Claim 4:
5. The data driving circuit of claim 1, further comprising:
a shift register, a latch, an amplifying unit, and an output buffer unit, wherein, the selecting unit is coupled between the shift register and the latch; the shift register is configured to shift the image signal received and temporarily store the image signal shifted, the selecting unit is configured to receive the image signal from the shift register, and the selecting unit is configured to transmit the image signal to the latch for latching according to a threshold, or invert the image signal and then transmit the image signal inverted to the latch for latching according to the threshold; and the amplifying unit is configured to amplify the image signal or the image signal inverted and then transmit the image signal amplified or the image signal inverted which is amplified to the signal conversion unit, and the output buffer unis is configured to receive the grayscale voltage from the signal conversion unit and amplify the grayscale voltage received.
