Problems solved by technology

But such a system has the following problems: a. Since the color itself comes from the material, the color switching that can be realized is extremely limited, and generally only two to three colors can be realized; b. Due to the selection of positive and negative materials, it can be used as The energy that the battery can output is limited; c. The color of the electrochromic system comes from the material, which is a pigment color, and the resolution is limited by the diffraction limit and is prone to aging and instability

Abstract

The invention provides an electrochemical system with a near-zero energy consumption display device, a preparation method and a display method. The electrochemical system comprises a first pole piece, a second pole piece and electrolyte, a conducting layer and a dielectric layer are sequentially arranged on the surface of the first pole piece in a stacked mode, and at least one through hole set is formed in the dielectric layer. In the charging and discharging process of the battery, the structural characteristics of the active material in the battery are utilized, and the active material is regulated and controlled to be orderly deposited and deembedded on the pre-designed through hole group template, so that the visible spectrum response is dynamically regulated and controlled, and a color-adjustable display device is realized; according to the invention, two functions of display and energy supply are combined into one, a self-driven display device is realized through mutual charging and discharging among different pixels, and the device integrating an electrochemical system and self-driven near-zero-energy-consumption display provides possibility for a highly-integrated ultra-small low-energy-consumption chip device in the future.

Description

technical field [0001] The invention belongs to the technical field of electrochemical systems, and in particular relates to an electrochemical system with a near-zero energy consumption display device, a preparation method and a display method. Background technique [0002] In the next generation of information technology in the future, high-performance image visualization display devices with ultra-high resolution and low energy consumption are very important. Current display devices are mainly divided into active light-emitting displays such as LCD, LED, OLED, etc., and passive reflective displays such as kindle ink screens. In addition to the pursuit of color, these displays are also moving towards ultra-high resolution and ultra-low energy. However, they are still troubled by the diffraction limit and high energy consumption. [0003] Plasmonic nanomaterials have a unique sub-wavelength light field localization that breaks through the diffraction limit, so they have ul...
