Abstract: 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.

Abstract: 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.
