Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display panel and display device. Background Technology

[0002] With the development of display technology, more and more fully flexible display products are gradually coming into people's view. Compared with rigid screens and flat screens, fully flexible displays have some drawbacks while achieving full flexibility and ultra-thinness. For example, in an ultra-thin form, electrostatic effects may damage the internal structural circuits and light-emitting materials, ultimately directly affecting the lifespan of the fully flexible display. Summary of the Invention

[0003] Therefore, it is necessary to provide a display panel and display device that can reduce the impact of electrostatic effects on the lifespan of the display screen.

[0004] According to one aspect of this application, a display panel is provided, comprising:

[0005] Display substrate;

[0006] A cover plate is disposed on one side of the display substrate; and

[0007] The discharge structure is located between the display substrate and the cover plate;

[0008] The discharge structure includes at least one transmission section, which has a discharge tip and a connection end at both ends. The discharge tip is located on the side of the cover plate close to the display substrate. The transmission section receives external voltage through the discharge tip and discharges it to the outside of the display panel through the connection end.

[0009] When the aforementioned display panel is subjected to external high voltage or electrostatic discharge, a discharge effect can be generated at the discharge tip of the transmission section. The high voltage or electrostatic discharge is then rapidly absorbed and conducted to the connection end through the transmission section, and then discharged to the outside through the connection end. This ultimately reduces damage to the array substrate and device layer of the display substrate, thereby improving the service life of the display panel.

[0010] In one embodiment, the discharge tips of the plurality of transmission units are spaced apart, the plurality of transmission units are arranged in a row along a first direction, and the plurality of transmission units are arranged in a column along a second direction;

[0011] The first direction intersects with the second direction. Discharge effects can be generated through multiple discharge tips, expanding the range of external voltages the discharge structure can receive, and voltage can be quickly discharged through multiple connection terminals. Furthermore, this allows the transmission sections to be arranged in a regular pattern, resulting in a more uniform display.

[0012] In one embodiment, the transmission unit includes multiple sub-transmission units, which are arranged radially from the cover plate toward the display substrate. Because the multiple sub-transmission units are arranged radially, concentrated voltage can be quickly dispersed, thereby allowing the voltage to be quickly absorbed and conducted to the connection terminal, and then discharged to the outside.

[0013] In one embodiment, the transmission section is tapered. This not only ensures the pressure relief effect but also provides some support for the cover plate and maintains its shape even when the display panel is bent.

[0014] In one embodiment, the transmission section includes at least three sub-transmission sections. This arrangement provides robust support and high transmittance.

[0015] In one embodiment, each sub-transmission unit has a sub-discharge tip and a sub-connection end at both ends. The sub-discharge tips of multiple sub-transmission units are connected at the discharge tips, and the sub-connection ends of multiple sub-transmission units are separated from each other at the connection ends. This simplifies the structure of the sub-transmission units of the transmission unit.

[0016] In one embodiment, the display panel further includes a reinforcing portion that fills the space between two adjacent transmission portions and between each of the sub-transmission portions of each transmission portion. This allows the transmission portions to maintain their shape.

[0017] In one embodiment, the display substrate includes a display area and a non-display area disposed at least partially surrounding the display area;

[0018] The discharge structure also includes a pressure relief section located in the non-display area. The pressure relief section is connected to the connection terminals of each transmission section, and the connection terminals discharge the external voltage to the outside through the pressure relief section. This allows the external voltage to be quickly transmitted to the non-display area, thereby avoiding damage to the array substrate and device layers in the display area caused by the voltage remaining in the display area.

[0019] In one embodiment, the discharge structure further includes a pressure relief conduction section, and the connection terminals of each transmission section are connected to the pressure relief conduction section, which in turn is connected to the pressure relief section. The external voltage can be rapidly conducted to the pressure relief section through the pressure relief conduction section.

