[0002] In the related art, the wiring design of the display screen of Mini LED (or Micro LED) is generally a multi-layer wiring design. As the screen resolution increases, the wiring becomes more and more complex, resulting in an increase in the number of vias, thereby increasing the process cost and making it difficult to meet the wiring requirements of multi-layer flexible materials and the like. Summary of the Invention

[0003] Embodiments of the present invention provide a light-emitting packaging structure and a display screen.

[0004] A light-emitting packaging structure provided by an embodiment of the present invention is used for a display screen. The light-emitting packaging structure includes:

[0005] N pixel units, where N is a natural number greater than 1. Each pixel unit includes:

[0006] At least two light-emitting units arranged at intervals, and each light-emitting unit includes a first electrode and a second electrode; and

[0007] A pin portion, the pin portion includes two first common pins, two second common pins and M groups of pixel pins. The two first common pins are electrically connected to the first electrodes of at least two light-emitting units of a part of the pixel units, the two second common pins are electrically connected to the first electrodes of at least two light-emitting units of the remaining pixel units, and each group of pixel pins includes a plurality of pixel pins corresponding to the number of light-emitting units. Each pixel pin is electrically connected to the second electrode of each light-emitting unit. Wherein, when N is an even number, M = N / 2; when N is an odd number, M = (N + 1) / 2;

[0008] Wherein,

[0009] One of the first common pins and one of the second common pins are located on the same side of the light-emitting packaging structure, and the other first common pin and the other second common pin are located on the other same side of the light-emitting packaging structure. The two first common pins are electrically connected inside the light-emitting packaging structure, and the two second common pins are electrically connected inside the light-emitting packaging structure.

[0010] In the case of arranging a plurality of pixel units in a straight-line arrangement, the above light-emitting packaging structure can achieve a single-layer wiring design of the light-emitting packaging structure, thereby reducing the process difficulty and cost, and being beneficial to realizing a display screen with more features (such as high resolution, flexible screen, etc.).

[0011] In some embodiments, the number of light-emitting units included in each of the pixel units is two, the number of each group of pixel pins is two, and the two light-emitting units are two of a red light-emitting unit, a green light-emitting unit, and a blue light-emitting unit. In this way, the flexibility of configuring the light-emitting units can be increased.

[0012] In some embodiments, the number of light-emitting units included in each of the pixel units is three, the number of each group of pixel pins is three, and the three light-emitting units are respectively a red light-emitting unit, a green light-emitting unit, and a blue light-emitting unit. In this way, the light-emitting encapsulation structure can emit more colors of light, so that the display screen can display images with richer colors.

[0013] In some embodiments, the light-emitting encapsulation structure is a rectangular body.

[0014] One of the first common pins and one of the second common pins are located on one of the opposite sides of the same surface of the rectangular body, and the other first common pin and the other second common pin are located on the other of the opposite sides of the same surface of the rectangular body. In this way, the light-emitting encapsulation structure can be electrically connected through different two sides.

[0015] In some embodiments, the two first common pins and the two second common pins are respectively located at the four corners of the rectangular body. In this way, the specific positions of the two first common pins and the two second common pins can be simply determined.

[0016] In some embodiments, the N pixel units are arranged in the light-emitting encapsulation structure along the length direction and / or the width direction of the light-emitting encapsulation structure. The N pixel units are arranged on the same side surface of the light-emitting encapsulation structure, and the two first common pins, the two second common pins, and the M groups of pixel pins are arranged on the other side of the light-emitting encapsulation structure. In this way, the encapsulation of the light-emitting units can be realized.

[0017] In some embodiments, along the length direction and / or the width direction of the light-emitting encapsulation structure, the N pixel units are evenly spaced in the light-emitting encapsulation structure. In this way, the display screen can display images better.

[0018] In some embodiments, the two first common pins and the two second common pins are located around the M groups of pixel pins. In this way, it is convenient for the light-emitting encapsulation structure to be connected to the display screen.

