Transparent display panel and displaying method of same

A displaying method of a transparent display panel, wherein the transparent display panel comprises an organic light emitting module and a polymer dispersed liquid crystal module, the polymer dispersed liquid crystal module comprises a lower substrate and a display surface, the organic light emitting module is disposed on another side of the lower substrate, the organic light emitting module comprises a display surface, and the display surface of the organic light emitting module faces an opposite direction of the display surface of the polymer dispersed liquid crystal module, the displaying method comprises steps of:

• the organic light emitting module turning on or turning off corresponding pixels according to an image signal;
• the polymer dispersed liquid crystal module driving the polymer dispersed liquid crystal corresponding to the pixels turning on by the organic light emitting module as a scattering state;
• and
• the polymer dispersed liquid crystal module driving the polymer dispersed liquid crystal corresponding to the pixels turning off by the organic light emitting module as a transparent state.

A transparent display panel comprising:

• an organic light emitting module;
• and
• a polymer dispersed liquid crystal module, wherein the polymer dispersed liquid crystal module comprises:
• a lower substrate;
• and
• a display surface, wherein the organic light emitting module is disposed on another side of the lower substrate, the organic light emitting module comprises a display surface, wherein the display surface of the organic light emitting module faces an opposite direction of the display surface of the polymer dispersed liquid crystal module and the organic light emitting module and the polymer dispersed liquid crystal module share the lower substrate.
