The paper reviews the phylogeny of the LCD, describes the recent development situation of LCD-TV and several authority investigation institution do its prospective forcast. The research of the switching power supply, future development t rend is given in the paper. Outlines of LCD-TV technology, introduce the sort of topological structure. The BUCK type converter topological structure and the systematical basictheory were put emphasis on; the PFC, the reasons of power factor simply and the core of L6562 were analyzed, emphatically on the application circuit of this core, and account the design parameter of the application circuit. The sort and control mode of PWM, the control core of UC3846 and OB2262 were explained, the application circuit of this core were specific analyzed, practice picture in the real circuit uses oscilloscope were educed and contrastive analysis in this research.
