Display drive circuit and display apparatus

A display drive circuit, comprising:

• a timing control module;
• a source drive module electrically connected to a plurality of data lines and comprising a first type input terminal and a second type input terminal;
• and
• a polarity selection module comprising a first type output terminal, a second type output terminal, a first input terminal and a second input terminal,
• wherein the first input terminal of the polarity selection module is connected to an output terminal of the timing control module, the second input terminal of the polarity selection module is connected to a polarity reversal signal terminal, the first type output terminal of the polarity selection module is connected to the first type input terminal of the source drive module, the second type output terminal of the polarity selection module is connected to the second type input terminal of the source drive module;
• when the polarity selection module receives a control signal sent from the timing control module and a polarity reversal signal sent from the polarity reversal signal terminal at the same time, the first type output terminal outputs a first control signal, having the same polarity as that of the control signal, to the first type input terminal of the source drive module, and the second type output terminal outputs a second control signal, having an opposite polarity to that of the control signal, to the second type input terminal of the source drive module;
• when the polarity selection module receives only the control signal sent from the timing control module, the first and second type output terminals output the first control signals, having the same polarity as that of the control signal, to the first and second type input terminals of the source drive module, respectively;
• and
• wherein the first control signal and the second control signal both are used to control a polarity of data signals sent from the source drive module to the data lines, the polarity of data signals sent from the source drive module to the data lines under the control of the first control signal is different from the polarity of data signals sent from the source drive module to the data lines under the control of the second control signal,
• wherein the polarity selection module further comprises a phase reversion selector;
• wherein the first input terminal of the polarity selection module is electrically connected to the first type output terminal directly by a lead;
• and
• wherein the first input terminal and the second input terminal of the polarity selection module both are electrically connected to the second type output terminal via the phase reversion selector.
