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.

摘要:
The invention relates to a method for manufacturing color filters utilizing a color electrodeposition coating which contains an anionic electrodeposition resin having a low acid value. Said method comprises coating a layer of positive photoresist onto a transparent electrically conductive substrate, exposing the substrate under a photomask or photomasks to form regions of different initial levels of exposure energy, exposing the entire surface of the substrate through an energy-incrementing way to, progressively, allow all regions of the substrate to achieve an energy sufficient to completely expose the photoresist on each corresponding region, developing stepwise each region with a same developer solution to cause the electrically conductive substrate of the corresponding region uncovered, electrodepositing said region with a color electrodeposition coating containing an anionic electrodeposition resin having a low acid value to finish the pixel arrangements of the desired colors and completely exposing the substrate. The low acid value anionic electrodeposition resin utilized in the invention has an acid value of 1 to 70 mg KOH/g. The method of the invention shows the advantages of having a high degree of freedom in pattern figures and a wide process window. Moreover, the manufacture color filters of large surface and the perfect yield rate of products are possible.

An improved method is disclosed for making color filters via electrodeposition or lithographic electrodeposition of a plurality of colored resins onto an electrically conductive substrate. The method comprises the steps of: (a) forming a black-hued pattern on the substrate; (b) dividing the substrate into an intended zone and a conjugate zone, the intended zone being portions of the substrate to be deposited with the colored resins and the conjugate zone being portions of the substrate not to be deposited with the colored resins; (c) forming a permanent insulation film on the conjugate zone of the substrate; and (d) electrodepositing the colored resins onto the intended zone of the substrate. The photosensitive insulation resin is preferably a negative photosensitive resin containing: (i) a resin binder containing a carboxyl (COOH) group; (ii) 1-15 wt %, based on the weight of the resin binder, of a photopolymerization initiator; and (iii) 30-100 wt %, based on the weight of the resin binder, of a photo-reactive monomer or oligomer each containing at least two unsaturated double bonds.
