This publication describes techniques and apparatuses for increasing camera performance and improving the aesthetic appearance of electronic device display screens with front facing cameras that utilize display screen blind-holes. The techniques include depositing a black material on metal signal traces (metal traces) located in an inactive area of the display screen. The black material is positioned to increase the viewable area of the front-facing camera, reduce the size of the inactive area (e.g., a display screen blind spot), hide reflective metal traces present on a layer of the display panel, and reduce the occurrence of the lightguide effect on image quality.
