The image shows a rotation of the director about 180° in a cholesteric phase. The corresponding distance is the half-pitch, p/2. A cholesteric liquid-crystal display (ChLCD) is a display containing a liquid crystal with a helical structure and which is therefore chiral. Cholesteric liquid crystals are also known as chiral nematic liquid ...
A blue phase mode LCD is a liquid crystal display (LCD) technology that uses highly twisted cholesteric phases in a blue phase. It was first proposed in 2007 to obtain a better display of moving images with, for example, frame rates of 100–120 Hz to improve the temporal response of LCDs. [ 1 ]
Light chain deposition disease can affect any organ. [3] Renal involvement is always present and can be identified by microscopic hematuria and proteinuria.Due to the gradual buildup of light chains from plasma filtration, renal function rapidly declines in the majority of patients with LCDD as either acute tubulointerstitial nephritis or rapidly progressing glomerulonephritis.

Early STN LCD built by Brown Boveri in 1984. In 1982, C. M. Waters and E. P. Raynes patented STN displays, [1] and by 1984 researchers at Brown Boveri (later ABB) built the first prototype STN matrix display, with 540 × 270 pixels. [2] A key challenge was finding a way to address more pixels efficiently.
A transflective liquid-crystal display [1] is a liquid-crystal display (LCD) with an optical layer that reflects and transmits light (transflective is a portmanteau of transmissive and reflective). [2] Under bright illumination (e.g. when exposed to daylight) the display acts mainly as a reflective display with the contrast being constant with ...
NGC Guideline Syntheses often provide a comparison of guidelines developed in different countries, providing insight into commonalities and differences in international health practices. An electronic forum, NGC-L for exchanging information on clinical practice guidelines, their development, implementation and use
Liquid crystals are birefringent, so applying a voltage to the cell changes the effective refractive index seen by the incident wave, and thus the phase retardation of the reflected wave. A spatial light modulator ( SLM ) is a device that can control the intensity , phase , or polarization of light in a spatially varying manner.
