The embodiment of the application provides a flexible display panel and a display device, which are respectively described in detail below.
Referring to fig. 1-3, an embodiment of the present application provides a flexible display panel, the display panel includes a central area and edge areas 102 located at two sides of the central area, and the flexible display panel is bent from the central area to the edge areas 102 at two sides.
The flexible display panel further includes a first flexible substrate 10, a second flexible substrate 20, a liquid crystal layer 30, and a support layer 40.
The first flexible substrate 10 is a thin film transistor array substrate (TFT Array Substrate). The second flexible substrate 20 is a color film substrate, and the second flexible substrate 20 is disposed opposite to the first flexible substrate 10. The flexible display panel is provided with a plurality of pixel units, each pixel unit is provided with a common electrode and a pixel electrode, the pixel electrodes are arranged on one surface of the first flexible substrate, which faces the liquid crystal layer, the common electrodes are arranged on one surface of the second flexible substrate, which faces the liquid crystal layer, and the pixel electrodes and the common electrodes are arranged in an mutually insulating manner. In this embodiment, the common electrode entirely covers the plurality of pixel units.
A liquid crystal layer 30 is disposed between the first and second flexible substrates 10 and 20, and the liquid crystal layer 30 includes a plurality of liquid crystal molecules and a plurality of reactive monomers (ReactiveMesogen, RM) (not shown) formed in the liquid crystal layer 30 in a doped form for assisting in stable alignment. Wherein the liquid crystal molecules include first liquid crystal molecules 31 and second liquid crystal molecules 32. The second liquid crystal molecules 32 and the second flexible substrate 20 may be disposed perpendicular to each other.
The support layer 40 is disposed between the liquid crystal layer 30 and the first flexible substrate 10, the support layer 40 is inclined from the edge region 102 to the central region 101, the first liquid crystal molecules 31 are disposed near the support layer 40, and the second liquid crystal molecules 32 are disposed near the second flexible substrate 20. As shown in fig. 2, in the initial state, the first flexible substrate 10 is disposed in a plane, in the central area 101, the surface of the supporting layer 40 is disposed in an inclined manner, the surface of the supporting layer 40 and the first flexible substrate 10 have an included angle α, and the first liquid crystal molecules 31 are disposed perpendicular to the supporting layer 40, so that the first liquid crystal molecules also have a pretilt angle α, and the second liquid crystal molecules 32 have a pretilt angle of 0 because the second liquid crystal molecules 32 are close to the two flexible substrates 20, i.e., the pretilt angles of the first liquid crystal molecules and the second liquid crystal molecules are different.
The flexible display panel provided by the embodiment of the application is characterized in that the supporting layer 40 is arranged between the liquid crystal layer 30 and the first flexible substrate 10, the supporting layer 40 is inclined from the edge area 102 to the central area 101, the first alignment layer 51 is arranged on the supporting layer 40, and the first alignment layer 51 is inclined from the edge area 102 to the central area 101. Therefore, the first alignment layer 51 is also inclined from the edge area 102 to the central area 101, so that the pretilt angle of the first liquid crystal molecules disposed on the surface of the first alignment layer 51 is different from the pretilt angle of the second liquid crystal molecules 32 close to the second flexible substrate 20, and the first liquid crystal molecules 31 and the second liquid crystal molecules 32 have different pretilt angles, so that when the second flexible substrate 20 and the first flexible substrate 10 are bent, the problem of dislocation of the pretilt angles of the liquid crystal molecules in the liquid crystal layer 30 caused by the bending of the second flexible substrate 20 and the first flexible substrate 10 can be compensated, and the brightness uniformity of the curved screen is improved, thereby improving the display effect.
In some embodiments, the support layer 40 is disposed centrally symmetrically. For example, referring to fig. 4 to 6, the supporting layer 40 may have a circular, rectangular or regular hexagonal equiaxed symmetrical shape, so that the long axes of the first liquid crystal molecules 31 are arranged in a central symmetrical manner, and the flexible display panel maintains uniformity of viewing brightness at different viewing angles.
