Abstract
Description
Technical Field
[0001] The present application relates to the field of display, and in particular to a display panel and a display device. Background Art
[0002] In the field of semiconductor displays, electrostatic discharge is a common phenomenon that may cause damage to the display panel or performance degradation. First, electrostatic discharge will generate high voltage on the surface of the display panel, which may cause the material on the surface of the display panel to be broken down, thus affecting the display effect. For example, electrostatic discharge may cause damage to the pixels on the display panel, resulting in residual images, bright spots or dark spots on the display screen. Secondly, electrostatic discharge may cause damage to electronic components on the surface of the display panel, such as thin-film transistors and driver chips. These components are very sensitive to electrostatic discharge. Once affected by electrostatic discharge, the performance of the components may be degraded, fail or even damaged, resulting in a decline in the overall performance of the display panel or even complete failure.

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 those skilled in the art without creative work are within the scope of protection of the present application.

[0032] The embodiments of the present application provide a display panel and a display device, which are described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.
[0033] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of the first display panel provided in the embodiment of the present application. Figure 1 As shown, the display panel 100 includes a display substrate 110, which is used as the display body of the display panel 100 and is used to control the display screen of the display panel 100 and display it. Among them, a grounding terminal 111 is provided on the display substrate 110, which is used to conduct part of the charge to the ground; when the display panel 100 is a liquid crystal display panel 100, the display panel 100 includes an array substrate and a color film substrate arranged oppositely, and the grounding terminal 111 is arranged on the array substrate. The display panel 100 in the embodiment of the present application can also be of other types, and there is no special limitation here.
[0034] The display panel 100 includes a polarizer 120 and a conductive connection portion 130. The polarizer 120 is arranged on the display side of the display substrate 110, and is used to adjust the outgoing light of the display substrate 110, so as to adjust the display screen of the display panel 100. The polarizer 120 includes a first adhesive layer 121 and an optical function layer 122 which are arranged in sequence in a direction away from the display substrate 110. The first adhesive layer 121 is a pressure-sensitive adhesive layer, which is used to bond with the display side of the display substrate 110 to achieve the bonding of the polarizer 120 and the display substrate 110; the optical function layer 122 is composed of a multi-layer film stack, wherein the optical function layer 122 includes at least one conductive layer 123, and the conductive layer 123 is electrically connected to the ground terminal 111 through the conductive connection portion 130.
[0035] The conductive connection part 130 can be a conductive material such as conductive silver paste or conductive glue, and the specific material type can be selected and adjusted according to actual design requirements, and is not particularly limited here.
[0036] Since static electricity is generated on the surface of the display panel 100 during use, electrostatic discharge will generate high voltage on the surface of the display panel 100, which may cause the material on the surface of the display panel 100 to be broken down, and may even cause damage to the pixels on the display panel 100, resulting in residual images, bright spots or dark spots on the display screen, affecting the display effect of the display panel 100. In addition, electrostatic discharge may also cause damage to electronic components on the surface of the display panel 100, such as thin film transistors, driver chips, etc. These components are very sensitive to electrostatic discharge. Once affected by electrostatic discharge, the performance of the components may be reduced, fail, or even be damaged, thereby causing the overall performance of the display panel 100 to be reduced, or even completely fail, affecting the normal use of the display panel 100.
[0037] In the embodiment of the present application, at least one layer of the optical function layer 122 in the polarizer 120 is set as the conductive layer 123, and the conductive layer 123 is electrically connected to the ground terminal 111 of the display substrate 110 by using the conductive connection part 130, so that when static electricity is generated on the surface of the display panel 100, the static electricity can be conducted to the ground terminal 111 on the display substrate 110 through the conductive layer 123 in the polarizer 120 and the conductive connection part 130, and then conducted out from the ground terminal 111, so as to improve the anti-static ability of the display panel 100 and reduce the influence of static electricity discharge on the performance and display effect of the display panel 100. In addition, since the optical function layer 122 in the polarizer 120 is located in the area of the display panel 100 close to the surface of the display panel 100, by setting at least one layer of the optical function layer 122 as the conductive layer 123, it is also more conducive to the conduction of static electricity on the surface of the display panel 100.
