Design And Implementation Of LCD-TV With Chipset Of ZR39140 And PW328B

This paper is devoted to describe the design of a LCD-TV based on ZR39140 and PW328B.The scheme of this TV was to meet the demand of the rapidly-growing TV market in Taiwan.It's convenient to use economy and bring you a high quality audio and video experience.Besides it achieved to receive both analog and digital broadcast. The content in this paper included:(1) The history of TV development and the class of the analog and digital TV are introduced.Via discussing the analog and digital TV working theory,the excellence and shortcoming of them,the inevitability of TV signal digital is talked.Lastly,the key technology and research development in TFT-LCD field are mentioned.The study emphases and the market foreground is laid out.in the paper.(2) The excellence,advanced functions and trait of the chips PW328B and ZR39140 which are used to design TFT-LCD are explained.How to make the whole system work is discussed through the details of the hardware connection and software modules.(3) The parameters and the result of the TFT-LCD TV are validated eligibly by the whole machine debugs and laboratorial recordings.At the same time,the existent problems are pointed out,which we need to improve in the future.The whole system take the latest and most advanced LCD TV tech,such as PW328B and ZR39140 which include many functions and have a good performance, but the system is complicated.Module design method is introduced throughout the software and hardware,and it's good for term cooperation.This TV first time achieved in Taiwan to receive both the analog and digital TV signals,and filled the empty of the market.
