A full‐HD (FHD) liquid crystal display TV (LCD‐TV) has been enhanced by increasing the panel's frame rate to 240Hz, and this 240Hz driving technology has been applied to 3D TV. Compared to a 120Hz LCD, the 240Hz LCD has two challenges: 1) half of the available pixel charging time, and 2) three times as many interpolated frames. A new architecture has doubled the available pixel charging time by means of a half‐gate two‐data (hG‐2D) driving scheme and a charge‐shared super PVA (CS S‐PVA) pixel structure. Additionally, a 240Hz ME/MC algorithm has been implemented on the LCD module to convert 60Hz incoming frames into 240Hz frames. Motion picture response time (MPRT) of the new LCD‐TV has been measured as 4.7msec, which is similar to the MPRT for a cathode ray tube (CRT) TV.

A novel driving method employing 2-dimensional spatial averaging is proposed. This method successfully eliminates the vertical line artifact caused by luminance difference from unbalanced polarity. This spatial averaging method can secure charging time, minimize driver heating, and achieve higher display quality.

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 announced the development of a full WUXGA (1920×1080) 57″ LCD‐TV panel using Super PVA (S‐PVA) technology, the world's largest LCD‐TV. This product represents several breakthrough developments, which include contrast ratio of over 1000:1, and response time of sub‐10msec using DCC‐II technology. In addition, Samsung has overcome some major obstacles toward production of such large‐sized panels.
