Abstract
Provided are a latch and a drive method thereof, a source drive circuit and a display device. The latch includes: a first latch circuit and a second latch circuit; the first latch circuit is connected to a first control signal terminal, a data signal terminal and a transmission node, and is configured to latch a data signal from the data signal terminal at a first latch node and transmit the data signal to the transmission node; and the second latch circuit is connected to the transmission node, a first switch signal terminal, a second switch signal terminal and an output node, and is configured to latch a data signal from the transmission node at a second latch node and output the data signal to the output node; a loop in the second latch circuit is turned off in response to the data signal written to the second latch node.
