Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully 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.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

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.

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

As described in the background, "5G" is a fifth generation mobile communication technology. The millimeter wave is an electromagnetic wave with the wavelength of 1-10 mm, the wavelength range of the millimeter wave is in the overlapping area of the microwave and the far infrared wave, and the millimeter wave has the characteristics of two wave spectrums of the microwave and the far infrared wave. For users, due to the large bandwidth caused by the high working frequency of the millimeter waves, high-speed data transmission can be achieved, the 5G peak data transmission rate can reach 10-20 Gbps, and the millimeter waves 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 device to arrange more antennas so as to meet the requirement of the 5G technology. However, in experiments, it is found that 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 reduced, and therefore, 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 parts and the communication quality of the antenna need to be considered, and the layout difficulty of the 5G antenna is further increased.

In order to solve the above problem, the display device of the present application includes the display module 100 for implementing image display, the antenna unit 36 is integrated with the display module 100, and the antenna unit 36 may constitute one or two or more of an NFC antenna, a bluetooth antenna, a GPS antenna/BDS antenna, a radio frequency antenna, or an FM antenna, so that the space of the omitted display module 100 is fully utilized, and the arrangement space of the antenna is effectively increased.

Hereinafter, the display module 100 according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings. For the purpose of illustration, the drawings show only the structures associated with embodiments of the invention.

Fig. 1 is a schematic diagram illustrating a stacked structure of a display module 100 according to an embodiment of the invention; fig. 2 is a schematic diagram illustrating a stacked structure of the display module 100 according to another embodiment of the invention. The display module 100 according to the embodiment of the invention includes a display substrate 32, an encapsulation structure 34, a polarization layer 40 and a cover plate 60. It is understood that the structure of the display module 100 is not limited thereto, and may further include other functional film layers, which are not limited herein, for example, a touch layer group may also be included.

The display substrate 32 may include a substrate, a driving layer group, a light emitting element, and an encapsulation structure, which are stacked. The light emitting element includes at least an anode, a light emitting layer, and a cathode, and the driving layer group includes a thin film transistor and a wire to control emission of each light emitting element, or the amount of emission when each light emitting element emits can be controlled. The packaging structure is arranged on the substrate and used for preventing the light-emitting element from being influenced by the external environment and reducing the deterioration 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.

It is understood that the tft is well known to those skilled in the art, and the detailed structure and principle thereof will not be described herein.

As shown in fig. 1, in some embodiments, the display substrate 32 is a rigid display substrate, and the substrate of the display substrate 32 may be a rigid substrate formed of a rigid material such as glass.

The package structure 34 (Encap) includes a package cover plate made of rigid materials such as glass, and a frame sealing adhesive is filled between the display substrate 32 and the package structure 34 to bond the display substrate 32 and the package structure 34 together, so as to form a sealed space between the display substrate 32 and the package structure 34. Thus, the package structure 34 can encapsulate and protect the display substrate 32, and prevent the display failure caused by the contact of water and oxygen in the air with the light emitting elements of the display substrate 32.

Fig. 3 illustrates a side view of the display module 100 shown in fig. 1.

As shown in the drawings, when the display substrate 32 and the package structure 34 are disposed in an opposite manner, the package structure 34 covers directly above the display substrate 32, the light emitting device layer of the display substrate 32 faces the package structure 34, a backlight surface 321 is formed on a side of the display substrate 32 away from the package structure 34, and a light emitting surface 341 is formed on a side surface of the package structure 34 away from the display substrate 32. The side surface of the display substrate 32 and the side surface of the package structure 34 together form a side surface of the display module 100. Thus, the display module 100 has a light-emitting surface 341 and a backlight surface 321 disposed oppositely, and a side surface located between the light-emitting surface 341 and the backlight surface 321.

