Abstract
A signal driving circuit for an active matrix type display device having display pixels arranged in a matrix, comprises a signal waveform correcting circuit receiving an input pixel signal for generating a corrected output pixel signal to the display device, said signal waveform correcting circuit including a delay circuit for generating a delay signal, a difference calculating circuit for calculating a difference signal between the input pixel signal and the delay signal, and a correction circuit for generating the corrected output pixel signal based upon the difference signal and the input pixel signal, wherein a portion of the waveform amplitude of the corrected output pixel signal is formed by adjusting a corresponding portion of the waveform amplitude of the input pixel signal based upon the difference signal.
