Patent ID: 7209103

Claim:
A liquid crystal projector comprising: a liquid crystal display device having three liquid crystal display panels and a display control device coupled to said three liquid crystal display panels; and an optical system which projects an image of said liquid crystal display device therefrom; wherein said display control device comprises a first section for receiving an externally supplied video signal, and a second section succeeding said first section and coupled to said three liquid crystal display panels; wherein said first section comprises a circuit which preprocesses said externally supplied video signal and outputs the preprocessed video signal; wherein said second section comprises three circuit systems, and each of said three circuit systems amplifies and converts said preprocessed video signal supplied from said first section into an ac signal, increasing a data rate of said video signal by a factor of two or more and outputs drive pulses for driving a corresponding one of said three liquid crystal display panels; wherein said first section is fabricated on a first substrate, said three circuit systems of said second section are fabricated on three second substrates, respectively, and said first and three second substrates are separated from each other; wherein each of said three second substrates is disposed proximately to a corresponding one of said three liquid crystal display panels; and wherein each of said three second substrates is electrically coupled to said first substrate via a corresponding one of three flexible cables.
