Abstract

The invention belongs to the technical field of displayer structures, solves the technical problems that in the prior art, a microcapsule film layer has no transformation possibility, and the stretchability of hydrogel is reduced after the hydrogel loses water, and provides a stretchable microcapsule film for reflective display and a preparation method thereof. The stretchable microcapsule film comprises a transparent electrode layer, a display film layer and a stretchable driving backboard which are tightly bonded from top to bottom in sequence, and the display film layer comprises hydrophilic light resin and microcapsules evenly distributed in the hydrophilic light resin; the transparent electrode layer comprises a first hydrophobic light resin layer and a nanowire film which is semi-embedded into the first hydrophobic light resin layer, the stretchable driving backboard comprises an elastic substrate made of a second hydrophobic light resin layer and a driving circuit, and the driving circuit is constructed on the elastic substrate and has a stretchable structure. The stretchable microcapsule film for reflective display and the preparation method have the advantages that the microcapsule film layer has the possibility of transformation, and the stretchability of the hydrogel is not affected after the hydrogel loses water.

Description

technical field [0001] The invention relates to the technical field of display structures, in particular to a stretchable microcapsule film for reflective display and a preparation method. Background technique [0002] Microencapsulated electrophoretic display is the most mature commercial reflective display technology, and its products are widely used in e-readers, trademarks, and billboards. In addition, microencapsulated cholesteric liquid crystals can also be used as the display film layer of reflective displays, and are applied to electronic products such as electronic drawing boards and billboards. Realizing a stretchable reflective display can further broaden the application field of this type of display technology, make the reflective display truly foldable and crease-free like paper, and further obtain new features of elastic stretchability. In the natural state, stretchable displays have obvious wrinkled structures, but this affects the effect and aesthetics of th...
