of standard geometric polygons, and the vertices of the polygons are not points in the geometric sense, but refer to the areas where grid lines intersect.

[0072] like Figures 5-11 As shown, the electrode layer TMB is broken at a portion of the channel line TL, thereby separating the first electrode block Txc and the second touch electrode Rx. In other words, the gap between adjacent first electrode blocks Txc and second touch electrodes Rx can be formed by breaking the channel line TL. Breaking the channel line TL can be achieved by removing a local area of ​​the channel line TL or by removing the entire channel line TL. Figures 5-11 The dashed line S in the figure shows the extension path of the gap between the first electrode block Txc and the second touch electrode Rx. This extension path is only for illustration and is not a limitation on the actual extension path.

[0073] The gap between the first electrode block Txc and the adjacent second touch electrode Rx can be formed by the aforementioned disconnection method. The boundary between the first electrode block Txc and the second touch electrode Rx can be formed by a portion of the channel line TL, that is, the outermost channel line TL of the first electrode block Txc and the second touch electrode Rx forms their boundary, wherein the boundary of the second touch electrode Rx includes the boundary of the second electrode block Rxc and the boundary of the connecting portion Rxo.

[0074] In a bridge BR and its connected first electrode block Txc and intersecting second touch electrode Rx, the bridge BR spans the gap between the second touch electrode Rx and the first electrode block Txc and the second touch electrode Rx, and connects to the first electrode block Txc. The width of the gap spanned by the bridge BR can be equal to the length of a connecting wire BL, and the bridge BR has multiple connecting wires BL opposite to this gap. That is, the orthographic projection of a portion of the connecting wires BL of the bridge BR onto the display substrate PNL is located within the gap between the first electrode block Txc and the second touch electrode Rx, which is within the orthographic projection gap of the display substrate PNL. This allows the bridge BR to span the second touch electrode Rx in space and connect to the first electrode block Txc.

[0075] like Figures 5-11 As shown, a transition bridge BR may include at least two opening portions BRh and a bridge portion BRb connecting the two opening portions BRh. The at least two opening portions BRh are respectively connected to two first electrode blocks Txc connected to the transition bridge BR, and the opening portions BRh and the first electrode blocks Txc can be connected through vias Ho. The bridge portion BRb is arranged to cross the second touch electrode Rx, but remains insulated. For example, the bridge portion BRb may cross the connecting portion Rxo.

[0076] In some embodiments of this disclosure, for a transition bridge BR, there are two openings BRh, which are connected to both ends of the bridge portion BRb, and the two openings BRh are respectively connected to the two first electrodes Txc of the transition bridge BR.

[0077] In some other embodiments of this disclosure, for a bridge BR, the number of openings BRh is greater than two, and at least two or more openings BRh can be connected at one end of the bridge portion BRb, so that a bridge BR can be connected to a first electrode Txc through multiple openings BRh.

[0078] For ease of description, the channel line TL forming the boundary of the first electrode block Txc can be defined as the first boundary channel line TL1, and the channel line TL forming the boundary of the second electrode block Rxc can be defined as the second boundary channel line TL2. Meanwhile, the partial adapter line BL of the opening portion BRh can be defined as the boundary adapter line BL1.

[0079] For the interconnected opening portion BRh and the first electrode block Txc, the boundary transition line BL1 can overlap with a portion of the first boundary channel line TL1, and the overlapping transition line BL and the channel line TL extend in the same direction.

[0080] like Figures 5-11As shown, in some embodiments of this disclosure, the area where the channel lines TL of the first electrode block Txc intersect is a channel intersection area, and the area where the different transition lines BL of the transition bridge BR intersect is a transition intersection area. The boundary of the first electrode block Txc has multiple channel intersection areas, and the channel intersection areas of the boundary of the first electrode block Txc overlap with at least a portion of the transition intersection areas in a one-to-one correspondence.

[0081] The transition junction area of ​​the aperture section BRh can be defined as the transition crossover section BRc. Adjacent transition lines BL of the aperture section BRh can be connected through the transition crossover section BRc. Simultaneously, the channel junction area overlapping with the transition crossover section BRc can be defined as the channel crossover section TLc. Adjacent channel lines TL of the channel crossover section TLc can be connected through the channel crossover section TLc. The overlapping transition crossover sections BRc and channel crossover sections TLc are connected by vias Ho.

