Since the first conductive ring is arranged on the same side of the polarization function layer, the static electricity on the polarization function layer can be quickly gathered on the first conductive ring. Similarly, the static electricity on the phase compensation layer can also be quickly gathered on the second conductive ring on the same side of the phase compensation layer. The first conductive ring and the second conductive ring connected electrically can be grounded to conduct and discharge the static electricity on the first conductive ring and the second conductive ring. The static electricity on the polarizing sheet is prevented from damaging the film layer in the polarizing sheet, thereby preventing the function failure of the polarizing sheet. Moreover, the corrosion of the polarizing sheet caused by the dust or impurities adsorbed by the static electricity can be reduced, the aging of the polarizing sheet can be slowed down, and the optical performance of the polarizing sheet can be ensured.

[0049] This application provides a polarizer, a display panel, and an electronic device. Because a first conductive ring is disposed on the same side of the polarization functional layer, static electricity on the polarization functional layer can quickly accumulate on the first conductive ring. Similarly, static electricity on the phase compensation layer will also quickly accumulate on a second conductive ring on the same side as the phase compensation layer. The electrically connected first and second conductive rings can be grounded to conduct and discharge the static electricity on both rings. This prevents static electricity from damaging the film layers in the polarizer, thereby preventing polarizer malfunction. Furthermore, it reduces the corrosion of the polarizer by dust or impurities attracted by static electricity, slows down polarizer aging, and ensures the optical performance of the polarizer.

[0063] Please refer to Figure 1 and Figure 2 , Figure 1 This paper shows a schematic diagram of the film structure of a polarizer 20 provided in an embodiment of this application. Figure 2 Example Figure 1 A schematic diagram of the regional distribution of the substrate layer 203. In this embodiment, the polarizer 20 includes a substrate layer 203, a polarization functional layer 201, and a phase compensation layer 205. The substrate layer 203 includes a first side and a second side disposed opposite to each other. The polarization functional layer 201 is located on the first side of the substrate layer 203 and is used to convert ambient light into polarized light. The phase compensation layer 205 is located on the second side of the substrate layer 203 and is used to compensate for the phase of the light. The substrate layer 203 includes a film bonding area 2032 and a protruding area 2031 surrounding the film bonding area 2032. The orthogonal projections of the polarization functional layer 201 and the phase compensation layer 205 onto the substrate layer 203 are located in the film bonding area 2032. In this embodiment, the protruding area 2031 can be an annular region surrounding the film bonding area 2032. For example, when the film bonding area 2032 is a rectangular region, the shape of the protruding area 2031 can be a rectangular ring; when the film bonding area 2032 is a circular region, the shape of the protruding area 2031 can be a circular ring. The polarizer 20 also includes a first conductive ring 202 and a second conductive ring 204 electrically connected to each other. The first conductive ring 202 is distributed on the protruding area 2031 on the first side of the substrate layer 203, and the first conductive ring 202 surrounds the polarization functional layer 201. The second conductive ring 204 is distributed in the protruding area 2031 on the second side of the substrate layer 203, and the second conductive ring 204 surrounds the phase compensation layer 205.

[0064] In this context, polarizer 20 refers to an optical thin film capable of converting natural light into linearly polarized light, or selectively transmitting or blocking linearly polarized light. Polarizer 20 can be an absorptive polarizer 20, a reflective polarizer 20, or a wire-grid polarizer 20; the type of polarizer 20 is not specifically limited here. Polarization functional layer 201 is a film layer in polarizer 20 used to convert natural light into linearly polarized light in a specific direction. Polarization functional layer 201 can be an iodine-based polarization layer, a dye-based polarization layer, or a metal wire-grid polarization layer; the material of polarization functional layer 201 is not specifically limited here. Phase compensation layer 205 refers to a film layer capable of converting linearly polarized light into circularly polarized light, and circularly polarized light into linearly polarized light. For example, phase compensation layer 205 can perform quarter-wavelength phase compensation.

