Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, specifically to a liquid crystal display with an anti-glare structure. Background Technology

[0002] Liquid crystal displays (LCDs) are a type of flat-panel display that uses a liquid crystal solution in two polarizing materials. When an electric current passes through the liquid, the crystals rearrange to achieve image formation. Liquid crystal is an organic compound composed of long, rod-shaped molecules. In its natural state, the long axes of these molecules are roughly parallel. When light travels along the alignment of the molecules, it is twisted as it passes through the liquid crystal. When a voltage is applied to the liquid crystal, the molecules rearrange, allowing light to travel in a straight line without twisting. LCDs are widely used in various electronic devices, such as calculators, electronic watches, mobile phone screens, medical instruments, and digital camera screens.

[0003] Chinese Patent Publication No. CN116386479A, authorized on July 4, 2023, discloses a liquid crystal display screen with an anti-glare structure. This display screen includes a base, a fixed seat fixedly connected to the left end of the base, a T-shaped component fixedly connected to the top axis of the base, a movable seat fixedly connected to the top of the T-shaped component, a display frame movably connected to the top of the movable seat, and one end of a support rod fixedly connected to the bottom of the inner wall of the display frame. In this anti-glare liquid crystal display screen, after the auxiliary plate moves to a designated position, the serrated groove, in conjunction with the telescopic rod and spring in the telescopic block, exerts downward pressure on the vertical rod. The vertical rod drives the roller to press down, achieving the positioning function of the auxiliary plate. This ensures that the auxiliary plate regains its locking position after being pushed back by the T-shaped component, preventing accidental activation of the compensation device due to user touch of the auxiliary plate and improving the stability of the device.

[0004] Existing LCD screens lack LCD technology, and prolonged staring at them can cause eye fatigue, affect vision, reduce screen performance, and fail to meet user needs. Utility Model Content

[0030] Working principle: When the motor 6 is turned on, the take-up roller 12 rotates counterclockwise. As the take-up roller 12 rotates, the anti-glare film 4 is released. The slider 8 increases the weight at the lower end of the anti-glare film 4. The released anti-glare film 4 falls down under the action of gravity. The fallen anti-glare film 4 forms an anti-glare structural layer in front of the LCD screen 2. When the motor 6 is turned on, the take-up roller 12 rotates clockwise. As the take-up roller 12 rotates, the anti-glare film 4 is wound up. The silicone ring 15 removes dust from the surface of the anti-glare film 4.
