The doctor blade type thin film applicator is a tool and technique for uniformly applying liquid or slurry materials in a thin layer onto a substrate. It is relatively simple yet highly versatile, widely used in various laboratories and industrial settings for creating coatings and thin films. It is equipped with a stainless steel hot plate with a vacuum suction function for placing the substrate. Temperature settings are made using a digital PID controller on the front panel. The film thickness is adjusted by using a micrometer to set the gap between the substrate and the doctor blade. The slurry is dropped onto the substrate, and the blade can be moved horizontally simply by pressing a button using the built-in electric moving stage. The speed and movement amount are set using a knob on the front panel and are displayed digitally on an LED display.

In liquid crystal compositions used for TVs, mobile phones, and PCs, alkyl liquid crystals are employed to improve response speed. However, with the increase in display brightness, the degradation due to the photochemical reactions of alkyl liquid crystals has come under scrutiny, and light stabilizers have been used to maintain high reliability. Nevertheless, there are issues where light stabilizers cannot be used in PDLC and PSLC, which involve radical reactions, and there is a demand for non-alkylation in spatial light modulators that require adaptation to higher brightness, although this results in slower response speeds. Additionally, there are problems such as a narrower liquid crystal temperature range, making it unsuitable for automotive applications. Therefore, we developed non-alkyl liquid crystals to solve these issues, filed patents in the United States, China, the EU, Taiwan, South Korea, and Japan, and secured rights. We have already begun incorporating them into automotive applications and have started expanding into high-brightness LCOS and others.
