Description

Technical Field

[0001] The present disclosure relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] As a new generation of mainstream display technology, micro light-emitting diodes (micro LED) are widely used in optoelectronics, microelectronics, electronic information and optics due to their high luminous efficiency, small size, low power consumption and long product life. Micro LED display technology is a display technology that uses micron-scale LEDs as light-emitting pixel units and assembles them on a drive panel to form a high-density LED array. Micro LED display panels have the advantages of high contrast, high resolution, long life, low energy consumption, fast response speed and good thermal stability. Its application can be expanded from flat panel displays to space display, wearable devices, biomedical testing and other fields. It is another display technology with the advantages of being thin and light and power-saving after organic light-emitting diodes (OLED).

[0003] With the rapid development of display technology, touch panels, as a medium for human-computer interaction, play a vital role in display technology. Existing touch solutions mainly include resistive and capacitive types, among which capacitive touch screens are more widely used. The basic principle is to use tools such as fingers or styluses to generate capacitance with the touch screen, and use the electrical signal formed by the capacitance change before and after the touch to confirm whether the panel is touched and confirm the touch coordinates.

[0004] However, the touch performance of micro LED display products in the prior art cannot be guaranteed, which in turn limits the application scope of micro LED display products. Summary of the invention

[0005] In order to solve the above technical problems, the present disclosure provides a display panel and a display device to solve the problem of poor touch performance of micro LED display devices in the prior art.

[0006] The present disclosure provides a display panel, comprising: a substrate;

[0007] A driving array layer, located on one side of the substrate;

[0008] A plurality of binding electrodes are located on a side of the driving array layer away from the substrate;

[0009] A light emitting device is located at a side of the binding electrode away from the substrate, and the light emitting device is electrically connected to the driving array layer through the binding electrode;

[0010] A touch electrode layer, the touch electrode layer being electrically connected to the touch electrode connecting wire;

[0011] In a direction perpendicular to the plane where the substrate is located, the touch electrode layer is located on a side of the binding electrode away from the substrate, and the touch electrode connecting line is located on a side of the binding electrode close to the substrate.

[0012] Based on the same inventive concept, the present disclosure also provides a display device, which includes the above-mentioned display panel.

[0013] Compared with the prior art, the technical solution provided by the embodiments of the present disclosure has the following advantages:

[0014] The display panel disclosed in the present invention includes a touch electrode layer, the touch electrode layer is electrically connected to the touch electrode connection line, and the touch electrode connection line is used to provide or receive a touch signal of the touch electrode layer, thereby realizing the touch performance of the display panel. The present invention is arranged in a direction perpendicular to the plane where the substrate is located, the touch electrode layer is located on the side of the binding electrode away from the substrate, and the touch electrode connection line is located on the side of the binding electrode close to the substrate, that is, in the direction perpendicular to the plane where the substrate is located, with the position of the binding electrode as a reference, the touch electrode connection line is located below the binding electrode, and the touch electrode layer is located above the binding electrode. The present disclosure sets the touch electrode layer for realizing the touch function on the side of the binding electrode away from the substrate, and the touch electrode connection line electrically connected to the touch electrode layer is set on the side of the binding electrode close to the substrate, such as being set in at least one conductive film layer of the driving array layer. The electrical signal driving the light-emitting device to emit light is mainly transmitted to the binding electrode through the driving array layer, thereby controlling the light-emitting device to emit light. Therefore, the touch electrode layer is higher than the binding electrode used to transmit the driving light-emitting signal, so that when the touch electrode layer realizes touch detection, the degree to which the lateral electric field between different touch electrodes is affected by the light-emitting electrical signal of the light-emitting device can be reduced as much as possible, that is, the touch detection is as unaffected by the light-emitting electrical signal as possible, which is conducive to realizing the normal light-emitting display of the display panel while improving the touch performance. The present disclosure also sets the touch electrode connection line electrically connected to the touch electrode layer to be set on the side of the binding electrode close to the substrate. Since the side of the binding electrode close to the substrate generally has multiple metal conductive layers, such as multiple metal conductive layers in the driving array layer, they can all be used to make touch electrode connection lines to lead out the touch signal of the touch electrode layer. Therefore, the conductive film layers that can be used for the touch electrode connection lines can be as many as possible, that is, the film layers where the touch electrode connection lines are located have more options, which is conducive to avoiding the setting of the touch electrode connection lines affecting the structure of the film layers of the panel itself; for example, the metal conductive film layers that need to be set up in a large area to avoid excessive IR-Drop, such as power lines, can be provided without touch electrode connection lines, but one or more other metal conductive film layers located on the side of the binding electrode close to the substrate can be selected to lead out the touch electrode connection lines. The present disclosure can ensure that the touch electrode layer is higher than the binding electrode to ensure improved touch performance, and can avoid the setting of the touch electrode connection lines affecting other arrangement structures required for the panel itself to drive, which is conducive to ensuring display quality. And if the display panel disclosed in the present disclosure is a transparent display panel, the touch electrode connection lines can also be selectively set in multiple film layers on the side of the binding electrode close to the substrate to minimize the area of ​​the circuit impermeable area of ​​the metal layer, which is conducive to improving the transparent display effect.

[0044] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0046] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of a planar structure of a display panel provided by an embodiment of the present invention, Figure 2 yes Figure 1 A schematic cross-sectional structure diagram along the A-A' line, the display panel 000 provided in this embodiment includes:

[0047] Substrate 10;

[0048] The driving array layer 20 is located on one side of the substrate 10;

[0049] A plurality of binding electrodes 30 are located on a side of the driving array layer 20 away from the substrate 10;

[0050] The light emitting device 40 is located at a side of the binding electrode 30 away from the substrate 10 , and the light emitting device 40 is electrically connected to the driving array layer 20 through the binding electrode 30 ;

[0051] A touch electrode layer 50 , the touch electrode layer 50 is electrically connected to a touch electrode connection line 60 ;

[0052] In a direction Z perpendicular to the plane of the substrate 10 , the touch electrode layer 50 is located on a side of the binding electrode 30 away from the substrate 10 , and the touch electrode connecting line 60 is located on a side of the binding electrode 30 close to the substrate 10 .

[0053] Specifically, the display panel 000 provided in this embodiment can be a sub-millimeter light-emitting diode (mini LED) or a micro light-emitting diode (micro LED) display panel. The film layer structure of the display panel 000 includes a substrate 10. The substrate 10 can be used as a carrier substrate of the display panel 000, and is used to make and set the remaining structures of the display panel 000 on the substrate 10, such as the film layer structure used to make the drive array layer 20, the binding electrode 30 and the light-emitting device 40 located on one side of the substrate 10 in this embodiment. It can be understood that the drive array layer 20 in this embodiment can include a structure of multiple conductive film layers and multiple insulating layers. The drive array layer 20 can be understood as a film layer for making a drive circuit structure that drives the light-emitting device 40 to emit light, such as Figure 2 As shown, the drive array layer 20 can be made into a circuit structure such as a thin film transistor 20T that drives the light-emitting device 40 to emit light. The source or drain of the thin film transistor 20T can be electrically connected to the anode pin 401 of the light-emitting device 40 through the binding electrode 30, and the cathode pin 402 of the light-emitting device 40 can be electrically connected to the cathode signal line (not shown in the figure) in the display panel 000 through the binding electrode 30. The drive array layer 20 can also include a plurality of conductive signal lines (such as scanning signal lines, data signal lines, power signal lines, etc.) to achieve the transmission of driving signals to each light-emitting device 40 and drive the light-emitting device 40 to achieve normal light-emitting display effects.

[0054] The light-emitting device 40 of this embodiment can be a light-emitting device such as a micro LED or a mini LED. During specific implementation, the light-emitting device 40 can be transferred to a substrate on which a film layer such as a drive array layer 20 has been completed by mass transfer technology, so that the anode pin 401 and the cathode pin 402 of the light-emitting device 40 are respectively electrically connected to the binding electrode 30 on the substrate, thereby realizing the driving circuit structure of the drive array layer 20 to drive the light-emitting device 40 to emit light and realize the display function.

[0055] Optionally, the light emitting device 40 in the display panel 000 of this embodiment may be packaged in a horizontal light emitting chip. In specific implementation, the light emitting device 40 may also be packaged in a vertical light emitting chip, which is not limited in this embodiment.

[0056] Optionally, a conductive structure such as solder or eutectic layer (not shown in the figure) may be provided between the binding electrode 30 and the anode pin 401 and cathode pin 402 of the light emitting device 40. When the light emitting device 40 is transferred, the cathode pin 402 and anode pin 401 of the light emitting device 40 may be aligned with the binding electrode 30 on the display substrate by a micro-stamp, and the conductive structure such as solder or eutectic layer may be pressed by the downward pressing action of the micro-stamp, thereby achieving the bonding electrical connection between the light emitting device 40 and the binding electrode 30. It is understandable that the eutectic layer may be made of a high melting point eutectic material, such as a eutectic material of solder and silver or gold.

