An error detecting system, comprising: a control circuit; and a first error detecting circuit, coupled to the control circuit, configure to detect error of input data. The control circuit controls the first error detecting circuit to use a first setting to detect the error in a first time period, controls the first error detecting circuit to use a second setting to detect the error in a second time period following the first time period, and controls the first error detecting circuit to generate a first detecting result corresponding to the first setting and the second setting after the detection corresponding to the first setting and the second setting are completed.

The present invention provides a protection circuit and related operation control method to enable the PFM circuit when the operating duration of the PFM circuit is not greater than a first threshold, and disables the PFM circuit when a rest duration of the PFM circuit is not greater than a second threshold. The present invention further provides a protection circuit and related operation control method to avoid starting excessive vertical scanning operations within one frame scanning period by masking one of the gate scanning start signal STV, the gate clock signal CKV and the gate discharge signal OEV. The present invention further provides a protection circuit and related operation control method to disable the gate scanning start signal STV when the number of clock cycles is not equal to a target number of clock cycles, which protects the gate driver from overload.

A resistive multi-touch device includes a touch panel, a matrix, a scanning circuit, a first multiplexer, a second multiplexer, and a touch controller. The matrix includes m pairs of first electrodes forming m columns and n pairs of second electrodes forming n rows. The scanning circuit detects which column of first electrodes is touched to generate a first selecting signal and which row of second electrodes is touched to generate a second selecting signal according to a predetermined scanning mode. The first multiplexer selects a first signal of the touched first electrode from signals transmitted on the first electrodes according to first selecting signal. The second multiplexer selects a second signal of the touched second electrode from signals transmitted on the second electrodes according to second selecting signal. The touch controller calculates coordinate value of touched point according to first signal and second signal.
