[0027] To further understand the content, characteristics and effects of the present utility model, the following embodiments are exemplified and described in detail with reference to the drawings as follows:

[0028] Such as Figure 1 、 Figure 2 And Figure 3As shown in the figure, a display screen assembly provided by the present utility model includes a display panel 1, a first light-shielding film 2, a backlight panel 3 and a second light-shielding film 4. The first light-shielding film 2 is disposed on the back of the display panel 1. The backlight panel 3 is disposed on a surface of the first light-shielding film 2 away from the display panel 1. The second light-shielding film 4 is disposed on a surface of the backlight panel 3 away from the first light-shielding film 2. Two protruding strips 31 are provided on a surface of the backlight panel 3 away from the first light-shielding film 2. The two protruding strips 31 are respectively located on both sides of the second light-shielding film 4, and the thicknesses of the two protruding strips 31 are both greater than the thickness of the second light-shielding film 4.

[0029] By providing two protruding strips 31 on a surface of the backlight panel 3 away from the first light-shielding film 2 and making the thickness of the protruding strips 31 greater than the thickness of the second light-shielding film 4, when the plugging device presses down to suck the display screen assembly located in the upper layer in the tray, the two protruding strips 31 can play a supporting role, so that the adhesive between the backlight panel 3 and the second light-shielding film 4 will not overflow from the periphery of the backlight panel and the periphery of the light-shielding film due to the downward pressure of the plugging device, avoiding the overflowing adhesive from lifting the display screen assembly in the lower layer adjacent to the display screen assembly in the upper layer.

[0030] In some preferred embodiments, the two protruding strips 31 are respectively located on both sides of the second light-shielding film 4 in its length direction. In specific applications, by respectively disposing the two protruding strips 31 on both sides of the second light-shielding film 4 in its length direction, compared with respectively disposing the two protruding strips 31 on both sides of the second light-shielding film 4 in its width direction, materials can be saved and the production cost can be reduced. Specifically, the two protruding strips 31 and the backlight panel 3 are integrally formed.

[0031] In some preferred embodiments, one end of the second light-shielding film 4 abuts against one of the two protruding strips 31, and the other end of the second light-shielding film 4 abuts or does not abut against the other of the two protruding strips 31. In specific applications, by designing one end of the second light-shielding film 4 to abut against one of the two protruding strips 31, the protruding strip can play a limiting role on the second light-shielding film 4, so that the second light-shielding film 4 can be accurately pasted at a predetermined position on the backlight panel 3.

[0032] In some preferred embodiments, a through hole 32 is provided on the backlight panel 3, and the through hole 32 is located between the two protruding strips 31 or on one side of the two protruding strips 31. In specific applications, there are lamp beads on the PCB board. When the display screen assembly is plugged into the PCB board, one end of the lamp bead away from the PCB board extends into the through hole 32. In this way, not only can the plugged PCB board be thinner and lighter, but also the light emitted by the lamp bead can be fully irradiated on the display panel 1 through the backlight panel 3, enabling the display panel 1 to display better.

[0033] In some preferred embodiments, the above-mentioned through hole 32 is located between two ribs 31, and the through hole 32 is adjacent to one of the two ribs 31. Through the above technical solution, the through hole 32 is located at one end of the backlight panel, so that the light emitted by the lamp beads on the PCB board is transmitted from one end to the central area of the display panel 1 through the backlight panel 3, which can not only ensure sufficient light quantity, but also use fewer lamp beads to save production costs.

[0034] In some preferred embodiments, the lengths of the above-mentioned first light-shielding film 2 and the backlight panel 3 are both greater than the length of the display panel 1. In specific applications, by designing the lengths of the first light-shielding film 2 and the backlight panel 3 to be greater than the length of the display panel 1, there is sufficient light on the back of the display panel 1 to irradiate it to ensure a good display effect.

[0035] In some preferred embodiments, a barrier film 5 is wound around the side wall of the above-mentioned backlight panel 3. In specific applications, by winding the barrier film 5 around the side wall of the backlight panel 3, it is possible to prevent the light from diffusing and being lost from the side wall of the backlight panel 3, further ensuring that there is sufficient light on the back of the display panel 1 to irradiate it, and further improving the display effect.

[0036] In some preferred embodiments, the above-mentioned display panel 1 includes a display screen 11 and a plurality of pins 12, and the plurality of pins 12 are arranged in a "one" shape at the edge of the display screen 11. Specifically, a clamping position 121 is provided at one end of each pin 12, and the clamping position 121 is clamped to the edge of the display screen 11. By providing the clamping position 121 at one end of the pin 12, the display screen 11 can be firmly connected to the pin 12.

[0037] In summary, the display screen assembly of the present invention sets two ribs on the surface of the backlight panel away from the first light-shielding film, and designs the thickness of the ribs to be greater than the thickness of the second light-shielding film, so that when the plugging device is pressed down, it is not easy for the adhesive to overflow from the periphery of the backlight panel and the periphery of the second light-shielding film. Therefore, when the display screen assemblies are stacked on top of each other in the tray, the upper display screen assembly is not easy to lift the lower display screen assembly by adhesion, so as to ensure normal plugging of the plugging device.

[0038] The above is only the embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
