[0002] A liquid crystal display screen, a type of flat panel display, is a display type used in digital clocks and many portable computers. LCD displays use two sheets of polarizing material, with a liquid crystal solution between them. When an electric current passes through the liquid, the crystals realign so that light cannot pass through them. Thus, each crystal acts like a shutter, allowing light to pass through or blocking it.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides a double - sided liquid crystal display screen as shown in Figures 1 to 6 and includes:

[0026] Two sets of opposite single - sided display screen assemblies 1, and the single - sided display screen assembly 1 includes a frame 101 and a liquid crystal display panel 102 embedded inside the frame 101;

[0027] The support column 2 is located between two groups of single-sided display components 1. A support box 3 is fixed to the top of the support column 2. A rotating shaft 4 is rotatably connected to the inner cavity of the support box 3 through a bearing. A sleeve 5 is rotatably connected to the outside of the rotating shaft 4 through a bearing. Connecting plates 6 are fixed to the outside of both the rotating shaft 4 and the sleeve 5. The connecting plates 6 are respectively fixedly connected to the tops of the two groups of single-sided display components 1. Driven bevel gears 7 are fixed to the outside of both the rotating shaft 4 and the sleeve. A driving motor 8 is arranged in the inner cavity of the support box 3. A driving bevel gear 10 is fixed to the output shaft of the driving motor 8. The driving bevel gear 10 meshes with the driven bevel gears 7 respectively. An adjusting component 9 for displacing the driving motor 8 is arranged in the inner cavity of the support box 3;

[0028] By adjusting the position of the driving motor 8 through the adjusting component 9, it is convenient to drive the driving bevel gear 10 to separately mesh with the two groups of driven bevel gears 7 by the driving motor 8. Subsequently, the rotating shaft 4 and the sleeve are independently driven, so that one side of the single-sided display component 1 is flipped from above to above the other single-sided display component 1, increasing the area of the display screen. At the same time, the orientation of the spliced display screen can be selected, which is convenient for use when the display area needs to be increased.

[0029] The adjusting component 9 includes a movable box 91. The driving motor 8 is installed in the inner cavity of the movable box 91. An electric push rod 92 is fixed in the inner cavity of the support box 3. The piston rod of the electric push rod 92 is fixed to the side of the movable box 91. By installing the driving motor 8 in the movable box 91, it is convenient to drive the movable box 91 to move by the electric push rod 92 to adjust the position of the driving motor 8, so that the driving bevel gear 10 meshes with the two groups of driven bevel gears 7 separately.

[0030] A chute 11 is opened in the inner cavity of the support box 3. A slider 12 is slidably connected to the inner cavity of the chute 11. The slider 12 penetrates through the chute 11 and is fixed to the outside of the movable box 91. By sliding the slider 12 in the chute 11, it is convenient to limit the movable box 91, ensuring that the driving bevel gear 10 can accurately mesh with the driven bevel gear 7 after moving the position.

[0031] A limiting groove 13 is opened at the top of the frame 101. After the connecting plate 6 is flipped, it is clamped with the limiting groove 13. Through the setting of the limiting groove 13, not only can it prevent the connecting plate 6 from contacting the top of the frame 101 after flipping, making it impossible for the flipped single-sided display component 1 to perfectly fit with the other group of single-sided display components 1, but also it is convenient to clamp and limit the two groups of single-sided display components 1, improving the stability of the spliced display screen.

[0032] A receiving hole 14 is formed on the outer side of the support column 2. A support spring 15 is fixed in the inner cavity of the receiving hole 14. The movable end of the support spring 15 is fixed with a buffer column 16. One end of the buffer column 16 penetrates to the outer side of the support column 2 and fits against the outer side of the frame 101. The buffer column 16 is supported by the support spring 15, which facilitates shock absorption and buffering of the single-sided display screen assembly 1 and prevents the single-sided display screen assembly 1 from colliding with the support column 2.

[0033] An installation plate 17 with an installation hole is fixed at the bottom of the support column 2. A support block 18 is fixed on the top of the installation plate 17. The opposite sides of the support block 18 are fixed to the outer side of the support column 2. The installation plate 17 facilitates the installation and fixation of the support column 2, and then the support block 18 increases the stability of the support column 2 and the single-sided display screen assembly 1.

[0034] During specific use, after the support column 2 is installed through the installation plate 17, under normal circumstances, the two single-sided display screen assemblies 1 are located on both sides of the support box 3. When it is necessary to increase the display area on one side, the electric push rod 92 is started. Then, the electric push rod 92 drives the movable box 91 to slide in the support box 3 along the chute 11 direction. Subsequently, the movable box 91 drives the drive motor 8 and the drive bevel gear 10 to engage with a set of driven bevel gears 7. Then, the drive bevel gear 10 drives the rotating shaft 4 or the sleeve alone through the driven bevel gear 7. Then, the rotating shaft 4 or the sleeve drives one side of the single-sided display screen assembly 1 to flip upward through the connecting plate 6. Subsequently, it flips to the upper side of the other single-sided display screen assembly 1 and is clamped with the connecting plate 6 through the limit groove 13, so that the two single-sided display screen assemblies 1 are spliced to increase the display area.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
