Abstract:
1. A gray-scale data bit processing method applied in a light-emitting diode driving integrated circuit device, comprising the following steps: (a) dividing original gray-scale data into high-bit data and low-bit data within the light-emitting diode driving integrated circuit device; (b) converting the low-bit data into extra single bits, each extra single bit being added to the high-bit data to form a multi-stack display data which has fewer bits than the original gray scale data; (c) adding each high-bit data with corresponding extra single bit to form a set of multi-stack display data; (d) converting predetermined weight values according to corresponding bit values in the multi-stack display data and accumulating the converted weight values to form a sum of weight values; (e) displaying an identical sum of weight values and illumination of the original gray-scale data by adopting the display data with a higher updating rate.
