Description

Display touch modules and electronic devices

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on August 31, 2023, with application number 202311138335.5 and application name “Display Touch Module and Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the display field, and in particular to a display touch module and an electronic device. Background Art

[0003] Currently, flexible display panels are widely used in foldable electronic devices, but these devices often face folding reliability issues. During the bending process, the various film layers of a foldable device experience varying degrees of stress and deformation, with these stresses and deformations increasing as the bending radius decreases. If the stress or deformation of a film layer exceeds its failure threshold during bending, it can crack or even peel, ultimately causing the folding function to fail and resulting in severe display defects such as black spots or a black screen.

[0004] Furthermore, flexible display panels can also be used in candy-bar phones, such as double-sided curved display panels and quad-curved display panels. These new form factors often require a 3D cover. If the display panel itself has poor deformation resistance, cracks can easily form at curved edges and corners when attached to the cover, ultimately leading to display panel packaging failure, resulting in black spots or a black screen.

[0005] Touch on Encapsulation (TOE) technology can improve the bending and deformation capabilities of the display panel body, but the fluidity of the new organic materials is relatively large, and the yield of TOE technology is greatly reduced compared to that of inorganic TOE technology.

[0006] Summary of the Invention

[0007] The embodiments of the present application provide a display touch module and an electronic device, which improve the bending and deformation capability while taking into account the yield rate of the touch integration on the device.

[0008] In a first aspect of an embodiment of the present application, a display touch module is provided, comprising: a display panel, and an organic layer disposed on the display panel, the organic layer comprising a first organic layer and a second organic layer, the display touch module further comprising a first metal layer and a second metal layer, the first metal layer being disposed within the first organic layer, and the second metal layer being disposed within the second organic layer; the first metal layer comprising a first electrode, the second metal layer comprising a second electrode, the first electrode and the second electrode being configured to output a first signal upon detecting a touch operation; the projection of the first electrode on the second metal layer and the second electrode being arranged alternately along a first direction and a second direction, respectively, the first direction being perpendicular to the second direction. Thus, the organic layer, the first metal layer, and the second metal layer constitute a touch integrated layer, the organic layer being configured to encapsulate the first metal layer and the second metal layer. Compared to an inorganic encapsulation layer, the organic layer has greater deformation capability, thereby reducing the risk of fracture of the display touch module during large strain or deformation. Furthermore, placing the first and second electrodes on separate layers eliminates the need for a large number of bridging micropores in the organic layer, compared to placing them on the same layer. This prevents residual pores due to insufficient resolution in the organic material, thereby reducing the risk of signal interruption caused by residual pores and improving product yield. Furthermore, the projection of the first electrode on the second metal layer interlocks with the second electrode, forming a checkerboard pattern, reducing the driving load on the touch control module.

[0009] In one optional implementation, each first electrode has a constant size along the first direction and the second direction, and each second electrode has a constant size along the first direction and the second direction. Thus, the constant size of a single electrode in the first and second directions ensures uniform signal strength across the screen when the stylus is swiped across the screen, resulting in superior active pen performance and improved linearity.

[0010] In one optional implementation, both the first and second electrodes employ a square pattern. This allows for uniform dimensions of the individual electrodes in both the first and second directions, ensuring uniform signal strength across the screen when the stylus is swiped across the screen, resulting in superior active pen performance and improved linearity.

[0011] In one optional implementation, the display panel includes: a plurality of pixel regions arranged in an array; a first electrode including a plurality of first sub-metal conductors, the plurality of first sub-metal conductors forming a plurality of metal grids; and a second electrode including a plurality of second sub-metal conductors, the plurality of second sub-metal conductors forming a plurality of metal grids, the plurality of metal grids corresponding to the plurality of pixel regions. Thus, both the first and second electrodes utilize a metal grid structure, allowing the metal grids to be positioned directly opposite and surrounding the pixel regions, thereby effectively preventing the metal conductors from overlapping the pixel regions and affecting the display brightness of the pixel regions.

[0012] In one optional implementation, the plurality of first electrodes extend along a third direction, and the plurality of second electrodes extend along a fourth direction, wherein the third and fourth directions intersect, and the overlap width of the first and second electrodes at their intersections is greater than or equal to the line width of the metal mesh; and the overlap width of the first and second electrodes at their non-intersecting locations is less than the line width of the metal mesh. As a result, the overlap width between the first and second electrodes is only at the level of the line width, reducing the overlap width between the first and second electrodes. This effectively reduces the induced capacitance between the first and second sub-metal conductors in the perpendicular stacking direction, thereby further reducing the drive load of the touch control module.

[0013] In one optional implementation, the metal grid has a line width of 3μm-6μm. This reduces the overlap between the first and second electrodes, effectively lowering the capacitance between the first and second sub-metal conductors in the vertical stacking direction, further reducing the drive load of the touch control module.

[0014] In one optional implementation, the first metal layer further includes a plurality of first floating metal grids, each of which is spaced between adjacent first electrodes and insulated from the first electrodes. Thus, the first floating metal grids reduce the risk of large-scale over-etching of the organic layer at the gap between the first electrodes, reducing the flow of the organic layer above the first metal layer into the gap between the first electrodes. This reduces the loss of the organic layer between the first and second metal layers, thereby reducing the risk of short circuits between the first and second metal layers.