The display module 100 may be 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 device. In the present application, the top electrode of the light emitting device may be a transparent electrode, the bottom electrode may be a reflective electrode, and the light emitted from the light emitting layer directly emits from the top electrode or emits from the top electrode after being reflected by the bottom electrode, so that the light emitting surface 341 is formed on the surface of the side of the package structure 34 away from the display substrate 32, and the backlight surface 321 is formed on the side of the display substrate 32 away from the package structure 34.

As shown in fig. 2, in some other embodiments, the display substrate 32 may also be a flexible display substrate, the substrate of the display substrate 32 is a flexible substrate formed by Polyimide (PI), and the encapsulation structure 34 includes a thin film encapsulation layer formed by laminating an organic layer and an inorganic layer. With reference to fig. 1 and fig. 3, the display module 100 further includes at least one antenna unit 36, and the at least one antenna unit 36 is disposed on a side surface of the display module 100. Thus, the area of the side surface of the display module 100 is effectively utilized, the installation space of the antenna unit 36 is increased, and the image display of the light emitting surface 341 is not affected. Compared with the prior art, the antenna unit 36 can be arranged in the display terminal, and the requirement of the 5G technology is met while the size of the display terminal is not increased.

Further, at least one of the side of the package structure 34 and the side of the substrate of the display substrate 32 is provided with an antenna unit 36.

As shown in fig. 3, when the display substrate 32 is a rigid display substrate, in particular, in some embodiments, the substrate side of the display substrate 32 is provided with a plurality of antenna units 36 at intervals along the circumferential direction, and the side of the package structure 34 is provided with a plurality of antenna units 36 at intervals along the circumferential direction. In other embodiments, only one antenna element 36 circumferentially surrounding the display substrate 32 is disposed on a side of the substrate of the display substrate 32, and only one antenna element 36 circumferentially surrounding the package structure 34 is disposed on a side of the package structure 34. Thus, the side space of the display substrate 32 and the package structure 34 is fully utilized. It is understood that the shape and number of the antenna elements 36 are not limited, and may be set according to different requirements.

It is understood that in other embodiments, at least one antenna unit 36 may be disposed only on the side of the substrate of the display substrate 32, or at least one antenna unit 36 may be disposed only on the side of the package structure 34, which may also increase the disposition space of the antenna unit 36.

When the display substrate 32 is a flexible display substrate, as shown in fig. 4, in some embodiments, the side of the package structure 34 is provided with a plurality of antenna units 36 at intervals along the circumferential direction. In other embodiments, only one antenna element 36 circumferentially surrounding the package structure 34 is provided on a side of the package structure 34. In this way, the side space of the package structure 34 is fully utilized. It is understood that the shape and number of the antenna elements 36 are not limited, and may be set according to different requirements.

Fig. 5 shows a schematic diagram of the light-emitting surface 341 of the display module 100 according to an embodiment of the invention, and fig. 6 shows a schematic diagram of the light-emitting surface 341 of the display module 100 according to another embodiment of the invention.

As shown in the drawings, in some embodiments, the light exit surface 341 is provided with the antenna unit 36 on the basis that the antenna unit 36 is provided on the side surface of the display module 100. Thus, the installation space of the antenna unit 36 is further enlarged, so that more antenna units 36 can be installed on the display module 100.

In some embodiments, the display module 100 has a display Area (AA Area) and a non-display Area surrounding the display Area, the antenna unit 36 located on the light-emitting surface 341 is at least partially located in the non-display Area, and the antenna unit 36 located in the non-display Area utilizes the space of the light-emitting surface 341 in the non-display Area while not affecting the display effect of the display module 100.

As shown in fig. 4 and 5, the antenna unit 36 on the light emitting surface 341 is completely located in the non-display region. Specifically, in some embodiments, the light exit surface 341 has only one antenna unit 36, and the antenna unit 36 is circumferentially disposed around the display region and continuously extends around the display region to form a strip structure. As shown in fig. 4 and fig. 6, in other embodiments, the light exit surface 341 is provided with a plurality of antenna units 36, the antenna units 36 are disposed at intervals around the display area, and the distance between adjacent antenna units 36 and the shape of each antenna unit 36 are not limited and may be set according to actual requirements. It is understood that the specific shape of the antenna unit 36 is not limited thereto, and may be set as desired.