[0020] In one embodiment, the connection terminals of every two adjacent transmission sections are directly connected, and the pressure relief conduction section connects the connection terminals of every two adjacent transmission sections that are connected to each other. This allows the external voltage transmitted from each transmission section to the connection terminal to be transmitted to the outside at the fastest possible speed.

[0021] In one embodiment, the pressure relief transmission section includes multiple parallel and spaced sub-pressure relief transmission sections. At least one transmission section is provided between each pair of adjacent sub-pressure relief transmission sections. Each sub-pressure relief transmission section can connect to at least one connection end of each pair of adjacent transmission sections, and both ends of each sub-pressure relief transmission section are connected to the pressure relief section. This arrangement of the pressure relief transmission sections in a certain regularity avoids a complex configuration.

[0022] In one embodiment, the display panel further includes a touch layer disposed between the display substrate and the cover plate, and a discharge structure disposed between the touch layer and the cover plate. This avoids damage to the touch layer caused by high voltage or static voltage.

[0023] In one embodiment, the touch layer includes a plurality of touch electrodes, with a first gap between adjacent touch electrodes, and the orthographic projection of the connection end of any transmission part falls within the first gap. This avoids the connection end and pressure relief conduction part from being superimposed directly above the touch electrodes, which could cause display differences and thus affect the display of the display panel.

[0024] In another aspect of this application, a display device is also provided, including the display panel described above.

[0025] When the display panel is subjected to external high voltage or electrostatic shock, the above-mentioned display device can generate a discharge effect through the discharge tip of the transmission section, and quickly absorb and conduct the high voltage or electrostatic voltage to the connection end through the transmission section, and then discharge it to the outside through the connection end, thereby reducing damage to the array substrate and device layer of the display substrate and improving the service life of the display panel.

[0038] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0039] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0040] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms such as "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0041] As mentioned in the background section, fully flexible display products are ultra-thin. To achieve this ultra-thin characteristic, compared to rigid screens and flat screens, fully flexible displays are equipped with thinner touch layers, cover plates, and TFT driving layers. Under this structure, if the display is subjected to external stimuli or static voltage, it will be at greater risk of damage, and the display life of OLED devices will also be affected.

[0042] Therefore, it is necessary to provide a display panel and display device that can reduce the impact of electrostatic effects on the lifespan of the display screen.

[0043] like Figure 1 and Figure 2 As shown, the display panel 100 of this application includes a display substrate 10, a cover plate 20, and a discharge structure 30.

[0044] The display substrate 10 includes a display area AA and a non-display area NAA that at least partially surrounds the display area. In embodiments of this application, the non-display area NAA is disposed around the display area AA. Specifically, the display area AA is rectangular, and the non-display area NAA is configured to surround the rectangular display area AA.

[0045] The display substrate 10 includes a substrate, an array substrate, and a device layer disposed on the substrate. Specifically, the substrate is a flexible substrate, and the device layer is located in the display area AA to realize the display of the image. The device layer includes a cathode, an electron injection layer, an electron transport layer, a light-emitting layer, a hole transport layer, a hole injection layer, and an anode. Electrons from the cathode and holes from the anode are injected into the electron injection layer and the hole injection layer, respectively, under the driving action of an electric field, and then migrate to the light-emitting layer via the electron transport layer and the hole transport layer. Electrons and holes combine in the light-emitting layer to generate excitons, and the excitons emit light by migration and radiation attenuation. The array substrate includes multiple arrays of thin-film transistors that drive the device layer. The thin-film transistors generate driving signals according to the signals output by the driving chip, such as driving signals generated according to the signals on the scan signal line and the data signal line, to drive the device layer to emit light.

[0046] A cover plate 20 is disposed on one side of the display substrate 10. Specifically, it can be a flexible cover plate. The cover plate 20 can be bent integrally with the display substrate 10 to protect the display substrate 10 and reduce the impact of external impacts on the display substrate 10. It also provides a certain surface hardness to the display substrate 10 to facilitate subsequent terminal assembly. Specifically, the cover plate 20 can also be a bendable ultra-thin glass (UTG), which is not limited here.

