Abstract: One embodiment provides a touch driving device for driving a touch panel that generates an auxiliary signal using a voltage source and a resistor, and generates a touch driving signal by combining the auxiliary signal and PWM driving pulses. Such touch driving device may change the voltage level of the voltage source or change the resistance value of the resistor to compensate for the characteristic deviation between channel circuits.

Abstract: The present disclosure provides a touch sensing circuit comprising an analog signal processing circuit configured to receive a plurality of sensing signals having different frequencies from touch electrodes; and a digital signal processing circuit configured to receive output data of the analog signal processing circuit and perform a discrete Fourier transform. In addition, the present disclosure provides a touch sensing circuit comprising the digital signal processing circuit of the touch sensing circuit that separates the plurality of sensing signals through the discrete Fourier transform and allowing a simultaneous sensing of a finger touch and a stylus pen touch.

Abstract: The present disclosure relates to a touch circuit and a touch sensing method. A touch circuit may include a driving circuit configured to transmit a driving signal to a touch electrode, a sensing circuit configured to sense a change in capacitance generated in the touch electrode, and a touch control circuit configured to control a polarity of the driving signal transmitted by the driving circuit. The polarity of the driving signal controlled by the touch control circuit may be determined based on a location of the touch electrode. Touch sensitivity can be improved by differently controlling a polarity of a driving signal transmitted to an adjacent touch electrode.

Abstract: The present invention relates to a wet tissue containing a hot water extract of Coptidis Rhizoma extracted under high temperature and high pressure conditions, or a distillate thereof, and more specifically, to a wet tissue containing a hot water extract of Coptidis Rhizoma obtained by mixing 2,000-8,000 parts by weight of water on the basis of 100 parts by weight of Coptidis Rhizoma and extracting the same under high temperature and high pressure conditions of 120-131° C. and 1.2-2.8 atm, respectively, or a distillate thereof. The wet tissue containing a hot water extract of Coptidis Rhizoma or a distillate thereof shows remarkable antibacterial and fungicidal activities against pathogenic microorganisms existing in the skin and has an excellent inflammation inhibitory effect, and thus can be readily used for cleaning the skin and alleviating various inflammatory diseases.
