In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

Please refer to FIG. 1 , FIG. 2 and FIG. 3 , the utility model provides an LCD display screen assembly, including a display panel 1 , a first polarizer 2 , a backlight plate 3 and a second polarizer 4 .

The first polarizer 2 is arranged on the back of the display panel 1. The backlight plate 3 is arranged on the side of the first polarizer 2 away from the display panel 1. The second polarizer 4 is arranged on the side of the backlight plate 3 away from the first polarizer 2. The projection of the backlight plate 3 in the thickness direction is smaller than the projection of the second polarizer 4 in the thickness direction, so that a blocking area 5 is formed between the periphery of the backlight plate 3 and the second polarizer 4.

By designing the projection of the backlight panel 3 in its thickness direction to be smaller than the projection of the second polarizer 4 in its thickness direction, a blocking area 5 is formed between the four sides of the backlight panel 3 and the second polarizer 4, so that the blocking area 5 can block the adhesive overflowing from the four sides of the backlight panel 3, so that the adhesive is not easy to overflow from the four sides of the second polarizer 4.

4 , in some preferred embodiments, the width W of the blocking area 5 is 2-5 mm. By designing the width W of the blocking area 5 to be 2-5 mm, it is possible to effectively block the adhesive overflowing from the periphery of the backlight plate 3 without affecting the illumination of the backlight plate 3 and the reflection of the second polarizer 4.

In some preferred embodiments, the projection of the backlight plate 3 in the thickness direction is smaller than the projection of the first polarizer 2 in the thickness direction. In specific applications, by designing the projection of the backlight plate 3 in the thickness direction to be smaller than the projection of the first polarizer 2 in the thickness direction, the first polarizer 2 can improve the visual effect well, so that the display panel 1 can better perform imaging.

In some preferred embodiments, the projection of the first polarizer 2 in the thickness direction coincides with the projection of the second polarizer 4 in the thickness direction. In specific applications, the projection of the first polarizer 2 in the thickness direction is designed to coincide with the projection of the second polarizer 4 in the thickness direction, that is, the first polarizer 2 and the second polarizer 4 are designed to be the same in size and shape, which is convenient for production and processing.

In some preferred embodiments, the backlight plate 3 is provided with a countersunk hole 31, and the second polarizer 4 is provided with a through hole 41, and the through hole 41 is connected to the countersunk hole 31. In a specific application, a lamp bead is provided on the PCB board, and when the LCD display assembly is plugged into the PCB board, the end of the lamp bead away from the PCB board passes through the through hole 41 and is located in the countersunk hole 31, so that not only the plugged PCB board can be made thinner, but also the light emitted by the lamp bead can be fully irradiated on the display panel 1 through the backlight plate 3, so that the display panel 1 can display better.

In some preferred embodiments, the countersunk hole 31 is provided at one end of the backlight plate 3, and the through hole 41 is provided at one end of the second polarizer 4. In specific applications, by providing the countersunk hole 31 and the through hole 41 at one end of the backlight plate 3 and one end of the second polarizer 4, respectively, the light emitted by the lamp beads is transmitted from one end to the central area of the display panel 1 through the backlight plate 3, which can ensure sufficient light and use fewer lamp beads to save production costs.

In some preferred embodiments, the countersunk hole 31 and the through hole 41 are both square. In specific applications, by designing the countersunk hole 31 and the through hole 41 to be square, it is easy to process and produce.

In some preferred embodiments, the lengths of the first polarizer 2, the backlight plate 3, and the second polarizer 4 are all greater than the length of the display panel 1. In specific applications, by designing the lengths of the first polarizer 2, the backlight plate 3, and the second polarizer 4 to be greater than the length of the display panel 1, the back of the display panel 1 is illuminated by sufficient light to ensure a good display effect.

In some preferred embodiments, the display panel 1 includes a liquid crystal screen 11 and a plurality of pins 12, and the plurality of pins 12 are sequentially arranged at the edge of the liquid crystal screen 11. Specifically, a clamping position 121 is arranged at one end of the pin 12, and the edge of the liquid crystal screen 11 is clamped at the clamping position 121. By providing the clamping position 121 at one end of the pin 12, the liquid crystal screen 11 can be firmly connected to the pin 12.

In summary, the LCD display screen assembly of the present invention is designed to have a projection of the backlight panel 3 in its thickness direction that is smaller than the projection of the second polarizer 4 in its thickness direction, so that a barrier area 5 is formed around the backlight panel 3 and between the second polarizer 4, so that the barrier area 5 can block the adhesive overflowing from the edge of the backlight panel 3 to avoid adhesive overflow, and further, when multiple LCD display screen assemblies are stacked up and down in a tray, the adhesive of the upper LCD display screen assembly is not easy to stick to and lift the lower LCD display screen assembly, so as to ensure normal insertion.
