The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0027] like Figure 1 and Figure 2 As shown, this embodiment provides an OLED module, including a frame 7, the frame 7 is provided with a receiving groove, and a PCB circuit board 6, a fiber layer 5, a heat dissipation component 3, an OLED display screen 1 and a polarizer 201 are stacked in sequence along the direction from the bottom of the receiving groove to the top of the receiving groove, and the PCB circuit board 6 is electrically connected to the OLED display screen 1; the heat dissipation component 3 includes a mounting back plate 301 and a heat dissipation film 304 mounted on the upper surface of the mounting back plate 301, the lower surface of the mounting back plate 301 is bonded to the fiber layer 5, the heat dissipation film 304 is bonded to the lower surface of the OLED display screen 1, and the polarizer 201 is bonded to the upper surface of the OLED display screen 1 through the adhesive layer 203.
[0028] The OLED module uses the design of direct contact between the heat dissipation film 304 and the OLED display screen 1 to ensure smooth heat dissipation at the OLED display screen 1 and improve the heat dissipation effect of the OLED display screen 1; the fiber layer 5 is used to improve the overall bending resistance of the OLED module; and the polarizer 201 is used to eliminate dazzling reflected light and scattered light, turning messy light into parallel light, making the vision clearer and softer; the frame 7 is used to ensure the protection effect of other components on the OLED module; the PCB circuit board 6 is electrically connected to the OLED display screen 1 to ensure the stable operation of the OLED module. The above structural design is helpful to achieve the improvement of thinning and power consumption of the OLED module, and is convenient for improving the ultra-thin and low-power consumption design of the OLED module.
[0029] In this embodiment, the upper plate surface of the mounting back plate 301 is provided with a plurality of protrusions 302 spaced evenly along the first direction, and the protrusions 302 are provided with mounting grooves extending along the second direction, and a heat dissipation film 304 is installed in each mounting groove; wherein the first direction is perpendicular to the second direction. The above design limits the arrangement of the heat dissipation film 304 on the mounting back plate 301, optimizes the heat dissipation effect of the heat dissipation film 304, thereby reducing the layout area of the heat dissipation film 304, reducing the setting cost of the heat dissipation component 3, and also facilitating the gas flow between the mounting back plate 301 and the OLED display screen 1. The above improvement improves the heat dissipation of the heat dissipation component 3 to the OLED display screen 1, accelerates the cooling speed at the OLED display screen 1, and also reduces the manufacturing cost of the heat dissipation component 3.
[0030] Furthermore, the OLED module also includes an insulating sleeve 401, which is installed in the receiving groove, the outer ring of the insulating sleeve 401 matches and fits with the groove wall of the receiving groove, and the inner ring of the insulating sleeve 401 is simultaneously sleeved on the PCB circuit board 6, the fiber layer 5, the heat dissipation component 3, the OLED display screen 1 and the polarizer 201. The setting of the insulating sleeve 401 plays a role in reducing the impact on both sides of the insulating sleeve 401, and can protect the side of the OLED display screen 1 during assembly, preventing the frame 7 from causing wear on the side of the OLED display screen 1, thereby reducing the risk of damage to the components on the OLED module, reducing the probability of failure of the OLED module, and extending the service life.
[0031] Furthermore, the insulating sleeve 401 is penetrated by two mutually opposite elongated through holes 402, the length direction of the elongated through holes 402 extends along the second direction, and the heat dissipation films 304 located on both sides extend into the elongated through holes 402. The above design can expand the layout range of the heat dissipation films 304, not only allowing part of the heat to be discharged from the elongated through holes 402, but also allowing the heat dissipation films 304 to suppress the temperature rise of the insulating sleeve 401 near the elongated through holes 402, thereby improving the heat dissipation effect of the heat dissipation component 3 and enhancing the heat dissipation capacity of the heat dissipation component 3.
[0032] Exemplarily, the material of the insulating sleeve 401 is rubber. Rubber has the advantages of high structural stability, good insulation performance and good buffering effect, thereby reducing impact and avoiding leakage, which is conducive to the long-term stable operation of the OLED module. In other implementations of this embodiment, the insulating sleeve 401 adopts other elastic insulating materials. The selection of specific materials is determined by technicians in this field, and the specific determination method is a conventional technical means in this field, which will not be repeated here.
[0033] In this embodiment, a pressing protrusion is provided around the inner wall of the receiving groove, and the pressing protrusion presses against the upper plate surface of the polarizer 201. The setting of the pressing protrusion realizes the positioning design of the PCB circuit board 6, the fiber layer 5, the heat dissipation component 3, the OLED display screen 1 and the polarizer 201, reduces the risk of the above components detaching from the receiving groove due to accident, ensures the determination of the relative positions between the components on the OLED module, ensures the stable operation of the OLED module, and prolongs the service life of the OLED module.
[0034] Furthermore, the pressing protrusion is arranged at the top of the accommodating groove. The design of the pressing protrusion being arranged at the top of the accommodating groove realizes the structural optimization of the accommodating groove, reduces the space required for the accommodating groove, thereby reducing the volume of the frame 7. The above improvements are helpful to realize the ultra-thin design of the OLED module.
[0035] Specifically, the pressing protrusion is integrally formed on the frame 7. The design of integrally forming the pressing protrusion on the frame 7 reduces the processing cost of the pressing protrusion and reduces the manufacturing difficulty of the frame 7. The above improvements help to speed up the production speed of the frame 7 and improve the structural strength of the OLED module.
[0036] In this embodiment, a plurality of support columns 202 are further disposed in the receiving groove, and the plurality of support columns 202 are spaced around the OLED display screen 1 , one end of the support column 202 is fixedly connected to the polarizer 201 , and the other end is fixedly connected to the upper plate surface of the mounting back plate 301 .
[0037] By providing the support column 202, the polarizer 201 and the heat dissipation assembly 3 can be supported, providing a space for the OLED display screen 1, thereby avoiding direct contact between the polarizer 201 and the OLED display screen 1, thereby avoiding the risk of scratching the OLED display screen 1. The above improvements achieve the purpose of protecting the OLED display screen 1, reduce the risk of damage to the OLED display screen 1, and improve the user experience.
[0038] Exemplarily, the mounting back plate 301 has a plurality of through slots 303, and the plurality of through slots 303 are evenly spaced. The provision of the through slots 303 achieves a lightweight improvement of the mounting back plate 301, reduces the weight of the mounting back plate 301, improves the heat dissipation capacity of the mounting back plate 301, and improves the heat dissipation effect of the OLED module.
[0039] In this embodiment, the material of the frame 7 is metal. Specifically, the frame 7 is an iron frame. The metal frame 7 has the advantages of high structural stability and low production cost, and can smoothly achieve the purpose of protecting other components on the OLED module, which is conducive to the long-term stable operation of the OLED module. In other implementations of this embodiment, the frame 7 adopts other high-strength materials. The selection of specific materials is determined by technicians in this field, and the specific determination method is a conventional technical means in this field, which will not be repeated here.
[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention.
