Novel unit module for solar-powered self-driven electronic paper apparatus and method for preparing same

Abstract

The invention relates to the technical field of electronic paper apparatuses, in particular to a unit module for a self-driven organic-inorganic electro-chromic electronic paper apparatus. The unit module is characterized in that the unit module has the following structure: a lower conductive film of cathode conductive glass is provided with a square etching region; the lower conductive film outside the square etching region is provided with an energy storage film layer and a solar cell light anode in turn; the lower conductive film inside the square etching region is provided with an electro-chromic cathode; an encapsulating material is arranged in the etching region and around the lower conductive film; the anode conductive glass and cathode conductive glass are longitudinally symmetrically arranged on the encapsulating material so as to be solidified into zigzag inner and outer cavities; an electro-chromic capacitance layer and a large-grain TiO2 reflecting layer are arranged in turn below an upper conductive film of the inner cavity; a Pt film counter electrode is arranged below the upper conductive film of the outer cavity; and the inner and outer cavities are respectively provided with electro-chromic electrolyte and solar cell electrolyte. Compared with the prior art, the novel unit module has the advantages of simple technique and low cost.

Description

[technical field] [0001] The invention relates to the technical field of electronic paper devices, in particular to a unit module of a self-driven organic-inorganic novel electrochromic electronic paper device. [technical background] [0002] On the one hand, with the rapid development of information technology, in the pursuit of ultra-thin, low-power flat panel display research, electrochromic display (ECD) has low driving voltage, ultra-clear contrast, wide viewing angle and superior The memory effect has become a research hotspot for new displays, e-books, and e-newspapers. On the other hand, with the rapid increase of the world population, the demand for energy is also increasing. As a renewable energy source, solar energy has incomparable advantages over other energy sources. Solar photovoltaic cells developed in the late 20th century have been used in artificial satellites, signal lights, power supplies for field observation sites, advertising power supplies, photoele...

Problems solved by technology

The organic color-changing molecules are directly adsorbed to the surface of the conductive substrate. Although the response time can reach the order of milliseconds, it cannot be practically used in color-changing devices due to the low coloring density.
