The pixels of these different colors are arranged in a preset order, for example, in the order of the blue pixel 201, the red pixel 202, and the green pixel 203. The flexible panel emits light compositely by the blue pixel 201, the red pixel 202, and the green pixel 203, thereby displaying different colors.
An encapsulation layer 3 for preventing moisture from penetrating into the light emitting layer 2, the encapsulation layer 3 including an organic layer 30, a first inorganic layer 31, and a second inorganic layer 32. Wherein the organic layer 30 is disposed between the first and second inorganic layers 31 and 32. It is understood that the inorganic layer provided in the encapsulation layer 3 may further block moisture from penetrating into the light emitting layer 2 to further improve the reliability of the flexible display panel.

For example, the encapsulation layer 3 may include one inorganic layer, two inorganic layers, or four inorganic layers, which is not limited in the embodiment of the present application.
The materials used for the first inorganic layer 31 and the second inorganic layer 32 may be the same or different. For example, the materials used for the first inorganic layer 31 and the second inorganic layer 32 may be graphene materials, and the graphene materials themselves have the characteristics of high flexibility, high light transmittance, excellent water-oxygen barrier capability, and the like, so that the encapsulation effect of the encapsulation layer 3 can be further improved by setting the materials used for the first inorganic layer 31 to be graphene materials. As another example, the materials used for the first and second inorganic layers 31 and 32 may include at least one of aluminum nitride, aluminum oxide, silicon nitride, silicon carbide, yttrium oxide, or the like, to which the embodiment of the present application is not limited.
In an embodiment of the present application, as shown in fig. 1, the organic layer 30 includes a plurality of first organic regions 301, a plurality of second organic regions 302, and a plurality of flexible barriers 303. Wherein, according to the blue pixel 201, the red pixel 202 and the green pixel 203 which are sequentially arranged, a part of the flexible barrier 303 is positioned between the blue pixel 201 and the red pixel 202, and a part of the flexible barrier 303 is positioned between the blue pixel 201 and the green pixel 203.
It should be noted that, in order to make the flexible display panel in the bending state, the first organic region 301 and the second organic region 302 may deform to different degrees, and press the flexible barrier 303 to bend toward the non-blue pixel, that is, the flexible barrier 303 bends toward the green pixel 203 or the red pixel 202. In the embodiment of the present application, the first organic region 301 and the second organic region 302 may be disposed on both sides of each flexible barrier 303, respectively, and the elastic modulus of the material used for the first organic region 301 is greater than that of the material used for the second organic region 302, so as to ensure that the flexible barrier 303 may be bent toward the non-blue pixel when the flexible display panel is in a bent state.

Fig. 3 is a schematic cross-sectional structure of a flexible display panel configured to be folded in, as shown in fig. 3, the flexible display panel being configured to be folded in, a first organic region 301 being disposed above a blue pixel 201, and a second organic region 302 being disposed above a non-blue pixel. Specifically, as shown in fig. 3, the second organic region 302 needs to be disposed above the red pixel 202 and the green pixel 203.
In the embodiment of the present application, as can be seen from fig. 2 and 3, the flexible baffle 303 changes from the vertical state of fig. 1 to the dyke state of bending toward the non-blue pixel after being pressed. Therefore, it is possible to further block moisture from penetrating into the light emitting layer 2, thereby enhancing the encapsulation effect of the encapsulation layer 3 and improving the reliability of the flexible display panel.
In one embodiment of the present application, as shown in fig. 1, 2 and 3, the flexible barrier 303 includes a light shielding plate 3031, and the light shielding plate 3031 can shield the light of the red pixel 202 or the green pixel 203 after bending. In this embodiment, at least one of graphene, carbon nanotubes, and carbon black may be used as the material of the light shielding plate 3031, for example, the material of the light shielding plate 3031 includes graphene or a combination of graphene and carbon nanotubes, which is not limited in the embodiment of the present application.
In another embodiment of the present application, in order to make the bent flexible baffle 303 capable of shielding the light of the non-blue pixel, the light of the blue pixel 201 is increased, so that the yellow phenomenon in the bending area of the flexible display panel is more effectively reduced. As shown in fig. 4, the flexible barrier 303 may further include a reflective plate 3032, and the reflective plate 3032 is capable of reflecting light of the blue pixel 201 after being bent. In this embodiment, at least one of silver, copper, aluminum, iron, and titanium may be used as the material of the reflective plate 3032, for example, the material of the reflective plate 3032 includes silver or a combination of silver and copper, which is not limited in the embodiment of the present application.
As shown in fig. 4, the light reflecting plate 3032 and the light shielding plate 3031 may be disposed substantially in parallel, specifically, the light shielding plate 3031 is disposed near the non-blue pixel, and the light reflecting plate 3032 is disposed near the blue pixel 201. Illustratively, as shown in fig. 4, when the flexible barrier 303 is positioned between the blue pixel 201 and the red pixel 202, the light shielding plate 3031 is adjacent to the red pixel 202, and the light reflecting plate 3032 is adjacent to the blue pixel 201; when the flexible barrier 303 is positioned between the blue pixel 201 and the green pixel 203, the light shielding plate 3031 is close to the green pixel 203, and the light reflecting plate 3032 is close to the blue pixel 201.
In this embodiment, the light shielding plate 3031 and the light reflecting plate 3032 may be attached to each other or may maintain a predetermined distance between the planes, which is not limited in the embodiment of the present application. The two setting states of the light shielding plate 3031 and the light reflecting plate 3032 can be specifically shown in fig. 4 and fig. 5, fig. 4 is a schematic structural diagram of the fitting setting of the light shielding plate 3031 and the light reflecting plate 3032, and fig. 5 is a schematic structural diagram of keeping a preset distance between the light shielding plate 3031 and the light reflecting plate 3032 in a plane.
As shown in fig. 4, the light shielding plate 3031 and the light reflecting plate 3032 may be closely and symmetrically disposed with respect to the boundary line between the first organic region 301 and the second organic region 302 as a central line. In order to enable the flexible baffle 303 to bend towards the non-blue pixel smoothly, the thickness D of the light shielding plate 3031 and the light reflecting plate 3032 in the horizontal direction, which are arranged in a bonding manner, may be selected to be a suitable value within a range of 0.5 μm to 2 μm according to actual process requirements, which is not particularly limited in the embodiment of the present application.
As shown in fig. 5, the light shielding plate 3031 and the light reflecting plate 3032 may also maintain a predetermined distance between planes. The preset distance may be a suitable value selected from a range of 5 μm to 30 μm according to actual process requirements, which is not particularly limited in the embodiment of the present application.
In summary, in the flexible display panel provided by the embodiment of the present application, since the plurality of flexible baffles 303 are disposed in the organic layer 30 in the encapsulation layer 3, and the first organic region 301 and the second organic region 302 are disposed on two sides of each flexible baffle 303, respectively. The elastic modulus of the material used in the first organic region 301 is greater than that of the material used in the second organic region 302, so that when the flexible display panel is in a bending state, the first organic region 301 and the second organic region 302 can deform to different degrees, the flexible baffle 303 can be extruded to bend towards the non-blue pixel, so that the bent flexible baffle 303 can shield the non-blue pixel to increase attenuation of the non-blue pixel, the phenomenon of yellowing in the bending region of the flexible display panel can be effectively reduced, and the display effect is improved. Therefore, moisture can be effectively prevented from entering the light-emitting layer 2, so that the packaging effect of the packaging layer 3 is enhanced, and the reliability of the flexible display panel is improved.
