 技術摘要 / Our Technology： |
一種畫素陣列充電控制方法及電路系統，其可應用於整合至一顯示裝置，例如為主動式液晶顯示器，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。此畫素陣列充電控制方法及電路系統的特點在於可循序將畫素陣列中之連續複數個畫素列同時開啟為充電致能狀態來進行資料更新之充電程序；其中係首先以一預定順序的畫素列的對應資料電壓值來同時對所有開啟之複數個畫素列進行充電；再接著對其它之畫素列則利用其間之電壓差值來進行微調動作，使得其充電電壓被微調至應有之資料電壓值。此作法可使用較長之充電時間來對各個畫素列進行資料更新動作，但仍可提供快速之掃瞄速率。
A dot-matrix display charging control method and system is proposed, which is designed for integration to a dot-matrix display device, such as a 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 concurrently selecting a number of consecutive pixel rows in the dot-matrix panel for charging all of the pixel rows with the same set of data voltages from a master data row that is intended to be applied to one of the selected pixel rows, and then fine-tuning every other pixel row with a set of differential voltages based on the value differences between the master data row and a slave data row that is intended to be applied to the other pixel row. This feature allows the operation of a dot-matrix display device to use a long charging time for data refresh under a fast scan speed.
