[0029] Example 1

[0030] Combination Figures 1 to 5 As shown, the display module of this utility model is schematically illustrated, including a substrate 10 and a plurality of light strips 20.

[0031] like Figure 3 The substrate 10 has a long strip structure and serves as a circuit board. Multiple light strips 20 are arranged parallel to each other and perpendicular to the substrate 10. Specifically, each light strip 20 is a long strip-shaped structure, perpendicular to the substrate 10, and its length direction is perpendicular to the length direction of the substrate 10. One side of the light strip 20 in the width direction is detachably electrically connected to the substrate 10, and the other side in the width direction is provided with a light-emitting element 30. The light-emitting element 30 can be an LED light-emitting bead or an LED light-emitting chip. The light-emitting elements 30 on multiple light strips 20 are combined to form an image. The space between two adjacent light strips 20 not only allows light to pass through to achieve the light transmission function of the display module but also allows airflow to pass through and dissipate heat from the light-emitting elements 30 on the light strip 20. The light-emitting elements 30 positioned on the sides of the light strip 20 improve the color rendering accuracy of the display module. In contrast, in traditional display modules, the light-emitting elements 30 are positioned on the front of the light strip 20. When multiple light strips 20 are parallel to each other, the light-emitting element 30 on the middle light strip 20 faces the back of another light strip 20, while the user is positioned to the side of the light strip 20. This means the light-emitting elements 30 on the light strip 20 are not directly facing the user, resulting in a color cast when observed by the user. Specifically, each light strip 20 has multiple light-emitting elements 30. The light-emitting elements 30 on adjacent light strips 20 are aligned along the normal direction of the light strip 20. The number of light-emitting elements 30 on adjacent light strips 20 satisfies the condition that the longer light strip 20 has more light-emitting elements 30 than the shorter light strip 20. This results in a matrix arrangement of the light-emitting elements 30 on the display module, and the edge shape of the displayed image matches the edge shape (triangle) of the structure formed by the multiple light strips 20.

[0032] To allow for flexible adjustment of the length of the light strip 20, at least one light strip 20 in the display module has multiple light-emitting segments 22. These segments are connected end-to-end, with adjacent segments electrically connected. Each segment 22 is equipped with a light-emitting element 30. The light-emitting segment 22 at one end of the light strip 20 is detachably connected to the substrate 10. Multiple light-emitting segments 22 can form a longer light strip 20. For example, in the display module, one light strip 20 may have three light-emitting segments 22, and another may have one. The light-emitting segment 22 at one end of the light strip 20 is provided with a first terminal 21 and connected to a second terminal 11 of the substrate 10. The other light-emitting segments 22 on the light strip 20 are powered through the light-emitting segment 22 with the first terminal 21. Further, as... Figure 5With the extension direction of the light strip 20 away from the substrate 10 as the first direction X, the connection between the light strip 20 and the substrate 10 is located at the end of the light strip 20 away from the first direction X, that is, the first terminal 21 is located at the end of the light strip 20 away from the first direction X. The light strip 20 is provided with a control chip 23, which is electrically connected to the light-emitting element 30 and controls the light-emitting element 30 to emit light. The control chip 23 and the light-emitting element 30 controlled by the control chip 23 are arranged sequentially along the first direction X. The two ends of the control chip 23 are respectively connected to the first terminal 21 and the light-emitting element 30. The light strip 20 can be cut with a tool (such as scissors). Multiple control chips 23 are provided on the light strip 20, each controlling multiple light-emitting elements 30. For example, a light strip 20 may have nine light-emitting elements 30, named as first light-emitting element 30a, second light-emitting element 30b, third light-emitting element 30c, ..., eighth light-emitting element 30h, ninth light-emitting element 30i. The light strip 20 has three control chips 23, named first control chip 23a, second control chip 23b, and third control chip 23c. The first control chip 23a is used to electrically connect to and control the first light-emitting elements 30a to the third light-emitting elements 30c; the second control chip 23b is used to electrically connect to and control the fourth light-emitting elements 30d to the sixth light-emitting elements 30f; and the third control chip 23c... 3c is used to electrically connect and control the seventh light-emitting element 30g to the ninth light-emitting element 30i. The first control chip 23a, the first light-emitting element 30a, the second light-emitting element 30b, and the third light-emitting element 30c are arranged sequentially along the first direction X. The second control chip 23b, the fourth light-emitting element 30d, the fifth light-emitting element 30e, and the sixth light-emitting element 30f are arranged sequentially along the first direction X. The third control chip 23c, the seventh light-emitting element 30g, the eighth light-emitting element 30h, and the ninth light-emitting element 30i are arranged sequentially along the first direction X. During the trimming of the light strip 20, even when trimming the area between the fourth light-emitting element 30d and the fifth light-emitting element 30e, the first control chip 23a and the second control chip 23b can still be electrically connected to the first terminal 21, preventing the circuit from the first light-emitting element 30a to the fourth light-emitting element 30d from being cut. This structure allows for mass production of the light strip 20. When customizing specific irregularly shaped displays, only the light strip 20 needs to be trimmed according to the actual design. This structure greatly reduces the production cost of irregularly shaped displays, significantly lowering their selling price.

