Unanswered Questions
How does the device differentiate between touch and approach of an external object?
The device uses the frequencies of the signals transmitted to the driving electrodes to determine touch or approach, but the exact mechanism of this differentiation is not explained in the abstract.
What is the accuracy of touch detection using this technology?
While the technology is described as detecting touch or approach of an external object, the level of accuracy in touch detection is not specified in the abstract.
Original Abstract Submitted
an input sensing device includes first driving electrodes, second driving electrodes, and sensing electrodes, and a sensing driver that transmits a first driving signal to the first driving electrodes at a first frequency, transmits a second driving signal to the second driving electrodes at a second frequency, and determines a touch or approach of an external object based on sensing signals received from the sensing electrodes. the sensing driver includes analog front-end circuits that separate a sensing signal of the first frequency and a sensing signal of the second frequency that are received from the respective sensing electrodes, and generate digital sensing data based on a result of a recombination of the separated sensing signals.