[0015] In an optional implementation, the second metal layer further includes a plurality of second floating metal grids, the second floating metal grids being spaced apart between adjacent second electrodes and insulated from the second electrodes. Thus, the second floating metal grids improve the flatness of the second metal layer.

[0016] In an optional implementation, the projections of the multiple first floating metal grids on the second metal layer completely overlap with the second metal grids; thus, floating metal grids are provided in all gaps in the first metal layer, which can further prevent the second organic layer from flowing into the gaps.

[0017] In an optional implementation, the projections of the multiple first floating metal grids on the second metal layer partially overlap with the second metal grids; thus, setting floating metal grids in partial gaps of the first metal layer can reduce the load of the first metal layer and improve touch performance.

[0018] In an optional implementation, the projections of the plurality of second floating metal grids on the first metal layer completely overlap with the first metal grid. Thus, floating metal grids are provided in all gaps of the second metal layer, which can further improve the flatness of the second metal layer.

[0019] In an optional implementation, the projections of the plurality of second floating metal grids on the first metal layer partially overlap with the first metal grid. Thus, placing floating metal grids in some gaps in the second metal layer can reduce the load on the first metal layer and improve touch performance.

[0020] In an optional implementation, the display touch module further includes: a bend portion and a lower binding area, one end of the display panel is connected to the lower binding area via the bend portion, the lower binding area is bent to the back side of the light-emitting surface of the display panel via the bend portion, and the lower binding area includes: a first metal trace, the first metal trace is electrically connected to the first metal layer and the second metal layer, and the connection point between the metal trace and the first metal layer and the second metal layer is located outside the lower binding area. Thus, the first metal trace in the lower binding area is used to replace the traces of the first metal layer and the second metal layer, and the touch integrated metal trace and the first organic layer or the second organic layer can be removed in the lower binding area, thereby avoiding etching residues of the first metal layer or the second metal layer on the first organic layer or the second organic layer, and reducing the risk of short circuits between touch signals.

[0021] In one optional implementation, the display panel includes a display area, a non-display area, and an organic clearance area and a dam located in the non-display area. The organic clearance area and the dam are spaced apart and surround the display area. In the area adjacent to the non-display area and the bend, the first metal layer and the second metal layer utilize a single-layer routing on the organic clearance area and the dam. Thus, providing a single-layer metal routing above the organic clearance area and the dam can reduce etched metal residue on the dam and the first and second metal layers above the organic clearance area in the area adjacent to the non-display area and the bend, thereby reducing the risk of short circuits.

[0022] In one optional implementation, the organic clearance region includes: a first organic clearance region, a second organic clearance region, and a third organic clearance region, sequentially arranged in a direction away from the bend portion; and the dam includes: a first dam and a second dam, the first dam being located between the first and second organic clearance regions, and the second dam being located between the second and third organic clearance regions, with the first dam being higher than the second dam. Thus, by providing a double layer of dams, the organic layer can be better confined within the display panel area.

[0023] In one optional implementation, the organic layer includes: a first organic layer, a second organic layer, and a third organic layer stacked in a direction away from the display panel; the first metal layer is disposed on a surface of the first organic layer proximal to the second organic layer, with the second organic layer covering the first metal layer; the second metal layer is disposed on a surface of the second organic layer proximal to the third organic layer, with the third organic layer covering the second metal layer. Thus, by providing three organic layers, the first and second metal layers can be encapsulated within the organic layer, resulting in a better encapsulation effect.

[0024] In an optional implementation, the display touch module further includes: an encapsulation layer, the encapsulation layer being located between the display panel and the organic layer. Thus, the display touch module adopts an organic-on-package touch integrated structure.

[0029] In an optional implementation, projections of the plurality of first floating metal grids on the second metal layer overlap with the second metal grid; and / or projections of the plurality of second floating metal grids on the first metal layer overlap with the first metal grid.

The touch-sensitive display module includes a display panel, a first organic layer disposed on the display panel, and a second organic layer disposed on the first organic layer. The touch-sensitive display module also includes a first metal layer and a second metal layer. The first metal layer is disposed within the first organic layer, and the second metal layer is disposed within the second organic layer. Compared with an inorganic encapsulation layer, the first metal layer has a better deformation capability, thereby reducing the risk of fracture of the touch-sensitive display module during large strain or deformation. The first metal layer includes a first electrode, and the second metal layer includes a second electrode. The first electrode and the second electrode are used to output a first signal when a touch operation is detected. Compared with disposing the first and second electrodes in different layers, disposing the first and second electrodes in the same layer eliminates the need for a large number of bridging micropores in the organic layer, thereby avoiding residual openings due to insufficient resolution of the organic material, thereby reducing the risk of signal disconnection due to residual openings and improving product yield. The projection of the first electrode on the second metal layer and the second electrode are alternately arranged along a first direction and a second direction, respectively, and the first direction is perpendicular to the second direction, so that the projection of the first electrode on the second metal layer and the second electrode are interlocked with each other and arranged in a checkerboard pattern, thereby reducing the driving load of the touch control module.

That is, the first metal trace in the lower binding area can be used to replace the traces of the first metal layer and the second metal layer, and there is no need to set the above-mentioned touch integrated layer in the lower binding area, thereby reducing the etching residue of the first metal layer or the second metal layer on the organic layer and reducing the risk of short circuit between touch signals.

[0033] In some embodiments, the present application further provides a display touch module, wherein the display panel of the display touch module includes: a display area, a non-display area, and an organic clearance area and a dam located in the non-display area.

