[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] See also Figure 1 In a first aspect, the present application provides a display panel 10 , which includes a glass substrate 110 , an array layer 120 , and a light-emitting layer 130 stacked in sequence. The display panel 10 also includes an antenna 140 , which is at least arranged on a side wall of the glass substrate 110 .

[0049] Specifically, the glass substrate 110 is used as a substrate for preparing the array layer 120. The array layer 120 includes a driving circuit (not shown) for driving the light-emitting layer 130 to emit light. The array layer 120 includes a combination of multiple film layers in an organic layer, an inorganic layer or a metal layer. The material of the light-emitting layer 130 includes an organic light-emitting material. The antenna 140 is at least arranged on the side wall of the glass substrate 110. Since the glass substrate 110 is a rigid substrate, this will make the antenna 140 more stable and reliable. The antenna 140 can be arranged on one or more side walls of the glass substrate 110, and this application does not make specific restrictions.

[0050] In one implementation, the antenna 140 may be disposed only on the sidewall of the glass substrate 110 .

[0051] In another embodiment, the antenna 140 may not only be disposed on the sidewall of the glass substrate 110 , but may also extend to the sidewall of the array layer 120 .

[0052] In another embodiment, the antenna 140 may not only be disposed on the sidewalls of the glass substrate 110 and the array layer 120 , but may also be further extended to the sidewalls of the light emitting layer 130 .

[0053] In another embodiment, the antenna 140 may not only be disposed on the sidewall of the glass substrate 110 , but may also be further extended to the back side of the glass substrate 110 , where the back side refers to the surface of the glass substrate 110 away from the light emitting layer 130 .

[0054] In the prior art, one solution is to design the touch layer on the display surface, and set the antenna in the touch layer at the same layer. In this way, the antenna not only blocks the light and affects the display effect, but also occupies the space of the touch layer and affects the touch performance. Different from the prior art, the present application sets the antenna 140 at least on the side wall of the glass substrate 110. On the one hand, the side wall does not participate in the display, so such a design will not have any impact on the display effect. On the other hand, the antenna of the present application does not need to be combined with the touch layer, so it will not occupy the space of the touch layer, leaving room for improving the touch performance.

[0055] In one embodiment, see Figure 2 The antenna 140 includes a radiator 141 and a feeder 142, one end of the feeder 142 is electrically connected to the radiator 141; the radiator 141 is located on the side wall of the glass substrate 110, and the feeder 142 is located on the back side of the glass substrate 110, the back side is the surface of the glass substrate 110 away from the light-emitting layer 130, and the light-emitting surface is the surface of the light-emitting layer 130 away from the glass substrate 110.

[0056] Specifically, the radiator 141 is used to send and receive signals, the feeder 142 is used to transmit signals, and one end of the feeder 142 is electrically connected to the radiator 141 for transmitting the signal received and sent by the radiator 141. The radiator 141 is located on the side wall of the glass substrate 110, and the feeder 142 is located on the back of the glass substrate 110, so the radiator 141 and the feeder 142 will not affect the display effect of the display panel 10.

[0057] Of course, in some other embodiments, the radiator is located on the side wall of the glass substrate, a portion of the feeder is located on the side wall of the glass substrate, another portion is located on the back of the glass substrate, and one end of the feeder is electrically connected to the radiator.

[0058] Preferably, the radiators 141 are disposed at intervals on the sidewalls of the glass substrate 110 , which is beneficial to improving the gain of the radiators 141 .

[0059] Preferably, the radiator 141 further extends to the side wall of the array layer 120 , thereby expanding the installation space of the radiator 141 .

[0060] Preferably, the shape of the radiator 141 includes at least one of a rhombus, a rectangle, a square or a circle, and the radiator 141 can be prepared by sputtering, laser etching, printing or nanoimprinting. The material of the radiator 141 includes at least one of a nanosilver material and a graphene material. The nanosilver material and the graphene material have high conductivity and good conductivity, and are good choices for the material of the radiator 141. The feed line 142 can also be made of the same material as the radiator 141.

