摘要： A source driver includes a driver unit and a data analysis unit. The driver unit drives a display panel according to a video signal. The data analysis unit, which is coupled to the driver unit, analyzes gray level distribution of the video signal, and the data analysis unit enables or disables a charge sharing function of the driver unit according to an analysis result. As a result, the charge sharing function is enabled optionally during different charge sharing periods, and thus the power consumption in the source driver and the operation temperature of the source driver could be reduced as compared with the prior art.

摘要： An electronic device has a first terminal and a second terminal and includes a control unit, a silicon controlled rectifier (SCR), and a switch unit. The control unit detects a positive pulse signal from the first terminal of the electronic device. When the positive pulse signal is detected by the control unit, the control unit generates a reset pulse after a predetermined time. The SCR has a first anode terminal, a second anode terminal, a first cathode terminal, and a second cathode terminal. The switch unit provides a plurality of transmission paths. When the switch unit receives the reset pulse, the switch unit cuts off the transmission paths, so that the first anode terminal, the second anode terminal, the first cathode terminal, and the second cathode terminal of the SCR are floating.
