Abstract
Provided are a data driver and a display driving circuit including the data driver. A data driver configured to drive a display panel including a plurality of subpixels connected to a plurality of sensing lines includes: a plurality of sample-and-hold circuits configured to perform a sampling operation on a plurality of sensing signals received via the plurality of sensing lines; a switching block configured to provide a first sensing signal among the plurality of sensing signals to a first sample-and-hold circuit in a first sensing period, and in a second sensing period, provide the first sensing signal to a second sample-and-hold circuit not being adjacent to the first sample-and-hold circuit in a second sensing period; and a converting circuit configured to generate a plurality of sensing values by amplifying and analog-to-digital converting on outputs of the plurality of sample-and-hold circuits.
