Black panel effect (also known as dead front) is when the display on an electronic application appears black when it is off.
The secret to this elegant and aesthetic look is smoke coloured filters in front of the display. These filters allow the transmittance of all light (colours), and the effect can be achieved with both acrylic cover glass and polycarbonate cover glass.
However, the colour of the acrylic filter is dependent on the application, the amount of light behind the acrylic filter, and how much light passes through.
