มีรังสี UV บ้างแต่น้อยกว่า CRT เยอะ อย่างไรควรดูระยะ 1.5 เมตรขึ้นไปดีที่สุดครับ แล้วแต่ขนาดจอภาพ ดูไกล้ๆ มันร้อนนะครับ อิอิ
Misconception #7: Plasma TVs give off a lot of radiation.
This rumor just might be the most outlandish of the bunch, especially considering the fact that the monitor you're reading this on -- assuming it is a CRT -- gives off considerably more radiation than a plasma display ever could. While plasma monitors do generate a tiny amount of ultraviolet (UV) radiation, it is essentially negligible because this radiation extends no more than an inch outward from the screen. Because individual pixels are illuminated, the radiation is "contained" to the pixels themselves. This is not the case with tube-based TVs, which utilize an electron gun that shoots radiated light toward the screen in order to illuminate phosphors thereon. This projects small amounts of radiation sometimes more than 12" outward from the screen. Not to worry: Both plasmas and CRTs comply with Food and Drug Administration (FDA) guidelines for TV radiation emissions, which have been in place since 1969.
ข้อดีของ Plasma TV
Plasma panels have some advantages over digital rear-projection displays and LCD flat panel TVs:
The viewing angle is wider than LCD flat panels and even most digital rear-projectors.
Black levels are generally quite good, though not quite as good as CRTs.
All other things equal, plasma displays offer better color fidelity than LCD flat panels, and better edge-to-edge accuracy than CRT displays.
Plasma panels offer a faster response time than LCD TVs, so image ghosting is far less prevalent.