[0082] The channel intersection TLc can be an integral structure with the channel line TL. It can be a sheet-like structure with a polygonal or circular shape. The width of the channel intersection TLc in the direction perpendicular to the channel line TL it connects to can be greater than the width of the channel line TL. Similarly, the transition intersection BRc can be an integral structure with the transition line BL. It can also be a sheet-like structure with a polygonal or circular shape. The width of the transition intersection BRc in the direction perpendicular to the transition line BL it connects to can be greater than the width of the transition line BL, thus providing more space for the via Ho and preventing the via Ho from cutting off the grid lines.

[0083] The distribution of mesh NEh is illustrated below using the basic structure of a display substrate PNL as an example:

[0084] like Figures 5-11 and Figure 12As shown, the display substrate PNL can have multiple light-emitting units, and each light-emitting unit can include multiple independently emitting sub-pixels SP. The same light-emitting unit includes at least multiple sub-pixels SP with different emitting colors. The aforementioned mesh NEh can be correspondingly set with the sub-pixels SP of the display substrate PNL. Each mesh NEh has at least one sub-pixel SP in its orthographic projection on the display substrate PNL. The light emitted by the sub-pixel SP can be emitted from the mesh NEh, reducing the obstruction of the light emission of the display substrate PNL by the touch structure. For example, the display substrate PNL can be an electroluminescent organic light-emitting display substrate, i.e., an OLED display substrate, which may include a driving backplane BP and a light-emitting device layer OL located on one side of the driving backplane BP. The light-emitting device layer OL may include multiple arrayed light-emitting devices, which may be organic light-emitting diodes. In some embodiments, each light-emitting device emits light independently and the colors may be different. In this case, one light-emitting device may be a sub-pixel SP. In other embodiments, the light-emitting devices emit the same color. In this case, the display substrate PNL may also include a color filter layer, which may include a filter section corresponding to each light-emitting device. The filter section may emit only monochromatic light, and the filter section and its corresponding light-emitting device may be a sub-pixel SP.

[0085] It should be noted that the aforementioned light-emitting units are defined only for the convenience of describing the distribution of sub-pixels SP, and are not limited to being the basic unit for displaying an image. When displaying an image, each sub-pixel SP can be divided into multiple pixels, and each pixel includes at least three colors of sub-pixels SP. Adjacent pixels can share some sub-pixels SP, that is, one sub-pixel SP in a light-emitting unit can be shared by two different pixels, and the image is displayed through the subpixel rendering (SPR) algorithm. Of course, different pixels can also not share sub-pixels SP, in which case the light-emitting unit can act as a pixel.

[0086] like Figures 5-8 As shown, in some embodiments of this disclosure, the display substrate PNL is an electroluminescent organic light-emitting display substrate PNL, specifically, as... Figure 12 As shown, the same light-emitting unit may include four sub-pixels SP, namely one red sub-pixel GSP, one blue sub-pixel BSP, and two green sub-pixels GSP. The red sub-pixel RSP and the blue sub-pixel BSP may be distributed along the column direction Y, and the blue sub-pixel BSP is larger than the red sub-pixel RSP. The two green sub-pixels GSP are distributed along the row direction X on both sides of the red sub-pixel RSP and the blue sub-pixel BSP, and the areas of the two green sub-pixels GSP are equal. The center line connecting the four sub-pixels SP may be quadrilateral, such as rectangle, rhombus, and trapezoid, etc. The outline of each sub-pixel SP may also be quadrilateral, such as rectangle, rhombus, and trapezoid, etc., but the area of ​​the green sub-pixel GSP is smaller than that of the red sub-pixel RSP.

[0087] Accordingly, the mesh NEh of the touch structure can be polygonal, such as rectangular, rhomboid, and trapezoidal. Each sub-pixel SP corresponds to only one mesh NEh, allowing light to pass through that mesh NEh. The shape of any sub-pixel SP is the same as the shape of its corresponding mesh NEh. If both are polygonal, the sides of the sub-pixel SP are parallel to the sides of the mesh NEh (i.e., the grid lines that form the mesh NEh). The mesh NEh corresponding to the green sub-pixel SP is smaller than the mesh NEh corresponding to the red sub-pixel SP, and the mesh NEh corresponding to the blue sub-pixel SP is larger than the mesh NEh corresponding to the red sub-pixel SP. Of course, the shape and size of each mesh NEh can be the same, as long as it is larger than the corresponding sub-pixel SP, it can avoid obscuring the sub-pixel SP.