[0090] In some embodiments, the first electrode 100 a is a touch driving electrode TX, and the second electrode 100 b is a touch sensing electrode RX; or, the first electrode 100 a is a touch sensing electrode RX, and the second electrode 100 b is a touch driving electrode TX.

[0091] In this embodiment, multiple touch drive electrodes TX are used to receive touch drive signals provided by a touch control module. The touch drive signals generate inductive capacitance between the multiple touch drive electrodes TX and the multiple touch sensing electrodes RX. The multiple touch sensing electrodes RX can then output corresponding electrical signals as touch sensing signals. When the capacitance between the touch drive electrodes TX and the touch sensing electrodes RX changes due to a user's touch operation, the touch sensing signals output by the touch sensing electrodes RX also change accordingly. By analyzing the specific location of the change in the sensing signal, the specific location of the touch operation can be identified.

[0092] However, in the above embodiments, the inorganic material has poor anti-bending performance. When it is used in the curved screen 10a or the flexible display panel 100210b, it is easy to cause the display panel packaging to fail and produce black spots or a black screen.

[0093] To this end, an embodiment of the present application provides an improved display module, in which an organic material is used in the upper touch integration layer of the display module instead of the inorganic material in the upper touch integration layer 1004 encapsulated in the above embodiment, so as to fully utilize the deformation ability of the organic material and reduce the risk of fracture of the display module during large strain or deformation.

[0094] Figure 7 is a cross-sectional view of a display module provided in an embodiment of the present application. As shown in Figure 7, the display module includes: a backplane 1001 stacked along the z direction, a display panel 1002, an encapsulation layer and a touch integration layer 1004 on the encapsulation. The display panel 1002 emits light to display an image in cooperation with the backplane 1001 and the encapsulation layer.

[0095] The touch integration layer 1004 on the organic package includes: an organic layer (10042a, 10042b, 10042c), a first metal layer 10043 and a second metal layer 10044, wherein the first metal layer 10043 and the second metal layer 10044 are stacked in a direction away from the display panel, and the first metal layer 10043 and the second metal layer 10044 are both located in the organic layer.

[0096] In some embodiments, the organic layer is made of organic coating (OC). For example, the material of the organic layer includes organic materials such as silicone resin and epoxy resin.

[0097] In some embodiments, the organic layer includes: a first organic layer 10042b and a second organic layer 10042c, the first organic layer 10042b is arranged on the display panel 1002, the second organic layer 10042c is arranged on the first organic layer 10042b, the first metal layer 10043 is arranged in the first organic layer 10042b, and the second metal layer 10044 is arranged in the second organic layer 10042c.

[0098] In some embodiments, the organic layer further includes: a third organic layer 10042 a , and the third organic layer 10042 is disposed between the display panel 1002 and the first organic layer 10042 b .

[0099] The structure of the encapsulation layer will be described below with reference to FIG7 . As shown in FIG7 , the encapsulation layer includes: a third organic layer 10042a, a first organic layer 10042b, and a second organic layer 10042c, which are stacked together; a first metal layer 10043 is disposed on a surface of the third organic layer 10042a close to the first organic layer 10042b, with the first organic layer 10042b covering the first metal layer 10043; and a second metal layer 10044 is disposed on a surface of the first organic layer 10042b close to the second organic layer 10042c, with the second organic layer 10042c covering the second metal layer 10044.

[0100] Therefore, the display module provided in the embodiment of the present application uses an organic material as the encapsulation layer in the touch integration layer 1004 . Compared with the solution shown in FIG4 , the encapsulation layer has better deformation capability, thereby reducing the risk of fracture of the display module during large strain or deformation.

[0101] In some embodiments of the present application, the first metal layer 10043 includes a first electrode 100a, and the second metal layer 10044 includes a second electrode 100b. The first electrode and the second electrode are used to output a first signal when a touch operation is detected.

[0102] Therefore, compared with setting the first electrode 100a and the second electrode 100b in the same layer, setting the first electrode 100a and the second electrode 100b in different layers does not require a large number of bridging micropore designs in the organic layer, thereby avoiding residual openings due to insufficient resolution of the organic material, thereby reducing the risk of signal disconnection due to residual openings and improving product yield.

[0103] The embodiment of the present application does not limit the number of the first electrode 100a and the second electrode 100b. There can be multiple first electrodes 100a and multiple second electrodes 100b. The multiple first electrodes 100a and the multiple second electrodes 100b can be arranged in an array.

[0104] In some embodiments, the smallest unit (shape of a single electrode) of the first electrode 100a and the second electrode 100b is a rhombus, the signal strength at the endpoints of the rhombus is greater than the signal strength at the edges of the rhombus, and the linear effect of the stylus is poor.

[0105] In order to further improve the touch performance of the display module, the arrangement of the first electrode 100 a and the second electrode 100 b may be adjusted to improve the linear effect of the active stylus.

[0106] In some embodiments of the present application, as shown in (a), (b), (c), and (d) in Figure 10, the projection of the first electrode 100a on the second metal layer 10044 and the second electrode 100b are arranged alternately along the first direction and the second direction, respectively, and the first direction is perpendicular to the second direction.

[0107] In some embodiments, referring to FIG. 10 , the first direction may be the X direction, and the second direction may be the Y direction, or the first direction may be the Y direction, and the second direction may be the X direction.

