Abstract:
The disclosure is directed to a cutting process involving: (a) creating a starter crack (41-48) using a scribe wheel, (b) application of laser or electrothermal heating, and (c) subsequent cooling from a gas or an aerosol jet, as the laser beam and cooling jet move along the desired cutting line. The cutting process can be implemented for cutting a glass panel (30) or other substrate into a plurality of smaller panels (31-35). The starter crack (41-48) may be created on any of the smaller panels (31-35) within about 10 mm to about 20 mm from the corner of the smaller panel.
Abstract:
An electroactive device can have a first conductive layer, a second conductive layer, and one or more electroactive layers sandwiched between the first and second conductive layers. One or more adjacent layers of the electroactive device may include a physical separation between a first portion and a second portion of the adjacent layers, the physical separation defining a respective tapered sidewall of each of the first and second portions. The one or more adjacent layers may include one of the first and second conductive layers. The remaining layers of the electroactive device may be formed over the physical separation of the one or more adjacent layers. The remaining layers may include the other of the first and second conductive layers.
