The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
The present application is described in detail below with reference to the figures and alternative embodiments.
As shown in fig. 1, as a first embodiment of the present application, a display panel 100 is disclosed, where the display panel 100 includes a first substrate 110 and a second substrate 120 that are arranged in a box-to-box manner, a liquid crystal layer 130 and a frame adhesive layer 140 are disposed between the first substrate 110 and the second substrate 120, the frame adhesive layer 140 includes a frame adhesive portion 141 and a liquid crystal permeable portion 142, the frame adhesive portion 141 is formed by a frame adhesive material, and the liquid crystal permeable portion 142 is provided with a hole structure 143; when the pressure of the liquid crystal in the liquid crystal layer 130 to the hole structure 143 is greater than the permeation threshold of the liquid crystal permeation part 142, the liquid crystal permeates out of the sealant through the liquid crystal permeation part 142; if the pressure of the hole structure 143 is less than or equal to the permeation threshold of the liquid crystal permeation portion 142, the liquid crystal cannot permeate the sealant through the liquid crystal permeation portion 142.
Because the normal frame glue material cannot permeate out the liquid crystal, if the amount of the liquid crystal is too much after the manufacturing process, the liquid crystal can fall down along the gravity direction and accumulate to the lower side of the display panel 100 in the later use process under the influence of gravity, so that the box thickness of the lower side of the display panel 100 is increased, the liquid crystal box is deformed, and then the gravity mura occurs, the lower side of the display panel 100 is yellowed, and the like; in the embodiment, the special hole structure 143 is selected for replacing the sealant in a partial area of the sealant, and the redundant liquid crystal in the liquid crystal box can be discharged by using the liquid permeation principle, so that the liquid crystal in the liquid crystal box can not cause the deformation of the liquid crystal box at the lower side under the action of gravity, and the height of the gap between the substrates is increased, thereby preventing the generation of gravity MURA; the design enlarges the range of the liquid crystal consumption in the process, can ensure that the liquid crystal quantity in the liquid crystal screen is in a proper state, and prevents various problems caused by excessive liquid crystal quantity.
The aperture of the hole structure 143 is 1-10um, the hole structure 143 is made of silicon carbide, the sum of the pressure generated by excessive liquid crystal and the gravity applied to the liquid crystal is greater than a permeation threshold, the liquid crystal permeates to the outside of the sealant through the liquid crystal permeation part 142, but the amount of the liquid crystal is normal, and excessive conditions do not exist, so the pressure between general liquid crystals is very small, the liquid crystal is mainly affected by the gravity, but the light cannot permeate out due to the gravity, and considering that the service time of the display surface is long, the amount of the liquid crystal in a part of regions may be different, so that the permeation threshold of the liquid crystal permeation part 142 can be adjusted according to actual conditions in different regions.
As shown in fig. 2, as a second embodiment of the present application, the first embodiment is further refined, a plurality of liquid crystal penetration portions 142 and a plurality of frame glue portions 141 are provided, the plurality of liquid crystal penetration portions 142 and the plurality of frame glue portions 141 are provided at intervals, and the length of the liquid crystal penetration portion 142 is smaller than the length of the frame glue portion 141. Considering that the sealant is important for fixing the cell thickness, the sealant 141 should have a length longer than that of the liquid crystal penetrating part 142, and the liquid crystal penetrating part 142 should not have a too long length, and only the smaller the opening, the more easily the liquid crystal inside can penetrate from the liquid crystal penetrating part 142 after being squeezed.
The liquid crystal permeating parts 142 are arranged around the edge of the display panel 100, and the distances between any two liquid crystal permeating parts 142 are the same or different, and can be selected according to actual conditions; for example, in the case of performing a cell-forming simulation, if the number of redundant liquid crystals is uniformly distributed in each region, the corresponding liquid crystal penetration portions 142 may be uniformly arranged at equal intervals, and it is found that if the number of liquid crystals near the four sides of the display panel 100 is not uniformly distributed, the liquid crystal penetration portions 142 may be arranged according to a specific distribution condition, for example, if the number of liquid crystals is in the lower frame 190 of the display panel 100, more liquid crystal penetration portions 142 may be arranged corresponding to the lower frame 190 instead of the sealant.
Generally, there are at least four liquid crystal penetrating parts 142, and the four liquid crystal penetrating parts 142 are disposed at four diagonal positions of the sealant. The outer side corresponding to each liquid crystal penetration portion 142 is provided with a UV glue, and after the liquid crystal penetrates out of the frame glue through the liquid crystal penetration portion 142, the flowing-out liquid crystal is prevented from entering other areas by the UV glue or other solid glue.
In addition, the layer of the sealant far away from the liquid crystal layer 130 is provided with the taffy glue, and the liquid crystal penetration part 142 is arranged corresponding to the taffy glue, so that the taffy glue can be used for preventing the penetrated liquid crystal from flowing into other places, and other solid glue is not required to be additionally arranged for preventing the penetrated liquid crystal layer 130.
