Abstract

The invention relates to a 3D manufacturing method for an electrode of an in-plane switching blue phase liquid crystal display device. The electrode may go deep into the blue phase liquid crystal to reduce a driving voltage. By way of layered manufacturing, the method comprises the steps: (1) designing a three-dimensional digital model; (2) performing an approximating process on the three-dimensional digital model to eliminate an irregular free surface, and converting the model into an STL format that can be accepted and operated by a 3D printer; (3) hierarchically slicing the model into a series of two-dimensional cross-sectional graphs; (4) preparing electrode printing paste; (5) printing the electrode by a 3D printing apparatus, and performing 3D molding on materials by curing or hardening; (6) performing a subsequent process on the printed electrode to form a desired electrode of the in-plane switching blue phase liquid crystal display device. The 3D manufacturing method, with great manufacturing flexibility, effectively reduces the complexity in and the cost of manufacturing the electrode of the in-plane switching blue phase liquid crystal display device.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to a 3D manufacturing method for an electrode of a coplanar switching blue-phase liquid crystal display device. Background technique [0002] Compared with ordinary liquid crystals, blue-phase liquid crystals have the following four advantages: (1) No alignment film is required, which not only reduces process complexity but also reduces costs when applied to display technology; (2) The response time is at the sub-millisecond level, and the application In display technology, it can reduce the blurring of dynamic images caused by response time in traditional liquid crystal displays, and it is possible to realize sequential display without using color filters, which not only reduces process complexity and cost, but also improves light transmittance; (3) The black state of the blue phase liquid crystal display is optically isotropic, so the viewing angle of the blue phase is...
