Abstract Materials and components for IPS (in‐plane switching) ‐TFT‐LCDS are optimized based on a basic analysis of the in‐plane switching behavior of nematic liquid crystals. We have newly developed materials and components accessible for mass producible and commercially available IPS‐TFT‐LCDS. New phenomena unlike from that found ...

... director at the bounding substrates. By using the in-plane switching (IPS) of the LC which is achieved by an in-plane electric field, the driving voltage was confirmed to be far less than that of the conventional IPS mode in which both substrates possess strong anchoring characteristics. Moreover, because of the absence of strong subsurface director deformations, the cell could operate optically in the Mauguin regime. Using these features we propose a new type of LC switching mode - in-plane sliding (IPSL) mode. We have realized this mode ...

We demonstrated fast in-plane switching (IPS) of negative liquid crystals by using crossed patterned electrodes. Switching to the bright state can be achieved by applying an in-plane field using the bottom patterned electrodes, whereas switching to the dark state can be obtained by applying an in-plane field using the top patterned electrodes. We obtained, experimentally, turn-off switching that was four times faster than that of the conventional IPS mode.

The performance of a reflective in-plane switching (IPS) liquid crystal display is simulated by the parameter space method. The IPS electrodes and reflectors can be separately fabricated on the top and bottom substrates. The normally black reflective in-plane switching display shows wide viewing angle, high contrast ratio, weak color dispersion, and fast response time.

... as a wide viewing angle unlike the conventional in-plane switching (IPS) mode display. The device shows unique electro-optic behavior, nevertheless the liquid crystal director rotates almost in-plane as in the IPS mode. We found that light efficiency decreases as the rubbing angle with respect to the horizontal component of the fringe field decreases for a liquid crystal with positive dielectric anisotropy, whereas this is not observed for a device driven by the in-plane field. In this paper, the switching mechanism and voltage-dependent transmittance characteristics with respect ...

In this paper, we propose an in-plane switching (IPS) mode for liquid crystal displays (LCDs) that, in principle, is free of retardation of the LC cell. Basically, the optical configuration of the LC cell consists of an A-plate and an LC layer for switching between the dark and bright states. We could achieve a fast response time compared with the conventional in-plane LC cell because the free retardation condition of ... transmissive mode. Experiments for verification of the proposed in-plane switching LC cells have shown a significant reduction of the rising time and falling time simultaneously due to the small cell gap. Furthermore, we also proposed an optical configuration for wide viewing property of the retardation free IPS LCD by applying the optical films. We proved ...

Abstract In-plane switching (IPS) of liquid crystals showed advantageous voltage-holding ratio (VHR) characteristics so that liquid crystals with low resistivity could provide higher VHRs compared with the twisted nematic effect. This experimental result was obtained when electric fields were applied approximately parallel to the substrate plane using the IPS electro-optical effect. We found that the in-plane electric field generates supplementary capacities which support retention of an externally applied voltage over the liquid crystal layer during ...