[0038] Please continue reading Figure 1The optical function layer 122 includes a first protective layer 1221, a second adhesive layer 1222, a polarizing layer 1223, a third adhesive layer 1224, a second protective layer 1225 and a protective layer 1226 which are sequentially arranged in a direction away from the first adhesive layer 121, at least one of which is arranged as a conductive layer 123. In this embodiment, the protective layer 1226 is arranged as a conductive layer 123 as an example for explanation. Of course, other layers may also be arranged as conductive layers 123, and no special limitation is made here. Figure 1 As shown, the protective layer 1226 is electrically connected to the ground terminal 111 through the conductive connecting portion 130, so that the static charge generated on the surface of the display panel 100 can be discharged along the protective layer 1226, the conductive connecting portion 130 and the ground terminal 111, thereby improving the anti-static ability of the display panel 100 and reducing the impact of electrostatic discharge on the performance of the display panel 100 and the display effect.
[0039] The polarizing layer 1223 is the core grid structure layer of the polarizer 120, which is made of polyvinyl alcohol (PVA) after dyeing to adsorb iodine molecules with biaxial absorption function, and then the iodine molecules are arranged in order on the PVA film by stretching, so as to form a polarizing layer 1223 with uniform biaxial absorption function, and its transmission axis is perpendicular to the stretching direction. The material of the first protective layer 1221 and the second protective layer 1225 includes but is not limited to one of optical resins such as polymethyl methacrylate, polyethylene terephthalate, polycarbonate, polytriacetyl cellulose, cycloolefin polymer, etc.; the first protective layer 1221 and the second protective layer 1225 serve as the support of the polarizing layer 1223, ensuring that the extension of the polarizing layer 1223 will not retract. In addition, the first protective layer 1221 and the second protective layer 1225 also have excellent ultraviolet resistance, acid and alkali resistance, so as to protect the polarizing layer 1223 from damage by external environmental factors such as water vapor and ultraviolet rays.
[0040] The materials of the second adhesive layer 1222 and the third adhesive layer 1224 include but are not limited to thermosetting acrylic resin adhesive or ultraviolet curing resin adhesive, the second adhesive layer 1222 is used to bond the polarizing layer 1223 and the first protective layer 1221, and the third adhesive layer 1224 is used to bond the polarizing layer 1223 and the second protective layer 1225. The protective layer 1226, as a surface coating of the polarizer 120, can be one or more of a hard coating, a high fog coating, an anti-reflective coating, or an anti-fingerprint coating, to ensure the stability and reliability of the polarizer 120 during use.
[0041] It should be noted that the conductive layer 123 contains multiple conductive particles, and the material of the conductive particles includes one or more of metal conductive particles, carbon-based conductive particles and metal oxide conductive particles. That is, by adding conductive particles to different film layers of the optical functional layer 122 of the polarizer 120 to reduce the impedance of the film layer, it is turned into a conductive layer 123, thereby achieving the purpose of conducting static electricity.
[0042] Specifically, the metal conductive particles include nano or micro particles such as silver, copper or gold, the carbon-based conductive particles include graphene or carbon black, and the metal oxide conductive particles include zinc oxide, indium oxide or indium tin oxide. The specific type of the particles can be selected and adjusted according to actual design requirements. It is only necessary to ensure that the conductive layer 123 after adding the conductive particles has sufficient conductivity to ensure the smooth discharge of static electricity. No special restrictions are made here.
[0043] The shapes of the conductive particles include spherical, square, linear or rod-shaped, etc. When the conductive particles are spherical, the radius of the conductive particles is greater than or equal to 1 nm and less than or equal to 100 μm. Specifically, the radius of the conductive particles can be designed to be 1 nm, 100 nm, 1 μm, 10 μm or 100 μm, etc., and particles of different radius sizes can also be mixed and dispersed in the corresponding film layer. It is only necessary to ensure that the conductive particles can be evenly dispersed in the corresponding conductive layer 123, and no special restrictions are made here.