[0065] In this embodiment, the first conductive ring 202 can be used to transmit static electricity on the side where the polarization functional layer 201 is located. Exemplarily, the first conductive ring 202 can be a metal ring, a conductive rubber ring, or a conductive coating ring; the material of the first conductive ring 202 is not specifically limited here. The first conductive ring 202 may or may not be in contact with the polarization functional layer 201. The second conductive ring 204 can be used to transmit static electricity on the side where the phase compensation layer 205 is located. Exemplarily, the second conductive ring 204 can be a metal ring, a conductive rubber ring, or a conductive coating ring. The material of the first conductive ring 202 can be the same as or different from the material of the second conductive ring 204; the material of the second conductive ring 204 is not specifically limited here. The second conductive ring 204 may or may not be in contact with the phase compensation layer 205; the positional relationship between the first conductive ring 202 and the polarization functional layer 201, and the positional relationship between the second conductive ring 204 and the phase compensation layer 205, are not specifically limited here.

[0066] In a possible implementation of this embodiment, the first conductive ring 202 and the second conductive ring 204 can be connected by separate wires, or they can be directly connected together. Preferably, the first conductive ring 202 and the second conductive ring 204 are directly connected together, so that it is not necessary to separately manufacture wires for connecting the two. For example, through holes or notches can be formed in the substrate layer 203, and the first conductive ring 202 is electrically connected to the second conductive ring 204 through the through holes or notches. In this embodiment, the orthographic projection of the first conductive ring 202 on the substrate layer 203 and the orthographic projection of the second conductive ring 204 on the substrate layer 203 at least partially overlap. A through hole or notch is provided at the overlapping position, so that the first conductive ring 202 is directly electrically connected to the second conductive ring 204 through the through hole or notch.

[0067] In this embodiment, since a first conductive ring 202 is provided on the same side of the polarization functional layer 201, the first conductive ring 202 can quickly accumulate static electricity on the polarization functional layer 201. Similarly, static electricity on the phase compensation layer 205 will also quickly accumulate on the second conductive ring 204 on the same side as the phase compensation layer 205. The electrically connected first conductive ring 202 and second conductive ring 204 can be grounded to conduct and discharge the static electricity on the first conductive ring 202 and the second conductive ring 204. This avoids static electricity on the polarizer 20 from damaging the film layer in the polarizer 20, thereby preventing the polarizer 20 from malfunctioning. Moreover, it can also reduce the corrosion of the polarizer 20 by dust or impurities attracted by static electricity, slow down the aging of the polarizer 20, and ensure the optical performance of the polarizer 20.

[0068] In the above structure, since the first conductive ring 202 surrounds the polarization functional layer 201 and the second conductive ring 204 surrounds the phase compensation layer 205, the polarization functional layer 201 and the phase compensation layer 205 can be prevented from being affected by external water vapor in the polarizer 20, which would cause the polarization functional layer 201 to fail. The first conductive ring 202 and the second conductive ring 204 also play a role in preventing water vapor from intruding and causing the film layer in the polarizer 20 to fail.

[0069] Please refer to Figure 3 In one possible embodiment of this application, the polarizer 20 further includes a protective layer 206, a first pressure-sensitive adhesive layer 207, and a second pressure-sensitive adhesive layer 208. The protective layer 206 is located on the side of the polarization functional layer 201 away from the substrate layer 203. The first pressure-sensitive adhesive layer 207 is located between the phase compensation layer 205 and the substrate layer 203. The second pressure-sensitive adhesive layer 208 is located on the side of the phase compensation layer 205 away from the substrate layer 203. In this embodiment, the orthographic projections of the protective layer 206, the first pressure-sensitive adhesive layer 207, and the second pressure-sensitive adhesive layer 208 onto the substrate layer 203 are all located in the film bonding area 2032. Optionally, in this embodiment, the corresponding sides of the protective layer 206 and the polarization functional layer 201 are flush, meaning that the orthographic projection of the protective layer 206 onto the substrate layer 203 and the orthographic projection of the polarization functional layer 201 onto the substrate layer 203 completely overlap. Optionally, the corresponding sides of the first pressure-sensitive adhesive layer 207, the phase compensation layer 205, and the second pressure-sensitive adhesive layer 208 are also flush, and the orthographic projections of the first pressure-sensitive adhesive layer 207, the phase compensation layer 205, and the second pressure-sensitive adhesive layer 208 on the substrate layer 203 are also completely overlapping.

[0070] In this embodiment, the protective layer 206 is used to protect the polarization functional layer 201. The protective layer 206 primarily enhances the scratch resistance of the polarizer 20, preventing the polarization functional layer 201 from being scratched, worn, or corroded. For example, the protective layer 206 can be a hardened coating. The protective layer 206 completely covers one side of the polarization functional layer 201 away from the substrate layer 203, achieving comprehensive protection for the polarization functional layer 201. Furthermore, the protective layer 206 is flush with the corresponding sides of the polarization functional layer 201, preventing light leakage from the edges of the polarization functional layer 201 and improving display contrast.

