 技術摘要 / Our Technology： |
一種畫素陣列資料更新充電控制方法及電路系統，其可整合至一顯示裝置，例如主動式液晶螢幕顯示器，用以對該顯示裝置上的畫素陣列提供一資料更新之充電控制功能。此畫素陣列資料更新充電控制方法及電路系統的特點在於可於每一次進行畫面資料更新程序時，將新畫面資料和舊畫面資料所對應之資料電壓之間的差值作為一充電電壓來輸出至畫素陣列，令畫素單元現有之資料電壓值受到改變而被調整成新畫面的資料電壓值。此作法可使得各個畫素之新畫面資料的更新不必重新施加整個的充電電壓，而僅需施加其與前一格畫面之間的電壓差值，因此可於更短的時間內即可完成各個畫素單元的充電動作，藉此而提供更為快速之掃瞄速率。
A dot-matrix display data refresh voltage charging control method and system is proposed, which is designed for integration to a dot-matrix display device, such as TFT-LCD (Thin Film Transistor Liquid Crystal Display), for controlling a data-refresh process on the dot-matrix display device. The proposed method and system is characterized by the capability of performing data refresh by comparing for the differences between the currently-displayed pixel values and the new pixel values to be used for data refresh to thereby obtain a set of differential voltages for use to be applied to the pixels for data refresh. This feature allows the data-refresh process to use only a low level of differential voltage rather than the full-level of pixel data voltage for data refresh, thus allowing the data-refresh process to be completed in a reduced shorter time period to provide a fast scan speed.
