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
