The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.
The present application is described in detail below with reference to the attached drawings and alternative embodiments.
As shown in fig. 1, as a first embodiment of the present application, a display panel 100 is disclosed, the display panel 100 includes a first substrate 110 and a second substrate 120 disposed opposite to each other, a liquid crystal layer 130 and a sealant layer 140 are disposed between the first substrate 110 and the second substrate 120, the sealant layer 140 includes a sealant portion 141 and a liquid crystal penetrating portion 142, the sealant portion 141 is formed of a sealant material, and the liquid crystal penetrating 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 penetration threshold of the liquid crystal penetration portion 142, the liquid crystal penetrates out of the frame glue through the liquid crystal penetration portion 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 frame glue through the liquid crystal permeation portion 142.
Since the normal frame glue material cannot permeate out the liquid crystal, if the quantity of the liquid crystal is too large after the manufacture process, the liquid crystal can fall down and accumulate to the lower side of the display panel 100 along the gravity direction under the influence of gravity in the later use process, so that the thickness of the box at the lower side of the display panel 100 is increased, the liquid crystal box is deformed, and the conditions of gravity mura, yellowing at the lower side of the display panel 100 and the like occur; in the embodiment, the partial area of the frame glue is replaced by a special hole structure 143 material, and redundant liquid crystal in the liquid crystal box can be discharged by utilizing 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 gap height between the substrates is increased, thereby preventing the generation of gravity MURA; the design expands the range of liquid crystal dosage in the process, can enable the liquid crystal quantity in the liquid crystal screen to be in a very 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 the penetration threshold, the liquid crystal penetrates the frame glue through the liquid crystal penetration portion 142, but the quantity of the liquid crystal is normal, and there is no excessive condition, so the pressure between the liquid crystals is very small and is mainly affected by gravity, but the light cannot penetrate due to gravity, and considering that the service time of the display surface is long, the liquid crystal quantity in the partial region is different, so the penetration threshold of the liquid crystal penetration portion 142 can be adjusted according to the actual condition for different regions.
As shown in fig. 2, as a further refinement of the first embodiment, a plurality of liquid crystal penetrating portions 142 and a plurality of frame glue portions 141 are provided at intervals, and a length of the liquid crystal penetrating portion 142 is smaller than a length of the frame glue portion 141. Considering that the frame glue is important for fixing the thickness of the case, the length of the frame glue portion 141 is greater than that of the liquid crystal penetrating portion 142, but the length of the liquid crystal penetrating portion 142 should not be too long, and only the smaller the opening is, the more easily the liquid crystal inside the liquid crystal penetrating portion 142 is penetrated after being extruded.
The liquid crystal penetrating portions 142 are circumferentially arranged at the edge of the display panel 100, and the distances between any two liquid crystal penetrating portions 142 are the same, or may be different, and may be selected according to actual situations; for example, in the case of performing the simulation in a box, if the excessive liquid crystal amount is uniformly distributed in each area, the corresponding liquid crystal penetration portions 142 may be uniformly arranged at equal intervals, and it is found that if the liquid crystal amount near the four sides of the display panel 100 is unevenly distributed, the liquid crystal penetration portions 142 may be arranged according to a specific distribution situation, for example, the liquid crystal amount in the lower frame 190 of the display panel 100 may be increased, and more liquid crystal penetration portions 142 may be arranged corresponding to the lower frame 190 instead of the frame glue.
Generally, at least four liquid crystal penetrating portions 142 are provided, and four liquid crystal penetrating portions 142 are provided at four opposite corners of the frame glue. The outer side corresponding to each liquid crystal penetrating portion 142 is provided with UV glue, and after the liquid crystal penetrates the frame glue through the liquid crystal penetrating portions 142, the UV glue or other solid glue is provided to block the flowing liquid crystal from entering other areas.
In addition, the frame glue is far away from the layer of the liquid crystal layer 130, and the liquid crystal permeation portion 142 is disposed corresponding to the layer of the tambour glue, so that the permeated liquid crystal can be blocked from flowing into other places by utilizing the tambour glue, and no other solid glue is required to be additionally disposed to block the permeated liquid crystal layer 130.