[0044] When the shape of the conductive particles is square, the side length of the conductive particles is greater than or equal to 1nm and less than or equal to 100μm. Specifically, the side length of the conductive particles can be designed to be 1nm, 100nm, 1μm, 10μm or 100μm, etc., and particles of different side lengths can also be mixed and dispersed in the corresponding film layer. It is only necessary to ensure that the conductive particles can be evenly dispersed in the corresponding conductive layer 123. There is no special restriction here.
[0045] When the shape of the conductive particles is linear or rod-shaped, the length of the conductive particles is greater than or equal to 50nm and less than or equal to 100μm, and the aspect ratio of the conductive particles is greater than or equal to 20 and less than or equal to 10000. Specifically, the length of the conductive particles can be designed to be 50nm, 100nm, 1μm, 10μm or 100μm, etc., and the aspect ratio of the conductive particles can be designed to be 20, 100, 500, 1000, 5000 or 10000, etc. Particles of different lengths and aspect ratios can also be mixed and dispersed in the corresponding film layer. It is only necessary to ensure that the conductive particles can be evenly dispersed in the corresponding conductive layer 123, and there is no special restriction here.
[0046] It should be noted that the conductivity of the conductive layer 123 is related to the shape and size of the added conductive particles as well as the content of the conductive particles. If the content of the conductive particles is too low, the conductivity of the conductive layer 123 may be poor, and static electricity cannot be effectively and timely discharged. If the content of the conductive particles is too high, the dispersion uniformity of the conductive particles in the conductive layer 123 may be poor, thereby affecting the thickness uniformity or light transmittance uniformity of the polarizing layer 1223 as a whole, and further affecting the overall display effect of the display panel 100. In the embodiment of the present application, the mass fraction of the conductive particles in the conductive layer 123 is set to be greater than or equal to 0.001% and less than or equal to 50%. Specifically, the mass fraction of the conductive particles can be set to 0.001%, 0.01%, 0.1%, 1%, 10% or 50%, etc. The specific content can be selected and adjusted according to actual design requirements, and is not particularly limited here.
[0047] See also Figure 2 , Figure 2 This is a schematic diagram of the structure of the second display panel provided in the embodiment of the present application. Figure 2 As shown, in Figure 1 On the basis of the structure of the display panel 100 shown in , the optical functional layer 122 includes at least two conductive layers 123, and at least two adjacent conductive layers 123 are arranged at intervals. In this embodiment, the protective layer 1226 and the third adhesive layer 1224 are set as the conductive layer 123 as an example for explanation. Of course, other layers can also be set as the conductive layer 123, and there is no special limitation here. In this embodiment, at least two conductive layers 123 are set in the optical functional layer 122, and at least two adjacent conductive layers 123 are arranged at intervals, so that when static charge is generated on the surface of the display panel 100, the static charge can be discharged along the conductive layer 123 in the area with a closer distance, thereby facilitating the rapid discharge of static charge and reducing the risk of performance degradation or damage of components in the display panel 100.
[0048] Among them, at least two layers of conductive layers 123 are electrically connected to each other, that is, at least two layers of conductive layers 123 can be electrically connected to the corresponding grounding terminal 111 through the same conductive connecting part 130, so that when static electricity is generated on the surface of the display panel 100, no matter along which layer of the conductive layer 123 the static charge is conducted, it can be conducted along the conductive connecting part 130 to the grounding terminal 111 and be discharged from the grounding terminal 111, which helps to simplify the setting method of the conductive connecting part 130 and simplify the process of the display panel 100.
