    Abstract: A display device includes a display panel including a plurality of pixels, a pressure sensor configured to sense pressure applied from outside of the display device, a photosensor configured to detect light, and a processor configured to receive a pressure signal sensed by the pressure sensor in each of a plurality of measurement segments, and a first pulse wave signal sensed by the photosensor in each of the plurality of measurement segments. The processor is further configured to identify at least one of the measurement segments as an abnormal measurement segment, remove a pulse waveform from the first pulse wave signal in the abnormal measurement segment, generate a pulse wave signal by interpolating the pulse waveform, and calculate blood pressure based on the pulse wave signal.

    Abstract: The display device includes: a display panel including pixels emitting light; a pressure sensor sensing a pressure; a photo-sensor sensing light; and a main processor receiving a pressure signal sensed by the pressure sensor and a first pulse wave signal sensed by the photo-sensor. The main processor calculates a first feature point corresponding to a first lowest point, a second feature point corresponding to a highest point, and a third feature point corresponding to a second lowest point in each of cycles of the first pulse wave signal, generates a peak detection signal based on an amplitude corresponding to the second feature point and the pressure signal in a first mode and calculates blood pressure information accordingly, and generates first biometric information by calculating a first ratio between a first section and a second section in a second mode and decides whether it coincides with second biometric information stored.
