Touch controller with read-out line

A touch controller, comprising:

• a read-out line comprising at least two cascaded electrical circuit segments, each electrical circuit segment comprising two longitudinal arms, wherein one of the longitudinal arms comprises an electrical component, and a lateral arm comprising means for closing in the presence of means for inputting in their vicinity,
• means for measuring the impedance of the read-out line,
• means for comparing the measured impedance of the read-out line to a preset value corresponding to an allowable value of the impedance of the read-out line.

A method for use by a touch controller, comprising:

• measuring the impedance of a read-out line, the read-out line comprising at least two cascaded electrical circuit segments, each electrical circuit segment comprising two longitudinal arms, wherein one of the longitudinal arms comprises an electrical component, and a lateral arm comprising a switch configured to close in the presence of an object in the vicinity of the switch, and
• comparing the measured impedance of the read-out line to a preset value corresponding to an allowable value of the impedance of the read-out line.

A non-transitory computer-readable medium having a computer program stored thereon, the computer program comprising instructions operable to cause a processor of a touch controller to:

• control an analyzer to measure the impedance of a read-out line, the read-out line comprising at least two cascaded electrical circuit segments each electrical circuit segment comprising two longitudinal arms, wherein one of the longitudinal arms comprises an electrical component, and a lateral arm comprising a switch configured to close in the presence of an object in the vicinity of the switch,
• to compare the measured impedance of the read-out line to a preset value corresponding to an allowable value of the impedance of the read-out line.
