- 4How is Lithium-ion different from Lithium-ion Polymer?
-
It depends on the state of the electrolyte (liquid/ polymer) which makes the Lithium ions transfer.
Lithium-ion usually adopts aluminum cans to sustain the flammable active materials of the battery securely since it includes liquid state electrolyte; while Lithium Polymer uses Polymer state electrolyte which is more stable than Lithium-ion electrolyte and covers the external parts with Laminated film.
- 3Is a fuel cell an environmentally friendly energy source?
-
Electricity occurs by reaction between hydrogen and oxygen. At this, water is produced as reactant and it is not harmful to the earth environment.
- 2(High Definition) Is the screen quality of PDP better than that of CRT?
-
Definition itself is not a direct technical factor to cause difference in screen quality of CRT or PDP. Screen quality involves numerous items as well as definition. When definition only is considered, based on currently commercialized products, CRT method is more liable to produce higher definition products. (Surely, for special monitors)
For general TV PDP and CRT have the same method. But, when it comes to that HD broadcasting of coming digital era in a full scale, CRT that will transform digital HD broadcasting into analogue again can be disadvantageous concerning noise. On the other hand, PDP can express digital signals on the large screen as it is, so viewers can entertain reality and high screen quality. In addition, same PDPs can differ their definition in accordance with product groups. Usually PDP is divided into SD and HD so called. SD is appropriate to general TV broadcasting method and HD is more appropriate to HD broadcasting method.
- 1What is 6 Sigma?
-
Sigma refers to standard deviation in Greek and various measurement values indicating variation. In other words, 6 Sigma is process capability to produce good products within 6 times the standard deviation centered on the mean in a normal distribution. Simply speaking, 6 Sigma means the process capability to produce less than 3.4 defects when 1 million products were produced. (Namely, 99.99966% good quality)
