Fig. 1 is a schematic structural diagram of a display module according to an embodiment of the present invention, fig. 2 is a cross-sectional view of the display module shown in fig. 1, and referring to fig. 1 and fig. 2, the display module 100 includes: a display substrate 10 on which a plurality of light emitting units 11 are disposed; the cover plate 20 is located on the light emitting side of the display substrate 10, and an antenna structure 21 is disposed on one side of the cover plate 20 facing the display substrate 10, where the antenna structure 21 is a mesh structure.
The display substrate 10 is a panel structure capable of displaying images, and a circuit structure (not shown) for driving the light emitting unit 11 to emit light is integrated thereon. The light emitting units 11 may be light emitting chips, and are electrically connected to the circuit structure on the display substrate 10 by soldering or the like, and the circuit structure drives light emission, and as a whole, the plurality of light emitting units 11 may form a plurality of pixels, thereby displaying a picture. The cover plate 20 is a protection structure for protecting the circuit structure on the display substrate 10 and the light emitting unit 11, and in some embodiments, the cover plate 20 and the display substrate 10 may be optionally used to form a sealed cavity to prevent the circuit structure on the display substrate 10 and the light emitting unit 11 from being oxidized and corroded by air and water vapor.
In the embodiment of the present invention, the antenna structure 21 is disposed on the side of the cover plate 20 facing the display substrate 10, which substantially means that the antenna structure 21 is prepared on the surface of one side of the cover plate 20 before the cover plate 20 is attached to the display substrate 10, and after the preparation is completed, the surface is aligned and attached to the display substrate 10. On one hand, the design can fully utilize the space between the cover plate 20 and the display substrate 10 to accommodate the newly added antenna structure 21, and then the communication function is realized by receiving and sending signals through the antenna; on the other hand, the manufacturing difficulty and the cost for preparing the antenna structure 21 on the surface of the cover plate are both low, the antenna structure can be prevented from being prepared on the display substrate 10, the film layer design and the manufacturing difficulty of the display substrate 10 are simplified and reduced, and the reduction of the production cost is facilitated.
The antenna structure 21 may specifically form a metal pattern by deposition processes such as magnetron sputtering, thermal evaporation or chemical vapor deposition, so as to form an antenna, the antenna structure 21 may be made of a metal material such as silver, aluminum, or an alloy material, and the transmittance of the antenna structure 21 is adjusted by controlling the line width, the size of the hollow hole, the film thickness, and the like in the mesh structure, so as to avoid the influence on the light emission of the light emitting unit 11 on the display substrate 10.
It should be noted that the antenna structure 21 and the light emitting unit 11 in fig. 1 and fig. 2 are only used as examples, and the size ratio and the position relationship thereof are not limited, and it is understood that, since the antenna structure 21 is a grid structure formed by intersecting lines, the lines and the light emitting unit 11 may be in a mutually offset relationship in a direction perpendicular to the display substrate or may be in a projection overlapping relationship. For the antenna structure 21 of the mesh structure, even if there is a projection overlap between the lines and the light emitting unit 11, the light emitting from the light emitting unit 11 is less affected.
Specifically, the light emitting unit 11 may be a micro light emitting diode, a mini light emitting diode, a nano light emitting diode, and the like, the light emitting diodes are mainly different in size, and are all packaged light emitting diode chips, and the light emitting diodes may be attached to corresponding positions of the display substrate 10 by a bulk transfer technique. Of course, the light emitting unit 11 is not limited to a light emitting chip, and may be a light emitting device formed on the display substrate 10 by preparation, and the driving light emission is also realized by a circuit structure, and finally, the picture display is realized.
According to the technical scheme, the display substrate and the cover plate are arranged in the display module, the display substrate is provided with the plurality of light-emitting units, the cover plate is arranged on the light-emitting side of the display substrate, the antenna structure is arranged on one side, facing the display substrate, of the cover plate, the antenna structure is in a grid structure in the layout mode, the cover plate can be used as a bearing body of the antenna structure, the film preparation and the light-emitting units of the display substrate cannot be influenced, the space structure in the display panel can be effectively utilized, the film design on the display substrate is simplified, the manufacturing difficulty of the display substrate is reduced, and the space utilization rate in the panel is also improved; meanwhile, the antenna structure is set to be a mesh grid structure, so that light emitting of the light emitting unit on the display substrate is not interfered, and normal and good display effect can be ensured.
