That is, the polymer wall 106 of the embodiment forms a full-surface wall between the first flexible substrate 101 and the second flexible substrate 102, so that a supporting structure that simultaneously supports the first flexible substrate 101 and the second flexible substrate 102 is formed by the polymer wall 106, and the first flexible substrate 101 and the second flexible substrate 102 can be supported by the polymer wall 106 in the deformation process of the flexible display panel 100, thereby preventing the case that the display effect of the flexible display panel 100 is affected due to a large change in the thickness of the box, ensuring the display effect of the flexible display panel 100, and improving the reliability and quality of the flexible display panel 100.
The polymer wall 106 of the embodiment can be formed by irradiating the reactive monomer disposed between the first flexible substrate 101 and the second flexible substrate 102 with ultraviolet light, and performing a corresponding polymerization reaction. In order to prevent the black matrix 105 from blocking the ultraviolet light when the ultraviolet light irradiates the reactive monomer from one side of the first flexible substrate 101, the black matrix 105 is disposed on the second flexible substrate 102 for avoiding light, so that the reaction effect between the ultraviolet light and the reactive monomer is ensured, and the quality and reliability of the polymer wall 106 are improved.

In other embodiments, the perpendicular projection of the black matrix 105 on the first flexible substrate 101 is located between the open areas 107. That is, the black matrix 105 is provided corresponding to the space between the plurality of color filter layers 104 provided at intervals.
With the above arrangement, the black matrix 105 and the color filter layer 104 having the light shielding effect can be arranged in a staggered manner, so that the black matrix 105 is prevented from affecting light passing through the color filter layer 104. Thereby ensuring the display effect of the flexible display panel 100.
In other embodiments, the perpendicular projection of the polymer wall 106 on the first flexible substrate 101 is completely coincident with the perpendicular projection of the black matrix 105 on the first flexible substrate 101. I.e. the polymer walls 106 are located within the vertical projection of the black matrix 105. Thereby preventing the polymer wall 106 from affecting the light passing through the color filter layer 104 by using the light-shielding region formed by the black matrix 105 itself. Thereby ensuring the display effect of the flexible display panel 100.
Moreover, the vertical projection of the polymer wall 106 on the first flexible substrate 101 completely coincides with the vertical projection of the black matrix 105 on the first flexible substrate 101, so that the floor area of the polymer wall 106 can be enlarged, the supporting effect of the polymer wall 106 is further improved, and the box thickness of the flexible display panel 100 is ensured.
In other embodiments, the size of the polymer wall 106 matches the size of the open area 107. That is, the black matrix 105 and the polymer wall 106 are matched with the size of the opening area 107, and referring to fig. 1, the size here may refer to the size of the cross-sectional area of the black matrix 105, the polymer wall 106 and the opening area 107, in other words, in fig. 1, the width of the polymer wall 106 is consistent with the width of the black matrix 105 and the opening area 107.

And the size of the polymer wall 106 is matched with the size of the opening area 107, so that the side surface of the polymer wall 106 is attached to the plurality of color filter layers 104, and the stability and reliability of the polymer wall 106 can be improved by utilizing the close arrangement between the color filter layers 104 and the polymer wall 106.
In addition, the size of the polymer wall 106 can be adjusted by the size of the opening area 107 between the color filter layers 104, so that the polymer wall can meet various size requirements.
In other embodiments, the flexible display panel 100 further includes a liquid crystal layer 103, the liquid crystal layer 103 is disposed between the first flexible substrate 101 and the second flexible substrate 102, liquid crystal molecules 1031 are disposed in the liquid crystal layer 103, and the liquid crystal molecules 1031 are separated by the polymer wall 106. Therefore, the polymer wall 106 can be used to prevent the liquid crystal molecules 1031 from flowing around when the flexible display panel 100 bends, which may cause the uneven distribution of the liquid crystal molecules 1031 to affect the display effect of the flexible display panel 100.
In the liquid crystal layer 103 of this embodiment, reaction monomers are further uniformly mixed, and the formation of the polymer wall 106 can be achieved after the ultraviolet light is irradiated on a part of the reaction monomers.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a flexible display panel according to a second embodiment of the present disclosure. The relative arrangement and the relative connection relationship of the first flexible substrate, the second flexible substrate, the black matrix, the color filter layer, the opening area, the polymer wall, and the liquid crystal in this embodiment are the same as those in the previous embodiment, and are not repeated herein.
The flexible display panel 200 of the present embodiment further includes a plurality of ultraviolet blocking layers 208, and the ultraviolet blocking layers 208 are disposed on the first flexible substrate 201 and correspond to the color filter layer 204.
Specifically, the vertical projections of the ultraviolet blocking layers 208 on the first flexible substrate 201 completely coincide with the vertical projections of the color filter layers 204 on the first flexible substrate 201, so that ultraviolet light irradiated onto the color filter layers 204 is completely blocked by the ultraviolet blocking layers 208, the ultraviolet light is further blocked from being irradiated onto the liquid crystal layer corresponding to the color filter layers 204, and a polymerization reaction between a reaction monomer in the liquid crystal layer corresponding to the color filter layers 204 and the ultraviolet light is avoided. And the gaps between the ultraviolet light blocking layers 208 correspond to the opening regions 207 between the color filter layers 204, so that ultraviolet light can pass through the gaps between the ultraviolet light blocking layers 208 and the opening regions 207 and irradiate onto the corresponding reactive monomers in the liquid crystal layer 203, thereby forming the polymer wall 206.
The ultraviolet light blocking layer 208 of the present embodiment may include a UV film or other transparent ultraviolet light blocking material.
In an implementation manner of the present embodiment, the ultraviolet blocking layer 208 may be disposed on a surface of a side of the first flexible substrate 201 away from the second flexible substrate 202. Therefore, the ultraviolet light barrier layer 208 can be directly attached to the surface of the first flexible substrate 201, the operation is simple, and the preparation efficiency is high.
Through the structure, the ultraviolet blocking layer is arranged corresponding to the color filter layer to block the reaction monomer corresponding to the area where the color filter layer is located, so that the formation of a polymer wall body can be guaranteed, the polymerization reaction of the reaction monomer which does not need to be subjected to polymerization reaction can be avoided, and the reliability and the stability of the flexible display panel are improved.
Referring to fig. 3, fig. 3 is a schematic view of an installation structure of another embodiment of the ultraviolet blocking layer in the embodiment of fig. 2.
The ultraviolet light blocking layer 208 of the present embodiment is disposed between the first flexible substrate 201 and the color filter layer 204. Thereby, the ultraviolet light blocking layer 208 is supported on both sides, and the mounting stability of the ultraviolet light blocking layer 208 is further improved.
Since the uv blocking layers 208 of the present embodiment are disposed between the first flexible substrate 201 and the second flexible substrate 202, the polymer wall 206 away from the second flexible substrate 202 not only passes through the opening region 207, but also passes through the gaps between the uv blocking layers 208 until contacting the first flexible substrate 201. Thereby forming a complete wall between the first flexible substrate 201 and the second flexible substrate 202, improving the sealing performance of the polymer wall 206, and further improving the blocking effect of the polymer wall 206.
Referring to fig. 4, fig. 4 is a schematic view of an installation structure of another embodiment of the ultraviolet blocking layer in the embodiment of fig. 2.
