Abstract: The present invention provides a curved display device manufacturing method comprising the steps of: coupling a flat display, a transparent adhesive layer, and flat cover glass, thereby manufacturing a flat display assembly; applying an adhesive to the edge of the flat display assembly; seating the flat display assembly on a curved jig; adsorbing the flat display assembly onto the surface of the curved jig by using vacuum holes formed in the curved jig such that the flat display assembly is bent; and coupling a backlight unit to the adhesive-applied area. The step of coupling a backlight unit to the adhesive-applied area comprises a step of curing the adhesive in a state in which the backlight unit is forced against the display assembly such that the display assembly remains bent.

Abstract: Certain aspects pertain to methods of fabricating an optical device on a substantially transparent substrate that include a pre-deposition operation that removes a width of lower conductor layer at a distance from the outer edge of the substrate to form a pad at the outer edge. The pad and any deposited layers of the optical device may be removed in a post edge deletion operation.

The sensing element layer is located on the first substrate and includes multiple sensing elements. The second substrate is located on the sensing element layer. The micro-structure layer is located between the second substrate and the sensing element layer, and includes multiple micro-lens structures and multiple dummy structures. Orthogonal projections of the micro-lens structures on the first substrate overlap orthogonal projections of the sensing elements on the first substrate. The spacer layer is located between the second substrate and the sensing element layer, and includes multiple main spacers. Each of the main spacers covers at least one of the dummy structures.