[0088] In an opening portion BRh and its connected first electrode block Txc, the number of vias Ho connecting the opening portion BRh and the first electrode block Txc can be the same as the number of vertices of a mesh NEh, and each via Ho corresponds one-to-one with the channel intersection TLc and transition intersection BRc located at each vertex. Some of the vias Ho can be located on the boundary of the first electrode block Txc. For example, one or two vias Ho can be located on the boundary of the first electrode block Txc, while other vias Ho are not on the boundary of the first electrode block Txc. In this case, only a portion of the transition lines BL in the opening portion BRh are boundary transition lines BL1, extending along the boundary of the first electrode block Txc.

[0089] like Figures 9-10 As shown, in some other embodiments of this disclosure, the display substrate PNL is still an electroluminescent organic light-emitting display substrate PNL, and its sub-pixels can be arranged in a GGRB pattern. Specifically, the same light-emitting unit can include four sub-pixels, namely one red sub-pixel, one blue sub-pixel and two green sub-pixels. The red sub-pixel and the blue sub-pixel can be distributed along the row direction X, and both of them are hexagonal in shape. The area of ​​the blue sub-pixel is larger than the area of ​​the red sub-pixel. The two green sub-pixels are distributed along the column direction Y between the red sub-pixel and the blue sub-pixel, and both of the green sub-pixels are pentagonal in shape and have equal areas. The area of ​​the green sub-pixel is smaller than that of the red sub-pixel and the blue sub-pixel.

[0090] Accordingly, each sub-pixel corresponds to only one mesh NEh, allowing light to pass through that mesh NEh. The shape of any sub-pixel is the same as the shape of its corresponding mesh NEh. If both are polygons, the sides of the sub-pixel are parallel to the sides of the mesh NEh (i.e., the grid lines that form the mesh NEh) in a one-to-one correspondence. The mesh NEh corresponding to the green sub-pixel is smaller than the mesh NEh corresponding to the blue and red sub-pixels, and the mesh NEh corresponding to the blue sub-pixel is smaller than the mesh NEh corresponding to the red sub-pixel.

[0091] In an opening portion BRh and its connected first electrode block Txc, there are multiple vias Ho, such as four or five, and each via Ho can be located on the boundary of the first electrode block Txc. In this case, each adapter line BL of the opening portion BRh is a boundary adapter line BL1, and extends along the boundary of the first electrode block Txc, that is, along the first boundary channel line TL1.

[0092] Regarding the aforementioned touch structure, the inventors discovered that the adapter bridge BR of the touch structure can be fabricated through processes such as deposition, exposure, development, and etching. During this process, the cross-section of the adapter line BL is trapezoidal, meaning that the sidewalls of the adapter line BL contract away from the display substrate PNL. Correspondingly, the insulating layer IN forms a trapezoidal protrusion at the position corresponding to the sidewall of the adapter line BL. The sidewalls of this protrusion are similar to those of the adapter line BL, also contracting away from the substrate. When forming the electrode layer TMB, in addition to the required pattern, residual material of the electrode layer TMB will exist on the outer side of the sidewall corresponding to the protrusion, i.e., on the outer side of the sidewall corresponding to the adapter line BL. This residual material can extend along the sidewall of the adapter line BL, thereby connecting the first electrode block Txc and the adjacent second touch electrode Rx, causing a short circuit and resulting in touch abnormalities such as touch malfunction or reduced accuracy.

[0093] In response, based on the above-described implementation method, the inventors have provided a touch structure, such as... Figures 5-11 As shown, by misaligning the boundary adapter line BL1 with the first boundary channel line TL1, the boundary adapter line BL1 guides the direction of the residual material by limiting its position, extending the path required for the residual material to cause a short circuit between the adjacent first electrode block Txc and the second contact electrode, making it easier to disconnect and thus reducing the risk of short circuit. The extension path is shown in SL in the figure.

