mutual capacitance造句

• Bringing a finger or conductive stylus near the surface of the sensor changes the local electric field which reduces the mutual capacitance.
• Mutual capacitance allows multi-touch operation where multiple fingers, palms or styli can be accurately tracked at the same time.
• "Self-capacitance " sensors can have the same X-Y grid as mutual capacitance sensors, but the columns and rows operate independently.
• This produces a stronger signal than mutual capacitance sensing, but it is unable to resolve accurately more than one finger, which results in " ghosting ", or misplaced location sensing.
• "' Mutual capacitance "'is intentional or unintentional capacitance that occurs between two charge-holding objects or conductors, in which the current passing through one passes over into the other.
• From this, the mutual capacitance C _ { m } between two objects can be defined by solving for the total charge " Q " and using C _ { m } = Q / V.
• This method has a more neutral effect on resonant frequency : mutual capacitance is doubled ( which if inductance were constant would lower the resonant frequency ), and inductance is halved ( which would raise the resonant frequency without the capacitance change ).
• Here L _ 1, C _ 1 are the inductance and the capacitance of the first circuit, L _ 2, C _ 2 are the inductance and the capacitance of the second circuit, and L _ m, C _ m are mutual inductance and mutual capacitance.
• There are two types of capacitive sensing system : mutual capacitance, where the object ( finger, conductive stylus ) alters the mutual coupling between row and column electrodes, which are scanned sequentially; and self-or absolute capacitance where the object ( such as a finger ) loads the sensor or increases the parasitic capacitance to ground.
