Abstract

A new multi-luminance-level subfield method is proposed to improve the low gray scale linearity by implementing the inverse gamma relation from the gamma-corrected input signals of plasma display panel televisions (PDP-TVs). Multi-luminance levels can be expressed per sustain pulse in a low gray scale by applying the different auxiliary pulses in the same sustain-pulse subfields. As a result, this method can contribute to realize a high quality image by suppressing a low gray-level contour.