[0033] The length of one of two adjacent light strips 20 is greater than the length of the other, so that the outer contour of the structure formed by multiple light strips 20 on the plane of the substrate 10 is triangular. The structure formed by multiple light strips 20 itself meets the requirements of irregular-shaped display screens, does not occupy additional space, and realizes the miniaturization of irregular-shaped screens.

[0034] The light strip 20 has a light-emitting side and a connecting side arranged opposite to each other. The light-emitting element 30 is located on the light-emitting side, and the light-emitting direction of the light-emitting element 30 is the same as that of the light-emitting side. This allows the light-emitting element 30 to face the user directly, ensuring accurate color rendering and consistent perceived brightness across all light-emitting elements 30. The connecting side has a first terminal 21, and the substrate 10 has a second terminal 11. The first terminal 21 and the second terminal 11 are interlocked, with the first terminal 21 located at one end of the connecting side. This structure allows the light strip 20 to be perpendicular to the substrate 10, ensuring electrical connection between the light strip 20 and the substrate 10 via the first terminal 21 and the second terminal 11, and allowing the light-emitting element 30 to face the user directly. In this embodiment, each light strip 20 has the aforementioned first terminal 21 at one end, and the substrate 10 has multiple second terminals 11 arranged in a straight line. Each first terminal 21 corresponds to one second terminal 11, aligning the ends of the multiple light strips 20 with the first terminal 21 to form one side of a triangle.

[0035] Combination Figure 2 and Figure 4 The display module also includes a frame 40, which is triangular in shape. A substrate 10 is located on one side of the frame 40. One end of a light strip 20 is detachably connected to the substrate 10, and the middle and / or the other end of the light strip 20 are detachably connected to the frame 40. The frame 40 supports the substrate 10 and multiple light strips 20, and improves the impact resistance of the display module. A connecting component 41 is provided on the frame 40. The connecting component 41 includes two locking blocks 411 disposed on the frame 40 and arranged opposite to each other. The light strip 20 is embedded between the two locking blocks 411. The two locking blocks 411 clamp the light strip 20 to prevent abnormal shaking of the light strip 20 on the frame 40, which would affect the display effect. Furthermore, the frame 40 is provided with multiple connecting beams 42, which are arranged parallel to the base plate 10. Several connecting components 41 are provided on the connecting beams 42. Each light strip 20 can be detachably connected to the connecting beam 42 through the connecting components 41. The setting of the connecting beams 42 can limit the position of the light strip 20 to ensure that the spacing of two adjacent light strips 20 is consistent.

[0036] Example 2

[0037] The difference between this embodiment and Embodiment 1 is that the light-emitting element 30 has at least two LED beads 31 arranged side by side. Each LED bead 31 includes at least a red LED light-emitting chip, a green LED light-emitting chip, and a blue LED light-emitting chip. The light emitted by the three types of LED light-emitting chips can be combined to form any desired color. The light emission colors of the two LED beads 31 of the light-emitting element 30 can be the same or different. When the light emission colors of the two LED beads 31 are the same, the two LED beads 31 arranged side by side can significantly improve the light emission brightness of each light-emitting element 30. When the light emission colors of the two LED beads 31 are different, the light-emitting element 30 can display more colors.

[0038] Example 3

[0039] like Figure 6 This embodiment discloses a display device 1, including a housing 50 and a display module as described above. The outer contour of the housing 50 projected onto the plane of the substrate 10 is triangular. The housing 50 has a triangular through hole 51, and the display module is disposed in the through hole 51. The outer side of the frame 40 of the display module is detachably connected to the inner wall of the through hole 51 via existing connectors. This display device 1 has a light-transmitting display function, and the air flowing between adjacent lamp strips 20 can also dissipate heat for the light-emitting elements 30 and the light-emitting control chip 23 on the lamp strips 20.

[0040] In summary, the light strip 20 and the substrate 10 are arranged perpendicularly. One side of the light strip 20 is connected to the substrate 10, and the other side is provided with a light-emitting element 30. The gap between two adjacent light strips 20 can transmit light, realizing the light transmission effect of the display module. Taking the extension direction of the light strip 20 away from the substrate 10 as the first direction X, the connection between the light strip 20 and the substrate 10 is located at the end of the light strip 20 away from the first direction X. The light strip 20 is provided with a control chip 23. The control chip 23 and the light-emitting element 30 controlled by the control chip 23 are arranged sequentially along the first direction X. The substrate 10 can supply power to the light strip 20 and output control signals. The arrangement of the control chip 23 and the light-emitting element 30 on the light strip 20 can avoid the situation where the circuit of the light-emitting element 30 is accidentally cut when the light strip 20 is cut during the production process.
