Description

Technical Field

[0001] This application belongs to the field of electronic product technology, and in particular relates to a display panel and display device. Background Technology

[0002] With the development of display technology, display panels have been gradually applied to various industries. However, due to limitations in certain specialized fields, such as wearable display panels, stretchable display panels have emerged. Currently, stretchable display panels mostly use OLED (Organic Light Emitting Diode) technology. Compared with traditional LCD (Liquid Crystal Display), OLED can achieve flexible, thin, and transparent displays, and features fast response speed, high electro-optical conversion efficiency, low heat generation, high contrast, and energy saving.

[0003] Due to the structural limitations of existing display panels, the distance between pixels increases and the pixel density decreases during the stretching process, resulting in poor display performance.

[0004] Therefore, there is an urgent need for a new display panel and display device. Summary of the Invention

[0005] This application provides a display panel and a display device. The movable light-emitting units can be moved to the interval between adjacent light-emitting groups to emit light and display, ensuring the distribution density of the light-emitting units of the stretched display panel, thereby ensuring the display effect of the stretched display panel and improving the user experience.

[0006] One embodiment of this application provides a display panel, including: a substrate; a light-emitting functional layer disposed on one side of the substrate, wherein the light-emitting functional layer includes a plurality of light-emitting groups spaced apart by stretching portions along a direction parallel to the plane of the substrate, and the light-emitting groups include at least three light-emitting units stacked together along a direction perpendicular to the plane of the substrate; within the light-emitting groups, at least two of the light-emitting units can move along a direction parallel to the plane of the substrate, and the moving directions of the at least two light-emitting units are different, so that the orthographic projections of the moved light-emitting units on the substrate do not overlap.

[0007] According to one aspect of this application, the light-emitting group includes at least three light-emitting units with different light-emitting colors.

[0008] According to one aspect of this application, the light-emitting unit includes a first electrode layer and a light-emitting material layer stacked along a direction perpendicular to the plane of the substrate; the light-emitting unit further includes a locking layer disposed on the side of the first electrode layer and the light-emitting material layer; preferably, in the same light-emitting group, the locking layers in two adjacent light-emitting units are disposed on different side of the first electrode layer and the light-emitting material layer.

[0009] According to one aspect of this application, the locking layer comprises an inorganic layer; preferably, the inorganic layer comprises at least one of silicon nitride, silicon oxide, and silicon oxynitride.

[0010] According to one aspect of this application, within two adjacent light-emitting groups, the movable directions of adjacent light-emitting units are different along a direction parallel to the plane where the substrate is located.

[0011] According to one aspect of this application, in a direction perpendicular to the plane of the substrate, the light-emitting group includes a first light-emitting unit, a second light-emitting unit, a third light-emitting unit, and a fourth light-emitting unit stacked together, the fourth light-emitting unit being away from the substrate relative to the first light-emitting unit; in a direction parallel to the plane of the substrate, the second light-emitting unit is movable relative to the first light-emitting unit in a first direction, the third light-emitting unit is movable relative to the first light-emitting unit in a second direction, and the fourth light-emitting unit is movable relative to the first light-emitting unit in the first direction, the first direction and the second direction intersecting.

[0012] According to one aspect of this application, the light-emitting group includes a red light-emitting unit, a green light-emitting unit, and a blue light-emitting unit; at least one of the orthographic projection shape and size of the red light-emitting unit, the green light-emitting unit, and the blue light-emitting unit on the substrate is different; preferably, the orthographic projection shape of the red light-emitting unit, the green light-emitting unit, and the blue light-emitting unit on the substrate is at least one of a rectangle, a cross, a trapezoid, and a rhombus.

[0013] According to one aspect of this application, the light-emitting functional layer further includes a second electrode layer covering the side of each of the light-emitting groups facing away from the substrate, the second electrode layer having a first perforation.

