[0002] A liquid crystal display (LCD) is an active-matrix liquid crystal display driven by thin-film transistors. It mainly uses electric current to stimulate liquid crystal molecules to produce dots, lines, and surfaces, which, together with backlight tubes, form an image. IPS, TFT, and SLCD are all subcategories of LCD.

[0003] The current publication number CN205546321U discloses a liquid crystal display (LCD) comprising a front display assembly and a rear cover connected to the display assembly at the rear. An aluminum foil is attached to the front surface of the rear cover. By employing the above technical solution, this LCD enhances the strength of the central area of ​​the rear cover by adding aluminum foil, reducing the amount of deformation under pressure. This allows the rear cover to meet the deformation standard, thus providing better protection for the LCD.

[0004] To address the issues associated with LCD screens, existing technology involves adding aluminum foil to the back cover to enhance its strength in the center, thus providing better protection for the LCD screen. However, this approach still results in complex wiring and inconvenient cable management. Utility Model Content
