Microcup manufacturing process based on interface modification

Abstract

The invention discloses a microcup manufacturing process based on interface modification. The microcup manufacturing process is used for solving the technical problem that local hydrophilic and hydrophobic treatment of a microcup cannot be achieved in existing microcup manufacturing. The process comprises the following steps: providing a multi-layer film structure sequentially comprising an upper protective film layer, a middle film layer and a lower protective film layer; punching the multi-layer film structure according to a preset micro-cup shape to form a micro-cup array consisting of a plurality of micro-cups on the multi-layer film structure; uncovering the lower protective film layer, and attaching the perforated multi-layer film structure to a first substrate; uncovering the upper protective film layer, carrying out hydrophilic treatment on the middle film layer, and after treatment is completed, pasting the upper protective film back to the position above the middle film layer; performing hydrophobic treatment on the combination of the multi-layer film structure and the first substrate, so that the cup wall and the cup bottom of the microcup are in a hydrophobic state; after hydrophobic treatment is completed, uncovering the upper protective film, and attaching the second substrate to the upper surface of the multi-layer film structure.

Description

technical field [0001] The invention relates to the technical field of microcup production, in particular to a microcup production process based on interface modification. Background technique [0002] At present, the microcup display has the problem of difficulty in filling ink, because the common materials are all hydrophilic materials, the ink is a system in which electrophoretic particles are dispersed in an organic solvent, and the size of the microcup is on the micron scale, so when the ink In the process of pouring into the microcup, due to the hydrophilic and oleophobic properties of the microcup material itself, the ink cannot be poured into the microcup, resulting in a poor or even impossible display. [0003] In order to allow the ink to be poured into the microcup, in the current mainstream microcup manufacturing process, mask photolithography and molding are generally used, but the above two methods often make the microcup The top of the microcup, the wall of t...
