It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application aims at the technical problem that the width of frame glue of the existing liquid crystal display panel is reduced, so that the water vapor blocking capacity of the liquid crystal display panel is reduced, and the embodiment of the application is used for relieving the technical problem.
As shown in fig. 1, an embodiment of the present application provides a liquid crystal display panel, including:
a first substrate 11;
a second substrate 12 provided in a cassette with the first substrate 11;
a liquid crystal layer 13 disposed in a liquid crystal cell formed by the first substrate 11 and the second substrate 12 facing each other;

The embodiment of the application provides a liquid crystal display panel, through adulterating the unit that blocks water in the frame glue for the unit that blocks water reduces the moisture permeability of frame glue, avoids steam to invade to the liquid crystal display panel in from frame glue, improves liquid crystal display panel's the performance that blocks water.
Aiming at the problem that when the inorganic filler and the organic filler are arranged in the frame glue at present, the mass fraction of the inorganic filler in the frame glue is smaller than that of the organic filler in the frame glue, so that the water oxygen barrier performance of the frame glue is poor. In one embodiment, the water blocking unit includes a filler, the filler includes an inorganic filler and an organic filler, and a mass fraction of the inorganic filler in the sealant is greater than a mass fraction of the organic filler in the sealant. By enabling the mass fraction of the inorganic filler in the frame glue to be larger than that of the organic filler in the frame glue, the water oxygen blocking capability of the inorganic filler is better than that of an organic material, so that the mass fraction of the inorganic filler in the frame glue is improved, the water oxygen blocking capability of the liquid crystal display panel is improved, and meanwhile, due to the existence of the organic material, the flexibility of the frame glue is maintained, so that the liquid crystal display panel still has better bending performance when the liquid crystal display panel needs to be bent.
In one embodiment, the mass fraction of the organic filler in the sealant is in a range from one half to two thirds of the mass fraction of the inorganic filler in the sealant; in the process of setting the organic filler and the inorganic filler, in order to improve the water oxygen blocking capability of the frame sealant, the mass fraction of the inorganic filler is increased, but the mass fraction of the organic filler is increased in consideration of the flexibility of the frame sealant, so that the water oxygen blocking capability of the frame sealant and the flexibility of the frame sealant are integrated, the mass fraction range of the organic filler in the frame sealant is set to be one half to two thirds of the mass fraction of the inorganic filler in the frame sealant, the moisture permeability of the frame sealant is reduced, and the flexibility of the frame sealant is maintained.
In one embodiment, the mass fraction of the organic filler in the sealant is in a range from 2% to 4%, and the flexibility of the sealant is maintained by increasing the mass fraction of the inorganic material to improve the water and oxygen barrier capability of the sealant.
In one embodiment, the mass fraction of the inorganic filler in the sealant is in a range of 4% to 10%; in order to reduce the moisture permeability of the liquid crystal display panel, the mass fraction of the inorganic filler is increased, but the excessive mass fraction of the filler in the sealant affects other properties of the sealant, so the mass fraction of the inorganic filler is set to be in a range of 4% to 10%, and the moisture permeability of the sealant is reduced while avoiding affecting other properties of the sealant, such as the flexibility of the sealant and the toughness of the sealant.
Aiming at the fact that the contact area between different areas of the current frame glue and the outside is different, the frame glue has an area with high moisture permeability, and water vapor can invade from the area with high moisture permeability. In one embodiment, the sealant includes a first sealant and a second sealant, the first sealant is doped with a water blocking unit, and a moisture permeability of the first sealant is less than or equal to a moisture permeability of the second sealant. When the first frame glue corresponds to the area with higher moisture permeability of the frame glue and the second frame glue corresponds to the area with lower moisture permeability of the frame glue, the moisture permeability of the area corresponding to the first frame glue is reduced by reducing the moisture permeability of the first frame glue, so that the moisture permeability of the liquid crystal display panel is reduced.
In the above embodiments, the reduction of the moisture permeability of the first sealant is described in detail, but in other embodiments of the present application, the moisture permeability of the second sealant can also be reduced, so that the moisture permeability of the liquid crystal display panel is further reduced.
In one embodiment, the water blocking unit includes a first filler, the second sealant is doped with a second filler, and the moisture permeability of the first filler is less than or equal to that of the second filler. The first filler is doped in the first frame glue, and the second filler is doped in the second frame glue, so that the moisture permeability of the first filler is smaller than or equal to that of the second filler, and the moisture permeability of the first frame glue is reduced.
In the above embodiments, the first filler of the first sealant is described in detail, but in other embodiments of the present disclosure, the moisture permeability of the second sealant can be reduced, so that the moisture permeability of the first sealant and the second sealant is smaller than that of the current sealant, thereby reducing the moisture permeability of the sealant and improving the capability of the liquid crystal display panel to block water vapor.
In an embodiment, the diameter of the first filler is smaller than or equal to the diameter of the second filler, that is, when the sealant is formed by using the filler, the diameter of the first filler is reduced, and when the mass fractions of the materials in the sealant are the same, the particle spacing between the first sealant and the second sealant is smaller, so that the compactness of the sealant is improved, and the moisture permeability of the sealant is reduced.
