Description

Technical Field

[0001] The present application relates to the field of display technologies, and particularly to a display panel, a display module, and a display terminal. Background Art

[0002] The fifth-generation mobile communication technology (5G) is the latest generation of cellular mobile communication technology. Compared with 4G technology, 5G has advantages such as higher data transmission speed, wider bandwidth, stronger reliability, and lower time delay.

[0003] However, for antennas, the upgrade of communication technology is not a product replacement but a sharp increase in the number of antennas. The sharp increase in the number of antennas leads to an increase in the space required to place the antennas. Conventional antennas are usually installed on the back cover or the middle frame of the display terminal, which is contrary to the current mainstream pursuit of ultra-thin and ultra-narrow display products. Summary of the Invention

[0004] Based on this, it is necessary to provide a display panel, a display module, and a display terminal that can design more antennas in a limited space.

[0005] According to one aspect of the present application, a display panel is provided, including a display area and a border area surrounding at least part of the display area. The border area includes a bonding area and an upper border area disposed opposite to the bonding area. The display panel includes:

[0006] A substrate; and

[0007] A multi-layer metal layer disposed on one side of the substrate;

[0008] Wherein, at least one metal layer located in the upper border area is disconnected from the metal layer in other areas of the border area to form an antenna structure.

[0009] For the above display panel, separating the metal layer in the upper border area as an antenna structure not only provides space for the antenna, but also requires less modification to the structure of the existing panel. In addition, the stability of the antenna structure can also be improved.

[0010] In one embodiment, the metal layer forming the antenna structure is disconnected or connected to an adjacent metal layer in the upper border area. When the metal layer forming the antenna structure is disconnected from an adjacent metal layer in the upper border area, it is to avoid the adjacent metal layer affecting the formation of the antenna structure by this metal layer in the upper border area. When the metal layer forming the antenna structure is connected to an adjacent metal layer in the upper border area, it means that the adjacent metal layer has no influence on the formation of the antenna structure by this metal layer in the upper border area.

[0011] In one embodiment, the multi-layer metal layer includes a wiring layer, an anode layer, and a cathode layer which are stacked. The metal layer forming the antenna structure is at least one of the wiring layer, the anode layer, and the cathode layer. Using them as the antenna structure can avoid adding a new metal layer in the border area, thus simplifying the manufacturing process and saving the manufacturing cost.

[0012] In one embodiment, when the metal layer forming the antenna structure is the cathode layer, the cathode layer includes a first part and a second part. The first part is located in the upper border area, and the second part is located in the display area;

[0013] The first part and the second part are disconnected, and the first part and the anode layer are disconnected in the upper border area. In the traditional technology, the cathode layer is usually formed by integral evaporation plating. Therefore, in order to form the antenna structure, the part in the upper border area needs to be separated from the whole. Therefore, the part in the upper border area forming the antenna structure needs to be disconnected from the part in the display area. And since the cathode layer obtains the cathode potential by bridging the wiring layer through the anode layer, in order to form the antenna structure, the cathode layer located in the upper border area also needs to be disconnected from the anode layer to avoid obtaining the cathode potential.

[0014] In one embodiment, when the metal layer forming the antenna structure is the anode layer, the anode layer located in the upper border area is disconnected from the cathode layer located in the upper border area. It can avoid the cathode potential of the wiring layer being bridged to the cathode layer through the anode layer in the upper border area to obtain the cathode potential, thereby affecting the formation of the antenna structure.

[0015] In one embodiment, when the metal layer forming the antenna structure is the anode layer, the anode layer located in the upper border area is disconnected from the wiring layer located in the upper border area. It can avoid the cathode potential of the wiring layer being bridged to the cathode layer through the anode layer in the upper border area to obtain the cathode potential, thereby affecting the formation of the antenna structure.

[0016] In one embodiment, when the metal layer forming the antenna structure is the wiring layer, the wiring layer located in the upper border area is connected to the anode layer located in the upper border area. Since the wiring layer has been disconnected between the upper border area and other areas of the border area, the cathode potential cannot be bridged to the cathode layer through the anode layer in the upper border area. Therefore, connecting the wiring layer located in the upper border area to the anode layer located in the upper border area does not affect the formation of the antenna structure by the wiring layer in the upper border area. In addition, since the disconnection method is simple, the manufacturing process is also simplified.