[0014] According to one aspect of this application, it further includes an encapsulation layer disposed on the side of the second electrode layer opposite to the substrate; the encapsulation layer includes at least one organic encapsulation layer and at least one inorganic encapsulation layer, the inorganic encapsulation layer having a second perforation.

[0015] In another aspect, the present invention provides a display device, comprising: the display panel described in any of the above embodiments.

[0016] Compared with the prior art, the display panel provided in this embodiment of the invention includes a substrate and a light-emitting functional layer. Since at least two light-emitting units can move in a direction parallel to the plane of the substrate within the light-emitting group, when the display panel is stretched, the light-emitting units within the light-emitting group can be driven to move in different directions respectively. Furthermore, because a stretching part is provided between the light-emitting groups, the stretching part will also be stretched and lengthened after the display panel is stretched, providing space for the moving light-emitting units. The orthographic projections of each light-emitting unit on the substrate after the movement do not overlap, that is, the moving light-emitting units can move to the interval between adjacent light-emitting groups to emit light and display, ensuring the distribution density of light-emitting units in the stretched display panel, thereby ensuring the display effect of the display panel after stretching and improving the user experience.

Therefore, this application is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in this application can be combined with each other without contradiction.

[0034] This application provides a display panel and a display device, which will be described below in conjunction with the accompanying drawings. Figures 1 to 10 Various embodiments of the display panel and display device will be described.

[0035] Please see Figures 1 to 3 The present application provides a display panel including: a substrate 1; a light-emitting functional layer 2 disposed on one side of the substrate 1, and the light-emitting functional layer 2 including a plurality of light-emitting groups 20 spaced apart by stretching portions 3 along a direction parallel to the plane of the substrate 1, and the light-emitting group 20 including at least three light-emitting units F stacked together along a direction perpendicular to the plane of the substrate 1; within 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 at least two light-emitting units F are different, so that the orthographic projections of each light-emitting unit F on the substrate 1 after moving do not coincide.

[0036] The display panel provided in this embodiment of the invention includes a substrate 1 and a light-emitting functional layer 2. Since at least two light-emitting units F can move along a direction parallel to the plane of the substrate 1 within the light-emitting group 20, when the display panel is stretched, the light-emitting units F within the light-emitting group 20 can move in different directions respectively. Furthermore, since a stretching part 3 is provided between the light-emitting groups 20, the stretching part 3 will also be stretched and lengthened after the display panel is stretched, providing space for the moving light-emitting units F. The orthographic projections of each light-emitting unit F on the substrate 1 after the movement do not overlap, that is, the moving light-emitting units F can move to the interval between adjacent light-emitting groups 20 respectively to emit light and display, ensuring the distribution density of light-emitting units F in the stretched display panel, thereby ensuring the display effect of the display panel after stretching and improving the user experience.

[0037] In this embodiment, the stretching part 3 can be made of an organic material with good stretching properties, such as epoxy resin, hexamethyl dimethyl silyl ether, polyimide, or silicone.

[0038] Within the light-emitting group 20, at least two light-emitting units F can move in a direction parallel to the plane of the substrate 1, and the movement directions of the at least two light-emitting units F are different. Specifically, this can be achieved by setting limiting structures such as blocks or baffles to restrict the movement direction of the light-emitting units F, without any special limitation. Each light-emitting unit F can be driven to emit light independently, and the arrangement of the light-emitting units F before stretching the display panel and after stretching can be controlled separately.

[0039] Before the display panel is stretched, only the light-emitting unit F at the top of the light-emitting group 20 needs to be controlled. The light-emitting units F at the bottom do not emit light. After the display panel is stretched, the light-emitting units F move, and the light-emitting units F at the bottom can be exposed. That is, the orthographic projections of each light-emitting unit F after the movement do not overlap on the substrate 1, so that each light-emitting unit F can emit light and display, thus ensuring the display effect after the display panel is stretched.

[0040] The substrate 1 provided in this embodiment of the invention can be made of materials with good tensile properties such as thermoplastic polyurethane rubber and silicone, which are easy to stretch.

