Apparatus and method for improving response speed

The present invention relates to a LCD driving apparatus and method, and more particularly, to an improved apparatus and method for improving the response speed, the response speed to eliminate the error caused by the noise of the digital image signal. Improved responsiveness apparatus noise removal means for removing the noise of the current which is input digital video data and the previous digital image data having the same pixel location; And by the difference between the current noise of the digital image data and previous digital image data gradation removal compared with a reference value includes a comparing means for outputting the current, it converts digital image data. According to the invention, the can solve the image distortion, but are not not from an existing response time improved method has none of the immunity to noise, and the dragging of the improvement of the response speed of the LCD video, border Blurring the like to the appropriate level to create, which can reduce the effect.