[0019] A display screen provided by an embodiment of the present invention, the display screen includes:

[0020] A circuit board; and

[0021] The light-emitting encapsulation structure described in any of the above embodiments, wherein the number of the light-emitting encapsulation structures is multiple, and the multiple light-emitting encapsulation structures are arranged in a matrix along a first direction and a second direction on the circuit board. The first direction is the length direction of the circuit board, and the first direction is perpendicular to the second direction.

[0022] For the above display screen, when multiple pixel units are arranged in a straight line, a single-layer wiring design of the light-emitting encapsulation structure can be realized, thereby reducing the process difficulty and cost, and facilitating the realization of a display screen with more features (such as high resolution, flexible screen, etc.).

[0023] In some embodiments, among two adjacent light-emitting encapsulation structures arranged along the first direction, the first common pin and the second common pin of one of the light-emitting encapsulation structures are respectively connected to the first common pin and the second common pin of the other light-emitting encapsulation structure;

[0024] Among two adjacent light-emitting encapsulation structures arranged along the second direction, the pixel pins of the light-emitting units of one of the light-emitting encapsulation structures are sequentially connected to the pixel pins of the corresponding light-emitting units of the other light-emitting encapsulation structure one by one. In this way, the number of wirings on the circuit board can be simplified, and at the same time, it is convenient to control all the light-emitting encapsulation structures to emit light.

[0047] Please refer to Figures 1-4 , a light-emitting package structure 100 provided by an embodiment of the present invention is used for a display screen. The light-emitting package structure 100 includes N pixel units 10 and a pin portion 13. Where N is a natural number greater than 1. Each pixel unit 10 includes at least two light-emitting units 11 arranged at intervals, and each light-emitting unit 11 includes a first electrode 111 and a second electrode 113. The pin portion 13 includes two first common pins 131, two second common pins 132, and M groups of pixel pins 133. The two first common pins 131 are electrically connected to the first electrodes 111 of at least two light-emitting units 11 of a part of the pixel units 10, the two second common pins 132 are electrically connected to the first electrodes 111 of at least two light-emitting units 11 of the remaining pixel units 10, and each pixel pin 133 is electrically connected to the second electrode 113 of each light-emitting unit 11. When N is an even number, M = N / 2; when N is an odd number, M = (N + 1) / 2. Wherein, one first common pin 131 and one second common pin 132 are located on the same side of the light-emitting package structure 100, the two first common pins 131 are electrically connected inside the light-emitting package structure 100, and the two second common pins 132 are electrically connected inside the light-emitting package structure 100.

[0048] For the above-mentioned light-emitting encapsulation structure 100, when multiple pixel units 10 are arranged regularly, a single-layer wiring design of the light-emitting encapsulation structure 100 can be achieved, thereby reducing the process difficulty and cost, avoiding the defects of complex wiring between multiple pixels in the past, such as the need for via bridging or multi-layer wiring, and being conducive to realizing a display screen with more features (such as high resolution, flexible screen, etc.).

[0049] It can be understood that when two first common pins 131 are connected to the first electrodes 111 of a part of the pixel units 10 and the second common pins 132 are connected to the first electrodes 111 of the remaining pixel units 10, the number of pins on the light-emitting encapsulation structure 100 can be reduced, and the flexibility of setting the first common pins 131 and the second common pins 132 on the light-emitting encapsulation structure 100 can be increased. Thus, the first common pins 131, the second common pins 132, and multiple pixel pins 133 can be arranged on the same side of the light-emitting encapsulation structure 100, which can reduce wiring crossovers, facilitate wiring design, and avoid the situation of requiring vias or jumpers and setting them into multiple layers due to pin position problems.

