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.
