Abstract

The invention relates to materials of an electronic paper micro-cup manufactured on a flexible or rigid substrate and a method for preparing the electronic paper micro-cup. In part by weight, the raw materials of the electronic paper micro-cup comprise 10 to 30 parts of solvents, 15 to 40 parts of resin, 3 to 6 parts of active components, 20 to 70 parts of glass filler and 1 to 4 parts of dispersant; and the coatings can further comprise 1 to 2 parts of defoamer dimethyl polysiloxane in part by weight. The method for preparing the electronic paper micro-cup comprises 1) a base material pretreating process, 2) a coating process, 3) a prebaking process, 4) a masking and exposing process, 5) a developing process and 6) a solidifying process. The method can manufacture a micro-cup figure withhigh resolution, also can simplify the manufacturing processes and reduce the preparation cost of the micro-cup, and is quite suitable for the manufacturing of the electronic paper micro-cup.

Description

technical field [0001] The invention relates to a material for making an electronic paper microcup on a flexible or rigid substrate and a preparation method thereof, in particular to a photolithographic microcup material that is resistant to strong soluble solvents such as tetrachlorethylene and is closely bonded to the substrate and its use Preparation. Background technique [0002] Electrophoretic display (Electrophoretic, E-Paper) is referred to as electronic paper. Compared with other display technologies, electrophoretic technology has the characteristics of low energy consumption, high daylight readability, low production cost, and is suitable for flexible display technology. Because its technology combines the advantages of ordinary paper and electronic displays, it has become the most likely technology to realize the industrialization of electronic paper. [0003] The basic principle of electrophoretic display is that in a small area (microcapsule or microcup), unde...
