Abstract
Embodiments of this disclosure pertains to methods for controlling adhesive bondline while cold-bending a glass substrate. The method includes forming a frame to define a viewing area at least partially surrounded by the frame; shaping the frame to include at least one curvature; positioning a spacer proximate the frame, the spacer comprising: a border area; and a protrusion extending from the border area; engaging the border area of the spacer with the frame to insert the protrusion through the viewing area, wherein the protrusion extends beyond the frame a first distance; positioning an adhesive between the frame and the glass substrate alongside the protrusion to control the bondline; engaging a glass substrate with the adhesive and the protrusion to cold form the glass substrate to the shape of the frame; and securing the glass substrate to the spacer to hold the frame against the adhesive to maintain the bondline.
