A source driver for driver-on-panel systems. The source driver includes a digital buffer to receive and schedule externally input digital video data, a set of shift registers to generate corresponding sampling control signals according to the data scheduled, a first set of latches to sample the scheduled data according to the sampling control signals and thus generate corresponding digital video data samples, a second set of latches to hold the samples, a set of level shifts to convert the held samples into high-voltage digital signals, a set of digital-to-analog converters to convert the high-voltage digital signals into analog signals, a set of analog buffers to drive the analog signals to a high-loading display panel, and a set of demultiplexers to output the analog signals at different times to appropriate display positions using time division multiplexing (TDM).