In some embodiments, the support layer 40 is made of a transparent plastic material. Illustratively, the material of the supporting layer 40 may be patterned by using photolithography and etching processes to form a plurality of partially etched regions, so that the unetched regions of the supporting layer 40 have a sufficient thickness, thereby simplifying the process and reducing the cost.
The positive photoresist and the negative photoresist have different designs, the exposed part of the positive photoresist can be removed, and the unexposed part of the negative photoresist can be removed, so that the processing is convenient.
In some embodiments, the thickness of the support layer 40 decreases gradually from the border region 102 toward the central region 101, or the thickness of the support layer 40 increases gradually from the border region 102 toward the central region. When the electric field is applied, the central area 101 is inclined, and the electric field intensity of the surface of the central area 101 is inconsistent with the electric field intensity of the surface of the electrode, so that the electric lines of force near the central area 101 are inclined, and the first liquid crystal molecules 31 deflect around the central area 101 in different directions, thereby enlarging the display viewing angle.
In some embodiments, the thickness of the edge area 102 of the supporting layer 40 is less than 2 μm, the inclined portion of the central area 101 of the supporting layer 40 forms an angle ranging from 1 ° to 2 ° with the first flexible substrate 10, and the pretilt angle of the first liquid crystal molecule 31 is 1 ° to 2 ° more than the pretilt angle of the second liquid crystal molecule 32 with respect to the second liquid crystal molecule 32, and by controlling the thickness of the edge area 102 of the supporting layer 40 to be within a smaller range, the pretilt angle of the first liquid crystal molecule 31 is kept within a smaller range, so that the flexible display panel is in a dark state under the condition that no electric field is applied, which is favorable for avoiding dark state light leakage, and the brightness is lower in the dark state, which is favorable for improving the contrast ratio.
In some embodiments, the flexible display panel further includes a second alignment film 52.
The initial state of the first liquid crystal molecules 31 on the first alignment layer 51 may be perpendicular to the surface of the first alignment layer 51, so that the first liquid crystal molecules 31 are inclined from the edge regions 102 on both sides to the central regions 101, respectively, which is advantageous for improving the visual performance of the flexible display panel.
The second alignment film 52 is disposed on a surface of the second flexible substrate 20 near the liquid crystal layer 30. Specifically, the first alignment layer 51 and the second alignment film 52 are respectively located on the first flexible substrate 10 and the second flexible substrate 20, the first alignment layer 51 and the second alignment film 52 are disposed opposite to each other, and the liquid crystal layer 30 is located between the first alignment layer 51 and the second alignment film 52. The first alignment layer 51 and the second alignment film 52 may be a photoalignment film or a rubbing alignment film. Illustratively, in the embodiment of the present application, the first alignment layer 51 and the second alignment film 52 may be made of Polyimide (PI).
In some embodiments, the support layer 40 is disposed on the light incident side of the flexible display panel, and since the support layer 40 is disposed close to the first flexible substrate 10, the first liquid crystal molecules 31 are disposed on the support layer 40, the second liquid crystal molecules 32 are disposed far away from the light incident side, and the second alignment film 52 of the second liquid crystal molecules 32 is disposed on the second flexible substrate 20, the pretilt angle of the first liquid crystal molecules 31 is greater than the pretilt angle of the second liquid crystal molecules 32, that is, the first liquid crystal molecules 31 are inclined more than the second liquid crystal molecules 32, and by making the pretilt angle of the first liquid crystal molecules 31 close to the light incident side of the flexible display panel greater than the pretilt angle of the first liquid crystal molecules 31 far away from the light incident side, so as to compensate for the dislocation of the pretilt angle between the first liquid crystal molecules 31 and the second liquid crystal molecules 32 caused by bending of the curved screen, thereby improving the brightness uniformity of the curved screen.
