Abstract:
1. A liquid crystal display device having dynamically switching driving modes, comprising: a liquid crystal panel comprising a plurality of data lines and a plurality of liquid crystal capacitors, each liquid crystal capacitor being coupled to one of the data lines; an input interface for generating a scan control signal; an oscillator for generating a predetermined frequency; a control unit, electrically coupled to the oscillator, for outputting a first current control signal when a frequency of the scan control signal is lower than the predetermined frequency, and for generating a second current control signal when the frequency of the scan control signal is greater than the predetermined frequency; and a driving circuit, electrically coupled to the controller, for generating a first bias current to charge the plurality of liquid crystal capacitors based on the first current control signal, for generating a second bias current which is greater than the first bias current based on the second current signal, for enabling a charge recycling function in response to the first current control signal, and for disabling a charge-recycling function in response to the second current control signal, wherein enabling the charge recycling function comprises the steps of:
