(CNTs-PBP). This flat plasma panel has unique properties which are low power
consumptions, high luminous efficiency, simple production process and low prime cost.
Firstly we used the indium-tin-oxide (ITO) glasses as the substrate of the front and the
rear panel. The ITO film is used for the electrodes in the light panel. The phosphor
powder which was visible light excited and mixed with the commercial binder (BP-55),
then screen printed on the ITO-glass substrates. In this process, we added some CNTs in
the phosphor powder. This is the key point about the low breakdown voltage of the
plasma generation. After fabricated the panel, we measured the luminance intensity,
chromaticity diagram, current and voltage characteristics, emission light spectrum and the
Paschen’s behavior of the device. Furthermore we optimized the luminance of the device
with different methods such as adding a reflection layer behind the rear panel, mixing
helium gas into the argon plasma and driven the prototype panel by pulse voltage. In the
conclusion, the device has a good luminance 550 cd/m2(nits) and a low power
consumption 1.4 W. And we also attempt this approach in a study-commercial 14-inch
AC- PBP which fabricated in Chunghwa Picture Tubes, LTD. (CPT) while the present of
the CNTs that increased almost 20% of the luminous efficiency at the commercial
luminance intensity standard (10,000 cd/m2) of the backlight panel.
