Abstract
A dead front display is a type of display that disappears, e.g., blends with the background, when turned off. A tradeoff exists between the sharpness of the display in the ON state and the effectiveness of hiding the black state of the display behind the diffuser in the OFF state. The closer the display is to the diffuser, the sharper the ON state but the more visible the black in the OFF state. This disclosure describes a mechanism to dynamically adjust the air gap between the top diffuser layer and the display of a dead front display for different display states. When the display is turned on, the gap is reduced, producing a sharper image. When the display is turned off, the gap between the top diffuser layer and the display is increased, causing the display to be better hidden.
