摘要 |
A data driving circuit receiving an image signal and applying a data signal based on the image signal to a display panel, the data driving circuit includes a signal generator that generates a horizontal scanning identical signal based on the image signal and a load signal instructing an output of the data signal to the display panel; a signal amplifier that alternately converts a polarity of an offset compensation value from positive to negative and amplifies the image signal based on the offset compensation value; and a controller that counts pulses of the horizontal scanning identical signal and controls the signal amplifier to retain the converted polarity of the offset compensation value until a counted reaches a predetermined reference value. |
