Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the 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 invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a flexible display panel according to a first embodiment of the present application. In the present embodiment, the flexible display panel 10 includes: an upper substrate 11, a lower substrate 12, and a liquid crystal layer 13 disposed between the upper substrate 11 and the lower substrate 12.
Wherein the upper substrate 11 may be a CF substrate for color display in the flexible display panel 10, and the raw material thereof may be a glass substrate; the lower substrate 12 may be specifically a TFT substrate, and the TFT functions to transmit and control an electrical signal in the display panel, i.e., to determine the magnitude of a voltage applied to liquid crystals in the flexible display panel 10 therethrough; the liquid crystal layer 13 can be understood as a nematic liquid crystal layer 13, so that the transmittance of light can be controlled under different voltage driving, thereby achieving the purpose of displaying images.
Specifically, the liquid crystal layer 13 further includes a transparent polymer skeleton 131 and a plurality of liquid crystal molecules 132, and the transparent polymer skeleton 131 can correspondingly define a plurality of liquid crystal accommodation regions, so that the plurality of liquid crystal molecules 132 are respectively and correspondingly disposed in the plurality of liquid crystal accommodation regions, that is, each of the plurality of liquid crystal accommodation regions accommodates a portion of the liquid crystal molecules 132, and the plurality of liquid crystal accommodation regions can respectively limit the movement of the portion of the liquid crystal molecules 132 in each of the plurality of liquid crystal accommodation regions.
It can be understood that, when the flexible display panel 10 is forced to bend, each liquid crystal accommodation region therein can limit the liquid crystal molecules 132 in the accommodation space from moving to the outside of the accommodation space as much as possible, further, the thickness of the liquid crystal layer 13 in the bending region of the flexible display panel 10 can be kept as consistent as possible with that of other non-bending regions, that is, the liquid crystal molecules 132 in the bending region are limited by the liquid crystal accommodation regions correspondingly formed by the transparent polymer skeletons 131, without moving to both sides of the stress point, so as to maintain the uniformity of the distribution of the plurality of liquid crystal molecules 132 between the upper substrate 11 and the lower substrate 12 as much as possible, and reduce the thickness variation of the liquid crystal layer 13 when the flexible display panel 10 is bent, so that the loss of light efficiency caused by the reduction of the thickness of the liquid crystal layer 13 in the bend region can be effectively compensated, so as to effectively ensure the uniformity of display and better display effect when the flexible display panel 10 is bent.
In an embodiment, the transparent polymer skeleton 131 is a rigid material, that is, a material with a small or negligible deformation under an external force, so that when the flexible display panel 10 is bent, the transparent polymer skeleton 131 can still maintain the stability of the liquid crystal accommodation areas correspondingly formed, so as to effectively limit the movement of the liquid crystal molecules 132, and the liquid crystal molecules 132 do not move to two sides of the stressed point, so as to maintain the distribution uniformity of the liquid crystal molecules 132 as much as possible, thereby effectively ensuring the display uniformity and better display effect when the flexible display panel 10 is bent.
Further, as shown in fig. 2, fig. 2 is a schematic structural diagram of the flexible display panel in fig. 1 when the flexible display panel is bent, the transparent polymer skeleton 131 is specifically a three-dimensional cage-shaped grid structure, and each grid (not shown) in the transparent polymer skeleton 131 corresponds to a liquid crystal accommodation region, that is, each grid can accommodate a part of the liquid crystal molecules 132, so as to limit the movement of the accommodated part of the liquid crystal molecules 132.
It should be noted that the three-dimensional cage-shaped grid structure has a higher degree of branching, extends not only in the horizontal direction, but also in the vertical direction, and can better block the flow of liquid crystal molecules when the display panel is bent.
