此篇論文著重於TFT-LCD顯示器的源極驅動電路,設計一個R,G,B各6位元解析度,包含262144 (26 * 26 * 26)種顏色,並可一次控制8個畫素(R,G,B共24個子畫素)的TFT-LCD源極驅動電路。
此電路可分為數位與類比兩個部份,並對於數位部份與類比部份分開設計。數位部分使用Verilog在ISE的環境下完成,類比部份使用Hspice在TSMC 0.18um 1P6M 3.3V的model下完成。
在1280x1024的解析度下,此源極驅動電路的顯示速度可達到螢幕更新率75Hz以上。
This thesis is emphasized on the source driving circuits of the TFT-LCD display. We design a source driving circuits which includes 262144 colors (R-6bits, G-6bits, B-6bits) and could control 8 pixels (24 sub-pixels [R,G,B]) at a time.

The source driving circuits are divided into two parts, digital circuits and analogy circuits. The digital one is designed by the Verilog in ISE condition, and the analogy one is designed by the Hspice with the TSMC 0.18um 1P6M 3.3V model.

In the resolution of 1280x1024, this source driving circuits could work at the refresh rate above 75Hz.
