The preparation process of the second conductive fiber 20 comprises the following steps: the polymer wire substrate is coated with a layer of transparent electrode material using a dip coating method to form a second transparent electrode layer covering the polymer wire substrate, thereby preparing the second conductive fiber 20.
It should be noted that the display provided by the present invention is a light emitting color changing fabric, and the plurality of first conductive fibers 10 and the plurality of second conductive fibers 20 are arranged in a crossing manner to form a warp and weft lap joint, and after an ac voltage is applied to the plurality of first conductive fibers 10 and the plurality of second conductive fibers 20, respectively, electrons and holes are transmitted at the crossing of the first transparent electrode layer and the second transparent electrode layer, respectively, so as to form a light emitting spot in an electroluminescent layer in a composite manner, thereby serving as a sub-pixel. Through the selection of the electroluminescent material, the construction of the sub-pixels with various colors is realized, and the luminous color-changing fabric can be obtained by weaving the second conductive fibers 20 and the first conductive fibers 10 through weaving, knitting and other textile methods.
It can be understood that the conductive fiber in the prior art adopts fiber yarn as a substrate, and due to the rough surface of the fiber yarn, the film forming performance and the process method of the conductive film layer and the luminous film layer are limited, the manufacturing cost is very high, the problems of non-uniform light emission, joule heat and the like are easily caused, and the fiber yarn has a limited service life and is easy to deform at high temperature or washing.

In one embodiment, the shape of the polymer wire-like base is any one of circular, elliptical, rectangular, and square in a direction perpendicular to the extending direction of the first conductive fiber 10 or the second conductive fiber 20. Namely, the first substrate and the second substrate are integrally any one of a circular line body, an elliptical line body, a rectangular line body and a square line body. When the first substrate and the second substrate are rectangular lines as a whole, the light emitting area of the sub-pixels can be increased. Specifically, the first substrate and the second substrate are arranged into the rectangular line body, so that the size of the sub-pixels of the display is increased, the occupation ratio of a blank area of the pixels is reduced, and the display effect can be optimized.
In one embodiment, the width of the polymer wire-like substrate in a direction perpendicular to the extending direction of the first conductive fibers 10 or the second conductive fibers 20 is greater than or equal to 5 micrometers and less than or equal to 500 micrometers.

The zinc oxide has large energy band gap and exciton binding energy, high transparency and excellent normal temperature luminescence property. The zinc oxide films prepared under different process conditions have different performances, and the zinc oxide transparent conductive film has light transmittance of more than 90% in a visible light range of 100-800 nm. About 2 percent of alumina film is doped in the process of preparing the zinc oxide film, the resistance of each square can be controlled below 100 ohm, and the light transmittance is unchanged.
