The embodiments provided in the examples of the present application may be combined with each other without contradiction.
The embodiment of the application provides a display panel and a display device, and the embodiments of the display panel and the display device will be described with reference to fig. 1 to 10.
Referring to fig. 1 to 3, a display panel provided in an embodiment of the present application includes: a substrate 1; the light-emitting functional layer 2 is arranged on one side of the substrate 1, the light-emitting functional layer 2 comprises a plurality of light-emitting groups 20 which are arranged at intervals through the stretching part 3 along the direction parallel to the plane of the substrate 1, and the light-emitting groups 20 comprise at least three light-emitting units F which are arranged in a lamination manner along the direction perpendicular to the plane of the substrate 1; in the light emitting group 20, at least two light emitting units F can move along a direction parallel to the plane of the substrate 1, and the moving directions of the at least two light emitting units F are different, so that the orthographic projections of the moved light emitting units F on the substrate 1 do not overlap.
The display panel provided by the embodiment of the invention comprises the substrate 1 and the luminous functional layer 2, because at least two luminous units F can move along the direction parallel to the plane where the substrate 1 is positioned in the luminous groups 20, when the display panel stretches, the luminous units F in the luminous groups 20 can be driven to move in different directions respectively, and because the stretching part 3 is arranged between the luminous groups 20, after the display panel stretches, the stretching part 3 can be stretched to be longer, a space is provided for the moving luminous units F, the orthographic projection of each luminous unit F after the movement on the substrate 1 is not overlapped, namely, the moving luminous units F can be respectively moved to the interval between the adjacent luminous groups 20 to perform luminous display, so that the distribution density of the luminous units F of the stretched display panel is ensured, the display effect of the display panel after the stretching is further ensured, and the use experience of a user is improved.
In this embodiment, the stretching portion 3 may be made of an organic material having good stretching properties, such as epoxy resin, hexamethyldisiloxane, polyimide, or silica gel.
In the light emitting group 20, at least two light emitting units F may move along a direction parallel to the plane of the substrate 1, and the moving directions of the at least two light emitting units F are different, which may be specifically achieved by setting a limit structure such as a stopper, a baffle, etc. to limit the moving direction of the light emitting unit F, and is not particularly limited. Each light emitting unit F can be driven to emit light respectively, and the arrangement of the light emitting units F before stretching and the control of the light emitting units F after stretching are controlled respectively.
Before the display panel is stretched, only the uppermost light emitting unit F of the light emitting group 20 needs to be controlled, the lower light emitting unit F does not emit light, and after the display panel is stretched, the lower light emitting unit F can be exposed due to movement of the light emitting unit F, that is, orthographic projections of the moved light emitting units F on the substrate 1 are not overlapped, so that the light emitting units F can realize light emitting display, and a display effect of the stretched display panel is ensured.
The substrate 1 provided by the embodiment of the invention can be made of materials with good tensile properties such as thermoplastic polyurethane rubber, silica gel and the like, and is convenient to stretch.
As shown in fig. 1 and 2, in some alternative embodiments, the light emitting group 20 includes at least three light emitting units F with different light emitting colors, where the light emitting units F with different colors may be specifically a red light emitting unit R, a green light emitting unit G, and a blue light emitting unit B, so that each light emitting unit F emits light uniformly in a new light emitting unit F arrangement formed after the display panel is stretched, and it is convenient for the red light emitting unit R, the green light emitting unit G, and the blue light emitting unit B to mix into white light.
In some alternative embodiments, the light emitting unit F includes a first electrode layer 21 and a light emitting material layer 22 stacked in a direction perpendicular to a plane in which the substrate 1 is located; the light emitting unit F further includes a locking layer 23 provided at a side of the first electrode layer 21 and the light emitting material layer 22.
Note that the locking layer 23 is provided to fix the first electrode layer 21 and the light emitting material layer 22 of the light emitting unit F as a unit, so that the first electrode layer 21 and the light emitting material layer 22 are moved as a unit, that is, the locking layer 23 may connect the sides of the first electrode layer 21 and the light emitting material layer 22 together, and the locking layer 23 may be made of an inorganic material, for example, the locking layer 23 may include an inorganic layer including at least one of silicon nitride, silicon oxide, and silicon oxynitride.
