Question

Quizplus · Accepted Answer

Plasma displays use a plasma of ionized gases to emit light, while LCDs (liquid crystal displays) use liquid crystals to control the polarization of light. Therefore, B is the correct answer. A is incorrect because both technologies can be either analog or digital. C is also incorrect because plasma displays actually produce more heat than LCDs. D is incorrect because both technologies can support various scan rates.
