Abstract
The invention discloses a liquid crystal display framework with an initiative detachment function and an initiative detachment device. The liquid crystal display framework is characterized in that shell buckles, front bracket buckles, rear bracket buckles, shell screws and bracket screws are made from shape-memory high molecular materials and are arranged on an initiative detachment driving device which can generate driving force after being heated and stimulated; and a manner of heating stimulation enables a connection relation to be invalid and parts to be separated from one another. According to the liquid crystal display framework and the initiative detachment device, the detaching time of a liquid crystal display is greatly shortened and inner parts are not damaged. The liquid crystal display framework and the initiative detachment device are particularly suitable for large-batch recycling and detachment of liquid crystal displays.
