This paper approaches a novel pyroelectric imaging device. We combined the IR pyroelectric FPAs elements with LCDs elements, and studied the possibility of this test. The study of pyroelectric FPAs is a new, important section of IR FPAs, and the pyroelectric FPAs has important and widely usage, but the display section of the equipment using FPAs is more complicated. Researchers have studied the pyroelectric FPAs deeply, and have made some theory and test progress. With the development of film-making and the high- integrated degree of the amplified circuit, the signal that received by the detector can be amplified to drive the LCDs directly. We used the plane-display property of the LCDs, and made the LCDs as the display element of the pyroelectric FPAs detectors, and mounted the LCDs on the back of the pyroelectric FPAs. The output signal of the amplifier is as an additional electric field of an external one, and the LCDs is modulated by the additional electric field and it can display the heat field of the object than detected by the pyroelectric IR FPAs detectors.
