Mirror Glass incorporates a special optical coating which, when combined with any LCD or LED screen, transforms the display into a mirror.The screen works on the balance of light between the outside of the glass (the mirror side) and the inside (the screen). When light on the mirror side is brighter than the inside – i.e., when the screen is switched off – the glass looks like a standard mirror. When light on the inside is brighter – when the screen is switched on – the image can be seen clearly through the mirror glass.
