    Abstract: Provided is an electronic device measuring user's biometric information. The electronic device includes a display module including a display panel, in which a signal transmission region, a peripheral display region adjacent to the signal transmission region, and a main display region spaced apart from the signal transmission region are provided, and a camera module overlapped with the signal transmission region. The display panel includes a plurality of first pixels, which are disposed in a unit region of the main display region, and a plurality of second pixels, which are disposed in a unit region of the peripheral display region. An emission area of green light in the unit region of the first pixels is different from an emission area of green light in the unit region of the second pixels.

    Abstract: A display device includes a display panel, an input sensor, and a controller. The controller is operated in a first mode to sense a position at which a first external input is generated, or in a second mode to measure biometric information with respect to a second external input. The controller senses, in the first mode, the position based on a first mode sensing signal to which a variation in capacitance between a transmission electrode and a reception electrode by the first external input is reflected, the controller compensates, 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 the controller measures, in the second mode, the biometric information based on the compensation sensing signal.
