Abstract:
A source driver apparatus for a display panel includes source drivers and a slew rate controller. Each of the source drivers includes a data latch, a decoder, and an output buffer. The data latch is configured to hold sub-pixel data. The decoder is configured to decode the sub-pixel data held in the data latch to provide a driving signal. The output buffer has an adjustable slew rate and is configured to buffer the driving signal to provide a buffered driving signal. The slew rate controller is configured to analyze the sub-pixel data in the data latch in each of the source drivers and dynamically control the slew rate of the output buffer in each of the source drivers.

Claim (Index 15):
The apparatus of  claim 9 , wherein each of the data latches is further configured to hold new sub-pixel data once per horizontal scanning interval in response to a timing controller,\n wherein the slew rate controller is further configured to determine interval numbers of intervals to which values of sub-pixel data for a next horizontal scanning interval held in adjacent data latches during a current horizontal scanning interval belong and calculate a difference between the interval numbers, wherein the differences comprise first differences each calculated based on R sub-pixel data and G sub-pixel data and second differences each calculated based on B sub-pixel data and G\u2032 sub-pixel data, the first differences constitute a first R/G difference group, and the second differences constitute a first BIG\u2032 difference group, wherein the slew rate controller is further configured to:\n perform histogram analysis on the first R/G difference group to exclude one or more differences having an occurrence frequency lower than or equal to a predetermined occurrence frequency from the first R/G difference group to constitute a second R/G difference group, and \n perform histogram analysis on the first B/G\u2032 difference group to exclude one or more differences having an occurrence frequency lower than or equal to the predetermined occurrence frequency from the first B/G\u2032 difference group to thereby constitute a second B/G\u2032 difference group, and \n wherein the slew rate controller is further configured to:\n select a largest difference from each of the second R/G difference group and the second BIG\u2032 difference group, \n select a maximum difference from the largest differences, and \n determine a bias value (IBIAS) for adjusting the slew rate of each of the output buffers at the next horizontal scanning interval using the maximum difference.
