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 7):
The apparatus of  claim 1 , wherein the data latch in each of the source drivers 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 a first interval number of a first interval to which a value of the sub-pixel data for a current horizontal scanning interval held in the data latch in each of the source drivers belongs and a second interval number of a second interval to which a value of the sub-pixel data for a next horizontal scanning interval held in the respective data latch belongs and calculate a difference between the first and second interval numbers, wherein the differences comprise differences calculated based on plural pieces of R sub-pixel data, differences calculated based on plural pieces of G sub-pixel data and differences calculated based on plural pieces of B sub-pixel data, the differences calculated based on the plural pieces of R sub-pixel data constitute a first R difference group, the differences calculated based on the plural pieces of G sub-pixel data constitute a first G difference group, and the differences calculated based on the plural pieces of B sub-pixel data constitute a first B difference group, wherein the slew rate controller is further configured to:\n perform histogram analysis on the first R 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 difference group to thereby constitute a second R difference group, \n perform histogram analysis on the first G difference group to exclude one or more differences having an occurrence frequency lower than or equal to the predetermined occurrence frequency from the first G difference group to thereby constitute a second G difference group, and \n perform histogram analysis on the first B 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 difference group to thereby constitute a second B difference group, and \n wherein the slew rate controller is further configured to:\n select a largest difference from each of the second R difference group, the second G difference group and the second B difference group, \n select a maximum difference from the largest differences, and \n determine a bias value (IBIAS) for adjusting the slew rate of the output buffer in each of the source drivers at the next horizontal scanning interval using the maximum difference.
