[0045] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0046] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0047] The utility model provides a light-emitting panel. Figure 1 This is a schematic diagram of the structure of a circular light-emitting area in a light-emitting panel provided by an embodiment of the utility model. Figure 2 This is a schematic diagram of the structure of a basic light-emitting unit provided by an embodiment of the utility model, referring to Figure 1 and Figure 2 , the light emitting panel includes:

[0048] A plurality of basic light-emitting units 10 of the same shape and area; at least some of the basic light-emitting units 10 are arranged in a circular array along the same position point to form a circular light-emitting area 100; the same position point is the center point of the circular light-emitting area 100; each basic light-emitting unit includes a plurality of sub-pixels;

[0049] A control unit, the control unit is electrically connected to each sub-pixel, and each sub-pixel is independently controlled by the control unit;

[0050] Among them, the pattern of the sub-pixel p in the same basic light-emitting unit 10 is a pattern formed by the initial pattern of the basic light-emitting unit 10 based on the quasi-crystal segmentation method, and the patterns of the sub-pixels p in two adjacent basic light-emitting units 10 are symmetrically arranged about the same symmetry axis.

[0051] Specifically, in the basic light-emitting unit 10, the light-emitting colors of different sub-pixels p can be the same or different. For example, the colors of the sub-pixels p in the basic light-emitting unit 10 can all be selected as red, which has the characteristics of better display effect and stronger prompting. Of course, other colors can also be selected. The light-emitting panel may include a quasi-circular light-emitting area 100, or may include multiple quasi-circular light-emitting areas 100. If the light-emitting panel includes a quasi-circular light-emitting area 100, all the basic light-emitting units 10 may be arranged in a circular array along the same position point to form the quasi-circular light-emitting area 100; or part of the basic light-emitting units 10 may be arranged in a circular array along the same position point, and the remaining basic light-emitting units 10 form other graphics, or are scattered around the quasi-circular light-emitting area 100. The quasi-circular light-emitting area 100 can be understood as a polygonal light-emitting area with a number of sides greater than a preset value.

[0052] Compared with crystals, which can be described by the infinite repetition of a unit cell in space, quasicrystals can be defined as follows: quasicrystals are composed of two (or more) "primitive cells" that are infinitely repeated in space, and the arrangement of these "primitive cells" has long-range quasi-periodic translational order and long-range directional order. Quasicrystals have a long-range ordered atomic arrangement similar to that of crystals, but quasicrystals do not have the translational symmetry of crystals. The arrangement and spacing of particles in the quasicrystal structure will show certain differences in various properties when observed and studied in different directions, so it is anisotropic. However, the different parts of the quasicrystal divided out still have the same structural characteristics as the overall structure when enlarged or reduced, so the quasicrystal properties reflected macroscopically are still uniform. The mathematical constant τ, that is, the golden ratio number 1.618, is hidden in the figures divided out of the quasicrystal, which has a certain aesthetics.

[0053] The initial pattern of the basic light-emitting unit 10 is divided by a quasi-crystal division method to form a pattern of sub-pixels p, so that the overall arrangement pattern of sub-pixels p in the basic light-emitting unit 10 has the basic properties of quasi-crystals, thereby making the lighting effect of the light-emitting panel more diversified and personalized. In addition, the patterns of sub-pixels p in two adjacent basic light-emitting units 10 are symmetrically arranged along the same symmetry axis, so that the arrangement of sub-pixels p in the quasi-circular light-emitting area 100 has regularity, which is convenient for improving the regularity of lighting the light-emitting panel. In addition, the area where each sub-pixel p is located is an independent light-emitting area. By adjusting the brightness value of the light-emitting area and designing the light-emitting combination of each light-emitting interval, a variety of patterns can be formed, and static and dynamic effects such as multiple spatial dimensions can also enrich the lighting effect of the light-emitting panel.

