We report high performance liquid crystal displays (LCDs), including fringe field switching (p-FFS) and in-plane switching (pIPS), with a small average dielectric constant (ε) but positive dielectric anisotropy material. Our low ε based p-FFS and pIPS LCDs offer several attractive properties, such as high transmittance, low operation voltage, fast response(More)
Effective rejection of time-varying clutter originating from slowly moving vessels and surrounding tissues is important for depicting hemodynamics in ultrasound color Doppler imaging (CDI). In this paper, a new adaptive clutter rejection method based on spectral analysis (ACR-SA) is presented for suppressing nonstationary clutter. In ACR-SA, tissue and flow(More)
