Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1 is a first schematic structural diagram of a functional module according to an exemplary embodiment. As shown in fig. 1, the function module includes:

a display component 101;

an antenna assembly including an antenna radiator; wherein the antenna radiator comprises at least one conductor grid 102;

a grid of conductors 102 located on the lower surface of the display element 101 or embedded within the display element 101.

In the embodiment of the disclosure, the function module is applied to a terminal device, and the terminal device may be a mobile terminal and a wearable electronic device. The mobile terminal comprises a mobile phone, a notebook computer and a tablet computer; this wearable electronic equipment includes the smart watch, and this disclosed embodiment does not put a limit to.

The display component is used for displaying information. The Display assembly includes a Display assembly formed of a Cathode Ray Tube (CRT), a Liquid Crystal Display (LCD), or an Organic Light-Emitting Diode (OLED), and embodiments of the present disclosure are not limited thereto.

The antenna assembly can realize communication among devices and is widely applied to smart phones, tablet computers or smart watches. In some embodiments, an antenna assembly comprises: an ultra-wideband antenna assembly, a wireless fidelity antenna assembly, or a millimeter wave antenna assembly.

The ultra-wideband antenna assembly is used for receiving and transmitting wireless signals in a frequency band of 3.1GHz to 10.6 GHz; the wireless fidelity antenna assembly is used for receiving and transmitting wireless signals in a frequency band from 5.925GHz to 7.125 GHz; the millimeter wave antenna assembly is used for receiving and transmitting wireless signals in a frequency band of 26.5GHz to 300 GHz. Therefore, the antenna assembly has high central frequency for receiving and transmitting wireless signals, and small antenna clearance required during signal receiving and transmitting, so that the antenna assembly can be integrated with the display assembly.

In other embodiments, the antenna assembly may further include: a satellite antenna assembly for receiving satellite signals. The satellite antenna assembly is used for transceiving radio signals at a frequency of 1575.42MHz or 1228 MHz.

The antenna assembly comprises an antenna radiator comprising a conductor grid. The conductor grid is made of a metal or alloy material.

The conductor grid can be used as an antenna radiator for receiving and transmitting wireless signals. Wherein, when transmitting the wireless signal, the conductor grid converts the high-frequency current into high-frequency electromagnetic wave; when receiving wireless signals, the conductor mesh converts received high-frequency electromagnetic waves into high-frequency currents.

In the embodiment of the present disclosure, the conductor grid is a mesh structure formed by crossing strip conductors. In the case that the area of the conductor grid is the same as the number of strip conductors contained in the conductor grid, the width of the strip conductors in the conductor grid is inversely related to the light transmittance of the conductor grid. For example, the light transmittance of the conductor grid with a large width of the strip conductor is smaller than that of the conductor grid with a small width of the strip conductor.

That is to say, the embodiment of the present disclosure can ensure the transmittance of the conductor grid by setting the width of the strip conductor, thereby satisfying different display requirements of the display module. For example, the requirement of high display brightness in the display component can be met by shortening the width of the strip conductor; the requirement of low display brightness requirement in the display assembly can be met by increasing the width of the strip conductors.

In the embodiment of the present disclosure, the width of the strip conductors included in the conductor grid is smaller than the set width threshold. The set width threshold may be experimentally derived or set based on historical empirical values. For example, the set width threshold may be set according to a historical width value corresponding to the historical transmittance meeting different display brightness scenes in the display assembly. For another example, the set width threshold may be determined by obtaining a transmittance meeting the display brightness requirement through an experiment and determining a width value corresponding to the transmittance obtained through the experiment.

The width of the strip conductor can be smaller than the gap value between two pixels in the display assembly and can also be smaller than the width of one sub-pixel in the display assembly.

Illustratively, the set width threshold may be in a range between 0.3 mm and 0.2 mm.

It should be noted that the conductor grid includes at least two meshes. The number of meshes in the conductor grid is inversely related to the light transmittance of the conductor grid on the basis of the same area of the conductor grid. For example, the light transmittance of a conductor mesh with a large number of meshes is smaller than that of a conductor mesh with a small number of meshes. In the disclosed embodiment, the area of each mesh in the conductor grid may be equal. Therefore, the conductor grids can be uniformly transparent, and the display effect of the display assembly can be improved.

