Description

Technical Field

[0001] This utility model belongs to the field of LED display panel technology, and relates to a dual-color LED display panel. Background Technology

[0002] Existing LED dual-color display panels have significant drawbacks in terms of damage caused by high temperatures, mainly manifested in accelerated hardware failure, degraded display performance, and increased safety risks. On the hardware side, increased junction temperature of LED chips accelerates the aging of semiconductors and packaging materials. When the junction temperature exceeds 85℃, ordinary LED chips experience a 5% monthly light decay, drastically reducing their lifespan from the nominal 50,000-100,000 hours to below 30,000 hours, and also causing black spots and dark patches. High temperatures affect components such as driver chips and capacitors, causing parameter drift, leading to unstable current, uneven brightness, and even capacitor electrolyte drying and short circuits. In terms of performance, high temperatures reduce luminous efficiency and cause color drift. The encapsulating resin undergoes a phase change above 125℃, becoming rubbery, reducing light transmittance and exacerbating display distortion. From a safety perspective, localized overheating damages the insulation layer of electrical wires, easily causing short circuits and fires. The risks are more pronounced in large screens in densely populated areas. These drawbacks stem from the fact that dual-color displays require dual-path drivers, increasing power density. The efficiency of converting electrical energy into light energy is only 20%-30%, with the remaining energy converted into heat. Furthermore, the dense pixel density limits heat dissipation area, and the thermal conductivity bottleneck of the traditional substrate insulation layer exacerbates heat accumulation. Conventional solutions include natural heat dissipation (metal heat sinks), forced air cooling (fans), and liquid cooling. Natural heat dissipation is low-cost but inefficient and cannot meet the needs of high-power or high-temperature environments; air cooling is fast but fans generate noise and are easily damaged components requiring frequent maintenance, increasing costs. Therefore, there is an urgent need for a dual-color LED display panel to solve these problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dual-color LED display panel to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a dual-color LED display panel, comprising: a mounting plate, an inner mounting frame and a rear heat conduction port, wherein the front cross-section of the mounting plate is a rectangular structure, and the mounting plate is provided with a set of inner mounting frames for fitting and mounting with the display screen. The inner mounting frame includes an inner frame body and a color control cable. The front cross-section of the inner frame body is a rectangular structure. The inner side of the inner frame body is provided with a set of inner sealing rings for maintaining the seal of its internal mounting position. The top cross-section of the inner sealing rings is an elliptical ring structure. The outer side of the inner sealing rings is sealed and attached to the inner side of the inner frame body with sealant.

[0005] In a preferred embodiment, the inner sealing ring is provided in several groups, and each pair of inner sealing rings is sealed and bonded together by a set of sealant, and the several groups of inner sealing rings are connected and fixed by several sets of bolts.

[0006] In a preferred embodiment, the inner sealing ring is provided with several sets of inner temperature-conducting seats for mounting the heat dissipation crossbars. The inner temperature-conducting seats are hollow concave structures made of aluminum alloy. In actual use, the inner mounting frame, due to its elliptical ring structure and the sealing design with sealant, can effectively prevent external dust, moisture, and other impurities from entering the equipment. Multiple sets of inner sealing rings are fixed by bolts to form a multi-layered sealing protection, continuously maintaining a clean and dry environment inside the equipment and preventing impurities from affecting the performance of internal components. The hollow concave structure of the inner temperature-conducting seats, made of aluminum alloy, allows them to efficiently conduct the heat generated when the display screen is working and quickly transfer the heat to the heat dissipation crossbars. The heat dissipation crossbars, by increasing the heat dissipation area, further diffuse the heat into the air. The two work together to achieve efficient heat conduction and dissipation, preventing the display screen from experiencing performance degradation or damage due to excessive temperature and ensuring long-term stable operation of the equipment.

[0007] As a preferred embodiment, several sets of the inner temperature-conducting seats are spliced ​​together, and a set of temperature-conducting aluminum alloy plates is provided between every two sets of the inner temperature-conducting seats. Each set of the inner temperature-conducting seats has several sets of horizontal heat dissipation strips inside.

[0008] In a preferred embodiment, several sets of heat dissipation strips have the same structure and are fixedly connected to the interior of the inner temperature-conducting seat. The heat dissipation strips are arranged with an inclined structure, and several sets of heat dissipation strips inside each set of the inner temperature-conducting seat have a louvered structure.

[0009] As a preferred embodiment, a set of color control lines for adjusting a single hue is provided on the left side of the middle position of several sets of internal temperature-conducting seats, and a set of color control lines for adjusting a single hue is provided on the right side of the middle position of several sets of internal temperature-conducting seats.

[0010] In a preferred embodiment, a set of controllers for regulating the dual-color display of the display screen and an LED color control driver are provided inside the color control cable one and color control cable two, and the front sides of the color control cable one and color control cable two are connected to the display screen wires.

[0011] In a preferred embodiment, the mounting plate has a set of side positioning holes inside each of the four sets of external corners for positioning and installation. There are four sets of side positioning holes, and each set of side positioning holes has an internal thread groove for threaded connection with bolts. In actual use, since a controller and an LED color control driver are installed inside the color control cable one and color control cable two to control the dual-color display of the display screen, and the front of both are connected to the display screen wires, the color control cable one and color control cable two serve as signal transmission channels. Under the synergistic effect of the controller and the LED color control driver, the dual-color display control signal is accurately transmitted, so that the color adjustment command issued by the control device is accurately transmitted to the display screen, realizing accurate switching of dual-color display and uniform color presentation, and ensuring that the display effect meets the usage requirements.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: In actual use, the inner mounting frame, due to its elliptical ring structure and the sealing and bonding design with sealant, can effectively prevent external dust, moisture and other impurities from entering the equipment. Multiple sets of inner sealing rings are fixed by bolts to form a multi-layer sealing protection, continuously maintaining a clean and dry environment inside the equipment, and avoiding the impact of impurities on the performance of internal components. The inner temperature conducting seat adopts a hollow concave structure and is made of aluminum alloy. This design and material characteristics enable it to efficiently conduct the heat generated when the display screen is working and quickly transfer the heat to the heat dissipation strip. The heat dissipation strip further diffuses the heat into the air by increasing the heat dissipation area. The two work together to achieve efficient heat conduction and heat dissipation, preventing the display screen from experiencing performance degradation or damage due to excessive temperature, and ensuring long-term stable operation of the equipment. In practical use, a controller and an LED color control driver are internally installed between color control cable one and color control cable two to regulate the dual-color display of the screen. Both are connected to the screen's power cord at the front. As signal transmission channels, color control cable one and color control cable two accurately transmit dual-color display control signals under the coordinated action of the controller and LED color control driver. This ensures that the color adjustment instructions issued by the control device are accurately transmitted to the screen, achieving precise switching of dual-color display and uniform color presentation, and ensuring that the display effect meets the usage requirements.
