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.
