Liquid Crystal Display Calculators
网页Liquid Crystal Display (LCD) Calculators. Portable or pocket electronic calculators have 2 basic types of displays. One emits light, usually in some color like red, blue, green, or orange. This type of display can be a light emitting diode (LED) or some sort of tube encased display (like a fluorescent tube or Nixie tube).

How do LCDs (liquid crystal displays) work? - Explain that Stuff
网页2021年12月12日 · Like laptop computers, most 21st-century televisions have flat screens with LCDs (liquid-crystal displays) —the same technology we've been using for almost half a century in things like calculators, cellphones, and digital watches. What are they and how do they work? Let's take a closer look!