[0017] In one embodiment, the wiring layer includes a power supply wiring, and the metal layer forming the antenna structure is the power supply wiring. When the voltage drop on the side of the power supply wiring away from the bonding area is large, the power potential accessed from the side of the power supply wiring away from the bonding area to each metal layer has little substantial impact on the entire metal layers. Therefore, the power supply wiring located in the upper border area can be arranged as an antenna structure for use, so that the existing position in the display panel is utilized to place the antenna, increasing the number of antennas without increasing the antenna placement space.

[0018] In one embodiment, the power supply wiring includes an ELVSS power supply wiring. The cathode layer is usually formed by full-surface evaporation coating. In order to make the access of the cathode potential balanced, the overlapping area where the ELVSS power supply wiring overlaps with the anode layer, like the border area BZ, also needs to be arranged around the display area AA, so that the antenna structure can be successfully fabricated and the antenna structure is stable.

[0019] In one embodiment, the border area includes a side border area between the upper border area and the bonding area. The upper border area includes a top border area and a transition border area. The transition border area is located between the top border area and the side border area. The transition border area, like the top border area, has little overall impact on the metal layer.

[0020] According to another aspect of the present application, there is provided a display module including the above-mentioned display panel.

[0021] In the above-mentioned display module, the metal layer in the upper border area is separated as an antenna structure for use, which not only provides a placement space for the antenna, but also requires less modification to the structure of the existing panel. In addition, the stability of the antenna structure can also be improved.

[0022] According to still another aspect of the present application, there is provided a display device including the above-mentioned display module.

[0023] In the above-mentioned display device, the metal layer in the upper border area is separated as an antenna structure for use, which not only provides a placement space for the antenna, but also requires less modification to the structure of the existing panel. In addition, the stability of the antenna structure can also be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] For ease of understanding the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the related listed items.

[0042] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0043] In the description of the embodiments of this application, the orientation or positional relationship indicated by technical terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the embodiments of this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0044] In the description of the embodiments of this application, unless otherwise clearly specified and limited, technical terms such as "connected", "connected to", "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can also be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of this application can be understood according to specific circumstances.

[0045] As described in the background art, with the upgrade of communication technology, the number of antennas has increased sharply, and the existing display terminals are developing towards the mainstream of ultra-thin and ultra-narrow, making it difficult to further expand the installation positions of antennas on display terminals.

[0046] To solve the above problems, various solutions have been proposed in the prior art. One is to remove some touch electrodes or reduce the size of touch electrodes to provide space for placing antenna structures, and the other is to reuse the touch unit or the patterned cathode and anode as antenna structures.

[0047] However, the above two methods involve many modifications to the structure of the existing display panel, and the performance of the antenna itself and the multiplexing structure is unstable.

[0048] Therefore, an embodiment of the present application provides a display panel 100, in which the existing metal layer 20 is disconnected in the upper border area BZ1 and other areas of the border area BZ, so that the metal layer 20 in the upper border area BZ1 serves as the antenna structure 30. Therefore, the existing metal layer 20 is used as the antenna structure 30, which not only provides a placement space for the antenna, but also involves fewer modifications to the structure of the existing panel.

[0049] Figure 1 shows a schematic structural diagram of a display panel in the related art. Refer to Figure 1 It can be seen that the display panel 100 includes a display area AA and a non-display area NA surrounding the display area AA. During the display process of the display panel 100, the image is displayed in the display area AA, and no image is displayed in the non-display area NA.

[0050] The non-display area NA includes a border area BZ. Specifically, the border area BZ includes an upper border area BZ1, a first side border BZ2, a second side border BZ3, and a lower border area BZ4. The first side border BZ2 and the second side border BZ3 are respectively located on both sides of the display area AA along the first direction X, and the upper border area BZ1 and the lower border area BZ4 are located on both sides of the display area AA along the second direction Y. The first direction is perpendicular to the second direction. Specifically, the first direction is the longitudinal direction of the display panel 1, and the second direction is the transverse direction of the display panel 1.

