[0028] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present application.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Example 1

[0032] As shown in Figures 1 to 3, the energy-saving display module of the present application is schematically shown, including a display pad and multiple display components 21. The multiple display components 21 are arranged in parallel, and the colors displayed by the multiple display components 21 are different. The display pad is used to provide a circuit loop for the display component 21.

[0033] The display assembly 21 includes a plurality of display components 211 connected in series, and the display pad is connected to the display component 211 located at the cathode end or at the anode end. When the display component 211 located at the cathode end is connected to the display pad, the plurality of display components 21 are driven by a common cathode, and when the display component 211 located at the anode end is connected to the display pad, the plurality of display components 21 are driven by a common anode. Since the plurality of display components 211 are connected in series, the voltage of the entire display assembly 21 increases, and the current passing through the display component 211 decreases, thereby reducing the heat generated by the display component 211 and the power consumption of the entire display assembly 21. At the same time, since the power consumption of the display component 21 is reduced, the size of the display component 21 can also be appropriately reduced, and the optimal current density is correspondingly smaller. Therefore, based on the above structure, the display component 21 is easier to reach its optimal current density. Preferably, the display component 211 is a Mini-LED light-emitting element or a Micro-LED light-emitting element. 1 , two display components 211 for displaying red light and connected in series are denoted as D1 , two display components 211 for displaying green light and connected in series are denoted as D2 , and two display components 211 for displaying blue light and connected in series are denoted as D3 .

[0034] The number of display components 211 in some display assemblies 21 is greater than the number of display components 211 in the remaining display assemblies 21, or the number of display components 211 in all display assemblies 21 is the same. To simplify the production process and reduce costs, the number of display components 211 in all display assemblies 21 can be the same. However, in the RGB lighting configuration, the red brightness ratio is insufficient, so the number of display components 211 in the display assemblies 21 emitting red light needs to be increased.

[0035] In this embodiment, the number of display components 211 of all display assemblies 21 is preferably the same.

[0036] Furthermore, the energy-saving display module also includes a circuit board 10, which is provided with display pads and multiple display modules 20 arranged in a matrix. The display modules 20 include multiple display components 21. As can be seen, the multiple display modules 20 arranged in a matrix on the circuit board 10 each serve as a pixel, and the multiple display components 21 in each display module 20 display different colors. Brightness adjustment between the multiple display components 21 enables a single display module 20 to display a richer color. Preferably, the multiple display components 21 are all located on the same horizontal plane.

[0037] In addition, a display driver device is provided on the circuit board 10, and the display driver device is electrically connected to the display component 211. Of course, there are multiple display driver devices, and the number of display driver devices is consistent with the number of display components 21 on the circuit board 10. Each display driver device corresponds to a display component 21, thereby accurately controlling the brightness of the light emitted by each display component 21.

[0038] Example 2

[0039] 4 and 5 , the difference between this embodiment and embodiment 1 is that the number of display components 211 in some display assemblies 21 is preferably greater than the number of display components 211 in the remaining display assemblies 21 .

[0040] Specifically, the display assembly 21 includes a plurality of first display chips connected in series, each display component 211 corresponding to a first display chip. The display component 211 is provided on the first display chip, and the display pad is connected to the first display chip at the cathode end or the anode end. The display component 211 is a light-emitting element provided on the first display chip. The number of display components 21 is three, and they are respectively denoted as a red display assembly 21, a green display assembly 21, and a blue display assembly 21. The number of display components 211 of the green display assembly 21 is equal to the number of display components 211 of the blue display assembly 21, and the number of display components 211 of the red display assembly 21 is greater than the number of display components 211 of the green display assembly 21. Preferably, the number of display components 211 of the red display assembly 21 is three, and the number of display components 211 of the green display assembly 21 and the number of display components 211 of the blue display assembly 21 are both two. 4 , three display components 211 for displaying red light and connected in series are marked as D1 , two display components 211 for displaying green light and connected in series are marked as D2 , and two display components 211 for displaying blue light and connected in series are marked as D3 .

[0041] Example 3

[0042] The difference between this embodiment and embodiment 2 is that one of the display components 21 is recorded as a first display component 21, and the other two display components 21 are recorded as second display components 21. The first display component 21 includes multiple first display chips as in embodiment 2, the second display component 21 includes a second display chip, and multiple display components 211 are all located on the second display chip.

[0043] The display components 211 on the first display chip display blue or green light, while the display components 211 on the second display chip display red light. In this structure, multiple red display components 211 are integrated on a single high-voltage LED chip (i.e., the second display chip), achieving the same display effect as in Example 2 while also saving space and improving assembly efficiency.

[0044] Example 4

[0045] This embodiment differs from Embodiment 1 in that the number of display assemblies 21 is four, designated as a red display assembly 21, a green display assembly 21, a blue display assembly 21, and a white display assembly 21. The number of display components 211 in the green display assembly 21, the number of display components 211 in the blue display assembly 21, and the number of display components 211 in the white display assembly 21 are equal, while the number of display components 211 in the red display assembly 21 is greater than the number of display components 211 in the green display assembly 21. In this embodiment, the addition of the white display assembly 21 improves display brightness, making it suitable for outdoor use under strong sunlight.

[0046] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application.