[0047] like Figure 3 As shown, the discharge structure 30 of this application is located between the display substrate 10 and the cover plate 20. The discharge structure 30 includes at least one transmission section 31. The two ends of the transmission section 31 have discharge tips 311 and connection ends 312. The discharge tips 311 are located on the side of the cover plate 20 near the display substrate 10. The transmission section 31 receives external voltage through the discharge tips 311 and discharges it to the outside of the display panel 100 through the connection ends 312. Specifically, the transmission section 31 is located within the display area AA, so that it can receive external voltage within the display area AA.

[0048] It should be noted that the external voltage referred to in this application includes electrostatic voltage or high voltage inside the display terminal. Electrostatic voltage refers to the electrostatic voltage generated when a human body or an object other than the display panel 100 comes into contact with the display panel 100. High voltage inside the display terminal refers to the internal voltage generated when the electronic components inside it are working.

[0049] In the embodiments of this application, the discharge tip 311 contacts the cover plate 20 to receive external static electricity from the cover plate 20. Specifically, the discharge tip 311 can directly contact the cover plate 20 or indirectly contact it through the layer structure, which is not limited here.

[0050] In addition, in the embodiments of this application, in order to avoid the influence of external static electricity received by the discharge tip 311 on the connection end 312, the discharge tip 311 is set closer to the cover plate 20 than the connection end 312.

[0051] Thus, when the display panel 100 is subjected to external high voltage or electrostatic shock, a discharge effect can be generated at the discharge tip 311 of the transmission section 31, and the high voltage or electrostatic voltage can be quickly absorbed and conducted to the connection end 312 through the transmission section 31, and then discharged to the outside through the connection end 312, thereby reducing damage to the array substrate and device layer of the display substrate 10 and improving the service life of the display panel 100.

[0052] like Figure 4 As shown, in some embodiments, the number of transmission sections 31 includes multiple sections, and the discharge tips 311 of the multiple transmission sections 31 are arranged at intervals. Specifically, in order to make the positional relationship between the transmission sections 31 more compact, the connection ends 312 of each pair of adjacent transmission sections 31 are directly connected. Therefore, by providing multiple transmission sections 31, a discharge effect can be generated through multiple discharge tips 311, which can expand the range of external voltage received by the discharge structure 30, and the voltage can be quickly discharged through multiple connection ends 312.

[0053] In some embodiments, all transmission units 31 can be arranged in an array. For example, multiple transmission units 31 can be arranged in a row along a first direction, and multiple transmission units 31 can be arranged in a column along a second direction, wherein the first direction and the second direction intersect. This allows the transmission units 31 to be arranged in a regular pattern, resulting in a more uniform display. In other embodiments, they can also be arranged unevenly. For example, for certain areas where voltage discharge needs to be accelerated, a larger number of transmission units 31 can be provided per unit area, while for certain areas that may not be subject to external high voltage or electrostatic discharge, a smaller number of transmission units 31 can be provided per unit area, or even no transmission units 31 can be provided.

[0054] Please refer to it again. Figure 3In some embodiments, the transmission unit 31 includes a plurality of sub-transmission units 313, which are arranged radially from the cover plate 20 toward the display substrate 10. After the discharge tip 311 of the transmission unit 31 receives an external voltage, the concentrated voltage can be quickly dispersed due to the radial arrangement of the plurality of sub-transmission units 313, thereby allowing the voltage to be quickly absorbed and conducted to the connection terminal 312, and then discharged to the outside.

[0055] Furthermore, each sub-transmission section 313 has a sub-discharge tip and a sub-connection end at both ends. The sub-discharge tips of multiple sub-transmission sections 313 are connected together, and the sub-connection ends of multiple sub-transmission sections 313 are separated from each other. In this way, the structure of the sub-transmission sections 313 of the transmission section 31 can be simplified. In other embodiments, the sub-discharge tips of multiple sub-transmission sections 313 can converge to form a discharge tip 311. Of course, the discharge tip 311 can also be an independent structure connected to the sub-discharge tips.

