The composite thin-film IR image detector consists of pyroelectric, LCD and electronic information processing technique. It can reproduce thermal image directly under the condition of uncooled, room temperature. The pyroelectric film signal charge amplifier and LCDs are its mainly components. It is respectively composed of PVDF (or PVDF- TGS, PVDF-PZT) film, TFT and LC film. The device properties parameter are relatively high level, D(superscript *) approximately 10(superscript 8)cmHz(superscript 1/2)w(superscript -1), NEP approximately 10(superscript -9) W and NETD approximately 10(superscript -1) K. The four units is a IR signal detector and to make a foundation for 32 X 32 units and above of multiunits plane array. It is a novel, convenient thermal detecting device and possesses a quite prospects of development and application.