[0051] The lower border area BZ4 includes a bonding area BO, and a plurality of conductive pads are provided in the bonding area BO. The conductive pads are used for electrical connection with electronic components, where the electronic components can be an IC chip or a flexible printed circuit (FPC for short).

[0052] The display panel 100 is an organic light emitting diode (OLED) display panel, which specifically includes a substrate, a thin film transistor (TFT), an anode layer, a display light emitting layer, and a cathode layer stacked along the third direction Z. Among them, the display light emitting layer can emit light under the drive of the anode layer and the cathode layer. Specifically, the first direction, the second direction, and the third direction are perpendicular to each other. More specifically, the third direction is the thickness direction of the display panel 100.

[0053] Figure 2 shows a schematic cross-sectional structure diagram of a display panel in an embodiment of the present application.

[0054] Referring to the accompanying drawings, the display panel 100 of the present application includes a substrate 10 and a multi-layer metal layer 20 disposed on one side of the substrate 10.

[0055] Wherein, at least one layer of the metal layer 20 located in the upper border area BZ1 is disconnected from the metal layer 20 in other areas of the border area BZ to form an antenna structure 30.

[0056] It should be noted that, on the one hand, since the metal layer 20 forming the antenna structure 30 is located in the border area BZ, it does not affect the function of the metal layer 20 in the display area AA. On the other hand, each metal layer 20, whether indirectly or directly, needs to be connected to the conductive pad in the bonding area BO. Since the upper border area BZ1 is far from the bonding area, the obtained potential is relatively low, and the overall impact on the metal layer 20 is small.

[0057] Therefore, in the present application, the metal layer 20 in the upper border area BZ1 is separated as the antenna structure 30 for use, which not only provides a placement space for the antenna, but also has less impact on the structure of the existing panel. In addition, the stability of the antenna structure 30 can also be improved.

[0058] In some embodiments, the metal layer 20 forming the antenna structure 30 is disconnected or connected to an adjacent metal layer 20 in the upper border area BZ1.

[0059] It should be noted that when the metal layer 20 forming the antenna structure 30 is disconnected from an adjacent metal layer 20 in the upper border area BZ1, it is to avoid the adjacent metal layer 20 in the upper border area BZ1 affecting the formation of the antenna structure 30 by this metal layer 20. And when the metal layer 20 forming the antenna structure 30 is connected to an adjacent metal layer 20 in the upper border area BZ1, it means that the adjacent metal layer 20 in the upper border area BZ1 has no influence on the formation of the antenna structure 30 by this metal layer 20. Generally speaking, whether it is disconnected or connected, it is to ensure that the metal layer 20 can form the antenna structure 30.

[0060] Specifically, in some embodiments of the present application, the multi-layer metal layer 20 includes a wiring layer 21, an anode layer 22 and a cathode layer 23 which are stacked, and the metal layer forming the antenna structure 30 is at least one of the wiring layer 21, the anode layer 22 and the cathode layer 23.

[0061] In the traditional technology, at least part of the wiring layer 21, the anode layer 22 and the cathode layer 23 is located in the border area BZ. Therefore, using them as the antenna structure 30 can avoid adding new metal layers in the border area BZ, thus simplifying the manufacturing process and saving the manufacturing cost.

[0062] Further, when the metal layer 20 forming the antenna structure 30 is the cathode layer 23, the cathode layer 20 includes a first part and a second part. The first part is located in the upper border area BZ1, and the second part is located in the display area AA. The first part and the second part are disconnected, and the first part and the anode layer 22 are disconnected in the upper border area BZ1.

[0063] In the prior art, the cathode layer 23 is usually formed by integral evaporation coating. Therefore, in order to form the antenna structure 30, a part of the upper border area BZ1 needs to be separated from the whole. Thus, the upper border area BZ1 forming the antenna structure 30 needs to be disconnected from the part in the display area AA. And since the cathode layer 23 obtains the cathode potential through the anode layer 22 bridging the wiring layer 23, in order to form the antenna structure 30, the cathode layer 23 located in the upper border area BZ1 also needs to be disconnected from the anode layer 22 to avoid obtaining the cathode potential.

