Abstract

The invention discloses an electrochromic display device and a manufacturing method thereof. The electrochromic display device comprises a first base plate, a second base plate and an electrochromic fluid filled between the first base plate and the second base plate. Each of the first base plate and the second base plate comprises a substrate and a pixel electrode layer. The first base plate is provided with a plurality of grooves, and the electrochromic fluid is filled in the grooves isolately. Since the electrochromic fluid is filled in the grooves arranged on the first base plate and isolated in the grooves of each pixel area, crosstalk between adjacent pixels can be avoided, and performance of the electrochromic display device is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an electrochromic display device and a manufacturing method thereof. Background technique [0002] Electrochromism refers to the phenomenon that the optical properties of materials (reflectivity, transmittance, absorptivity, etc.) undergo stable and reversible color changes under the action of an external electric field, which is manifested as reversible changes in color and transparency in appearance. Fluids with electrochromic properties are called electrochromic fluids, and devices made of electrochromic fluids are called electrochromic devices. Compared with other displays, electrochromic display devices have the advantages of no blind angle, high contrast, low manufacturing cost, wide operating temperature range, low driving voltage, rich colors, etc., and are widely used in instrument display, outdoor advertising, static display and other fields. [0003] figure 1 It is ...
