Display module

A display module for absorbing a light source, comprising:

• a first substrate;
• a transparent type solar cell, located on a surface of the first substrate relative to an incident direction of the light source for absorbing and converting the light source into electric power, wherein the transparent type solar cell comprises a first transparent electrode layer, a photoelectric conversion layer, and a second transparent electrode layer, and the photoelectric conversion layer substantially covers an entirety of the first substrate, wherein a visible light transmittance of the transparent type solar cell is 10%-40%, and a color temperature (Tc) of the transparent type solar cell is greater than 2400K;
• a display device, located on a surface of the transparent type solar cell relative to the incident direction of the light source;
• a second substrate, located on a surface of the display device relative to the incident direction of the light source;
• an electric power storage device, connected to the transparent type solar cell for storing the electric power;
• a driving circuit, connected to the display device for driving the display device;
• and
• a power supply transfer switch, for switching the electric power to one of the electric power storage device and the driving circuit.
