The Ultra high Definition (3840times2160) resolution, 70″ LCD TV with 240Hz frame rate has been developed. A cost effective single bank driving architecture with multi‐chip structure is realized by adopting a vertical quarter partitioned (VQP) and overlap data exchange (ODX) driving scheme. Even though half‐gate two‐data line design (hG‐2D) is adopted to overcome the charging time limitation, scan line overlapping driving scheme has also been implemented to enhance the actual pixel charging performance. The 240Hz frame rate driving technology makes 3‐dimensional display through temporal division such as 3D display of active shutter glass possible. Furthermore, a novel up‐scaling algorithm with inventive single‐frame super‐resolution methodologies has been invented to cope with input display data of FHD resolution.
