Abstract

The invention discloses an input device. The input device comprises a touch control unit and an information processing unit connected with the touch control unit; the touch control unit comprises a touch control signal receiving end which is in contact with a touch control screen terminal and a pressure sensor connected with the touch control signal receiving end; the information processing unit comprises an information transceiving unit, which is used for transmitting touch control information, and a gesture sensor, which is connected with the information transceiving unit to obtain the position information of the input device, and the position information is corrected according to deformation information generated by the contact between the touch control screen terminal and the touch control unit. According to the input device provided by the invention, errors generated by the deformation caused by the contact between a touch control head and a touch control screen can be further considered, the errors can be compensated, and a more flexible compensation form can be preserved for the compensation; and furthermore, an energy conversion circuit can be arranged to maximally bring effect of an orientating sensor into play, so that an optimized engineering design is provided.

Description

technical field [0001] The invention belongs to the field of capacitive stylus, and more specifically relates to an active capacitive stylus. Background technique [0002] The capacitive screen used in the capacitive touch screen is a conductive film with a criss-cross structure formed on a transparent conductive film, and these conductive films can be used as sending electrodes and receiving electrodes. When the stylus touches the screen, it will form a coupling capacitance with both the sending electrode and the receiving electrode, and absorb part of the current from the contact point, thereby causing the signal of the receiving electrode to change. The change of the formed electric field detects the touch position of the touch screen on the capacitive screen, thereby realizing the human-computer interaction function. [0003] With the development of capacitive touch screens, the demand for corresponding capacitive pens is also increasing. At present, the active capaciti...
