Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

One or more embodiments of the present invention will be described in detail with reference to the accompanying drawings, in which elements such as shapes, sizes, proportions, angles, and numbers of elements are merely examples, and in different embodiments, the same or corresponding elements may be denoted by the same reference numerals, and repeated descriptions thereof will be omitted.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

When an element such as a layer, film, or substrate is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present, unless otherwise specified. Further, when a layer is referred to as being "under" another layer, it can be directly under, or one or more intervening layers may also be present. It will also be understood that when a layer is referred to as being "between" two layers, it can be the only layer between the two layers, or one or more intervening layers may also be present.

Where the terms "comprising," having, "and" including "are used herein, another element may be added unless a specific limiting term is used, such as" only, "" consisting of 8230 \8230; "consisting of", etc. Unless mentioned to the contrary, terms in the singular may include the plural and are not to be construed as being one in number.

Furthermore, the drawings are not 1:1, and the relative sizes of the various elements in the drawings are drawn for illustration only and not necessarily to true scale.

As mentioned in the background, the network speed of the '5G' mobile communication technology of the fifth generation can reach 5M/S-6M/S. The millimeter wave is electromagnetic wave with wavelength of 1-10 mm, and has the wavelength range in the overlapping area of microwave and far infrared wave and the features of both microwave and far infrared wave. For users, due to the large bandwidth caused by the high working frequency of the millimeter waves, the millimeter waves can achieve high-speed data transmission, are beneficial to the 5G peak data transmission rate of 10-20 Gbps, and have remarkably better wireless experience for applications such as AR, VR, AI, UHD (ultra high definition) image transmission and the like.

However, existing 5G millimeter wave antenna schemes typically have multiple antenna elements and are packaged with a feed network into an antenna module that occupies a certain three-dimensional size. Therefore, the 5G antenna is complex in design and large in number, and the traditional mobile phone antenna installation mode is limited in installation space and cannot be applied to a 5G mobile phone. The inventor researches and discovers that the traditional antenna installation mode ignores the installation space of other parts of the mobile phone, and arranges the antenna at the other parts of the mobile phone, for example, technicians try to increase the antenna arrangement area in the back shell, the middle shell and the upper and lower frames of the display terminal to arrange more antennas so as to meet the requirement of the 5G technology. However, in experiments, if the antenna layout areas in the back shell, the middle shell, and the upper and lower frames are increased, although more antennas can be arranged, the arrangement space of other devices is compressed at the same time, so that the structures and the arrangement modes of other devices need to be modified, thereby significantly increasing the design and production costs. In addition, the structure and the processing technology of other components and the communication quality of the antenna need to be considered, and the layout difficulty of the 5G antenna is further increased.

Therefore, it is necessary to provide a display module and a display terminal having an antenna arrangement space inside a terminal device.

Fig. 1 is a schematic cross-sectional view illustrating a display module according to an embodiment of the invention. For the purpose of illustration, the drawings show only the structures associated with embodiments of the invention.

Referring to the drawings, the display module 100 includes a display panel 10, a flexible connecting member 20, and a heightening structure 30.

In the embodiment of the application, the display module 100 includes a display area and a non-display area surrounding the display area, the display area has a display function, and the non-display area may not have the display function.

The display panel 10 includes a substrate 11, a device layer 12, and an encapsulation structure, which are stacked. Wherein the device layer 12 is located in the display area.

The substrate 11 may be glass or other organic material having elasticity and ductility, such as Polyimide (PI). For example, thermoplastic Polyurethane (TPU) materials have good tensile resistance and also have good resistance to water and oxygen.

Device layers 12 include, but are not limited to: a driving layer group and a light emitting element. Specifically, the light emitting element includes at least an anode, a light emitting layer, and a cathode, and a Thin Film Transistor (TFT) and a wire are contained in a driving layer group to control emission of each light emitting element, or the amount of emission at the time of emission of each light emitting element can be controlled.

The encapsulation structure is disposed on the substrate 11, and is used to prevent the light emitting element from being affected by external environment, and reduce the degradation of the OLED device caused by moisture and oxygen. Optionally, the package structure may be a thin film package layer, or may be a package cover plate.