Considering that the sides of the first electrode layer 21 and the light emitting material layer 22 where the locking layer 23 is located may affect the movement of the light emitting unit F, the locking layer 23 within the light emitting unit F may be provided at different sides of the first electrode layer 21 and the light emitting material layer 22 according to the movable direction of the light emitting unit F. Specifically, in the same light-emitting group 20, the locking layers 23 in two adjacent light-emitting units F are disposed on different sides of the first electrode layer 21 and the light-emitting material layer 22, and the plane on which the locking layer 23 is located may be specifically perpendicular to the moving direction of the light-emitting unit F where it is located, so as to ensure the fixing effect of the locking layer 23 on the first electrode layer 21 and the light-emitting material layer 22.
Referring to fig. 4 to 6, in some alternative embodiments, in two adjacent light emitting groups 20, the movable directions of adjacent light emitting units F are different along a direction parallel to the plane of the substrate 1.
It can be understood that if the movable directions of the adjacent light emitting units F are the same, the light emitting units F located below are blocked by the light emitting units F located above the adjacent light emitting units F, which affects the display effect of the stretched display panel. By making the movable directions of the adjacent light emitting units F different to disperse the movable light emitting units F in different directions, the distribution density of the light emitting units F in different directions, i.e., PPI (pixel Per Inch) is increased, so as to improve the display effect of the display panel.
For example, one of the two adjacent light emitting units F may move along the first direction Y, and the other may move along the second direction X, for example, when the display panel is stretched only in the first direction Y, the light emitting units F that may move along the first direction Y are driven to move correspondingly, while the light emitting unit F located at the uppermost position in the light emitting group 20 is not required to move, and the light emitting unit F located at the lower position may move along the first direction Y into the interval between the light emitting units F located at the uppermost position in the two adjacent light emitting groups 20, so as to increase the distribution density of the light emitting units F of the display panel in the first direction Y. Similarly, when the display panel is stretched only in the second direction X, the light emitting units F movable in the second direction X may be moved to within the interval in the second direction X between the light emitting units F located uppermost in the adjacent two light emitting groups 20 to increase the distribution density of the light emitting units F of the display panel in the second direction X.
Alternatively, one or more light emitting units F in the light emitting groups 20 may be selectively moved to within the same interval according to the stretching degree of the display panel, i.e., the size of the interval formed between adjacent two light emitting groups 20 of the display panel after stretching. For example, when the display panel is stretched by one pixel distance, that is, the interval formed between the adjacent two light emitting groups 20, it is possible to control only one light emitting unit F to move into the interval formed between the adjacent two light emitting groups 20 while accommodating one light emitting unit F. When the display panel is stretched by two times the pixel distance, only the two light emitting units F may be controlled to move into the interval formed between the adjacent two light emitting groups 20 to ensure the pixel density of the display panel.
Referring to fig. 7 to 10, in some alternative embodiments, in a direction perpendicular to a plane in which the substrate 1 is located, the light emitting group 20 includes a first light emitting unit F1, a second light emitting unit F2, a third light emitting unit F3, and a fourth light emitting unit F4 that are stacked, and the fourth light emitting unit F4 is far from the substrate 1 with respect to the first light emitting unit F1; in a direction parallel to the plane of the substrate 1, the second light emitting unit F2 is movable in a first direction Y with respect to the first light emitting unit F1, the third light emitting unit F3 is movable in a second direction X with respect to the first light emitting unit F1, and the fourth light emitting unit F4 is movable in the first direction Y with respect to the first light emitting unit F1, the first direction Y and the second direction X intersecting.
