a display material and method and device thereof are provided . the display material is first formed by evenly mixing appropriate weight ratios of dflcs , incurable nanoparticles , curable nanoparticles , and a photoinitiator . next , the evenly mixed mixture is disposed between two parallel conducting transparent substrates , wherein an electrical field is conducted thereto and the dflcs therein aligned to the direction of the applied electrical field . concurrently , under the applied electrical field , some curable nanoparticles within the evenly mixed mixture , form short nano chains , initiating the photo initiator . the frame structure of short nano chains stabilize both the clear and scattering states , thereby the bistable characteristic was improved and the contrast ratio was enhanced as applied to bistable displays .