The display panel 10 may further include a cover plate for protecting the display panel 10 and other structural layers of the display module 100. The cover plate may be made of glass, sapphire, polyvinyl chloride (PVC), etc.

In addition, the display panel 10 further includes a touch layer, a polarizer and other functional layers, an adhesive layer and the like between the package structure and the cover plate. In some embodiments, the cover plate may be a touch-integrated cover plate.

The display panel 10 has a bonding area, and one end of the flexible connecting member 20 is connected to the bonding area, and the other end can be bent along a side away from the light emitting surface of the display panel 10.

It should be noted that the display panel 10 has a light emitting surface and a backlight surface that are oppositely disposed. Specifically, the light emitting element is classified into a top emission type and a bottom emission type according to a difference in light transmission characteristics between a bottom electrode and a top electrode of the light emitting element. In this application, the top electrode of the light emitting element may be a transparent electrode, the bottom electrode may be a reflective electrode, and light emitted by the light emitting element is directly emitted from the top electrode or emitted from the top electrode after being reflected by the bottom electrode, so that a light emitting surface is formed on a surface of one side of the package structure away from the device layer 12, and a backlight surface is formed on a side of the substrate 11 away from the device layer 12.

In the embodiment of the present application, the Flexible connection member 20 is a Chip On Film (COF) or a Flexible Printed Circuit (flexile Printed Circuit), and the Flexible connection member 20 is bent to the backlight surface of the substrate 11, so as to reduce the frame of the display module 100 and improve the screen occupation ratio.

It should be understood that the bonding area should have a first connection terminal, specifically, a first connection terminal on the substrate 11, the first connection terminal being a pad, and the first connection terminal being connectable with a signal line on the display module 100, for example, a data line, a clock signal line, a power line, etc. The flexible connecting element 20 is provided with a second connecting terminal, which is a pad and is also commonly referred to as a gold finger, and the second connecting terminal of the flexible connecting element 20 is connected to the first connecting terminal in a bonding manner, for example, the second connecting terminal is connected to the first connecting terminal through an anisotropic conductive adhesive. The flexible connecting piece 20 is provided with a driving chip, or the flexible connecting piece 20 is provided with the other end opposite to the second connecting terminal and connected with a circuit board provided with the driving chip, the circuit on the flexible connecting piece 20, the second connecting terminal and the first connecting terminal on the substrate 11 realize the electric connection of the display module 100 and the driving chip, so that a driving signal output by the driving chip can be transmitted to the display module 100 to drive the display module 100 to work.

The heightening structure 30 is positioned inside the bent portion of the flexible connection member 20. The raised structure 30 fixes the flexible connector 20 relative to the substrate 11 and also provides support and protection for the driver chip on the flexible connector 20.

In the embodiment of the present application, the heightening structure 30 includes one or any combination of an adhesive layer or an elastic layer. Specifically, the heightening structure 30 may include only two stacked adhesive layers, or include two stacked adhesive layers, an elastic layer and an adhesive layer, where the adhesive layer may be a double-sided adhesive, a pressure-sensitive adhesive, an ultraviolet light curing adhesive, or the like. Preferably, the elastic layer is a silicone rubber layer.

Specifically, in some embodiments, the flexible connector 20 includes an un-bent region 21 and a bent region 22, and the heightening structure 30 is located inside the bent region 22. In one embodiment, the elevating structure 30 is located at one side of the intersection of the non-bending region 21 and the bending region 22 of the flexible connecting member 20. Specifically, the bending region 22 is separated from the first bending region 221 and the second bending region 222 by a boundary between the non-bending region 21 and the bending region 22, and two sides of the first bending region 221 are connected to the non-bending region 21 and the second bending region 222, as shown in fig. 2, the padding height structure 30 may be located inside the second bending region 222, or as shown in fig. 3, the padding height structure 30 may be located inside a bend of the first bending region 221. Specifically, the flexible connector 20 is connected to the bonding area of the display panel 10 at the non-bending area 21.

In other embodiments, as shown in fig. 1, the heightening structure 30 may be integrally disposed inside the first bending region 221 and between the non-bending region 21 and the second bending region 222. In still other embodiments, the heightening structure 30 also comprises two portions respectively located inside the first bending region 221 and between the non-bending region 21 and the second bending region 222.

