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.

Abstract: An electronic device is disclosed that includes a display layer, a display driver, a sensor layer on the display layer, and a sensor driver that drives the sensor layer. The display layer includes a scan line, a data line, an emission control line. The display driver drives the display layer and provides signals to the scan, data, and emission control lines. The sensor layer operates in a first sensing mode driven at a first sensing frequency or in a second sensing mode driven at a second sensing frequency different from the first sensing frequency. When the sensor layer operates in the first sensing mode, the display driver outputs a first emission control signal to the emission control line. When the sensor layer operates in the second sensing mode, the display driver provides the emission control line with a second emission control signal having a second waveform that is different from a first waveform of the first emission control signal.
