Unlike the dry-spaghetti-rigid-straight molecules in Kevlar's liquid crystal, LCDs use boomerang-shaped molecules.

与凯夫拉尔液晶体中的干意大利面硬直分子不同，液晶显示器使用回旋镖形状的分子。

Thanks for watching this episode of SciShow, which was brought to you by LCDs, but also by our patrons on Patreon.

The Liquid Crystal Displays, or LCDs, that we use today are quite a different technology.

我们今天使用的液晶显示器或 LCD 是一种截然不同的技术。

The essential feature of LCDs is that the pixels in them switch between amorphous and crystal-like phases, which changes their optical properties.

LCD的基本特征是其像素在非晶相和类晶相间转化，因此改变其光学性质。

In the 1980s, the displays changed from LEDs to LCDs, and the calculators got thinner, solar-powered, and some no larger than a credit card.

到20世纪80年代，显示屏从 LED 变为 LCD，计算器变得更薄了，可以太阳能供电，有些甚至和信用卡差不多大。
