Electrochromic element, photochromic glass and transparent display screen

Abstract

The invention relates to an electrochromic element, photochromic glass and a transparent display screen. The electrochromic element comprises a first substrate assembly, wherein the first substrate assembly comprises a first transparent substrate and a first transparent electrode layer arranged on the first transparent substrate; a second substrate assembly which comprises a second transparent substrate and a second transparent electrode layer arranged on the second transparent substrate; an electrochromic layer which is arranged between the first transparent electrode layer and the second transparent electrode layer; and a first conductive layer including a plurality of first conductive lines disposed on the first transparent electrode layer. Due to the fact that the first conductive lines are distributed on the first transparent electrode layer, current can be rapidly conducted to all the areas of the first transparent electrode layer,so that the electrochemical reaction degree of all the areas of the electrochromic layer is more synchronous, and then the electrochromic layer changes color more evenly.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to an electrochromic element, a color-changing glass, and a transparent display screen. Background technique [0002] Electrochromism means that under the action of an applied voltage or current, the optical properties (such as light transmittance, light reflectance or light absorbance) of the electrochromic layer in the visible light wave range can produce stable and reversible changes, thereby being able to show colors. and changes in transparency. Electrochromic technology can be applied to a variety of products, such as energy-saving windows, automotive glass, car mirrors or display screens, etc. [0003] However, the traditional electrochromic element has the defect of uneven discoloration, especially for products with a large discoloration area. Contents of the invention [0004] Based on this, it is necessary to provide an electrochromic element, a color-changi...