It should be noted that the shape of the mesh includes a rectangle, a diamond, or other irregular shape, and the disclosed embodiments are not limited thereto. As shown in fig. 2, the mesh shape in the conductor grid is diamond shaped. As shown in fig. 3, the mesh shape in the conductor grid is rectangular.

In some embodiments, the conductor grid has a closed grid border, as shown in fig. 4. Therefore, when the conductor grids transmit and receive wireless signals, high-frequency current in the conductor grids can be distributed along the grid frame, so that the current distribution in the conductor grids is uniform, the effective length of the transmitting and receiving wireless signals corresponding to the uniform current distribution is increased, and the efficiency of the conductor grids for transmitting and receiving the wireless signals can be improved.

In embodiments of the present disclosure, the conductor grid is located on a lower surface of the display assembly or embedded within the display assembly. That is, the conductor grid may be applied within a display assembly.

In some embodiments, the antenna assembly comprises: an ultra-wideband antenna assembly;

the ultra-wideband antenna assembly includes at least three conductor grids.

That is, the embodiments of the present disclosure may provide at least three conductor meshes in the display assembly, and collectively transmit and receive wireless signals of the UWB band through the at least three conductor meshes. The at least three conductor grids may be provided on the lower surface of different layers within the display assembly. For example, the at least three conductive grids may be disposed on a lower surface of a transparent plate in the display module, may be disposed on an optical colloid in the display module, and may be disposed on a polyimide PI film layer in the display module, which is not limited in the embodiments of the present disclosure.

Illustratively, fig. 5 is a simulation diagram of the transmitting and receiving efficiency of a UWB antenna assembly applied in a display assembly. In fig. 5, the abscissa is frequency, and the unit of frequency is GHz. The ordinate is the transmit-receive efficiency in dB. Fig. 6 is a schematic diagram illustrating measured transmission and reception efficiency of a UWB antenna assembly applied in a display assembly. In fig. 6, the abscissa is frequency, and the unit of frequency is MHz. The ordinate is the transmit-receive efficiency in dB.

As shown in fig. 5 and 6, the maximum value of the transmitting and receiving efficiency of the UWB antenna assembly applied in the display assembly can be more than-10 dB. Therefore, the receiving and transmitting efficiency of the UWB antenna assembly applied in the display assembly can meet the receiving and transmitting efficiency of the antenna assembly from both the simulation schematic diagram and the actual measurement schematic diagram.

It will be appreciated that the conductor grid of the antenna assembly in embodiments of the present disclosure is located on the lower surface of the display assembly or embedded within the display assembly. That is to say, the conductor grid and the display component are not two independent devices distributed at different positions in the terminal equipment, but are structurally fused to form a functional module with a display function and a communication function, so that the integration level of the functional module can be improved; meanwhile, the conductor grids of the antenna assemblies are applied to the display assemblies, application scenes of the antenna assemblies can be expanded, and the antenna assemblies are more flexible to set.

In some embodiments, the display assembly comprises: a transparent plate;

and the conductor grid is positioned on the lower surface of the transparent plate.

In the embodiment of the present disclosure, the transparent plate may be a glass plate made of glass material or a transparent plastic plate made of plastic material in the display module, and the embodiment of the present disclosure is not limited thereto.

It can be understood that the conductor grids of the embodiments of the present disclosure can be flexibly disposed on the lower surface of the transparent plate of the display component, thereby improving the flexibility of the arrangement of the conductor grids.

If the pixel array is a pixel array comprising liquid crystal molecules, the corresponding first substrate can be an array substrate; the second substrate may be a Color Filter (CF) substrate.

The conductor grid is arranged on the surface of the first substrate and comprises: the conductor grid is positioned on the surface of the first substrate facing the pixel array.

The above-mentioned conductor grid may also be embedded in the first substrate. The conductor grid is embedded in the first substrate and comprises: a groove is arranged on the first substrate; the conductor grid is disposed within the groove.

It should be noted that the grooves are used for accommodating the conductor grids. The area of the groove is inversely related to the frequency at which the conductor mesh transmits and receives radio signals. For example, the area of the groove is smaller when the frequency of the conductor mesh for transmitting and receiving radio signals is high than when the frequency of the transmitted and received radio signals is low.

