碩士 === 大葉大學 === 電機工程學系碩士在職專班 === 93 === LCD control board combine with LCD module is the LCD Control IC currently in use . This thesis focus on TCOM design which is the interior part of LCD control board and module to make the circuit simplify and become a single chip mode. This thesis propose by using TFT-LCD 3.5 inch control board as a monitor and CPLD(Xilinx XC95288XL) as control center associate with PHILIP SAA7111 video decoder to make NTSC continuous source signal become R . G . B digital signal and through Verilog hand ware language design to save in the W26020A static RAM . IN the sane time , rearrange , calculate and calibrate the data and have the sane monitor size as TFT-LCD control board , after that , construct the TCOM continuous signal wave and show the wave on the TFT-LCD control board . After that procedures , it can not only make the drive circuit become a single chip design but also make the input and output signal continuity and become an efficiency control mode .
