A programmable light strip is an auxiliary tool in scenarios such as simulation sand table displays and teaching principle simulations, which can simulate light sources and highlight key areas in a simulation sand table display, or simulate dynamic processes such as current flow and energy transfer in a teaching principle simulation.

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0023] As Figures 1 to 3 shown, the embodiment of the present application provides a display module 1 that can be directly connected in series with a programming light strip, including: a main control unit 11, a display screen 12, a first communication interface 13, a second communication interface 14, and a power supply unit 15.

[0024] The main control unit 11 is electrically connected to the display screen 12, the first communication interface 13, the second communication interface 14, and the power supply unit 15 respectively.

[0025] The first communication interface 13 and the second communication interface 14 are respectively used to be connected in series with a programming light strip 2.

[0026] Specifically, the lamp beads 21 in the programming light strip 2 adopt common models, including WS2812B, WS2812S, WS2815, GS8208, UCS1903, MT1815, TM1913, TM1914A, etc. In this embodiment, the lamp beads 21 in the programming light strip 2 adopt WS2812S.

[0027] In this embodiment, each of the lamp beads 21 in the programming light strip 2 is connected through VDD, VSS, DI, and DO pins, and the first communication interface 13 and the programming light strip 2, as well as the second communication interface 14 and the programming light strip 2, are also connected through VDD, VSS, DI, and DO pins.

[0028] Exemplarily, the first communication interface 13 and the second communication interface 14 both adopt serial communication interfaces.

[0029] Specifically, in this embodiment, the serial communication interfaces adopted by the first communication interface 13 and the second communication interface 14 both adopt the serial protocol of general I / O to simulate the light strip.

[0030] Exemplarily, the power supply unit 15 is used to be electrically connected to the power supply of the programming light strip 2.

[0031] Specifically, in this embodiment, the power supply unit 15 is used to convert the power supply voltage of the programming light strip 2 into the voltage required by the display module 1, and an existing on-board voltage conversion circuit can be used.

[0032] Exemplarily, the main control unit 11 adopts an integrated circuit chip.

[0033] Specifically, in this embodiment, the main control unit 11 adopts an MCU single-chip microcomputer in an integrated circuit chip.

[0034] Exemplarily, the main control unit 11, the first communication interface 13, the second communication interface 14, and the power supply unit 15 are all fixedly arranged on the back surface of the display screen 12.

[0035] Specifically, as Figure 2 and Figure 3 shown, by fixedly arranging the main control unit 11, the first communication interface 13, the second communication interface 14, and the power supply unit 15 on the back surface of the display screen 12, the structure of the display module 1 becomes more compact, and interference with the display of the display screen 12 is avoided.

[0036] Specifically, in this embodiment, the number of display modules 1 is one. In other possible embodiments, two or more display modules 1 can also be set, and they only need to be connected in series between the programming light strips 2.

[0037] Exemplarily, the number of displayable states of the display screen 12 does not exceed the maximum number of displayable states of each lamp bead 21 of the programming light strip 2.

[0038] Specifically, in this embodiment, each lamp bead 21 of the programming light strip 2 can display 24-bit colors, corresponding to 16,777,216 states (i.e., 2 to the 24th power). Correspondingly, the display screen 12 can also receive 16,777,216 different control instructions, and each control instruction corresponds to a displayable state of the display screen 12.

[0039] Specifically, the main control unit 11 stores a preset control instruction set.

[0040] Specifically, the number of control instructions in the preset control instruction set does not exceed the maximum number of displayable states of each lamp bead 21 of the programming light strip 2.

[0041] Specifically, in this embodiment, the number of control instructions in the control instruction set stored by the main control unit 11 does not exceed 16,777,216.

[0042] Specifically, in this embodiment, the working principle of the display module 1 is as follows: The display module 1 is connected in series between the programming light strips 2 through the first communication interface 13 and the second communication interface 14. The power supply unit 15 converts the power supply voltage of the programming light strips 2 into the voltage required by the display module 1. Since the serial communication interfaces adopted by the first communication interface 13 and the second communication interface 14 both use general-purpose I / O to simulate the serial protocol of the light strips, the display module 1 can be controlled through the interface protocol of the programming light strips 2. It is equivalent to regarding the entire display module 1 as a lamp bead 21 in the programming light strips 2. When programming the software of the programming light strips 2, the control signal for controlling the lamp bead 21 can be corresponded to the control instruction in the control instruction set stored in the main control unit 11, so as to realize the control of the display module 1 using the communication line of the programming light strips 2.

[0043] Exemplarily, the main control unit 11 is provided with a read-write interface.

[0044] Specifically, by setting the read-write interface, the control instruction set stored in the main control unit 11 can be read and written, which improves the editability of the control instruction set. In this embodiment, the read-write interface adopts a USB interface.

[0045] In this embodiment, the main control unit 11, the display screen 12, the first communication interface 13, the second communication interface 14, and the power supply unit 15 all adopt general hardware technologies and software technologies. Regarding the control of the display module 1 through the interface protocol of the programming light strips 2, only the existing programming for controlling the lamp beads 21 in the programming light strips 2 needs to be adopted. The correspondence between the control signal for controlling the lamp beads 21 and the control instruction in the control instruction set stored in the main control unit 11 is realized through the serial protocol of the general-purpose I / O of the serial communication interfaces adopted by the first communication interface 13 and the second communication interface 14. Therefore, it does not involve improvements in software or algorithms.

[0046] In the embodiment of the present application, the display module 1 is connected in series between the programming light strips 2 through the communication interface, which simplifies the wiring of the display module 1 and the programming light strips 2, and reduces the wiring difficulty and cost. At the same time, through the structure of connecting the display module 1 in series between the programming light strips 2, the power supply line and communication line of the programming light strips 2 can be used to supply power and control the display module 1, and there is no need to control the display module 1 and the programming light strips 2 separately, which improves the operation convenience of the display module 1.

Therefore, the appended claims are intended to be construed to include the preferred embodiments as well as all changes and modifications falling within the scope of the present application.

[0048] Obviously, those skilled in the art can make various changes and modifications to this application without departing from the spirit and scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalent technologies, this application is also intended to cover these changes and modifications.
