Abstract
A flicker control circuit of liquid crystal devices (LCDs) includes a main control chip, a low differential voltage regulator (LDO) circuit, a first resistor, a second resistor, and a reset resistor. The main control chip includes an operational voltage input end, a common voltage output end, and a dividing reference voltage input end. The LDO circuit receives a voltage provided by an external power module and generates a dividing reference voltage in accordance with the received voltage. One end of the first resistor connects to the LDO circuit to receive the dividing reference voltage, and the other end of the first resistor connects to the dividing reference voltage input end. The flicker of the LCDs may be reduced such that the display performance of the LCDs may be enhanced.
