Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic display, in particular to a display device with adjustable brightness. BACKGROUND

[0002] As the core interface of human-computer interaction, display plays a key role in outputting visual information in high-end fields such as industrial automation control, medical surgery navigation, aerospace monitoring, and in civilian scenarios such as education and gaming. With the widespread application of 8K ultra-high-definition display and high dynamic range technology, and the increasing demand for 24-hour continuous operation of equipment, the power density of the light-emitting elements inside the display continues to rise, leading to more prominent problems of local thermal stress concentration and insufficient mechanical stability. At the same time, the complexity of environmental light conditions puts forward higher requirements for the real-time and accuracy of screen brightness adjustment, and the traditional adjustment method is difficult to adapt to multiple scene requirements.

[0003] In the prior art, there are significant shortcomings in the thermal management and structural design of the display: conventional heat dissipation schemes mostly rely on single-layer heat conduction of aluminum substrates or graphite sheets, the heat conduction path is single and the interface contact thermal resistance is high, which leads to thermal expansion deformation in high heat flux density areas, accelerating the aging of the backlight module; and the support structure generally adopts a homogenized frame design, lacks directional reinforcing ribs and composite protective layers, and is prone to mechanical damage to the panel and the driving circuit board under vibration, drop and other working conditions. In addition, brightness adjustment mostly relies on software control or simple knobs, lacks precise mechanical transmission mechanisms and physical positioning feedback, and is difficult to achieve stepless and accurate adjustment, and is prone to brightness drift caused by gear wear in frequent operation. Therefore, there is an urgent need for an integrated display structure that combines efficient heat conduction, impact-resistant reinforcement and physical precise adjustment to meet the reliability challenges and user experience upgrade requirements in harsh working conditions. Practical new type content

[0004] In order to solve the problems mentioned in the background art, the present application provides a display device with adjustable brightness.

[0005] The display device with adjustable brightness provided by the present application adopts the following technical solution: a rotating structure for adjusting the brightness of the display, a stabilizing structure for improving the efficiency of the display, a connecting rod fixedly connected to the outer side of the stabilizing structure, the connecting rod fixedly connected to the frame on the outer side, and the rotating structure arranged on the other side of the stabilizing structure; the stabilizing structure comprises a stabilizing layer, a heat absorbing layer fixedly connected to the middle of the rear side of the stabilizing layer, a reinforcing rib arranged on one side of the heat absorbing layer, and a protective layer fixedly connected to one side of the reinforcing rib.

[0006] Optionally, the rotating structure includes a rotating shaft, a protective ring fixedly connected to one side of the rotating shaft, a rotating rod fixedly connected to one side of the protective ring, a gear fixedly connected to the outer side of the rotating rod, a transmission rod fixedly connected to one side of the gear, and a positioning seat provided at the bottom of the transmission rod.

[0007] With the above solution, the protective ring fixedly connected to one side of the rotating shaft in the rotating structure can protect the rotating shaft and reduce wear; the rotating rod connected to the other side of the protective ring is responsible for driving the operation; there is a gear on the outside of the rotating rod, and a transmission rod connected to one side of it further drives the positioning seat, which ensures the stability and accuracy of the entire rotating structure and allows for flexible adjustment of the display brightness.

[0008] Optionally, a display body is provided on one side of the connecting rod, a rotating shaft is provided on the outer side of the display body, and a heat-absorbing layer is provided on one side of the rotating shaft.

[0009] With the above solution, the monitor body is installed on one side of the connecting rod, and a pivot is configured on the outside of the monitor body, which allows the monitor to be rotated and adjusted to meet different viewing angle requirements; while a heat-absorbing layer is set on one side of the pivot, which can absorb and disperse the heat generated by the monitor during operation, ensuring that the monitor maintains stable performance during long-term use.

[0010] Optionally, the heat-absorbing layer is made of thermally conductive silicone grease, and the reinforcing ribs are made of polycarbonate.

[0011] The above solution uses thermally conductive silicone grease for the heat absorption layer, which can quickly dissipate the heat generated by the display. The reinforcing ribs are made of polycarbonate, which can enhance the overall strength of the stable structure and protect the internal components from external impacts.

[0012] Optionally, the protective layer is a fluorinated polymer material, and the stabilizing layer is a carbon fiber composite material.

[0013] The above solution uses fluoropolymer materials for the protective layer, which can effectively protect internal components from external environmental corrosion and reduce wear; the stabilizing layer uses carbon fiber composite materials, which provide support for the display and ensure the stability and reliability of the overall structure.

[0014] Optionally, the heat-absorbing layer has a thickness of 0.2mm-0.35mm, the reinforcing rib has a thickness of 0.3mm-0.35mm, and the stabilizing layer has a thickness of 0.2mm-0.15mm.

[0015] Through the above solution, the thickness of the heat-absorbing layer enables it to effectively absorb and disperse the heat generated by the display, the thickness of the reinforcing ribs can enhance the overall strength of the stable structure, and the thickness of the stabilizing layer provides sufficient support while ensuring the lightness and portability of the entire structure.

[0016] In summary, this application includes the following beneficial technical effects:

This utility model, by setting up a stable structure and its internal components such as a stable layer, a heat-absorbing layer, reinforcing ribs, and a protective layer, provides basic support through the stable layer, absorbs and disperses the heat generated during the operation of the display through the heat-absorbing layer, strengthens the structure by reinforcing ribs, and provides additional protection through the protective layer. This allows the stable structure to perform thermal management and structural reinforcement of the display. It can solve the problems of heat accumulation and insufficient structural strength during the operation of the display, thereby improving the working efficiency of the display and extending its service life.

