DETAILED DESCRIPTION

[0048] The following detailed description and drawings of the embodiments of the present application are used to illustrate the principles of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described embodiments.

[0049] In the description of the present application, it should be noted that, unless otherwise specified, "multiple" means more than two; the terms "upper", "lower", "left", "right", "inside", "outside", etc., indicating the orientation or positional relationship, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. "Vertical" is not strictly vertical, but is within the allowable error range. "Parallel" is not strictly parallel, but is within the allowable error range.

[0050] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0051] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0052] With the evolution of mobile communication technology and the coexistence of multiple networks, the number of antenna electrodes in display panels and the frequency bands they need to support are increasing. At the same time, due to the significant increase in the screen-to-body ratio of display panels, the area in the display panel that can be used to lay out antenna electrodes is further compressed, which affects the performance of the antenna electrodes and the quality of wireless communication. At present, the antenna electrodes can be integrated into the display panel to reduce or avoid blocking of the antenna electrodes to improve communication functions. However, since the antenna electrodes are usually attached to the outside of the encapsulation layer of the display panel, they can be designed with the same film layer as the touch layer of the panel, making the display panel prone to moiré, diffraction, and granularity, which affects the display effect. At the same time, the antenna electrodes also occupy the touch space, affecting the touch performance.

[0053] In view of this, the present application provides a display panel and a display device to solve the above problems. The display panel provided by the present application is first introduced below.

[0054] See also Figure 1 and Figure 2 In a first aspect, the present application provides a display panel, including an array substrate 10 and a light-emitting unit 30, including a substrate 11 and an array layer 12, wherein the array layer 12 is arranged on one side of the substrate 11, and includes a driving circuit 13 and an antenna electrode 14, wherein the driving circuit 13 is used to drive the light-emitting unit 30 to emit light, and an orthographic projection of at least part of the antenna electrode 14 on the substrate 11 is staggered with an orthographic projection of the driving circuit 13 on the substrate 11.

[0055] The display panel provided in the embodiment of the present application can be an organic light emitting diode (OLED) display panel, and the display panel can also be other types of display panels, such as a micro light emitting diode (Micro Light Emitting Diode, Micro-LED for short) or a quantum dot light emitting diode (Quantum Light Emitting Diode, QLED for short) display panel.

[0056] The substrate 11 may be a rigid substrate 11 made of materials such as glass or plastic, or a flexible substrate 11 made of materials such as polyethersulfone (PES), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyarylate, polyimide (PI), polycarbonate (PC) or cellulose acetate propionate (CAP). The array layer 12 is arranged on one side of the substrate 11, and includes a driving circuit 13 and an antenna electrode 14. The driving circuit 13 is used to control the light emission of the light-emitting unit 30 in the display panel. It is generally composed of film layers such as a metal layer and a semiconductor layer (active layer). The circuit structure of the driving circuit 13 has multiple implementation methods, which are not limited in this embodiment. In addition, the array layer 12 may also include an insulating layer for implementing the insulation of each metal layer and semiconductor layer 19 in the array layer 12. It should be noted that the antenna electrode 14 of the present application has the function of transmitting data outwardly and receiving external data, that is, the antenna electrode 14 can be used as a transmitting antenna when data needs to be transmitted outwardly, and can also be used as a receiving antenna when external data needs to be received.

[0057] In the embodiment of the present application, the antenna electrode 14 is integrated in the array layer 12 of the array substrate 10. Compared with the antenna electrode 14 being located in the touch layer, the risk of the display panel generating moiré, diffraction and graininess can be reduced, and the antenna electrode 14 can be prevented from occupying the touch space and affecting the touch effect, thereby improving the performance of the display panel. In addition, the orthographic projection of at least part of the antenna electrode 14 on the substrate 11 is staggered with the orthographic projection of the drive circuit 13 on the substrate 11, thereby preventing the drive circuit 13 from completely blocking the antenna electrode 14 and affecting the data transmission function of the antenna electrode 14, thereby ensuring the normal operation of the antenna electrode 14.

