Abstract
A display device includes display pixels arranged in a display area of a display panel, infrared light emitting pixels arranged in the display area to alternate with the display pixels, light sensing pixels arranged in the display area to alternate with the infrared light emitting pixels, a display scan driver supplying display scan signals to the display pixels and the infrared light emitting pixels, a light sensing driver sequentially supplying sensing scan signals to the light sensing pixels, and a component detection circuit for analyzing biomarker information using light sensing signals received from the light sensing pixels, which are based on light reflected from an object in front of the display panel.