[0041] like Figure 1 and 2 As shown, in some optional embodiments, the light-emitting group 20 includes at least three light-emitting units F with different colors. Specifically, the light-emitting units F with different colors can be 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 evenly in the new arrangement of light-emitting units F formed after the display panel is stretched, and so that the red light-emitting unit R, the green light-emitting unit G, and the blue light-emitting unit B can be mixed to produce white light.

[0042] In some optional embodiments, the light-emitting unit F includes a first electrode layer 21 and a light-emitting material layer 22 stacked along a direction perpendicular to the plane of the substrate 1; the light-emitting unit F also includes a locking layer 23 disposed on the side of the first electrode layer 21 and the light-emitting material layer 22.

[0043] It should be noted 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 into a whole, so as to facilitate the movement of the first electrode layer 21 and the light-emitting material layer 22 as a whole. That is, the locking layer 23 can connect the sides of the first electrode layer 21 and the light-emitting material layer 22 together. The locking layer 23 can be made of inorganic materials. For example, the locking layer 23 includes an inorganic layer, which includes at least one of silicon nitride, silicon oxide, and silicon oxynitride.

[0044] 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 in the light-emitting unit F can be located on different sides of the first electrode layer 21 and the light-emitting material layer 22, depending on the movable direction of the light-emitting unit F. Specifically, within the same light-emitting group 20, the locking layers 23 in two adjacent light-emitting units F are located on different sides of the first electrode layer 21 and the light-emitting material layer 22. The plane where the locking layer 23 is located can be perpendicular to the moving direction of the light-emitting unit F to ensure the fixing effect of the locking layer 23 on the first electrode layer 21 and the light-emitting material layer 22.

[0045] Please see Figures 4 to 6 In some optional embodiments, within 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.

[0046] It is understandable that if adjacent light-emitting units F have the same movable direction, the lower light-emitting unit F will be blocked by the light-emitting unit F above it, affecting the display effect of the stretched display panel. By making the movable directions of adjacent light-emitting units F different, the moving light-emitting units F are distributed in different directions, thereby increasing the distribution density of light-emitting units F in different directions, i.e., PPI (Pixels Per Inch), and improving the display effect of the display panel.

[0047] For example, one of two adjacent light-emitting units F can move along the first direction Y, and the other can move along the second direction X. For instance, when the display panel is stretched only in the first direction Y, the light-emitting unit F that can move along the first direction Y is moved accordingly. Normally, the uppermost light-emitting unit F in the light-emitting group 20 does not need to move and can remain in its original position. The lower light-emitting unit F moves along the first direction Y to the interval between the uppermost light-emitting units F in the two adjacent light-emitting groups 20, thereby increasing the distribution density of light-emitting units F in the first direction Y of the display panel. Similarly, when the display panel is stretched only in the second direction X, the light-emitting units F that can move along the second direction X can also move to the interval between the uppermost light-emitting units F in the two adjacent light-emitting groups 20 in the second direction X, thereby increasing the distribution density of light-emitting units F in the second direction X of the display panel.

[0048] Optionally, depending on the stretching degree of the display panel, i.e., the size of the gap formed between two adjacent light-emitting groups 20 after stretching, one or more light-emitting units F in the light-emitting group 20 can be moved to the same gap. For example, when the display panel is stretched by one pixel distance, i.e., the gap formed between two adjacent light-emitting groups 20 can accommodate one light-emitting unit F, only one light-emitting unit F can be moved to the gap formed between the two adjacent light-emitting groups 20. When the display panel is stretched by two pixel distances, only two light-emitting units F can be moved to the gap formed between the two adjacent light-emitting groups 20 to ensure the pixel density of the display panel.

