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.

Samsung has developed an ultra definition (UD, or 3840×2160) resolution 82″ product for LCD TV applications. The resolution increase from full HD to UD greatly reduces 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) scheme. Viewing angle of 180 degrees, contrast ratio of 2200 to 1, and brightness of 550nits have been achieved while maintaining all other advantages of the super PVA structure.
