Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and in particular to a display screen module and a liquid crystal display screen. Background Art

[0002] Liquid crystal display is a flat-panel display that uses the electro-optical effect of liquid crystal materials to display images. It is mainly composed of two parallel glass substrates with liquid crystals filled in the middle. It refracts light by controlling the arrangement of liquid crystal molecules through electric current, thereby displaying images. Liquid crystal display is widely used in indoor and outdoor advertising, transportation, sports, exhibitions, performances, rentals and gatherings.

[0003] At present, some LCD screens used in advertisements are in a relatively fixed state and have a relatively simple form of publicity. When the advertising cost is low, using a larger screen for publicity is not only prone to high power consumption and large space occupation, which will affect the subsequent profit return, but also the publicity method of the screen with a relatively fixed state is relatively simple. If the staff uses pictures and texts for publicity, it is necessary to install an advertising board on the wall next to the screen. This process is time-consuming and labor-intensive, and the advertising board is also prone to damage when installed with nails. In addition, since some LCD screens are currently flat, pedestrians need to stand at a certain angle to observe the advertising information. Therefore, this type of publicity method has certain limitations and the communication effect is relatively poor. Summary of the invention

[0004] The purpose of the present invention is to provide a display screen module and a liquid crystal display screen. The present invention can adjust the state of the display screen according to the publicity cost and the walking direction of pedestrians at the publicity location, so as to increase the practicality of the display screen when in use and increase the publicity effect of the display screen. In addition, the staff can also place the graphic advertising board inside the storage slot to improve the flexibility of the display screen when in use, thereby solving the problem that some existing display screens have a relatively fixed state when in use, which is inconvenient to adjust according to the publicity cost and the required publicity effect, and the publicity form is relatively single.

[0042] Working principle: The staff will first install the display on the wall, and then the staff can adjust the status of the display as needed. When the publicity cost is low, the staff can adjust the display to Figure 1 In the state shown, the first liquid crystal display screen 4 and the second liquid crystal display screen 23 are used independently. The first liquid crystal display screen 4 can be used for the main publicity work. The staff can place the publicity board inside the storage slot 33 so as to carry out publicity through pictures and texts. During this process, the staff can turn off the second liquid crystal display screen 23 to save power resources and ensure costs. When the publicity cost investment is high and a large publicity page is required, the staff can start the motor 71, and the driving shaft 72 drives the inner cam 73 and the outer cam 74 to rotate, and the positioning plate 101 enters the interior of the rectangular groove 9. At the same time, the driving shaft 72 drives the gear ring 25 to rotate, and the gear plate 26 moves to push the second vertical plates 22 on both sides so that the second vertical plates 22 can be adjusted to a tilted state. At this time, the rotation of the inner cam 73 can assist in driving the second vertical plates 22 to adjust to Figure 2 In the state shown, the second liquid crystal display screen 23 is used in conjunction with the first liquid crystal display screen 4 so as to increase the length of the advertisement and thereby enhance the advertisement effect. At the same time, the pressure rod 14 moves through the connecting mechanism 11 and drives the piston plate 132 to squeeze the air inside the air storage box 131. The squeezed air is injected into the cavity 16 through the air pipe 15. The movable plate 171 drives the protective frame 30 to move accordingly. The protective frame 30 can protect the side of the second liquid crystal display screen 23 to increase the aesthetics of the display screen when in use and ensure the safety of the display screen when in use. More preferably, the staff can adjust the display screen to Figure 1 In the state shown, the second liquid crystal display screens 23 on both sides are used to promote different advertisements, thereby improving the flexibility of the display screen when in use.
