Patent ID: 8552954

Claim:
A liquid crystal display system, comprising: a liquid crystal display panel having a plurality of pixels; a gate driving circuit for controlling output signals of a plurality of scan lines, wherein an output signal of each scan line is used for controlling turning-on and turning-off of a switch coupled to a pixel; a source driving circuit for converting display data into a data voltage, then charging/discharging a corresponding pixel to a voltage corresponding to a gray level according to the data voltage; a timing control circuit coupled to the gate driving circuit for generating and sending an output enable signal to the gate driving circuit, and a latch data signal; and a pixel-charge delay circuit coupled to the timing control circuit and the source driving circuit for generating and sending a new latch data signal to the source driving circuit according to the output enable signal and the latch data signal, the pixel-charge delay circuit comprising: a first flip-flop for generating a first latch data signal according to a positive edge of the latch data signal; a second flip-flop for generating a first output enable signal according to a negative edge of the output enable signal; and an exclusive-OR gate coupled to the first flip-flop and the second flip-flop for generating the new latch data signal according to the first latch data signal and the first output enable signal.
