1. A transparent display panel, comprising a display area and a light-transmitting area;
wherein, the display area comprises a transparent substrate, an electroluminescent device positioned on one side of the transparent substrate, and a light blocking part located on a side away from the electroluminescent device, of the transparent substrate; and
the light blocking part is configured to block light entering from the side away from the electroluminescent device, of the transparent substrate to irradiate the electroluminescent device;
wherein the light blocking part comprises: a first electrode and a second electrode arranged in a stacked manner, and a first electrochromic layer located between the first electrode and the second electrode;
wherein the light-transmitting area comprises a transmission part located on a side of the transparent substrate away from the electroluminescent device, of the transparent substrate; the light transmittance of the transmission part is adjustable;
wherein the transmission part comprises a third electrode and a fourth electrode arranged in a stacked manner, and a second electrochromic layer located between the third electrode and the fourth electrode;
wherein the first electrode and the third electrode is arranged separately, and the second electrode and the fourth electrode is arranged separately.
