Specific embodiment

In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.

Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.In the absence of conflict, following embodiment and implementation Feature in example can be combined with each other.

Fig. 1 is the structural schematic diagram for the flexible display panels that the embodiment of the present invention one provides;Fig. 2 is that pixel limits in Fig. 1 The structural schematic diagram of layer.

Please refer to Fig. 1-Fig. 2, the present embodiment provides a kind of flexible display panels, including be stacked flexible base board 10, Buffer layer 20, planarization layer 30, first electrode layer 40, pixel confining layer 50, the second electrode lay 60, thin-film encapsulation layer 70;Pixel Confining layers 50 include pixel region 51 and the non-pixel areas 52 for surrounding pixel region 51.Flexible display panels further include: rigid transparent branch Bracer 80, rigid transparent supporting block 80 is between the second electrode lay 60 and thin-film encapsulation layer 70, and rigid transparent supporting block 80 Position it is corresponding with pixel region 51.

Specifically, flexible display panels generally include flexible base board 10, buffer layer 20, planarization layer 30, first electrode layer 40, pixel confining layer 50, the second electrode lay 60, thin-film encapsulation layer 70, for the flexible display panels shown in Fig. 1, these layers from Under supreme be followed successively by flexible base board 10, buffer layer 20, planarization layer 30, first electrode layer 40, pixel confining layer 50, second electrode Layer 60, thin-film encapsulation layer 70, wherein first electrode layer 40 can be anode electrode layer, and the second electrode lay 60 can be cathode electricity Pole layer, or, first electrode layer 40 is negative electrode layer, the second electrode lay 60 is anode electrode layer.In the present embodiment, the first electricity Pole layer 40 is anode electrode layer, and the second electrode lay 60 is negative electrode layer.

Referring to Fig. 2, pixel confining layer 50 limits pixel region 51, and pixel region 51 is surrounded by non-pixel areas 52, and in picture Organic luminous layer is provided in plain area 51.After flexible display panels are powered, hole and electronics are in first electrode layer 40 and the second electricity It is mobile towards organic luminous layer under the driving for the electric field that pole layer 60 is formed, and combined in organic luminous layer, so that organic light emission Layer shines.

Rigid transparent supporting block 80 is corresponding with the pixel region 51 of flexible display panels, i.e., rigid transparent supporting block 80 with it is organic Luminescent layer is corresponding, when flexible display panels bending, the pixel of the support of rigid transparent supporting block 80 and protection flexible display panels Area 51, so that pixel region 51 is not bent, non-pixel areas is bent, to prevent the corresponding the second electrode lay of pixel region 51 60 the phenomenon that being removed with thin-film encapsulation layer 70 or the second electrode lay 60 and organic luminous layer, it is ensured that flexible display panels it is normal It uses.

Rigid transparent supporting block 80 is generally laminated structure, has certain rigidity, to ensure when flexible display panels are curved Rigid transparent supporting block 80 will not be bent when folding.In addition, rigid transparent supporting block 80 is generally by transparent inorganic material, or Other transparent rigid material production, for example, rigid transparent supporting block 80 is to nitrogenize silico briquette made of silicon nitride, or serve as reasons Silicon oxide chunks made of silica.Or using the production of the material of production first electrode layer 40 or the second electrode lay 60, originally This is not construed as limiting in inventive embodiments.

In the above-described embodiments, rigid transparent supporting block 80 primarily serves the support and protective effect to pixel region 51, because This, in order to preferably support and protect pixel region 51, the area of rigid transparent supporting block 80 generally can be than the area of pixel region 51 Bigger, in an optional embodiment, rigid transparent supporting block 80 covers pixel region 51 relative to the projection of pixel region 51.Just Property projection of the transparent support block 80 in pixel confining layer 50 cover pixel region 51, so as to pass through rigid transparent supporting block 80 Pixel region 51 is effectively supported and protected.Furthermore, it is necessary to supplement, the area of rigid transparent supporting block 80 also can not mistake Greatly, the bendable folding endurance of flexible display panels is influenced to prevent rigid transparent supporting block 80.

In the above-described embodiments, the shape of rigid transparent supporting block 80 can be identical as the shape of pixel region 51, can not It is identical, it need to only guarantee that the corresponding pixel region of rigid transparent supporting block 80 is not bent when flexible display panels bending.?
