Referring to fig. 1 to 8, a first aspect of an embodiment of the present application provides a display panel.
As shown in fig. 1, the display panel 100 includes a substrate 110, a driving array layer 120 and an antenna 130, the driving array layer 120 is located on a side of the substrate 110 close to a light emitting surface of the display panel 100, and the antenna 130 is located on a side of the driving array layer 120 far from the light emitting surface. And at least part of the substrate 110 is located at a side of the antenna 130 away from the light exit surface.
It should be noted that the antenna 130 may be one or more of a Near Field Communication (NFC) antenna, a bluetooth antenna, a Global Positioning System (GPS) antenna, a BeiDou Navigation Satellite System (BDS) antenna, a Frequency Modulation (FM) antenna, or a radio Frequency antenna.
In this embodiment, the display panel 100 is a flexible display panel, and the display panel 100 may further include a light emitting layer, a polarizing layer, a touch layer, and a flexible cover plate, where the light emitting layer, the polarizing layer, the touch layer, and the cover plate are sequentially stacked and disposed on one side of the driving array layer 120 away from the substrate 110, and a Thin Film Transistor (TFT) is disposed in the driving array layer 120 to control the light emitting layer to emit light. The side of the light emitting layer away from the driving array layer 120 is a light emitting surface of the display panel 100.
It should be noted that, by disposing the antenna 130 on the side of the driving array layer 120 close to the substrate 110, at least a portion of the substrate 110 is located on the side of the antenna 130 away from the light emitting surface. Compared with the antenna 130 integrated on the touch layer, on one hand, the antenna 130 can be independently prepared on the substrate 110 without integrating the preparation process of the antenna 130 and the preparation process of the touch layer, so that the difficulty in setting the antenna 130 is reduced; on the other hand, no other module (touch layer) is arranged on the same horizontal plane, the antenna 130 can occupy most or all of the space, the arrangement space of the antenna 130 is increased, and more antennas 130 can be arranged; on the other hand, since the antenna 130 is far away from the touch layer, the mutual interference between the antenna 130 and the touch layer is avoided to the greatest extent, and the signal strength of the antenna 130 is improved.
It should be noted that, in the embodiment of the present application, the antenna 130 may be disposed at the following two positions, the first position being: the antenna 130 is located within the substrate 110; and the second method comprises the following steps: the antenna 130 is located between the substrate 110 and the driven array layer 120. The present embodiment will be described mainly by taking the first embodiment as an example.
Specifically, the substrate 110 includes a first substrate 111 and a second substrate 112 stacked together, the antenna 130 is located between the first substrate 111 and the second substrate 112, and the driving array layer 120 is located on a side of the first substrate 111 away from the second substrate 112.
It is understood that the substrate 110 may also be a plurality of layers, and the embodiment of the present application is described by taking the substrate 110 as two layers, specifically including the first substrate 111 and the second substrate 112.
The antenna 130 is disposed between the first substrate 111 and the second substrate 112, and may be disposed in the following two ways.
In the first embodiment, one of the first substrate 111 and the second substrate 112 has a groove 113 thereon, or, as shown in fig. 5, the first substrate 111 and the second substrate 112 each have a groove 113, and the antenna 130 is located in the groove 113. In this way, after the space for accommodating the antenna 130 is dug out on the first substrate 111 and the second substrate 112 and the antenna 130 is placed, the increase in the thickness of the substrate 110 can be avoided, thereby reducing the thickness of the display panel 100.
In the second embodiment, as shown in fig. 2, the antenna 130 is distributed in a whole layer between the first substrate 111 and the second substrate 112, that is, the orthographic projection of the antenna 130 on the first substrate 111 coincides with the surface of the first substrate 111 close to the second substrate 112. Thus, the antenna 130 may form a complete film structure. Compared with the first embodiment, the groove is prevented from being dug on the substrate 110, the difficulty in arranging the antenna 130 is reduced, in addition, the arrangement space of the antenna 130 can be further increased, and the signal intensity of the antenna 130 is improved.
It should be noted that, compared with the mode in which the antenna 130 and the touch module are integrated, in the embodiment of the present application, the antenna 130 is disposed on the backlight side of the driving array layer 120, so that the thickness between the driving array layer 120 and the reflective layer 180 is increased, and the transmission path of the external electromagnetic signal from the reflective layer 180 to the driving array layer 120 is increased, thereby increasing the transmission difficulty of the external electromagnetic signal to the driving array layer 120, reducing the interference of the external electromagnetic signal to the driving array layer 120, and ensuring the normal operation of the driving array layer 120.
