Abstract

The present disclosure relates to a smart pen and a display device using the same, in which a reflective light reception rate may be enhanced through a light output structure to increase a code pattern and code information recognition rate of a display panel. According to an embodiment of the disclosure, smart pen comprising a body portion, a pen tip portion formed on one end of the body portion to form a path of light emitted from a light emitting portion in an end direction at one side, a code detector detecting shape data for code patterns by applying light to the pen tip portion and receiving light reflected from a display panel and the pen tip portion, and a code processor generating coordinate data by using the shape data and transmitting the coordinate data to a main processor for driving the display panel.
