Abstract
An active pen is provided. The active pen includes a first transceiver and a first control circuit. The first transceiver is configured to receive uplink information and send corresponding touch coordinate information, first-type downlink information, and second-type downlink information through at least one data channel. The first control circuit is coupled to the first transceiver. The first control circuit generates the touch coordinate information and multiple downlink information based on the uplink information and classifies the downlink information into the first-type downlink information or the second-type downlink information according to the amount of data and a required transmission frequency thereof. A touch system including the active pen is also provided.
