A method of finishing a laminated glass structure (102) comprising a flexible glass sheet (130) having a thickness of no greater than about 0.3 mm laminated to a non-glass substrate (116) by an adhesive layer (135) is provided. The method includes applying a compressive force against a cut edge (106) of the flexible glass sheet (130) using an abrasive surface (108) of a hand-held finishing tool (105). Material of the laminated glass structure (102) is removed at the cut edge (106) such that a glass edge strength of the flexible glass sheet (130) is at least about 50 MPa.

Various embodiments provide a substrate processing apparatus for grinding a substrate, and a display device including a substrate in which a hole is formed in an edge of the substrate using the substrate processing apparatus. The substrate processing apparatus for processing a display substrate includes a body which, in operation, rotates, a cylindrical grinding part connected to the body, and a lateral groove formed in a surface of the cylindrical grinding part. The lateral groove is configured to accommodate the display substrate. Thus, it is possible to form a hole by grinding an edge of the display substrate so as to be matched with a designed value.

An electronic grade glass substrate is provided with a recess, channel or step in one surface, and a first chamfer between the side surface of the recess, channel or step and the one surface. The side and bottom surfaces of the recess, channel or step are mirror finished, and the first chamfer is mirror finished.

A vehicular frameless interior rearview mirror assembly includes a mirror head and a mounting portion. The mirror head includes a mirror reflective element and a mirror casing. The mirror reflective element includes a glass substrate having a planar front side and a planar rear side. No portion of the mirror casing overlaps the planar front side of the glass substrate of the mirror reflective element. A camera is disposed within the mirror casing behind the mirror reflective element. With the mounting portion of the mirror assembly mounted at an in-cabin side of a windshield of a vehicle, the camera views a driver of the vehicle, and when the mirror head is moved by the driver to adjust a rearward view of the driver, the camera moves in tandem with movement of the mirror head. The camera is part of a driver monitoring system of the vehicle.
