Abstract: A display apparatus and driving method are provided. The display apparatus, which operates in a display mode or a sensing mode, includes: a first signal line configured to apply a first driving signal to a pixel circuit during the display mode and to apply a sensing input signal to the pixel circuit during the sensing mode; a second signal line configured to apply a second driving signal to the pixel circuit during the display mode and to transfer a sensing output signal from the pixel circuit during the sensing mode; and a pixel including the pixel circuit, wherein a first current path for image display is formed in the pixel circuit during the display mode, and a second current path, configured to measure a resistance of a pressure resistance layer between the first signal line and the second signal line, is formed in the pixel circuit during the sensing mode.
