An ultra‐definition (UD or 3840 × 2160) resolution 82‐in. product with 120‐Hz high‐frame‐rate driving has been developed for LCD‐TV applications. The resolution increase from full HD to UD greatly reduces the available charging time. This problem has been overcome by employing a half‐gate two‐data‐line design (hG‐2D) for Super PVA pixels. Additionally, cost‐effective single‐bank driving has been achieved by adopting a vertical‐quarter‐partitioned (VQP) driving scheme. A viewing angle of 180°, contrast ratio of 2200:1, and brightness of 550 nits have been achieved while maintaining all of the other advantages of the Super‐PVA structure.