[0061] In one embodiment, see Figure 3 and Figure 4 A bonding portion 150 is provided on the back side of the glass substrate 110 , and the bonding portion 150 is electrically connected to the other end of the feed line 142 .

[0062] Specifically, the bonding part 150 is provided to facilitate the connection of the antenna 140 to an external circuit, and the antenna 140 can be electrically connected to the external circuit through the bonding part 150 connected to the other end of the feed line 142. The bonding part 150 is provided on the back of the glass substrate 110 without affecting the display effect.

[0063] In one embodiment, continue to refer to Figure 3 and Figure 4 The flexible circuit board 151 is located on the back of the glass substrate 110, and the flexible circuit board 151 is bonded to the bonding part 150. By further arranging the flexible circuit board 151 to be electrically connected to the bonding part 150, the antenna 140 can be electrically connected to the external circuit through the flexible circuit board 151, making the electrical connection more convenient.

[0064] In one embodiment, see Figure 3 and Figure 5 The flexible circuit board 151 and the bonding portion 150 are bonded and connected via a conductive tape 152 .

[0065] Specifically, the conductive tape 152 is different from the ACF (anisotropic conductive film) in the prior art in that it does not need to be bonded in a high-temperature environment. Since the bonding portion 150 is arranged on the back of the glass substrate 110, if ACF is used during bonding, the light-emitting layer 130 will be exposed to high temperature, which will damage the light-emitting layer 130 and ultimately affect the display effect. The conductive tape 152 used in this embodiment can avoid achieving the bonding connection effect in a high-temperature environment.

[0066] In one embodiment, continue to refer to Figure 5 The conductive tape 152 includes a conductive film 1521 and conductive adhesive 1522 located on both sides of the conductive film 1521, wherein the conductive adhesive 1522 on one side of the conductive film 1521 is used to bond the bonding portion 150 to the conductive film 1521, and the conductive adhesive 1522 on the other side of the conductive film 1521 is used to bond the flexible circuit board 151 to the conductive film 1521. The conductive film 1521 is conductive and supportive, and the conductive adhesive 1522 is conductive and adhesive. Preferably, the thickness of the conductive film 1521 is between 10 μm and 300 μm, and the thickness of the conductive adhesive is between 10 μm and 70 μm.

[0067] In one embodiment, see Figure 3 and Figure 4 The flexible circuit board 151 is also integrated with a radio frequency chip 153 .

[0068] Specifically, the RF chip 153 is electrically connected to the flexible circuit board 151 , and the signal can be directly processed through the RF chip 153 , thereby enhancing the functionality of the display panel 10 .

[0069] In one embodiment, see Figure 6 At least the area where the flexible circuit board 151 and the bonding portion 150 are bonded and connected is covered with a first waterproof film 161 .

[0070] Specifically, the first waterproof film 161 can play a waterproof role. By covering the area where the flexible circuit board 151 is bonded to the bonding part 150, the circuit in the area can be prevented from being corroded. The first waterproof film 161 can be prepared by attaching or coating. The first waterproof film 161 can only cover the area where the flexible circuit board 151 is bonded to the bonding part 150, or it can cover the entire back side of the glass substrate 110.

[0071] In one embodiment, the material of the first waterproof film 161 includes a transparent material, which helps to observe the circuits on the back side of the glass substrate 110, such as the feed line 142, the bonding part 150 and the flexible circuit board 151.

[0072] Of course, in some other implementations, structures such as a bonding portion and a flexible circuit board may not be provided on the back side of the glass substrate 110 .

[0073] In one embodiment, see Figure 7 The display panel 10 includes a display area AA and a non-display area NA surrounding the display area AA. The display panel 10 also includes a first encapsulation layer 171 and a first light shielding portion 181. The first encapsulation layer 171 is located on a side of the light-emitting layer 130 away from the glass substrate 110; the first light shielding portion 181 is located on a side of the first encapsulation layer 171 away from the glass substrate 110 and is located in the non-display area NA.

[0074] Specifically, the display panel 10 includes a display area AA and a non-display area NA. Although the light-emitting unit is located in the display area AA, the light of the light-emitting unit at an oblique angle will still leak out from the non-display area NA, resulting in light leakage. In this embodiment, the first light shielding portion 181 is arranged on the surface of the first encapsulation layer 171 away from the glass substrate 110, and is located in the non-display area NA, which can avoid the light leakage in the non-display area NA. At the same time, in the prior art, black ink is usually arranged on the frame area of ​​the cover plate, but there are fluctuations in the process accuracy of the bonding between the cover plate and the display panel. Therefore, in order to achieve a better light-shielding effect of the ink, the size of the cover plate is usually enlarged, and the width of the frame is finally increased. In this embodiment, the first light shielding portion 181 is directly arranged on the first encapsulation layer 171, and there is no fluctuation in the accuracy of the bonding process. The size of the cover plate can be designed to be smaller, and the overall size can be reduced to achieve the effect of reducing the frame.

[0075] In one embodiment, the first light shielding portion 181 surrounds the display area AA, so as to ensure that the light shielding effect of each edge of the display area AA is consistent.

[0076] In one implementation, the material of the first light shielding portion 181 may be a black material, wherein the black material includes a black organic material, wherein the black organic material may also be an organic material with pigment or carbon powder added thereto.

[0077] In one embodiment, the material of the first light shielding portion 181 can also be black glue. Transparent optical glue is set on the display area AA, and black glue is set on the non-display area NA. The thickness of the two is consistent so that the surface away from the glass substrate 110 is flat.

[0078] Preferably, the transmittance of the first light shielding portion 181 is less than or equal to 0.01%.

[0079] In one embodiment, see Figure 7 The display panel 10 also includes a second encapsulation layer 172, the second encapsulation layer 172 includes a first encapsulation sub-portion 1721 and a second encapsulation sub-portion 1722, the first encapsulation sub-portion 1721 is located on the side of the first light shielding portion 181 away from the glass substrate 110, and the orthographic projection of the first encapsulation sub-portion 1721 on the glass substrate 110 completely overlaps with the orthographic projection of the first encapsulation layer 171 on the glass substrate 110; the second encapsulation sub-portion 1722 is located on the surface of the radiator 141 away from the glass substrate 110.

[0080] Specifically, the first encapsulation sub-portion 1721 of the second encapsulation layer 172 covers the surface of the first light shielding portion 181 and the first encapsulation layer 171 for secondary encapsulation to improve the encapsulation effect, and the second encapsulation sub-portion 1722 of the second encapsulation layer 172 covers the surface of the radiator 141 on the side to prevent the radiator 141 from being corroded. The first encapsulation sub-portion 1721 and the second encapsulation sub-portion 1722 can be connected together as a whole, or they can be separated from each other and independently encapsulate their respective areas, which is not limited in this application. The first encapsulation layer 171 and the second encapsulation layer 172 include at least one inorganic layer, and may further include an organic layer, wherein the inorganic layer improves the performance of blocking water vapor, and the organic layer increases the planarization effect, wherein the material of the inorganic layer includes at least one of silicon oxide, silicon nitride or silicon oxynitride.

[0081] Preferably, the first encapsulation sub-portion 1721 covers the surface of the first light shielding portion 181 away from the glass substrate 110 and covers the side wall of the first light shielding portion 181 close to the display area AA. The first encapsulation sub-portion 1721 can provide better protection for multiple surfaces of the first light shielding portion 181.

