Description

Technical Field

[0001] This utility model relates to the field of display modules, and in particular to an LED lamp-type display module. Background Technology

[0002] Display modules are an indispensable part of modern electronic devices, widely used in various instruments, meters, indicators, and displays. Traditional display modules often employ LCD (Liquid Crystal Display) or digital tube display technologies in their design and application. Specifically, traditional digital tube displays are relatively less flexible, struggling to meet diverse display needs and lacking performance in complex display scenarios. On the other hand, while traditional LCD technology improves display quality to some extent, it still has significant limitations, particularly in temperature resistance, failing to operate stably in extreme temperature environments. Furthermore, its brightness often falls short of the requirements for high-brightness environments, resulting in unsatisfactory display effects. While OLED screen technology, currently popular in the market, is less bright than LCD, its high cost is a major factor limiting its widespread adoption. This forces many manufacturers to weigh the pros and cons when selecting display technologies, comprehensively considering the balance between performance and cost. Utility Model Content

[0003] The technical problem solved by this utility model is to provide an LED lamp-type display module that is more flexible and lower in cost.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an LED lamp display module, including a PCB board, on which multiple LED lamps are arranged, a light-blocking shield is arranged on one side of the PCB board, the light-blocking shield is arranged on the side of the PCB board where the LED lamps are arranged, the light-blocking shield is used to isolate the multiple LED lamps from each other, a light-transmitting PC cover is arranged on the side of the light-blocking shield away from the PCB board, and an opaque soft PC film is arranged on the side of the light-transmitting PC cover away from the light-blocking shield, the opaque soft PC film is provided with a light-transmitting pattern, and a front cover for fixing the PCB board, the light-blocking shield, the PC cover and the opaque soft PC film.

[0005] Furthermore, the light-blocking shield has multiple first hollow units corresponding to the LED lights, and the light-blocking shield has multiple sets of isolation plates on the side facing the PCB board. Each set of isolation plates corresponds to a first hollow unit, and each LED is located in a different set of isolation plates.

[0006] Furthermore, the first hollow unit is circular, square, or irregular in shape.

[0007] Furthermore, the light-transmitting PC cover and the opaque soft PC film are bonded together.

[0008] Furthermore, the side of the light-transmitting PC cover is provided with a positioning protrusion, and the inner side of the front cover is provided with a positioning groove that cooperates with the positioning protrusion.

[0009] Furthermore, the light-blocking shield is provided with snap-fit ​​posts, and the PCB board is provided with snap-fit ​​holes that cooperate with the snap-fit ​​posts. The light-blocking shield and the PCB board are snapped together by the snap-fit ​​posts and snap-fit ​​holes.

[0010] Furthermore, the light-blocking shield has a slot on its side, and the front cover has a snap-fit ​​protrusion on its inner side that mates with the slot. The light-blocking shield and the front cover are connected by the slot and the snap-fit ​​protrusion.

[0011] The beneficial effects of this invention are as follows: Compared with traditional display modules, the LED lamp-type display module of this invention has higher flexibility and lower cost.

Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 6 As shown, an embodiment of this application discloses an LED lamp 2 type display module, including a PCB board 1, on which a plurality of LED lamps 2 are disposed. A light-blocking shield 3 is disposed on one side of the PCB board 1, on the side of the PCB board 1 where the LED lamps 2 are disposed. The light-blocking shield 3 is used to isolate the plurality of LED lamps 2 from each other. A light-transmitting PC cover plate 4 is disposed on the side of the light-blocking shield 3 away from the PCB board 1. An opaque soft PC film 5 is disposed on the side of the light-transmitting PC cover plate 4 away from the light-blocking shield 3. A light-transmitting pattern 51 is disposed on the opaque soft PC film 5. The module also includes a front cover 6 for fixing the PCB board 1, the light-blocking shield 3, the PC cover plate, and the opaque soft PC film 5.

[0021] It should be explained that a coating process is used on an opaque flexible PC film to make the light-transmitting pattern appear as if it is leaking light.

[0022] Specifically, in the above structure, the light-blocking shield 3 effectively isolates the light between each LED 2, allowing each LED 2 to independently pass through the light-transmitting PC cover 4 and emerge from the light-transmitting pattern 51 set on the opaque soft PC film 5. This ensures that the surface of the display module only displays the appearance of the light-transmitting pattern 51, and the style of the light-transmitting pattern 51 can be designed according to actual needs, greatly improving the flexibility of the display module. Furthermore, since LEDs 2 are used as display units, compared to traditional LCD liquid crystal display technology and digital tube display technology, the display module of this invention has a cost advantage. At the same time, the high brightness and good temperature resistance of LEDs 2 enable the display module to work stably in various environments and maintain good display effects.

