“…Two types of OZ-IPS (type I and II) cells were fabricated, together with a conventional IPS cell for comparison. 26) Figures 2(a) and 2(b) show schematics of the OZ-IPS and the conventional IPS cells, respectively. These comprised electrode and counter substrates on which indium tin oxide (ITO) interdigital electrodes (55 nm thick; lines and spaces were 4 and 10 μm, respectively) and photo spacers were fabricated, respectively.…”

In this study, a one-side zero-azimuth anchoring in-plane switching (OZ-IPS) liquid crystal display (LCD) employing poly(n-hexyl methacrylate) (PHMA) bottlebrush polymers as an application-type zero-azimuth anchoring material was successfully developed. The twist anchoring coefficient A 2 measured for the nematic liquid crystal (NLC) on the PHMA bottlebrush at 25 °C was comparable to that of the same NLC on high-density PHMA brushes. Optimizing the optical design increased the transmission efficiency (TE) of the OZ-IPS cell with the negative NLC to 95%, which was significantly higher than that of conventional IPS cells. Using optical simulation, the OZ-IPS LCDs with a negative NLC clearly exhibited the highest TE (;107% of TN LCDs) for LCDs developed thus far. Moreover, the higher transmittance of the OZ-IPS LCDs was also confirmed for the practical TFT LCD, which exhibited a maximum luminance that was 30% higher than conventional IPS TFT LCDs.

Using a novel zero‐anchoring (ZA) interface, we have realized an ultra‐low power consumption FFS LCD with low voltage drive and higher transmittance than FFS using negative liquid crystal. In addition, we have improved the response time, image sticking and other optical performance, which have been issues for zero anchoring FFS, by developing the alignment layer materials and the optimum liquid crystal materials. It is expected to be adopted in applications requiring low power consumption in the future.