In the embodiment of the present disclosure, the cover plate is a transparent cover plate and is located at the outermost side of the display module, and the display content of the display module can be seen through the cover plate. The cover plate can be used for protecting a first substrate, a second substrate and a pixel array between the first substrate and the second substrate, wherein the first substrate and the second substrate are positioned below the cover plate in the display assembly.

It will be appreciated that the grid of conductors may be located not only on the lower surface of the first substrate that faces the light emitting face of the pixel array, but also on the lower surface of the protective cover plate. Thus, the flexibility of the conductor mesh arrangement can be improved.

In some embodiments, the grid of conductors is located on a gel bonded to an inner surface of the first substrate facing the array of pixels;

the colloid comprises: and black glue for dividing adjacent pixels in the pixel array.

That is, the grid of conductors may be located not only on the substrate with the light emitting surface of the pixel array facing, but also on the gel in the pixel array. Thus, the flexibility of the conductor mesh arrangement can be improved.

The gel includes black gel that segments adjacent pixels in the pixel array. The black glue includes, but is not limited to, black hot melt glue.

In some embodiments, the display assembly further comprises: an optical colloid layer located between the first substrate and the second substrate;

the conductor grid is located on the optical colloid layer.

That is, the grid of conductors may be located not only on the first substrate surface, but also on the optical glue layer. Thus, the flexibility of the conductor mesh arrangement can be improved.

In some embodiments, the display assembly further comprises: the polyimide PI film layer is positioned between the first substrate and the second substrate;

the conductor grid is located on the PI film layer.

In the embodiment of the disclosure, the PI thin film layer is used for interlayer insulation. In this public embodiment, the conductor net not only can be located first base plate surface and optical cement layer, still can be located the PI thin layer, can improve the flexibility that the conductor net set up.

In some embodiments, the conductor grid is disposed within the display assembly by an evaporation process, an injection molding process, or a printing process.

That is, the conductor mesh may be formed on the lower surface of the first substrate in the transparent plate through an evaporation process, an injection molding process, or a printing process; the conductor grid may also be formed on the lower surface of the cover plate by an evaporation process, an injection molding process or a printing process.

In the embodiment of the present disclosure, the printing process includes a printing direct forming process or a laser direct forming process, and the embodiment of the present disclosure is not limited.

It can be appreciated that the conductor grids can be formed on the transparent plate according to different processes, and the flexibility of conductor grid arrangement is improved.

In some embodiments, the display assembly further comprises: the liquid crystal display module and the backlight module provide a display light source for the liquid crystal display module; the backlight module comprises an optical film material;

the conductor grid is attached to the surface of the optical film material.

In the embodiment of the present disclosure, the optical film includes, but is not limited to, a diffusion sheet, a prism sheet, or a reflection sheet. The diffusion sheet is used for diffusing the light rays into uniform light rays; the prism sheet is used for refracting or totally reflecting light rays and brightening the display effect of the liquid crystal display module; the reflector plate is used for reflecting light rays into the light guide plate in the backlight module.

It should be noted that, because the conductor grid is designed to be a mesh, and the strip conductors formed in the conductor grid are very thin, the optical effect of attaching the conductor grid to the surface of the optical film on the optical film is very small, and the requirement of the optical film for transmitting light can be met.

It will be appreciated that the grid of conductors may be located not only on the transparent plate, but also on the optical film.

In some embodiments, as shown in fig. 8, the conductor grid 102 is located at the edge of the display assembly 101.

It will be appreciated that locating the conductor grid at the edge of the display assembly facilitates connection of the conductor grid to other devices (e.g., feed lines, etc.) in the antenna assembly, enabling optimization of the device layout.

The feeder is used for transmitting the first high-frequency current or the second high-frequency current. The radio frequency front end module is used for providing a first high-frequency current to the feeder line.

It will be appreciated that locating the feed points at the edges of the conductor grid enables the routing length of the feed lines to be reduced. Of course, in other embodiments, the feeding point may also be disposed at an intermediate position of the conductor grid, and the specific disposition position may be determined according to the radiation requirement of the antenna.

Therefore, the conductor grids and the fingerprint identification area are arranged at different positions, so that the influence of the conductor grids on fingerprint identification can be reduced, and the fingerprint identification is more accurate.
