摘要： A touch system, a stylus, a touch device, a touch processing circuit, and an operation method thereof are provided. The stylus includes a holding portion and a first transmission electrode. The first transmission electrode is disposed on the holding portion. When the hand of the user holds the holding portion of the stylus, the first transmission electrode transmits a suppressing report signal. The touch device includes a touch panel to detect a touch event. The touch device detects the suppressing report signal of the first transmission electrode through the touch panel to determine a false touch area of the hand on the touch panel. The touch device ignores the touch event of the false touch area when the hand touches the false touch area by mistake.

摘要： An active stylus and a method performed by the active stylus are provided. The active stylus includes a touch sensor inside. The touch sensor is arranged corresponding to a preset pen-holding region on an outer surface. The touch sensor is insulated from the pen body, when an external operating subject touches the preset pen-holding region and touches a touch panel, an uplink signal transmitted by the touch panel is coupled to the pen body via the external operating subject, as an uplink interference signal. The signal processing unit is for: generating a compensation signal; obtaining a compensated interference signal generated based on the compensation signal and the uplink interference signal; generating an uplink signal to be processed based on the received uplink signal and the compensated interference signal; and obtaining uplink information based on the uplink signal to be processed.

摘要： The disclosure provides a touch display driving apparatus and an operation method thereof. The touch display driving apparatus is configured to drive a touch display panel. The touch display driving apparatus includes a touch sensing circuit configured to output a touch driving signal to a touch sensor array of the touch display panel, and receive touch sensing signals from the touch sensor array. The touch driving signal is configured to scan the touch sensor array at a normal scan rate in a normal touch scanning mode, and scan, in response to a touch event which is determined as occurring in a doze mode, the touch sensor array at a first scan rate in a fast touch scanning mode immediately preceding to the normal touch scanning mode, wherein the first scan rate is greater than the normal scan rate.

摘要： A touch driving device and a touch movement track identification method are provided. The touch driving device includes a touch sensing circuit and a touch control circuit. The touch sensing circuit receives touch sensing signals from a touch sensor array when a touch display screen is operated in a display power saving mode, and generates digital touch sensing data according to the touch sensing signals. The touch control circuit periodically generates touch coordinates according to the digital touch sensing data, identifies whether an input symbol corresponding to a touch movement track formed by the touch coordinates generated consecutively matches a preconfigured symbol, and outputs a matching result to a core processing unit of the electronic device. The touch coordinates are generated when the orientation of the input symbol drawn on the touch display screen is not the same as a screen orientation of the touch display screen.

摘要： Provided is an electronic device including a touch panel, a communication unit, and a processing unit coupled to the touch control panel and the communication unit. The communication unit sends a detection signal and receives a response signal based on the detection signal. The processing unit determines an operation mode of the electronic device based on the response signal. The operation mode includes a first mode and a second mode. An input signal source of the electronic device of the first mode includes a finger. The input signal source of the second mode includes the finger and a stylus. When the response signal includes a pen-tip signal of the stylus and a pen-ring signal of the stylus, the processing unit determines whether to set the operation mode to the second mode according to the numerical relationship between the pen-tip signal and the pen-ring signal.

摘要： A stylus control circuit used to control a stylus includes a positioning signal generator. The positioning signal generator is used to generate a first positioning signal having a first frequency and transmit the first positioning signal to the stylus through a first positioning transmission electrode. Wherein, the first frequency corresponds to a position of the first positioning transmission electrode, and the first positioning signal is a frequency signal without carrying any digital data.
