Abstract
A display panel includes a plurality of pixel circuits; and a sense line. The plurality of pixel circuits includes a touch sensing-adapted pixel circuit including a current-driven element, a drive transistor; a hold capacitor configured to hold a voltage corresponding to a data voltage and a sense capacitor. A capacitance of the sense capacitor varies in response to contact of an object with the current-driven display panel in a vicinity of the touch sensing-adapted pixel circuit. The drive transistor is configured to supply a current to the current-driven element in response to the data voltage and supply a sense current to the sense line in response to the capacitance of the sense capacitor.
