Transparent display

A transparent display, comprising:

• a self-emitting display unit,
• a first polarizing unit arranged on a viewing side of the self-emitting display unit,
• a liquid crystal module, and
• a second polarizing unit,
• wherein the liquid crystal module and the second polarizing unit are arranged on a backlight side of the self-emitting display unit, and wherein the liquid crystal module is configured to adjust a display contrast of the self-emitting display unit,
• wherein the first polarizing unit comprises a first linearly polarizing unit and a one-quarter wavelength compensating film located between the first linearly polarizing unit and the self-emitting display unit,
• wherein the second polarizing unit comprises a second linearly polarizing unit and a three-quarter wavelength compensating film,
• wherein the second linearly polarizing unit is located on a side of the liquid crystal module away from the self-emitting display unit, and
• wherein the three-quarter wavelength compensating film is located between the self-emitting display unit and the liquid crystal module and is configured to compensate an optical delay resulting from the one-quarter wavelength compensating film;
• wherein the transparent display comprises a color filter unit located between the three-quarter wavelength compensating film and the liquid crystal module.