[0071] In this embodiment, the phase compensation layer 205 is located between the first pressure-sensitive adhesive layer 207 and the second pressure-sensitive adhesive layer 208. The side of the first pressure-sensitive adhesive layer 207 away from the phase compensation layer 205 is bonded to the substrate layer 203. The second pressure-sensitive adhesive layer 208 can be used to bond the polarizer 20 to other devices, such as the display screen 30. The pressure-sensitive adhesive layer is a material that can generate adhesion under slight pressure and can firmly bond without solvents, heating, or chemical reactions. The type of pressure-sensitive adhesive can be silicone-based, rubber-based, or acrylic-based; the specific type of pressure-sensitive adhesive is not limited here.

[0072] In this embodiment, the edges of the first pressure-sensitive adhesive layer 207, the phase compensation layer 205, and the second pressure-sensitive adhesive layer 208 are flush, which can avoid stress concentration at the edges of each layer and reduce the risk of warping or delamination.

[0073] Please refer to this again. Figure 3 Furthermore, the first conductive ring 202 can contact the sides of the protective layer 206 and the polarization functional layer 201, and the second conductive ring 204 can contact the sides of the first pressure-sensitive adhesive layer 207, the phase compensation layer 205, and the second pressure-sensitive adhesive layer 208. Preferably, the side of the first conductive ring 202 away from the substrate layer 203 is flush with the side of the protective layer 206 away from the substrate layer 203, and the side of the second conductive ring 204 away from the substrate layer 203 is flush with the side of the second pressure-sensitive adhesive layer 208 away from the substrate layer 203. That is, in the plane perpendicular to the substrate layer 203, the thickness of the first conductive ring 202 is equal to the sum of the film thicknesses of the polarization functional layer 201 and the protective layer 206, and the thickness of the second conductive ring 204 is equal to the sum of the film thicknesses of the first pressure-sensitive adhesive layer 207, the phase compensation layer 205, and the second pressure-sensitive adhesive layer 208.

[0074] In this embodiment, the first conductive ring 202 contacts the side of the protective layer 206 and the polarization functional layer 201, which can quickly discharge static electricity on the first side of the substrate layer 203 to avoid electrostatic breakdown of the fragile polarization functional layer 201. In this embodiment, the polarization functional layer 201 is highly susceptible to moisture, which can lead to hydrolysis of the film material and loss of function of the polarization functional layer 201. Since the first conductive ring 202 contacts the side of the polarization functional layer 201, the first conductive ring 202 can act as a side sealing barrier for the polarization functional layer 201, preventing moisture from the side from invading into the polarization functional layer 201 and protecting the polarization functional layer 201 from damage caused by moisture intrusion. Similarly, the second conductive ring 204 contacts the side of the first pressure-sensitive adhesive layer 207, the phase compensation layer 205, and the second pressure-sensitive adhesive layer 208. The second conductive ring 204 can also act as a side sealing barrier for the phase compensation layer 205, preventing moisture from the side from invading into the phase compensation layer 205 and protecting the phase compensation layer 205 from the effects of moisture intrusion.

[0075] Please see Figure 4 , Figure 4 This illustration shows the distribution of the second conductive ring 204 in the polarizer 20 provided in this embodiment. Further, the polarizer 20 also includes a conductive portion 209, which is disposed on the side of the second conductive ring 204 away from the film bonding area 2032, and protrudes from the second conductive ring 204 in a direction away from the film bonding area 2032. Exemplarily, there can be multiple conductive portions 209, which can be located on the same side of the second conductive ring 204. In this embodiment, the conductive portion 209 and the second conductive ring 204 can be made of the same conductive material or different conductive materials; that is, the conductive portion 209 and the second conductive ring 204 can be manufactured using the same process or different processes. Preferably, the conductive portion 209 and the second conductive ring 204 are manufactured using the same process; specifically, the conductive portion 209 and the second conductive ring 204 can be integrally formed.

[0076] In this embodiment, the conductive part 209 can be used to connect to a grounding trace or a grounding terminal. Static electricity on the first conductive ring 202 and the second conductive ring 204 can be discharged through the conductive part 209 to the grounding trace or grounding terminal. The material of the conductive part 209 can be a conductive metal or a rubber with conductive function; the material of the conductive part 209 is not specifically limited here.