[0108] Thus, the projection of the first electrode 100a on the second metal layer 10044 and the second electrode 100b can be embedded with each other and arranged in a checkerboard pattern, thereby reducing the driving load of the touch control module.

[0109] In some embodiments of the present application, the first electrode 100a has a constant size along the first direction and along the second direction, and the second electrode 100b has a constant size along the first direction and along the second direction. For example, the first electrode 100a and the second electrode 100b both adopt a square pattern, so that the size of the first electrode 100a along the X direction and along the Y direction is constant, and the size of the second electrode 100b along the X direction and along the Y direction is constant.

[0110] As a result, the size of a single electrode in the first direction and the second direction remains unchanged, so that when the stylus pen moves across the screen, the signal strength is uniform at all locations, with better active pen performance and better linearity.

[0111] The arrangement of the plurality of first electrodes 100 a in the first metal layer 10043 and the plurality of second electrodes 100 b in the second metal layer 10044 will be described below with reference to FIG. 8 , FIG. 9 and FIG. 10 .

[0112] Figure 8 is a schematic diagram of the arrangement of the first electrodes. In some embodiments, the first metal layer 10043 may include multiple 2×2 repeating units as shown in (a) in Figure 8. The repeating unit includes: two first electrodes 100a, which are arranged at intervals along the X direction and the Y direction, respectively. The dimensions of the repeating unit along the X direction and the Y direction are unchanged.

[0113] Alternatively, the first metal layer 10043 may include multiple 4×4 repeating units as shown in (b) of FIG8 , wherein the repeating unit includes: 8 first electrodes 100 a , which are arranged at intervals along the X direction and the Y direction, respectively, and the dimensions of the repeating unit along the X direction and the Y direction are constant.

[0114] Alternatively, the first metal layer 10043 includes a plurality of 6×6 repeating units as shown in FIG8(c), wherein the repeating unit includes 18 first electrodes 100a, which are arranged at intervals along the X direction and the Y direction, respectively, and the size of the repeating unit along the X direction and the Y direction remains unchanged.

[0115] Alternatively, the first metal layer 10043 includes a plurality of 8×8 repeating units as shown in (d) of FIG8 , wherein the repeating unit includes 32 first electrodes 100 a , which are arranged at intervals along the X direction and the Y direction, respectively, and the dimensions of the repeating unit along the X direction and the Y direction are constant.

[0116] Figure 9 is a schematic diagram of the arrangement of the second electrode. In some embodiments, the second metal layer 10044 may include multiple 2×2 repeating units as shown in (a) in Figure 9. The repeating unit includes: two second electrodes 100b, which are arranged at intervals along the X direction and the Y direction, respectively. The dimensions of the repeating unit along the X direction and the Y direction remain unchanged.

[0117] Alternatively, it may include multiple 4×4 repeating units as shown in FIG. 9( b ), wherein the repeating unit includes eight second electrodes 100 b , which are spaced apart along the X direction and the Y direction, respectively. The size of the repeating unit along the X direction and the Y direction remains unchanged.

[0118] Alternatively, it may include multiple 6×6 repeating units as shown in FIG. 9( c ), wherein the repeating unit includes 18 second electrodes 100 b , which are spaced apart along the X direction and the Y direction, respectively. The size of the repeating unit along the X direction and the Y direction remains unchanged.

[0119] Alternatively, the repeating unit may include multiple 8×8 repeating units as shown in FIG9(d), each of which includes 32 second electrodes 100b. The repeating units have constant dimensions along the X and Y directions, are arranged at intervals along the X and Y directions, and have constant dimensions along the X and Y directions.

[0120] Figure 10 is a schematic diagram of the arrangement of the first metal layer 10043 and the second metal layer 10044. In some embodiments, as shown in (a), (b), (c), and (d) in Figure 10, multiple repeating units of the first metal layer 10043 and the second metal layer 10044 are vertically interlocked with each other to present a checkerboard distribution.

[0121] Wherein, the side length of the above-mentioned single chessboard grid is 3mm-5mm.

[0122] Therefore, in the display touch module provided by the embodiment of the present application, the projection of the first electrode 100a on the second metal layer and the second electrode 100b are interlocked with each other, presenting a checkerboard arrangement, and the size of a single electrode in the first direction and the second direction remains unchanged, so that when the stylus pen passes across the screen, the signal strength at each location is uniform, with better active pen performance and better linearity effect.

[0123] The embodiments of the present application do not limit the structures of the first electrode 100a and the second electrode 100b. In some embodiments of the present application, as shown in Figures 8 and 10, the first electrode 100a includes multiple first sub-metal wires, which form multiple metal grids. As shown in Figures 9 and 10, the second electrode 100b includes multiple second sub-metal wires, which form multiple metal grids.

[0124] In some embodiments, the metal mesh may be in the shape of a square, rectangle, diamond, or other polygonal shape. The metal meshes of the first electrode 100a and the second electrode 100b may have the same shape. For ease of distinction, the first electrode 100a and the second electrode 100b in Figures 8, 9, and 10 are illustrated with meshes of different shapes, respectively. This is for reference only and does not limit the mesh shape.

[0125] In some embodiments of the present application, the display panel includes a plurality of pixel areas arranged in a matrix, each of the metal grids corresponds to one of the pixel units, and the shape of the metal grid is the same as that of the pixel unit.

