Common Electrode Driving Module and Liquid Crystal Display Panel

A liquid crystal display panel, comprising:

• a display panel;
• a source driving module, configured to provide a data signal to the display panel;
• a gate driving module, configured to provide a scan signal to the display panel;
• and
• a common electrode driving module, configured to provide a common voltage to the display panel, the common voltage driving module comprising:
• a voltage-division resistor string, configured to receive a voltage source and divide the voltage source to obtain an input voltage;
• a switch selecting unit, electrically connected to the voltage-division resistor string, the switch selecting unit comprising at least one switch, the switch selecting unit being configured to change an voltage level of the input voltage by controlling on/off states of the at least one switch to change a number of resistors contained in the voltage voltage-division resistor string;
• a voltage amplifying unit, configured to amplify the input voltage to generate the common voltage and provide the common voltage to the common electrode;
• and
• a mode switching unit, configured to provide a control signal to the switch selecting unit to control the on/off states of the at least one switch according to a current display mode such that the common voltage corresponding to the current display mode is obtained.
