Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display panel, display module, and display device. Background Technology

[0002] As technology advances, the functionality of display devices is constantly being upgraded, and antennas, as components in display devices that receive and transmit signals, are also undergoing continuous technological advancements.

[0003] One approach is to design the antenna on the display screen, which can reduce or avoid hand obstruction. One existing solution is to integrate the antenna with the touch layer. Although this can improve the overall integration, the antenna will occupy part of the touch layer, which will reduce the touch performance. At the same time, integrating the antenna on the display screen will block some light, causing optical display problems such as moiré patterns, diffraction, and graininess. Summary of the Invention

On the other hand, the antenna of this application does not need to be combined with the touch layer, so it will not occupy the space of the touch layer and leave room for improvement of touch performance.

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0048] See Figure 1 The first aspect of this application provides a display panel 10, which includes a glass substrate 110, an array layer 120 and a light-emitting layer 130 stacked sequentially. The display panel 10 also includes an antenna 140, which is at least disposed on the sidewall of the glass substrate 110.

[0049] Specifically, the glass substrate 110 serves as the substrate for fabricating 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 comprises a combination of multiple film layers, including organic, inorganic, or metallic layers. The material of the light-emitting layer 130 includes organic light-emitting materials. The antenna 140 is disposed at least on a sidewall of the glass substrate 110. Since the glass substrate 110 is a rigid substrate, this makes the antenna 140 more stable and reliable. The antenna 140 may be disposed on one or more sidewalls of the glass substrate 110; this application does not impose specific limitations.

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

[0051] In another embodiment, the antenna 140 can be disposed on the sidewall of the glass substrate 110, or it can extend to the sidewall of the array layer 120.

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

[0053] In another embodiment, the antenna 140 can be disposed on the sidewall of the glass substrate 110, and can also extend 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 existing technologies, one approach is to design the touch layer on the display surface, with the antenna disposed in the same layer within the touch layer. However, this not only blocks light, affecting the display effect, but also occupies space in the touch layer, impacting touch performance. Unlike existing technologies, this application places the antenna 140 at least on the sidewall of the glass substrate 110. Firstly, the sidewall does not participate in the display, so this design does not affect the display effect. Secondly, the antenna in this application does not need to be integrated with the touch layer, thus not occupying space in the touch layer and leaving room for improved touch performance.

[0055] In one embodiment, see Figure 2 The antenna 140 includes a radiator 141 and a feed line 142. One end of the feed line 142 is electrically connected to the radiator 141. The radiator 141 is located on the side wall of the glass substrate 110, and the feed line 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 transmit and receive signals, and the feed line 142 is used to transmit signals. One end of the feed line 142 is electrically connected to the radiator 141 to transmit the signals transmitted and received by the radiator 141. The radiator 141 is located on the side wall of the glass substrate 110, and the feed line 142 is located on the back side of the glass substrate 110. Therefore, the radiator 141 and the feed line 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 sidewall of the glass substrate, a portion of the feed line is located on the sidewall of the glass substrate, and another portion is located on the back side of the glass substrate, with one end of the feed line electrically connected to the radiator.

[0058] Preferably, the radiators 141 are spaced apart on the sidewalls of the glass substrate 110. This is beneficial for improving the gain of the radiators 141.

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

[0060] Preferably, the radiator 141 has a shape including at least one of rhombus, rectangle, square, or circle, and can be fabricated by sputtering, laser etching, printing, or nanoimprinting. The material of the radiator 141 includes at least one of nanosilver and graphene. Nanosilver and graphene have high conductivity and good electrical conductivity, making them preferred materials for 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. The antenna 140 can be electrically connected to the external circuit through the bonding part 150, which is connected to the other end of the feed line 142. The bonding part 150 is located on the back of the glass substrate 110 and will not affect the display effect.

[0063] In one embodiment, see further. Figure 3 and Figure 4 The flexible circuit board 151 is located on the back of the glass substrate 110 and is bonded to the bonding portion 150. By further configuring the flexible circuit board 151 to be electrically connected to the bonding portion 150, the antenna 140 can be electrically connected to an 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 part 150 are bonded together by conductive tape 152.

[0065] Specifically, the conductive tape 152 differs from the existing ACF (anisotropic conductive film) in that it does not require bonding in a high-temperature environment. Since the bonding portion 150 is located on the back side of the glass substrate 110, if ACF is used during bonding, the light-emitting layer 130 will be exposed to high temperatures, which will damage the light-emitting layer 130 and ultimately affect the display effect. However, the conductive tape 152 used in this embodiment can achieve the bonding connection effect without high-temperature environment.