[0050] Specifically, in the Figure 1 and Figure 2 shown embodiments, the number of pixel units 10 is two (i.e., N is an even number), the number of light-emitting units 11 in each pixel unit 10 is three, the number of pixel pins 133 is one group, and the number of pins in one group of pixel pins 133 is three. The three pixel pins 133 in the above-mentioned one group are sequentially connected to the three light-emitting units 11 in one pixel unit 10 one by one, and are sequentially connected to the three light-emitting units 11 in the other pixel unit 10 one by one. In the Figure 3 and Figure 4 shown embodiments, the number of pixel units 10 is three (i.e., N is an odd number), the number of light-emitting units 11 in each pixel unit 10 is three, the number of pixel pins 133 is two groups, and the number of pins in each group of pixel pins 133 is three. The three pixel pins 133 in one group are sequentially connected to the three light-emitting units 11 in one of the pixel units 10 one by one, and are sequentially connected to the three light-emitting units 11 in another pixel unit 10 one by one, and the three pixel pins 133 in the other group are sequentially connected to the three light-emitting units 11 in another pixel unit 10 one by one. Please refer to Figure 5 again. In the Figure 5 shown embodiments, the number of light-emitting units 11 in each pixel unit 10 can be four, and the specific principle is the same as that of the above-mentioned embodiments. It can be understood that in other embodiments, the number of light-emitting units 11 in each pixel unit 10 can be more than three.

[0051] In addition, in the illustrated embodiment, the number of pins in a set of pixel pins 133 is the same as the number of light-emitting units 11 included in each pixel unit 10. In other embodiments, the number of pins in a set of pixel pins 133 can be set to be different from the number of light-emitting units 11 included in each pixel unit 10 according to specific circumstances. The specific principle can refer to the specific principle of the embodiment.

[0052] In addition, in other embodiments, one first common pin 131 and one second common pin 132 are located on the same side of the light-emitting package structure 100, and the other first common pin 131 and the other second common pin 132 are located on the other same side of the light-emitting package structure 100. They can be located on both sides adjacent to the light-emitting surface of the light-emitting package structure 100, or on both sides opposite to the light-emitting surface of the light-emitting package structure 100, or one side is located adjacent to the light-emitting surface of the light-emitting package structure 100 and the other side is located opposite to the light-emitting surface of the light-emitting package structure 100, etc. The light-emitting surface refers to the side where all pixel units 10 are located on the light-emitting package structure 100. Other embodiments are not limited herein.

[0053] It can be understood that the light-emitting unit 11 can be used to emit light of different colors, so that different images can be displayed on the display screen. In some embodiments, the light-emitting unit 11 can be one of a red light-emitting unit 11, a green light-emitting unit 11, and a blue light-emitting unit 11. Specifically, the red light-emitting unit 11 means that when the light-emitting unit 11 is electrically connected through the first electrode 111 and the second electrode 113, the light-emitting unit 11 can be energized to emit red light. The green light-emitting unit 11 means that when the light-emitting unit 11 is electrically connected through the first electrode 111 and the second electrode 113, the light-emitting unit 11 can be energized to emit green light. The blue light-emitting unit 11 means that when the light-emitting unit 11 is electrically connected through the first electrode 111 and the second electrode 113, the light-emitting unit 11 can be energized to emit blue light.

[0054] Please refer to Figures 6-8 , in some embodiments, the number of light-emitting units 11 included in each pixel unit 10 is two. The number of each set of pixel pins 133 is two. The two light-emitting units 11 are two of the red light-emitting unit 11, the green light-emitting unit 11, and the blue light-emitting unit 11. In this way, the flexibility of configuring the light-emitting unit 11 can be increased.

[0055] Furthermore, according to the foregoing, when the number of light-emitting units 11 is two, the following combinations can be respectively: one light-emitting unit 11 is a red light-emitting unit 11, and the other light-emitting unit 11 is a green light-emitting unit 11 (such asFigure 6 As shown); one light-emitting unit 11 is a blue light-emitting unit 11, and the other light-emitting unit 11 is a red light-emitting unit 11 (as Figure 7 shown); one light-emitting unit 11 is a green light-emitting unit 11, and the other light-emitting unit 11 is a blue light-emitting unit 11 (as Figure 8 shown).

[0056] It can be understood that in different actual situations, light-emitting units 11 of different colors can be selected, and the relative positions of the two light-emitting units 11 on the light-emitting package structure 100 can be adjusted, so as to meet the actual needs in different situations and increase the flexibility of the light-emitting package structure 100 during application.

[0057] Please refer to Figure 9 , in some embodiments, the number of light-emitting units 11 included in each pixel unit 10 is three. The number of each group of pixel pins 133 is three. The three light-emitting units 11 are a red light-emitting unit 11, a green light-emitting unit 11, and a blue light-emitting unit 11 respectively. In this way, the light-emitting package structure 100 can emit more colors of light, so that the display screen can display images with richer colors.

