[0058] Please refer to Figure 1-Figure 5, a light emitting body 100 provided in an embodiment of the present invention is used for a display device. The light emitting body 100 includes at least two light emitting units 11 and a pin portion 13. Each light emitting unit 11 includes a first electrode 111 and a second electrode 113. The pin portion 13 includes a common pin 131 and at least two pixel pins 133. The common pin 131 is electrically connected to the first electrodes 111 of at least two light emitting units 11, and each pixel pin 133 is electrically connected to the second electrode 113 of each light emitting unit 11.

[0059] The above-mentioned light-emitting body 100, when arranging multiple light-emitting units 11 in series, can realize a single-layer wiring design of the light-emitting body 100, thereby reducing the process difficulty and cost, and is conducive to realizing more features such as high resolution and flexible screen.

[0060] Specifically, it can be understood that when the common pin 131 connects the first electrodes 111 of at least two light-emitting units 11, the number of pins on the light-emitting body 100 can be reduced, and the flexibility of the setting of the common pin 131 on the light-emitting body 100 can be increased, so that the common pin 131 and multiple pixel pins 133 can be set on the same side of the light-emitting body 100. This can reduce wiring crossing, facilitate wiring design, and avoid the need for vias or jumpers and multi-layer settings due to pin position issues.

[0061] It should be noted that in some implementation modes, please combine Figure 2 and Figure 3 The common pin 131 includes one, one common pin 131 is located on one side of the light-emitting body 100 along the first direction, at least two pixel pins 133 are located on the other side of the light-emitting body 100 along the first direction, each pixel pin 133 includes a first pixel pin 1331 and a second pixel pin 1333, the first pixel pin 1331 and the second pixel pin 1333 are connected to the second electrode 113 of the same light-emitting unit 11, the first pixel pin 1331 and the second pixel pin 1333 are respectively located on both sides of the light-emitting body 100 along the second direction, and are electrically connected inside the light-emitting body 100, and the first direction is perpendicular to the second direction.

[0062] That is to say, by arranging the first pixel pin 1331 and the second pixel pin 1333 at intervals on both sides of the light-emitting body 100 along the second direction, the wiring on the display device can be electrically connected to the common pin 131 corresponding to the first electrode 111 between the first pixel pin 1331 and the second pixel pin 1333 along the first direction without being short-connected to the pixel pin 133 corresponding to the second electrode 113, thereby avoiding via design and realizing single-layer wiring design.

[0063] In other embodiments, please combine Figure 4 and Figure 5The common pins 131 include two, and the two common pins 131 are respectively located on both sides of the light-emitting body 100 , and the two common pins 131 are electrically connected inside the light-emitting body 100 .

[0064] That is to say, by arranging two common pins 131 at intervals on both sides of the light-emitting body 100 along the first direction, and arranging all the pixel pins 133 in the interval between the two common pins 131, the wiring on the display device can be electrically connected along the first direction to the two common pins 131 corresponding to the first electrodes 111 located on both sides respectively, and will not be short-connected to the pixel pin 133 corresponding to the second electrode 113 located between the two common pins 131, thereby realizing a single-layer wiring design.

[0065] In addition, Figure 4 and Figure 5 In the above-described embodiment, the two common pins 131 are respectively located on both sides of the light emitting body 100 along the first direction, and the two pixel pins 133 are located between the two common pins 131 along the first direction. It can be understood that in other embodiments, the two common pins 131 may also be respectively located on both sides of the light emitting body 100 along the second direction, and the two pixel pins 133 may be located between the two common pins 131 along the second direction. The distribution direction of the plurality of common pins 131 on the light emitting body 100 and the relative positions between the pixel pins 133 and the common pins 131 in other embodiments are not limited here.

[0066] It can be understood that the light-emitting unit 11 can be used to emit light of different colors, so that the display device can display different images. 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 refers to a light-emitting unit 11 that can emit red light when it is electrically connected to the first electrode 111 and the second electrode 113. The green light-emitting unit 11 refers to a light-emitting unit 11 that can emit green light when it is electrically connected to the first electrode 111 and the second electrode 113. The blue light-emitting unit 11 refers to a light-emitting unit 11 that can emit blue light when it is electrically connected to the first electrode 111 and the second electrode 113.

[0067] Please refer to Figure 1 , Figure 6 and Figure 7 In some embodiments, the number of the light emitting units 11 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.