[0049] It should be noted that since the optical functional layer 122 of the polarizer 120 is a laminated structure, when different conductive layers 123 are electrically connected through the same conductive connecting part 130, the conductive connecting part 130 can be directly set on the side surface of the corresponding conductive layer 123, and the side surfaces of the corresponding different conductive layers 123 can be at least partially covered at the same time, and then the conductive connecting part 130 is electrically connected to the ground terminal 111, thereby realizing the electrical connection of different conductive layers 123 with the ground terminal 111 through the same conductive connecting part 130.
[0050] Please continue reading Figure 2 At least two grounding terminals 111 are provided on the display substrate 110, and the display panel 100 includes at least two conductive connecting parts 130. The conductive layers 123 are electrically connected to the grounding terminals 111 through the conductive connecting parts 130 in a one-to-one correspondence, that is, each conductive layer 123 is electrically connected to the corresponding grounding terminal 111 through the corresponding conductive connecting part 130, so that each conduction channel is independent of each other, thereby avoiding mutual interference between static charges in different conduction channels when the static charges generated on the surface of the display panel 100 are conducted, thereby affecting the derivation of static charges and the overall antistatic ability of the display panel 100.
[0051] It should be noted that from Figure 2 It can be seen that since the optical functional layer 122 of the polarizer 120 is a laminated structure, different conductive connecting parts 130 are electrically connected to the corresponding conductive layer 123 by partially covering the side surface of the polarizer 120. When one of the conductive connecting parts 130 is simultaneously arranged on the side surfaces of different conductive layers 123, it is necessary to perform insulation treatment between the conductive connecting part 130 and the other conductive layers 123, such as coating a layer of insulating layer (not shown in the figure) at the corresponding position between the conductive connecting part 130 and the side surface of the polarizer 120.
[0052] Specifically, Figure 2 In the example, the conductive layer 123 is taken as the protective layer 1226 and the third adhesive layer 1224, where one conductive connection part 130 is arranged at a position corresponding to the side surface of the third adhesive layer 1224, the polarizing layer 1223, the second adhesive layer 1222 and the first protective layer 1221, and the other conductive connection part 130 is arranged at a position corresponding to the side surface of the protective layer 1226, the second protective layer 1225, the third adhesive layer 1224, the polarizing layer 1223, the second adhesive layer 1222 and the first protective layer 1221. Since the conductive connection part 130 is arranged on the side surfaces of the protective layer 1226 and the third adhesive layer 1224 at the same time, it is necessary to coat an insulating layer (not shown in the figure) between the conductive connection part 130 and the third adhesive layer 1224 to insulate the conductive connection part 130 from the third adhesive layer 1224, thereby ensuring that the electrostatic charge conduction channels on the protective layer 1226 and the third adhesive layer 1224 are independent of each other.
[0053] See also Figure 3 and Figure 4 , Figure 3 A schematic diagram of the structure of a third display panel provided in an embodiment of the present application, Figure 4 Provided in the embodiments of this application Figure 3 A cross-sectional view of the panel is shown in FIG. Figure 3 and Figure 4 As shown, the display substrate 110 includes a display area S1 and a non-display area S2. The ground terminal 111 is located in the non-display area S2 to avoid the setting of the ground terminal 111 affecting the display effect of the display panel 100. The polarizer 120 is located in the display area S1 to adjust the display image of the display panel 100.
[0054] Among them, the conductive connecting part 130 covers the side surface of the polarizer 120 facing the grounding terminal 111, that is, the conductive connecting part 130 realizes electrical connection with the conductive layer 123 in the polarizer 120 by covering the side surface of the polarizer 120, and the polarizer 120 is located in the display area S1, and the grounding terminal 111 is located in the non-display area S2. The side surface of the polarizer 120 facing the grounding terminal 111 is the side surface of the polarizer 120 at the junction of the corresponding display area S1 and the non-display area S2 where the grounding terminal 111 is provided. Setting the conductive connecting part 130 on this side surface helps the conductive connecting part 130 to directly extend to be electrically connected to the grounding terminal 111, and will not affect the display of the display panel 100.