[0057] The display panel 000 of this embodiment includes a plurality of light emitting devices 40. The region where at least one light emitting device 40 is located can be understood as a pixel region divided by the display panel 000. It can be understood that Figure 1 The arrangement of the plurality of light emitting devices 40 in an array is merely used as an example for illustration. In a specific implementation, the arrangement of the plurality of light emitting devices 40 in the display panel 000 includes but is not limited to this.

[0058] The display panel 000 of this embodiment further includes a touch electrode layer 50, and the touch electrode layer 50 is electrically connected to the touch electrode connection line 60, and the touch electrode connection line 60 is used to provide or receive a touch signal of the touch electrode layer 50, thereby realizing the touch performance of the display panel 000. It can be understood that the configuration structure of the touch electrode layer 50 and the configuration structure of the touch electrode connection line 60 are not described in detail in this embodiment, and the details can be understood by referring to the subsequent embodiments.

[0059] In order to realize the touch function in the related art, it is necessary to set a metal conductive layer to lead out the touch signal of the touch electrode layer. For example, in the related art, the touch electrode is set in the film layer where the binding electrode is located, which makes it easy for the touch signal to be affected by the light-emitting signal of the light-emitting device, which is not conducive to improving the touch accuracy. In addition, in the related art, the touch electrode is set in the film layer where the binding electrode is located, and then the touch signal of the touch electrode is led out through an additional metal layer. The additional metal layer needs to lead out the touch signal of the touch electrode and also needs to serve as the conductive structure required for the panel itself to drive, such as the power line. Therefore, when the additional metal layer is used to lead out the touch signal, the occupied area of ​​the metal layer is very tight; and because the metal layer is an opaque material, if the metal layer not only makes the conductive structure required to drive the panel itself, but also serves as the touch electrode connection line for leading out the touch signal, the area of ​​the circuit opaque area of ​​the metal layer will become larger, and if the area of ​​the conductive structure required for the panel itself to drive, such as the power line, is reduced to make room for leading out the touch electrode connection line, the power line area will be too small, resulting in too large IR-Drop, which is not conducive to ensuring the display quality. In the related art, a touch electrode is arranged on the film layer where the binding electrode is located, and then a touch signal of the touch electrode is led out through an additional metal layer, which results in a complex process and high cost.

[0060] In order to solve the above problems, the present embodiment is arranged in the direction Z perpendicular to the plane where the substrate 10 is located, the touch electrode layer 50 is located on the side of the binding electrode 30 away from the substrate 10, and the touch electrode connection line 60 is located on the side of the binding electrode 30 close to the substrate 10, that is, in the direction Z perpendicular to the plane where the substrate 10 is located, with the position of the binding electrode 30 as a reference, the touch electrode connection line 60 is located below the binding electrode 30, and the touch electrode layer 50 is located above the binding electrode 30. In the prior art, when touch detection is performed between touch electrodes, the lateral detection electric field is easily blocked by the light-emitting device bound to the binding electrode, so the lateral electric field generated invisibly between the touch electrodes is easily affected by the light-emitting device, which affects the touch performance of the display panel and is not conducive to improving the touch accuracy.

[0061] In this embodiment, the touch electrode layer 50 for realizing the touch function is arranged on the side of the binding electrode 30 away from the substrate 10, and the touch electrode connecting line 60 electrically connected to the touch electrode layer 50 is arranged on the side of the binding electrode 30 close to the substrate 10, such as being arranged in at least one conductive film layer of the driving array layer 20. The electrical signal for driving the light-emitting device 40 to emit light is mainly transmitted to the binding electrode 30 through the driving array layer 20, thereby controlling the light-emitting device 40 to emit light. Therefore, the touch electrode layer 50 is higher than the binding electrode 30 for transmitting the driving light-emitting signal. When the touch electrode layer 50 realizes touch detection, the degree to which the lateral electric field between different touch electrodes is affected by the light-emitting electrical signal of the light-emitting device 40 can be reduced as much as possible, that is, the touch detection is not affected by the light-emitting electrical signal as much as possible, which is conducive to realizing the normal light-emitting display of the display panel 000 while improving the touch performance.

[0062] It should be noted that the figure of this embodiment only illustrates the structure of the display panel by way of example. In specific implementation, the structure of the display panel includes but is not limited to this, and may also include other structures that can realize the display function. For details, please refer to the structure of the mini LED or micro LED display panel in the related technology for understanding, and this embodiment will not be elaborated here.

[0063] Optional, please continue to refer to Figure 1 and Figure 2 In this embodiment, in the direction Z perpendicular to the plane where the substrate 10 is located, the distance H1 from the touch electrode layer 50 to the substrate 10 is greater than the distance H2 from the binding electrode 30 to the substrate 10, and the distance H2 from the binding electrode 30 to the substrate 10 is greater than the distance H3 from the touch electrode connecting line 60 to the substrate 10.

[0064] In this embodiment, the touch electrode layer 50 that realizes the touch function is arranged on the side of the binding electrode 30 away from the substrate 10, and the touch electrode connection line 60 electrically connected to the touch electrode layer 50 is arranged on the side of the binding electrode 30 close to the substrate 10. The touch electrode connection line 60 can be arranged in a conductive film layer of the drive array layer 20 between the substrate 10 and the binding electrode 30, and is used to provide a touch drive signal for the touch electrode layer 50. In the direction Z perpendicular to the plane where the substrate 10 is located, the distance relationship between the touch electrode layer 50, the binding electrode 30, the touch electrode connecting line 60 and the substrate 10 is that the distance H1 from the touch electrode layer 50 to the substrate 10 is greater than the distance H2 from the binding electrode 30 to the substrate 10, and the distance H2 from the binding electrode 30 to the substrate 10 is greater than the distance H3 from the touch electrode connecting line 60 to the substrate 10, thereby ensuring that the touch electrode layer 50 is on the side of the binding electrode 30 away from the substrate 10, and the touch electrode connecting line 60 electrically connected to the touch electrode layer 50 is on the side of the binding electrode 30 close to the substrate 10, thereby avoiding the lateral electric field between the touch detection signals of the touch electrode layer 50 from being affected by the light-emitting electrical signals of the light-emitting device 40, which is beneficial to improving the touch performance. In addition, the present embodiment further provides a touch electrode connection line 60 electrically connected to the touch electrode layer 50, which is arranged on the side of the binding electrode 30 close to the substrate 10. Since the side of the binding electrode 30 close to the substrate 10 generally has multiple metal conductive layers, such as multiple metal conductive layers in the drive array layer 20, all of which can be used to make the touch electrode connection line 60 to lead out the touch signal of the touch electrode layer 50. Therefore, the touch electrode connection line 60 can use as many conductive film layers as possible, that is, the film layer where the touch electrode connection line 60 is located has more selectivity, which is conducive to avoiding the setting of the touch electrode connection line 60 affecting the structure of the film layer of the panel itself. For example, the metal conductive film layer that needs to be set up in a large area to avoid excessive IR-Drop, such as the power line, can be provided without the touch electrode connection line 60, and instead one or more other metal conductive film layers with more spare space located on the side of the binding electrode 30 close to the substrate 10 are selected to lead out the touch electrode connection line 60.

[0065] In this embodiment, the touch electrode layer 50 for realizing the touch function is arranged on the side of the binding electrode 30 away from the substrate 10, and the touch electrode connection line 60 electrically connected to the touch electrode layer 50 is arranged on the side of the binding electrode 30 close to the substrate 10, which can ensure that the touch electrode layer 50 is higher than the binding electrode 30 to ensure improved touch performance, and can also avoid the setting of the touch electrode connection line 60 affecting other arrangement structures required for the panel itself to drive, which is conducive to ensuring display quality. And if the display panel 000 of this embodiment is a transparent display panel, the touch electrode connection line 60 can also be selectively arranged in multiple film layers on the side of the binding electrode 30 close to the substrate 10 to minimize the area of ​​the circuit impermeable area of ​​the metal layer, which is conducive to improving the transparent display effect. It can be understood that the distance H1 from the touch electrode layer 50 to the substrate 10, the distance H2 from the binding electrode 30 to the substrate 10, and the distance H3 from the touch electrode connecting line 60 to the substrate 10 in this embodiment are all illustrated as the distance between the surface of the structure away from the substrate 10 and the upper surface of the substrate 10. In specific implementation, the distance from a certain structure to the substrate 10 can also be understood as the distance between the surface of the structure facing the substrate 10 and the lower surface of the substrate 10, which is not limited in this embodiment.