[0018] 2. This utility model, by setting up a rotating structure and its internal components such as a rotating shaft, protective ring, rotating rod, transmission rod, and positioning seat, achieves the rotation function through the rotating shaft, the protective ring protects the rotating shaft from external damage, the rotating rod and transmission rod transmit rotational force, and the positioning seat ensures the stability of the rotating structure.

[0023] The following is in conjunction with the appendix Figs. 1-3 This application will be described in further detail.

[0026] It should be explained that the stabilizing structure 2 is firmly connected to the frame 1 by the outer connecting rod 4, providing support for the display. The stabilizing structure 2 has a stabilizing layer 21 inside, and a heat-absorbing layer 22 is tightly attached to the middle of its rear side, which effectively absorbs and disperses the heat generated when the display is working. The reinforcing ribs 23 on the side of the heat-absorbing layer 22 enhance the strength and stability of the overall structure. The other side of the reinforcing ribs 23 is covered with a protective layer 24, which protects the internal components and ensures that the display can maintain efficient operation and structural stability when adjusting the brightness, thus extending its service life.

[0027] Please see Figs. 1 to 3 The rotating structure 3 includes a rotating shaft 31, a protective ring 32 fixedly connected to one side of the rotating shaft 31, a rotating rod 34 fixedly connected to one side of the protective ring 32, a gear 33 fixedly connected to the outside of the rotating rod 34, a transmission rod 36 fixedly connected to one side of the gear 33, and a positioning seat 35 provided at the bottom of the transmission rod 36.

[0028] It should be explained that the rotating structure 3 has a rotating shaft 31, one side of which is tightly fixed with a protective ring 32 to protect the rotating shaft 31 from wear and external interference. The other side of the protective ring 32 is connected to a rotating rod 34, and a gear 33 is installed on the outside of the rotating rod 34. The working is driven by the gear 33. One side of the gear 33 is connected to a transmission rod 36, which drives the positioning seat 35 at the bottom. The positioning seat 35 makes the entire rotating structure 3 stable and accurate during rotation, and accurately adjusts the brightness of the display.

[0029] Please see Figs. 1 to 3 A display body 5 is provided on one side of the connecting rod 4, a rotating shaft 31 is provided on the outside of the display body 5, and a heat-absorbing layer 22 is provided on one side of the rotating shaft 31.

[0030] It should be explained that the monitor body 5 is securely mounted on one side of the connecting rod 4, which can display images and information. A pivot 31 is set on its outer side, which can support the rotation adjustment of the monitor body 5 and allow users to flexibly adjust the viewing angle as needed. A heat-absorbing layer 22 is located on one side of the pivot 31, which effectively absorbs the heat generated when the monitor is working, making the monitor more stable and reliable during long-term use.

[0031] Please seeFigs. 1 to 3 The heat-absorbing layer 22 is made of thermally conductive silicone grease, and the reinforcing rib 23 is made of polycarbonate.

[0032] It should be explained that the heat-absorbing layer 22 uses thermally conductive silicone grease, which can quickly transfer the heat generated inside the display to the outside, effectively preventing heat accumulation from affecting the display performance. The reinforcing rib 23 is made of polycarbonate, which can enhance the stability of the display structure and reduce the overall weight.

[0033] Please see Figs. 1 to 3 The protective layer 24 is made of fluorinated polymer material, and the stabilizing layer 21 is made of carbon fiber composite material.

[0034] It should be explained that the protective layer 24 is made of fluorinated polymer material, which can effectively resist the corrosion of the external environment and reduce wear, while the stabilizing layer 21 uses carbon fiber composite material, which makes the overall structure stable and reliable in complex environments, making the display more durable and stable.

[0035] Please see ​ The heat-absorbing layer 22 has a thickness of 0.2mm-0.35mm, the reinforcing rib 23 has a thickness of 0.3mm-0.35mm, and the stabilizing layer 21 has a thickness of 0.2mm-0.15mm.

[0036] It should be explained that the thickness of the heat-absorbing layer 22 can efficiently dissipate heat and effectively control weight and volume, the thickness of the reinforcing rib 23 enhances the stability of the structure, and the thickness of the stabilizing layer 21 provides support while maintaining the overall lightness and portability.

[0037] The implementation principle of an adjustable brightness display device according to an embodiment of this application is as follows:

[0038] First, in the stabilizing structure 2, the carbon fiber composite stabilizing layer 21 provides support, while the thermally conductive silicone grease heat-absorbing layer 22 in the middle of its rear side quickly absorbs the heat generated during the operation of the display and transfers the heat to the outside through the material properties, effectively preventing heat accumulation from affecting performance. At the same time, the polycarbonate material reinforcing ribs 23, with a thickness of 0.3mm-0.35mm, enhance the structural strength, while the fluorinated polymer protective layer 24 resists external corrosion and protects the internal components from wear.

[0039] Secondly, the rotating structure 3 achieves precise adjustment of the display brightness through the rotating shaft 31 and its associated components. A protective ring 32 on one side of the rotating shaft 31 reduces wear and interference. The meshing transmission between the rotating rod 34 and the gear 33 transmits rotational power to the transmission rod 36, and finally, the positioning seat 35 ensures the stability and accuracy of the rotation process. Users can flexibly adjust the display viewing angle by operating the rotating structure 3, while the heat-absorbing layer 22 beside the rotating shaft 31 continuously operates to maintain the display's temperature stability during prolonged use.

[0040] Finally, the connecting rod 4 securely connects the stabilizing structure 2 to the frame 1, providing support for the entire device. The display body 5 is mounted on one side of the connecting rod 4, and its outer hinge 31 not only supports the rotation adjustment function, but also further optimizes the heat dissipation effect through the heat absorption layer 22 on the side, making the display more efficient, stable and durable when adjusting brightness.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
