Abstract
A data driving apparatus includes two data driving circuits, each including a timing controller with a clock generator and configured to receive a specific portion of data corresponding to a row of pixel in an image frame, and, after receiving the specific portion of the data, process the portion of the data; wherein the two timing controllers have different data operation times. One timing controller outputs an enable command to another one once the processing of the respective portion of the data is complete. Then, another timing controller starts to process the respective portion of the data and output an output command to the first data driving circuit in response to a finish of the processing of the second portion of the data and thereby controlling the two data driving circuits to output the processed data. An operation method thereof and a display using the same are also provided.