As shown in fig. 3, as a third embodiment of the present application, which is a further refinement and improvement of the second embodiment, the display panel 100 includes an upper frame 180 and a lower frame 190, in a gravity direction, the lower frame 190 is disposed below the upper frame 180, the liquid crystal penetration portion 142 of the upper frame 180 is a first liquid crystal penetration portion 1421, the liquid crystal penetration portion 142 of the lower frame 190 is a second liquid crystal penetration portion 1422, a penetration threshold of the second liquid crystal penetration portion 1422 located in the lower frame 190 is greater than a penetration threshold of the first liquid crystal penetration portion 1421 located in the upper frame 180, and the penetration threshold is set according to a diameter size of the hole structure 143.
Considering that the liquid crystal falls to the lower side of the display panel 100 due to the influence of gravity, so as to form the lower side of the liquid crystal panel, but the amount of the liquid crystal falling to the lower side is very small, and the display of the liquid crystal is not affected, on the contrary, since the condition that the amount of the liquid crystal in the lower part is large is considered before, the other places may be improved, such as the brightness may be adjusted, the driving voltage may be changed, and the like, that is, the amount of the liquid crystal in the part is set to be larger than the amount of the liquid crystal in other areas, so that the penetration threshold of the liquid crystal penetration part 142 of the lower frame 190 is set to be larger than the penetration threshold of the liquid crystal penetration part 142 of the upper frame 180, and the liquid crystal of the lower frame 190 is prevented from penetrating out, and the original balance state is broken, and the display effect is affected on the contrary.
In addition to the above situation, after the panel is used for a long time, the dropping amount of the liquid crystal is more and more than the previously set value, and the amount of the liquid crystal on the upper side of the display panel 100 is obviously reduced, which has a great influence on the display effect, in view of this, in this embodiment, an annular backflow channel 200 is disposed on one side of the sealant away from the liquid crystal, as shown in fig. 4, the liquid crystal penetration portion 142 is communicated with the backflow channel 200, the backflow channel is also vacuum-disposed, and the material for preparing the backflow channel 200 does not pollute the liquid crystal, and the liquid crystal penetrated from the lower side of the display panel 100 by the liquid crystal penetration portion 142 returns to the inside of the liquid crystal box through the backflow channel 200 again, so as to compensate for the situation that the difference between the amounts of the liquid crystal on the upper and lower ends in the liquid crystal box is too large.
As shown in fig. 5, as a fourth embodiment of the present application, a plurality of first supporting columns 150 are disposed between the first substrate 110 and the second substrate 120, the first supporting columns 150 are disposed on the first substrate 110 and extend toward the second substrate 120, a first preset distance is disposed between the adjacent first supporting columns 150, a plurality of second supporting columns 160 are disposed on the second substrate 120, the second supporting columns 160 face the first substrate 110 and extend toward the first substrate 150, and abut against the first supporting columns 150, a magnetic material 170 is disposed at an end of the first supporting columns 150 far from the first substrate 110, a magnetic material 170 is disposed at an end of the second supporting columns 160 far from the second substrate 120, and the first supporting columns 150 and the second supporting columns 160 are fixed by magnetic force.
Because the liquid crystal is too much, after the thermal expansion, the liquid crystal box thickness can be increased, the external pressure can be caused to block when the liquid crystal is increased, so that the liquid crystal panel can be deformed, the display effect is influenced, the deformation process is generated, the supporting columns on the substrate can also be influenced, the deviation or falling can occur, once the liquid crystal panel is moved, the liquid crystal panel can be influenced to flow, the balance of the liquid crystal is broken, the liquid crystal is fallen, the pixel dislocation can be caused, the light leakage and gravity mura phenomena are generated, the top ends of the butt joints of the supporting columns arranged on the two substrates are made of the magnetic materials 170, the two supporting columns are mutually attracted, the outward expansion force of the liquid crystal panel can be reduced through the attraction of the two supporting columns, the two supporting columns are fixedly connected together due to the magnetic force, a whole is formed, and the transverse movement is not easy to generate.
It should be noted that the inventive concept of the present application can form a great variety of embodiments, but the application documents are limited in space and cannot be listed one by one, so that, on the premise of no conflict, any combination between the above-described embodiments or technical features can form a new embodiment, and after each embodiment or technical feature is combined, the original technical effect will be enhanced.
The foregoing is a more detailed description of the present application in connection with specific alternative embodiments, and the specific implementations of the present application are not to be considered limited to these descriptions. For those skilled in the art to which the present application pertains, several simple deductions or substitutions may be made without departing from the concept of the present application, and all should be considered as belonging to the protection scope of the present application.