[0094] The following is a detailed explanation of the boundary adapter line BL1 and the first boundary channel line TL1:

[0095] In the overlapping boundary transition line BL1 and the first boundary channel line TL1, one side of the boundary transition line BL1 is located on the side of the first boundary channel line TL1 closest to the adjacent second electrode block Rxc, causing one side of the boundary transition line BL1 to shift outward rather than align with the first boundary channel line TL1. Simultaneously, the other side of the boundary transition line BL1 is located between the two sides of the first boundary channel line TL1. Thus, forming the electrode layer TMB allows material remaining outside the transition bridge BR to be guided along the outward-shifted side of the boundary transition line BL1, preventing it from directly contacting the first boundary transition line BL1 along the bridge portion BRb. Instead, the material needs to extend along the side of the boundary transition line BL1 away from the bridge portion BRb, thereby lengthening its path and making it easier to disconnect, thus avoiding short circuits. Only residual material on the outer side of the boundary adapter line BL1 near the second electrode block Rxc can cause a short circuit. Even if there is residual material on the outer side away from the second electrode block Rxc, it is difficult to cause a short circuit between the first electrode block Txc and the second electrode block Rxc. Furthermore, the boundary adapter line BL1 has another side located between the two sides of the first boundary channel line TL1, which can prevent both sides of the boundary adapter line BL1 from being located outside the first boundary channel line TL1, thus avoiding an unnecessary increase in the width of the boundary adapter line BL1.

[0096] like Figure 5 As shown, in the first embodiment of this disclosure, each adapter wire BL of the opening portion BRh forms a mesh NEh, and adjacent adapter wires BL are connected by an adapter crossover portion BRc. The two adapter wires BL of the opening portion BRh are boundary adapter wires BL1, and the bridge portion BRb is connected only to an adapter crossover portion BRc that connects the two boundary adapter wires BL1. For example, the opening portion BRh has four adapter wires BL, so that its mesh NEh can be quadrilateral, with adapter wires BL having two boundary adapter wires BL1 and two non-boundary adapter wires BL1.

[0097] In the non-boundary adapter BL1 of the opening portion BRh, the adapter BL and its overlapping channel line TL, one side of the boundary of the adapter BL is located on the side of the channel line TL away from the adjacent second electrode block Rxc, and the other side of the adapter BL is located between the two sides of the channel line TL. For example... Figure 5 As shown, the entire opening section BRh can be shifted so that the adapter line BL and the channel line TL of the opening section BRh are staggered.

[0098] like Figures 6-8As shown, referring to the above-described embodiments, in the second embodiment of this disclosure, the opening portion BRh may have only one adapter line BL1 as the boundary adapter line BL1, and the bridge portion BRb may be connected to the adapter cross portion BRc connected to both ends of the boundary adapter line BL1. Furthermore, the opening portion BRh has four adapter lines BL, so that its mesh NEh can be quadrilateral, having one boundary adapter line BL1 and three non-boundary adapter lines BL1.

[0099] Furthermore, in the interconnected opening portion BRh and the first electrode block Txc: among the first boundary channel lines TL1 of the first electrode block Txc, the first boundary channel lines TL1 located on both sides of the opening portion BRh and adjacent to the opening portion BRh are all disconnected from the opening portion BRh. That is, the channel intersection portions TLc at both ends of the first boundary channel line TL1 that overlap with the boundary transition line BL1 are disconnected from the adjacent first boundary channel line TL1, thereby extending the extension path of the residual material in the electrode layer TMB and reducing the risk of short circuits. The extension path is shown as SL in the figure.

[0100] Furthermore, such as Figure 11 As shown, the second boundary channel line TL2 located on both sides of the opening portion BRh and adjacent to the bridge portion BRb can also be disconnected from the bridge portion BRb, further extending the path required to cause a short circuit due to residual material and reducing the risk of short circuit.

[0101] like Figure 9 and Figure 10 As shown, in the third embodiment of this disclosure, in the interconnected opening portion BRh and the first electrode block Txc, each transition line BL of the opening portion BRh is a boundary transition line BL1, and adjacent boundary transition lines BL1 are connected by a transition intersection BRc. That is, each transition line BL of the opening portion BRh extends along the boundary of the first electrode block Txc, without forming a mesh NEh, and overlaps one-to-one with multiple first boundary channel lines TL1. For example, the opening portion BRh has four transition lines BL, all of which are boundary transition lines BL1. At the same time, the opening portion BRh has four transition intersections BRc, and the four transition lines BL extend along the trajectory of the first boundary channel lines TL1; each of the four transition intersections BRc is provided with a through hole Ho. Further, the mesh of the first electrode block Txc is hexagonal, that is, it is surrounded by six channel lines TL. The four transition cross sections BRc extend along the trajectory of the first boundary channel line TL1 in a zigzag pattern, with two adjacent boundary transition lines BL1 directly connected without being connected through the transition cross sections BRc.