With continued reference to fig. 2, in an alternative embodiment, a perpendicular projection of the antenna structure 21 onto the plane of the display substrate 10 at least partially overlaps with the area of the display substrate 10 where the light emitting unit 11 is located.
The overlapping area exists between the vertical projection of the antenna structure 21 and the area where the light-emitting unit 11 is located, which means that the antenna structure 21 does not need to be specially arranged in an area outside the light-emitting unit 11, that is, the arrangement position of the light-emitting unit 11 is avoided without considering the shielding of the light emitted by the light-emitting unit 11. Therefore, the antenna structure 21 can be disposed in the area where the light emitting unit 11 is located, so that a larger space can be provided for freely disposing the antenna structure 21, and excessive restrictions on the shape, size, layout and the like of the antenna structure 21 are avoided, thereby also contributing to reducing the design and manufacturing difficulties of the antenna structure 21.
With continued reference to the display module shown in fig. 1, in an alternative embodiment of the present invention, the display module may be configured to include a coupling region 110, the coupling region 110 is located at an edge region of the display module, the coupling region 110 is configured with a coplanar waveguide structure 30, and the antenna structure 21 extends to the coupling region 110 and is coupled to the coplanar waveguide structure 30. The display module further comprises a flexible circuit board 40 and a feed source (not shown in the figure), wherein one end of the flexible circuit board 40 is connected with the feed source, and the other end of the flexible circuit board 40 is bound on the coupling area 110 and is electrically connected with the coplanar waveguide structure 30; the feed is used for transceiving antenna signals to the antenna structure 21 through the flexible wiring board 40 and the coplanar waveguide structure 30.
The coupling region 110 is a region of the display module that couples to the antenna structure 21 for transmitting or receiving signals, and the coplanar waveguide structure 30 disposed in the region is not in direct electrical contact with the antenna structure 21, but the coplanar waveguide structure 30 and the antenna structure 21 form a coupling, and transmit signals in a waveguide manner. The feed source is a primary radiation source for providing electromagnetic radiation to the antenna, and functions to convert high-frequency current or waveguide energy into electromagnetic radiation energy, and the flexible circuit board 40 is responsible for transmitting the high-frequency current or waveguide energy to the coplanar waveguide structure 30, and the coplanar waveguide structure 30 transmits electromagnetic signals to the antenna in a waveguide form. It should be noted that the feed source can be generally integrated on the main board of the driving display module, and the main board transmits and receives signals to the antenna through the feed source.
In this embodiment, the optional coplanar waveguide structure is integrated into a flexible wiring board 40 (not shown), and the flexible wiring board 40 is bonded to the side of the cover plate 20 facing the display substrate 10. In this embodiment, after the cover plate 20 is formed with the antenna structure 21 and before the cover plate is attached to the display substrate 10, the flexible circuit board 40 is bonded to the coupling region 110 of the cover plate 20 to ensure that signals can be transmitted and received to and from the antenna structure 21.
In addition, in view of the fact that a step area is generally arranged on a display substrate in the conventional display module to bind a flexible circuit board, the embodiment of the invention also provides an implementation mode in order to avoid the complexity of the whole display module due to the excessive flexible circuit board. Fig. 3 is a cross-sectional view of another display module according to an embodiment of the present invention, referring to fig. 3, in another embodiment of the present invention, a coplanar waveguide structure 30 is optionally disposed on a side of the display substrate 10 where the light emitting unit 11 is disposed, and a vertical projection of the antenna structure 21 on a plane of the display substrate 10 at least partially overlaps the coplanar waveguide structure 30.
At this time, the coplanar waveguide structure 30 is disposed on a side of the display substrate 10 facing the cover plate 20, and by binding the flexible circuit board 40, the coupling between the coplanar waveguide structure 30 and the antenna structure 21 can still be ensured, so as to couple the high-frequency signal into the antenna structure 21 on the cover plate. Meanwhile, a binding region can be arranged in the edge region of the display substrate 10, the binding terminal for integrated display driving and the binding terminal for receiving and transmitting antenna signals are integrated, the area of the display substrate is fully utilized, a binding step can be prevented from being arranged on the cover plate glass, the binding process on the cover plate glass can be omitted, and for the cover plate, only the antenna structure 21 needs to be prepared, so that the convenience of the whole process is improved, and the overall cost is reduced.