[0066] In some optional embodiments, please refer to Figure 1 and Figure 3 , Figure 3 yes Figure 1 Another schematic diagram of the cross-sectional structure along the A-A' direction, in this embodiment, along the direction Z perpendicular to the plane where the substrate 10 is located, the distance from the surface of the touch electrode layer 50 facing the substrate 10 to the substrate 10 is a first distance H4, and the distance from the surface of the light-emitting device 40 away from the substrate 10 to the substrate 10 is a second distance H5; wherein the first distance H4 is greater than or equal to the second distance H5.

[0067] This embodiment explains that when the touch electrode layer 50 realizing the touch function is arranged on the side of the binding electrode 30 away from the substrate 10, and the touch electrode connection line 60 electrically connected to the touch electrode layer 50 is arranged on the side of the binding electrode 30 close to the substrate 10, the height of the touch electrode layer 50 needs to satisfy the following conditions: along the direction Z perpendicular to the plane where the substrate 10 is located, the distance from the surface of the touch electrode layer 50 facing the substrate 10 to the substrate 10 is a first distance H4, and the distance from the surface of the light emitting device 40 away from the substrate 10 to the substrate 10 is a second distance H5; wherein the first distance H4 is greater than or equal to the second distance H5. The first distance H4 is greater than or equal to the second distance H5, which can ensure that the touch electrode layer 50 is higher than the light emitting device 40, effectively ensuring that the lateral electric field between the touch detection signals of the touch electrode layer 50 will not be affected by the light emitting electrical signals of the light emitting device 40, thereby improving the touch performance. Optionally, the first distance H4 is equal to the second distance H5, that is, the lower surface of the touch electrode layer 50 is flush with the upper surface of the light-emitting device 40. This can avoid the light-emitting side of the subsequent packaging rear panel (the side of the light-emitting device 40 away from the substrate 10) being uneven, affecting the propagation of the light path of the light-emitting device 40, which is beneficial to improving the display quality.

[0068] In some optional embodiments, please continue to refer to Figure 1-Figure 3 In this embodiment, the display panel 000 further includes a raised portion 70 ( Figure 2 and Figure 3 In the direction Z perpendicular to the plane where the substrate 10 is located, the raised portion 70 is located between the touch electrode layer 50 and the binding electrode 30 , and the raised portion 70 does not overlap with the light-emitting device 40 .

[0069] This embodiment explains that in order to realize that in the direction Z perpendicular to the plane where the substrate 10 is located, the touch electrode layer 50 is located on the side of the binding electrode 30 away from the substrate 10, and the touch electrode connection line 60 is located on the side of the binding electrode 30 close to the substrate 10, that is, in the direction Z perpendicular to the plane where the substrate 10 is located, based on the position of the binding electrode 30, the touch electrode connection line 60 is located below the binding electrode 30, and the touch electrode layer 50 is located above the binding electrode 30, a padding portion 70 may be provided between the touch electrode layer 50 and the binding electrode 30, and the padding portion 70 is used to pad the touch electrode layer 50. In the direction Z perpendicular to the plane where the substrate 10 is located, the padding portion 70 does not overlap with the light emitting device 40, so that the setting of the padding portion 70 can avoid affecting the binding electrical connection effect between the light emitting device 40 and the binding electrode 30. The setting of the padding portion 70 in this embodiment allows the touch electrode layer 50 to be raised. Optionally, the lower surface of the touch electrode layer 50 is not lower than the upper surface of the light-emitting device 40. The lateral electric field of different touch electrodes in the touch electrode layer 50 when implementing touch detection will not be interfered by the electrical signal of the light-emitting device 40, thereby effectively improving the touch performance. In addition, since the lower surface of the touch electrode layer 50 is not lower than the upper surface of the light-emitting device 40, the touch electrode layer 50 can be closer to the touch subject (such as detecting a finger or a stylus, etc.) when the display panel 000 performs touch detection, and the vertical distance between the touch electrode layer 50 and the touch subject can be reduced, thereby effectively improving the touch accuracy.

[0070] It is understandable that the padding portion 70 of this embodiment can be made of an organic film. The padding portion 70 of the organic film material can not only play the role of padding the touch electrode layer 50 to be made later, but also play the role of protecting and flattening the surface of the drive array layer 20, which is conducive to subsequent packaging. When the display panel 000 is manufactured, the light-emitting device 40 can be transferred by the giant transfer bonding process after the binding electrode 30 is manufactured, and then the padding portion 70 is manufactured to ensure that the touch electrode layer 50 to be manufactured later is located on the side of the binding electrode 30 away from the substrate 10, and the manufacturing is more convenient. Or in some other optional processes, after the binding electrode 30 is manufactured, the padding layer can be manufactured and then the padding portion 70 between the binding electrodes 30 can be patterned, so that the gap between the padding portions 70 can expose the space of the light-emitting device 40, and then the touch electrode layer 50 is manufactured or the light-emitting device 40 is transferred by the giant transfer bonding process. This embodiment does not limit the process technology. When it is implemented, it can be selected according to actual needs.

[0071] Optionally, the organic film selected for the raised portion 70 in the present embodiment may be a transparent organic film, thereby enabling the display panel 000 of the present embodiment to be a transparent display panel. Since the material used to make the touch electrode layer 50 is generally a transparent conductive material, the area where the touch electrode layer 50 is located can be understood as the light-transmitting area of ​​the transparent display panel, and the area where the light-emitting device 40 is located can be understood as the light-emitting area of ​​the transparent display panel, thereby achieving the display effect of the transparent display panel.

[0072] Optional, such as Figure 4-Figure 5 As shown, Figure 4 is another schematic diagram of a planar structure of a display panel provided by an embodiment of the present invention, Figure 5 yes Figure 4 A schematic diagram of a cross-sectional structure taken along the BB' direction, the touch electrode layer 50 of the present embodiment includes a plurality of touch electrode blocks 501, in the direction Z perpendicular to the plane where the substrate 10 is located, the touch electrode blocks 501 correspond to the elevated portions 70 one by one, and a gap 70K is included between the elevated portions 70 corresponding to two adjacent touch electrode blocks 501; the orthographic projection of the touch electrode block 501 on the substrate 10 is located within the orthographic projection range of the elevated portion 70 on the substrate 10.

[0073] This embodiment explains that the raising portion 70 for raising the touch electrode layer 50 can be in blocks. If the touch electrode layer 50 includes N touch electrode blocks 501, the raising portion 70 also includes N blocks. There is a gap 70K between the raising portions 70 corresponding to two adjacent touch electrode blocks 501, forming a one-to-one arrangement of the touch electrode blocks 501 and the raising portions 70, thereby ensuring that each touch electrode block 501 is raised by the raising portion 70, and further ensuring that the touch electrode blocks 501 of the touch electrode layer 50 above the raising portion 70 are higher than the binding electrodes 30, and the touch detection signal will not be affected by the electrical signal of the light-emitting device 40 as much as possible.

[0074] Optionally, in this embodiment, the thickness of the raised portion 70 adjacent to the light emitting devices 40 of different colors may be different. Since the light emitting devices 40 of different colors have different heights in the direction Z perpendicular to the plane where the substrate 10 is located due to differences in their own processes, the raised portions 70 are manufactured independently, and the raised portions 70 corresponding to the light emitting devices 70 with a high height in the direction Z perpendicular to the plane where the substrate 10 is located may be thick, and the raised portions 70 corresponding to the light emitting devices 70 with a short height may be thin, thereby ensuring that the touch electrode block 501 of the touch electrode layer 50 above the raised portion 70 is higher than the binding electrode 30, and the touch detection signal will not be affected by the electrical signal of the light emitting device 40.

[0075] It can be understood that the present embodiment does not limit the area of ​​the raised portion 70 , and it is only necessary that the orthographic projection of the touch electrode block 501 on the substrate 10 is located within the orthographic projection range of the raised portion 70 on the substrate 10 , that is, the touch electrode block 501 corresponds to the raised portion 70 one-to-one, and the area of ​​the raised portion 70 is slightly larger than or equal to that of the touch electrode block 501 , and can support the touch electrode block 501 .

[0076] In some optional embodiments, please refer to Figure 6 and Figure 7 , Figure 6 is another schematic diagram of a planar structure of a display panel provided by an embodiment of the present invention, Figure 7 yes Figure 6 A schematic cross-sectional structure diagram along the CC' direction shows that the touch electrode layer 50 of this embodiment includes a plurality of touch electrode blocks 501 . In the direction Z perpendicular to the plane where the substrate 10 is located, one pad 70 corresponds to at least two different touch electrode blocks 501 .

[0077] This embodiment explains that if the touch electrode layer 50 includes N touch electrode blocks 501, then in the direction Z perpendicular to the plane where the substrate 10 is located, one raised portion 70 corresponds to at least two, that is, the raised portion 70 can be filled as a whole between adjacent light-emitting devices 40, which can ensure that the touch electrode blocks 501 of the touch electrode layer 50 above the raised portion 70 are higher than the binding electrodes 30, thereby improving the process efficiency and allowing the raised portion 70 of the entire layer to protect the light-emitting devices 70.