[0058] In some optional embodiments, the shape of the antenna electrode 14 may be a regular shape such as a prism, a square, a rectangle, or other irregular shapes, which is not limited in this embodiment.

[0059] Furthermore, there may be multiple antenna electrodes 14, which are arranged at intervals and are not connected to each other. The data transmission capacity of the display panel can be improved by transmitting data through multiple antenna electrodes 14. It should be noted that the shapes and sizes of the multiple antenna electrodes 14 can be the same or different, and this embodiment does not limit this.

[0060] See also Figure 2 In some embodiments, the driving circuit 13 includes a first metal layer 15, a second metal layer 16, a third metal layer 17 and a fourth metal layer 18 stacked in a direction away from the substrate 11, and at least one of the first metal layer 15, the second metal layer 16, the third metal layer 17 and the fourth metal layer 18 is arranged in the same layer as the antenna electrode 14 to reduce the thickness of the array substrate 10.

[0061] It should be noted that the number of antenna electrodes 14 can be multiple, and at least one of the first metal layer 15, the second metal layer 16, the third metal layer 17 and the fourth metal layer 18 can be arranged in the same layer as the multiple antenna electrodes 14. For example, the multiple antenna electrodes 14 can be arranged in the same layer as the third metal layer 17, or the multiple antenna electrodes 14 can be arranged in the same layer as the fourth metal layer 18, or a part of the multiple antenna electrodes 14 can be arranged in the same layer as the third metal layer 17, and another part can be arranged in the same layer as the fourth metal layer 18, or a part of the multiple antenna electrodes 14 can be arranged in the same layer as the fourth metal layer 18, and another part can be arranged in the same layer as the second metal layer 16, and this embodiment does not limit this.

[0062] It can be understood that when the driving circuit 13 includes a first metal layer 15, a second metal layer 16, a third metal layer 17 and a fourth metal layer 18, the orthographic projection of at least part of each antenna electrode 14 on the substrate 11 is staggered with the orthographic projection of the first metal layer 15, the second metal layer 16, the third metal layer 17 and the fourth metal layer 18 on the substrate 11, thereby avoiding the first metal layer 15, the second metal layer 16, the third metal layer 17 and the fourth metal layer 18 blocking the antenna electrode 14 from transmitting data.

[0063] Preferably, at least one of the first metal layer 15 , the second metal layer 16 , the third metal layer 17 and the fourth metal layer 18 is made of the same material as the antenna electrode 14 .

[0064] In these embodiments, when at least one of the first metal layer 15, the second metal layer 16, the third metal layer 17 and the fourth metal layer 18 is arranged in the same layer as the antenna electrode 14, the material of the antenna electrode 14 is also the same as the material of the metal layer in the same layer. Therefore, in the preparation process of the array substrate 10, the antenna electrode 14 can be made with the metal layer in the same layer using the same process to simplify the process steps and reduce costs.

[0065] It should be noted that, in the preparation process of at least one of the first metal layer 15, the second metal layer 16, the third metal layer 17 and the fourth metal layer 18, a metal material layer can be first formed by a physical vapor deposition process, and then the metal material layer can be patterned by exposure, dry etching, stripping and other processes to form a metal layer and an antenna electrode 14 with a preset shape.

[0066] Optionally, at least one of the first metal layer 15, the second metal layer 16, the third metal layer 17 and the fourth metal layer 18 may include at least one of metal materials such as copper, molybdenum, titanium, aluminum, etc., or may also include a stacked structure formed by at least two of the aforementioned metal materials. For example, at least one of the first metal layer 15, the second metal layer 16, the third metal layer 17 and the fourth metal layer 18 may include a Ti / Al / Ti stacked structure.