[0023] In this embodiment, as Figure 2 and Figure 3As shown, the light-blocking shield 3 has multiple first hollow units 31 that correspond one-to-one with the LED lights 2. The light-blocking shield 3 has multiple sets of isolation plates 32 on the side facing the PCB board 1. Each set of isolation plates 32 corresponds one-to-one with the first hollow unit 31. Each LED is located in a different set of isolation plates 32. The first hollow unit 31 is circular, square or irregular in shape.

[0024] Specifically, the design of the first hollow unit 31 allows the light from the LED lamp 2 to pass directly through the light-blocking shield 3, while the presence of the isolation plate 32 effectively avoids light interference between adjacent LED lamps 2, ensuring the clarity and accuracy of the display effect. In addition, the shape of the first hollow unit 31 can be designed according to actual needs, such as circular, square, or irregular shapes, to adapt to different display requirements and application scenarios.

[0025] In this embodiment, the light-transmitting PC cover plate 4 and the opaque soft PC film 5 are bonded together.

[0026] Specifically, the adhesive connection between the translucent PC cover plate 4 and the opaque flexible PC film 5 not only ensures the structural stability of the display module but also effectively prevents external light from interfering with the display effect. The translucent PC cover plate 4 has good light transmittance and impact resistance, protecting the internal LED lamps 2 and light-blocking shield 3 from external damage, while ensuring that the light from the LED lamps 2 can pass through uniformly and clearly. The opaque flexible PC film 5 plays a further role in light control. Through the light-transmitting pattern 51 set on it, the position and shape of the light transmission can be precisely controlled, thereby achieving diverse display effects.

[0027] In this embodiment, as Figure 4 As shown, the light-transmitting PC cover plate 4 has a positioning protrusion 41 on its side, and the front cover 6 has a positioning groove 61 that cooperates with the positioning protrusion 41 on its inner side.

[0028] Specifically, the design of the positioning protrusion 41 and the positioning groove 61 allows the light-transmitting PC cover 4 to be accurately and securely installed inside the front cover 6, preventing positional shifts or shaking during installation and use. This precise positioning method not only improves the overall structural stability of the display module but also ensures the accuracy and consistency of the display effect. At the same time, the cooperation between the positioning protrusion 41 and the positioning groove 61 makes the assembly process simpler and faster, improving installation efficiency.

[0029] In this embodiment, the light-blocking shield 3 is provided with a snap-fit ​​post 33, and the PCB board 1 is provided with a snap-fit ​​hole that cooperates with the snap-fit ​​post 33. The light-blocking shield 3 and the PCB board 1 are snapped together by the snap-fit ​​post 33 and the snap-fit ​​hole.

[0030] Specifically, the design of the snap-fit ​​post 33 and the snap-fit ​​hole enables a quick and stable connection between the light-blocking shield 3 and the PCB board 1. This snap-fit ​​method not only simplifies the assembly process but also improves the overall structural strength of the display module. During assembly, simply align the snap-fit ​​post 33 with the snap-fit ​​hole and press gently to achieve a tight connection between the light-blocking shield 3 and the PCB board 1, without the need for additional fasteners or tools, greatly reducing assembly costs and time. At the same time, the tight fit between the snap-fit ​​post 33 and the snap-fit ​​hole effectively prevents loosening or detachment during use, ensuring the stability and reliability of the display module.

[0031] In this embodiment, the light-blocking shield 3 is provided with a slot 34 on its side, and the front cover 6 is provided with a snap-fit ​​protrusion 62 that cooperates with the slot 34 on its inner side. The light-blocking shield 3 and the front cover 6 are connected through the slot 34 and the snap-fit ​​protrusion 62.

[0032] Specifically, the design of the slot 34 and the snap-fit ​​protrusion 62 further enhances the stability of the connection between the light-blocking baffle 3 and the front cover 6. During assembly, the cooperation between the slot 34 and the snap-fit ​​protrusion 62 ensures that the light-blocking baffle 3 is accurately and firmly fixed to the front cover 6, effectively avoiding loosening or displacement problems that may occur during use. This design not only improves the overall structural strength of the display module but also ensures a tight fit between the various components, thereby guaranteeing the stability and consistency of the display effect. At the same time, the connection method of the slot 34 and the snap-fit ​​protrusion 62 simplifies the assembly process, improves assembly efficiency, and makes the manufacturing of the display module more convenient and economical.

[0033] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
