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.

A method of symmetrically chamfering a substrate includes repeating, at least a plurality of times, the steps of chamfering an edge of the substrate using a chamfering wheel, measuring an asymmetric chamfering deviation (y) of the edge of the substrate which is chamfered, and controlling a relative position of the chamfering wheel with respect to the substrate by a value of a function f(y) of the variable y. It is possible to constantly symmetrically chamfer the edge of the substrate via active response to a change in the chamfering environment without a hardware-based operation of the related art.

A vehicular interior rearview mirror assembly includes a mounting structure and a mirror head adjustable about the mounting structure. The mirror head accommodates a mirror reflective element comprising a glass substrate. With the vehicular interior rearview mirror assembly mounted at an interior portion of a vehicle, the mirror head is adjustable about the mounting structure by a driver of the vehicle to adjust the driver's rearward view. The glass substrate includes a periphery surface extending between a planar first surface and a planar second surface and spanning the thickness dimension of the glass substrate. The planar first surface faces the driver of the vehicle. No part of the mirror casing encroaches onto the planar first surface of the glass substrate. The mirror head accommodates a video device for internal cabin surveillance, and wherein the internal cabin surveillance includes detection of drowsiness of the driver of the vehicle.

A method of producing a liquid crystal panel includes a grinding process and a sealing process. The grinding process includes grinding at least one common liquid crystal panel including a liquid crystal layer, a pair of boards that sandwich the liquid crystal layer, and a frame-shaped sealing member sandwiched between the boards along the non-rectangular outline to remove a section of the sealing member and to leave a rest of the sealing member. The grinding process further includers forming a sealing member removed processed edge section of the common liquid crystal pane. The sealing member removed processed edge section includes edges of the boards corresponding to the section of the sealing member removed from the common liquid crystal panel. The sealing process includes applying a sealing resin to the sealing member removed processed edge section to fill a space between the edges of the board.
