| Zusammenfassung: | An embodiment provides a data driver for a display and a sensing circuit thereof, and the sensing circuit comprises: an analog front end circuit which generates an input voltage; a sample-and-hold circuit which stores a first sampling voltage according to the input voltage and generates a second sampling voltage obtained by converting the first sampling voltage; and an amplifier circuit which generates a sensing voltage according to the second sampling voltage.
Un mode de réalisation concerne un pilote de données pour un dispositif d'affichage ainsi qu'un circuit de détection associé, et le circuit de détection comprend : un circuit frontal analogique qui génère une tension d'entrée; un circuit échantillonneur-bloqueur qui stocke une première tension d'échantillonnage en fonction de la tension d'entrée et qui génère une seconde tension d'échantillonnage obtenue en convertissant la première tension d'échantillonnage; et un circuit amplificateur qui génère une tension de détection en fonction de la seconde tension d'échantillonnage.
