Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The invention will be described in more detail below with reference to the accompanying drawings. Like elements in the various figures are denoted by like reference numerals. For purposes of clarity, the various features in the drawings are not necessarily drawn to scale. Moreover, certain well-known elements may not be shown in the figures.
In the following description, numerous specific details of the invention, such as structure, materials, dimensions, processing techniques and techniques of components, are set forth in order to provide a more thorough understanding of the invention. However, as will be understood by those skilled in the art, the present invention may be practiced without these specific details.
Example 1:
as shown in fig. 1 to 7, the present embodiment provides a flexible display panel assembly, including:
a display structure layer 1, the display structure layer 1 having a first side 11 and a second side 12 opposite to each other, the display structure layer 1 being capable of being rolled from the first side 11 to the second side 12, so that a part of the display structure layer 1 is overlapped on a part of the display structure layer 1 close to the first side 11, and the first side 11 is closer to a rolling axis of the display structure layer 1 than the second side 12;
a support structure 2, at least part of the support structure 2 being formed of an elastic material, connected to the first edge 11 of the display structure layer 1, for supporting a part of the display structure layer 1 superposed on the support structure 2.
That is to say, the flexible display panel assembly of the present embodiment can be converted from the unfolded state (as shown in fig. 3) to the rolled state (as shown in fig. 2), and can also be converted from the rolled state to the unfolded state, where the unfolded state can enable the flexible display panel assembly to display better, and the rolled state can enable the flexible display panel assembly to be easily stored, so as to achieve the portable effect.
As shown in fig. 2, the display structure layer 1 in a rolled state has a support structure 2 connected to a first side 11 of the display structure layer 1 (which may be connected by an adhesive), that is, the support structure 2 is connected to a side of the display structure layer 1 close to the roll axis, so that at least a part of the display structure layer 1 is stacked on the support structure 2, and the support structure 2 is used for supporting the display structure layer 1 stacked thereon. Also, since at least a portion of the support structure 2 is formed of an elastic material, i.e., the support structure 2 is elastic, the support structure 2 may have a cushioning effect on the support of the display structure layer 1 stacked thereabout.
It should be noted that, if the first side 11 of the display structure layer 1 in the rolled state is not connected to the supporting structure 2 (corresponding to a flexible display panel in the prior art, as shown in fig. 1), the portion of the display structure layer 1 stacked near the first side 11 is given a certain supporting force by the display structure layer 1 near the first side 11, and another portion connected to the portion of the display structure layer 1 stacked near the first side 11 may be bent at the first side 11 due to no supporting force, as shown in a portion a in fig. 1, so that the display structure layer 1 is damaged at the bent portion, and the service life of the display structure layer 1 is further reduced.
In the flexible display panel assembly of this embodiment, because the supporting structure 2 is elastic, along with the curling degree of the display structure layer 1, the supporting structure 2 may transition the display structure layer 1 at the first edge 11 from supporting to not supporting, that is, the portion of the display structure layer 1 stacked on the supporting structure 2 is not supported from being fixed to suddenly having no supporting force, that is, the display structure layer 1 is not bent at the first edge 11 (i.e., the portion of the display structure layer 1 is absorbed to generate a step difference), thereby ensuring the performance of the display structure layer 1 and the service life of the display structure layer 1.
Preferably, the support structure 2 further comprises: an elastic structure layer 21 and a rigid structure layer 22 superposed with the elastic structure layer 21, the rigid structure layer 22 being closer to the winding shaft than the elastic structure layer 21.
Specifically, the elastic structure layer 21 is a rubber layer (e.g., si glue), and the rigid structure layer 22 may be a metal layer. It should be noted that the elastic structure layer 21 and the rigid structure layer 22 may be formed of other suitable materials.
In order to ensure the supporting performance of the supporting structure 2, the rigid structure layer 22 is disposed on one side of the supporting structure 2 close to the winding shaft, so as to ensure that the supporting structure 2 has a better supporting force for the supported portion of the display structure layer 1, that is, the display structure layer 1 near the first edge 11 is not bent on the premise of ensuring the normal winding of the display structure layer 1.
Specifically, the thickness of the elastic structure layer 21 is 10 to 250 micrometers, the thickness of the rigid structure layer 22 is 30 to 100 micrometers, and the thickness of the display structure layer 1 is 50 to 250 micrometers.
Preferably, the elastic structure layer 21 has a plurality of through holes 211 therein for dispersing stress generated after the elastic structure layer 21 is deformed.
