Abstract: A device and method for eliminating an image border of electrophoretic electronic paper includes the following steps: S1, acquiring gray-scale driving waveform information and gray-scale position information, wherein the driving waveform information comprises a level value and a duration corresponding thereof; S2, outputting regulation waveform information based on an termination level value of a first gray scale, a level duration and a starting level value of a second gray scale, wherein the regulation waveform information comprises a level value, an embedding time and an embedding position of a waveform; and S3, modifying the gray-scale driving waveform information based on the regulation waveform information, and controlling an output of a drive electrode based on the modified gray-scale driving waveform information. By using the device and method, an impact of the fringe electric field on movement of electronic paper micro-capsules is eliminated, thus effectively reducing border ghosting.

Abstract: Disclosed is an electrofluidic support plate and a method for preparing the same, and an electrofluidic device comprising the support plate. The method comprises the following steps of: providing a substrate which has a surface provided with an electrode layer; arranging a first amorphous fluoropolymer layer on the surface of the substrate, and carrying out hydrophilic modification on a surface of the amorphous fluoropolymer layer; arranging pixel walls on the amorphous fluoropolymer layer after hydrophilic modification; arranging a second amorphous fluoropolymer layer which is a hydrophobic layer; the second amorphous fluoropolymer layer covering all surfaces of the pixel walls and a groove area encircled by the pixel walls; filling the groove area encircled by the pixel walls with a protective material; removing the second amorphous fluoropolymer layer not covered by the protective material and on a top of the pixel walls; and removing the protective material.

Abstract: present invention relates to a technical field of nano-silver particles, and discloses a preparation method for nano-silver particles. The preparation method includes following steps: 1) silver nitrate and water soluble stabilizer are weighed and put into a reaction vessel; 2) water is added into the reaction vessel; 3) in an illuminated environment at room temperature under atmospheric pressure, the solution in the reaction vessel is electromagnetically stirred until the solution in the reaction vessel turns red, and the nano-silver particles are formed in the solution; 4) after the reaction of the solution in the reaction vessel in step 3), the reaction vessel with the solution is kept out of light and the nano-silver particles are then extracted from the solution.

Abstract: An oil puncture controlled starting system for an EFD apparatus and manufacturing method therefor, wherein the EFD display structure comprises a base arranged below a lower electrode, and the base is provided with a step, such that a first liquid has a first thickness outside the step and a second thickness on the step, which is less than the first thickness, such a thickness difference renders the first liquid on the step to be punctured by a second liquid firstly when a lower voltage is applied between a upper electrode and the lower electrode, and the first liquid is pushed by the second liquid to move from a first area to a second area.
