Abstract
A display apparatus includes a touch panel including a plurality of electrodes and a touch driver. The touch panel includes first electrodes extending in a first direction and second electrodes extending in a second direction and overlapping the first electrodes. The touch driver is configured to drive the touch panel in a normal mode and a biometric information measurement mode. The touch driver is configured to sequentially apply a transmission signal to the first electrodes by shifting the transmission signal at each group of N electrodes (where N is a positive integer) in the normal mode, and to sequentially apply the transmission signal to the first electrodes by shifting the transmission signal at each group of Q electrodes (where Q is a positive integer greater than N) in the biometric information measurement mode.