[0102] In other embodiments of this disclosure, in a bridge BR, at least one end of the bridge portion BRb is connected to a plurality of opening portions BRh. The structure of any opening portion BRh can be the same as that of the opening portions BRh in the first to third embodiments described above. For example, at least a portion of the opening portions BRh can be formed by multiple adapter lines BL enclosing a mesh NEh; or, each adapter line BL of at least a portion of the opening portions BRh can be a boundary adapter line BL1, extending along the boundary of the first electrode block Txc. Simultaneously, each adapter line BL of the opening portion BRh can have a through hole Ho at its end.

[0103] Furthermore, such as Figures 5-10 As shown, based on the first to third embodiments and some other embodiments described above, in some embodiments of this disclosure, the distance between the side of the boundary adapter line BL1 closest to the adjacent second electrode block Rxc and the side of the first boundary channel line TL1 closest to the adjacent second electrode block Rxc is a first distance S1, and the distance between the other side of the boundary adapter line BL1 and the side of the first boundary channel line TL1 furthest from the adjacent second electrode block Rxc is a second distance S2. The first distance S1 and the second distance S2 can be made equal, i.e., S1 = S2. Therefore, the first distance S1 and the second distance S2 can be obtained by translating the boundary adapter line BL1, which has the same width as other adapter lines BL. In other words, the boundary adapter line BL1 between the two sides of the first boundary channel line TL1 can be translated outwards, which helps to ensure the uniformity of the width of each adapter line BL1 and reduces the difficulty of the manufacturing process. Either the first distance S1 or the second distance S2 can be 1μm - 1.5μm, for example, 1μm, 1.2μm, 1.3μm, or 1.5μm.

[0104] Furthermore, such as Figures 5-8As shown, based on the first and second embodiments described above and other embodiments of the opening portion BRh having a non-boundary adapter line BL1, in some embodiments of this disclosure, in the adapter line BL of a non-boundary adapter line BL1 of the opening portion BRh and its overlapping channel line TL, the distance between one side of the boundary of the adapter line BL and the side of the channel line TL away from the adjacent second electrode block Rxc is a third distance S3, and the distance between the other side of the adapter line BL and the side of the channel line TL close to the adjacent second electrode block Rxc is a fourth distance S4. The third distance S3 and the fourth distance S4 can be made equal, i.e., S3=S4. Either the third distance S3 or the fourth distance S4 can be 1μm-1.5μm, for example, 1μm, 1.2μm, 1.3μm or 1.5μm. Thus, the adapter BL of the non-boundary adapter BL1 of each opening portion BRh can be set off from the channel line TL in the same way. Of course, the first distance S1, the second distance S2, the third distance S3 and the fourth distance S4 can be made equal. Thus, the first distance S1, the second distance S2, the third distance S3 and the fourth distance S4 can be obtained by translating the adapter BL without changing its width.

[0105] To further extend the extension path of the residual material in the electrode layer TMB, in the overlapping transition cross portion BRc and channel cross portion TLc, the boundary of the transition cross portion BRc can be located inside the boundary of the channel cross portion TLc. That is, the boundary of the orthographic projection of the transition cross portion BRc onto the display substrate PNL is located inside the boundary of the orthographic projection of the channel cross portion TLc onto the display substrate PNL, and the distance between the two boundaries can be 1μm-1.5μm, for example 1μm, 1.2μm, 1.3μm or 1.5μm, and this distance can be equal to the first to fourth distances S4 mentioned above.

[0106] Based on any of the above implementation methods, such as Figure 9 and Figure 10 As shown, in some embodiments of this disclosure, the channel line forming the boundary of the second electrode block Rxc can be defined as the second boundary channel line TL2.

[0107] In a second touch electrode Rx and the bridge portion BRb that intersects with it, the second boundary channel lines TL2 located on both sides of the bridge portion BRb and adjacent to the bridge portion BRb are disconnected from the bridge portion BRb. This increases the extension path of the residual material in the electrode layer TMB, thereby increasing the path that could cause a short circuit and reducing the risk of a short circuit. The extension path is shown as SL in the figure.