[0058] In addition, it can be understood that in other embodiments, the number of light-emitting units 11 can be four or more, and the number of light-emitting units 11 of different colors can be selected according to specific situations or calibrated according to actual tests. Specifically, in such an embodiment, the number of light-emitting units 11 is four, one of the light-emitting units 11 is a red light-emitting unit 11, one of the light-emitting units 11 is a green light-emitting unit 11, and the other two are blue light-emitting units 11. The embodiments are not specifically limited herein.

[0059] In addition, in other embodiments, the light-emitting package structure 100 is a rectangular body. In one embodiment, one first common pin 131 and one second common pin 132 are located on one of the opposite sides of the rectangular body, and the other first common pin 131 and the other second common pin 132 are located on the other of the opposite sides of the rectangular body. In this way, the light-emitting package structure 100 can form electrical connections through different sides. In one embodiment, the two first common pins 131 and the two second common pins 132 are respectively located at the four corners of the rectangular body, so that the specific positions of the two first common pins 131 and the two second common pins 132 can be simply determined.

[0060] In some embodiments, the light-emitting unit 11 is a light-emitting diode. Specifically, in such an embodiment, please combine Figure 2 and Figure 4, the negative electrode of the light-emitting unit 11 is the first electrode 111, and the positive electrode of the light-emitting unit 11 is the second electrode 113. All the light-emitting units 11 connected to the first common pin 131 through the first electrode 111 are interconnected in a common cathode manner, and all the light-emitting units 11 connected to the second common pin 132 through the first electrode 111 are interconnected in a common cathode manner. It can be understood that in other embodiments, the first electrode 111 of the light-emitting unit 11 can be the positive electrode, and the second electrode 113 of the light-emitting unit 11 can be the negative electrode. It can be selected according to specific circumstances to connect multiple light-emitting units 11 in a common anode manner or in a common cathode manner. The embodiments are not specifically limited herein.

[0061] In addition, the light-emitting unit 11 can be an OLED (Organic Light-Emitting Diode), an inorganic metal semiconductor, or an inorganic light-emitting diode.

[0062] Please refer to Figure 1 and Figure 3 , in some embodiments, N pixel units 10 are arranged in the light-emitting package structure 100 along the length direction or the width direction of the light-emitting package structure 100. The N pixel units 10 are arranged on the same side of the light-emitting package structure 100, and the two first common pins 131, the two second common pins 133, and the M groups of pixel pins 133 are arranged on the other side of the light-emitting package structure 100. In this way, the light-emitting unit 11 can be encapsulated.

[0063] Specifically, in the illustrated embodiment, when the N pixel units 10 are arranged on the same side of the light-emitting package structure 100, one first common pin 131 and one second common pin 132 are arranged on one side of the light-emitting package structure 100, and another first common pin 131 and another second common pin 132 are arranged on the other side of the light-emitting package structure 100, all the pixel units 10, all the first common pins 131, all the second common pins 132, and all the pixel pins 133 are encapsulated through the light-emitting package structure 100, so that the wiring between each pixel unit 10 and the first common pin 131, the second common pin 132, and the corresponding pixel pin 133 can be complete, and further ensure the integrity of the overall structure of the light-emitting package structure 100, which is convenient for subsequent processing of the light-emitting package structure 100 on the display screen.

[0064] In addition, in other embodiments, when the number of pixel units 10 is multiple, all the pixel units 10 can be arranged in the light-emitting package structure 100 in an array form along the length direction and the width direction of the light-emitting package structure 100.

[0065] Please refer to Figure 1 andFigure 9 , in some embodiments, along the length direction of the light-emitting package structure 100, N pixel units 10 are evenly spaced and arranged on the light-emitting package structure 100. In this way, the display screen can display images better.

