    摘要: Methods of using a laser to separate a glass sheet is presented that employs an elongated and, preferably, asymmetrically-truncated laser beam. The methods allow glass sheets suitable for use in modern display applications to be separated at speeds up to about 200 mm/s with low levels of residual stress, e.g., levels of residual stress which are less than or equal to 100 psi, and preferably less than 50 psi. Glasses with high coefficients of thermal expansion (e.g. greater than about 35×10−7/° C.) maybe separated at faster speeds. Such low levels of residual stress translate into low levels of distortion during the manufacture of display panels (e.g., LCD panels) as well as in improved properties (geometry, strength, defect-free etc.) of the separated edges. The methods can be used with glasses of various types including glasses having high coefficients of thermal expansion and also with glass sheets of different thickness.

    摘要: A method of cutting glass that prevents uncontrolled crack propagation when high background stress is present, either in the form of thermal residual stress, external mechanical stress or a combination thereof. The method includes masking an edge of the glass by blocking the beam using highly reflective or absorptive material located near the glass surface, or deposited on the surface in a form of a thin film (or highly reflective paint) to prevent uncontrolled crack initiation and propagation starting from the glass edge. The initiation of the laser scoring is located at a predetermined distance from the glass edge. Yet another aspect of the invention embodies stopping propagation of the vent at the exiting end of the score line.

    摘要: A sheet of brittle material, such as glass, flat or bowed, is separated along a score line by applying fluid energy (compressed gas or liquid) through a fluid applicator such as a nozzle or directional fluid motivator, into a scored sheet material. A separation time of less than 1 second is possible with smooth edge quality. The brittle material can be in the form of a moving ribbon of glass sheet or a stationary sheet. A load (tension) can be applied transverse to the score line to enhance crack propagation along the score line. A controller controls the fluid pressure, release time and other process parameters for best results, depending on material properties and structure.

    摘要: Methods for separating glass sheets from glass ribbons are disclosed. One method includes forming a glass ribbon having a curvature in a lateral direction. A conformable nosing is engaged with a first surface of the glass ribbon such that the conformable nosing conforms to the curvature of the glass ribbon. The glass ribbon is scored along a scoring line on a second surface of the glass ribbon. The conformable nosing is then at least partially disengaged from the first surface of the glass ribbon by adjusting a bow of the conformable nosing. A bending moment is applied to the glass ribbon to separate a glass sheet from the glass ribbon at the scoring line. Application of the bending moment conforms the curvature of the glass ribbon to the bow of the conformable nosing prior to the glass sheet separating from the glass ribbon.