[0108] Furthermore, the bridge section BRb has a portion of the adapter wire overlapping with the second boundary channel line TL2 in a one-to-one correspondence. In the overlapping adapter wire BL and the second boundary channel line TL2, one side of the adapter wire BL is located on the side of the second boundary channel line TL2 closest to the adjacent first electrode block Txc, and the other side of the adapter wire BL is located between the two sides of the second boundary channel line TL2. That is, a design that misaligns the first boundary channel line TL1 with the boundary adapter wire BL1 can be adopted, causing the second boundary channel line TL2 and its overlapping adapter wire BL to be misaligned, with one boundary of the adapter wire BL located outside the second touch electrode Rx, thereby preventing residual material from contacting the second touch electrode Rx and causing a short circuit.

[0109] In an overlapping adapter line BL and a second boundary channel line TL1, the distance between one side of the boundary of the adapter line BL and the side of the second boundary channel line TL2 away from the second touch electrode Rx is the fifth distance S5. The distance between the other side of the adapter line BL and the side of the second boundary channel line TL2 near the adjacent second touch electrode Rx is the sixth distance S6. The fifth distance S5 and the sixth distance S6 are equal, i.e., S5=S6. Both the fifth distance S5 and the sixth distance S6 can be 1μm-1.5μm, for example, 1μm, 1.2μm, 1.3μm or 1.5μm.

[0110] This disclosure also includes a touch display panel, such as... Figure 2 As shown, it may include a display substrate PNL and a touch structure, wherein:

[0111] The display substrate PNL can be an electroluminescent organic light-emitting display substrate, a liquid crystal display substrate, etc., and its structure is not specifically limited here.

[0112] Taking an electroluminescent organic light-emitting display substrate (PNL) as an example, it may include a driving backplane (BP), a light-emitting device layer (OL), and a packaging layer (TFE), wherein:

[0113] The driving backplane (BP) has a driving circuit that can be used to drive each light-emitting device in the light-emitting device layer (OL) to emit light independently in order to display an image. Simultaneously, the driving backplane (BP) may include pixel areas and a peripheral area located outside the pixel areas; for example, the peripheral area may be a continuous or discontinuous annular region surrounding the pixel areas.

[0114] The driving circuit may include pixel circuits and peripheral circuits. At least some pixel circuits are located within the pixel area; however, some areas of some pixel circuits may be located in the peripheral area. The pixel circuits can be 7T1C, 7T2C, 6T1C, or 6T2C structures, as long as they can drive the light-emitting devices to emit light; no special restrictions are placed on their structure. The number of pixel circuits is the same as the number of light-emitting devices, and they are connected one-to-one with each light-emitting device to control each device to emit light independently. Here, nTmC indicates that a pixel circuit includes n transistors (represented by the letter "T") and m capacitors (represented by the letter "C").

[0115] The peripheral circuit is located within the peripheral area and is connected to the pixel circuit. It is used to input driving signals to the pixel circuit to control the light-emitting device to emit light. The peripheral circuit may include gate driving circuit, source driving circuit, and light-emitting control circuit, and may also include other circuits. The specific structure of the peripheral circuit is not specifically limited here.

[0116] The driving backplane (BP) can be formed from multiple film layers. For example, the driving backplane (BP) may include a substrate and a driving layer disposed on one side of the substrate. The substrate may be a single-layer or multi-layer structure, and it may be a rigid or flexible structure, without special limitation. The driving circuit described above may be located in the driving layer. Taking a top-gate thin-film transistor as an example, the driving layer may include an active layer, a first gate insulating layer, a gate, a second gate insulating layer, an interlayer dielectric layer, a first source / drain layer, a passivation layer, a first planarization layer, a second source / drain layer, and a second planarization layer, wherein:

[0117] An active layer is disposed on a substrate; a first gate insulating layer covers the active layer; a gate is disposed on the surface of the first gate insulating layer away from the substrate and is directly opposite to the active layer; a second gate insulating layer covers the gate and the first gate insulating layer; an interlayer dielectric layer covers the second gate insulating layer; a first source / drain layer is disposed on the surface of the interlayer dielectric layer away from the substrate and includes a source and a drain, which are connected to the active layer; a passivation layer covers the first source / drain layer; a first planarization layer covers the passivation layer; a second source / drain layer is disposed on the surface of the first planarization layer away from the substrate and is connected to the first source / drain layer; a second planarization layer covers the second source / drain layer and the first planarization layer.

