[0042] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0043] like Figures 1 to 14 As shown, the utility model provides a modular Micro LED display screen, including a display unit module 1 and a universal driving chip module 2, the display unit module 1 is provided with a plurality of display units 3 and a plurality of first communication connectors 4, the display unit 3 is electrically connected to the first communication connector 4, the universal driving chip module 2 is provided with a plurality of driving circuits and a plurality of second communication connectors 5, the driving circuit is electrically connected to the second communication connector 5, the first communication connector 4 corresponds to the second communication connector 5 one by one, the first communication connector 4 and the second communication connector 5 are adapted to each other, and the first communication connector 4 can be disconnectably electrically connected to the second communication connector 5.

[0044] In this embodiment, the display unit module 1 includes a first circuit board 6, one end face of the first circuit board 6 is electrically connected to a plurality of display units 3, and the other end face of the first circuit board 6 is arrayed with a plurality of first communication connectors 4. The display unit 3 is a single-color lamp bead or a three-color lamp bead or other light-emitting device, and the number of the display units 3 is set according to the user's requirements for the spacing between the two display units 3 and the size of the display screen. The plurality of display units 3 are arranged in an array, and in this embodiment, the display unit 3 is a three-color lamp bead.

[0045] In this embodiment, the universal driving chip module 2 includes a second circuit board 7, one end surface of the second circuit board 7 is electrically connected with a plurality of driving circuits, the driving circuit includes a plurality of electronic components 8, including at least an IC chip, a resistor, and a capacitor, and the other end surface of the second circuit board 7 is arrayed with a plurality of second communication connectors 5, the driving circuit is electrically connected to the second communication connector 5. The number of driving circuits is set according to the number of display unit modules 1 driven.

[0046] In this embodiment, the first circuit board and the second circuit board are PCB boards.

[0047] The first communication connector 4 and the second communication connector 5 can be a data interface, a plug connector, a pin header, etc., as long as they can connect signals. The first communication connector 4 and the second communication connector 5 of this embodiment use plug connectors for signal communication, which not only connects signals but also isolates the first circuit board 6 and the second circuit board 7, thereby ensuring heat dissipation.

[0048] The first communication connector 4 may also be arranged at other positions of the first circuit board 6, and the second communication connector 5 may also be arranged at other positions of the second circuit board 7. If the first communication connector 4 is arranged at other positions of the first circuit board 6 and the second communication connector 5 is arranged at other positions of the second circuit board 7, resulting in the first circuit board 6 and the second circuit board 7 being close to each other, further leading to a poor heat dissipation effect, a person skilled in the art may solve the heat dissipation problem by arranging a support between the first circuit board 6 and the second circuit board 7 to isolate the first circuit board 6 and the second circuit board 7.

[0049] The universal driver chip module 2 can be electrically connected to at least one display unit module 1 in a disconnectable manner. Multiple first communication connectors 4 can be set to light up the display unit 3 according to the electrical properties of the electronic components 8 on the display unit module 1 or the needs of the customer, wherein the multiple first communication connectors 4 are connected in series or in parallel. In this embodiment, one display unit module 1 is electrically connected to one first communication connector 4, and one universal driver chip module 2 is electrically connected to eight second communication connectors 5, that is, one universal driver chip can drive eight display unit modules 1 at the same time. The eight display unit modules 1 can be display unit modules 1 of the same specification, or they can be display unit modules 1 of different specifications, that is, lamp beads and lamp boards with different spacings can be assembled on one LED display screen.

[0050] The display screen of the utility model is detachable, and the display unit module 1 and the universal driver chip module 2 realize the connection and disconnection of the circuit through the first communication connector 4 and the second communication connector 5. Therefore, the utility model breaks the traditional mode that production and manufacturing must be based on the customer's demand for the spacing of the lamp beads. The factory only needs to continuously produce the display unit module 1 and the universal driver chip module 2, and then combine the display unit module 1 and the universal driver chip module 2 according to the needs of the customer's order to complete the display screen product, thereby improving production efficiency. When repairing or upgrading the terminal display screen product, there is no need to replace or repair the entire display screen module, only the corresponding display unit module 1 and / or the universal driver chip module 2 need to be replaced, which greatly reduces the maintenance cost and upgrade cost. In this embodiment, when it is necessary to replace the display unit module 1 with a different spacing, it is only necessary to remove the original display unit module 1 and plug the display unit module 1 with the required spacing into the universal chip module through a connector.

[0051] The display unit module 1 and the universal driver chip module 2 can be standardized to achieve standardization of the Micro LED display screen.

[0052] The display unit module 1 and the universal driver chip module 2 are produced separately. Therefore, by manufacturing display unit modules 1 and universal driver chip modules 2 of different specifications, display screens of different specifications can be assembled, which breaks the limitation of the size of the traditional Micro LED display light board and can produce Micro LED display screens of any size.

Except for special instructions in the embodiments, the specific connection relationship can bring corresponding technical effects and solve the technical problems raised by the utility model without relying on the execution of corresponding software programs.
