AI Technical Summary

Technical Problem

The external screen of existing mobile terminals has low fracture toughness and bending strength, which leads to the internal screen being easily broken after the external screen is ruptured, which increases the maintenance cost.

Method used

An anti-fall display screen is designed. By setting a transparent diaphragm between the external screen and the LCD screen, and connecting it with a rectangular frame with multiple elastic telescopic parts, the LCD screen is tightened by the elastic telescopic parts, leaving room for movement to reduce the probability of damage.

Benefits of technology

When the display drops, the external screen may be broken, but the LCD screen has room for movement through the action of the elastic telescopic member, which reduces the probability of the LCD screen being damaged, and uses a transparent diaphragm to prevent the external screen fragments from scratching the LCD screen.
