Abstract

To provide a self-powered display device.SOLUTION: Provided is a self-powered display device that includes: a light-transmitting panel having a display region for transmitting light; and a photoelectric conversion module electrically connected to the light-transmitting panel and having a power generation region for absorbing the light transmitted through the display region, and converting the light into electrical energy through the power generation region to provide the electrical energy to the light-transmitting panel; wherein the light-transmitting panel is spaced apart from the photoelectric conversion module, and a projection area of the display region in the power generation region is larger than an area of the power generation region. As a result, it is possible to prevent a light shielding phenomenon from occurring in the light-transmitting panel, and to improve the power generation efficiency of the photoelectric conversion module.SELECTED DRAWING: Figure 1