The display module 100 further includes at least one first antenna unit 40, and the at least one first antenna unit 40 is disposed on the elevated structure 30. The first antenna unit 40 may be one or two or more of an NFC antenna unit, a bluetooth antenna unit, a GPS antenna unit/BDS antenna unit, a radio frequency antenna unit, or an FM antenna unit.

It should be understood that the first antenna element 40 should include an antenna radiator, which is a portion of the first antenna element 40 used to receive or transmit signals. The antenna radiator may be made of one or more conductive materials such as Indium Tin Oxide (ITO), zinc oxide (ZnO), carbon Nanotube (CNT), silver nanowire (AgNW), graphene, silver, and copper. In particular, the antenna radiator comprises at least one coil. The first antenna unit 40 may further include an antenna trace electrically connected to the antenna radiator, and one end of the antenna trace may be directly connected to the flexible connector 20 of the display module 100 or connected to the flexible connector 20 through a pad of the display panel 10, so as to control the first antenna unit 40 to implement its function.

Therefore, the display module 100 of the present application, because the first antenna unit 40 is disposed on the heightening structure 30, the first antenna unit 40 is protected by the heightening structure 30 while not affecting other layer structure functions, and the first antenna unit 40 has a larger layout space, so that the number of antennas is increased, thereby meeting the requirement of the 5G technology. In addition, the first antenna unit 40 is disposed on the backlight side of the display panel 10, and a transparent material is not required, so that the cost can be saved.

In some embodiments, the first antenna element 40 is disposed within the elevated structure 30. In this way, the first antenna element 40 may be better protected by the elevated structure 30.

As shown in fig. 4, the elevating structure 30 further includes a plurality of sub-elevating layers 31 disposed in a stacked manner, and each first antenna unit 40 is disposed between two adjacent sub-elevating layers 31. The first antenna unit 40 can be placed in more positions in the heightening structure 30, and since the heightening structure 30 includes the plurality of sub-heightening layers 31, the first antenna unit 40 can be disposed on the first antenna unit 40 after the first sub-heightening layer 31 is manufactured, so that the method of operatively disposing the first antenna unit 40 in the heightening structure 30 can be simplified, and damage to the first antenna unit 40 can be reduced. In another embodiment, at least one first antenna element 40 may also be disposed within the sub-pillow layer 31.

Note that the sub-bed-up layer 31 is one of an adhesive layer and an elastic layer.

Preferably, the sub-elevating layers 31 are alternately stacked with the first antenna elements 40. In this way, the first antenna elements 40 are disposed at more positions, the number of the first antenna elements 40 is further increased, and the first antenna elements 40 are not affected by each other due to the isolation of the sub-heightening layer 31.

In other embodiments, the first antenna element 40 and the sub-heightening layer 31 may not be alternately stacked, and there is no limitation, but the uppermost layer and the lowermost layer of the heightening structure 30 should be the sub-heightening layer 31. As shown in fig. 5, in particular, at least two first antenna elements 40 are disposed between two adjacent sub-pad high layers 31. In this way, the plurality of first antenna elements 40 can be compactly disposed in the step-up structure 30.

In other embodiments, as shown in fig. 6-8, the first antenna element 40 is disposed between the heightening structure 30 and the flexible connecting member 20. Similarly, the first antenna unit 40 may be disposed between the elevated structure 30 and the display panel 10. Thus, the internal structure of the heightening structure 30 is not affected, and the heightening structure 30 can sufficiently exert its function.

Further, in some embodiments, each first antenna unit 40 is adjacent to between the heightening structure 30 and the flexible connecting member 20 or between the heightening structure 30 and the display panel 10.

In other embodiments, at least two first antenna units 40 are stacked and disposed between the elevated structure 30 and the flexible connector or between the elevated structure 30 and the display panel 10. In this manner, a plurality of first antenna elements 40 can be compactly arranged in a limited space to make the number of antennas larger.

In some embodiments, the first antenna element 40 is a plated metal pattern provided on a back side of the substrate 11. Specifically, a plated metal pattern layer is provided on the substrate 11.

