Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screens, in particular to an adjustable touch liquid crystal display screen. Background Art

[0002] LCD may not be a new term for many users, but the history of this technology may be far beyond our imagination. As early as the end of the 19th century, Austrian botanists discovered liquid crystals, that is, liquid crystals, that is, a substance that has both the fluidity of liquid and certain arrangement characteristics similar to crystals. Under the action of an electric field, the arrangement of liquid crystal molecules will change. This affects its optical properties, and this phenomenon is called the electro-optical effect. Using the electro-optical effect of liquid crystals, British scientists created the first liquid crystal display, or LCD, in the 20th century. Today's liquid crystal displays widely use fixed-line liquid crystals. If we look at it microscopically, we will find that it looks like a cotton swab. Compared with traditional CRTs, LCDs are not only small in size, thin in thickness, light in weight, low in energy consumption, low in operating voltage, and have no radiation, no flicker, and can be directly matched with CMOS integrated circuits. Due to its many advantages, LCDs have entered the field of desktop applications since 1998, and liquid crystal displays have also developed touch screens.

[0003] However, the existing touch LCD display has the following disadvantages:

[0004] (1) The existing touch LCD screen has a weak angle adjustment function. When in use, the traditional LCD screen has a single angle and is difficult to adjust. Users watch from different positions, which causes the device to have limitations and is not conducive to use;

[0005] (2) The existing touch screen LCD screen has a weak screen cleaning function. When the device is used for a long time, a layer of impurities will adhere to the screen surface. If it is not removed in time, the device efficiency will be reduced and the touch screen sensitivity will be reduced. Utility Model Content

When the screen surface is difficult to use, the support rod 11 is pulled back and forth, and the limit slider 10 limits the support rod 11 when the support rod 11 moves, and the support rod 11 moves to drive the cleaning plate 12 to clean the screen surface, and remove impurities such as fingerprints on the screen, thereby achieving the effect of improving the use efficiency of the device, and avoiding the situation that a layer of impurities will adhere to the screen surface after the device is used for a long time. The lifting plate 14 can be adjusted to a certain height by pulling the lifting plate 14, and the fixing frame 13 can limit the lifting plate 14. After the lifting plate 14 is pulled to a certain height, the block 16 will be stuck in the circular slot 19 due to the tension of the spring 15, so that the block 16 is fixed and difficult to loosen and fall off. The device is supported and fixed by the setting of the tripod 17, and the anti-skid pad 18 is anti-skid, and the effect of improving the placement stability of the device is achieved through the connection with the tripod 17. When the block 16 is stuck in the circular slot 19, the circular slot 19 limits the block 16 to prevent the block 16 from loosening and falling off. The setting of the connecting groove can limit the connecting slider 20 when the connecting slider 20 slides to prevent the position of the connecting slider 20 from shifting. When the limit slider 10 moves, it drives the connecting slider 20 to slide in the connecting slot 21.