[0077] The conductive portion 209 protrudes away from the film bonding area 2032 relative to the second conductive ring 204, ensuring a large contact area between the conductive portion 209 and the grounding trace or grounding terminal. This reduces contact resistance and improves the stability of electrostatic discharge. Furthermore, the protruding structure of the conductive portion 209 avoids physical interference between the conductive portion 209 and other films in the polarizer 20, reducing the risk of short circuits or mechanical damage.

[0078] Furthermore, the shape of the conductive part 209 can be rectangular or semi-circular; the shape of the conductive part 209 is not specifically limited here. In this embodiment, multiple conductive parts 209 are concentrated on the same side of the second conductive ring 204, which facilitates centralized connection with the grounding line or grounding terminal, thereby improving the static discharge efficiency.

[0079] The inventors discovered through research that after copper rod friction or electrostatic testing of the display panel 1, if the static electricity is not discharged or eliminated in time, the edges of the screen will become bright and greenish, gradually turning the entire surface green, eventually causing defects such as image retention, bright spots, and flickering, affecting product quality. Furthermore, the polarization functional layer 201 of the polarizer 20 on the display panel 1 is extremely prone to hydrolysis and failure. Although the polarization functional layer 201 is protected by a protective layer 206 on top and a substrate layer 203 on the bottom, moisture can easily enter from the sides of the polarization functional layer 201, affecting its normal operation and consequently impacting the display of the display panel 1.

[0080] To solve the above problems, based on the same inventive concept, please refer to... Figure 5 This embodiment also provides a display panel 1, which includes a display screen body 30, a polarizer 20, and a cover plate 10. The polarizer 20 is located on the light-emitting surface side of the display screen body 30, and the cover plate 10 is located on the side of the polarizer 20 away from the display screen body 30.

[0081] In this embodiment, please refer again. Figure 1 and Figure 2The polarizer 20 includes a substrate layer 203, a polarization functional layer 201, and a phase compensation layer 205. The substrate layer 203 includes a first side and a second side disposed opposite to each other. The polarization functional layer 201 is located on the first side of the substrate layer 203 and is used to convert ambient light into polarized light. The phase compensation layer 205 is located on the second side of the substrate layer 203 and is used to compensate for the phase of the light. The substrate layer 203 includes a film bonding area 2032 and a protruding area 2031 surrounding the film bonding area 2032. The orthogonal projections of the polarization functional layer 201 and the phase compensation layer 205 onto the substrate layer 203 are located in the film bonding area 2032. In this embodiment, the protruding area 2031 can be an annular region surrounding the film bonding area 2032. For example, when the film bonding area 2032 is a rectangular region, the shape of the protruding area 2031 can be a rectangular ring; when the film bonding area 2032 is a circular region, the shape of the protruding area 2031 can be a circular ring. The polarizer 20 also includes a first conductive ring 202 and a second conductive ring 204 electrically connected to each other. The first conductive ring 202 is distributed on the protruding area 2031 on the first side of the substrate layer 203, and the first conductive ring 202 surrounds the polarization functional layer 201. The second conductive ring 204 is distributed in the protruding area 2031 on the second side of the substrate layer 203, and the second conductive ring 204 surrounds the phase compensation layer 205.

[0082] The display body 30 refers to the core functional part of the display screen, which is the physical carrier for displaying images. The cover plate 10 refers to the outermost protective layer 206 of the display panel 1, which is used to protect the display panel 1 from physical damage and provide a clear display effect. For a detailed explanation of the polarizer 20, please refer to the detailed description in the foregoing embodiments, and it will not be repeated here.

[0083] In this embodiment, the first conductive ring 202 surrounds the polarization functional layer 201, enabling rapid collection of static electricity on the polarization functional layer 201. Similarly, the second conductive ring 204 surrounds the phase compensation layer 205, also enabling rapid collection of static electricity on the phase compensation layer 205. The first conductive ring 202 and the second conductive ring 204 are electrically connected through the substrate layer 203, allowing for rapid discharge of static electricity from opposite sides of the polarizer. This prevents static electricity accumulation from affecting the display panel 1 and causing defects such as green screen, image retention, bright spots, and flicker, thus ensuring the display effect of the display panel 1 and enhancing its market competitiveness.

