Abstract
A transmitter processing method comprising: when in an all channel mode, do following steps: receiving beacon signals, transmitted by a touch panel, in multiple channels; and switching from the all channel mode to a single channel mode if the beacon signals are received in one channel of the multiple channels; and when in the single channel mode, do following steps: transmitting electrical signals in a time slot after the beacon signals are received; and receiving the beacon signals only in the one channel of the multiple channels.
Claims23
A transmitter, comprising:
- a receiving circuit, configured to receive beacon signals;
- a transmitting circuit, configured to transmit electrical signals to a touch panel which emits the beacon signals;
- and
- a processor, wherein when in an all channel mode, the processor is configured for:
- have the receiving circuit receives the beacon signals in multiple channels;
- and
- switching from the all channel mode to a single channel mode if the receiving circuit receives the beacon signals in one channel of the multiple channels;
- and
- wherein in the signal channel mode, the processor is configured for:
- have the transmitting circuit transmits the electrical signals in a time slot after the beacon signals are received;
- and
- have the receiving circuit receives the beacon signals only in the one channel of the multiple channels.
A touch sensitive processing apparatus, comprising:
- a driving circuit, configured for transmitting beacon signals via multiple touch electrodes of a touch panel;
- a sensing circuit, configured for sensing electrical signals via the multiple touch electrodes;
- and
- a processor, coupled to the driving circuit and the sensing circuit, configured for:
- have the driving circuit transmits the beacon signals in one channel, wherein the beacon signals include a data section denoting information corresponding to multiple time slots of transmitters;
- in each of the time slots after the beacon signals are transmitted, respectively, determining whether a transmitter corresponding the current time slot transmits the electrical signals received by the multiple touch electrodes;
- and
- updating the data section denoting information corresponding to the multiple time slots according to the determination results in each of the time slots.
