On the rear glass the data electrode is mounted.
The dielectric is coated on the rear glass.
Red, Green and Blue colour phosphors are formed on the data
electrode with the ribs. However to improve colour reproduction
and brightness, each colour phosphors are formed different
width This is called " Asymmetrical cell " as Panasonic original
technology.
