Abstract
A driving method for LCD apparatuses allows the dividing-driving method, which is effectual against the residual image phenomenon, or the burning phenomenon, to be applicable to drivers which are provided in the conventional LCD apparatuses of the passive type and are driven by the voltage averaging method. By the method, among voltages inputted to the scanning electrode driving circuit, levels of voltages which are inputted also to the data electrode driving circuit are switched to different levels at fixed timings, while levels of voltages inputted only to the data electrode driving circuit are switched to different levels at fixed timings. With this, waveforms of the signals outputted by the respective driving circuits are adjusted, thereby resulting in that a waveform of a difference signal of the scanning signal and the data signal is adjusted.
