It is the important factor that data line reduction with high aperture ratio for low cost pane fabricatol. In the high resolution panel such as WUXGA (1920×RGB ×1200 pixels), it is hard to apply data D‐IC reduction (DDR) structure because of charging time insufficiency. In this paper, we have proposed a new driving method in WUXGA panel. This dual data and common (DDC) structure reduces D‐ICs by the reduction of data line 30% compared to conventional one. Transmittance ratio has been increased about 7% by using the DDC structure. The new structure was fabricated as same the normal 4mask amorphous silicon process with integrated gate driver (GIP). Through reliability test it showed same image quality compared to conventional one and we could verify new pixel panel's stability.