In one possible implementation, the material of the first substrate 111 and the second substrate 112 may be the same, and the material of the first substrate 111 may include glass, Polycarbonate (PC) plastic, Polymethyl Methacrylate (PMMA), Polyethylene terephthalate (PET), Polyimide (PI), and the like. In the embodiment of the present application, the material of the first substrate 111 and the second substrate 112 is not limited, and a user may select the material according to actual circumstances. In the embodiment of the present application, the material of the first substrate 111 is polyimide.
In one possible implementation manner, as shown in fig. 2, the display panel 100 further includes a ground layer 140, the ground layer 140 is located on a side of the second substrate 112 away from the driving array layer 120, and the ground layer 140 is electrically connected to a ground circuit of the display panel 100. The orthographic projection of the ground plane 140 on the second substrate 112 covers the orthographic projection of the antenna 130 on the second substrate 112. Thus, the ground layer 140 is perpendicular to the second substrate 112, so that interference of external signals to signals of the antenna 130 can be shielded to the greatest extent, and the signal strength of the antenna 130 can be improved.
In an embodiment of the present application, the display panel 100 may include an antenna assembly, wherein the antenna assembly includes an antenna 130 and a ground layer 140. By disposing the ground layer 140, interference of external electromagnetic signals to the antenna 130 can be reduced, and the signal strength of the antenna 130 can be improved. The ground layer 140 may be formed through a patterning process using a low resistance metal, which may include, but is not limited to, one or more of silver (Ag), gold (Au), copper (Cu), aluminum (Al), platinum (Pt), palladium (Pd), chromium (Cr), titanium (Ti), tungsten (W), niobium (Nb), tantalum (Ta), vanadium (V), iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni), zinc (Zn), tin (Sn), molybdenum (Mo), and calcium (Ca). The ground layer 140 may have a grid-like structure, and may have a regular polygon (e.g., square), a rectangle, a parallelogram (e.g., diamond), other polygons, or other irregular shapes.
Specifically, a dielectric layer 150 is arranged between the antenna 130 and the ground layer 140; the thickness and dielectric constant of the dielectric layer 150 are related to the signal strength of the antenna 130. Specifically, at the same frequency, the product of the thickness and the dielectric constant of the dielectric layer 150 is a constant value, and therefore, in order to ensure higher signal strength, the dielectric constant should be made smaller when the thickness is larger, and the dielectric constant should be made larger when the thickness is smaller.
Specifically, the dielectric constant of the dielectric layer 150 is between 1.5 and 10, wherein the dielectric constant of the dielectric layer 150 may be 1.5, 5 or 10. The thickness of the dielectric layer 150 is between 50-800 μm, wherein the thickness of the dielectric layer 150 may be 50 μm, 400 μm, or 800 μm. The dielectric constant and the thickness of the dielectric layer 150 are within the above ranges, which enables the antenna 130 to have a high signal strength on one hand and the display panel 100 to have a thin thickness on the other hand. In a specific manufacturing process, the dielectric constant and the thickness of the dielectric layer 150 may be adjusted according to the signal strength required by the antenna 130.
In the embodiment of the present application, as shown in fig. 1, a supporting film 160, a protective layer 170 and a light reflecting layer 180 are stacked on a side of the second substrate 112 away from the driving array layer 120, and the supporting film 160 is located on a side of the protective layer 170 close to the second substrate 112. Specifically, the supporting film layer 160 is made of polyethylene terephthalate, the protective layer 170 is made of foam, and the reflective layer 180 is made of copper foil.
It should be noted that the supporting film layer 160 may support the flexible display panel 100, so as to improve the structural strength of the flexible display panel 100. The protection layer 170 may buffer the display panel 100 to prevent the display panel 100 from being damaged by external force. The reflective layer 180 may reflect external light, so as to prevent the external light from affecting the light emitting performance of the display panel 100. In addition, a thermal insulation layer may be disposed between the reflective layer 180 and the protective layer 170, and the thermal insulation layer may insulate external heat, so as to prevent the external heat from being transferred to the light emitting layer of the display panel 100 and affecting the light emitting performance of the display panel 100. The material of the thermal insulation layer may be polyimide.
In the embodiment of the present application, the ground layer 140 may be disposed at the following two positions.
In a first possible implementation, as shown in fig. 2, the ground layer 140 is located between the support film layer 160 and the second substrate 112, such that the second substrate 112 forms the dielectric layer 150.
In a second possible implementation, as shown in fig. 3, the ground layer 140 is located between the support film layer 160 and the protection layer 170, such that the support film layer 160 and the second substrate 112 together form the dielectric layer 150. The user can select one of the above two setting modes according to actual needs to set the position of the ground layer 140. The two different arrangement modes can be convenient for users to select, and the arrangement difficulty of the ground layer 140 can be reduced.
