Grayscale-databit distribution and processing method for controlling LED, involves converting primary grayscale data into display data with reduced data amount, and displaying images with high updating frequency of display data

摘要

The method involves distributing primary grayscale data in an inner side of an integrated switching device for controlling of a LED in high-bit-data and low-bit-data. The low-bit-data is converted into stacked data with reduced bit number, and display data is produced, while the high-bit-data is added to the stacked data. The primary grayscale data is converted into the display data with reduced data amount, and images with high updating frequency of the display data are displayed, where the sum of a definition value of the grayscale data is restorable through repeated updating.
