Abstract
The present invention discloses a method for scribing and breaking a glass substrate and related device. The method includes: scribing the glass substrate to form a scribing notch; making a transmission medium of supersonic waves contact the scribing notch; transmitting supersonic waves to the scribing notch via the transmission medium to break the scribed glass substrate under an effect of supersonic waves. The present invention adjusts the frequency of the supersonic waves to make the frequency close to the natural frequency of the scribing notch such that they resonate together. Therefore, the resonation force is uniformly applied on all scribing notch. Therefore, this resonation force can break the scribed glass substrate along the scribing notch beautifully without any damages on the scribing notch and terminals.
