Abstract: A display device includes a display panel configured to display an image. A biometric sensor module is disposed on the display panel. The biometric sensor module is configured to output a first transmission signal having a first frequency to sense fingerprint information in a fingerprint sensing mode. The biometric sensor is also configured to output a second transmission signal having a second frequency that is different from the first frequency to sense skin condition information in a skin measuring mode.

Abstract: A display device including a display panel that displays an image, an input sensor disposed on the display panel, and a readout circuit that receives sensing signals from the input sensor and outputs a moisture level signal, in a skin measurement mode. The readout circuit divides the input sensor into a plurality of blocks, selects a valid sensing block based on the sensing signals from the plurality of blocks, and outputs the moisture level signal based on the sensing signals from the valid sensing block.

Abstract: A display device includes a display panel and an input sensor disposed on the display panel. The input sensor includes a first electrode, a second electrode, and a third electrode. The first electrode includes a first sensing pattern having a first opening defined therein. The second electrode includes a second sensing pattern having a second opening defined therein. The third electrode includes a first sub-sensing pattern disposed in the first opening of the first sensing pattern, and a second sub-sensing pattern disposed in the second opening of the second sensing pattern. The first sub-sensing pattern and the second sub-sensing pattern are electrically connected with each other. The first electrode, the second electrode, and the third electrode are insulated from one another.

Abstract: A display device includes: a display panel to display an image by generating light, a sensor disposed under the display panel to convert a light energy into an electrical energy, a voltage generator connected to the sensor, and a capacitive element connected to the sensor. The electrical energy generated by the sensor is charged in the capacitive element. The sensor senses an object using the light reflected by the object.
