Abstract

The invention belongs to the technical field of textile chemical fibers, and particularly relates to electronic fabric with a display function and a preparation method thereof. The electronic fabric comprises warp-wise electroluminescent display fibers and weft-wise transparent conductive fibers, wherein the warp-wise electroluminescent display fiber sequentially comprises a flexible conductive fiber, an electroluminescent display active layer and a resin protective layer from inside to outside. The preparation method comprises the following steps: loading a display active material on the surface of the flexible conductive fiber to obtain an electroluminescent display fiber; dip-coating a transparent insulating packaging layer outside the electroluminescent display fiber; and weaving the electronic fabric with the display function by using the plurality of insulating electroluminescent display fibers as warp, and using the transparent conductive fibers as weft in a plain weaving mode. Through the design of a control circuit, matrix display of the fabric in a specific mode is realized. The brightness of pixel points can reach 200-500 cd / m<2>, and the service life is 1000-3000 h; and the fabric has excellent flexibility and air permeability, and still keeps stable after being bent for 1000 times.

Description

technical field [0001] The invention belongs to the technical field of textile and chemical fibers, and in particular relates to an electronic fabric with a display function and a preparation method thereof. Background technique [0002] As a new generation of electronic devices, wearable devices have attracted extensive attention from the scientific and industrial circles. At present, wearable display devices are mostly thin-film planar, and its planar structure is difficult to adapt to complex deformations such as twisting, collision, scratching or tearing during application, and its airtight structure cannot meet large-area wearable requirements. Electronic fabrics provide infinite possibilities for the digitalization of our daily life. The construction of electronic fabrics is based on a series of functional fibers through weaving. The electronic fabric with display function is formed by warp and weft knitting of electrodisplay fibers and conductive fibers to form elect...