[0078] It is understandable that when the padding portion 70 in this embodiment is a whole layer filled between adjacent light-emitting devices 40, the process of the padding portion 70 can be made after the light-emitting device 40 is bound and electrically connected to the binding electrode 30, and the process is more convenient. The padding portion 70 is filled as a whole between adjacent light-emitting devices 40, and the padding portion 70 can be made of an organic film material. The padding portion 70 of the organic film material can not only play a role in padding the touch electrode layer 50 to be made later, but also play a role in protecting and flattening the surface of the drive array layer 20, which is beneficial to subsequent packaging.

[0079] It is understandable that when the raised portion 70 in this embodiment is a whole layer filled between adjacent light-emitting devices 40 , the material of the raised portion 70 can be a transparent organic film material, thereby preventing the filling of the raised portion 70 from affecting the light-emitting effect of the light-emitting device 40 .

[0080] It should be noted that, in this embodiment, the touch electrode layer 50 includes multiple touch electrode blocks 501. The touch electrode block 501 can be understood as an electrode block that provides a driving signal, or as an electrode block that receives a sensing signal, or the touch electrode block 501 is an electrode block in a touch unit that provides a driving signal, or can be understood as an electrode block in a touch unit that receives a sensing signal. This embodiment does not limit this.

[0081] In some optional embodiments, please refer to Figure 8 and Fig. 9 , Figure 8 is another schematic diagram of a planar structure of a display panel provided by an embodiment of the present invention, Fig. 9 yes Figure 8 A schematic diagram of the connection structure of the touch electrode layer and the touch electrode connection line in the middle area. In this embodiment, the touch electrode layer 50 includes a plurality of touch units 50A, and the touch electrode connection line 60 includes a touch unit connection line 60A;

[0082] Along a direction parallel to the plane where the substrate 10 is located, two adjacent touch control units 50A are electrically connected through a touch control unit connecting line 60A.

[0083] This embodiment explains that when the touch electrode layer 50 is used to make a structure that realizes the touch detection function, the touch electrode layer 50 can be set to include a plurality of touch units 50A, and the touch electrode connection lines 60 electrically connected to the touch units 50A are touch unit connection lines 60A. The touch unit connection lines 60A are used to electrically connect adjacent touch units 50A in a direction parallel to the plane where the substrate 10 is located.

[0084] Optional, such as Figure 8 and Fig. 9 As shown, the touch control units 50A included in the touch control electrode layer 50 may include a plurality of touch control receiving units 50A1 for receiving touch sensing signals and a plurality of touch control transmitting units 50A2 for transmitting touch driving signals; it can be understood that, in order to clearly illustrate the structure of this embodiment, Figure 8 and Fig. 9 Different filling patterns are used to distinguish the receiving touch control unit 50A1 and the transmitting touch control unit 50A2.

[0085] A plurality of receiving touch control units 50A1 are arranged along the first direction X to form a receiving unit row 50A1H, and a plurality of receiving unit rows 50A1H are arranged in sequence along the second direction Y;

[0086] A plurality of transmitting touch control units 50A2 are arranged along the second direction Y to form a transmitting unit column 50A2L, and a plurality of transmitting unit columns 50A2L are arranged in sequence along the first direction X; wherein the first direction X and the second direction Y intersect in a direction parallel to the plane where the substrate 10 is located; it can be understood that this embodiment is illustrated by taking the first direction X and the second direction Y being perpendicular to each other in a direction parallel to the plane where the substrate 10 is located as an example.

[0087] The touch unit connection lines 60A include a first connection line 60A1 and a second connection line 60A2. Along the first direction X, two adjacent receiving touch units 50A1 are electrically connected through the first connection line 60A1; along the second direction Y, two adjacent transmitting touch units 50A2 are electrically connected through the second connection line 60A2.

[0088] This embodiment explains that the arrangement of the touch control unit 50A of the touch control electrode layer 50 can be that a plurality of receiving touch control units 50A1 are arranged along the first direction X to form a receiving unit row 50A1H, a plurality of transmitting touch control units 50A2 are arranged along the second direction Y to form a transmitting unit column 50A2L, a plurality of receiving unit rows 50A1H are arranged in sequence along the second direction Y, and a plurality of transmitting unit columns 50A2L are arranged in sequence along the first direction X; the receiving unit rows 50A1H and the transmitting unit columns 50A2L are crossed and insulated from each other, and when performing touch detection , a touch driving signal is input to the multiple transmitting touch units 50A2 in the transmitting unit column 50A2L through the second connecting line 60A2, and the touch sensing signals of the multiple receiving touch units 50A1 in the receiving unit row 50A1H are received and detected through the first connecting line 60A1. When the touch subject touches the display panel 000, the sensing signal on the receiving touch unit 50A1 at the touch position changes, and the touch position can be determined according to the touch sensing signal received and detected by the first connecting line 60A1, thereby achieving a touch detection effect.

[0089] It can be understood that Figure 8 In the example, the overall shapes of the multiple receiving touch units 50A1 (the dotted box represents one receiving touch unit 50A1) and the multiple transmitting touch units 50A2 (the dotted box represents one transmitting touch unit 50A2) included in the multiple touch units 50A are all rhombuses. In specific implementation, the overall shape of a single touch unit 50A can be other shapes, such as a square, etc., which is not limited in this embodiment. The overall shape of the single touch unit 50A mentioned in this embodiment can be understood as the shape of the positive projection of the single touch unit 50A on the plane where the substrate 10 is located, and the overall shape can be expressed as the shape formed by the approximate outer contour of the positive projection of the single touch unit 50A on the plane where the substrate 10 is located, which does not mean that the overall shape of the single touch unit 50A is a standard rhombus.

[0090] In this embodiment, the outer contour of the orthographic projection of a single touch unit 50A on the plane where the substrate 10 is located is roughly rhombus-shaped, so that the edge of the receiving touch unit 50A1 and the edge of the transmitting touch unit 50A2 can be as close as possible, and the distance between them can be small, which can improve the touch detection accuracy.

[0091] Optionally, in this embodiment, the first connecting line 60A1 and the second connecting line 60A2 are arranged in different layers ( Figure 8 In the figure, the first connecting line 60A1 and the second connecting line 60A2 are indicated by different thicknesses, so that the receiving unit row 50A1H formed by the first connecting line 60A1 electrically connecting the receiving touch unit 50A1 and the transmitting unit column 50A2L formed by the second connecting line 60A2 electrically connecting the transmitting touch unit 50A2 cross and are insulated from each other, thereby avoiding mutual interference between the touch sensing signal and the touch driving signal, so as to improve the touch performance.

[0092] Optional, such as Figure 8 and Fig. 9 As shown, the touch control unit 50A in this embodiment includes n 2 +(n+1) 2 touch electrode blocks 501, wherein n is a positive integer; the touch electrode connection line 60 further includes a touch electrode block connection line 60B;

[0093] Along a direction parallel to the plane where the substrate 10 is located, two adjacent touch electrode blocks 501 in the touch control unit 50A are electrically connected through a touch electrode block connecting line 60B.

[0094] This embodiment explains that a single touch unit 50A may include a plurality of electrically connected touch electrode blocks 501, and through the arrangement of the plurality of touch electrode blocks 501, the outer contour of the orthographic projection of the single touch unit 50A on the plane where the substrate 10 is located is roughly a rhombus. Figure 8 and Fig. 9 As shown, the touch control unit 50A in this embodiment includes n 2 +(n+1) 2 When n is a positive integer 1, the touch control unit 50A includes five touch control electrode blocks 501, and the five touch control electrode blocks 501 are divided into multiple rows and columns (such as Figure 8 and Fig. 9 In the embodiment, there are 3 rows and 3 columns in the middle row, 3 touch electrode blocks 501 in the two side rows, 3 touch electrode blocks 501 in the middle column, and 1 touch electrode blocks 501 in the two side columns), so that the shape of a single touch unit 50A composed of five touch electrode blocks 501 is a cross. The area of ​​the touch unit 50A itself is very small, and the overall shape of the single touch unit 50A is a rhombus in a microscopic view.

