More Information
Summary:A position input device includes: a communication circuit receiving slope angle information of a display panel; a code detector detecting a pattern shape image of position code patterns of the display panel by emitting infrared light to the display panel and receiving infrared light reflected from the display panel; a light emitting driver controlling an infrared light emitting operation of the code detector; a slope detector detecting slope angle information of the position input device; and a code processor modulating infrared light emitting characteristics of the code detector or modulating pattern shape image data in response to an arrangement angle information between the display panel and the position input device.