[0054] The light-emitting panel provided by the embodiment of the utility model includes: a plurality of basic light-emitting units 10 of the same shape and area, and a control unit connected to each sub-pixel in the basic light-emitting unit; at least part of the basic light-emitting units 10 are arranged in a circular array along the same position point to form a circular light-emitting area 100. The initial pattern of the basic light-emitting unit 10 is divided by a quasi-crystal division method to form a pattern of sub-pixels p, so that the overall arrangement pattern of sub-pixels p in the basic light-emitting unit 10 has the basic properties of quasi-crystals, thereby making the lighting effect of the light-emitting panel more diversified and personalized. In addition, the patterns of sub-pixels p in two adjacent basic light-emitting units 10 are symmetrically arranged along the same symmetry axis, so that the arrangement of sub-pixels p in the circular light-emitting area 100 has regularity, which is convenient for improving the regularity of lighting of the light-emitting panel; in addition, through the independent control of each sub-pixel by the control unit, the area where each sub-pixel is located is an independent light-emitting area, so that a variety of patterns can be formed by adjusting the brightness of the light-emitting area and designing the light-emitting combination of each light-emitting interval, and static and dynamic effects such as multiple spatial dimensions can also enrich the lighting effect of the light-emitting panel.

[0055] On the basis of the above embodiments, in one embodiment of the present invention, the pattern of the sub-pixel p in the basic light-emitting unit 10 includes at least two of an acute triangle, an obtuse triangle and a right triangle. The pattern of the basic light-emitting unit 10 is determined according to at least two different shapes of sub-pixel p patterns, so that the pattern of the basic light-emitting unit 10 is more abundant, thereby enriching the lighting effect of the light-emitting panel. For example, reference Figure 2 , the basic light-emitting unit 10 includes fourteen sub-pixels p from p1 to p14. The graphics of the sub-pixels p in the basic light-emitting unit 10 include acute triangles, obtuse triangles and right triangles; for example, the graphics of sub-pixels p1 and p7 are obtuse triangles, the graphics of sub-pixels p2 and p3 are acute triangles, and the graphics of sub-pixels p11 and p12 are right triangles. In addition, in the basic light-emitting unit 10, the area of ​​the sub-pixel p close to the center point is smaller than the area of ​​the sub-pixel p far from the center point. For example, the distance from sub-pixel p1 to the center point is smaller than the distance from sub-pixel p10 to the center point, so the area of ​​sub-pixel p1 is smaller than the area of ​​sub-pixel p10.

[0056] On the basis of the above embodiments, in one embodiment of the present utility model, the shape of the quasi-circular light-emitting area 100 is a polygon with n sides; n is an even number greater than 4; the shape of the quasi-circular light-emitting area 100 is composed of at least n basic light-emitting units 10 with a triangular outer contour; the distance between two adjacent basic light-emitting units 10 is 10μm to 800μm.

[0057] It can be understood that the shape of the quasi-circular light-emitting area 100 is a polygon with more than four sides, ensuring that the light-emitting area composed of multiple basic light-emitting units 10 is different from the rectangle in the prior art, and can form a quasi-circular shape that is closer to a circle. The larger the value of n, the closer the formed figure is to a circle. The outer contour of the basic light-emitting unit 10 is set to a triangle, so that multiple basic light-emitting units 10 are arranged in a circular array along the same position point to form a quasi-circular light-emitting area 100. Figure 1 The quasi-circular light-emitting area 100 drawn in the example is a hexagon, and the value of n is 6. The distance between two adjacent basic light-emitting units 10 is 10 μm to 800 μm. Preferably, the distance between two adjacent basic light-emitting units 10 is less than or equal to 500 μm, so that there is no gap between the basic light-emitting units 10, and black lines are prevented from appearing in the light-emitting panel due to the inability to light up between the basic light-emitting units 10, which affects the lighting effect of the light-emitting panel.

[0058] Furthermore, the basic light-emitting unit 10 with a triangular outer contour includes a first side a, a second side b and a third side c; the intersection of the first side a and the second side b coincides with the center point of the quasi-circular light-emitting area 100; the degree of the vertex angle formed by the first side a and the second side b is a multiple of 360 degrees; the third side c is used to form the side of the quasi-circular light-emitting area 100. Each basic light-emitting unit 10 shares the first side a and the second side b with two adjacent basic light-emitting units 10, respectively. In addition, the two basic light-emitting units 10 sharing the first side a are symmetrically arranged with the first side a as the axis of symmetry; the two basic light-emitting units 10 sharing the second side b are symmetrically arranged with the second side b as the axis of symmetry.

[0059] Based on the above embodiments, in one embodiment of the present utility model, please continue to refer to Figure 1 and Figure 2 The graphic of the quasi-circular light-emitting area 100 is composed of 2n basic light-emitting units 10 with a right-angled triangle outer contour; the first side a is the right-angled side in the right-angled triangle, and the second side b is the hypotenuse in the right-angled triangle; the third sides c of the two basic light-emitting units 10 symmetrically arranged with the first side a as the symmetry axis are located on the same side of the quasi-circular light-emitting area 100; the third sides c of the two basic light-emitting units 10 symmetrically arranged with the first side a as the symmetry axis are located on two adjacent sides of the quasi-circular light-emitting area 100.