[0066] Specifically, in the illustrated embodiment, all the pixel units 10 are evenly spaced and arranged along the length direction of the light-emitting package structure 100, which can make the light-emitting package structure 100 emit overall symmetrical light, and further enable the display screen to display the established image better. The interval size between two adjacent pixel units 10 can be determined according to specific circumstances. In addition, in other embodiments, N pixel units 10 can be evenly spaced and arranged on the light-emitting package structure 100 along the width direction of the light-emitting package structure 100, or can be evenly spaced and arranged on the light-emitting package structure 100 along both the length direction and the width direction of the light-emitting package structure 100. There is no specific limitation here.

[0067] Please refer to Figure 10 , in some embodiments, two first common pins 131 and two second common pins 132 are located around M groups of pixel pins 133. In this way, it is convenient to connect the light-emitting package structure 100 to the display screen.

[0068] Specifically, in the illustrated embodiment, two first common pins 131 and two second common pins 132 are located around M groups of pixel pins 133, which can ensure that the two first common pins 131 and the two second common pins 132 are spaced from all the pixel pins 133, so as to avoid the situation of poor contact at the pins caused by the displacement of one of the two first common pins 131, the two second common pins 132 and all the pixel pins 133. The interval size between the two first common pins 131, the two second common pins 132 and all the pixel pins 133 can be determined according to specific circumstances.

[0069] Please refer to Figure 10 and Figure 11 , a display screen 200 provided by an embodiment of the present invention includes a circuit board 21 and the light-emitting package structure 100 of any one of the above embodiments. The number of the light-emitting package structures 100 is multiple, and the multiple light-emitting package structures 100 are arranged in a matrix along a first direction and a second direction on the circuit board 21. The first direction is the length direction of the circuit board 21. The first direction is perpendicular to the second direction.

[0070] For the above display screen 200, in the case of arranging multiple pixel units 10 in a straight-line arrangement, a single-layer wiring design of the light-emitting package structure 100 can be realized, thereby reducing the process difficulty and cost, and being beneficial to realizing a display screen 200 with more features (such as high resolution, flexible screen, etc.).

[0071] It can be understood that in the case where multiple light-emitting packaging structures 100 are arranged in a matrix on the circuit board 21, the power on and off of the pixel units 10 of all the light-emitting packaging structures 100 are controlled so that each light-emitting packaging structure 100 emits colored light in a predetermined manner, thereby enabling the display screen 200 to display a predetermined image.

[0072] In Figure 2 、 Figure 10 and Figure 11 In the embodiment shown, four first pads 211 and six second pads 213 are provided at positions on the circuit board 21 corresponding to the light-emitting packaging structures 100. The four first pads 211 are respectively used to correspondingly connect two first common pins 131 and two second common pins 132 of the light-emitting packaging structure 100, and the six second pads 213 are used to sequentially connect all the pixel pins 133 of the light-emitting packaging structure 100. It can be understood that by correspondingly connecting all the pins to the pads on the circuit board 21, the electrical connection between the light-emitting packaging structure 100 and the wiring on the circuit board 21 can be achieved.

[0073] In addition, the number of pixel units 10 in the light-emitting packaging structure 100, the number of light-emitting units 11 in the pixel unit 10, and pixels of different colors can be determined according to specific circumstances. In one embodiment, the number of light-emitting units 11 is two. In another embodiment, the number of light-emitting units 11 is eight.

[0074] Please refer to Figure 11 , in some embodiments, in two adjacent light-emitting packaging structures 100 arranged along the first direction, the first common pin 131 and the second common pin 132 of one of the light-emitting packaging structures 100 are respectively connected to the first common pin 131 and the second common pin 132 of the other light-emitting packaging structure 100. In two adjacent light-emitting packaging structures 100 arranged along the second direction, the pixel pins 133 of the light-emitting units 11 of one of the light-emitting packaging structures 100 are sequentially connected to the corresponding pixel pins 133 of the light-emitting units 11 of the other light-emitting packaging structure 100 one by one. In this way, the number of wirings on the circuit board 21 can be simplified, and at the same time, it is convenient to control all the light-emitting packaging structures 100 to be lit.

[0075] Specifically, in Figure 11 In the embodiment shown, along the first direction, the four first pads 211 of two adjacent corresponding light-emitting packaging structures 100 are sequentially connected one by one. Along the second direction, the multiple second pads 213 of two adjacent corresponding light-emitting packaging structures 100 are sequentially connected one by one.
