Abstract

A monolithic integration of the horizontal driver circuit into the LCD substrate is demonstrated. The operation frequency of the TFT driver was elevated up to 10MHz by successful use of the laser-recrystallization technique. The horizontal driver circuit, of which the unit stage is composed of a D-flip flop shift register and 2- stage buffer amplifier, was fabricated on a quartz substrate together with the vertical driver and the active-matrix.
