Abstract

An integrated circuit includes a first chip including a digital circuit for processing a digital signal; and a second chip including an analog circuit electrically connected to the digital circuit for processing the digital signal and outputting an analog signal having a voltage higher than a voltage of the digital signal, wherein the first and second chips are distinct from each other.

Description

[0001] This application claims the benefit of Korean Patent Application No. 2005-035735 filed on April 28, 2005, the entire contents of which are incorporated herein by reference. technical field [0002] The present invention relates to integrated circuits, and more particularly to integrated circuits for flat panel displays. Background technique [0003] In general, a liquid crystal display device displays images by controlling light transmittance of the liquid crystal layer by changing an electric field applied to the liquid crystal layer. To this end, the liquid crystal display device includes a liquid crystal display panel in which liquid crystal cells are arranged in a matrix, and a driving circuit for driving the liquid crystal display panel. [0004] figure 1 Shown is a liquid crystal display device according to the prior art. refer to figure 1 , the liquid crystal display device includes a liquid crystal display panel 6 for displaying images, a data carrier tape ...