It should be noted that, in this embodiment, the second light emitting unit F2 may move along the first direction Y relative to the first light emitting unit F1, which does not mean that the second light emitting unit F2 may not move along the second direction X relative to the first light emitting unit F1, and the third light emitting unit F3 and the fourth light emitting unit F4 are similarly configured as needed, and specifically, when the first direction Y and the second direction X stretch, the plurality of light emitting units F under the first light emitting unit F1 are equally divided into two groups and extend toward the second direction X, the combination of the extended light emitting units F is also a multi-layer structure, and when the first direction Y stretches, the new light emitting unit F is continuously stretched, so that the whole screen is the light emitting unit F.
For example, when the display panel is stretched in the second direction X, the first light emitting unit F1 and the second light emitting unit F2 may be kept stationary, the third light emitting unit F3 and the fourth light emitting unit F4 may be moved in the second direction X with respect to the first light emitting unit F1, and then when the display panel is stretched in the first direction Y, the second light emitting unit F2 and the third light emitting unit F3 may be moved in the first direction Y to fill the space generated by the light emitting group 20 in the first direction Y, as shown in fig. 7 and 8. Similarly, when the display panel is stretched in the first direction Y, the first, second, third, and fourth light emitting units F1, F2, F3, and F4 are changed before and after stretching as shown in fig. 9 and 10.
It will be appreciated that, in order to ensure uniform light emission of the display panel, the light emission colors and shapes of the first light emitting unit F1, the second light emitting unit F2, the third light emitting unit F3, and the fourth light emitting unit F4 in the adjacent light emitting groups 20 are different.
For example, in the light-emitting group 20, the first light-emitting unit F1 is a green light-emitting unit G, the second light-emitting unit F2 is a blue light-emitting unit B, the third light-emitting unit F3 is a blue light-emitting unit B, and the fourth light-emitting unit F4 is a red light-emitting unit R. In the adjacent other light emitting group 20, the first light emitting unit F1 is a red light emitting unit R, the second light emitting unit F2 is a green light emitting unit G, the third light emitting unit F3 is a blue light emitting unit B, and the fourth light emitting unit F4 is a red light emitting unit R. Of course, the emission colors of the first, second, third and fourth light emitting units F1, F2, F3 and F4 may be other combinations, and may be selected according to actual needs, without particular limitation.
Alternatively, the light emitting group 20 includes a red light emitting unit R, a green light emitting unit G, and a blue light emitting unit B; the red light emitting unit R, the green light emitting unit G, and the blue light emitting unit B differ in at least one of the shape and the size of the orthographic projection on the substrate 1.
In this embodiment, at least one of the front projection shapes and the size of the red light emitting unit R, the green light emitting unit G and the blue light emitting unit B on the substrate 1 are different, so as to satisfy that the red light emitting unit R, the green light emitting unit G and the blue light emitting unit B can be uniformly distributed and spread over the whole display panel after the display panel is stretched.
Optionally, the orthographic projection shapes of the red light emitting unit R, the green light emitting unit G, and the blue light emitting unit B on the substrate 1 are at least one of rectangular, cross, trapezoid, and diamond.
In some alternative embodiments, the light-emitting functional layer 2 further includes a second electrode layer 4 covering a side of each light-emitting group 20 facing away from the substrate 1, where the second electrode layer 4 is provided with a first hollowed-out hole.
It can be appreciated that by setting the first hollow hole, the stretching performance of the second electrode layer 4 can be improved, the problem that the second electrode layer 4 is torn when the display panel stretches is avoided, the use stability of the display panel is improved, and the first hollow hole can be in a long strip shape, a round shape, an oval shape and the like and is not particularly limited. The first hollowed-out hole can be formed through etching and other processes.
In some alternative embodiments, the display panel further comprises an encapsulation layer provided on the side of the second electrode layer 4 facing away from the substrate 1; the packaging layer comprises at least one organic packaging layer and at least one inorganic packaging layer, and the inorganic packaging layer is provided with a second hollow hole.
In this embodiment, the organic packaging layer may be made of an organic material with good tensile properties, such as organic resin, and the inorganic packaging layer needs to be provided with a second hollow hole, so as to improve the tensile properties of the inorganic packaging layer, avoid the problem that the inorganic packaging layer is torn when the display panel is stretched, and ensure the packaging effect of the display panel.