[0126] As shown in Figure 11, the plurality of first electrodes 100a extend along a third direction a, and the plurality of second electrodes 100b extend along a fourth direction b, with the third direction a being perpendicular to the fourth direction b. In some embodiments, the overlap width at an intersection A1 between the first electrode 100a and the second electrode 100b is greater than or equal to the line width of the metal mesh; and the overlap width at a non-intersection location A2 between the first electrode 100a and the second electrode 100b is less than the line width of the metal mesh.

[0127] In some embodiments, the metal mesh has a line width of 3 μm to 6 μm. This reduces the overlap between the first and second electrodes, effectively reducing the capacitance between the first and second sub-metal conductors in the vertical stacking direction, thereby further reducing the drive load of the touch control module.

[0128] In the above embodiment, the first metal layer 10043 includes a plurality of first electrodes 100 a as shown in FIG12 . The plurality of first electrodes 100 a are arranged at intervals, and there are gaps between the plurality of first electrodes 100 a , and the gaps correspond to the second electrodes.

[0129] Figure 13 is a MM cross-sectional view of the first metal layer in Figure 12. As shown in Figure 13, the first metal layer 10043 is located on the surface of the third organic layer 10042a. When preparing the first metal layer 10043, a certain amount of overetching is added to ensure that the first metal layer 10043 is completely etched in the gap positions. In this case, due to the overetching, the third organic layer 10042a is overetched to a certain depth, and a large area of ​​the third organic layer 10042a is overetched in the position where the first electrode 100a is not present. The first organic layer 10042b covers the first metal layer 10043. Due to the existence of the large-area over-etched area of ​​the third organic layer 10042a, the first organic layer 10042b above the first metal layer 10043 will flow in large quantities toward the area where the gap is located in the direction as shown by the arrow in Figure 13, so that the first organic layer 10042b between the first metal layer 10043 and the second metal layer 10044 is relatively thin as shown in Figure 14, and there is a risk of short circuit between the first metal layer 10043 and the second metal layer 10044.

[0130] To reduce the risk of short circuits between the first metal layer 10043 and the second metal layer 10044, in some embodiments, a first floating metal grid 100c may be disposed in areas of the first metal layer 10043 other than the first electrode 100a. For example, as shown in Figures 15 and 17, the first metal layer 10043 further includes a plurality of first floating metal grids 100c. These first floating metal grids 100c are spaced apart between adjacent first electrodes 100a and are insulated from each other. These first floating metal grids 100c are left suspended in the air.

[0131] In some embodiments, as shown in FIG15 , first floating metal grids 100c are disposed on the first metal layer 10043 in areas other than the first electrode 100a. Alternatively, first floating metal grids 100c may be disposed on the entire area of ​​the first metal layer 10043 other than the first electrode 100a. Projections of the plurality of first floating metal grids 100c on the second metal layer 10044 overlap with the second metal grids.

[0132] In this embodiment, the first floating metal grid 100c can be in a rhombus, rectangular, square, or other shape. The first floating metal grid 100c and the grid of the first electrode 100a can have the same structure. For ease of distinction, FIG15 illustrates the first floating metal grid 100c and the metal grid of the first electrode 100a using different shapes. This is for reference only and does not limit the grid shapes.

[0133] In some embodiments, the first floating metal grid 100 c in the first metal layer 10043 may be obtained by cutting and separating the conductive pattern of the first electrode 100 a .

[0134] Figure 16 is a cross-sectional view taken along line aa in Figure 15. As shown in Figure 16, the first floating metal grid 100c in the first metal layer 10043 reduces large-area overetching of the third organic layer 10042a and reduces the flow of the first organic layer 10042b. Therefore, the thickness h2 of the first organic layer 10042b between the first metal layer 10043 and the second metal layer 10044 is greater than the thickness h1 in Figure 14, effectively reducing the risk of shorting (micro-shorting) between the first metal layer 10043 and the second metal layer 10044 of the touch metal layer due to insufficient thickness of the first organic layer 10042b.

[0135] In other embodiments, first floating metal grids 100c are disposed in areas other than the first electrode 100a on the first metal layer 10043. This may be done by disposing first floating metal grids 100c in a portion of the first metal layer 10043 other than the first electrode 100a. As shown in FIG17 , the projections of the plurality of first floating metal grids 100c on the second metal layer 10044 partially overlap with the second metal grids.

[0136] In this embodiment, a first floating metal grid 100c is added to a portion of the first metal layer 10043 in an area other than the first electrode 100a. The area of ​​the first floating metal grid 100c can be adjusted according to actual needs and is not limited here. The area of ​​the first floating metal grid 100c only needs to be greater than 0 and smaller than the area of ​​the first floating metal grid 100c shown in FIG. 15 .

[0137] Figure 18 is a cross-sectional view taken along line bb in Figure 17. As shown in Figure 18, the first floating metal grid 100c in the first metal layer 10043 eliminates large-area overetching of the third organic layer 10042a. This prevents the flow of a large amount of the first organic layer 10042b. As a result, the thickness h3 of the first organic layer 10042b between the first metal layer 10043 and the second metal layer 10044 is greater than the thickness h1 in Figure 14. This effectively reduces the risk of shorting (micro-shorting) between the first metal layer 10043 and the second metal layer 10044 in the touch metal layer due to insufficient thickness of the first organic layer 10042b.

