Abstract
A display drive circuit comprises a timing control module, a source drive module and a polarity selection module. The source drive module is electrically connected to a plurality of data lines. A control signal output from the timing control module is input to the source drive module via the polarity selection module. When the polarity selection module receives only the control signal, the polarity selection module outputs a first control signal, having the same polarity as that of the control signal, to the source drive module. When the polarity selection module receives the control signal and a polarity reversal signal at the same time, the polarity selection module outputs the first control signal, having the same polarity as that of the control signal, and a second control signal, having an opposite polarity to that of the control signal, to the source drive module.