[0067] Preferably, the first metal layer 15 includes a gate 151, the second metal layer 16 includes a capacitor plate 161, and the third metal layer 17 includes a source 171 and a drain 172. That is, the antenna electrode 14 can be manufactured using the same process as at least one of the gate 151, the capacitor plate 161, the source 171 and the drain 172 to simplify the process steps.

[0068] In addition, the driving circuit 13 further includes a semiconductor layer 19 , and a source electrode 171 and a drain electrode 172 are respectively overlapped with the semiconductor layer 19 to form a thin film transistor to control the light emitting unit 30 to emit light.

[0069] Please continue reading Figure 2 Preferably, the display panel further includes a light emitting unit 30 , which is disposed on one side of the array substrate 10 , and includes a first electrode 31 , a light emitting functional layer 32 , and a second electrode 33 stacked in a direction away from the array substrate 10 .

[0070] The light-emitting unit 30 is arranged on one side of the array substrate 10, wherein the first electrode 31, the light-emitting functional layer 32 and the second electrode 33 are stacked in a direction away from the array substrate 10, that is, the first electrode 31 is located on the side of the light-emitting functional layer 32 facing the array substrate 10, and the second electrode 33 is located on the side of the light-emitting functional layer 32 away from the array substrate 10. One of the first electrode 31 and the second electrode 33 can be used as the anode of the light-emitting unit 30, and the other as the cathode of the light-emitting unit 30. In the embodiment of the present application, the first electrode 31 is used as the anode of the light-emitting unit 30, and the second electrode 33 is used as the cathode of the light-emitting unit 30. It should be noted that the light-emitting functional layer 32 can be formed by stacking a plurality of film layer structures. For example, the light-emitting functional layer 32 can include a stacked hole injection layer (HIL), a hole transport layer (HTL), a light-emitting layer, an electron injection layer (EIL) and an electron transport layer (ETL).

[0071] Preferably, the fourth metal layer 18 includes a connecting electrode 181 , and the connecting electrode 181 is connected to the drain electrode 172 and the first electrode 31 of the light emitting unit 30 , respectively.

[0072] Specifically, the connection electrode 181 is located between the drain electrode 172 and the first electrode 31, and can be connected to the drain electrode 172 and the first electrode 31 through vias, respectively. Compared with setting the drain electrode 172 to be directly connected to the first electrode 31 through vias, the depth of a single via can be reduced, and the difficulty of making the vias can be reduced. In addition, the antenna electrode 14 can be made with the connection electrode 181 using the same process to simplify the process steps.

[0073] In some embodiments, Figure 2 As shown, the antenna electrode 14 and the third metal layer 17 are in the same layer and are made of the same material; and / or, as Figure 3 As shown, the antenna electrode 14 and the fourth metal layer 18 are provided in the same layer and with the same material.

[0074] In these embodiments, the antenna electrode 14 is provided in the same layer and material as the third metal layer 17 and / or the fourth metal layer 18 , and is closer to the external environment than the first metal layer 15 and the second metal layer 16 , so as to facilitate data transmission.

[0075] Preferably, the material of the antenna electrode 14 includes at least one of molybdenum, copper, aluminum, and titanium, so that the material of the antenna electrode 14 is reasonably set to improve the performance of the antenna electrode 14.

[0076] It should be noted that the antenna electrode 14 may include one or more of the above materials. When the antenna electrode 14 includes multiple of the above materials, the antenna electrode 14 may be a laminated structure formed by laminating the multiple materials. For example, the antenna electrode 14 may be a titanium-aluminum-titanium laminated structure. It can be known that when the material of the antenna electrode 14 includes the above materials, the third metal layer 17 and / or the fourth metal layer 18 are in the same layer and made of the same material as the antenna electrode 14, and thus also include the above materials.

[0077] See also Figure 4 In some embodiments, the array layer 12 further includes an auxiliary electrode 20, which is used to be connected to the negative power supply voltage and the second electrode 33 of the light-emitting unit 30, respectively, so that the second electrode 33 is electrically connected to the negative power supply voltage through the auxiliary electrode 20, which can improve the electron injection efficiency of the second electrode 33 and enhance the performance of the display panel.

[0078] Preferably, at least one of the first metal layer 15, the second metal layer 16, the third metal layer 17 and the fourth metal layer 18 is in the same layer and is made of the same material as the auxiliary electrode 20. Therefore, at least one of the first metal layer 15, the second metal layer 16, the third metal layer 17 and the fourth metal layer 18 can be made using the same process as the auxiliary electrode 20 to simplify the process steps and save costs.

[0079] Preferably, the auxiliary electrode 20 is in the same layer and made of the same material as the fourth metal layer 18, which can shorten the distance between the auxiliary electrode 20 and the second electrode 33 of the light-emitting unit 30. When the two are connected through a via, the depth of the via can be reduced, thereby reducing the difficulty of preparing the via.

[0080] It should be noted that when the auxiliary electrode 20 and the antenna electrode 14 are both in the same layer and made of the same material as the fourth metal layer 18 , the material of the auxiliary electrode 20 is the same as that of the antenna electrode 14 .

[0081] Preferably, the first electrode 31 is an anode and the second electrode 33 is a cathode. The second electrode 33 can inject electrons into the light-emitting functional layer 32, and the first electrode 31 can inject holes into the light-emitting functional layer 32. The electrons and holes combine in the light-emitting functional layer 32, thereby exciting the light-emitting functional layer 32 to emit light.

[0082] Preferably, the auxiliary electrode 20 is an auxiliary cathode, which can help improve the electron injection efficiency of the second electrode 33 and further improve the light-emitting effect of the display panel.

[0083] Please continue reading Figure 4 In some embodiments, the array substrate 10 further includes a planarization layer 21, which is disposed on a side of the array layer 12 facing away from the substrate 11, so that the surface of the array substrate 10 is flat, so as to facilitate the subsequent preparation of the light-emitting unit 30 on the array substrate 10, thereby improving the yield of the light-emitting unit 30.

[0084] Optionally, the material of the planarization layer 21 may include organic materials such as polyimide, polyethylene terephthalate, polycarbonate PC, polyethylene or polyacrylate PAR. The thickness, material, and film forming process of the planarization layer 21 can be set by those skilled in the art according to actual conditions and are not limited here.

[0085] See also Figure 5 Preferably, the display panel also includes a pixel definition layer 40, which is arranged on the side of the planarization layer 21 away from the substrate 11. The pixel definition layer 40 includes a pixel defining portion 41 and a pixel opening 42 formed by the pixel defining portion 41. The light-emitting unit 30 is arranged in the pixel opening 42 to achieve insulation of each light-emitting unit 30 through the pixel defining portion 41, thereby reducing crosstalk between each light-emitting unit 30 and improving the display effect of the display panel.

[0086] Preferably, the planarization layer 21 and the pixel defining portion 41 are provided with a first via hole 22, which exposes at least a portion of the auxiliary electrode 20, for allowing the second electrode 33 to overlap with the auxiliary electrode 20, so as to be indirectly connected to the negative power supply voltage through the auxiliary electrode 20, so that the light-emitting unit 30 can emit light normally.

[0087] Please continue reading Figure 5 Preferably, the display panel further comprises a conductive portion 50, the conductive portion 50 is located in the first via hole 22, and the conductive portion 50 is electrically connected to the second electrode 33 and the auxiliary electrode 20, respectively. The second electrode 33 is electrically connected to the auxiliary electrode 20 through the conductive portion 50. After the first electrode 31 and the light-emitting functional layer 32 of the light-emitting unit 30 are prepared, a first via hole 22 may be formed in the pixel defining portion 41 and the planarization layer to expose the auxiliary electrode 20, and then the conductive portion 50 is prepared in the first via hole 22, so that the conductive portion 50 overlaps the auxiliary electrode 20, and then the second electrode 33 is prepared on the side of the pixel defining portion 41 away from the array substrate 10, so that the second electrode 33 is electrically connected to the conductive portion 50.

[0088] Preferably, the material of the conductive part 50 includes at least one of titanium, aluminum and copper to ensure its conductive performance.

[0089] It should be noted that the conductive part 50 may include one or more of the above-mentioned materials. When the conductive part 50 includes multiple of the above-mentioned materials, the conductive part 50 may be a stacked structure formed by stacking the above-mentioned multiple materials. For example, the conductive part 50 may be a titanium-aluminum stacked structure or a titanium-copper stacked structure.

[0090] Optionally, the material of the conductive portion 50 may be the same as that of the second electrode 33 , and the two may be manufactured using the same process to simplify the process steps.

[0091] Optionally, the cross-sectional shape of the conductive portion 50 along the thickness direction of the substrate 11 may be an inverted trapezoidal shape to facilitate preparation.

[0092] Please continue reading Figure 4 and Figure 5 Preferably, the planarization layer 21 is provided with a second via hole 23, which exposes at least a portion of the connecting electrode 181, and is used for the first electrode 31 to overlap with the connecting electrode 181, so as to be indirectly connected to the drain 172 of the driving circuit 13 through the connecting electrode 181, so that the light-emitting unit 30 can emit light normally.

[0093] See also Figure 6 In some embodiments, the display panel includes a display area AA and a non-display area NA at least located on one side of the display area AA, and the antenna electrode 14 is at least located in the non-display area NA.

[0094] In these embodiments, since the metal structures in the non-display area NA (such as metal wiring in the driving circuit 13, electrodes in the light-emitting unit 30, etc.) are less than those in the display area AA, the antenna electrode 14 is arranged to be at least located in the non-display area NA, which can reduce the risk of the above metal structure completely blocking the antenna electrode 14, so as to ensure that the antenna electrode 14 can work normally. At the same time, the antenna electrode 14 is at least located in the non-display area NA, which can also reduce its space occupation in the display area AA and improve the space utilization rate of the display area AA.

[0095] In addition, when the antenna electrode 14 is connected to the RF chip 60 through a conductive wire, setting the antenna electrode 14 at least in the non-display area NA can also facilitate leading out the conductive wire, shorten the length of the conductive wire, and avoid interference between the conductive wire and the metal film layer in the driving circuit 13 of the display area AA.

[0096] Preferably, the antenna electrode 14 is also located in the display area AA, so that the number of the antenna electrodes 14 can be increased to improve the data transmission capability of the display panel.

[0097] Preferably, the antenna electrode 14 in the display area AA is disposed close to the non-display area NA, so that the antenna electrode 14 in the display area AA can transmit data easily. Furthermore, when the antenna electrode 14 is electrically connected to the RF chip 60 through a conductive wire, the antenna electrode 14 in the display area AA is disposed close to the non-display area NA, so that the conductive wire corresponding to the antenna electrode 14 in the display area AA can be easily led out.

[0098] Preferably, the non-display area NA is disposed around the display area AA, so that the antenna electrode 14 in the non-display area NA can transmit data from various locations in the display area AA along the circumferential direction.

[0099] Please continue reading Figure 5 In some embodiments, the display panel further includes a light-emitting unit 30, which is disposed on one side of the array substrate 10, and the orthographic projection of at least part of the antenna electrode 14 on the substrate 11 is offset from the orthographic projection of the light-emitting unit 30 on the substrate 11 to prevent the light-emitting unit 30 from completely blocking the antenna electrode 14 and affecting the data transmission function of the antenna electrode 14.

[0100] Preferably, the light-emitting unit 30 includes a first electrode 31, a light-emitting functional layer 32 and a second electrode 33 which are stacked in a direction away from the array substrate 10, and the orthographic projection of at least part of the antenna electrode 14 on the substrate 11 is offset from the orthographic projection of the first electrode 31 and / or the second electrode 33 on the substrate 11, thereby avoiding the first electrode 31 and / or the second electrode 33 completely covering the antenna electrode 14.