It is understood that, in some embodiments, the antenna units 36 may also be formed of a transparent material, so that at least a portion of the antenna units 36 may be disposed in the display area of the light-emitting surface 341, thereby making full use of the light-emitting surface 341 to arrange more antenna units 36 and avoiding affecting the display effect of the display area.

The display region is an active region in which light-emitting elements are formed in the longitudinal direction, and includes at least a driving layer group, a planarizing layer, an anode, a light-emitting unit, and a cathode, which are provided in this order. The non-display area refers to a peripheral area surrounding the display area, which is not allowed to be cut off, such as wiring for providing signal lines for the display area, and the arrangement of a driving circuit and a chip.

Fig. 7 is a schematic diagram of the backlight surface 321 of the display module 100 according to an embodiment of the invention. In some embodiments, the backlight surface 321 is provided with at least one antenna unit 36 on the basis of the antenna unit 36 on the side surface of the display module 100.

Since the backlight surface 321 faces away from the light emitting surface 341 and no light or a small amount of light passes through, the antenna unit 36 can be laid on the whole area of the backlight surface 321 without affecting the image display of the display module 100, so that the area of the backlight surface 321 can be fully utilized, and the arrangement space of the antenna unit 36 is significantly increased. It is understood that the shape of the antenna unit 36 disposed on the backlight surface 321 is not limited, and may be different according to the requirement. In addition, the antenna unit 36 can also reflect light, thereby improving the light extraction efficiency of the display module 100.

It should be noted that, in some embodiments, the antenna units 36 located on the same surface may be disposed at an angle to each other, that is, the central axes of any two antenna units 36 located on the same side surface of the display module 100 intersect. Further, the antenna unit 36 may include an antenna radiator, which is a portion of the antenna unit 36 for receiving or transmitting signals. The antenna elements 36 are disposed at an angle to each other, and the antenna radiators are disposed at an angle. It will be readily appreciated that each antenna radiator in the prior art design is responsible for azimuth communications, and is limited by the installation space and location of the antenna elements 36, and that there will be a "blank" azimuth. In the above embodiment, each antenna unit 36 may have a directional signal transceiving angle, so that the antenna radiators of the antenna units 36 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.

Further, the inventors found in their research that, when the display substrate 32 is a rigid display substrate and the substrate of the display substrate 32 and the package structure 34 are both made of glass, a plurality of fine process cracks are inevitably formed on the surface of the substrate of the display substrate 32 and the surface of the package structure 34 in the cutting process, and the existence of the process cracks reduces the structural strength of the substrate of the display substrate 32 and the package structure 34 to a certain extent, so that the substrate of the display substrate 32 and the package structure 34 are easily damaged. When the display substrate 32 is a flexible display substrate, a slight force will cause the display substrate 32 to deform, resulting in failure and damage to the circuits, pixels and the package structure 34 distributed on the substrate surface. Therefore, in the present application, the antenna unit 36 is formed by electroplating, spraying, etc. on the substrate of the display substrate 32 and/or the package structure 34 by using a metal conductive material. When the substrate of the display substrate 32 and the package structure 34 are both made of glass, in the electroplating or spraying process, the tiny metal particles enter the substrate of the display substrate 32 and/or the process cracks of the package structure 34, and due to factors such as the shape and the thickness of the antenna unit 36 and the depth of the process cracks, the antenna unit 36 formed by the metal particles fills at least part of the process cracks, so that the structural strength of the substrate of the display substrate 32 and/or the package structure 34 is effectively improved, the substrate of the display substrate 32 and the package structure 34 are not easily damaged, and the service life of the display module 100 and the display terminal is prolonged. When the display substrate 32 is a flexible display substrate, the antenna unit 36 can play a supporting role, so that the structural strength of the display substrate 32 is effectively improved, and the failure and damage of the circuits, pixels and the packaging structures 34 distributed on the surface of the substrate are avoided.