[0138] Furthermore, compared to Figure 16 , the overlap area between first metal layer 10043 and second metal layer 10044 in Figure 18 is reduced, resulting in lower loads on first metal layer 10043 and second metal layer 10044, and improved touch performance. Furthermore, the smaller area of ​​first floating metal grid 100c further reduces the risk of short circuits between second electrode 100b and first floating metal grid 100c.

[0139] In the above embodiment, by providing the first floating metal grid 100c in the area of ​​the first metal layer 10043 other than the first electrode 100a, the risk of shorting between the first metal layer 10043 and the second metal layer 10044 due to loss of the first organic layer 10042b is reduced. In other embodiments, to further reduce the risk of shorting, the second metal layer 10044 may be improved.

[0140] The second metal layer 10044 further includes a plurality of second floating metal grids 100d, which can be disposed in areas other than the second electrodes 100b on the second metal layer 10044. As shown in Figures 19 and 21, the second floating metal grids 100d are spaced apart between adjacent second electrodes 100b and are insulated from each other.

[0141] In some embodiments, as shown in FIG19 , second floating metal grids 100d are disposed on the second metal layer 10044 in areas other than the second electrode 100b. Alternatively, second floating metal grids 100d may be disposed on the entire area of ​​the second metal layer 10044 except the second electrode 100b. Projections of the plurality of second floating metal grids 100d on the first metal layer 10043 overlap with the first metal grids.

[0142] In this embodiment, the second floating metal grid 100d can be in a rhombus, rectangular, square, or other shape. The second floating metal grid 100d and the grid of the first electrode 100a can have the same structure. For ease of distinction, FIG19 illustrates the second floating metal grid 100d and the metal grid of the second electrode 100b using different shapes. This is for reference only and does not limit the grid shapes.

[0143] In some embodiments, the second floating metal grid 100d in the second metal layer 10044 can be obtained by cutting and separating from the conductive pattern of the second electrode 100b.

[0144] In some examples of this embodiment, a first floating metal grid 100c (not shown) may be provided on a portion of the first metal layer 10043 except the first electrode 100a. In other examples of this embodiment, as shown in FIG20 , the first floating metal grid 100c may be provided on the entire area of ​​the first metal layer 10043 except the first electrode 100a. All of these examples fall within the scope of protection of this application.

[0145] Figure 20 is a cross-sectional view taken along line cc in Figure 19. As shown in Figure 20, first floating metal grid 100c in first metal layer 10043 reduces large-area overetching of third organic layer 10042a and minimizes flow of first organic layer 10042b. Therefore, thickness h4 of first organic layer 10042b between first metal layer 10043 and second metal layer 10044 is greater than thickness h1 in Figure 14, effectively mitigating the risk of shorting (micro-shorting) between first metal layer 10043 and second metal layer 10044 due to insufficient thickness of second metal layer 10044. Furthermore, second floating metal grid 100d in second metal layer 10044 further improves the flatness above second metal layer 10044.

[0146] In the above embodiment, as shown in FIG19 , the projections of the plurality of second floating metal grids 100d on the first metal layer 10043 completely overlap with the first metal grid. In other embodiments, the second floating metal grids 100d are disposed in areas of the second metal layer 10044 excluding the second electrode 100b, or in partial areas of the second metal layer 10044 excluding the second electrode 100b. As shown in FIG21 , the projections of the plurality of second floating metal grids 100d on the first metal layer 10043 partially overlap with the first metal grid.

[0147] Referring to FIG. 21 , in addition to adding a first floating metal grid 100c to portions of first metal layer 10043, a second floating metal grid 100d is also added to portions of second metal layer 10044. The areas of first floating metal grid 100c and second floating metal grid 100d can be freely selected based on actual needs, as long as the area of ​​first floating metal grid 100c is greater than zero and smaller than the area of ​​first floating metal grid 100c shown in FIG. 15 . The area of ​​second floating metal grid 100d is greater than zero and smaller than the area of ​​second floating metal grid 100d shown in FIG. 19 .

[0148] In this embodiment, a second floating metal grid 100d is disposed on a portion of the second metal layer 10044 excluding the second electrode 100b. In some examples of this embodiment, as shown in FIG22 , a first floating metal grid 100c may be disposed on a portion of the first metal layer 10043 excluding the first electrode 100a. In other examples of this embodiment, the first floating metal grid 100c may be disposed on the entire region of the first metal layer 10043 excluding the first electrode 100a, which are not shown in the figure. All of these examples fall within the scope of protection of this application.

[0149] Figure 22 is a cross-sectional view of section dd in Figure 21. As shown in Figure 22, the first floating metal grid 100c in the first metal layer 10043 eliminates large-area overetching of the third organic layer 10042a. This prevents the flow of a large amount of the first organic layer 10042b. As a result, the thickness h5 of the first organic layer 10042b between the first metal layer 10043 and the second metal layer 10044 is greater than the thickness h1 of the first organic layer 10042b in Figure 14. This effectively reduces the risk of shorting (micro-shorting) between the first metal layer 10043 and the second metal layer 10044 in the touch metal layer due to insufficient thickness of the first organic layer 10042b.

[0150] Compared to Figure 20 , the overlap area between first metal layer 10043 and second metal layer 10044 in Figure 22 is smaller, resulting in lower loads on first metal layer 10043 and second metal layer 10044, and improved touch performance. Furthermore, the smaller areas of first and second floating metal grids 100c and 100d further reduce the risk of short circuits between second electrode 100b and first floating metal grid 100c, and between first electrode 100a and second floating metal grid 100d.