[0064] It should also be noted that the disconnection between the first part and the second part can be achieved by using a masking plate with a shielding effect during the evaporation coating process.

[0065] As Figure 3 shown, in some other embodiments, when the metal layer 20 forming the antenna structure 30 is the anode layer 22, the anode layer 22 located in the upper border area BZ1 is disconnected from the cathode layer 23 located in the upper border area BZ1.

[0066] Since the cathode layer 23 obtains the cathode potential through the anode layer 22 bridging the wiring layer 23, in order to form the antenna structure 30 with the anode layer 22 located in the upper border area BZ1, disconnecting the anode layer 22 located in the upper border area BZ1 from the cathode layer 23 located in the upper border area BZ1 can avoid the cathode potential of the wiring layer 23 being bridged to the cathode layer 23 through the anode layer 22 in the upper border area BZ1 to obtain the cathode potential.

[0067] As Figure 4 shown, in still some other embodiments, when the metal layer 20 forming the antenna structure 30 is the anode layer 22, the anode layer 22 located in the upper border area BZ1 is disconnected from the wiring layer 21 located in the upper border area BZ1.

[0068] Similarly, since the cathode layer 23 obtains the cathode potential through the anode layer 22 bridging the wiring layer 23, in order to form the antenna structure 30 with the anode layer 22 located in the upper border area BZ1, disconnecting the anode layer 22 located in the upper border area BZ1 from the wiring layer 21 located in the upper border area BZ1 can avoid the cathode potential of the wiring layer 23 being bridged to the cathode layer 23 through the anode layer 22 in the upper border area BZ1 to obtain the cathode potential.

[0069] As Figure 5As shown, in other embodiments, when the metal layer 20 forming the antenna structure 30 is the trace layer 21, the trace layer 21 located in the upper border area BZ1 is connected to the anode layer 22 located in the upper border area BZ1.

[0070] Since the trace layer 21 has been disconnected between the upper border area BZ1 and other areas of the border area BZ, the cathode potential cannot be bridged to the cathode layer 23 through the anode layer 22 in the upper border area BZ1. Therefore, connecting the trace layer 21 located in the upper border area BZ1 to the anode layer 22 located in the upper border area BZ1 does not affect the formation of the antenna structure 30 by the trace layer 21 in the upper border area BZ1. Additionally, since the disconnection method is simple, the manufacturing process is also simplified.

[0071] Of course, when the metal layer 20 forming the antenna structure 30 is the trace layer 21, the trace layer 21 located in the upper border area BZ1 and the anode layer 22 located in the upper border area BZ1 can also be disconnected, and there is no limitation here.

[0072] In the embodiments of the present application, the trace layer 21 includes a power trace, and the metal layer 20 forming the antenna structure 30 is a power trace.

[0073] One end of the power trace is connected to the conductive pad in the bonding area BO, and the other end overlaps with a part of the metal layer 20 in the border area BZ, and then bridges a part of the metal layer 20 in the display area AA to input a power voltage signal to the corresponding metal layer 20.

[0074] However, due to the influence of loads such as the resistance and capacitance of the line itself during the routing of the power trace, a certain voltage drop will occur, resulting in a decrease in voltage on the side far from the bonding area BO, which will affect the brightness uniformity of the display light-emitting layer.

[0075] Therefore, the power voltage potential accessed from the side of the power trace far from the bonding area BO to the metal layer 20 has little impact on the entire metal layer 20. Therefore, the power trace located in the upper border area BZ1 can be set as the antenna structure 30 for use, making use of the position in the existing display panel 100 to place the antenna, and increasing the number of antennas without increasing the antenna placement space.

[0076] Preferably, the power trace includes an ELVSS power trace.

[0077] The ELVSS power trace is also called a common power trace. One end of it extends to the bonding area BO and is connected to a driving chip (not shown in the figure) in the bonding area BO. The ELVSS power trace is connected to the cathode layer 23 and is used to transmit the power voltage signal ELVSS to the cathode layer 34.

