[0002] An LCD screen is a display device that uses liquid crystal technology to display images and other visual information. Liquid crystal is a material state between solid and liquid that can adjust light to produce images. An LCD screen is composed of many tiny liquid crystal units, each of which can control the brightness of the light source behind it, thereby forming various patterns and texts on the screen. Existing LCD screens are generally equipped with an angle adjustment bracket. An angle adjustment bracket is a supporting device that can adjust the angle of a monitor or other device. This bracket is usually connected to the bottom of the monitor and fixed to a desktop or wall, allowing users to adjust the angle of the screen according to their height, posture or personal preference.

[0003] The existing angle adjustment bracket is widely used, but the existing angle adjustment bracket will wear out after being used for too long. The existing angle adjustment bracket is usually an integrated production design, which is not convenient to disassemble. The existing angle adjustment bracket can usually be adjusted in height, but the positioning of the display screen is not firm enough, resulting in the display screen may drop after being used for too long. Therefore, in view of the above problems, a liquid crystal display screen with a built-in angle adjustment bracket is proposed. Utility Model Content
