1. PDP is based on the gas discharge plasma characteristics.
2. Both PDP & LCD display are very important and essential for growing engines of Korea.
3. PDP & LCD will have the same or similar picture quality, efficiency in perfomancecharacteristics to each other now .
4. Price will be main key factor for consumers to select PDP or LCD in large sized flat TV over 40.
