[0039] The display layer 1 is disposed above the active device array layer 4. The first hydroelectric conversion assembly 5 is disposed between the second glass substrate 101 and the TFT (Thin Film Transistor) glass substrate 2, and on both sides of the electrode layer 102, display medium 103, and active device array layer 4. When an electrical signal passes through the electrode layer 102, it changes the state of the display medium 103, thereby displaying information. The first hydroelectric conversion assembly 5 is disposed between the second glass substrate 101 and the TFT glass substrate 2, and on both sides of the electrode layer 102, display medium 103, and active device array layer 4.

When the second hydroelectric conversion film 802 comes into contact with water, the ions in the second hydroelectric conversion film 802 undergo directionally migration under the action of water, forming an electric potential difference on both sides of the second hydroelectric conversion film 802, thereby generating current, directly converting water energy into electrical energy and outputting it; the second sealing substrate 803 is located between the second hydrophobic film 801 and the second hydroelectric conversion film 802, and the two are combined into an integral structure through the physical viscosity and chemical stability of the sealant.
