Abstract: A touch system is provided. The touch system includes a touch tool and a touch panel. The touch tool provides a downlink signal. The touch panel obtains a first sensing area sensed with the touch tool, and obtains a second sensing area other than the first sensing area according to the downlink signal. The touch panel provides a first uplink signal to the first sensing area, and provides a second uplink signal to the second sensing area. The first uplink signal is different from the second uplink signal. The touch tool generates a calculated uplink signal according to the first uplink signal and the second uplink signal, and provides the downlink signal according to the calculated uplink signal.

Abstract: An active stylus includes a memory; a transmission module; and an active stylus controller, coupled to the memory and the transmission module. The active stylus controller controls the transmission module to periodically transmit a downlink beacon signal and a plurality of downlink signals so as to synchronize timing with a touch panel and transmit information. The downlink beacon signal is composed of a plurality of bit data and includes a preamble, stored in the memory, for synchronizing the timing; a digital data, for transmitting information from the active stylus to the touch panel; and a cyclic redundancy check, for executing an error check or an error correction for data. The touch panel is an in-cell/on-cell organic light-emitting diode (OLED) touch screen or an in-cell/on-cell liquid-crystal display (LCD) touch screen.
