Description

Technical Field

[0001] The utility model relates to the technical field of digital display, in particular to an FPC digital display device. Background Art

[0002] In the digital display field, FPCs are used in a variety of display devices, such as smartphones, tablets, laptops, digital cameras, and medical devices. They are typically used to connect electronic components such as displays, touch screens, and cameras. Compared to traditional rigid circuit boards, FPCs offer higher reliability and interference immunity, while also reducing product size and weight, improving aesthetics, and enhancing flexibility. FPCs have diverse applications in the digital display field, not only providing design flexibility but also meeting the demands of modern electronic products for thinness, portability, and high performance. With continued technological advancement and market expansion, FPCs will play an even more important role in the digital display field in the future.

[0003] Currently, traditional digital display devices are all single-sided displays. Sometimes, in order to fully display the image, four display panels are added to form a four-sided square display screen for display. However, there are still blind spots in the display. Moreover, the heat dissipation of such traditional flat digital display devices mostly relies on aluminum heat sinks, which are not very efficient and shorten the service life of the components.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figures 1 to 4The utility model provides a technical solution: an FPC digital display device, comprising a base 1, the base 1 is also provided with an external wire for an external power supply, a cylindrical shell 2 is provided on the surface of the base 1, a card hole 14 is opened on the side of the cylindrical shell 2, and a snap fastener 15 is provided on the side of the base 1 corresponding to the card hole 14, so that the cylindrical shell 2 can be installed on the base by snapping, so as to facilitate assembly, a heat dissipation fan 3 is provided on the top of the base 1, which cooperates with the heat dissipation gap 13 between the battery block 10 and the protective back steel 8 and the air permeability gap 12 between the protective top cover 11 and the cylindrical shell 2 to blow air upward to take away the heat generated by the operation of the components for heat dissipation, and can perform air cooling on the battery block 10 and the flexible printed circuit board 4, thereby greatly reducing the operating temperature of its components and extending the service life of the device;

[0020] A flexible printed circuit board 4 is provided on the inner wall of the cylindrical shell 2. By coordinating the cylindrical shell 2 with the flexible printed circuit board 4, the device can achieve a three-dimensional 360-degree surround display, thereby expanding the display range of the device. A light-emitting chip 5 is provided on the surface of the flexible printed circuit board 4. A light-transmitting hole 6 is provided on the outer surface of the cylindrical shell 2 corresponding to the position of the light-emitting chip 5. The number of the light-emitting chips 5 matches the number of the light-transmitting holes 6. The light-transmitting holes 6 can not only allow the light of the light-emitting chip 5 to pass through the cylindrical shell 2, but also effectively prevent the adjacent light-emitting chips 5 from being too close and merging together, thereby affecting the display effect. A translucent protective film 7 is also provided on the surface of the cylindrical shell 2. The protective film 7 is provided to protect the cylindrical shell 2 and prevent splashes or dust from entering the light-transmitting holes 6, while ensuring aesthetics. A protective back steel 8 is provided on the back of the flexible printed circuit board 4. The protective back steel 8 is used to protect the back of the flexible printed circuit board 4.

[0021] A cross connecting plate 9 is provided inside the protective back steel 8. A connecting line connecting the battery block 10 and the flexible printed circuit board 4 is provided inside the cross connecting plate 9. Another connecting line is provided to connect the heat dissipation fan 3, so that the battery block 10, the flexible printed circuit board 4 and the heat dissipation fan 3 are electrically connected together (not shown). A display controller is provided at the bottom of the cross connecting plate 9, and a battery block 10 is provided on the top of the cross connecting plate 9. A protective top cover 11 for enhancing protection is provided on the top of the battery block 10. A ventilation gap 12 is provided between the protective top cover 11 and the cylindrical shell 2. The diameter of the battery block 10 is smaller than the inner diameter of the protective back steel 8, so that there is a heat dissipation gap 13 between the battery block 10 and the protective back steel 8, so as to facilitate the wind generated by the heat dissipation fan 3 to flow between the battery block 10 and the protective back steel 8, and be taken away to the outside air through the ventilation gap 12 for better heat dissipation.

[0022] In the present invention, the working steps of the device are as follows:

[0023] When in use, the display controller controls the light-emitting chip 5 on the flexible printed circuit board 4 to perform a 360-degree surround display, and the cooling fan 3 starts to run and blows air upward to take away the heat generated by the operation of the components and dissipate heat, thereby cooling the battery block 10 and the flexible printed circuit board 4 with air.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