[0049] Please see Figures 7 to 10 In some optional embodiments, along the direction perpendicular to the plane of the substrate 1, 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 stacked together, with the fourth light-emitting unit F4 being away from the substrate 1 relative to the first light-emitting unit F1; along the direction parallel to the plane of the substrate 1, the second light-emitting unit F2 can move relative to the first light-emitting unit F1 along a first direction Y, the third light-emitting unit F3 can move relative to the first light-emitting unit F1 along a second direction X, and the fourth light-emitting unit F4 can move relative to the first light-emitting unit F1 along a first direction Y, with the first direction Y intersecting the second direction X.

[0050] It should be noted that in this embodiment, the second light-emitting unit F2 can move relative to the first light-emitting unit F1 along the first direction Y, which does not mean that the second light-emitting unit F2 cannot move relative to the first light-emitting unit F1 along the second direction X. The same applies to the third light-emitting unit F3 and the fourth light-emitting unit F4. The specific settings need to be made according to actual needs. When stretching in the first direction Y and the second direction X, the multiple light-emitting units F under the first light-emitting unit F1 are divided into two groups and extend towards the second direction X. The extended light-emitting unit F combination is also a multi-layer structure. When stretching in the first direction Y, new light-emitting units F will continue to be stretched out, so that the entire screen is made up of light-emitting units F.

[0051] For example, when the display panel is stretched along the second direction X, the first light-emitting unit F1 and the second light-emitting unit F2 can be kept stationary, while the third light-emitting unit F3 and the fourth light-emitting unit F4 move relative to the first light-emitting unit F1 along the second direction X. Then, when the display panel is stretched along the first direction Y, the second light-emitting unit F2 and the third light-emitting unit F3 can be moved along the first direction Y to fill the gaps created by the light-emitting group 20 in the first direction Y. Figure 7 and Figure 8 As shown. Similarly, when the display panel is stretched along the first direction Y, the changes 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 before and after stretching are as follows. Figure 9 and Figure 10 As shown.

[0052] It is understandable that, in order to ensure uniform light emission from the display panel, 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 adjacent light-emitting groups 20 have different light-emitting colors and shapes.

[0053] For example, within one 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 an adjacent 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 light-emitting colors 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 can also be combined in other ways, and can be selected according to actual needs without special limitations.

[0054] Optionally, 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 have different orthogonal projection shapes and sizes on the substrate 1.

[0055] In this embodiment, by making at least one of the orthographic projection shape and 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 different, it is possible to ensure that after the display panel is stretched, the red light-emitting unit R, the green light-emitting unit G, and the blue light-emitting unit B can be evenly distributed and cover the entire display panel.

[0056] Optionally, the orthographic projection shape of the red light-emitting unit R, the green light-emitting unit G, and the blue light-emitting unit B on the substrate 1 is at least one of a rectangle, a cross, a trapezoid, or a rhombus.

[0057] In some optional embodiments, the light-emitting functional layer 2 further includes a second electrode layer 4 covering the side of each light-emitting group 20 away from the substrate 1, and the second electrode layer 4 is provided with a first perforation.

[0058] Understandably, by setting the first perforation, the tensile properties of the second electrode layer 4 can be improved, avoiding problems such as tearing of the second electrode layer 4 when the display panel is stretched, thus improving the stability of the display panel. The first perforation can be elongated, circular, elliptical, or other shapes, without any particular limitation. The first perforation can be formed through processes such as etching.

[0059] In some optional embodiments, the display panel further includes an encapsulation layer disposed on the side of the second electrode layer 4 away from the substrate 1; the encapsulation layer includes at least one organic encapsulation layer and at least one inorganic encapsulation layer, the inorganic encapsulation layer having a second perforation.

[0060] In this embodiment, the organic encapsulation layer can be made of organic materials with good tensile properties, such as organic resin, while the inorganic encapsulation layer needs to be provided with a second hollow hole to improve the tensile properties of the inorganic encapsulation layer and avoid problems such as tearing of the inorganic encapsulation layer when the display panel is stretched, thus ensuring the encapsulation effect of the display panel.