Specifically, the metal conductive material includes one or more of metal conductive materials such as Indium Tin Oxide (ITO), zinc oxide (ZnO), silver nanowires (AgNW), silver, and copper. It is to be understood that the metal conductive material is not limited to this kind, and other materials may be used as needed.

It will be appreciated that the process of forming the antenna element 36 is not limited to the above, and other ways of filling the metallic conductive material into the process gap may be used.

In some embodiments, the polarizing layer 40 is formed of PVC film, anti-glare layer (AG film), low reflection/non-reflection layer (LR/AR) or WVDLC optical compensation film, and the polarizing layer 40 is used to filter the ambient light irradiated to the display module 100 and prevent the ambient light from being reflected after being irradiated to the display module 100, and the reflected light is mixed with the light emitted from the display module 100 to affect the pattern actually displayed by the display module 100. Since the structure of the polarizing layer 40 is well known to those skilled in the art, it will not be described herein.

In some embodiments, the cover plate 60 may be made of glass, sapphire, polyvinyl chloride (PVC), etc. for protecting the display module 100 and other film layers.

In some embodiments, the display module 100 further includes an adhesive layer 50. Specifically, the material of the Adhesive layer 50 may be one of Optical Clear Adhesive (OCA), Pressure Sensitive Adhesive (PSA), Optical Clear Resin (OCR), or any combination thereof, and is used for adhering the polarizing layer 40 and the cover plate 60.

In one embodiment, at least one antenna element 36 is also disposed in the adhesive layer 50, so that the space of the adhesive layer 50 further increases the space for disposing the antenna element 36. The antenna element 36 is protected by the adhesive layer 50 while not affecting the function of the adhesive layer 50 itself.

Further in some embodiments, the adhesive glue layer 50 includes multiple sub-adhesive glue layers arranged in a stack, and at least one antenna element 36 may be arranged in any two adjacent sub-adhesive glue layers. Thus, as the number of sub-adhesive layers increases, the number of antenna elements 36 may further increase, and the antenna elements 36 may be separated from each other to avoid interference.

In some embodiments, the display module 100 further includes a heat dissipation layer 10 and a buffer layer 20. Specifically, the heat dissipation layer 10 is formed of a conductive material having a good heat dissipation effect and ductility, so as to dissipate heat generated by the display module 100 during a display process. The buffer layer 20 may be formed of or include a polymer resin such as polyurethane, polycarbonate, polypropylene, and polyethylene, or a material having elasticity such as rubber and sponge, having an effect of absorbing external impact.

Further, in some embodiments, the heat dissipation layer 10 is formed by at least one antenna unit 36 on a side of the buffer layer 20 away from the display module 100. Thus, when the installation space of the antenna unit 36 is further increased, the antenna unit 36 is adopted to dissipate heat to replace the heat dissipation layer 10, so that the thickness of the display module 100 is effectively reduced.

Based on the same inventive concept, the embodiment of the present invention further provides a display terminal, which includes the display module 100 in the above embodiment.

The display terminal can be any product or part with a touch display function, such as a mobile phone, a tablet personal 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 100 and display terminal, the space that has utilized display module assembly 100 sets up antenna element 36, consequently when not influencing display module assembly 100's display effect, has increased antenna element 36's the space of placing, and then makes the antenna element 36 quantity in the display terminal increase, finally promotes display terminal's whole transmitting power, satisfies the requirement of 5G technique. Moreover, as part of the antenna units 36 are filled in the process cracks on the display module 100, the structural strength of the display module 100 is effectively improved, and the probability of damage caused by external impact is reduced.

Unless mentioned to the contrary, singular terms may include the plural and are not to be construed as being one in number.

It will also be understood that when interpreting elements, although not explicitly described, the elements are to be interpreted as including a range of errors which are within the acceptable range of deviation of the particular values as determined by those skilled in the art. For example, "about," "approximately," or "substantially" may mean within one or more standard deviations, without limitation.