In one embodiment, the first filler has a diameter in the range of 0.5 to 2 microns; compared with the diameter range of the filler in the current frame glue of 1-4 microns, the compactness of the first frame glue is improved, the moisture permeability of the frame glue is reduced, and the water and oxygen blocking capability of the liquid crystal display panel is improved by reducing the diameter range of the first filler, namely reducing the size of the first filler.
In one embodiment, the first filler comprises a first inorganic filler and a first organic filler, the first inorganic filler having a diameter in a range of 0.5 microns to 2 microns; compared with the size of the inorganic filler in the current frame glue, the size of the first inorganic filler is reduced, so that when the frame glue is formed by adopting the first inorganic filler and the first organic filler, the size of the first inorganic filler is smaller, the compactness of the formed frame glue is better, the moisture permeability of the frame glue is reduced, and the water and oxygen blocking capability of the liquid crystal display panel is improved.
In one embodiment, the first filler includes a first inorganic filler and a first organic filler, the first organic filler having a diameter in a range of 0.5 microns to 2 microns; compared with the size of the organic material in the current frame glue, the size of the first organic material is reduced, so that when the frame glue is formed by adopting the first inorganic filler and the first organic filler, the size of the first organic filler is smaller, the compactness of the formed frame glue is better, the moisture permeability of the frame glue is reduced, and the water and oxygen blocking capability of the liquid crystal display panel is improved.
In the above embodiments, the diameter is used to define the size of the first filler, the first inorganic filler and the second organic filler, because each material in the sealant is embodied as particles, which are generally spherical or sphere-like, but when the first filler, the first inorganic filler and the second organic filler are in other shapes, such as rectangular or cuboid-like, the length, width and height of the first filler, the first inorganic filler and the first organic filler can be defined, or the volume of the first filler, the first inorganic filler and the first organic filler can be defined, so that the compactness of the first filler, the first inorganic filler and the first organic filler is improved, and the moisture permeability of the sealant is reduced.
The hydrophilic material is adopted for the organic filler in the current frame glue, and the moisture permeability of the frame glue is higher, so that the water vapor blocking capability of the liquid crystal display panel is poorer. In one embodiment, the first filler includes a first inorganic filler and a first organic filler, the second filler includes a second inorganic filler and a second organic filler, and the first organic filler has a hydrophilicity less than a hydrophilicity of the second organic filler. The first frame glue is formed by the organic filler with lower hydrophilicity, so that the water vapor blocking capacity of the first frame glue is improved, and the water vapor blocking capacity of the liquid crystal display panel is improved.
Aiming at the frame glue which adopts acrylic monomer resin as organic filler at present, the acrylic monomer is a hydrophilic material, the moisture absorption rate is high, and the water vapor blocking capability of the frame glue is poor. In one embodiment, the first filler includes a first inorganic filler and a first organic filler, and a material of the first organic filler includes urethane acrylic resin. The first organic filler is formed by adopting the polyurethane acrylic resin which is a hydrophobic material, the moisture absorption rate of the material is low, so that the water vapor blocking capability of the frame glue is improved, the material can keep good dispersibility, and when the first organic filler and the first inorganic filler are mixed with other materials in the frame glue, the first organic filler is uniformly mixed.
In one embodiment, the material of the first inorganic filler includes at least one of silicon dioxide, silicon nitride, and silicon oxynitride. The first inorganic filler is formed by silicon dioxide, silicon nitride and silicon oxynitride, so that the water and oxygen blocking capability of the first inorganic filler can be improved.
The frame glue solves the problem that the moisture permeability of the frame glue is high due to the fact that the mass fraction of the filler in the current frame glue is low and the mass fraction of the inorganic filler is low. In one embodiment, the water blocking unit includes a filler, and a mass fraction of the filler in the sealant is in a range from 5% to 10%. The mass fraction of the filler in the frame glue is 5-10%, so that the mass fraction of the filler is improved, the mass fraction of the inorganic filler is improved, the moisture permeability of the frame glue is reduced, and the water and oxygen blocking capability of the liquid crystal display panel is improved.
In the above embodiment, the mass fraction of the filler in the sealant is increased, but in other embodiments of the present application, the mass fraction of the inorganic filler in the filler may be increased without changing the mass fraction of the filler in the sealant, so that the mass fraction of the inorganic filler in the filler is increased to be higher than that of the organic filler in the filler, thereby reducing the moisture permeability of the sealant and improving the water and oxygen blocking capability of the liquid crystal display panel.
In one embodiment, the frame glue comprises epoxy resin, acrylic resin, a photoinitiator, a thermal curing agent, a cross-linking agent and a filler, and the mass fraction of the filler ranges from 5% to 10%; the frame glue is formed by adopting the materials, and the mass fraction of the filler is controlled to be 5-10%, so that the mass fraction of the filler is improved, the mass fraction of the inorganic filler is improved, the moisture permeability of the frame glue is reduced, and the water and oxygen blocking capability of the liquid crystal display panel is improved.
