Abstract

A self-powered display device includes a display module and a power module. The display module is a cholesteric liquid crystal display module, and the power module is a solar cell module. The display module allows light to enter the power module from the front side, and the power module generates electricity upon receiving the light to provide the necessary energy for the display module to show images. The power module has multiple active areas and multiple inactive areas between the active areas. When the width of the inactive area is less than or equal to 50 μm, the human eye will have difficulty discerning the width of the inactive area. Additionally, a shielding layer can be placed on the inactive area to ensure that the visual color difference (ΔE) between the inactive area and the active area does not exceed 10 color difference units, thereby improving the image quality.
