[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0023] The present application proposes a display module for reducing FPC stress, including: a display screen 10 and an FPC board 20, wherein the display screen 10 is provided with a display area and a non-display area, and the display area is used to display images. A circuit is provided on the FPC board 20, and the circuit can realize the function of the display screen 10 to display images. The FPC board 20 is provided with an opening 40 on a side close to the display screen 10, and the setting of the opening 40 can reduce the stress of the FPC board 20 being bound to the display screen 10, thereby avoiding obvious mura color difference in the display screen of the display screen 10, making the display effect of the display screen 10 better, thereby improving the competitiveness of the product. In addition, the FPC board 20 ages due to the passage of time, and the lateral stress on the FPC board 20 is reduced, which can extend the service life of the FPC board 20.
[0024] Specifically, see Figure 1 and Figure 2 The FPC board 20 is provided with a binding area for binding with the display screen 10, and the FPC board 20 is connected to the non-display area below the display screen 10 through the binding area. The FPC board 20 is provided with an opening 40 on a side close to the display screen 10, and the FPC board 20 is bent to a side of the display screen 10 away from the display screen, so as to reduce the size of the product, thereby making the product more compact.
[0025] Among them, see Figure 1 , the number of openings 40 is two, and the binding area includes three binding parts 30, and an opening 40 is set between every two binding parts 30, so as to further reduce the stress on the FPC board 20. Furthermore, the opening 40 is a rectangular parallelepiped structure. Further, two incisions are set at the edge of the opening 40, and the design of the incision can further reduce the extrusion stress on both sides of the binding. In addition, an FPC connecting strip is set above the opening 40, and the FPC connecting strip is used to connect the binding part 30, and the binding of the FPC board 20 can be quickly aligned through the binding part 30, thereby improving the binding efficiency.
[0026] In one embodiment, see Figure 2A heat dissipation gap 60 is provided between the FPC board 20 and the display screen 10. During operation, the display screen 10, the FPC board 20 and the working components thereon generate heat, and the heat dissipation gap 60 can conduct the heat between the FPC board 20 and the display screen 10, thereby preventing the electronic components from burning out. In order for the display screen 10 to protect the FPC board 20 from being broken by external forces, the length of the FPC board 20 is smaller than the length of the display screen 10, and the width of the FPC board 20 is smaller than the width of the display screen 10. In addition, electronic components are welded on the FPC board 20 to form a complete circuit and realize the display function of the display screen 10. Specifically, the electronic components are welded on the side of the FPC board 20 away from the liquid crystal screen, and the height of some electronic components is relatively high to prevent the higher electronic components from pressing against the display screen 10 and affecting the display effect of the display screen 10. In addition, the electronic components generate heat during operation to prevent heat from accumulating between the display screen 10 and the FPC board 20 to prevent the display screen 10 from burning out. However, the electronic components are heavy, while the FPC board 20 is soft, so a reinforcing sheet is provided on the side of the FPC board 20 close to the display screen 10, which can support the weight of the electronic components on the FPC board 20 and prevent the FPC board 20 from being uneven due to the weight. In addition, the FPC board 20 is usually connected to the housing by screws, and a small reinforcing sheet is also provided on the side of the FPC board 20 away from the display screen 10. The reinforcing sheet and the small reinforcing sheet are clamped on both sides of the FPC board 20, and screws can be inserted into the reinforcing sheet to fix the FPC board 20.
[0027] In another embodiment, the FPC board 20 is provided with an avoidance area 50, and the avoidance area 50 is used to avoid other components or the connection between other components and the display screen 10. In addition, the display screen 10 includes an upper polarizer, a lower polarizer and a liquid crystal screen. The upper polarizer and the lower polarizer are respectively attached to the upper and lower sides of the liquid crystal screen, and the upper polarizer and the lower polarizer have good light transmission performance. After the liquid crystal screen is powered on, it can display through the liquid crystal molecules therein, and the setting of the upper polarizer and the lower polarizer can filter the light that has an adverse effect on the display of the liquid crystal screen.
[0028] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
