DISPLAY DEVICE AND ITS DRIVING METHOD

Title:

DISPLAY DEVICE AND ITS DRIVING METHOD

Document Type and Number:

WIPO Patent Application WO/1995/007493

Kind Code:

A1

Abstract:

A display device includes a display panel, a scanning circuit portion for supplying scanning signals to scanning lines of the display panel, and a scanning control circuit portion for supplying an n-bit (where n is a positive integer of 2 or more) input numerical value signal and an inverted input numerical value signal of the input numerical value signal. In order to restrict the increase in number of wirings and logic circuit portions with higher miniaturization and increase the yield of manufacture, the scanning circuit portion comprises groups of input wirings to which the input numerical value signal and the inverted input numerical value signal are inputted in each bit, a plurality of logic circuit portions, fewer than scanning lines, for selectively inputting the input numerical value signal and the inverted input numerical value signal, and output distribution means for allowing the output from one logic circuit portion to correspond to at least two scanning lines.
