Abstract
Embodiments of a deadfront configured to hide a display when the display is not active are provided. The deadfront includes a substrate having a first major surface and a second major surface. The second major surface is opposite the first major surface. The deadfront also includes a neutral density filter disposed on the second major surface of the transparent substrate and an ink layer disposed on the neutral density filter. The deadfront defines at least one display region in which the deadfront transmits at least 60% of incident light and at least one non-display region 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 is not active.
