摘要

不同電子紙其畫面的解析度、速度與對比度的規格不同，面板設計者會採用不同的電泳材料與不同解析度的主動式矩陣背板來完成這些不同類型的電子紙設計，然而在不同的設計需求下，面板的電子特性與光學響應曲線也會非常的不一樣，因此一個好的顯示器的時序控制器，必須要提供簡單的方式來修改，因應不同顯示材質與不同背板設計的驅動波形。在本文中，我們提出一個用於主動式矩陣電泳顯示器可編輯的時序控制器。我們會探討驅動波形設計的原理，而且我們的時序控制器使用波寬調變的方式能夠支援各式不同的驅動波形。我們在文中提出的時序控制器其效能也在許多電泳顯示器測試平台上獲得驗證。

To design various electronic papers, the panel designers may adopt different types of electrophoretic materials and active matrix backplanes for resolution, speed, and contrast ratio considerations. The electrical and optical characteristics are quite different under different design requirements so that a good display timing controller should provide an easy way to modify waveforms accordingly. We present a configurable timing controller for active matrix electrophoretic displays (EPD). The design principle of driving waveforms is first discussed and the controller can support all variations of driving waveforms with pulse width modulation. The performance of the controller has been verified by several practical EPD systems.
