Display device

A display device comprising:

• a display panel displaying an image;
• an input sensing layer disposed on the display panel and comprising a plurality of sensing electrodes;
• and
• a sensing controller electrically connected to the input sensing layer and operating in at least one of a first mode and a second mode, wherein
• a position of a first external input applied to the input sensing layer is sensed in the first mode,
• biometric information of a second external input applied to the input sensing layer is measured in the second mode,
• the sensing controller receives an induction signal sensed from the input sensing layer, generates a sensing signal from the induction signal, and converts the sensing signal to a correction sensing signal based on a correction value determined based on parameters of surrounding environment,
• the sensing controller measures the biometric information from the correction sensing signal in the second mode, and
• the parameters include a parameter of temperature of the surrounding environment.
