Abstract

Electronic devices such as handheld electronic devices may have display modules. The display modules may be covered with a layer of protective cover glass. Peripheral portions of the cover glass may be coated with an opaque masking layer to block interior portions of the device from view. An opening in the opaque masking layer can be formed over an active portion of the display module. To facilitate alignment of the display module active area with the opening in the cover glass masking layer, the display module may be provided with alignment marks. The alignment marks may be formed in opposing corners at an end of the display module. The alignment marks may be formed from metal structures on one of the glass layers in the display module. An opaque masking layer that blocks stray backlight may have openings that are formed over the metal structures.