[0066] In one embodiment, see further. Figure 5 The conductive tape 152 includes a conductive film 1521 and conductive adhesive 1522 located on both sides of the conductive film 1521. The conductive adhesive 1522 on one side of the conductive film 1521 is used for bonding 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 for bonding the flexible circuit board 151 to the conductive film 1521. The conductive film 1521 is conductive and has supporting properties, and the conductive adhesive 1522 is conductive and has adhesive properties. 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 also integrates an RF chip 153.

[0068] Specifically, the radio frequency chip 153 is electrically connected to the flexible circuit board 151, and the signal can be processed directly through the radio frequency 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 is bonded to the bonding portion 150 is covered with a first waterproof membrane 161.

[0070] Specifically, the first waterproof membrane 161 serves a waterproof function, preventing corrosion of the circuitry in the area where the flexible circuit board 151 is bonded to the bonding portion 150 by covering it. The first waterproof membrane 161 can be prepared by adhesive bonding or by coating. The first waterproof membrane 161 may cover only the area where the flexible circuit board 151 is bonded to the bonding portion 150, or it may cover the entire back side of the glass substrate 110.

[0071] In one embodiment, the first waterproof membrane 161 is made of a transparent material. This facilitates observation of the wiring on the back side of the glass substrate 110, such as the feed line 142, the bonding portion 150, and the flexible circuit board 151.

[0072] Of course, in some other embodiments, the bonding portion, flexible circuit board and other structures 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 the side of the light-emitting layer 130 away from the glass substrate 110. The first light-shielding portion 181 is located on the 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, light from 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 part 181 is disposed 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 light leakage in the non-display area NA. At the same time, in the prior art, black ink is usually applied to the frame area of ​​the cover plate. However, there are fluctuations in the process precision of the bonding between the cover plate and the display panel. Therefore, in order to achieve a better light-shielding effect, the size of the cover plate is usually increased, which ultimately increases the width of the frame. In this embodiment, the first light-shielding part 181 is directly disposed on the first encapsulation layer 171, which eliminates the precision fluctuations of the bonding process. The size of the cover plate can be designed to be smaller, thereby reducing the overall size and achieving the effect of reducing the frame.

[0075] In one embodiment, the first light-shielding portion 181 surrounds the display area AA. This ensures that the light-shielding effect is consistent across all edges of the display area AA.

[0076] In one embodiment, the material of the first light-shielding part 181 can be a black material, wherein the black material includes a black organic material, and the black organic material can also be an organic material with added pigments or toner.

[0077] In one embodiment, the material of the first light-shielding part 181 can also be black glue. A transparent optical glue is provided on the display area AA, while a black glue is provided on the non-display area NA. The thickness of both is the same, so that the surface away from the glass substrate 110 is flat.

[0078] Preferably, the transmittance of the first light-shielding part 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, which includes a first encapsulation sub-part 1721 and a second encapsulation sub-part 1722. The first encapsulation sub-part 1721 is located on the side of the first light-shielding part 181 away from the glass substrate 110, and the orthographic projection of the first encapsulation sub-part 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-part 1722 is located on the surface of the radiator 141 away from the glass substrate 110.

[0080] Specifically, the first encapsulation sub-part 1721 of the second encapsulation layer 172 covers the surfaces of the first light-shielding part 181 and the first encapsulation layer 171 for secondary encapsulation to improve the encapsulation effect. The second encapsulation sub-part 1722 of the second encapsulation layer 172 covers the surface of the side radiator 141 to prevent the radiator 141 from being corroded. The first encapsulation sub-part 1721 and the second encapsulation sub-part 1722 can be integrally connected together, or they can be separately encapsulated for their respective areas; this application does not impose any limitations. The first encapsulation layer 171 and the second encapsulation layer 172 include at least one inorganic layer, and may further include an organic layer. The inorganic layer improves the performance of blocking moisture, and the organic layer increases the planarization effect. The material of the inorganic layer includes at least one of silicon oxide, silicon nitride, or silicon oxynitride.

[0081] Preferably, the first encapsulation sub-part 1721 covers the surface of the first light-shielding part 181 opposite to the glass substrate 110 and the sidewall of the first light-shielding part 181 near the display area AA. The covering of multiple surfaces of the first light-shielding part 181 by the first encapsulation sub-part 1721 provides better protection.

[0082] Preferably, the second encapsulation sub-part 1722 covers the radiator 141, the first encapsulation layer 171, the first light-shielding part 181, and the sidewall of the first encapsulation sub-part 1721 facing away from the display area AA. The first encapsulation sub-part 1721 and the second encapsulation sub-part 1722 are connected to form a sealed structure. By comprehensively covering the radiator 141, the first encapsulation layer 171, the first light-shielding part 181, and the sidewall of the first encapsulation sub-part 1721 with the second encapsulation sub-part 1722, and forming a connection with the first encapsulation sub-part 1721, the protective effect on the display panel 10 is enhanced.