[0084] Please see Figure 6 , Figure 6A schematic diagram of the ink distribution in the cover plate 10 of the display panel 1 is shown. Further, the cover plate 10 includes a light-transmitting area 101 and an ink area 102 surrounding the light-transmitting area 101. Specifically, the ink area 102 surrounds the light-transmitting area 101. For example, when the light-transmitting area 101 is a rectangular region, the ink area 102 can be a rectangular ring; when the light-transmitting area 101 is a circular region, the ink area 102 can be a circular ring. In this embodiment, the light-transmitting area 101 transmits the light emitted by the display screen 30, and the ink area 102 blocks the light emitted by the display screen 30, so that the image is displayed within a limited display area.

[0085] Furthermore, the light-transmitting area 101 on the cover plate 10 can overlap with the film bonding area 2032 of the substrate layer 203 in the polarizer 20, and the ink area 102 on the cover plate 10 can overlap with the protruding area 2031 of the substrate layer 203 in the polarizer 20.

[0086] In this embodiment, the orthographic projections of the first conductive ring 202 and the second conductive ring 204 on the cover plate 10 are located within the ink area 102. That is, the width of the first conductive ring 202 and the second conductive ring 204 is less than or equal to the width of the ink area 102. This design avoids the first conductive ring 202 and / or the second conductive ring 204 from being exposed relative to the ink area 102, and avoids light leakage or glare at the edge of the display panel 1 caused by reflection from the first conductive ring 202 and / or the second conductive ring 204, thus ensuring the optical consistency between the display area and the edge. The ink area 102 absorbs stray light, and the first conductive ring 202 and the second conductive ring 204 are hidden within the ink area 102, which can further reduce light scattering.

[0087] In this embodiment, the display screen 30 includes an array driving layer and a light-emitting device layer located on the array driving layer. The array driving layer includes a substrate, a plurality of conductive layers located on the substrate, and an insulating layer located between adjacent conductive layers. Pixel circuits (e.g., 3T1C circuits or 7T1C circuits) are formed in the array driving layer. The light-emitting device layer includes light-emitting devices arranged in an array. For example, the light-emitting devices include red, blue, and green light-emitting devices with different emitting colors. An adjacent red, blue, and green light-emitting device constitutes a pixel unit. The display panel 1 is composed of a plurality of pixel units arranged in an array. The pixel circuits in the array driving layer are connected to the light-emitting devices, and the pixel circuits drive the light-emitting devices to emit light to present the display image on the display panel 1.

[0088] Please refer to Figure 5 and Figure 7In this embodiment, the display panel 1 includes a display area, a bending area 301, and a bonding area. The bonding area is connected to the display area via the bending area 301 and can be bent to one side of the display area via the bending area 301. The display panel 1 includes a bonding electrode 302 located in the bonding area. The bonding electrode 302 is used to bond with the gold fingers on the flexible circuit board 303 (FPC) to achieve signal transmission. The bonding electrode 302 can be formed by a conductive layer in the array driving layer. For example, when the array driving layer includes a first conductive layer, a second conductive layer, a third conductive layer, and a fourth conductive layer stacked together, the bonding electrode 302 can be formed by the fourth conductive layer.

[0089] Furthermore, in this embodiment, the display body 30 may also include a bonding contact 3021, which may be located on the side of the display area of ​​the display body 30 facing the bonding area. The bonding contact 3021 may be disposed in the same layer as the bonding electrode 302, that is, the two may be formed by the same conductive layer in the array driving layer.

[0090] Furthermore, the polarizer 20 also includes a conductive portion 209, which is disposed on the side of the second conductive ring 204 away from the film bonding area 2032, and the conductive portion 209 protrudes relative to the second conductive ring 204 in a direction away from the film bonding area 2032; the display body 30 includes a bonding contact 3021, and the conductive portion 209 contacts the bonding contact 3021; ​​preferably, the display body 30 also includes a bonding electrode 302, and the bonding contact 3021 and the bonding electrode 302 are disposed in the same layer.

[0091] In this embodiment, the conductive portion 209 of the polarizer 20 protrudes from the second conductive ring 204 away from the film bonding area 2032, forming a physically extended conductive path, and directly contacts the bonding contact 3021 of the display body 30, without the need for additional adapter components. Moreover, the direct contact between the conductive portion 209 and the bonding contact 3021 reduces signal attenuation caused by intermediate interfaces and ensures efficient static discharge.

