A second groove 5 is provided on the other surface of the backlight rubber frame 1, and an integral PCB board 6 is installed in the second groove 5. A first FPC 7 and a second FPC 8 are respectively connected to the first display screen 3 and the second display screen 4. After being bent, the first FPC 7 and the second FPC 8 are electrically connected to the PCB board 6. One PCB board 6 is used to provide control for the two display screens, and an external wiring board is connected to the PCB board 6 for connecting the PCB board 6. During installation, the backlight rubber frame 1 is fixedly installed with the shell, and the installation structure is simple and convenient.

[0033] A plurality of first material scooping grooves 9 are provided in the area of the backlight rubber frame 1 between the two first grooves 2. A second material scooping groove 10 is provided outside the second groove 5 of the backlight rubber frame 1. Both the first material scooping grooves 9 and the second material scooping grooves 10 are provided in multiple numbers and in multiple specifications, and are arranged side by side. The shape can be rectangular. The setting of the material scooping grooves can prevent the backlight rubber frame 1 from shrinking, reduce the deformation amount of the backlight rubber frame 1, avoid squeezing the internal display screen and the backlight module, and at the same time, the second material scooping groove 10 can also be used for positioning when the backlight rubber frame 1 is installed with the shell.

[0034] The two first troughs 2 and the second trough 5 are connected through a through groove 11, so that both FPCs can pass through the through groove 11 and be connected to the PCB board 6. Specifically, the through groove 11 is arranged on one side of the first trough 2.

[0036] Positioning L strips 15 are arranged at the two corners on one side of the first trough 2 where the PCB board 6 is located, and a buckle 16 is arranged on the other side of the PCB board 6. The buckle 16 presses the PCB board 6 to fix and install the PCB board 6. At the same time, in order to further stabilize the PCB board 6, components such as fixing screws are also equipped to fasten the PCB board 6 to the backlight adhesive holder 1.

[0037] The integrated dual-screen display screen provided in Embodiment 1 is further optimized. Specifically, as Figure 3 、 5 shown, the second trough 5 is filled with a heat-dissipating adhesive 17. The heat-dissipating adhesive 17 covers the components, pads and connectors on the PCB board 6, achieving effective protection for the components, connectors and pads. When encountering an impact, the heat-dissipating adhesive 17 can play a buffering role and improve the anti-collision performance, thereby realizing the high protection requirements of the display module for waterproof, anti-collision and anti-pad oxidation, improving the electrical connection stability and service life of the display module. At the same time, the heat-dissipating adhesive 17 can also improve the heat-dissipating effect, avoiding the components on the PCB board 6 from working and generating heat, which affects the service life.

[0038] The integrated dual-screen display screen provided in Embodiment 2 is further optimized. Specifically, as Figure 3 、 5As shown in the figure, after the first display screen 3 and the second display screen 4 are fixedly installed on the backlight adhesive frame 1, a protective film 18 is covered on one side surface of the backlight adhesive frame 1 where it is located in the first groove body 2. The protective film 18 is a tempered film. The protective film 18 is provided with a visible area and a non-visible area. The visible area is set to two and corresponds to the display areas of the first display screen 3 and the second display screen 4. A light-shielding ink 19 is screen-printed on one surface of the protective film 18 located in the non-visible area, which can further improve the light-shielding effect of the non-display areas of the first display screen 3 and the second display screen 4. When the screen is turned off, an integrated black effect can be achieved. And the protective film 18 is adhesively fixed to the backlight adhesive frame 1, the first display screen 3 and the second display screen 4 through a transparent adhesive layer. Of course, the protective film 18 can also be replaced with a glass cover plate.

[0039] The working principle of the integrated dual-screen display screen provided by the present utility model: After the backlight adhesive frame 1 is prepared, the PCB board 6 is fixed on the back side of the backlight adhesive frame 1. Then, the first display screen 3 and the second display screen 4 are respectively placed into the two first groove bodies 2, and the first FPC 7 and the second FPC 8 are passed through the through groove 11, bent and then welded to the PCB board 6 to complete the assembly. When functions such as improving the display effect and scratch resistance are required, a protective film 18 is adhesively bonded to the surface of the backlight adhesive frame 1. The two display screens use the same PCB board 6, realizing an integrated backlight structure for the dual screen, improving the structural strength of the dual screen. When installing, only the backlight adhesive frame 1 needs to be installed, the installation structure is simple, there will be no deviation problem, and the use of the cover plate can also be reduced, reducing the production cost and improving the market competitiveness.