[0060] Specifically, Figure 3 is a schematic diagram of a first intermediate graph provided by an embodiment of the utility model, with reference to Figure 3 , two basic light-emitting units 10 sharing the first side a can form a first intermediate figure. Figure 4 is a schematic diagram of a second intermediate figure provided by an embodiment of the utility model, with reference to Figure 4The two basic light-emitting units 10 sharing the second side b are symmetrically arranged with the second side b as the symmetry axis, and the two basic light-emitting units 10 sharing the first side a can form a second intermediate figure. The first intermediate figure is different from the second intermediate figure, which can further enrich the lighting effect of the light-emitting panel.

[0061] On the basis of the above embodiments, in another embodiment of the present invention, the graphic of the quasi-circular luminous area is composed of n basic light-emitting units whose outer contours are isosceles triangles (not shown); the first side is a waist side of the isosceles triangle, and the second side is another waist side of the isosceles triangle; the third side of each basic light-emitting unit corresponds to a side of the quasi-circular luminous area, and the number of sides of the quasi-circular luminous area can be further increased, so that the graphic of the quasi-circular luminous area is closer to a circle.

[0062] On the basis of the above embodiments, in one embodiment of the utility model, the light-emitting panel is an OLED light-emitting panel, wherein the sub-pixel p is an organic light-emitting structure, including an anode, an organic light-emitting layer and a cathode. The anode can be formed of various conductive materials. The organic light-emitting layer is located on the first electrode, and the organic light-emitting layer can be formed of a low molecular weight organic material or a high molecular weight organic material. The cathode is located on the organic light-emitting layer. When a voltage is applied between the anode and the cathode, the organic light-emitting layer emits visible light, thereby realizing an image that can be recognized by the user. Optionally, a hole injection layer (HIL) and a hole transport layer (HTL) may be included between the anode and the organic light-emitting layer, and at least one of an electron transport layer (ETL) and an electron injection layer (EIL) may be included between the cathode and the organic light-emitting layer. Among them, the cathodes of multiple sub-pixels p form a common cathode.

[0063] Optionally, the light-emitting panel further includes an anode connection line connected to the control unit; the anode of each sub-pixel p is connected to a corresponding anode connection line; the control unit includes a printed circuit board, and only a bonding process is required to bind each anode connection line connected to each sub-pixel p to the printed circuit board. The number of control units can be multiple, located on different sides of the light-emitting panel to prevent all sub-pixels p from being connected to the same control unit, which increases the difficulty of the bonding process. Based on the brightness adjustment of the sub-pixels p by the control unit and the combined light emission control between the sub-pixels p, the light-emitting picture formed by the light-emitting panel includes static pictures and dynamic pictures with multiple spatial dimensions.

[0064] Exemplary, reference Figures 5 to 9 Each sub-pixel emits light independently. Different lighting patterns can be formed based on lighting up different sub-pixels and adjusting the brightness values ​​of the lit sub-pixels. The formed lighting patterns have static or dynamic effects in multiple spatial dimensions. Figure 5In the example light-emitting picture, only some sub-pixels are lit to form a triangular windmill effect pattern, and a windmill rotating effect appears as the triangle keeps changing in brightness. Figure 6 In the example light-emitting picture, all sub-pixels are lit. By changing the brightness of the sub-pixels, the quasi-circular light-emitting area can be divided into several rings, and a dynamic target effect pattern can be formed when the brightness changes. Figure 7 In the example light-emitting image, the sub-pixels in the center area are lit up to form a flower effect pattern. Figure 8 The example display screen lights up multiple circles of sub-pixels, and forms a tunnel effect pattern with a sense of depth through changes in light and dark. Fig. 9 In the example luminous image, some sub-pixels are scattered and lit, forming a star-like effect pattern.

The control unit 300 being located outside the substrate 200 can be understood as the vertical projection of the control unit 300 on the plane where the substrate 200 is located is located outside the substrate 200.

Fig.12 The second control subunit 302 and the third control subunit 303 are exemplarily shown to be located at the first side t1 and the second side t2 of the substrate 200 , respectively, and both are outside the substrate 200 .