It can be understood that, when the liquid crystal layer 13 is composed of the rigid transparent polymer skeleton 131, the transparent polymer skeleton and the liquid crystal molecules 132, the liquid crystal molecules 132 can be filled in each liquid crystal accommodation region, that is, each grid skeleton, so that when the flexible display panel 10 is bent, the transparent polymer skeleton 131 can resist an external force with a certain strength, and prevent the distance between the upper and lower sides of the liquid crystal layer 13 from being greatly reduced, so as to keep the thickness of the liquid crystal box stable, and ensure that the liquid crystal molecules at the bent position are not extruded and flow to both sides in a large amount, thereby maintaining the display stability of the flexible display panel 10; compared with the existing structure that a support column and the like are filled in the liquid crystal box, the rigid organic framework, namely the whole liquid crystal layer 13 doped with the rigid transparent polymer framework 131, has larger stress area because the connecting structure between the frameworks can disperse the force of the bending point, and is more beneficial to keeping the thickness of the liquid crystal box stable; the skeleton structure, i.e. the characteristics of the rigid material, can prevent a large amount of liquid crystal molecules 132 at the bent position from flowing to two sides to a certain extent, so as to maintain the uniformity of the distribution of the liquid crystal molecules 132; in addition, the cross-linked gap-rigid skeleton structure, i.e. the transparent polymer skeleton 131 in a grid shape, is also beneficial to improving the impact toughness of the flexible display panel 10, and has a certain shock absorption effect.
Optionally, the transparent polymer skeleton 131 may be any one of materials that can be reasonably manufactured by monomer structural design and functionalization under the control of a crosslinking condition, such as polymethyl methacrylate, polyimide, a polyester polymer material, and a transparent resin, and the like, and this is not limited in this application.
It is understood that the transparent polymer frameworks 131 made of different materials usually have different lattice structures, that is, the corresponding lattice structures may be irregular, and each two lattices have different shapes, or may be relatively regular, that is, the shapes of each two lattices are approximately the same, and are specifically determined by the material of the transparent polymer framework 131, which is not limited herein.
In an embodiment, the flexible display panel 10 further includes a support pillar (not shown), and the support pillar is disposed between the upper substrate 11 and the lower substrate 12 and disposed on the same layer as the liquid crystal layer 13, so as to provide a certain support effect for the spacing arrangement of the upper substrate 11 and the lower substrate 12. In other embodiments, the transparent polymer skeleton 131 is made of a rigid material, and can provide a certain supporting strength, and the liquid crystal layer 13 doped with the transparent polymer skeleton 131 provides a certain supporting function without additionally providing a supporting column in the flexible display panel 10, which is not limited in this application.
Optionally, the support column is in any reasonable shape such as a partial cone, a trapezoid, a cylinder, or a square, which is not limited in this application.
Further, in an embodiment, the flexible display panel 10 further includes a plurality of black matrixes (not shown) disposed between the upper substrate 11 and the lower substrate 12 and spaced apart from each other and disposed in the same layer as the plurality of support pillars.
It is understood that the upper substrate 11 of the flexible display panel 10 may also be correspondingly formed with a transparent electrode layer (not shown), i.e. an ITO (indium tin oxide) layer, wherein the indium tin oxide is a mixture of a transparent brown film or a yellow-off-gray block composed of 90% In2O3(indium oxide) and 10% SnO2(silicon dioxide) is mixed and mainly used for manufacturing liquid crystal displays, flat panel displays, plasma displays, touch screens, electronic paper, organic light emitting diodes, solar cells, antistatic coatings, EMI (Electromagnetic Interference) shielding transparent conductive coatings, various optical coatings and the like.
And a common electrode layer (not shown) may be correspondingly formed on the lower substrate 12 in the flexible display panel 10 to enable a voltage to be applied to the liquid crystal layer 13 in the flexible display panel 10 through the common electrode layer.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a flexible display panel according to a second embodiment of the present application. The difference between this embodiment and the first embodiment of the flexible display panel provided in this application is that a plurality of micro holes 2311 are formed inside the transparent polymer skeleton 231 in the flexible display panel 20, and each micro hole 2311 corresponds to a liquid crystal accommodation region.
It can be understood that the liquid crystal molecules 232 are specifically respectively accommodated in each of the micro holes 2311 inside the transparent polymer skeleton 231, so as to ensure the stability of the thickness of the corresponding liquid crystal cell when the flexible display panel 20 is stressed to bend, and the liquid crystal molecules 232 in the accommodating space can be limited to move out of the accommodating space through each of the micro holes 2311, that is, the liquid crystal molecules 232 in each of the micro holes 2311 cannot break through the inner wall of the micro hole 2311 to move to other areas, so that the thickness of the liquid crystal layer 23 in the bending area of the flexible display panel 20 can be as consistent as possible with that of other non-bending areas, that is, the liquid crystal molecules 232 in the bending area are limited by the liquid crystal accommodating areas correspondingly formed by the transparent polymer skeleton 231, and cannot move to both sides of the stressed point, so as to further ensure the uniformity of the distribution of the liquid crystal molecules 232 by reducing the flow of the liquid crystal molecules, and the thickness change of the liquid crystal layer 23 when the flexible display panel 20 is bent is reduced, so that the light effect loss caused by the thickness reduction of the liquid crystal layer 23 in the bent area can be effectively compensated, and the display uniformity and the better display effect of the flexible display panel 20 when the flexible display panel is bent are effectively ensured.
