    Abstract: An electronic pen includes a projector configured to generate a virtual code pattern, a light-emitting unit configured to emit light to a detection area, a light-receiving unit configured to detect light reflected from the detection area, and a code processor configured to control the projector, the light-emitting unit, and the light-receiving unit. The code processor is configured to, when a code pattern is detected in a portion of the detection area, generate the virtual code pattern, which corresponds to a remaining portion of the detection area. The projector is configured to output the virtual code pattern to the remaining portion of the detection area.

    Abstract: A display device includes a display panel. A window is disposed on the display panel. A conductive sheet is disposed beneath the display panel such that the display panel is disposed between the window and the conductive sheet. A pressure sensor is disposed between the display panel and the conductive sheet. The pressure sensor includes a sensing area corresponding to a portion of the pressure sensor. A pressure concentration bump is disposed between the window and the conductive sheet. The pressure concentration bump overlaps the sensing area. The pressure sensor includes a first electrode disposed within the sensing area and a second electrode spaced apart from the first electrode.