With continued reference to fig. 1, the antenna structure 21 may be configured to include a plurality of antenna elements 211 and a plurality of feeding lines 212, wherein one end of each of the feeding lines 212 is correspondingly coupled to one of the antenna elements 211, and the other end of each of the feeding lines 212 is coupled to the coupling region 110.
Further, the coplanar waveguide structure 30 includes a plurality of waveguide units 31, and the plurality of waveguide units 31 are sequentially arranged along the edge of the display substrate 10; the waveguide unit 31 comprises a central conductor strip 311 and two conductor plane structures 312, the two conductor plane structures 312 being located on both sides of the central conductor strip 311.
In this embodiment, the plurality of antenna units 211 transmit and receive signals independently, and the feed line 212 and the waveguide unit 31 corresponding to each antenna unit 211 are responsible for transmitting high-frequency current between the feed source and the antenna unit. There is a partial overlap of the center conductor strip 311 and the feed line 212 in a direction perpendicular to the surface of the display substrate so that the antenna element 211 is coupled to the coplanar waveguide structure 30 through the feed line 212.
In addition, for the design of the multiple antenna units 211, in order to implement independent operation between the antenna units 211, the embodiment of the present invention provides a more specific implementation manner. Specifically, a phase shifter (not shown in the figure) may be included in the feed source, and the feed source may transmit and receive signals to and from the antenna unit 211 in turn through the phase shifter and the feed line. As described above, the feed source may be provided in the main board of the display device, and a phase shifter may be integrated in the feed source, and the phase shifter functions to shift the phase of the signal by an angle, so that different electromagnetic wave signals can be transmitted and received to and from the respective antenna elements 211. In other words, the antenna elements in this embodiment are fed separately, and beam scanning is achieved by means of an external phase shifter.
Based on the same coupling principle, the embodiment of the invention also provides an antenna setting mode. Fig. 4 is a schematic structural diagram of another display module according to an embodiment of the present invention, and referring to fig. 4, an optional antenna structure 21 includes a power distribution network 210 and a plurality of antenna units 211, where the plurality of antenna units 211 are respectively electrically connected to the power distribution network 210, and the power distribution network 210 is coupled to the coupling area 110.
Further, the coplanar waveguide structure 30 includes a center conductor strip 311 and two conductor plane structures 312, the two conductor plane structures 312 being located on both sides of the center conductor strip 311.
The power distribution network 210 performs synchronous feeding excitation on the plurality of antenna elements 211, and distributes output power to each antenna element 211. The feeder in the power dividing network 210 and the central conductor strip 311 in the coplanar waveguide structure 30 are partially overlapped in a direction perpendicular to the surface of the display substrate, so that the power dividing network 210 and the coplanar waveguide structure 30 are coupled, and the feeder can synchronously transmit and receive signals to and from the plurality of antenna units 211 through the coplanar waveguide structure 30 and the power dividing network 210.
In addition, considering the optimization of the performance of the antenna for transmitting and receiving signals when the antenna is integrated on the cover plate, the display substrate can be optionally further designed in the embodiment of the invention so as to enhance the signal transmitting and receiving capacity of the antenna towards the light-emitting side. Fig. 5 and 6 are cross-sectional views of two display modules according to an embodiment of the present invention, and referring to fig. 5 and 6, specifically, the optional display substrate 10 includes a substrate 121 and a thin film transistor array layer 122, the thin film transistor array layer 122 includes a plurality of thin film transistors 1220, and the thin film transistors 1220 are electrically connected to the light emitting units 11. The thin film transistor array layer 122 includes at least one mesh metal layer 1221, and the mesh metal layer 1221 receives a ground signal, and the mesh metal layer 1221 is multiplexed as an antenna signal reflection layer.

The tft array layer 122 generally includes a plurality of metal pattern layers to form a plurality of tfts and connecting traces, wherein in some display substrate designs, a metal pattern layer in the form of a mesh grid, i.e., a mesh grid metal layer 1221, is formed, and the mesh grid metal layer 1221 receives a ground signal when the light emitting unit 11 is driven to operate.

Based on the structure, the antenna structure is arranged on one side, facing the display substrate, of the cover plate, the grid metal layer in the display substrate can be used as the antenna signal reflection layer, and antenna signals emitted by the antenna structure are reflected and emitted from the light emitting side, so that the antenna signals can be prevented from being dispersed, and the strength of the antenna signals is improved.