Wherein, the supporting structure 2 has a supporting force for part of the display structure layer 1, and the part of the display structure layer 1 also has a force for the supporting structure 2, so that the supporting structure 2 with elasticity can be deformed. Since the curling shape of the display structure layer 1 is constant, the deformation degree of the support structure 2 is almost the same as the curling degree, so that the stress distribution generated in the support structure 2 after each curling is almost constant, and after the flexible display panel assembly is used for a certain time, the support structure 2 may be damaged, such as broken, due to the stress generated by the deformation. Therefore, the plurality of through holes 211 are disposed in the elastic structure layer 21 to disperse the stress generated after the elastic structure layer 21 is deformed, thereby prolonging the service life of the support structure 2.
In addition, the through holes 211 in the elastic structure layer 21 may be formed by patterning (patterning) with a mask, or may be formed by other suitable processes, which are not described herein again.
As can be seen from the above, the support structure 2 in the flexible display panel assembly of the present embodiment may be the following structure: the support structure 2 has only the elastic structure layer 21, and the elastic structure layer 21 has no through hole 211, as shown in fig. 4; the support structure 2 has only the elastic structure layer 21, and the elastic structure layer 21 has a through hole 211, as shown in fig. 5; the support structure 2 has an elastic structure layer 21 and a rigid structure layer 22, and the elastic structure layer 21 has no through hole 211. FIG. 6 is a schematic view; the support structure 2 has an elastic structure layer 21 and a rigid structure layer 22, and the elastic structure layer 21 has a through hole 211, as shown in fig. 7.
Preferably, the distance between two adjacent through holes 211 close to the first side 11 is smaller than the distance between two adjacent through holes 211 far from the first side 11.
Because the support structure 2 near the first edge 11 supports the part of the display structure layer 1 more than the support structure 2 far from the first edge 11 supports the part of the display structure layer 1, that is, the deformation stress of the support structure 2 near the first edge 11 is greater than that of the support structure 2 far from the first edge 11, the distance between two adjacent through holes 211 near the first edge 11 is smaller than that between two adjacent through holes 211 far from the first edge 11, so that the stress distribution of the elastic structure layer 21 can be better dispersed.
Specifically, if the diameter of each through hole 211 is D, the curling diameter of the structural layer 1 is D, and the distance from the adjacent two through holes 211 close to the first edge 11 to the adjacent two through holes 211 far from the first edge 11 is D, D + D, D +2D, etc. in sequence, as shown in fig. 5 and 7.
Preferably, the connection surface of the display structure layer 1 and the support structure 2 away from the winding shaft is smooth.
In other words, in order to better buffer the portion of the display structure layer 1 supported by the supporting structure 2, the connection surface between the display structure layer 1 and the supporting structure 2, which is far away from the winding shaft (i.e. the supporting surface between the display structure layer 1 and the supporting structure 2), is smooth, so that the display structure layer 1 near the first edge 11 can be further prevented from bending, and the performance of the display structure layer 1 can be further ensured.
Preferably, the side of the support structure 2 connected to the first side 11 has the same length as the first side 11 of the display structure layer 1.
Wherein the support structure 2 is connected to the whole first side 11 of the display structure layer 1, which further improves the support performance of the support structure 2, thereby ensuring the display performance of the flexible display panel assembly.
Preferably, the display structure layer 1 includes a flexible substrate, and a polarizer, a touch layer and a display layer located on one side of the flexible substrate.
One of the cases of the display structure layer 1 is as follows: the polarizer, the touch layer and the display layer are sequentially arranged from the position close to the flexible substrate to the position far away from the flexible substrate. Another case of the display structure layer 1 is: the touch layer, the polaroid and the display layer are sequentially arranged from the position close to the flexible substrate to the position far away from the flexible substrate. In addition, the touch layer may be formed in the display layer, or both the touch layer and the polarizer may be formed in the display layer. The structural layers can be bonded by optical cement.
In addition, in the flexible display panel assembly, in order to achieve the curling performance, the flexible substrate is formed of a polyimide material (PI), or the flexible substrate is a flexible glass. And the thickness of the flexible substrate may be 25-75 um. The curling radius of the display structure layer 1 can be 5mm-15mm, and the thickness of the display structure layer 1 can be 50um-250 um.
Further, the display structure layer 1 further includes a structure layer located on one side of the flexible substrate for improving the rigidity of the whole display structure layer 1, and the structure layer may be a metal layer.

the present embodiment provides a flexible display device including the flexible display panel assembly of embodiment 1.
Specifically, the display panel may be any product or component having a display function, such as an Organic Light Emitting Diode (OLED) display panel, electronic paper, a display, and a navigator.