[0055] It should be noted that since the polarizer 120 is a stacked structure as a whole and the thickness of the polarizer 120 as a whole is relatively thin, by directly covering one of the entire side surfaces of the polarizer 120 with the conductive connecting part 130, it is helpful to reduce the difficulty and precision of making the conductive connecting part 130, and improve the overall production efficiency and production yield of the display panel 100; at the same time, since the conductive layer 123 achieves its conductive properties by adding conductive particles, if the conductive particles are unevenly dispersed, it may cause different conductive capacities in different areas of the conductive layer 123, and by directly covering one of the entire side surfaces of the polarizer 120 with the conductive connecting part 130, the impact of the uneven distribution of the conductive particles can be effectively reduced, so as to ensure the smooth discharge of the static charge generated on the surface of the display panel 100, and reduce the impact of the static charge on the overall performance of the display panel 100.
[0056] In addition, in some embodiments, the first adhesive layer 121 contains a plurality of conductive particles, that is, the first adhesive layer 121 can also be set as a conductive layer 123, and serve as a conductive path for electrostatic charge to conduct the electrostatic charge. Among them, the conductive layer 123 in the optical functional layer 122 is arranged at intervals from the first adhesive layer 121, that is, the conductive layer 123 in the optical functional layer 122 is located in the optical functional layer 122 closer to the surface of the display panel 100. Since the first adhesive layer 121 is a film layer connecting the polarizer 120 and the display substrate 110, it is the film layer farthest from the surface of the display panel 100 in the polarizer 120. By setting the conductive layer 123 in the optical functional layer 122 at a position closer to the surface of the display panel 100 and cooperating with the first adhesive layer 121, the distribution range of the conductive layer 123 in the polarizer 120 can be wider, thereby realizing the rapid conduction of electrostatic charge in different areas of the surface of the display panel 100.
[0057] It should be noted that, when the first adhesive layer 121 is also configured as a conductive layer 123, the entire polarizer 120 can be considered as a whole, and the configuration and electrical connection method of the first adhesive layer 121 and the conductive layer 123 in the optical functional film layer can refer to the relevant description of the configuration and electrical connection method of at least two conductive layers 123 in the optical functional film layer in the above embodiment, which will not be repeated here.
[0058] Secondly, an embodiment of the present application also provides a display device, which includes a display panel. The specific structure of the display panel refers to the above embodiment. Since the display device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.
[0059] See also Figure 5 , Figure 5 This is a schematic diagram of the structure of a display device provided in an embodiment of the present application. Figure 5 As shown, the display device 10 includes a display panel 100, a control circuit 200 and a housing 300. The housing 300 is connected to the display panel 100 to support and fix the display panel 100, and the control circuit 200 is disposed in the housing 300, and the control circuit 200 is electrically connected to the display panel 100 to control the display panel 100 to display a picture.
[0060] The display panel 100 can be fixed to the housing 300 to form a whole with the housing 300, and the display panel 100 and the housing 300 form a closed space for accommodating the control circuit 200. The control circuit 200 can be the main board of the display device 10, and at the same time, the control circuit 200 can also be integrated with one or more functional components such as a battery, an antenna structure, a microphone, a speaker, an earphone interface, a universal serial bus interface, a camera, a distance sensor, an ambient light sensor, and a processor, so that the display device 10 can be adapted to various application fields.
[0061] Specifically, Figure 1 As shown, the display panel 100 includes a display substrate 110, a polarizer 120 and a conductive connecting part 130. A ground terminal 111 is provided on the display substrate 110. The polarizer 120 is arranged on the display side of the display substrate 110. The polarizer 120 includes a first adhesive layer 121 and an optical function layer 122 which are arranged in sequence along a direction away from the display substrate 110. The first adhesive layer 121 is connected to the display substrate 110. The optical function layer 122 includes at least one conductive layer 123. The conductive connecting part 130 electrically connects the conductive layer 123 and the ground terminal 111.
