Manufacturing technology for smectic phase liquid crystal product

Abstract

The invention discloses a manufacturing technology for a smectic phase liquid crystal product. The manufacturing technology comprises the followings steps of preparing a first and second conductive substrates, simultaneously executing the following two steps of coating side frame glue to the first conductive substrate to prepare a sealed side frame and dipping viscosity-reduced liquid-state mixed solution into the sealed side frame in a quantitative way, and spraying gap supporting articles on the second conductive substrate and enabling the gap supporting articles to be distributed and fixed on the second conductive substrate, heating the first and second conductive substrate, counter-pointing and applying the first and second conductive substrates in a vacuumized way after the viscosity of the liquid crystal-state mixture is reduced again, solidifying the sealed side frame, and accomplishing the manufacturing of the smectic phase liquid crystal product. Realization of the method is conducted via a low-viscosity and quantitative dipping way; the technology can be precisely controlled; high production efficiency and guaranteed product quality can be achieved; and the smectic phase liquid crystal consumption is little and the product size is free of limitations.

technical field [0001] The invention relates to a manufacturing process of a smectic liquid crystal product based on low-viscosity quantitative dripping, and belongs to the field of production technology of smectic liquid crystal products. Background technique [0002] The structure of existing smectic liquid crystal products is roughly as follows figure 2 As shown, it includes first and second base layers 10 and 20 , and conductive electrode layers 30 are provided on the inner surfaces of the first and second base layers 10 and 20 . The first base layer 10 and the conductive electrode layer 30 thereon form a first conductive substrate, and the second base layer 20 and the conductive electrode layer 30 thereon form a second conductive substrate. Between the first and second conductive substrates is a mixed layer 60 obtained by mixing smectic liquid crystals and conductive additives.

AI Technical Summary

Problems solved by technology

It can be seen from the actual implementation that this heating filling process has the following disadvantages: First, since a large amount of mixed solution needs to be squeezed in from the filling port by pressure, it cannot be precisely controlled, the production efficiency is low, and the yield is limited.

Second, the consumption of smectic liquid crystals is large, resulting in serious waste

Third, the size of the product is greatly limited due to the heating process, usually only 1 hour to 20 hours of product can be produced

The high viscosity characteristics of smectic liquid crystals make it impossible to use in quantitative infusion equipment and vacuum lamination equipment operated at room temperature. The output usually needs to be controlled within 0.1mg, and such a small amount of control is impossible for high-viscosity smectic liquid crystals

In addition, on the vacuum lamination equipment at room temperature, the high-viscosity smectic liquid crystal cannot smoothly discharge the bubbles in it, and cannot smoothly diffuse and level the entire filling area.