[0068] Further, according to the foregoing, when the number of the light emitting units 11 is two, the following combinations can be respectively provided: 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 (e.g. Figure 1 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 shown); Figure 6 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 shown); Figure 7 shown).

[0069] In addition, Figure 2 In the illustrated embodiment, the number of pixel pins 133 (i.e., the sum of the number of first pixel pins 1331 and second pixel pins 1333) is four. Figure 4 In the illustrated embodiment, the number of the pixel pins 133 is two. In other embodiments, the number of the pixel pins 133 can be selected according to specific circumstances, and can also be calibrated through actual tests.

[0070] It can be understood that in different practical 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 body 100 can be adjusted to meet the actual needs in different situations and increase the flexibility of the light-emitting body 100 in application.

[0071] Please refer to Figure 8 In some embodiments, the number of the light emitting units 11 is three. The three light emitting units 11 are respectively a red light emitting unit 11, a green light emitting unit 11 and a blue light emitting unit 11. In this way, the light emitting body 100 can emit light of more colors, so that the display device can display images with richer colors.

[0072] Specifically, please combine Figure 2 In such an embodiment, when the number of the light emitting units 11 is three, the number of the corresponding pixel pins 133 is six. Figure 4 In such an embodiment, when the number of the light-emitting units 11 is three, the number of the corresponding pixel pins 133 is four.

[0073] 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 circumstances, or calibrated according to actual tests. Specifically, in such an embodiment, the number of light emitting units 11 is four, one of which is a red light emitting unit 11, one of which is a green light emitting unit 11, and the other two are blue light emitting units 11. The embodiment is not specifically limited here.

[0074] In addition, in other embodiments, the light emitting body 100 is a rectangular body. In one embodiment, a common pin 131 is located on one side of the rectangular body close to one of the short sides, a first pixel pin 1331 of a plurality of pixel pins 133 is located on one side of one of the long sides of the rectangular body, and a second pixel pin 1333 of a plurality of pixel pins 133 is located on the other side of the other long side of the rectangular body. In another embodiment, two common pins 131 are respectively located on one side of the rectangular body close to the short side. In yet another embodiment, two common pins 131 are respectively located on two opposite sides of the same face of the rectangular body. In this way, the light emitting body 100 can be electrically connected through different two sides.

[0075] In some embodiments, the light emitting unit 11 is a light emitting diode.

[0076] Specifically, in such an implementation, please combine Figure 2 and Figure 4 , the positive electrode of the light emitting unit 11 is the first electrode 111, and the negative electrode of the light emitting unit 11 is the second electrode 113. Figure 2 In the embodiment shown, the common pin 131 is connected to the positive electrodes of all the light emitting units 11, so that all the light emitting units 11 are connected in a common anode manner. Figure 4 In the illustrated embodiment, the two common pins 131 are connected to the positive electrodes of all the light emitting units 11 at the same potential, so that all the light emitting units 11 are connected in a common anode manner.

[0077] In another embodiment, please combine Fig. 9 and Fig.10 , the cathode of the light-emitting unit 11 is the first electrode 111, and the anode of the light-emitting unit 11 is the second electrode 113. Fig. 9 In the embodiment shown, the common pin 131 is connected to the cathodes of all the light emitting units 11, so that all the light emitting units 11 are connected to each other in a common cathode manner. Fig.10In the illustrated embodiment, two common pins 131 are connected to the cathodes of all the light emitting units 11 at the same potential, so that all the light emitting units 11 are connected in a common cathode manner. In other embodiments, all the light emitting units 11 may be connected in a common anode manner or in a common cathode manner according to specific circumstances. The embodiments are not specifically limited herein.

[0078] In addition, the light-emitting unit 11 may be an OLED (Organic Light-Emitting Diode), an inorganic metal semiconductor, or an inorganic light-emitting diode.

[0079] Please refer to Figure 1 , Figure 3 , Figure 5 In some embodiments, at least two light emitting units 11 are disposed on the same side of the light emitting body 100, and the common pin 131 and at least two pixel pins 133 are disposed on the other side of the light emitting body 100. In this way, the light emitting unit 11 can be packaged.

[0080] Specifically, in the illustrated embodiment, two light-emitting units 11 are arranged in the first direction in the light-emitting body 100. When at least two light-emitting units 11 are arranged on the same side of the light-emitting body 100, and the common pin 131 and all the pixel pins 133 are arranged on the other side of the light-emitting body 100, all the light-emitting units 11, the common pin 131 and all the pixel pins 133 are packaged by the light-emitting body 100, so that the connection between each light-emitting unit 11 and the common pin 131 and the pixel pin 133 can be complete, thereby ensuring the integrity of the overall structure of the light-emitting body 100, and facilitating the subsequent processing of the light-emitting body 100 on the display device.