[0095] Understandably, Figure 8 and Fig. 9 The touch control unit 50A shown includes n 2 +(n+1) 2 touch electrode blocks 501, n is a positive integer 1. In some other optional embodiments, the touch unit 50A includes n touch electrode blocks 501, n is a positive integer 1. 2 +(n+1) 2 touch electrode blocks 501, n can also be other positive integers. Fig.10 and Fig.11 As shown, Fig.10 is another schematic diagram of a planar structure of a display panel provided by an embodiment of the present invention, Fig.11 yes Fig.10 A schematic diagram of the connection structure of the touch electrode layer and the touch electrode connection line in the middle part of the region. The touch unit 50A in this embodiment includes n 2 +(n+1) 2 When n is a positive integer 2, the touch control unit 50A includes thirteen touch control electrode blocks 501, and the thirteen touch control electrode blocks 501 are divided into multiple rows and columns (such as Fig.10 and Fig.11 There are 5 rows and 5 columns in the middle row, and the number of touch electrode blocks 501 in the rows on both sides of the middle row is 5, the number of touch electrode blocks 501 in the rows on both sides of the middle row is 3, the number of touch electrode blocks 501 in the rows on both sides of the middle row is 1, the number of touch electrode blocks 501 in the middle column is 5, the number of touch electrode blocks 501 in the columns on both sides of the middle column is 3, and the number of touch electrode blocks 501 in the columns on both sides of the middle column is 1), so that the shape of a single touch unit 50A composed of thirteen touch electrode blocks 501 is a cross. The area of ​​the touch unit 50A itself is very small, and the overall shape of the single touch unit 50A is a rhombus in a microscopic view.

[0096] As can be seen from the above, in this embodiment, the touch control unit 50A includes n 2 +(n+1) 2 touch electrode blocks 501, n is a positive integer, in order to make the shape of a single touch unit 50A have an overall diamond shape in a microscopic view, the touch unit 50A may include n touch electrode blocks 501, n is a positive integer, and ... 2 +(n+1) 2 The touch electrode blocks 501 are arranged in a cross shape with multiple rows and columns. No matter what value n takes, it is satisfied that along the second direction Y, the touch unit 50A includes multiple touch electrode block rows 501H, and the (n+1)th touch electrode block row 501H includes (2n+1) touch electrode blocks 501; Fig.12 As shown, Fig.12 yes Figure 8In the structural schematic diagram of the touch control unit, n is 1, then in the touch control unit 50A composed of five touch electrode blocks 501, along the second direction Y, the touch control unit 50A includes three touch electrode block rows 501H, and the second touch electrode block row 501H includes three touch electrode blocks 501; and / or, along the first direction X, the touch control unit 50A includes a plurality of touch electrode block columns 501L, and the (n+1)th touch electrode block column 501L includes (2n+1) touch electrode blocks 501; if n is 1, then in the touch control unit 50A composed of five touch electrode blocks 501, along the first direction X, the touch control unit 50A includes three touch electrode block columns 501L, and the second touch electrode block column 501L includes three touch electrode blocks 501. The first direction X and the second direction Y intersect in a direction parallel to the plane where the substrate 10 is located. This embodiment is described by taking the example that the first direction X and the second direction Y are perpendicular to each other in a direction parallel to the plane where the substrate 10 is located.

[0097] Optionally, in this embodiment, the touch control unit 50A includes n 2 +(n+1) 2 touch electrode blocks 501, n is a positive integer, in order to make the shape of a single touch unit 50A have an overall diamond shape in a microscopic view, the touch unit 50A may include n touch electrode blocks 501, n is a positive integer, and ... 2 +(n+1) 2 The touch electrode blocks 501 are arranged in a cross shape with multiple rows and columns. No matter what value n takes, it is satisfied that in the second direction Y, in a touch unit 40A, the number of touch electrode blocks 501 included in the (n+1)th touch electrode block row 50H is greater than the number of touch electrode blocks 501 included in other touch electrode block rows; Fig.12 As shown, n is 1, then in the touch control unit 50A composed of five touch electrode blocks 501, along the second direction Y, the touch control unit 50A includes three touch electrode block rows 501H, the second touch electrode block row 501H includes three touch electrode blocks 501, and the remaining touch electrode block rows 501H all include one touch electrode block 501; and / or, in the first direction X, in a touch control unit 50A, the (n+1)th touch electrode block column 501L The number of touch electrode blocks 501 included is greater than the number of touch electrode blocks 501 included in other touch electrode block columns 501L; if n is 1, then in the touch control unit 50A composed of five touch electrode blocks 501, along the first direction X, the touch control unit 50A includes three touch electrode block columns 501L, the second touch electrode block column 501L includes three touch electrode blocks 501, and the remaining touch electrode block columns 501L each include one touch electrode block 501. Or, Fig.13 As shown, Fig.13 yes Fig.10The structural diagram of the touch control unit in FIG. 5A also satisfies the above arrangement structure when n is 2, and this embodiment will not be described in detail here. The arrangement of the touch electrode block 501 in the above touch control unit 50A is also applicable when n is other positive integers, so that the shape of the single touch control unit 50A can be a diamond shape in the microscopic view.

[0098] Please refer to Figure 8-Figure 13 The touch control unit 50A of this embodiment includes n 2 +(n+1) 2 When a single touch control unit 50A includes multiple touch control electrode blocks 501, the touch control electrode connection line 60 also includes a touch control electrode block connection line 60B, and the touch control electrode block connection line 60B is used to electrically connect the touch electrode blocks 501 in the same touch control unit 50A. Fig.12 and Fig.13 As shown, along a direction parallel to the plane of the substrate 10 , two adjacent touch electrode blocks 501 in the touch unit 50A are electrically connected through a touch electrode block connecting line 60B, thereby achieving that different touch electrode blocks 501 in the same touch unit 50A are electrically connected to the same touch signal.

[0099] In some optional embodiments, please continue to refer to Figure 1-Figure 3 , Figure 8-Figure 13 In this embodiment, the touch electrode layer 50 further includes a plurality of floating touch units 50B;

[0100] Along the direction parallel to the plane where the substrate 10 is located, at least one floating touch unit 50B is included between two adjacent touch units 50A ( Figure 8 and Fig.10 In the example, a floating touch unit 50B is included between two adjacent touch units 50A for illustration); optionally, a single floating touch unit 50B includes at least one floating touch electrode block 50B1 or only includes one floating touch electrode block 50B1, which can make the distance between adjacent touch units 50A closer and meet the requirements of touch detection performance.

[0101] In this embodiment, the touch unit connection line 60A and the floating touch unit 50B are at least partially overlapped along the direction Z perpendicular to the plane where the substrate 10 is located. It should be noted that in order to clearly illustrate the overlapping structure of the touch unit connection line 60A and the floating touch unit 50B, Figure 8-Figure 11 The local area in the image is filled with transparency.

[0102] This embodiment explains that along the direction parallel to the plane where the substrate 10 is located, at least one floating touch unit 50B is included between two adjacent touch units 50A. The floating touch unit 50B can be understood as a touch unit that is not electrically connected to any touch signal, that is, the floating touch unit 50B does not receive any electrical signal. When the two adjacent touch units 50A are electrically connected through the touch unit connection line 60A along the direction parallel to the plane where the substrate 10 is located, for example, along the first direction X, the two adjacent receiving touch units 50A1 are electrically connected through the first connection line 60A1 included in the touch unit connection line 60A; along the second direction Y, the two adjacent transmitting touch units 50A2 are electrically connected through the second connection line 60A2 included in the touch unit connection line 60A, and along the direction Z perpendicular to the plane where the substrate 10 is located, the touch unit connection line 60A at least partially overlaps with the floating touch unit 50B. Since the floating touch unit 5 0B includes a floating touch electrode block 50B1 located in the touch electrode layer 50, and a touch unit connecting line 60A located in the drive array layer 20 below the binding electrode 30, that is, the touch unit connecting line 60A and the floating touch unit 50B are in different layers. The touch unit connecting line 60A and the floating touch unit 50B can be set to at least partially overlap in a direction Z perpendicular to the plane where the substrate 10 is located, that is, the touch unit connecting line 60A is directly routed under the floating touch unit 50B, which can avoid the winding of the touch unit connecting line 60A, which is beneficial to reducing the wiring difficulty of the signal line in the panel and improving the process efficiency.

[0103] In some optional embodiments, please refer to Fig.14 and Fig.15 , Fig.14 is another schematic diagram of a planar structure of a display panel provided by an embodiment of the present invention, Fig.15 yes Fig.14 Schematic diagram of the connection structure of the touch electrode layer and the touch electrode connection line in the middle part area. In this embodiment, the first connection line 60A1 includes a first sub-segment 60A11, a second sub-segment 60A12 and a third sub-segment 60A13. The second sub-segment 60A12 is in a different layer from the first sub-segment 60A11 and the third sub-segment 60A13. Along the direction Z perpendicular to the plane where the substrate 10 is located, the second sub-segment 60A12 at least partially overlaps with the floating touch unit 50B; or,

[0104] The second connecting line 60A2 includes a fourth sub-segment 60A21, a fifth sub-segment 60A22 and a sixth sub-segment 60A23. The fifth sub-segment 60A22 is in a different layer from the fourth sub-segment 60A21 and the sixth sub-segment 60A23. Along a direction Z perpendicular to the plane where the substrate 10 is located, the fifth sub-segment 60A22 at least partially overlaps with the floating touch unit 50B.