In one embodiment, the substrate 11 may be a rigid substrate made of a rigid material such as glass, so that a plurality of fine process cracks are inevitably formed on the surface of the substrate 11 provided with the first antenna unit 40 in the cutting process, and the existence of the process cracks reduces the structural strength of the substrate 11 to some extent, so that the substrate 11 is easily damaged.

Therefore, in the present application, the first antenna element 40 is formed on the substrate 11 by using a metal conductive material through a plating, spraying, or the like process. In the process of electroplating or spraying, tiny metal particles enter process cracks of the substrate 11, and due to factors such as the shape and thickness of the first antenna unit 40 and the depth of the process cracks, the first antenna unit 40 formed by the metal particles fills at least part of the process cracks, so that the structural strength of the substrate 11 is effectively improved, the substrate 11 is not easy to damage, and the service lives of the display module 100 and the display terminal provided with the display panel 10 are prolonged. It is understood that the process of forming the first antenna element 40 is not limited to the above process, and other ways of filling the metal conductive material into the process gap may also be adopted.

As shown in fig. 9, in still other embodiments, the elevated structure 30 has a first surface and a second surface opposite to each other, and a side surface located between the first surface and the second surface, and the first antenna unit 40 is disposed on the side surface, wherein the first surface is closer to the display panel 10 than the second surface. Specifically, the first surface is disposed toward the display panel 10, and the second surface is disposed toward the flexible connector 20. Thus, the side surface of the heightening structure 30 is effectively utilized, the setting space of the antenna is increased, and the display effect of the display module 100 is not affected. In one embodiment, at least one first antenna element is circumferentially disposed around the side surface of the raised structure 30, or a plurality of first antenna elements are circumferentially spaced apart from each other on the side surface of the raised structure 30. In this way, the lateral space of the heightening structure 30 can be sufficiently utilized. Specifically, the first antenna element 40 is adhered to a side surface of the elevated structure 30.

Further, in some embodiments described above, the first antenna elements 40 located on the same layer or surface may be disposed at an angle with respect to each other, i.e., the central axes of any two first antenna elements 40 located on the same layer or surface of the elevated structure 30 intersect each other. Further, the first antenna unit 40 may include an antenna radiator, which is a portion of the first antenna unit 40 for receiving or transmitting a signal. The plurality of first antenna elements 40 are disposed at an angle to each other, and the plurality of antenna radiators are disposed at an angle. It will be readily appreciated that each antenna radiator in the existing design is responsible for communication at an azimuth angle, limited by the installation space and installation location of the first antenna element 40, and that there will be a "blank" azimuth angle. In the above embodiment, each first antenna element 40 may have a directional signal transceiving angle, so that the antenna radiators of the plurality of first antenna elements 40 are matched with each other to fill the aforementioned "blank" directional angle, thereby realizing the communication capability of transmitting and transceiving signals in various directions.

It should be understood that the position of the first antenna unit 40 of the display module 100 may be any combination of the first antenna unit disposed in the heightening structure 30, the second antenna unit disposed between the heightening structure 30 and the flexible connecting member, the second antenna unit disposed between the heightening structure 30 and the display panel 10, or the side surface of the heightening structure 30, which is not limited herein.

In this way, different antenna units at different positions and different angles of the heightening structure 30 can receive or transmit signals from or to various directions, thereby increasing the signal transceiving capacity of the display terminal.

Referring to fig. 5 and fig. 6 again, in some embodiments, the heightening structure 30 is provided with an accommodating groove 32 for accommodating the first antenna unit 40. As such, the first antenna element 40 may be disposed without increasing the thickness of the elevated structure 30.

Specifically, in an embodiment, the accommodating groove 32 is disposed on a side surface of the sub-elevating layer 31 facing to another adjacent sub-elevating layer 31. In this way, after one sub-elevating layer 31 is manufactured, the first antenna unit 40 is arranged in the corresponding accommodating groove 32, and then the next adjacent sub-elevating layer 31 is manufactured, so that the method for arranging the first antenna unit 40 in the elevating structure 30 in an operation mode is simplified, and the damage to the first antenna unit 40 is reduced. In another embodiment, the receiving groove 32 is disposed circumferentially adjacent to an edge of the heightening structure 30. In this way, the area of the raised structure 30 directly opposite to the display panel 10 is not greatly reduced, so that the influence of the raised structure 30 on the auxiliary action of the display panel 10 is small.