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

[0084] In one embodiment, see further. Figure 7 The display panel 10 also includes a second waterproof membrane 162, which is located at least on the surface of the second encapsulation portion 1722 away from the glass substrate 110.

[0085] Specifically, both the second waterproof membrane 162 and the second encapsulation sub-part 1722 have good water-blocking effect. Covering the surface of the second encapsulation sub-part 1722 with the second waterproof membrane 162 can provide better water-blocking effect for the side antenna 140. That is, when one of them fails, the other can still provide water-blocking effect, 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 membrane 162 extends further to the back of the glass substrate 110 in the non-display area NA. In this way, the second waterproof membrane 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 membrane 162 extends further to the surface of the first encapsulation sub-part 1721 in the non-display area NA, away from the glass substrate 110. In this way, the second waterproof membrane 162 can better cover the corner of the second encapsulation layer 172 from the side to the light-emitting surface, thus providing 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 encapsulation sub-part may be provided to cover the antenna.

[0089] A second aspect of this application provides a display module 20, see reference. 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 adhesive 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 adhesive 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 adhesive 220 away from the glass substrate 110.

[0090] Specifically, the polarizer 210 is disposed 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 adhesive 220 is a transparent adhesive material that allows the polarizer 210 and the cover plate 230 to be bonded together.

[0091] In one embodiment, see further. Figure 8 The display module 20 also includes a second light-shielding portion 240, which is located at least on the sidewall 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 beyond the edge of the optical adhesive 220.

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

[0093] Preferably, the material of the second light-shielding part 240 includes black adhesive, for example, it can be an acrylic, silicone, fluorine and polyurethane material.

[0094] In one embodiment, see Figure 9 The second light-shielding portion 240 is located on the sidewalls of all film layers between the glass substrate 110 and the optical adhesive 220. The second light-shielding portion 240 completely fills the sidewalls of the other film layers except for the cover plate 230, which helps to improve the sidewall's light-proofing effect.

[0095] In one embodiment, see Figure 10 The edge of the optical adhesive 220 is provided with a groove, and the second light-shielding part 240 is filled into the groove.

[0096] Specifically, since the display panel 10 has a non-display border area, in order to enhance the light-blocking effect in the non-display border area, the optical adhesive 220 has a groove in its edge, and the second light-blocking part 240 is filled into the groove. The second light-blocking part 240 in the groove can block the light from 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, the edge of the polarizer is provided with a groove, and the second light-shielding part fills the groove of the polarizer.

[0098] In one embodiment, see Figure 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 on the same layer as the optical adhesive 220 layer and at least partially fills the groove. The second light-shielding sub-portion 242 is located on the sidewall of the polarizer 210 and the display panel 10. The first light-shielding sub-portion 241 is located in the groove of the optical adhesive 220 and its main function is to block light leakage from the non-display area of ​​the light-emitting surface. The second light-shielding sub-portion 242 is located on the sidewall of the polarizer 210 and the display panel 10 and its main function is to block light leakage from the sides. Of course, the portion of the first light-shielding sub-portion 241 that is not located in the groove of the optical adhesive 220 can also block light leakage from the sides.

[0099] Furthermore, in some embodiments, considering that the second light-shielding part 240 is prepared by a coating process, and the final shape of the second light-shielding part 240 is not composed of multiple rectangles, the second light-shielding part 240 will form a structure with a certain taper angle, which will reduce the light-shielding effect. Based on this, in order to achieve a better light-shielding effect, the following embodiments are provided.

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

[0101] Specifically, the stacking direction refers to the direction in which the polarizer 210, optical adhesive 220, and cover plate 230 are stacked. Because the coating process causes the final first light-shielding sub-part 241 to form a taper angle, i.e., a first slope, on the surface away from the optical adhesive 220, the light-shielding effect of the first light-shielding sub-part 241 decreases. In this embodiment, the angle θ1 between the first slope and the stacking direction of the film layers in the display module 20 is further set to be greater than a first preset angle, thereby ensuring the light-shielding effect of the first light-shielding sub-part 241. The first preset angle is greater than or equal to 50 degrees, preferably greater than or equal to 54 degrees. For example, the first preset angle can be 50 degrees, 54 degrees, or 80 degrees, etc.

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

[0103] Specifically, the stacking direction refers to the direction in which the polarizer 210, optical adhesive 220, and cover plate 230 are stacked. Due to the coating process, the final second light-shielding sub-part 242 forms a taper angle, i.e., a second slope, on the surface away from the polarizer 210 and display panel 10. This reduces the light-shielding effect of the second light-shielding sub-part 242. In this embodiment, the angle θ2 between the second slope and the stacking direction of the film layers in the display module 20 is less than a second preset angle, thereby ensuring the light-shielding effect of the second light-shielding sub-part 242. The second preset angle is less than or equal to 40 degrees; 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, etc.