[0082] Preferably, the second encapsulation sub-portion 1722 covers the radiator 141, the first encapsulation layer 171, the first light shielding portion 181 and the side wall of the first encapsulation sub-portion 1721 away from the display area AA, and the first encapsulation sub-portion 1721 and the second encapsulation sub-portion 1722 are connected to form a sealing structure. The second encapsulation sub-portion 1722 covers the radiator 141, the first encapsulation layer 171, the first light shielding portion 181 and the side wall of the first encapsulation sub-portion 1721 in all directions, and is connected to the first encapsulation sub-portion 1721, thereby enhancing the protection effect of the display panel 10.

[0083] In one embodiment, the first encapsulation layer or the second encapsulation layer may be prepared by chemical vapor deposition or atomic layer deposition.

[0084] In one embodiment, continue to refer to Figure 7 The display panel 10 further includes a second waterproof film 162 , and the second waterproof film 162 is at least located on a surface of the second packaging sub-portion 1722 away from the glass substrate 110 .

[0085] Specifically, the second waterproof membrane 162 and the second packaging sub-section 1722 both have good water-blocking effects. Covering the second waterproof membrane 162 on the surface of the second packaging sub-section 1722 can provide a better water-blocking effect for the side antenna 140. That is, when one of them fails, the other can still provide a water-blocking effect, thereby preventing the antenna 140 structure from being corroded, thereby extending the service life of the antenna 140.

[0086] In one embodiment, see Figure 7The second waterproof film 162 further extends to the back of the glass substrate 110 in the non-display area NA. In this way, the second waterproof film 162 can better cover the corner of the antenna 140 from the side to the back, and can better protect the antenna 140.

[0087] In one embodiment, see Figure 7 The second waterproof film 162 further extends to the surface of the first encapsulation sub-portion 1721 in the non-display area NA away from the glass substrate 110. In this way, the second waterproof film 162 can better cover the second encapsulation layer 172 from the side to the corner of the light emitting surface, and can achieve a better water blocking effect.

[0088] Of course, in some other implementations, only the second waterproof membrane may be provided to cover the antenna, or only the second packaging sub-unit may be provided to cover the antenna.

[0089] A second aspect of the present application provides a display module 20, see Figure 8 The display module 20 includes the display panel 10 in any of the above embodiments, and further includes a polarizer 210, an optical glue 220, and a cover plate 230. The polarizer 210 is located on the side of the light-emitting layer 130 away from the glass substrate 110; the optical glue 220 is located on the side of the polarizer 210 away from the glass substrate 110; and the cover plate 230 is located on the side of the optical glue 220 away from the glass substrate 110.

[0090] Specifically, the polarizer 210 is arranged on the light-emitting surface of the display panel 10 to reduce the reflection efficiency of external light, thereby improving the display effect of the light-emitting layer 130. The cover plate 230 is used to protect the display panel 10. The optical glue 220 is a transparent glue material that allows the polarizer 210 and the cover plate 230 to be bonded together.

[0091] In one embodiment, continue to refer to Figure 8 The display module 20 also includes a second shading portion 240 , which is located at least on the side wall of at least one of the film layers between the polarizer 210 and the optical adhesive 220 ; wherein the edge of the cover plate 230 protrudes from the edge of the optical adhesive 220 .

[0092] Specifically, the second light shielding portion 240 is disposed on the side wall of a portion of the film layer of the display module 20, and may be the side wall of one of the polarizer 210 and the optical glue 220, or may be the side wall of both the polarizer 210 and the optical glue 220. The second light shielding portion 240 can block the light leaking from the side wall to avoid the phenomenon of side light leakage. In addition, the width of the second light shielding portion 240 may be equal to the width of the cover plate 230 protruding from the optical glue 220, or may be smaller than the width of the cover plate 230 protruding from the optical glue 220.

[0093] Preferably, the material of the second light shielding portion 240 includes black glue, for example, it can be acrylic, silicone, fluorine, polyurethane and other materials.

[0094] In one embodiment, see Fig. 9 The second light shielding portion 240 is located on the side walls of all film layers between the glass substrate 110 and the optical adhesive 220. The second light shielding portion 240 is completely filled on the side walls of other film layers except the cover plate 230, which helps to improve the effect of preventing light leakage from the side walls.

