摘要
The present invention relates to an apparatus for correcting nonlinear characteristics of a display device and a method of correcting nonlinear characteristics of a display device for compensating for nonlinear characteristics of a voltage applied to a display device driven by an analog after digitally processing data such as a liquid crystal display (LCD) A memory for outputting the video signal at a predetermined timing; a digital signal processing unit for converting the video signal into a format suitable for the display device; and an analog-to-digital converter And a gamma correction unit for changing a bias according to an input signal to compensate for nonlinear characteristics of the display device,;A first step of converting the input analog video signal into a digital signal and outputting the digital video signal at a predetermined timing; a second step of converting the video signal of the first process into an image format suitable for a display device; A third step of converting the converted data into the analog signal and compensating the nonlinear characteristic of the display device by changing the bias according to the level of the input signal and outputting a signal for operating the liquid crystal panel,