[0105] This embodiment explains that when at least one floating touch unit 50B is included between two adjacent touch units 50A in a direction parallel to the plane where the substrate 10 is located, any conductive film layer under the floating touch unit 50B can be used as an electrical connection structure between the two adjacent touch units 50A. Fig.14 and Fig.15As shown, along the first direction X, two adjacent receiving touch control units 50A1 are electrically connected through the first connecting line 60A1, and along the second direction Y, two adjacent transmitting touch control units 50A2 are electrically connected through the second connecting line 60A2. The first connecting line 60A1 includes a first sub-segment 60A11, a second sub-segment 60A12 and a third sub-segment 60A13. The second sub-segment 60A12 is in a different layer from the first sub-segment 60A11 and the third sub-segment 60A13. The second sub-segment 60A12 can be connected to a different film layer from the first sub-segment 60A11 and the third sub-segment 60A13 through a via hole. Along the direction Z perpendicular to the plane where the substrate 10 is located, the second sub-segment 60A12 at least partially overlaps with the floating touch control unit 50B, that is, the first connecting line 60A1 is located between the binding electrode 30 and the substrate 10. The first connecting line 60A1 can be set in a plurality of conductive film layers in the driving array layer 20. In order to realize the connection between two adjacent receiving touch control units in the first direction X, The electrical connection of the receiving touch control unit 50A1 can be electrically connected and led out from the receiving touch control unit 50A1 through the first sub-segment 60A11 of the first connecting line 60A1 located in the driving array layer 20, and then electrically connected to another conductive film layer in the driving array layer 20 through a via to form a second sub-segment 60A12, and then electrically connected from the second sub-segment 60A12 to the third sub-segment 60A13 located in the same layer as the first sub-segment 60A11, and then another receiving touch control unit 50A1 is electrically connected thereto, that is, the electrical connection structure of two adjacent receiving touch control units 50A1 in the first direction X includes a first connecting line 60A1 including at least three sections, which jumps through the first sub-segment 60A11 to the second sub-segment 60A12 in a different layer from the first sub-segment 60A11 below the floating touch control unit 50B, and then jumps back to the third sub-segment 60A13 in the same layer as the first sub-segment 60A11, thereby achieving the electrical connection effect of two adjacent receiving touch control units 50A1 in the first direction X. In this embodiment, by using any conductive film layer under the floating touch unit 50B as the electrical connection structure of two adjacent touch units 50A, it is possible to avoid the two adjacent receiving touch units 50A1 directly using the floating touch unit 50B made of transparent conductive material for electrical connection. Since the resistance of the metal conductive material is less than that of the transparent conductive material, using any conductive film layer under the floating touch unit 50B as the electrical connection structure of the two adjacent touch units 50A is beneficial to reducing the load of the first connection line 60A1 and improving the signal transmission performance. In the second direction Y, the two adjacent transmitting touch units 50A2 are still electrically connected through the second connection line 60A2 located in a conductive film layer in the drive array layer 20. The second connection line 60A2 and the first connection line 60A1 are in different layers, which can avoid the second connection line 60A2 and the first connection line 60A1 from interfering with each other, that is, avoiding the mutual interference between the touch driving signal and the driving sensing signal, which is beneficial to improving the touch performance.

[0106] Or similarly, Fig.16 and Fig.17As shown, Fig.16 is another schematic diagram of a planar structure of a display panel provided by an embodiment of the present invention, Fig.17 yes Fig.16Schematic diagram of the connection structure of the touch electrode layer and the touch electrode connection line in the middle part area, along the second direction Y, two adjacent transmitting touch units 50A2 are electrically connected through the second connection line 60A2, along the first direction X, two adjacent receiving touch units 50A1 are electrically connected through the first connection line 60A1, the second connection line 60A2 includes a fourth sub-segment 60A21, a fifth sub-segment 60A22 and a sixth sub-segment 60A23, the fifth sub-segment 60A22 is electrically connected to the fourth sub-segment 60A21, The sixth sub-segment 60A23 is on a different layer, and the fifth sub-segment 60A22 can be connected to a different film layer from the fourth sub-segment 60A21 and the sixth sub-segment 60A23 through a via hole. Along the direction Z perpendicular to the plane where the substrate 10 is located, the fifth sub-segment 60A22 at least partially overlaps with the floating touch unit 50B, that is, the second connecting line 60A2 located between the binding electrode 30 and the substrate 10. The second connecting line 60A2 can be set in multiple conductive film layers in the drive array layer 20. In order to achieve electrical connection between two adjacent transmitting touch units 50A2 in the second direction Y, the fourth sub-segment 60A21 of the second connecting line 60A2 located in the drive array layer 20 can be electrically connected and led out from the transmitting touch unit 50A2, and then electrically connected to another conductive film layer in the drive array layer 20 through a via hole to form the fifth sub-segment 60A22, and then the fifth sub-segment 60A22 is electrically connected to the sixth sub-segment 60A23 located in the same layer as the fourth sub-segment 60A21, and then the other transmitting touch unit is connected. 50A2 is electrically connected thereto, that is, the electrical connection structure of two adjacent transmitting touch control units 50A2 in the second direction Y includes a second connection line 60A2 including at least three sections, which jumps to a fifth sub-segment 60A22 under the floating touch control unit 50B and in a different layer from the fourth sub-segment 60A21, and then jumps back to a sixth sub-segment 60A23 in the same layer as the fourth sub-segment 60A21, thereby achieving an electrical connection effect of two adjacent transmitting touch control units 50A2 in the second direction Y. In this embodiment, by using any conductive film layer under the floating touch control unit 50B as the electrical connection structure of two adjacent touch control units 50A, it is possible to avoid directly using the floating touch control unit 50B made of transparent conductive material to electrically connect two adjacent transmitting touch control units 50A2. Since the resistance of the metal conductive material is less than that of the transparent conductive material, using any conductive film layer under the floating touch control unit 50B as the electrical connection structure of two adjacent touch control units 50A is beneficial to reducing the load of the second connection line 60A2 and improving the signal transmission performance. The two adjacent receiving touch units 50A1 in the first direction X are still electrically connected through the first connecting line 60A1 located in a conductive film layer in the driving array layer 20. The first connecting line 60A1 and the second connecting line 60A2 are in different layers, which can avoid mutual interference between the first connecting line 60A1 and the second connecting line 60A2, that is, avoid mutual interference between the touch driving signal and the driving sensing signal, which is beneficial to improving the touch performance.

[0108] The driving array layer 20 includes a thin film transistor 20T and a capacitor 20C. The active portion of the thin film transistor 20T is located in the semiconductor layer 201, the gate 20TG of the thin film transistor 20T is located in at least one of the second metal layer M1 and the first metal layer M0, and one plate 20C1 of the capacitor 20C is located in the third metal layer Mc.

[0109] Optionally, the driving array layer 20 further includes a fourth metal layer M2 and a fifth metal layer M3;

[0110] Along a direction Z perpendicular to the plane where the substrate 10 is located, the fourth metal layer M2 is located on a side of the third metal layer Mc away from the substrate, and the fifth metal layer M3 is located between the fourth metal layer M2 and the binding electrode 30;

[0111] The display panel 000 includes a plurality of first power signal lines PVDD and a plurality of data lines DATA;

[0112] The data line DATA and a portion of the first power signal line PVDD are located in the fourth metal layer M2 , and at least a portion of the first power signal line PVDD is located in the fifth metal layer M3 (not shown in the figure).