[0056] In some embodiments, the transmission section 31 is conical. That is, multiple sub-transmission sections 313 are arranged in a conical shape, and each sub-transmission section 313 forms the edge of the conical transmission section 31. Setting the transmission section 31 in a conical shape allows the transmission section 31 to have a stable structure, thereby making the discharge structure 30 have a stable structure. On the one hand, it can not only ensure the pressure relief effect, but also support the cover plate 20 to a certain extent. In addition, it can maintain its shape when the display panel 100 is bent.

[0057] In specific embodiments of this application, each transmission unit 31 includes at least three sub-transmission units 313, which provides robust support and high transmittance. In a preferred embodiment, each transmission unit 31 includes four sub-transmission units 313. In other embodiments, each transmission unit 31 may also include three or five sub-transmission units 313, and this is not limited thereto.

[0058] Please refer to it again. Figure 2 In some embodiments, to maintain the shape of the transmission section 31, the display panel 100 further includes a reinforcing section 40, which fills the space between two adjacent transmission sections 31 and each sub-transmission section 313 of each transmission section 31. Specifically, the reinforcing section 40 may be formed by curing a free-flowing adhesive. Specifically, the material of the reinforcing section 40 is an optical resin.

[0059] In the embodiments of this application, the transmission unit 31 may be made of nanomaterials. Specifically, when the transmission unit 31 is located in the display area AA, it may be made of nanomaterials with good light transmittance, such as gold, silver, copper, cobalt, platinum, etc. These materials not only have good light transmittance, but also good electrical conductivity.

[0060] In some embodiments, the discharge structure 30 further includes a pressure relief section 32 disposed in the non-display area NAA. The pressure relief section 32 is connected to the connection terminal 312 of each transmission section 31, and the connection terminal 312 discharges the external voltage to the outside through the pressure relief section 32. By providing the pressure relief section 32 in the non-display area NAA, the external voltage can be quickly transmitted to the non-display area NAA, thereby avoiding damage to the array substrate and device layer in the display area AA caused by the voltage remaining there. Specifically, the pressure relief section 32 can be made of a metallic material.

[0061] Please refer to it again. Figure 4 Furthermore, the non-display area NAA is arranged to surround the display area AA, and the pressure relief section 32 is arranged to surround the display area AA. In this way, the connection terminal 312 can conduct voltage to the pressure relief section 32 in a circumferential manner, thereby improving the pressure relief speed.

[0062] In a specific embodiment of this application, the discharge structure 30 further includes a pressure relief conduction section, the connection end 312 of each transmission section 31 is connected to the pressure relief conduction section, and the pressure relief conduction section is connected to the pressure relief section 32. Thus, the external voltage can be quickly conducted to the pressure relief section 32 through the pressure relief conduction section.

[0063] More specifically, when there are multiple transmission units 31, and the connection terminals 312 of two adjacent transmission units 31 are directly connected, the pressure relief transmission unit can connect the connection terminals 312 of each two adjacent transmission units 31. In this way, the external voltage transmitted from each transmission unit 31 to the connection terminal 312 can be transmitted to the outside at the fastest speed.

[0064] In a preferred embodiment, the pressure relief transmission section connects two adjacent sub-connection ends 312 of the transmission section 31, and connects the sub-connection ends 312 of each adjacent two transmission sections 31 that are connected to each other.

[0065] In a preferred embodiment, the pressure relief conduction section includes multiple parallel and spaced-apart sub-pressure relief conduction sections. At least one transmission section 31 is provided between every two connected sub-pressure relief conduction sections. Each sub-pressure relief conduction section can connect to at least one connection end of at least two adjacent transmission sections 31, and both ends of each sub-pressure relief conduction section are connected to the pressure relief section. This arrangement of the pressure relief conduction sections in a certain regularity avoids complex configurations. Specifically, in the embodiments of this application, the sub-pressure relief conduction sections are conductive wires. To more clearly illustrate the location of the sub-pressure relief conduction sections, the appendix of this application... Figure 4 The pressure relief transmission section is schematically represented by lines connecting aa, bb, and cc.

