[0038] Embodiments:

[0039] Referring to Figure 4 , the embodiment provides a light-emitting panel, which comprises at least two light-emitting units 1 and a first circuit board 2. The light-emitting unit 1 is small in size, and thus is generally soldered on the first circuit board 2 to realize electrical connection between the light-emitting unit 1 and the first circuit board 2 under the condition of existing process basis. The first circuit board 2 can control the light-emitting state and light-emitting color of each light-emitting unit 1 respectively, so as to allow the light-emitting panel to generate a specific pattern, and each light-emitting unit 1 can be regarded as a pixel point.

[0040] Referring to Figures 4-5 , the light-emitting unit comprises a substrate (not shown in the figure), a plurality of visible light-emitting chips 11 and a plurality of invisible light-emitting chips 12, and the visible light-emitting chips 11 and the invisible light-emitting chips 12 are both arranged on the substrate.

[0041] Generally, the visible light-emitting chip 11 is at least three, and at least one of the visible light-emitting chips 11 can emit red light, at least one of the visible light-emitting chips 11 can emit blue light, and at least one of the visible light-emitting chips 11 can emit green light. On this basis, by adjusting the light-emitting power of each visible light-emitting chip 11, the light-emitting unit 1 can emit visible light of a specific color to meet the function of the light-emitting unit 1 as a pixel point. The light emitted by the invisible light-emitting chip 12 is invisible light, such as ultraviolet light or infrared light, which does not affect the visual effect of visible light.

[0042] The embodiment takes the case that the invisible light-emitting chip 12 emits infrared light as an example. The entire surface of the first circuit board 2 is distributed with a large number of light-emitting units 1, and each light-emitting unit 1 can emit infrared light, thereby forming an infrared light film on the surface of the light-emitting panel. When a user touches the light-emitting panel, the infrared light film will be blocked, and accordingly, by identifying the change of the infrared light film, the light-emitting panel that the user is currently touching can be locked, and then the corresponding light-emitting panel is controlled to realize the touch function.

[0043] In other embodiments, the invisible light-emitting chip 12 can emit ultraviolet light, and the specific working principle is the same as that of the embodiment, which will not be described here.

[0044] In the embodiment, the visible light emitting chip 11 and the invisible light emitting chip 12 are both located on the front surface of the substrate, so that the substrate does not shield the infrared light.

[0045] Referring to Figures 6-8 , the back surface of the substrate is provided with a first pin 13, a second pin 14 and a third pin 15. The number of the first pins 13 matches the number of the visible light emitting chips 11 to form a one-to-one correspondence relationship, and the first pins 13 are electrically connected to the anodes of the corresponding visible light emitting chips 11. The number of the second pins 14 matches the number of the invisible light emitting chips 12 to form a one-to-one correspondence relationship, and the second pins 14 are electrically connected to the anodes of the corresponding invisible light emitting chips 12. The cathodes of all the visible light emitting chips 11 and the cathodes of all the invisible light emitting chips 12 are electrically connected to the third pin 15, and the third pin 15 is used for grounding.

[0046] In addition, the light emitting unit 1 further comprises a transparent packaging shell 16, and the substrate, the visible light emitting chip 11 and the invisible light emitting chip 12 are all located in the transparent packaging shell 16. The transparent packaging shell 16 can allow the visible light and the invisible light emitted by the visible light emitting chip 11 and the invisible light emitting chip 12 to be transmitted. The first pin 13, the second pin 14 and the third pin 15 are all at least partially located outside the transparent packaging shell 16, so as to allow the first pin 13, the second pin 14 and the third pin 15 to be soldered to the first circuit board 2. Thus, the visible light emitting chip 11 and the invisible light emitting chip 12 can be electrically connected to the first circuit board 2 and controlled by the first circuit board 2.

[0047] Referring to Figure 2 , the embodiment further provides a light emitting assembly, which comprises the housing 3, a second circuit board (not shown in the figure) and at least two light emitting panels. The second circuit board is arranged in the housing 3, and the first circuit board 2 is electrically connected to the second circuit board. The second circuit board can control the first circuit board 2 in different light emitting panels respectively.

[0048] In order to facilitate the arrangement of the light emitting panel on the housing 3, the first coupling device is arranged on the first circuit board 2, the second coupling device is arranged on the second circuit board, and the first coupling device and the second coupling device are inserted and matched. When the first coupling device and the second coupling device are coupled, the light emitting panel is also magnetically attracted to the housing 3, so as to increase the connection stability of the first coupling device and the second coupling device.

[0049] Referring to Figure 1 and Figure 2 , the embodiment additionally provides a display screen, which comprises at least two light emitting assemblies, and the housings 3 are spliced and matched. By increasing or decreasing the number of the light emitting assemblies, the size of the display screen can be adjusted.

[0050] Further preferably, the edge of the display screen is provided with a wrapping edge 7 to increase the splicing strength between the housings 3.

[0051] The embodiment also provides a touch LED integrated machine, comprising a third circuit board 4, a detection camera 5, a main control beam 6 and the display screen.

[0052] Referring to Figure 1 and Figure 2 , the main control beam 6 is arranged at the bottom edge of the display screen, the third circuit board 4 is located in the main control beam 6, and all the second circuit boards are electrically connected to the third circuit board 4. The detection camera 5 is arranged at the end of the main control beam 6 to be electrically connected to the third circuit board 4. In the embodiment, the number of the detection camera 5 is two, which are respectively located at the two ends of the main control beam 6.

[0053] Referring to Figure 3 , the field of view of the detection camera 5 is 90°, which can cover the surface of the entire display screen, so as to detect the invisible light emitted by all the invisible light emitting chips 12. When the user is performing the touch operation, the detection camera 5 can recognize the light emitting plate that is currently being touched by detecting the shielding state of the infrared light, so as to allow the third circuit board 4 to control the corresponding light emitting plate to realize the touch function.

[0054] The technical features of the above embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered that it is within the scope of the present application.

It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
