    摘要: A touch detection method is used in a touch panel. The touch panel is capacitive touch panel integrated with a display panel. The method includes at least obtaining at least one control signal carrying synchronous information from the display panel. The control signal is used to control the display panel to display an image. The method also includes analyzing the control signal to obtain an interference time period, at which the touch panel is possibly interfered, and generating a trigger signal. A driving voltage signal and a sensing period of the touch panel are controlled according to the trigger signal, so that the sensing period is not overlapped with the interference time period.

    摘要: A signal transmitting circuit is provided for cutting off or outputting at least one driving signal for driving a designated light source. The signal transmitting circuit includes an input differential signaling driver, an output differential amplifier, and a fixed-voltage-level-difference supply device. The input differential signaling driver is for receiving a display signal, and outputting an inverting signal and a non-inverting signal according to the display signal. The output differential amplifier is for receiving the inverting signal and non-inverting signal and outputting or cutting off the driving signal according to the voltage-level difference between the inverting signal and the non-inverting signal. The fixed-voltage-level-difference supply device is for supplying a fixed-voltage-level difference to replace the inverting signal and the non-inverting signal received by the output differential amplifier; therefore the output of the output differential amplifier remains low voltage-level to cut off the output of light with a designated color.
