LCDS
Examples
Chiral smectic liquid crystals are used in ferroelectric LCDs which are fast-switching binary light modulators.
Further, LCDs sometimes use a technique called dithering which is time averaging colors to get intermediate colors such as alternating between two different colors to get a color in between.
How an LCD works using an active-matrix structure New zero-power (bistable) LCDs do not require continuous refreshing.
However LCDs had blurring issues and were terrible in comparison (some still) to even 72 Hz.
In addition, the technology offers a unique path toward high-brightness full-color displays, leading to displays that are four times brighter than reflective LCDs and twice as bright as other emerging technologies.
In any case, color range is rarely discussed as a feature of the display as LCDs are designed to match the color ranges of the content that they are intended to show.