As shown in fig. 3, as a further refinement and perfection of the second embodiment, the display panel 100 includes an upper frame 180 and a lower frame 190, the lower frame 190 is disposed below the upper frame 180 along the gravity direction, the liquid crystal permeable portion 142 of the upper frame 180 is a first liquid crystal permeable portion 1421, the liquid crystal permeable portion 142 of the lower frame 190 is a second liquid crystal permeable portion 1422, the permeability threshold of the second liquid crystal permeable portion 1422 located in the lower frame 190 is greater than the permeability threshold of the first liquid crystal permeable portion 1421 located in the upper frame 180, and the permeability threshold is set according to the diameter of the hole structure 143.
In consideration of the influence of gravity or the falling of a part of liquid crystal to the lower side of the display panel 100, the liquid crystal panel is caused to fall down, but the amount of the falling liquid crystal is very small, and the display of the liquid crystal is not affected, on the contrary, since the situation that the lower liquid crystal is much is considered, other places may be improved, such as brightness may be adjusted, driving voltage may be changed, etc., that is, the set value of the amount of the liquid crystal in the part is larger than the amount of the liquid crystal in other areas, 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, so that the liquid crystal of the lower frame 190 is prevented from penetrating out, the original balance state is broken, and the display effect is affected.
In addition to the above, the liquid crystal dropping amount is increased after the panel is used for a long time, and the amount of the liquid crystal on the upper side of the display panel 100 is obviously reduced, which has a significant effect on the display effect, so in this embodiment, an annular backflow channel 200 is arranged on the side of the frame glue away from the liquid crystal, as shown in fig. 4, the liquid crystal permeation portion 142 is communicated with the backflow channel 200, the backflow channel is also in a vacuum arrangement, the material for preparing the backflow channel 200 does not pollute the liquid crystal, the liquid crystal permeated by the liquid crystal permeation portion 142 on the lower side of the display panel 100 is returned into the liquid crystal box again through the backflow channel 200, and the situation that the difference between the amount of the liquid crystal on the upper end and the lower end in the liquid crystal box is too large is compensated.
As shown in fig. 5, as a fourth embodiment of the present application, a plurality of first support columns 150 are disposed between the first substrate 110 and the second substrate 120, the first support columns 150 are disposed on the first substrate 110 and extend toward the second substrate 120, a first preset distance is disposed between adjacent first support columns 150, a plurality of second support columns 160 are disposed on the second substrate 120, the second support columns 160 extend toward the first substrate 110 and are abutted to the first support columns 150, a magnetic material 170 is disposed at an end of the first support columns 150 away from the first substrate 110, a magnetic material 170 is disposed at an end of the second support columns 160 away from the second substrate 120, and the first support columns 150 and the second support columns 160 are fixed by magnetic force.
Because liquid crystal quantity is too much, after the thermal expansion, the liquid crystal box thickness can increase, can make external pressure and stop when increasing, so can lead to liquid crystal panel to produce deformation, influence the display effect, produce the in-process of deformation, support column on the base plate also can be influenced, the circumstances that can appear the skew or drop takes place, in case produce the removal, can influence the flow of liquid crystal, lead to the equilibrium of liquid crystal to be broken, cause the liquid crystal to drop, simultaneously can also lead to the dislocation of pixel, produce light leak and gravity mura phenomenon, the top of the butt of the support column that this application set up on two base plates adopts magnetic material 170 to make, the attractive force between two support columns can reduce the outside expansive power of liquid crystal panel, and two support columns are in the same place because of magnetic force fixed connection, form a whole, lateral shifting is less prone to produce.
It should be noted that, the inventive concept of the present application may form a very large number of embodiments, but the application documents have limited space and cannot be listed one by one, so that on the premise of no conflict, the above-described embodiments or technical features may be arbitrarily combined to form new embodiments, and after the embodiments or technical features are combined, the original technical effects will be enhanced.
The foregoing is a further detailed description of the present application in connection with specific alternative embodiments, and it is not intended that the practice of the present application be limited to such descriptions. It should be understood that those skilled in the art to which the present application pertains may make several simple deductions or substitutions without departing from the spirit of the present application, and all such deductions or substitutions should be considered to be within the scope of the present application.
