An electrochromic structure can include a substrate and an electrochromic residue disposed on the substrate. The electrochromic structure can include an electrochromic stack on the substrate. A process can be used to separate the structure. The process can include forming a filament in the substrate and applying a thermal treatment to the substrate. Forming a filament can be performed by applying a pulse of laser energy to the substrate. In a particular embodiment, a filament pattern including a plurality of filaments can be formed in the substrate. The substrate can include mineral glass, sapphire, aluminum oxynitride, spinel, or a transparent polymer.

In a scribing operation, first through fourth auxiliary scribe lines are formed in a glass original sheet in addition to a main scribe line extending along a preset cutting line. A cutting operation includes a straight line portion cutting operation of cutting the glass original sheet along a first straight line portion of the main scribe line and the first and second auxiliary scribe lines, and cutting the glass original sheet along a second straight line portion of the main scribe line and the third and fourth auxiliary scribe lines, and a connection portion cutting operation of cutting the glass original sheet, which has been subjected to the straight line portion cutting operation, along a first connection portion of the main scribe line, and cutting the glass original sheet along a second connection portion of the main scribe line.

The application discloses a display screen. The display screen includes a screen body including a cover glass and a substrate glass. The cover glass and the substrate glass each has a bonding surface and an outer surface opposite to the bonding surface. The outer surfaces of the cover glass and the substrate glass are provided with a cracking prevention layer at least in a peripheral region of a predetermined slotted region of the screen body. In a screen body cutting method disclosed in the application, cracking prevention layers are formed on the outer surfaces of both the cover glass and the substrate glass, so as to reduce the edge cracking or breaking of the screen body during the slotting and to reduce crack generated in the cover glass and the substrate glass, thereby improving overall strength of the screen body and increasing the yield of the product.

A method is provided for scoring glasses. The method includes the steps of generating a deep crack in the glass along an intended separation line by exerting pressure onto the glass surface using a rigid scoring tool, wherein the scoring tool, by being pressed against the glass surface and due to the advancement force while introducing the deep crack generates a zone of elastic strain in the glass in a direction along the glass surface and perpendicular to the separation line, which extends in an arc in the plane defined by the separation line perpendicular to the glass surface such that one leg of the arc is located close to the contact point of the scoring tool on the glass surface and another leg is located inside the glass. The arc being open towards the advancement/advancement direction of the scoring tool.

A method of manufacturing a glass sheet includes a start point forming step of forming a scribe line on a preset cutting portion of a glass sheet, a setting step of causing, through use of a support member having a groove-shaped recess, the support member to support the glass sheet having the scribe line formed thereon from one surface side so that the preset cutting portion is arranged on the recess, and a cutting step of generating a negative pressure in the recess to bend the preset cutting portion on the recess so that the one surface side protrudes, to thereby cut the glass sheet along the preset cutting portion with the scribe line as the start point. At the time of performing the cutting step, the entire recess is covered with a cover member from another surface side of the glass sheet through intermediation of the glass sheet.
