Self-powered display device

A self-powered display device, comprising:

• a cholesteric liquid crystal display module, comprising a front side and a rear side, wherein the front side is a display surface;
• a solar cell module, positioned on the rear side of the cholesteric liquid crystal display module and electrically connected to the cholesteric liquid crystal display module, and comprising a plurality of the solar cell sheets and a plurality of the busbars positioned between the solar cell sheets;
• and
• a shielding layer, corresponding to and disposed on the surface of the busbars;
• wherein the visual color difference between the shielding layer and the solar cell sheets remains within the range of 10 color difference units.

A self-powered display device, comprising:

• a display module, comprising a front side and a rear side, wherein the front side is a display surface;
• a power module, positioned on the rear side of the display module and electrically connected to the display module, and comprising multiple active and inactive surfaces distributed alternately, wherein each active surface comprises and corresponds to an electrode layer;
• and
• a shielding layer, disposed on the inactive surface, wherein a visual color difference (ΔE) between the shielding layer and the active surface is within a maximum of 10 color difference units.