In one possible implementation, as shown in fig. 1, the reflective layer 180 may be reused as the ground layer 140, and the protective layer 170, the supporting film 160 and the second substrate 112 together form the dielectric layer 150. This arrangement can increase the function of the reflective layer 180, and avoid the additional arrangement of the ground layer 140, thereby reducing the thickness of the display panel 100.
In one possible implementation, as shown in fig. 1, the antenna 130 includes a conductive layer 131, an insulating layer 132, and a connection line layer 133, the connection line layer 133 is electrically connected to the conductive layer 131, and the insulating layer 132 is located between the conductive layer 131 and the connection line layer 133; wherein the conductive layer 131 is used for radiating and receiving signals; the other end of the connection line layer 133 is connected to the integrated circuit chip of the display panel 100 for transmitting a signal of the conductive layer 131 to the integrated circuit chip. The conductive layer 131 may include a plurality of conductive lines that are interlaced with each other, and the interlaced conductive lines form a grid. In addition, the insulating layer 132 may be filled in the gaps between the conductive layer 131 and the connection line layer 133, so as to ensure the planarization of the planes of the conductive layer 131 and the connection line layer 133, and improve the uniformity of the surfaces of the conductive layer 131 and the connection line layer 133.
It is understood that the material of the connection line layer 133 and the conductive layer 131 may be the same, wherein the material of the conductive layer 131 may include, but is not limited to, one or more of silver (Ag), gold (Au), copper (Cu), aluminum (Al), platinum (Pt), palladium (Pd), chromium (Cr), titanium (Ti), tungsten (W), niobium (Nb), tantalum (Ta), vanadium (V), iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni), zinc (Zn), tin (Sn), molybdenum (Mo), and calcium (Ca). The shape of the conductive layer 131 may be regular polygon (e.g., square), rectangle, parallelogram (e.g., diamond), other polygon, or other irregular shape.
The conductive layer 131, the insulating layer 132, and the connection line layer 133 may be disposed in the following two ways.
In a first possible implementation, as shown in fig. 1, 2, 3, and 6, a conductive layer 131, an insulating layer 132, and a connection line layer 133 are sequentially stacked and disposed between the first substrate 111 and the second substrate 112. The insulating layer 132 may be provided with a via 1321, and the conductive layer 131 and the connection line layer 133 are electrically connected through the via 1321. This arrangement can ensure the maximum space for disposing the conductive layer 131, and improve the signal strength of the antenna 130.
In a second possible implementation, as shown in fig. 4, the conductive layer 131, the insulating layer 132, and the connection line layer 133 are located at the same level. This arrangement can reduce the thickness of the antenna 130 to the maximum, thereby reducing the thickness of the display panel 100. The two modes can make the structure of the antenna 130 richer and reduce the difficulty in setting the antenna 130. It is understood that, in this configuration, the insulating layer 132 may also be provided with traces (not shown), the traces extending in a direction parallel to the horizontal plane of the insulating layer 132 and having one end electrically connected to the conductive layer 131 and the other end electrically connected to the connecting line layer 133.
In the embodiment of the present application, another arrangement of the conductive layer 131, the insulating layer 132, and the connection line layer 133 of the antenna 130 may also be adopted, as shown in fig. 7, a groove (not shown) is formed on the first substrate 111, the conductive layer 131 is located in the groove, the insulating layer 132 is located on a side of the first substrate 111 close to the second substrate 112, the connection line layer 133 is located on a portion of the surface of the second substrate 112, the insulating layer 132 is located on the remaining surface of the second substrate 112, a via 1321 is disposed in the insulating layer 132, and the via 1321 electrically connects the conductive layer 131 and the connection line layer 133. It is understood that the coverage area of the orthographic projection of the conductive layer 131 on the first substrate 111 and the coverage area of the orthographic projection of the connecting line layer 133 on the first substrate 111 can be adjusted according to practical applications, and the embodiment of the present application is not limited thereto.
The embodiment of the present application further provides another arrangement manner of the antenna position, as shown in fig. 8, the antenna 130 is located on one side of the substrate 110 close to the light emitting surface, and an interlayer dielectric layer 190 is disposed between the antenna 130 and the driving array layer 120. The interlayer dielectric layer 190 may perform isolation and insulation functions, on one hand, it is convenient to dispose the driving array layer 120 on the side of the antenna 130 away from the substrate 110, and on the other hand, it prevents the antenna 130 and the driving array from interfering with each other.
