P-119: A Novel Image Quality Improvement Technology by Charge Pumping Method

We propose a new LCD mode named as Charge-Pumped Super Patterned Vertical Alignment (CP S-PVA) which can utilize 1G-1D driving. In this mode, the voltage difference between two sub-pixels is controlled by a unique charge-pumped structure. This results in equal level of off-axis image quality and transmittance to TT S-PVA. Moreover, this new mode has good production yield and production margin. Operation schemes and display performance of CP S-PVA are presented.
