DISPLAY DEVICE AND METHOD FOR OPERATING SAME

Abstract: a display device includes: a display panel including a plurality of pixels; a memory storing one or more instructions; and one or more processors configured to execute the one or more instructions to: change light emission patterns of pixels included in a contact area at which an object contacts the display panel, measure a first reflection pattern at the contact area according to the changed light emission patterns, detect a surface roughness of the object based on the first reflection pattern, estimate a degree of deformation of a transparent layer of the display panel corresponding to the contact between the display panel and the object, measure a second reflection pattern at the contact area, based on the degree of deformation of the transparent layer, and detect a hardness of the object based on the second reflection pattern.