[0101] Preferably, there are multiple light-emitting units 30, and the second electrodes 33 of the light-emitting units 30 are electrically connected to each other to form a full-surface electrode, so that the potential of the second electrodes 33 of the light-emitting units 30 is the same, thereby facilitating control.

[0102] It should be noted that after the second electrodes 33 of each light-emitting unit 30 are electrically connected to each other, the second electrode 33 can be in a grid shape, and the antenna electrode 14 can be located in the grid, so that the orthographic projection of the antenna electrode 14 on the substrate 11 is misaligned with the orthographic projection of the second electrode 33 on the substrate 11, thereby avoiding the second electrode 33 from blocking the antenna electrode 14 and reducing the interference of the second electrode 33 on the antenna electrode 14.

[0103] Please continue reading Figure 5 In some embodiments, the display panel further includes a pixel definition layer 40 , the pixel definition layer 40 includes a pixel defining portion 41 and a pixel opening 42 formed by the pixel defining portion 41 , and the light emitting unit 30 is disposed in the pixel opening 42 .

[0104] In these embodiments, the pixel defining portion 41 encloses a pixel opening 42, and the light-emitting unit 30 is located in the pixel opening 42, so that the light-emitting units 30 are insulated by the pixel defining portion 41, thereby reducing crosstalk between the light-emitting units 30 and improving the display effect of the display panel.

[0105] It should be noted that the insulation of each light-emitting unit 30 achieved through the pixel defining portion 41 can be achieved by insulating the first electrodes 31 of each light-emitting unit 30 through the pixel defining portion 41, and by isolating the pixel defining portion 41 to achieve insulation between the light-emitting functional layers 32 of each light-emitting unit 30. Of course, the second electrodes 33 of each light-emitting unit 30 can also be insulated through the pixel defining portion 41, or the second electrodes 33 of each light-emitting unit 30 can also be connected to each other to form a full-surface electrode, which is not limited in this embodiment.

[0106] Please continue reading Figure 5 Preferably, the orthographic projection of the antenna electrode 14 on the substrate 11 is located between the orthographic projections of two adjacent pixel openings 42 on the substrate 11, that is, the antenna electrode 14 is located between two adjacent light-emitting units 30, and its orthographic projection on the substrate 11 is completely misaligned with the orthographic projection of the light-emitting unit 30 on the substrate 11, thereby avoiding the light-emitting unit 30 from blocking the antenna electrode 14.

[0107] It should be noted that, in the above embodiment, the antenna electrode 14 is located in the display area AA, and it can be disposed close to the non-display area NA, or close to the center of the display area AA, which is not limited in this embodiment.

[0108] See also Figure 7 In some embodiments, the display panel also includes a RF chip 60, which is connected to the antenna electrode 14, so that the signal generated by the RF chip 60 can be transmitted outward via the antenna electrode 14, or the external signal received by the antenna electrode 14 can be transmitted to the RF chip 60.

[0109] Preferably, the RF chip 60 is arranged on the side of the substrate 11 away from the array layer 12. Compared with arranging the RF chip 60 in the non-display area NA, it is beneficial to reduce the area of ​​the non-display area NA and further increase the screen-to-body ratio of the display panel.

[0110] Optionally, the RF chip 60 may be attached to the side of the substrate 11 facing away from the array layer 12 by means of glue to facilitate assembly.

[0111] Preferably, the RF chip 60 and the antenna electrode 14 are connected by coupling induction instead of by conductive wires, which can improve the corresponding speed and data transmission efficiency and reduce costs. In addition, the RF chip 60 and the antenna electrode 14 are connected by coupling induction instead of by transmission lines, which can also avoid the increase of the frame of the display panel due to the setting of the transmission line, which is conducive to realizing a narrow frame of the display panel.
