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.

IC industry and TFT-LCD industry are two of the most important industries in Taiwan. It took near half a century for IC industry to reach one trillion NT dollars production value, but it only took over a decade for TFT-LCD industry to reach one trillion NT dollars production value. The TFT-LCD industy of Taiwan has overpassed the Japan which was the first country to commercialize the TFT-LCD product and is competing the No.1 position with Korea.

半导体产业及TFT-LCD产业是目前台湾产值超过兆元的主要产业，半导体产业从引进到现在已近半世纪，花了很长的时间产值才破兆，然而TFT-LCD产业只花了十几年就达到兆元的产值，同时产值超过最先商业化LCD产品的日本，并且於韩国争夺第一的位置，但是从个别公司而言台湾的个别厂商规模相对较小，只有友达光电的规模排入世界第三名。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