[0092] Furthermore, the display panel 1 also includes an optical adhesive layer 40, which is located between the polarizer 20 and the cover plate 10. Please refer to [reference needed]. Figure 3The polarizer 20 further includes a protective layer 206, a first pressure-sensitive adhesive layer 207, and a second pressure-sensitive adhesive layer 208. The protective layer 206 is located on the side of the polarization functional layer 201 away from the substrate layer 203. The first pressure-sensitive adhesive layer 207 is located between the phase compensation layer 205 and the substrate layer 203. The second pressure-sensitive adhesive layer 208 is located on the side of the phase compensation layer 205 away from the substrate layer 203. In this embodiment, the orthographic projections of the protective layer 206, the first pressure-sensitive adhesive layer 207, and the second pressure-sensitive adhesive layer 208 onto the substrate layer 203 are all located in the film bonding area 2032. Optionally, in this embodiment, the corresponding sides of the protective layer 206 and the polarization functional layer 201 are flush, meaning that the orthographic projections of the protective layer 206 and the polarization functional layer 201 onto the substrate layer 203 completely overlap. Optionally, the corresponding sides of the first pressure-sensitive adhesive layer 207, the phase compensation layer 205, and the second pressure-sensitive adhesive layer 208 are also flush, and the orthographic projections of the first pressure-sensitive adhesive layer 207, the phase compensation layer 205, and the second pressure-sensitive adhesive layer 208 on the substrate layer 203 are also completely overlapping.

[0093] Please refer to this again. Figure 3 Furthermore, the first conductive ring 202 can contact the sides of the protective layer 206 and the polarization functional layer 201, and the second conductive ring 204 can contact the sides of the first pressure-sensitive adhesive layer 207, the phase compensation layer 205, and the second pressure-sensitive adhesive layer 208. Preferably, the side of the first conductive ring 202 away from the substrate layer 203 is flush with the side of the protective layer 206 away from the substrate layer 203, and the side of the second conductive ring 204 away from the substrate layer 203 is flush with the side of the second pressure-sensitive adhesive layer 208 away from the substrate layer 203. That is, in the plane perpendicular to the substrate layer 203, the thickness of the first conductive ring 202 is equal to the sum of the film thicknesses of the polarization functional layer 201 and the protective layer 206, and the thickness of the second conductive ring 204 is equal to the sum of the film thicknesses of the first pressure-sensitive adhesive layer 207, the phase compensation layer 205, and the second pressure-sensitive adhesive layer 208.

[0094] For details, please refer to [link / reference]. Figure 5 The display panel 1 also includes a composite tape layer 50 and a support film layer 60. The support film layer 60 is located on the side of the display body 30 away from the polarizer 20, and the composite tape layer 50 is located on the side of the support film layer 60 away from the display body 30.

[0095] The optical adhesive layer 40 is a transparent adhesive material in the display panel 1, located between the polarizer 20 and the cover plate 10, used for bonding, filling gaps, and optimizing optical performance. The optical adhesive layer 40 can be a solid optical adhesive, a liquid optical adhesive, or a pressure-sensitive adhesive; the specific type of the optical adhesive layer 40 is not limited here.

[0096] Furthermore, the composite tape layer 50 refers to a tape structure made of multiple materials through a composite process. For example, the composite tape layer 50 may be a polyester film (PET). In this embodiment, the support film layer 60 is a thin film layer used to provide mechanical support for the display screen body 30.

[0097] In this embodiment, the optical adhesive layer 40 is located between the polarizer 20 and the cover plate 10, which can improve light transmittance and reduce reflection. A protective layer 206 is provided on the outermost layer of the polarizer 20 to protect the polarization functional layer 201 from scratches, wear, or chemical corrosion. The first pressure-sensitive adhesive layer 207 is located between the phase compensation layer 205 and the substrate layer 203, which can fix the phase compensation layer 205 and the substrate layer 203. Since the second pressure-sensitive adhesive layer 208 is located on the side of the phase compensation layer 205 away from the substrate layer 203, it can be used for heat dissipation of the polarizer 20 and for fixing the polarizer 20 and the display screen body 30. The function of the second pressure-sensitive adhesive layer 208 is not limited here.