[0066] To facilitate the connection between the pressure relief conduction section and the pressure relief section 32 in the non-display area NAA, the discharge structure 30 also includes a connecting wire. One end of the connecting wire is connected to the pressure relief section 32, and the other end is connected to the pressure relief conduction section. Specifically, the connecting wire includes a plurality of sub-connecting wires 33. One end of each sub-connecting wire is connected to the pressure relief section 32, and the other end is connected to one end of the sub-pressure relief conduction section.

[0067] In the embodiments of this application, the non-display area (NAA) includes a bonding area, and the pressure relief part 32 can be connected to a terminal in the bonding area. The terminal can be connected to the housing of the display device or other non-display devices or non-driving lines to relieve pressure.

[0068] Please refer to it again. Figure 2 In some embodiments, the display panel 100 further includes a touch layer 50 disposed between the display substrate 10 and the cover plate 20, and a discharge structure 30 disposed between the touch layer 50 and the cover plate 20. This avoids damage to the touch layer 50 from high voltage or static voltage.

[0069] Specifically, the connection end 312 of the transmission unit 31 is in contact with the touch layer 50. Specifically, the connection end 312 can be in direct contact with the touch layer 50 or indirect contact through the layer structure, which is not limited here.

[0070] More specifically, the touch layer 50 includes multiple touch electrodes, and the connection terminal 312 is disposed on a different layer from the touch electrodes. Specifically, when the connection terminal 312 of each transmission section 31 is connected to the pressure relief conduction section, the pressure relief conduction section is disposed on a different layer from the touch electrodes. In some embodiments, the connection terminal 312 and the pressure relief conduction section are located above the touch electrodes.

[0071] In other embodiments, the connection end 312 and the pressure relief and conduction part can also be disposed on the same layer as the touch layer 50.

[0072] It should be noted that the connection end 312 and the pressure relief conductive part are insulated from the touch electrode.

[0073] In some embodiments, a first gap exists between two adjacent touch electrodes, and the orthographic projection of the connection end 312 of any transmission section 31 onto the touch layer 50 falls within the first gap. Furthermore, the orthographic projection of the pressure relief transmission section onto the touch layer 50 also falls within the first gap. This avoids the connection end 312 and the pressure relief transmission section from overlapping directly above the touch electrodes, thus preventing display differences and ensuring the display panel 100 is not affected.

[0074] It should be noted that the portion of each transmission section 31, excluding the connection end 312, is projected onto the corresponding touch electrode in the touch layer 50. In a preferred embodiment, the arrangement of each transmission section 31 of the discharge structure 30 can correspond to the arrangement of the touch electrodes.

[0075] In some embodiments, the pressure relief section 32 is disposed on a different layer from the touch layer 50. In other embodiments, the pressure relief section 32 may be disposed on the same layer as the touch layer 50. Specifically, the touch layer 50 includes touch traces disposed in the non-display area NAA, and the pressure relief section 32 and the touch traces are spaced apart.

[0076] Based on the same inventive concept, this application also provides a display device, which includes the display panel 100 in the above embodiments.

[0077] Thus, when the display panel 100 is subjected to external high voltage or electrostatic shock, a discharge effect can be generated at the discharge tip 311 of the transmission section 31, and the high voltage or electrostatic voltage can be quickly absorbed and conducted to the connection end 312 through the transmission section 31, and then discharged to the outside through the connection end 312, thereby reducing damage to the array substrate and device layer of the display substrate 10 and improving the service life of the display panel 100.

[0078] When using the terms “including,” “having,” and “comprising” as described herein, another component may be added unless explicitly qualifying terms such as “only,” “consisting of,” etc. are used. Unless otherwise stated, singular terms may include plural forms and should not be construed as having a quantity of one.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
