Infrared Imaging Crt / Lcd Drive Circuit

This dissertation is a part of a whole infrared thermo image system which can be used in the aiming system of guns. Because the platform that this system will be fixed on is not so big, under this condition, the whole system can' t be so large. Thus as a component of this system, the CRT display part must be complete with a small volume, what' s more , it should possess all kinds of function that a display system should have. Through the market investigation, the same type display driver circuit is not only expensive but also very big and clumsy. Just because of the shortcomings mentioned above, I design this small display driver circuit.This dissertation gives a brief introduction of infrared thermo image equipment including its optical system , its electricity system and its display system. Deeply analyzes the facts that affect the quality of the image. On the basis of that a set of CRT display system is designed and some problems during the experiment are discussed. This set of display system inherits the attribute of the traditional CRT display system, at the same time fully consider the volume and the power assumption . Also in the dissertation some small LCD display system are bring forward, modularized hardware system is successfully finished. In addition, the system design and debug experiences are summarized and analyzed in detail.
