Claim 0:
1. A display apparatus comprising:
a touch panel including a plurality of electrodes having first electrodes and second electrodes; and
a touch driver configured to drive the touch panel,
wherein the touch panel includes the first electrodes extending in a first direction and the second electrodes extending in a second direction intersecting the first direction, the second electrodes overlapping the first electrodes,
wherein the touch driver is configured to drive the touch panel in a normal mode and a biometric information measurement mode,
wherein the touch driver is configured to apply a transmission signal to the first electrodes by shifting the transmission signal for groups each including N first electrodes such that the N first electrodes in a same group simultaneously receive the transmission signal, where N is a positive integer, in the normal mode, and to apply the transmission signal to the first electrodes by shifting the transmission signal for groups each including Q first electrodes such that the Q first electrodes in a same group simultaneously receive the transmission signal, where Q is a positive integer greater than N, in the biometric information measurement mode,
wherein the touch driver is configured to measure biometric information based on a measurement value received from at least one of the first and second electrodes during a sensing period having K frame periods, where K is a positive integer, in the biometric information measurement mode, and
wherein the touch driver applies the transmission signal to the second electrodes by shifting the transmission signal for groups each including Q second electrodes such that the Q second electrodes in a same group simultaneously receive the transmission signal after applying the transmission signal to the first electrodes in the biometric information measurement mode.