[0151] In the above embodiments, the structure of the touch integration layer of the display touch module is improved to enhance touch performance. In other embodiments, the display touch module further includes touch metal traces, which are disposed in the mechanical layer and are prone to etching residues.

[0152] To this end, embodiments of the present application also provide a display touch module to reduce etching residue on touch metal traces. As shown in Figure 23, the display touch module includes a display module 10, a bent portion 20, and a lower binding area 30. One end of the display module 10 is connected to the lower binding area 30 via the bent portion 20. The lower binding area 30 is bent by the bent portion 20 to the back side of the light-emitting surface of the display module 10.

[0153] In some embodiments, the lower bonding area includes a system-on-chip (SoC) 300, which can be bonded within the lower bonding area 30. Bonding refers to a wire bonding method used in the production and packaging of microelectronic devices. For example, metal wire (gold wire, etc.) can be used to connect the internal interconnects of the solid-state circuits in the microelectronic device using heat, pressure, or ultrasonic energy. The process can include pressure welding, wire bonding, bonding, ball bonding, and flat welding. For example, the SoC 300 is bonded within the lower bonding area 30.

[0154] In some embodiments, the display module 10 includes a display panel, an organic layer, a first metal layer 10043, and a second metal layer 10044. The first metal layer 10043 and the second metal layer 10044 are stacked in a direction away from the display panel, and both the first metal layer 10043 and the second metal layer 10044 are located within the organic layer.

[0155] In some embodiments, the display module 10 includes: a display area AA, a non-display area NA, and an organic clearance area (C3, C4, C5) and a dam (C1, C2) located in the non-display area NA. The organic clearance area (C3, C4, C5) and the dam (C1, C2) are arranged at intervals, and the organic clearance area (C3, C4, C5) and the dam (C1, C2) are all arranged around the display area AA. The first metal layer 10043 and the second metal layer 10044 need to cross the dam (C1, C2) and the organic clearance area (C3, C4, C5) in the area C adjacent to the non-display area NA and the bending portion 20 and connect to the lower binding area 30.

[0156] In some embodiments, the organic clearance area (C3, C4, C5) includes: a first organic clearance area C3, a second organic clearance area C4 and a third organic clearance area C5 arranged in sequence along the direction close to the bending portion 20, and the dam (C1, C2) includes: a first dam C1 and a second dam C2, the first dam C1 is located between the first organic clearance area C3 and the second organic clearance area C4, and the second dam C2 is located between the second organic clearance area C4 and the third organic clearance area C5.

[0157] In some embodiments, the height of the second dam C2 is higher than that of the first dam C1 , which can better confine the organic layer within the display panel area.

[0158] In some embodiments, as shown in Figures 24 and 25, above the dams (C1, C2) and organic clearance areas (C3, C4, C5) in the area C adjacent to the non-display area NA and the bending portion 20, the touch metal wiring adopts a double-layer metal design of the first metal layer 10043 + the second metal layer 10044. There is a height difference near the first dam C1 and the second dam C2 due to the organic clearance area (C3, C4, C5) of the backplane 1001, and the third organic layer 10042a and the first organic layer 10042b are stacked at the organic clearance area (C3, C4, C5) of the backplane 1001, causing the first metal layer 10043 and the second metal layer 10044 to produce etching residues at the stacking position of the third organic layer 10042a and the first organic layer 10042b. The thicker the stacking thickness of the third organic layer 10042a and the first organic layer 10042b, the more likely it is to cause etching residues of the first metal layer 10043 and the second metal layer 10044.

[0159] In some embodiments, the first metal layer 10043 and the second metal layer 10044 use single-layer routing above the dam ( C1 , C2 ) and the organic clearance area ( C3 , C4 , C5 ) in the area C adjacent to the non-display area NA and the bending portion 20 .

[0160] In some examples of this embodiment, as shown in Figures 26 and 27, the touch signal traces above the first dam C1, the second dam C2, the first organic clearance area C3, the second organic clearance area C4, and the third organic clearance area C5 are designed using a single first metal layer 10043. Using a single first metal layer 10043 for metal traces effectively avoids the risk of short circuits between touch signal lines caused by etching residues from the second metal layer 10044.

[0161] In other examples of this embodiment, as shown in Figures 28 and 29, the touch lines above the first dam C1, the second dam C2, the first organic clearance area C3, the second organic clearance area C4 and the third organic clearance area C5 adopt a single-layer second metal layer 10044 touch line design.

[0162] The display touch module provided in this embodiment can reduce the etched metal residues of the first metal layer 10043 and the second metal layer 10044 above the dam (C1, C2) and the organic clearance area (C3, C4, C5) in the area C adjacent to the non-display area NA and the bending portion 20, thereby reducing the risk of short circuit.

[0163] In some embodiments, the first metal layer 10043 and the second metal layer 10044 extend into the lower binding area 30. In the lower binding area, all touch signals use metal routing of the touch integration layer. However, the routing in the lower binding area is dense, and the metal layer is prone to metal etching residue on the surface of the third organic layer 10042a or the first organic layer 10042b, resulting in a short circuit between touch signals.

[0164] To this end, embodiments of the present application further provide a display touch module to further reduce etching residue on touch metal traces. The display touch module comprises a display module 10, a bent portion 20, and a lower binding area 30. One end of the display module 10 is connected to the lower binding area 30 via the bent portion 20. The lower binding area 30 is bent by the bent portion 20 to the back side of the light-emitting surface of the display module 10.

