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.
