本論文將參考應用在超扭轉型（STN）液晶顯示器多線驅動技術（Multi-Line Addressing Technology，MLA）的兩種設計方法，包含行輸出線全電壓驅動方式（Full column-voltage technique）以及行輸出線半電壓驅動方式（Half column-voltage technique），用以設計MLA 3線驅動技術。本論文將比較MLA 3線驅動技術與其他相關灰階顯示之特性技術如圖框頻率控制（FRC）技術、脈波寬度調變（PWM）技術、脈波高度調變（PHM）等技術理論探討與比較。
本論文將針對MLA 3線驅動技術計算部份進行研究，軟體部分使用Altrera Quartus II 分析Alt-Pleshko Technique （APT）定址技術以及MLA 3線驅動技術輸出波形，硬體部分將點亮9 x 9被動型液晶顯示器矩陣，液晶控制信號部分使用Altear APEX發展板進行波形輸出，液晶驅動電壓部分則使用CMOS類比開關輸出液晶顯示器所需要的電壓值，最後針對MLA 3線驅動技術與APT定址技術與另兩種多線驅動技術以及FRC灰階技術應用於MLA 3線驅動法進行討論與比較。

This thesis deals with a driving technique for Super-Twisted Nematic (STN) displays. There are two kinds of designing methods for Multi-Line Addressing Technology（MLA）, including the full voltage driving (Full column-voltage) technique and half voltage driving (Half column-voltage) technique for scanning lines. In this study, for gray-level displaying，the Frame Rate Control（FRC）Technology，Pulse width Modulation（PWM）Technology，and Pulse Height Modulation（PHM）Technology will be investigated.
This thesis will focus on the theoretical calculation and its implementation for 3-line MLA technique. Altrera Quartus II was used to simulate the APT and the 3-line MLA technique. The target hardware was used to drive a 9 x 9 STN liquid crystal display. All of the control signals for the liquid crystal display were implemented in an Altera APEX development board. For the power supply of the liquid crystal display, CMOS switches were used to produce the required working voltage. Alter all, the advantages of the APT driving method and those of the MLA driving methods will be compared in discussion.