[0165] In some embodiments, the display module 10 includes a display panel, an organic layer, a first metal layer 10043, and a second metal layer 10044. The first metal layer 10043 and the second metal layer 10044 are stacked in a direction away from the display panel, and both the first metal layer 10043 and the second metal layer 10044 are located within the organic layer.

[0166] In some embodiments, as shown in FIG30 , lower bonding region 30 includes: a first metal trace 301, wherein first metal trace 301 is electrically connected to first metal layer 10043 and second metal layer 10044, and the connection point between first metal trace 301 and first metal layer 10043 and second metal layer 10044 is located outside lower bonding region 30. That is, within the lower bonding region, the traces of first metal layer 10043 and second metal layer 10044 can be replaced by first metal trace 301 within the lower bonding region.

[0167] For example, the first metal trace 301 can be a backplane metal trace, and the first metal trace 301 can be used to replace all or part of the first metal layer 10043 or the second metal layer 10044 trace, thereby improving the short circuit between touch signals caused by the etching residue of the touch metal trace above the organic layer in the upper touch integration technology.

[0168] In some examples of this embodiment, all touch signal traces in the lower binding area 30 are replaced by the first metal traces 301 .

[0169] In some other examples of this embodiment, part of the touch signal wiring in the lower binding area 30 is replaced by the first metal wiring 301 .

[0170] The display touch module provided in the embodiment of the present application uses a backplane metal trace 301 instead of a touch integrated metal trace in the lower binding area 30. The touch integrated metal trace and the third organic layer 10042a or the first organic layer 10042b material can be removed in the lower binding area 30, thereby avoiding etching residues of the first metal layer 10043 or the second metal layer 10044 on the third organic layer 10042a or the first organic layer 10042b material, thereby reducing the risk of short circuit between touch signals.

[0171] The present application provides a touch-sensitive display module and an electronic device. The touch-sensitive display module includes a display panel, a first organic layer disposed on the display panel, and a second organic layer disposed on the first organic layer. The touch-sensitive display module also includes a first metal layer and a second metal layer. The first metal layer is disposed within the first organic layer, and the second metal layer is disposed within the second organic layer. Compared with an inorganic encapsulation layer, the first metal layer has a better deformation capability, thereby reducing the risk of fracture of the touch-sensitive display module during large strain or deformation. The first metal layer includes a first electrode, and the second metal layer includes a second electrode. The first electrode and the second electrode are used to output a first signal when a touch operation is detected. Compared with disposing the first and second electrodes in different layers, disposing the first and second electrodes in the same layer eliminates the need for a large number of bridging micropores in the organic layer, thereby avoiding residual openings due to insufficient resolution of the organic material, thereby reducing the risk of signal disconnection due to residual openings and improving product yield. The projection of the first electrode on the second metal layer and the second electrode are arranged alternately along a first direction and a second direction, respectively. The first direction is perpendicular to the second direction, so that the projection of the first electrode on the second metal layer and the second electrode interlock with each other, forming a checkerboard arrangement, thereby reducing the driving load of the touch control module.

[0172] In some embodiments, the present application also provides a display touch module, which, compared with the above-mentioned display touch module, further includes: a bending portion and a lower binding area; one end of the display panel is connected to the lower binding area through the bending portion, and the lower binding area is bent to the back side of the light-emitting surface of the display panel through the bending portion; the first metal layer and the second metal layer are stacked in a direction away from the display panel, and the first metal layer and the second metal layer are both located in the organic layer; the lower binding area includes: a first metal trace, the first metal trace is electrically connected to the first metal layer and the second metal layer, and the connection point between the metal trace and the first metal layer and the second metal layer is located outside the lower binding area. That is, the first metal trace in the lower binding area can be used to replace the traces of the first metal layer and the second metal layer, and there is no need to set the above-mentioned touch integrated layer in the lower binding area, thereby reducing the etching residue of the first metal layer or the second metal layer on the organic layer and reducing the risk of short circuit between touch signals.

[0173] In some embodiments, the present application further provides a display touch module, wherein the display panel of the display touch module includes: a display area, a non-display area, and an organic clearance area and a dam located in the non-display area. The organic clearance area and the dam are spaced apart and both surround the display area. In the area adjacent to the non-display area and the bend, the first metal layer and the second metal layer utilize a single-layer routing on the organic clearance area and the dam. Thus, by providing a single-layer metal routing above the organic clearance area and the dam, it is possible to reduce the etched metal residue of the first metal layer and the second metal layer above the dam and the organic clearance area in the area adjacent to the non-display area and the bend, thereby reducing the risk of short circuits.

[0174] In some embodiments, the present application further provides a display touch module, wherein the first metal layer in the display touch module further includes a plurality of first floating metal grids, the first floating metal grids being spaced between adjacent first electrodes and insulated from the first electrodes. Thus, the first floating metal grids reduce the large-area overetching of the organic layer at the position of the first electrode gap, reduce the flow of the organic layer above the first metal layer into the first electrode gap, thereby reducing the loss of the organic layer between the first metal layer and the second metal layer, and reducing the risk of short circuit between the first metal layer and the second metal layer.

[0175] The display touch modules in the above aspects all fall within the protection scope of this application, and their order is not limited.

[0176] The above is only a specific embodiment of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
