Description

Technical Field

[0001] The utility model relates to the field of displays, in particular to a reinforced liquid crystal display screen. Background Art

[0002] In recent years, liquid crystal displays have been widely used in different fields. However, since liquid crystal displays themselves have inherent deficiencies in terms of vibration resistance, impact resistance, high and low temperature, salt spray, and high humidity environments, a series of measures need to be taken to improve the performance of liquid crystal displays. This usually refers to adding one or more layers of protective material to the LCD screen to form a reinforced display screen to enhance its durability and impact resistance. This type of screen is usually used in environments that require higher durability and safety, such as industrial control, outdoor display, military equipment and other fields.

[0003] Traditional reinforced LCD screens usually have edge reinforcement frames around the LCD screen body and anti-fall mechanisms at the four corners of the front and back of the screen so that the LCD screen body can be protected from damage when it falls to the ground, thus achieving an effect of taking both internal and external factors into consideration.

[0004] However, the existing reinforced LCD screen is generally modified directly on the LCD screen body, and is relatively fixed to prevent it from falling. Therefore, it is impossible to conveniently take out the LCD screen for maintenance and repair to improve the efficiency of later maintenance. Utility Model Content
