Abstract
A transparent display apparatus including a backlight module, a display panel, and a switching panel is provided. The backlight module includes a light source and a light guide plate (LGP). The display panel is located on a light emitting surface of the LGP. The switching panel and the backlight module are located at the same side of the display panel. The switching panel includes a first substrate, a second substrate opposite to the first substrate, a polymer-dispersed liquid crystal layer located between the first substrate and the second substrate, a first electrode layer located between the first substrate and the polymer-dispersed liquid crystal layer, and a second electrode layer located between the polymer-dispersed liquid crystal layer and the second substrate. The first electrode layer is divided into first electrode patterns that are separated from and electrically independent from one another. Another transparent display apparatus is also provided.