[0071] refer to Fig.13 and Fig.14, the control unit 300 includes a fourth control subunit 304, a fifth control subunit 305 and a sixth control subunit 306; the quasi-circular light-emitting area includes a middle area Q0 and a first area Q1 and a second area Q2 located on opposite sides of the middle area Q0; the fourth control subunit 304 is located at a side different from the fifth control subunit 305 and the sixth control subunit 306; wherein the fourth control subunit 304 is connected to the sub-pixel p in the middle area Q0, the fifth control subunit 305 is connected to the sub-pixel p in the first area Q1, and the sixth control subunit 306 is connected to the sub-pixel p in the second area. It can be understood that since the area of ​​the sub-pixel p located in the middle area Q0 is small, the sub-pixels p in the middle area Q0 are densely packed, so a control subunit is separately arranged at one side of the substrate 200 to connect with the sub-pixel p located in the central area, so as to facilitate the connection between the sub-pixel p in the central area and the control subunit. Among them, the sub-pixel p located on the area dividing line can be connected to the control subunit closest to it.

[0072] Please continue to refer to Fig.13 , the fifth control subunit 305 and the sixth control subunit 306 can be located at the same side of the substrate 200. The fifth control subunit 305 and the sixth control subunit 306 are arranged at the same side of the substrate 200 along the first direction, and the fourth control subunit 304 is located at a side of the substrate 200 opposite to the fifth control subunit 305, and the projection of the fourth control subunit 304 along the second direction covers the interval area between the fifth control subunit 305 and the sixth control subunit 306; wherein the first direction is perpendicular to the second direction. The length of the fourth control subunit 304 in the first direction is set to be greater than the width of the middle area Q0, which can increase the number of pins on the fourth control subunit 304 and / or the spacing between the pins, so as to further facilitate the connection with the sub-pixel p in the central area. In addition, the width of the first area Q1 and the width of the second area Q2 can be set to be greater than the width of the middle area Q0, which can reduce the number of sub-pixels P in the middle area Q0, thereby further facilitating the connection of the fourth control subunit 304 with the sub-pixel p in the central area.

[0073] Please continue to refer to Fig.14 , the fifth control subunit 305 and the sixth control subunit 306 can be located at different sides of the substrate 200, and the lengths of the fifth control subunit 305 and the sixth control subunit 306 can be increased, thereby increasing the number of pins on the fifth control subunit 305 and / or the spacing between the pins, and increasing the number of pins on the sixth control subunit 306 and / or the spacing between the pins. This can further facilitate the connection between the fifth control subunit 305 and the sub-pixel p of the first zone Q1, and the connection between the sixth control subunit 306 and the sub-pixel p of the second zone Q2. In addition, Fig.14In the structure shown, the anode connection line of the sub-pixel in the first area Q1 can extend to an entire side edge (third side edge t3) of the substrate, and then connect to the fifth control sub-unit 305, so that the spacing between the anode connection lines can be increased, and the wiring difficulty of the anode connection line of the sub-pixel in the first area Q1 can be reduced. The anode connection line of the sub-pixel in the second area Q2 can extend to an entire side edge (fourth side edge t4) of the substrate, and then connect to the sixth control sub-unit 306, so that the spacing between the anode connection lines can be increased, and the wiring difficulty of the anode connection line of the sub-pixel in the second area Q2 can be reduced.

[0074] The embodiment of the utility model also provides a light-emitting device, including the light-emitting panel described in any embodiment of the utility model. The light-emitting device can be used in vehicle lights for static electric lighting and dynamic lighting of vehicle lights. The initial pattern of the basic light-emitting unit is divided by a quasi-crystal division method to form a sub-pixel pattern, so that the overall arrangement pattern of the sub-pixels in the basic light-emitting unit has the basic properties of a quasi-crystal, thereby making the lighting effect of the light-emitting device more diversified and personalized. In addition, the patterns of the sub-pixels in two adjacent basic light-emitting units are symmetrically arranged along the same axis of symmetry, so that the arrangement of the sub-pixels in the quasi-circular light-emitting area has a regularity, which is convenient for enhancing the regularity of the lighting of the light-emitting device; in addition, the control unit independently controls each sub-pixel, so that the area where each sub-pixel is located is an independent light-emitting area, so that a variety of patterns can be formed by adjusting the brightness of the light-emitting area and designing the light-emitting combination of each light-emitting interval, and the static and dynamic effects of multiple spatial dimensions can also enrich the lighting effect of the light-emitting device. The lighting effect of the light-emitting device can be referred to Figures 5 to 9 , I will not go into details here.
