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 tra...

Zusammenfassung: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.
