and faster refresh rate displays, the nextgeneration TVs and gaming monitors are expected to accommodate 8K resolution with a refresh rate of 120Hz and beyond. In such display systems, about one thousand channels will be integrated on a source driver IC (SD-IC), one-horizontal line (1-H) time will be reduced to under 1.8μs, and the total data throughput of the interface between timing controller (TCON) and SD-ICs will surpass 190Gb/s. This will result in deterioration of display quality due to the channel offset, insufficient channel settling time, and bandwidth limitation of intra-panel interface [1-5]. As shown in Fig. 26.1.1, three key solutions for: (1) large deviation of root-mean-square voltage output (DVRMS), (2)
