Abstract: A digital-analog conversion circuit, a method for the digital-analog conversion and a source driver are disclosed. A digital-analog conversion circuit may include a latch for storing N bit digital data therein, and a digital-analog converter, for performing a first digital-analog conversion on predetermined bits out of the N bit data stored in the latch by using R-string conversion, and for performing a second digital-analog conversion based on a result of the first digital-analog conversion and all remaining bits of the N bit data, excluding the predetermined bits.

Abstract: A source driver in a display may include a latch capable of latching input data received from a timing controller in a display, a delta-sigma digital-to-analog converter configured to convert the input data stored in the latch to an analog signal by delta-sigma modulation, and an output buffer configured to output a column drive signal by buffering the analog signal received from the delta-sigma digital-to-analog converter. Accordingly, a source driver in a display modulates input data of 10-bit or higher by delta-sigma modulation with high accuracy, and then converts the data to an analog signal. Therefore, although an area occupied by the source driver of embodiments becomes smaller than that occupied by the related art source driver with a high resolution of 10-bits or higher, a display panel can provide an image of high resolution.