[0118] The light-emitting device layer OL is disposed on one side of the driving backplane BP, for example, on the surface of the driving layer facing away from the substrate. The light-emitting device layer OL may include multiple light-emitting devices arrayed within a pixel region and a pixel definition layer defining each light-emitting device, wherein:

[0119] The pixel definition layer can be disposed on one side of the driving backplane BP, for example, on the surface of the second planarization layer facing away from the substrate. The pixel definition layer is used to separate individual light-emitting devices. Specifically, the pixel definition layer can have multiple openings, and the area defined by each opening is the area of ​​one light-emitting device. The shape of the opening, that is, the shape of the outline of the opening projected onto the driving backplane BP, can be a polygon, a smooth closed curve, or other shapes. The smooth closed curve can be a circle, an ellipse, or an oval, etc., and is not specifically limited here.

[0120] A pixel circuit can be connected to at least one light-emitting device, thereby emitting light under the drive of a driving circuit. For example, the light-emitting device can be connected to a second source / drain layer and can emit light under the drive of the driving circuit. The light-emitting device can be an organic light-emitting diode, which may include a first electrode, a light-emitting functional layer, and a second electrode sequentially stacked along a direction away from the driving backplane BP, wherein:

[0121] The first electrode can be located on the same surface of the driving backplane (BP) as the pixel definition layer, and it can serve as the anode of the light-emitting device. Each opening in the pixel definition layer exposes a corresponding first electrode. The first electrode can be a single-layer or multi-layer structure, and its material can include one or more of conductive metals, metal oxides, and alloys.

[0122] The light-emitting functional layer is at least partially disposed within the opening, and may include a hole injection layer, a hole transport layer, a light-emitting material layer, an electron transport layer and an electron injection layer stacked sequentially in a direction away from the driving backplate BP. Visible light is generated by causing holes and electrons to recombine into excitons in the light-emitting material layer, and the excitons radiate photons. The specific light-emitting principle will not be detailed here.

[0123] The second electrode may be covered with a light-emitting functional layer, which can serve as the cathode of the light-emitting device. The second electrode may be a single-layer or multi-layer structure, and its material may include one or more of conductive metals, metal oxides, and alloys.

[0124] Furthermore, each light-emitting device can share the same second electrode. Specifically, the second electrode is a continuous conductive layer covering the light-emitting functional layer and pixel definition layer of each light-emitting device. In other words, the orthogonal projection of the second electrode onto the pixel definition layer covers each opening.

[0125] The encapsulation layer TFE covers the light-emitting device layer OL, protecting it from external water and oxygen corrosion. For example, the TFE can be encapsulated using a thin-film encapsulation method, comprising a first inorganic layer, an organic layer, and a second inorganic layer. The first inorganic layer covers the surface of the light-emitting device layer OL facing away from the driving backplate BP; for example, it may cover the second electrode. The organic layer is disposed on the surface of the first inorganic layer facing away from the driving backplate BP, with its boundary defined inside the boundary of the first inorganic layer. The boundary of the organic layer's orthographic projection on the driving backplate BP can be located in the peripheral region, ensuring that the organic layer covers all light-emitting devices. The second inorganic layer covers both the organic layer and the first inorganic layer not covered by the organic layer. The second inorganic layer blocks water and oxygen intrusion, while the flexible organic layer achieves planarization.

[0126] The touch structure can be located on the side of the encapsulation layer TFE facing away from the driving backplane BP. For example, the buffer layer BA can be located on the surface of the encapsulation layer TFE facing away from the driving backplane BP. The orthogonal projection of the touch structure onto the driving backplane BP must at least cover the pixel area. The specific structure of the touch structure can be referred to the implementation method of the touch structure described above, and will not be repeated here. The mesh NEh of the electrode layer TMB in the touch structure can be configured one-to-one with each light-emitting device; the specific implementation method can be referred to the implementation method of the touch structure described above.

[0127] Furthermore, in some embodiments of this disclosure, the touch display panel may also include a polarizing layer and a transparent cover plate, wherein: the polarizing layer is a circular polarizer that reduces the reflection of external light, and its specific principle is not described in detail. The transparent cover plate can be adhered to the polarizing layer and can achieve planarization. The transparent cover plate is used to protect the underlying film layer, and its material can be a transparent material such as glass or acrylic, without special limitation.

[0128] This disclosure also provides a display device, which may include the touch display panel of any of the above embodiments. The specific structure and beneficial effects of the touch display panel can be found in the above description of the touch structure and the implementation of the touch display panel, and will not be described in detail here. The display device disclosed herein may be an electronic device with touch display function, such as a mobile phone or a tablet computer, and will not be listed one by one here.

[0129] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
