Abstract
Description
Technical Field
[0001] This utility model relates to the field of display screen technology, and in particular to a circuit board display screen device with a stacked structure. Background Technology
[0002] As display technology continues to evolve, ultra-thin digital tube displays, as a core component of modern electronic devices, face increasingly stringent challenges in both performance and cost in their structural design. Although existing technologies have made certain achievements in this field, several key issues remain to be addressed, which significantly restrict the further development and widespread application of ultra-thin digital tube displays.
[0003] First, from the perspective of structural stability, some ultra-thin digital tube displays have to compromise on their structure in pursuit of extreme thinness, resulting in insufficient overall structural strength and susceptibility to damage. This structural fragility not only affects the durability of the display but also limits its applicability in complex and ever-changing application environments.
[0004] Secondly, brightness uniformity is one of the important indicators for evaluating display performance. However, some ultra-thin digital tube displays in the current technology suffer from unreasonable structural design, leading to scattering and uneven distribution of light as it propagates within the display, resulting in uneven brightness and severely affecting image clarity and visual comfort. This problem is particularly prominent in high-end display devices, becoming a key factor restricting their market acceptance.
[0005] Furthermore, energy efficiency is an issue that cannot be ignored in existing technologies. With increasing environmental awareness, low-power, high-efficiency display products are gaining popularity in the market. However, some ultra-thin digital tube displays, while pursuing high brightness, have high energy consumption, which not only increases the operating costs of the equipment but also runs counter to the current green and energy-saving concept.
[0006] Finally, from a manufacturing cost perspective, complex and sophisticated structural designs often translate to high production costs. While some existing ultra-thin digital tube displays offer superior performance, their high manufacturing costs limit their mass production and widespread application. How to reduce costs while maintaining performance has become a major challenge that the industry urgently needs to address. Utility Model Content

[0030] Please see Figures 1 to 3 This utility model provides a circuit board display device with a stacked structure, including a display housing 10 and a display integration module 20. The display integration module 20 is detachably mounted on the display housing 10. This detachable design makes the assembly and maintenance of the display device more convenient, improves the product's maintainability, and facilitates product upgrades and expansions. The display integration module 20 includes an integrated board 21, a display module circuit board 22, a light guide bracket 23, a patterned film layer 24, and a display protective layer 25, which are stacked sequentially. This stacked structure design not only achieves a thinner and lighter display but also significantly improves the stability and durability of the structure. The integrated board 21 is located between the display housing 10 and the display module circuit board 22, serving as a support and connection to ensure the stability of signal transmission. The integrated board 21 is electrically connected to the display module circuit board 22, achieving efficient and reliable circuit transmission. The display module circuit board 22 has LED beads 30 on the side near the light guide bracket 23, which are adapted to the pattern film layer 24. The precise layout of these LED beads 30 ensures that the angle of light emission is precisely matched with the light transmission design of the pattern film layer 24, thereby improving the display effect. The LED beads 30 are electrically connected to the display module circuit board 22, realizing a stable current supply and control, ensuring stable light emission and brightness adjustment of the LED beads 30. The light guide bracket 23 has clearance slots 231 corresponding to the LED beads 30, which not only provides sufficient light emission space for the LED beads 30, but also optimizes the light propagation path within the light guide bracket 23, reduces light loss, and further improves the brightness and uniformity of the display screen.
[0031] It should also be noted that the display casing 10 is for different product terminals. Specifically, it includes, but is not limited to, mobile phone cases, electric toothbrushes, earphone cases, and speakers.
[0032] In this embodiment, the pattern film layer 24 is used to display numbers, light effects, and patterns, enabling a rich variety of visual effects. The pattern film layer 24 includes a phosphor layer 241, a substrate layer 242, and a pattern layer 243 that are sequentially stacked and connected. The phosphor layer 241 is located between the light guide bracket 23 and the substrate layer 242, and the pattern layer 243 is located between the substrate layer 242 and the display screen protective layer 25, accurately displaying preset numbers, light effects, and patterns, ensuring the clarity and aesthetics of the display. The phosphor layer 241 is used to effectively absorb and efficiently convert the light emitted by the LED beads 30, that is, to convert the light emitted by the LED beads 30 into corresponding high-brightness fluorescence through the fluorescence effect, thereby improving the visual effect and color saturation of the display screen.
[0033] LED beads 30 are used to emit blue light. Blue light is a highly efficient and energy-saving light source. At the same time, through the conversion of phosphors, different colors of fluorescence can be emitted to achieve multi-color display.
[0034] The light guide bracket 23 can be either a flexible light guide bracket or a rigid light guide bracket. This design allows the light guide bracket 23 to be selected according to different application scenarios and needs, improving the adaptability and flexibility of the product.
[0035] Furthermore, the light guide bracket 23 can be any one of a polyethylene bracket, a thermosetting polyurethane bracket, and a thermoplastic polyurethane bracket. These materials all have good light guiding and mechanical properties, and can meet the needs of different application scenarios.
[0036] The integrated board 21 includes a circuit board body 211, a power-harvesting antenna 212, and a power supply component 213. The circuit board body 211, as the base material of the circuit board, possesses good insulation and mechanical strength. The power-harvesting antenna 212 receives external power signals, enabling wireless power supply. Both the power-harvesting antenna 212 and the power supply component 213 are mounted on the circuit board body 211. The power-harvesting antenna 212 and the display module circuit board 22 are electrically connected to the power supply component 213, ensuring a stable power supply for the display device.
[0037] Furthermore, the display protective layer 25 is a transparent layer that can protect the pattern film layer 24 from damage by the external environment, while maintaining the clarity and transparency of the display screen to ensure that users get the best visual experience.
[0038] In a preferred embodiment, the LED beads 30 include an LED light source matrix 31 and LED dot strips 32. This combination design greatly enriches the luminous effect and brightness distribution of the display screen. For example, the LED light source matrix 31 is located on the center of one side of the display module circuit board 22 near the light guide bracket 23, serving as the main light source and providing stable and uniform basic illumination. The LED dot strips 32 are arranged in a radiating pattern on the outer periphery of the LED light source matrix 31, which not only enhances the brightness of the edge area but also creates a dynamic and three-dimensional visual effect through its flexible light effect design. The clearance slot 231 includes a first clearance slot 2311 corresponding to the LED light source matrix 31 and a second clearance slot 2312 corresponding to the LED dot strips 32, ensuring sufficient light-emitting space for the LED beads 30, effectively avoiding light obstruction and scattering, further improving the brightness uniformity and light effect performance of the display screen, making the entire display screen more visually appealing.
[0039] Among them, the LED light source matrix 31 includes, but is not limited to, a 6×6 light source array to meet the needs of various application scenarios.
