碩士 === 國立交通大學 === 電子研究所 === 82 === In this thesis a new method called active addressing for driving fast STN-LCD is presented. Active addressing makes possible high contrast, high brightness, and is without loss of resolution. Mathematical descriptions are discussed first to derive the theory of active addressing. A computer simulation program is also developed to verify this new method indeed reduces frame response of fast STN-LCD. In addition, a hardware implementation focused on LCD panel with 255rows and 256 columns is discussed in detail. The advantage of this circuit is that it is fully digital, thus simplifies the design task. The TSMC 0.8um single poly double metal(SPDM) fabricated technology is used. The total size of this chip is about 6100um*6400um. The minimum required operating frequency is 3.932MHz. The total transistor count is about 370 thousands.
