AbstractThis paper proposes a line‐time optimization (LTO) technology for ultra‐large and high‐resolution liquid crystal display (LCD) televisions. Line‐time optimization enables a single‐bank data driver configuration without severe image degradation. When the proposed method is applied to an ultra‐high‐definition (UHD) LCD with a single‐bank data driver scheme, the LCD performance comparable to that of a dual‐bank data driver method can be obtained. The implementation of the proposed method helps in achieving desirable goals such as a reduction in the number of drivers and realization of a much more flexible design of UHD LCDs.
