Abstract:
A method for driving a matrix-type display device comprising the steps of:(a) sampling an analogue display signal of at least one horizontal scanning period in synchronization with sampling clocks, and supplying the sampled display signal to each pixel electrode row aligned in a horizontal direction among pixels provided in matrix; and(b) sequentially selecting the pixel electrode rows in a vertical direction, one pixel electrode row being selected during one horizontal scanning period, in order to supply the sampled display signal from a signal supplying circuit to the selected pixel electrode row,wherein the sampling clocks are generated by dividing a reference clock with a first division ratio and adding an unequal clock signal to the division result, the unequal clock being generated by dividing the reference clock with a second division ratio, the second division ratio being different from the first division ratio.
