A touch control device, applied in a touch device with a touch panel, comprising a touch control circuit, coupled to the touch panel, and configured to determine a coordinate position of a tip section of an active stylus pen according to a tip signal from the tip section and a coordinate position of the ring section of the active stylus pen according to the ring signal from the ring section; and a processing circuit, coupled to the touch control circuit and configured to determine a usage scenario according to the coordinate position of the tip section and the coordinate position of the ring section and generate vibration strength setting information corresponding to the determined usage scenario, wherein the vibration strength setting information is provided to the active stylus pen for performing vibration operations.

Touch control device, touch system and vibration control method thereof

A stylus, a touch device, and a touch processing circuit are provided. The stylus includes a holding portion and a first transmission electrode. The first transmission electrode is disposed on the holding portion. The touch device includes a touch panel and a touch processing circuit. The touch processing circuit is coupled to the touch panel. The first transmission electrode transmits a first downlink signal to the touch device. The first downlink signal is used to determine a touch event that the stylus is laid on the touch panel. The touch processing circuit receives at least one first downlink signal from the holding portion of the stylus through the touch panel. The touch processing circuit is configured to determine the touch event that the stylus is laid on the touch panel based on the first downlink signal.

Stylus, touch device, and touch processing circuit

A display panel and an operation method of the display panel are provided. The display panel includes a display area and a frame area. The display area is configured to display an image. During a touch sensing period, the display area and the frame area emit an uplink signal to perform an active stylus touch detection operation.
