Abstract

The invention discloses a touch control device and electronic equipment. The touch control device comprises a touch control module, a first infrared detection module which is arranged on the first edge of the touch control module and capable of emitting a first infrared light signal in the first direction to the surface of the touch control module, and a second infrared detection module arranged on the second edge of the touch control module, wherein the first edge is opposite to the second edge, and the second infrared detection module is capable of emitting a second infrared light signal in the second direction to the surface of the touch control module. When first touch control operation generated by a first touch control body exists in a first area of the surface of the touch control module, the touch control module determines a first shielded area formed due to the fact that the first infrared light signal and the second infrared light signal are shielded by the first touch control body through detection, and determines the first touch control position of a first touch control point, corresponding to the first touch control operation, on the surface of the touch control module based on the first shielded area.