In an embodiment, as shown in fig. 4, fig. 4 is a top view of a liquid crystal layer in the flexible display panel of fig. 3, and a plurality of micro-holes 2311 are specifically formed between the upper substrate 21 and the lower substrate 21 and inside a layer of transparent polymer skeleton 231, spaced apart from each other, and correspondingly arranged in an array.
In a specific embodiment, the liquid crystal layer 23 is specifically prepared by uniformly mixing the precursor of the transparent polymer skeleton 231 and the polystyrene micron-sized spheres, performing spin coating deposition to obtain a single-layer arrangement structure, arranging the micron-sized spheres in an array in the organic matrix corresponding to the transparent polymer skeleton 231, performing light curing on the organic matrix, extracting with toluene to remove the micron-sized spheres therein to obtain orderly-arranged micro-holes 2311, and filling the liquid crystal molecules 232 into each micro-hole 2311. As can be seen from this, the above-described method can realize multi-cell control of the liquid crystal layer 23.
It should be noted that the micron-sized sphere refers to a sphere with an external dimension of several micrometers to several hundred micrometers, and the specific dimension is determined by the actual size requirement of the micro-holes 2311 to be formed in the transparent polymer skeleton 231, which is not limited in the present application.
In another embodiment, the liquid crystal layer 23 may be further prepared by uniformly mixing the precursor of the transparent polymer skeleton 231 with SiO2 (silicon dioxide) micron-sized spheres, performing spin coating deposition to obtain a single-layer arrangement structure, arranging the micron-sized spheres in an array in the organic matrix corresponding to the transparent polymer skeleton 231, removing the micron-sized spheres by HF (hydrogen fluoride) etching after photocuring the organic matrix to obtain the orderly-arranged micro-hole 2311 structure, and filling the liquid crystal molecules 232 into each of the micro-holes 2311. As can be seen from this, the above-described configuration also enables multi-cell control of the liquid crystal layer 23.
According to the scheme, the micropores 2311 with different sizes are obtained by controlling the particle size of the micron-sized spheres, so that the filling amount of the liquid crystal molecules 232 can be regulated and controlled.
It is understood that in the present embodiment, the upper substrate 21, the lower substrate 22, and the liquid crystal molecules 232 are respectively the same as the upper substrate 11, the lower substrate 12, and the liquid crystal molecules 132, and please refer to fig. 1 and fig. 2 and related text, which are not repeated herein.

s31: an upper substrate is provided.
It is understood that the upper substrate may be a CF substrate in particular to be used for color display in a display panel, and the raw material thereof may be a glass substrate.

It can be understood that the transparent polymer skeleton provided herein may be a rigid transparent polymer skeleton in a grid shape, so that when the transparent polymer skeleton and the plurality of liquid crystal molecules are uniformly mixed, the plurality of liquid crystal molecules can be respectively and correspondingly accommodated in the plurality of liquid crystal accommodating areas correspondingly defined by the transparent polymer skeleton, that is, in each grid therein, so as to serve as a liquid crystal layer material.
Optionally, the transparent polymer skeleton may be any one of materials that can be reasonably manufactured through monomer structure design and functionalization under the control of a crosslinking condition, such as polymethyl methacrylate, polyimide, a polyester polymer material, and a transparent resin, and the like, and this is not limited in this application.
In other embodiments, the transparent polymer skeleton may be made of a material having a plurality of micro holes formed therein at intervals, and each of the micro holes corresponds to a liquid crystal accommodation region, so that when the transparent polymer skeleton and the plurality of liquid crystal molecules are uniformly mixed, the plurality of liquid crystal molecules can respectively enter into each of the micro holes of the transparent polymer skeleton to serve as a liquid crystal layer material.
S34: a liquid crystal layer is formed on the upper substrate by a liquid crystal layer material.