[0113] This embodiment explains the film structure of the display panel 000, specifically, the conductive film structure of the drive array layer 20 can be in the direction away from the substrate 10, and the drive array layer 20 includes at least a first metal layer M0, a semiconductor layer 201, a second metal layer M1, a third metal layer Mc, a fourth metal layer M2 and a fifth metal layer M3 in sequence, wherein the semiconductor layer 202 is located between the first metal layer M0 and the second metal layer M1. The conductive film layer of the drive array layer 20 is generally used to make thin film transistors 20T, capacitors 20C and various types of drive signal wiring, etc. The drive signal wiring can be a scan line, a data line, a power line, a reset line, etc. This embodiment does not give examples one by one, and can be understood by referring to the film structure of the display panel in the relevant technology. The drive array layer 20 of this embodiment may include a thin film transistor 20T, a capacitor 20C, a plurality of first power signal lines PVDD and a plurality of data lines DATA. The first power signal line PVDD is used to provide a first power signal for the pixel circuit in the display panel 000, and the data line DATA is used to provide a data voltage signal for the pixel circuit in the display panel 000. The active portion of the thin film transistor 20T of the present embodiment is located in the semiconductor layer 201, and the gate 20TG of the thin film transistor 20T is located in at least one of the second metal layer M1 and the first metal layer M0. For example, the gate of the thin film transistor 20T can be located in the second metal layer M1, in which case the thin film transistor 20T is a top-gate transistor. The gate of the thin film transistor 20T can also be located in the first metal layer M0, in which case the thin film transistor 20T is a bottom-gate transistor. The thin film transistor 20T can also be a dual-gate transistor, in which the top gate and the bottom gate are located in the second metal layer M1 and the first metal layer M0, respectively. The present embodiment does not limit the type of the thin film transistor 20T, and it is only required that the driving array layer 20 of the display panel 000 includes the above-mentioned metal conductive layer, so as to meet the needs of manufacturing different types of thin film transistors 20T. The first metal layer M0 of this embodiment is located on the side of the semiconductor layer 201 facing the substrate 10. The first metal layer M0 can also be used as a light shielding layer to shield the active part of the thin film transistor 20T of the semiconductor layer 201. The specific setting structure of the first metal layer M0 is not limited in this embodiment. When it is implemented, it can be designed according to actual needs. One plate 20C1 of the capacitor 20C in the pixel circuit of the display panel 000 is located in the third metal layer Mc, and the other plate 20C1 of the capacitor 20C can be located in the fourth metal layer M2, or in the fifth metal layer M3, or in the second metal layer M1. This embodiment does not limit this. The fourth metal layer M2 can be used to make the data line DATA and part of the first power signal line PVDD. The fourth metal layer M2 can also be used to make the source and drain of the thin film transistor 20T. The fourth metal layer M2 is close to the semiconductor layer 201, so the data line DATA and part of the first power signal line PVDD are set in the fourth metal layer M2, which can be easily electrically connected to the active part of the thin film transistor 20T of the semiconductor layer 201.The fifth metal layer M3 is located between the fourth metal layer M2 and the binding electrode 30, that is, the fifth metal layer M3 is located on the side of the fourth metal layer M2 away from the substrate 10, and at least part of the first power signal line PVDD is located in the fifth metal layer M3. The first power signal line PVDD located in the fourth metal layer M2 and the first power signal line PVDD located in the fifth metal layer M3 can be connected in parallel, which is beneficial to reducing the impedance of the first power signal line PVDD and improving the signal transmission performance.

[0114] It is understandable that this embodiment is only an example to illustrate the film layer and setting structure of the driving array layer 20 in the display panel 000. In specific implementation, the film layer structure of the driving array layer 20 includes but is not limited to this and can be set according to actual needs. This embodiment will not be described in detail here.

[0115] In this embodiment, the touch unit connection line 60A includes a first connection line 60A1 and a second connection line 60A2. Along the first direction X, two adjacent receiving touch units 50A1 are electrically connected through the first connection line 60A1 (eg, Fig.19 Along the second direction Y, two adjacent emitting touch control units 50A2 are electrically connected via a second connecting line 60A2 (it can be understood that due to the limited space of the cross-sectional view, in order to clearly illustrate the structure of the thin film transistor, Fig.18 The first connection line 60A1 and the second connection line 60A2 are arranged in different layers, and the first connection line 60A1 and the second connection line 60A2 are arranged in a certain conductive film layer of the drive array layer 20, so that the touch unit connection line 60A is located on the side of the binding electrode 30 facing the substrate 10. The first connection line 60A1 and the second connection line 60A2 are arranged in different layers, so that the first connection line 60A1 electrically connecting two adjacent receiving touch units 50A1 and the second connection line 60A2 electrically connecting two adjacent transmitting touch units 50A2 can cross and be insulated, so as to avoid mutual interference between the touch driving signal and the touch sensing signal, which is conducive to ensuring the touch detection performance.

[0116] Optionally, the present embodiment does not limit the film layers for setting the first connection line 60A1 and the second connection line 60A2. The first connection line 60A1 can be set on the first metal layer M0, and the second connection line 60A2 can be set on the second metal layer M1 or the third metal layer Mc (such as Fig.18 The first connection line 60A1 may be disposed in the second metal layer M1 or the third metal layer Mc, and the second connection line 60A2 may be disposed in the first metal layer M0, and it is only necessary that the first connection line 60A1 and the second connection line 60A2 are in different layers.

[0117] In this embodiment, the film layer where the first connection line 60A1 and the second connection line 60A2 are set is located as far as possible in the first metal layer M0, the second metal layer M1 or the third metal layer Mc, and is avoided as far as possible in the fourth metal layer M2 and the fifth metal layer M3, so that the fourth metal layer M2 and the fifth metal layer M3 have enough space to lay out the first power signal line PVDD and the data line DATA, so that the space of the fourth metal layer M2 and the fifth metal layer M3 can be fully utilized, and the routing area of ​​the first power signal line PVDD can be set as large as possible, which is beneficial to reducing the IR-drop of the first power signal line PVDD and improving the signal transmission effect. In addition, at least one of the first connection line 60A1 and the second connection line 60A2 is located in the first metal layer M0, and the first metal layer M0 has more space than other metal layers, so the IR-drop on the first power signal line PVDD can be reduced by reasonably utilizing the space of the panel film layer, thereby ensuring the display quality.

[0118] In some optional embodiments, such as Figure 1 , Figure 8 , Fig.10 , Fig.18 The display panel 000 in this embodiment includes a plurality of pixel units 00, and the pixel unit 00 includes at least three light-emitting devices 40 of different colors (illustrated by different filling patterns in the figure);

[0119] Along the second direction Y, at least one pixel unit 00 is included between two adjacent touch electrode blocks 501. Optionally, the display panel 000 of this embodiment may be a transparent display panel, the display panel 000 includes a light-transmitting area TA and a light-emitting area FA, the light-emitting device 40 is located in the light-emitting area FA, and the touch electrode block 501 in the touch unit 50A is located in the light-transmitting area TA.

[0120] This embodiment explains that the display panel 000 can be a transparent display panel. Since the touch unit 50A of the touch electrode layer 50 is generally made of transparent conductive material, the light transmittance is high, and the area where the touch unit 50A is located can be understood as the light-transmitting area TA. The area where the light-emitting device 40 is located can be understood as the light-emitting area FA. In this embodiment, the film layer for making the first connecting line 60A1 and the second connecting line 60A2 is located as much as possible in the first metal layer M0, the second metal layer M1 or the third metal layer Mc, and is avoided as much as possible in the fourth metal layer M2 and the fifth metal layer M3, so that the fourth metal layer M2 and the fifth metal layer M3 can have enough space to lay out the first power signal line PVDD and the data line DATA, so that the space of the fourth metal layer M2 and the fifth metal layer M3 can be fully utilized, and the routing area of ​​the first power signal line PVDD can be set as large as possible, which is conducive to reducing the IR-drop of the first power signal line PVDD and improving the signal transmission effect. In addition, the first connecting line 60A1 and the second connecting line 60A2 do not occupy the fourth metal layer M2 and the fifth metal layer M3, so that the setting area of ​​the opaque structure of the fourth metal layer M2 and the fifth metal layer M3 (such as the data line and the first power signal line can be located in the light-emitting area FA as much as possible) can be minimized, ensuring that the opaque structure of the fourth metal layer M2 and the fifth metal layer M3 does not occupy the light-transmitting area TA, which can effectively improve the transmittance of the display panel 000 and ensure a transparent display effect.

The second metal layer M1 forms a second sub-segment 60A12. At this time, the second connecting line 60A2 can be located in the third metal layer Mc. After the second sub-segment 60A12 is electrically connected to the third sub-segment 60A13 located in the same layer as the first sub-segment 60A11 (the third sub-segment 60A13 is also located in the first metal layer M0), another receiving touch unit 50A1 is electrically connected to it. That is, the electrical connection structure of two adjacent receiving touch units 50A1 in the first direction X includes a first connecting line 60A1 that includes at least three sections. The first connecting line 60A1 is jumped through the first sub-segment 60A11 to the second sub-segment 60A12 in a different layer from the first sub-segment 60A11 below the floating touch unit 50B, and then jumped back to the third sub-segment 60A13 in the same layer as the first sub-segment 60A11, so as to achieve the electrical connection effect of two adjacent receiving touch units 50A1 in the first direction X.

