Tablet for detecting both finger and pointer
暂无分享,去创建一个
PURPOSE: A tablet is provided to sense a touch of the finger in a sensing area for sensing a location of the pointer by providing an antenna substrate structure. CONSTITUTION: A first comparator(41) outputs a voltage difference with an induction power. The induced power is generated by enabling a point to access a first line antennas(11a~11d). A pointer detector(50) outputs a first pointer coordinate by detecting a location of the pointer based on the voltage difference. A touch sensor(60) outputs a first touch coordinate by determining access of a finger based on electrostatic capacity sensed from another end of a first line electrodes(21).
