Abstract:
The present invention provides a transparent displaying apparatus, which includes a transparent display (30/40) and a liquid crystal twisting layer (20) arranged on a back surface of the transparent display (30/40). The liquid crystal twisting layer (20) includes therein liquid crystal molecules that selectively exhibit two states of arrangement including a first one of being substantially perpendicular to the transparent display (30/40) and a second one of being substantially parallel to the transparent display (30/40). When the liquid crystal molecules of the liquid crystal twisting layer (20) are arranged perpendicular to the transparent display (30/40), the liquid crystal twisting layer (20) is in a transparent state, such that a viewer may see, on a display screen of the transparent display (30/40), background scenery on the backside of the transparent displaying apparatus; and when the liquid crystal molecules of the liquid crystal twisting layer (20) are arranged parallel to the transparent display (30/40), the liquid crystal twisting layer (20) is in a non-transparent state, such that a viewer does not see, on the display screen of the transparent display (30/40), the background scenery on the backside of the transparent displaying apparatus and, compared to the transparent state of the liquid crystal twisting layer (20), the display screen of the transparent display (30/40) in this state shows relatively high displaying contrast, providing a better effect of displaying.
