CPC G06F 3/0418 (2013.01) [G06F 3/0446 (2019.05); G06F 3/04166 (2019.05)] | 20 Claims |
1. A display device comprising:
a display panel configured to display an image;
an input sensor disposed on the display panel; and
a controller electrically connected to the input sensor, the input sensor comprising:
a transmission electrode; and
a reception electrode electrically insulated from the transmission electrode, wherein the controller is electrically connected to the transmission and reception electrodes, and wherein the controller is configured to:
transmit a scan signal to the transmission electrode,
sense, when operated in a first mode, a position at which a first external input is generated, and measure, when operated in a second mode, biometric information with respect to a second external input,
sense, when operated in the first mode, the position based on a first mode sensing signal to which a variation in capacitance between the transmission electrode and the reception electrode by the first external input is reflected,
compensate, when operated in the second mode, for a second mode sensing signal to which a variation in capacitance between the transmission electrode and the reception electrode by the second external input is reflected based on a compensation value to generate a compensation sensing signal, and
measure, when operated in the second mode, the biometric information based on the compensation sensing signal.
