Gray scale data bit allocation processing method within a light-emitting diode driving integrated circuit device

摘要

The present invention is related to a gray-scale data bit processing method applied in a driving integrated circuit device of light-emitting diode (LED), and more particularly to a separating and recombining method applied to reduce the bit numbers of data to be processed to indicate the brightness of light-emitting diode, and thus a set of weight values and more updating rates are generated to obtain an identical sum of gray-scale weight values compared to the original one processed at a higher bit numbers of data operation.
