A timing controller including a memory unit configured to store image data with respect to p*q sub-pixels defined using p numbers of data lines and q numbers of gate lines, a reception unit configured to receive, from a host, (n+m)-bit image data with respect to each of two or more of the sub-pixels, a controller configured to generate pseudo control data corresponding to m-bit image data of the two or more of the sub-pixels, and an output unit configured to output n-bit image data with respect to each of the sub-pixels to a digital unit of a data driving unit, and output the pseudo control data to an analog unit of the data driving unit.

Timing controller generating pseudo control data included in control packet and N-bit image data included in RGB packet

Provided is a data driver, a driving method of the data driver, and a display device. The data driver includes a latch unit configured to store n-bit image data, wherein n&#x2265;2; a conversion unit configured to convert N-bit digital data including the n-bit image data and variable m-bit pseudo control data into an analog voltage and then output the analog voltage, wherein m&#x2265;1; and an output unit configured to output a data voltage based on the analog voltage. The data driver is capable of supplying a high image quality based on N-bit digital data with a small circuit size that is based on n-bit image data.
