摘要:
A semiconductor device includes a touch screen panel including a plurality of hover sensors configured to perform self-capacitance sensing. The semiconductor memory device includes a driver configured to provide a plurality of driving signals to the touch screen panel. The semiconductor memory device includes an encoder configured to encode the plurality of driving signals from the driver and provide the encoded plurality of driving signals to the touch screen panel. The semiconductor memory device includes a sensor configured to sense a hover input from the touch screen panel based on the encoded plurality of driving signals.
摘要:
An operating method of a touch controller includes receiving a plurality of currents through a plurality of channels, respectively, sensing a first current among the plurality of currents and extracting the sensed first current as a first control current and converting a charge corresponding to a difference between the first control current and a second current among the plurality of currents into an output voltage.