[0098] By aligning the corresponding sides of the protective layer 206 and the polarization functional layer 201, as well as the corresponding sides of the first pressure-sensitive adhesive layer 207, the phase compensation layer 205, and the second pressure-sensitive adhesive layer 208, edge effects on the polarizer 20 can be reduced, improving overall performance. Furthermore, the contact between the first conductive ring 202 and the sides of the protective layer 206 and the polarization functional layer 201, and the contact between the second conductive ring 204 and the sides of the protective layer 206, the first pressure-sensitive adhesive layer 207, and the second pressure-sensitive adhesive layer 208, allows for the rapid collection of static electricity on the display panel 1 that cannot be discharged due to the insulating film layers such as the optical adhesive layer 40 and the composite tape layer 60, facilitating the discharge of static electricity on the display panel 1. Furthermore, the side of the first conductive ring 202 away from the substrate layer 203 is flush with the side of the protective layer 206 away from the substrate layer 203, and the side of the second conductive ring 204 away from the substrate layer 203 is flush with the side of the second pressure-sensitive adhesive layer 208 away from the substrate layer 203. This design can prevent the polarizer 20 from being affected by edge stress, thus avoiding edge warping or delamination.

[0099] The display panel 1 provided above has a first conductive ring 202 disposed around the polarization functional layer 201 of the polarizer 20 and a second conductive ring 204 disposed around the phase compensation layer 205 of the polarizer 20. The first conductive ring 202 and the second conductive ring 204 are electrically connected, and a conductive portion 209 integrally formed with the second conductive ring 204 protrudes from the second conductive ring 204 away from the film bonding area 2032 and is connected to the bonding contact 3021 of the display panel 1. In this way, the first conductive ring 202 can quickly accumulate static electricity on the polarization functional layer 201, and the static electricity on the polarization functional layer 201 can be transferred to the second conductive ring 204 by utilizing the electrical connection between the first conductive ring 202 and the second conductive ring 204. At the same time, the second conductive ring 204 not only receives the static electricity transmitted by the first conductive ring 202, but also accumulates the static electricity on the phase compensation layer 205, and transmits the obtained static electricity to the bonding contact 3021 of the display panel 1 through the conductive part 209, so as to discharge the static electricity on the polarizer 20, improve the anti-static capability of the polarizer 20, and further protect the polarizer 20 and the display effect of the display panel 1.

[0100] Based on the same inventive concept, this embodiment also provides an electronic device, which includes multiple display panels 1 as described in the previous embodiments. A first conductive ring 202 is disposed around the polarization functional layer 201 of the polarizer 20 on the display panel 1, and a second conductive ring 204 is disposed around the phase compensation layer 205 of the polarizer 20. The first conductive ring 202 and the second conductive ring 204 are electrically connected, and a conductive portion 209 integrally formed with the second conductive ring 204 protrudes from the second conductive ring 204 away from the film bonding area 2032, and is connected to the bonding contacts 3021 of the display panel 1. In this way, the first conductive ring 202 can quickly accumulate static electricity on the polarization functional layer 201, and utilize the electrical connection between the first conductive ring 202 and the second conductive ring 204 to transfer the static electricity on the polarization functional layer 201 to the second conductive ring 204. Meanwhile, the second conductive ring 204 not only receives the static electricity transmitted from the first conductive ring 202, but also accumulates static electricity on the phase compensation layer 205. This static electricity is then transmitted through the conductive part 209 to the bonding contact 3021 of the display panel 1 to discharge static electricity from the polarizer 20, thereby improving the anti-static capability of the polarizer 20 and further protecting the polarizer 20 and the display effect of the display panel 1. Because the polarizer 20 has the characteristic of rapid static electricity discharge, it can improve the anti-static capability of the display panel 1, thus ensuring the display effect of the display panel 1.

[0101] In summary, the polarizer 20, display panel 1, and electronic device provided in this embodiment, due to the presence of a first conductive ring 202 on the same side of the polarization functional layer 201, allow static electricity on the polarization functional layer 201 to quickly accumulate on the first conductive ring 202. Similarly, static electricity on the phase compensation layer 205 will also quickly accumulate on the second conductive ring 204 on the same side as the phase compensation layer 205. The electrically connected first conductive ring 202 and second conductive ring 204 can be grounded to conduct and discharge the static electricity on the first conductive ring 202 and the second conductive ring 204. This avoids static electricity on the polarizer 20 from damaging the film layer in the polarizer 20, thereby preventing the polarizer 20 from malfunctioning. Furthermore, it can reduce the corrosion of the polarizer 20 by dust or impurities attracted by static electricity, slow down the aging of the polarizer 20, and ensure the optical performance of the polarizer 20.