[0078] Specifically, one end of the ELVSS power trace is connected to the conductive pad of the bonding area BO, and the other end is overlapped with the anode layer 22 within the border area BZ, and then bridges the cathode layer 23 within the display area AA to input a power voltage signal to the cathode layer 23.

[0079] The cathode layer 23 is usually formed by full-surface evaporation coating. In order to make the cathode potential access balanced, the overlapping area where the ELVSS power trace overlaps with the anode layer 22, like the border area BZ, needs to be arranged around the display area AA. Therefore, the antenna structure can be successfully fabricated and the antenna structure is stable.

[0080] It should also be noted that the power trace of the present application is arranged on the same layer as the drain 50 and the source 60 of the display area AA.

[0081] In all the above embodiments, the so-called disconnection setting means that the corresponding metal layers 20 are disconnected through an insulating material. For example, the trace layer 21 located in the upper border area BZ1 and the anode layer 22 located in the upper border area BZ1 are isolated by a planarization layer 70 for disconnection setting, and the anode layer 23 located in the upper border area BZ1 and the anode layer 22 located in the upper border area BZ1 are isolated by a pixel definition layer 80 for disconnection setting.

[0082] In some embodiments, the upper border area BZ1 includes a top border area and a transition border area, and the transition border area is located between the top border area and the side border area. In practical applications, the potential supply mainly comes from the metal layer 20 of the side border area, and this transition border area, like the top border area, has little overall impact on the metal layer 20. The transition border area of the present application is arc-shaped, specifically, it can be a quarter arc-shaped, and the top border area of the present application is rectangular.

[0083] Specifically, the side border area can be at least one of the first side border area BZ2 and the second side border area BZ3. Correspondingly, the transition border area includes at least one of the first transition border area and the second transition border area. The first transition border area is connected between the upper border area BZ1 and the first side border area BZ2, and the second transition border area is connected between the upper border area BZ1 and the second side border area BZ6.

[0084] Therefore, the formation position of the antenna structure 30 can be adjusted according to requirements. For example, the antenna structure 30 is formed in the first transition border area or the second transition border area. In other embodiments, the antenna structure 30 can also be formed in the first transition border area and the top border area, or the antenna structure 30 can also be formed in the second transition border area and the top border area, or even formed in the first transition border area, the second transition border area and the top border area.

[0085] Based on the same inventive concept, the present application also provides a display module, including the above-mentioned display panel 100.

[0086] The display module may further include a polarizer, a touch screen, and a cover plate laminated above the display panel 100.

[0087] In the display module of the present application, the existing metal layer 20 is disconnected in the upper border area BZ1 and other areas of the border area BZ, so that the metal layer 20 in the upper border area BZ1 serves as the antenna structure 30. Therefore, the existing metal layer 20 is used as the antenna structure 30, which not only provides a placement space for the antenna, but also requires less modification to the structure of the existing panel.

[0088] Based on the same inventive concept, the present application also provides a display terminal including the above-mentioned display module.

[0089] Specifically, the display terminal can be applied to fields such as mobile phone terminals, bionic electronics, electronic skin, wearable devices, vehicle-mounted devices, Internet of Things devices, and artificial intelligence devices. The display terminal can specifically be digital devices such as mobile phones, tablets, palm computers, iPods, smart watches, etc.

[0090] In the display terminal of the present application, the existing metal layer 20 is disconnected in the upper border area BZ1 and other areas of the border area BZ, so that the metal layer 20 in the upper border area BZ1 serves as the antenna structure 30. Therefore, the existing metal layer 20 is used as the antenna structure 30, which not only provides a placement space for the antenna, but also requires less modification to the structure of the existing panel.

[0091] In cases where "including", "having", and "comprising" described in this article are used, unless explicit limiting terms such as "only", "consisting of", etc. are used, another component can also be added. Unless otherwise mentioned, terms in the singular form can include the plural form and should not be understood as having a quantity of one.

[0092] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0093] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