[0081] In addition, in other embodiments, one common pin 131 and at least two pixel pins 133 are disposed on the other side of the light emitting body 100, and may be disposed on a side adjacent to the light emitting surface of the light emitting body 100 (i.e., the side where all the light emitting units 11 are located), or may be disposed on the opposite side of the light emitting surface of the light emitting body 100. Other embodiments are not limited herein.

[0082] Please refer to Figure 1 , Figure 6-Figure 8 In some embodiments, the light emitting surface of the light emitting body 100 is rectangular. At least two light emitting units 11 are evenly spaced apart on the light emitting body 100 along the first direction.

[0083] In addition, please refer to Fig.11 In some embodiments, the light emitting surface of the light emitting body 100 is a square. At least two light emitting units 11 are evenly spaced apart on the light emitting body 100 .

[0084] In this way, the display device can display images better.

[0085] Specifically, in the illustrated embodiment, all the light emitting units 11 are evenly spaced along the first direction, so that the light emitting body 100 can emit overall uniform light, thereby enabling the display device to better display a given image. The interval between two adjacent light emitting units 11 can be determined according to specific circumstances. In one embodiment, the first direction is the length direction of the light emitting body 100.

[0086] Please refer to Figure 5 In some embodiments, along the first direction, the common pin 131 and at least two pixel pins 133 are evenly spaced and arranged on the same side of the light emitting body 100. In this way, the light emitting body 100 can be conveniently connected to the display device.

[0087] Specifically, in the illustrated embodiment, between the common pin 131 and all the pixel pins 133, every two adjacent ones are arranged at the same distance on the light emitting body 100, so as to avoid the common pin 131 and one of all the pixel pins 133 being displaced and causing poor contact at the pins. The size of the interval between the common pin 131 and all the pixel pins 133 can be determined according to the specific situation.

[0088] Please refer to Figure 11-13 In some embodiments, the number of common pins 131 is two. The number of light-emitting units 11 is three. The number of pixel pins 133 is three. Along the first direction, two common pins 131 and one pixel pin 133 are evenly spaced apart on one side of the same side of the light-emitting body 100, and the other two pixel pins 133 are evenly spaced apart on the other side of the same side of the light-emitting body 100. In this way, the light-emitting body 100 can be conveniently connected to the display device.

[0089] Specifically, in the illustrated embodiment, two common pins 131 and one of the pixel pins 133 are evenly spaced on one side of the same side of the light emitting body 100, and the other two pixel pins 133 are evenly spaced on the other side of the same side of the light emitting body 100, which can avoid the situation where one of the two common pins 131 and all the pixel pins 133 is shifted and causes poor contact at the pins. The size of the interval formed by the two common pins 131 and one of the pixel pins 133, and the size of the interval formed by the other two pixel pins 133 can be the same or different, which can be determined according to the specific situation.

[0090] Please refer to Fig.12 and Fig.13In some embodiments, two common pins 131 and one pixel pin 133 are arranged on the same side of the light emitting body 100, and the pixel pin 133 is located between the two common pins 131. In this way, the wiring layout on the display device 200 can be simplified to avoid short circuits.

[0091] Specifically, Fig.13 : represents a partial circuit structure on the display device 200 for electrically connecting the light emitting body 100. The display device 200 includes a first pad 211 and a second pad 213. There are two first pads 211, and the two first pads 211 are used to electrically connect the two common pins 131 of the light emitting body 100, respectively. There are multiple second pads 213, and one second pad 213 is arranged between the two first pads 21 and is used to electrically connect one pixel pin 133 of the light emitting body 100. It can be understood that since the pixel pin 133 located between the two common pins 131 and the two common pins 131 are staggered, the first pad 211 and the second pad 213 of the circuit structure on the display device 200 are also staggered, so that the wiring layout on the display device 200 can be facilitated to avoid the occurrence of wiring short circuit.

[0092] Please refer to Figure 14-16 In an embodiment of the present invention, a display device 200 is provided, comprising a circuit board 21 and a light emitting body 100 of any of the above embodiments. There are multiple light emitting bodies 100, and the multiple light emitting bodies 100 are arranged in a matrix along a first direction and a second direction on the circuit board 21.
