Abstract
A mobile communication terminal 100 has a touch panel unit 150 as an input unit. Touch detection is performed by scanning detection signals from the touch panel unit 150 at a given operation frequency. A radio device 120 performs communication such as cellular communication and reception of broadcast such as digital broadcast. When the radio device 120 performs radio transmission/reception operation, a touch detection processing unit 112 identifies an operation frequency of the touch panel unit 150 that is not interfered by the frequency of radio transmission/reception by the radio device 120 and a touch panel control unit 111 controls the touch panel unit 150 to scan it at that operation frequency.
Claims9
An electronic device comprising a radio device and a touch panel, comprising:
- a radio frequency identifying unit that identifies a radio frequency used by said radio device;
- an operation frequency identifying unit that identifies an operation frequency of said touch panel that does not interfere with at least the radio frequency identified by said radio frequency identifying unit;
- a touch panel drive unit that drives said touch panel at the operation frequency identified by said operation frequency identifying unit;
- a display unit having a switchable display frequency;
- a display frequency identifying unit that identifies a display frequency for said display unit that does not interfere with the radio frequency identified by said radio frequency identifying unit;
- and
- a display control unit that operates said display unit and switches the switchable display frequency of the display unit to the display frequency identified by said display frequency identifying unit,
- wherein said radio frequency identifying unit is configured to re-identify a radio frequency used by said radio device when the radio frequency used by said radio device is a frequency for digital broadcast and a reception state for receiving the digital broadcast is changed, and
- wherein said operation frequency identifying unit identifies said operation frequency as a frequency that does not interfere with the display frequency identified by said display frequency identifying unit.
A non-transitory computer-readable storage medium having recorded therein programs that allow a computer, which controls an electronic device including a radio device, a touch panel, and a display unit with a switchable display frequency, to realize the following functions:
- identifying a radio frequency used by said radio device;
- identifying an operation frequency of said touch panel that does not interfere with at least the identified radio frequency;
- driving said touch panel at the identified operation frequency;
- identifying a display frequency for said display unit that does not interfere with the identified radio frequency;
- switching the switchable display frequency of said display unit to the identified display frequency that does not interfere with the identified radio frequency;
- and
- re-identifying the radio frequency used by said radio device when the radio frequency used by said radio device is a frequency for digital broadcast and a reception state for receiving the digital broadcast is changed,
- wherein the operation frequency of said touch panel is identified in such a manner as not to interfere with either of the identified radio frequency or the identified display frequency.
