Invited Paper: World's First 240Hz TFT-LCD Technology for Full-HD LCD-TV and Its Application to 3D Display

摘要

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.
