26.4: Novel Driving and Panel Design of Frame Inversion Method for High Aperture Ratio in the Large Size and High Resolution LCD TV Panel

The 120Hz frame inversion driving FHD LCD TV panels were fabricated without image degradations seen such as the luminance gradient and the horizontal crosstalk. The panels had the higher aperture ratio because of the wider electrode space between the pixel and common electrode than conventional S-IPS. The novel driving method of gate-low-voltage-swing was used to remove the luminance gradient and the new panel design of divided-common-feeding was adopted to suppress the horizontal crosstalk. These technologies were very successful to achieve the high aperture ratio in the S-IPS panel without increase of the panel cost.
