Abstract: Embodiments of a deadfront (106) configured to hide a display unit in an automotive interior when the display unit is not active are provided. The deadfront (106) includes a substrate (120) having a first major surface (128) and a second major surface (126). The second major surface is opposite the first major surface. The deadfront also includes a neutral density filter (122) disposed on the second major surface (126) of the transparent substrate (120) and a colorant layer (124) disposed on the neutral density filter (122). The deadfront defines at least one display region (132) in which the deadfront transmits at least 60% of incident light and at least one non-display region (134) in which the deadfront transmits at most 5% of incident light. A contrast sensitivity between each of the at least one display region and each of the at least one non-display region is at least 15 when the display unit is not active.
