The source driver includes a data bus, a plurality of channels, a multiplexer and a plurality of output pads. The channels are connected to the output pads via the multiplexer. Each channel has a latch unit. Data is transmitted on the data bus and stored in the latch units. The source driver is powered by a first supply voltage from the power supply. The method comprises determining whether the first supply voltage is insufficient, and if yes, performing the following steps. First, set the data transmitted on the data bus to be a predetermined value. Then, keep the latch units turned on, thereby the data is sent out from the latch units. Then, keep the multiplexer turned on for outputting a driving voltage based on the data via the output pads."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Source driver and method for restraining noise thereof","description":"The present invention discloses a source driver and a method for restraining noise output by a source driver during power on/off of a power supply.