Along the second direction Y, the two adjacent transmitting touch control units 50A2 are electrically connected through the second connecting line 60A2. Along the first direction X, the two adjacent receiving touch control units 50A1 are electrically connected through the first connecting line 60A1, that is, the second connecting line 60A2 located between the binding electrode 30 and the substrate 10. The second connecting line 60A2 can be set in multiple conductive film layers in the driving array layer 20. In order to realize the electrical connection of two adjacent transmitting touch control units 50A2 in the second direction Y, the fourth sub-segment 60A21 of the second connecting line 60A2 located in the driving array layer 20 can be electrically connected from the transmitting touch control unit 50A2. The fourth sub-segment 60A21 of the second connecting line 60A2 is located in the first metal layer M0, and then electrically connected to the driving array through a via. The second metal layer M1 in layer 20 forms a fifth sub-segment 60A22. At this time, the first connecting line 60A1 can be located in the third metal layer Mc. After being electrically connected from the fifth sub-segment 60A22 to the sixth sub-segment 60A23 located on the same layer as the fourth sub-segment 60A21 (the sixth sub-segment 60A23 is also located in the first metal layer M0), another transmitting touch unit 50A2 is electrically connected to it, that is, the electrical connection structure of two adjacent transmitting touch units 50A2 in the second direction Y includes a second connecting line 60A2 that includes at least three sections, which jumps through the fourth sub-segment 60A21 to the fifth sub-segment 60A22 on a different layer from the fourth sub-segment 60A21 below the floating touch unit 50B, and then jumps back to the sixth sub-segment 60A23 on the same layer as the fourth sub-segment 60A21, thereby achieving the electrical connection effect of two adjacent transmitting touch units 50A2 in the second direction Y.

[0130] Optionally, the first sub-line 60B1 and the second sub-line 60B2 are located in the same layer; and / or the third sub-line 60B3 and the fourth sub-line 60B4 are located in the same layer; that is, the film layer where the first sub-line 60B1 and the second sub-line 60B2 are located is different from the film layer where the third sub-line 60B3 and the fourth sub-line 60B4 are located.

[0131] Optionally, the first sub-line 60B1 is located in the first metal layer M0, and the third sub-line 60B3 is located in one of the second metal layer M1 and the third metal layer Mc.

The touch electrode block connection line 60B includes a first sub-line 60B1, a second sub-line 60B2, a third sub-line 60B3 and a fourth sub-line 60B4; the first touch electrode block 5011, the second touch electrode block 5012, the third touch electrode block 5013, the fourth touch electrode block 5014 and the fifth touch electrode block 5015 are electrically connected through the touch electrode block connection line 60B.

The first binding pad PIN1 can be located in an area for subsequent binding of a driver chip. Through the binding of the driver chip, the touch sensing signal is received to the first binding pad PIN1 through the receiving signal line RX, and the output of the touch detection signal is realized through the subsequent bound driver chip. When performing touch detection, the touch drive signal provided by the driver chip is output to the transmission signal line TX through the second binding pad PIN2, and transmitted to each transmitting unit column 50A2L, and the touch drive signal is input to the multiple transmitting touch units 50A2 of the transmitting unit column 50A2L through the second connection line 60A2, and the touch sensing signals of the multiple receiving touch units 50A1 in the receiving unit row 50A1H are received and detected through the first connection line 60A1, and the touch sensing signals are received to the first binding pad PIN1 through the receiving signal line RX, and the output of the touch detection signal is realized through the subsequent bound driver chip. When the touch subject touches the display panel 000, the sensing signal on the receiving touch unit 50A1 at the touch position changes, and the touch position can be determined according to the touch sensing signal received and detected by the first connection line 60A1 and transmitted to the receiving signal line RX of the current row, so as to achieve the touch detection effect.

[0140] Optionally, the receiving signal line RX and the transmitting signal line TX in this embodiment can be made of a conductive film layer in the driving array layer 20, and the film layer where the receiving signal line RX is located and the film layer where the transmitting signal line TX is located can be in the same layer, and it is only necessary to avoid cross-circuiting between the receiving signal line RX and the transmitting signal line TX.

[0141] Optionally, the receiving signal line RX and the transmitting signal line TX in this embodiment can be made of at least two different conductive film layers in the driving array layer 20, and the receiving signal line RX and the transmitting signal line TX can be arranged in different layers, such as Fig.18 As shown, the receiving signal line RX can be made of the first metal layer M0, and the transmitting signal line TX can be made of the second metal layer M1 or the third metal layer Mc, or the receiving signal line RX can be made of the second metal layer M1 or the third metal layer Mc, and the transmitting signal line TX can be made of the first metal layer M0. The setting film layer of the receiving signal line RX and the transmitting signal line TX can be avoided from the setting film layer of the first power signal line PVDD, which is beneficial to leave sufficient setting space for the first power signal line PVDD to ensure its signal transmission performance.

[0142] Optional, please refer to Figure 8 , Fig. 9 , Fig.25 , Fig.25 is another schematic diagram of a planar structure of a display panel provided by an embodiment of the present invention. In this embodiment, at least part of the receiving signal lines RX are located in the display area AA. That is, the receiving signal lines RX can be drawn from the first connecting line 60A1 between two adjacent receiving touch units 50A1 in the receiving unit row 50A1H, and then routed from the display area AA to be electrically connected to the first binding pad PIN1 in the non-display area NA (e.g., Fig.25 or at least part of the transmitting signal line TX is located in the display area AA, that is, the transmitting signal line TX can be led out from the second connecting line 60A2 between two adjacent transmitting touch control units 50A2 in the transmitting unit column 50A2L, and then routed from the display area AA, and electrically connected to the second binding pad PIN2 of the non-display area NA (not shown in the figure); or at least part of the receiving signal line RX is located in the display area AA, and at least part of the transmitting signal line TX is located in the display area AA, that is, at least part of the receiving signal line RX and the transmitting signal line TX are routed from the display area AA, and then electrically connected to the non-display area N On the binding pad of A, since the setting film layer of the receiving signal line RX and the transmitting signal line TX avoids the setting film layer of the first power signal line PVDD, and the setting film layer of the receiving signal line RX and the transmitting signal line TX is set as much as possible on the first metal layer M0, the second metal layer M1 or the third metal layer Mc with abundant space, at least part of the segments or part of the receiving signal line RX and the transmitting signal line TX are routed from the display area AA, which can avoid short circuit with the data line and the first power signal line PVDD, and can also effectively reduce the space of the frame non-display area NA, which is conducive to realizing the narrow frame design of the display panel 000.

[0143] Alternatively, in some other optional embodiments, the receiving signal line RX is located in the non-display area NA, and the transmitting signal line TX is located in the non-display area NA. Since the film layers of the receiving signal line RX and the transmitting signal line TX are set as much as possible in the first metal layer M0, the second metal layer M1 or the third metal layer Mc with sufficient space, even if the first power signal line PVDD is wound in the non-display area NA, it is wound in the fourth metal layer M2 and the fifth metal layer M5 of the non-display area NA. Therefore, the receiving signal line RX and the transmitting signal line TX are set in the non-display area NA, and can overlap with the winding of the first power signal line PVDD in the non-display area NA but in different layers, so they will not interfere with each other, and the narrow frame effect of the display panel 000 can also be achieved.

[0144] In some alternative embodiments, please refer to Fig.26 , Fig.26 001 and 002 are schematic diagrams of another planar structure of a display panel provided in an embodiment of the present invention (it can be understood that in order to clearly illustrate the gate driving circuit 001 and the pixel circuit 002 of this embodiment, Fig.26 Transparency is filled in. Fig.26 Only a part of the electrical connection structure between the gate driving circuit 001 and the pixel circuit 002 and the light-emitting device is schematically shown.

Since the touch electrode block 501 of the touch electrode layer 50 is located above the binding electrode 30, even if the orthographic projection of at least part of the touch electrode block 501 on the plane where the substrate 10 is located overlaps with the gate driving circuit 001, it will not affect the transmission effect of the electrical signal between the gate driving circuit 001 and the light-emitting device 40 bound to the binding electrode 30, and can effectively take into account both the display quality and the touch performance.

[0149] When the display panel 000 is a frameless display panel, the gate drive circuit 001 can also be arranged in the display area AA. When the gate drive circuit 001 is located in the display area AA, the orthographic projection of at least part of the touch electrode block 501 on the plane where the substrate 10 is located overlaps with the gate drive circuit 001, thereby making full use of the spatial layout of the panel film layer, and the touch electrode block 501 of the touch electrode layer 50 is located above the binding electrode 30, even if the orthographic projection of at least part of the touch electrode block 501 on the plane where the substrate 10 is located overlaps with the gate drive circuit 001, it will not affect the transmission effect of the electrical signal between the gate drive circuit 001 and the light-emitting device 40 bound to the binding electrode 30, and can effectively take into account both the display quality and the touch performance.

[0150] The pixel circuit 002 in this embodiment can be arranged in the display area AA, and the orthographic projection of at least part of the touch electrode block 501 on the plane where the substrate 10 is located overlaps with the pixel circuit 002, so that the spatial layout of the panel film layer can be fully utilized, and the touch electrode block 501 of the touch electrode layer 50 is located above the binding electrode 30. Even if the orthographic projection of at least part of the touch electrode block 501 on the plane where the substrate 10 is located overlaps with the pixel circuit 002, it will not affect the transmission effect of the electrical signal between the pixel circuit 002 and the light-emitting device 40 bound to the binding electrode 30, and can effectively take into account both the display quality and the touch performance.
