Self-powered display device

A self-powered display device, comprising:

• a substrate having a display region and a non-display region;
• a first photoelectric conversion unit disposed on the substrate and located in the display region;
• a light-transmitting display module stacked on the first photoelectric conversion unit and configured to receive a first light, wherein the first light penetrates the light-transmitting display module and enters the first photoelectric conversion unit, and the first photoelectric conversion unit converts the first light into a first electrical energy and provides the first electrical energy to the light-transmitting display module;
• and
• a wireless charging module disposed on the substrate and located in the non-display region, wherein the wireless charging module is configured to receive a second light and converts the second light into a second electrical energy, and the wireless charging module provides the second electrical energy to the light-transmitting display module;
• wherein a wavelength range of the first light is different from a wavelength range of the second light;
• wherein the wavelength range of the first light is between 400 nm and 700 nm, and the wavelength range of the second light is between 700 nm and 2500 nm.
