The invention provides a tray for packaging LCD assemblies, which includes a bottom plate. The bottom plate is provided with a plurality of rhombic grooves which are arranged side by side, and a plurality of discharge grooves for buffering stress concentration are arranged around the rhombic grooves. Because the bottom plate of the tray of the invention is designed with various types of stress concentration factors which are mutually associated, and the rhombic grooves of the stress concentration factors form a plurality of stress concentration zones on the bottom plate of the tray, the stress concentration in the center of the bottom plate can be effectively decreased. In addition, the discharge grooves are arranged around the rhombic grooves in the invention, and the stress concentration of the rhombic grooves is decreased by the discharge grooves. By the design of the aforementioned stress concentration factors, the stress and strain in the center of the bottom plate of the tray can be decreased, thereby preventing the tray from deforming largely because of excessive stress concentration to damage the LCD assemblies. |