[0095] In one embodiment, see Fig.10 A groove is provided at the edge of the optical adhesive 220, and the second light shielding portion 240 is filled into the groove.

[0096] Specifically, since the display panel 10 has a non-display border area, in order to enhance the shading effect in the non-display border area, a groove is provided in the edge of the optical glue 220, and the second shading portion 240 is filled into the groove. The second shading portion 240 in the groove can block the light in the non-display area of ​​the light emitting surface of the display panel 10, thereby reducing the light leakage effect.

[0097] In some other embodiments, a groove is provided at the edge of the polarizer, and the second light shielding portion is filled into the groove of the polarizer.

[0098] In one embodiment, see Fig.10 The second light shielding portion 240 includes a first light shielding sub-portion 241 and a second light shielding sub-portion 242. The first light shielding sub-portion 241 is in the same layer as the optical adhesive 220 and at least partially fills the groove. The second light shielding sub-portion 242 is located on the side walls of the polarizer 210 and the display panel 10. The first light shielding sub-portion 241 is arranged in the groove of the optical adhesive 220 and mainly functions to block light leakage in the non-display area of ​​the light output surface. The second light shielding sub-portion 242 is arranged on the side walls of the polarizer 210 and the display panel 10 and mainly functions to block light leakage on the side. Of course, the part of the first light shielding sub-portion 241 that is not arranged in the groove of the optical adhesive 220 can also block light leakage on the side.

[0099] Furthermore, in some embodiments, considering that a coating process is used when preparing the second light-shielding portion 240, and the final shape of the second light-shielding portion 240 is not composed of multiple ideal rectangles, the second light-shielding portion 240 will form a structure with a certain taper (tilt) angle, which will reduce the light-shielding effect. Based on this, in order to achieve a better light-shielding effect, the following implementation is provided.

[0100] In one embodiment, see Fig.11 and Fig.12The first light shielding sub-portion 241 includes a first inclined surface facing away from the optical adhesive 220 , and an angle θ1 between the first inclined surface and the stacking direction of the film layers in the display module 20 is greater than a first preset angle.

[0101] Specifically, the stacking direction refers to the stacking direction of the polarizer 210, the optical glue 220 and the cover plate 230. Due to the coating process, the final first light shielding sub-unit 241 forms a taper angle, i.e., a first inclined plane, on the surface away from the optical glue 220, thereby reducing the light shielding effect of the first light shielding sub-unit 241. In this embodiment, the angle θ1 between the first inclined plane and the stacking direction of the film layer in the display module 20 is further set to be greater than the first preset angle, thereby ensuring the light shielding effect of the first light shielding sub-unit 241. The first preset angle is greater than or equal to 50 degrees, and preferably, the first preset angle is greater than or equal to 54 degrees. For example, the first preset angle can be 50 degrees, 54 degrees, or 80 degrees.

[0102] In one embodiment, see Fig.11 and Fig.12 The second light shielding sub-portion 242 includes a second inclined surface facing away from the polarizer 210 and the display panel 10 , and an angle θ2 between the second inclined surface and the stacking direction of the film layer in the display module 20 is smaller than a second preset angle.

[0103] Specifically, the stacking direction refers to the stacking direction of the polarizer 210, the optical adhesive 220 and the cover plate 230. Due to the coating process, the final second light shielding sub-unit 242 forms a taper angle, i.e., a second inclined plane, on the surface away from the polarizer 210 and the display panel 10, thereby reducing the light shielding effect of the second light shielding sub-unit 242. In this embodiment, the angle θ2 between the second inclined plane and the stacking direction of the film layer in the display module 20 is further set to be less than the second preset angle, thereby ensuring the light shielding effect of the second light shielding sub-unit 242. The second preset angle is less than or equal to 40 degrees, and preferably, the first preset angle is greater than or equal to 36 degrees. For example, the first preset angle can be 40 degrees, 36 degrees, or 15 degrees.