Referring to fig. 4 again, in other embodiments, the first antenna unit 40 has a layer structure. Thus, the installation space of the first antenna unit 40 can be enlarged, so that more types of first antenna units 40 can be made for 5G signal characteristics and the whole machine requirement, namely, the pattern complexity of the first antenna unit 40 is improved. In addition, the first antenna unit 40 may be disposed in the receiving groove 32, and may be any combination of a layer structure or a plated metal pattern, which is not limited herein.

In order to provide more space for disposing the antenna in the display module 100, in some embodiments, the display panel 10 further has a side surface located between the light emitting surface and the backlight surface, and the display module 100 further includes at least one second antenna unit disposed on the side surface of the display panel 10. Thus, the number of antennas in the display module 100 can be increased, and the requirement of the 5G technology can be further met. In one embodiment, at least one second antenna unit is circumferentially disposed around the side surface of the display panel 10, or a plurality of second antenna units are circumferentially spaced apart from each other on the side surface of the display panel 10. It should be understood that the second antenna element is similar in structure to the first antenna element 40 and will not be described in detail herein.

Further, the second antenna unit includes a plurality of second antenna units, and the plurality of second antenna units located on the side surface are disposed at an angle to each other, that is, central axes of any two second antenna units located on the same side surface of the display panel 100 intersect. Further, the second antenna unit may include an antenna radiator, which is a portion of the second antenna unit for receiving or transmitting signals. The plurality of second antenna units are arranged at an angle with each other, and the plurality of antenna radiators are arranged at an angle. It is easy to understand that each antenna radiator in the existing design is responsible for communication at a certain azimuth, and is limited by the installation space and installation position of the second antenna unit, and there may be a "blank" azimuth. In the above embodiment, each second antenna unit may have a directional signal transceiving angle, so that the antenna radiators of the plurality of second antenna units are matched with each other, and the aforementioned "blank" directional angle may be filled, thereby implementing the communication capability of transmitting and transceiving signals in various directions.

Therefore, different antenna units at different positions and different angles of the display module 100 can receive signals from various directions or transmit signals to various directions, thereby increasing the signal transceiving capacity of the display terminal.

In an embodiment, the substrate 11 and the package cover plate may be made of glass, so that a plurality of fine process cracks are inevitably formed on the surfaces of the substrate 11 and the package cover plate on which the second antenna unit is disposed in the cutting process, and the existence of the process cracks reduces the structural strength of the substrate 11 and the package cover plate to a certain extent, so that the substrate 11 and the package cover plate are easily damaged.

Therefore, in the present application, the second antenna element is formed by plating, spraying, etc. on the substrate 11 and/or the package cover plate with a metal conductive material. In the electroplating or spraying process, the tiny metal particles enter the process cracks of the substrate 11 and/or the packaging cover plate, and due to factors such as the shape and the thickness of the second antenna unit, the second antenna unit formed by the metal particles fills at least part of the process cracks, so that the structural strength of the substrate 11 and/or the packaging cover plate is effectively improved, the substrate 11 and the packaging cover plate are not easy to damage, and the service lives of the display module 100 provided with the display panel 10 and the display terminal are prolonged. It is to be understood that the process of forming the second antenna element is not limited to the above process, and other ways of filling the metal conductive material into the process gap may be adopted.

Further, at least one of the side of the package cover and the side of the substrate 11 is provided with a second antenna element.

Based on the same inventive concept, the application also provides a display terminal which comprises the display module.

The display terminal can be any product or part with a touch display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a vehicle-mounted device, a wearable device or an internet of things device.

Above-mentioned display module assembly and display terminal, because first antenna element 40 sets up in bed hedgehopping structure 30, first antenna element 40 has also obtained the protection of bed hedgehopping structure 30 when not influencing other layer structure functions, and first antenna element 40 has had great arrangement space, and the antenna quantity can increase to reach the requirement of 5G technique. In addition, the first antenna unit 40 is disposed on the backlight side of the display panel 10, and a transparent material is not required, so that the cost can be saved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
