Touch panel and a control method thereof
A touch panel control method applied to a touch panel including at least one antenna and a touch sensing structure having a plurality of touch sensing elements is provided. In the touch panel control method, a scan signal is transmitted to at least one of the plurality of touch sensing elements, and a sensing signal sensed by at least one of the plurality of touch sensing elements is received. Whether the at least one antenna starts operating is detected by a control sensor, and if so, operation of a first plurality of touch sensing elements of the plurality of touch sensing elements is stopped, wherein each of the first plurality of touch sensing elements overlaps the at least one antenna.
1. A touch panel control method, applied to a touch panel comprising at least one antenna and a touch sensing structure having a plurality of touch sensing elements, wherein the touch sensing elements are divided into a first touch sensing element array and a second touch sensing element array, comprising:
transmitting a scan signal to at least one of the plurality of touch sensing elements;
receiving a sensing signal sensed by at least one of the plurality of touch sensing elements; and
detecting whether the at least one antenna starts operating by a control sensor, and if so, stopping operation of the second touch sensing element array, wherein the second touch sensing element array overlaps the at least one antenna, and the first touch sensing element array does not overlap the at least one antenna.
2. The touch panel control method as claimed in claim 1 , further comprising:
after the operation of the second touch sensing element array is stopped, receiving or transmitting communication signals through the at least one antenna.
3. The touch panel control method as claimed in claim 2 , further comprising:
after the communication signals are received or transmitted through the at least one antenna, determining whether the at least one antenna stops operating, if so, re-activating the operation of the second touch sensing element array, and if not, keeping stopping the operation of the second touch sensing element array.
4. The touch panel control method as claimed in claim 1 , wherein the control sensor is a distance detector for detecting whether a device capable of communicating with the at least one antenna is approaching the at least one antenna, and if so, the at least one antenna starts operating.
5. The touch panel control method as claimed in claim 1 , wherein the control sensor is a power sensor for detecting whether there is a device to communicate with the at least one antenna based on changes in power, and if so, the at least one antenna starts operating.
6. A touch panel, comprising:
a touch sensing structure, comprising a plurality of touch sensing elements, wherein the touch sensing elements are divided into a first touch sensing element array and a second touch sensing element array;
at least one antenna;
a touch panel controller, coupled to the touch sensing structure, transmitting a scan signal to at least one of the plurality of touch sensing elements and receiving a sensing signal sensed by at least one of the plurality of touch sensing elements; and
a control sensor, coupled to the at least one antenna and the touch panel controller, detecting whether the at least one antenna starts operating, wherein when the control sensor detects that the at least one antenna starts operating, the control sensor transmits a control signal to the touch panel controller to make the touch panel controller stop operation of the second touch sensing element array, wherein the second touch sensing element array overlaps the at least one antenna, and the first touch sensing element array does not overlap the at least one antenna.
7. The touch panel as claimed in claim 6 , wherein the control sensor is a distance detector for detecting whether a device capable of communicating with the at least one antenna is approaching the at least one antenna, and if so, the at least one antenna starts operating.
8. The touch panel as claimed in claim 6 , wherein the control sensor is a power sensor for detecting whether there is a device to communicate with the at least one antenna based on changes in power, and if so, the at least one antenna starts operating.
9. The touch panel as claimed in claim 6 , wherein when the at least one antenna starts operating, the touch panel controller stops the operation of the second touch sensing element array and maintains operation of the first touch sensing element array.
