A system and method for reducing the intensity output response time of a liquid crystal display is disclosed. A display driver circuit selectively substitutes compensation data words for data words in a data stream, in order to reduce the intensity output rise time of a liquid crystal display. In one embodiment, the display driver circuit includes a buffer and a rise time compensator. The buffer receives and stores a first data word intended to be written to a particular pixel. The rise time compensator, upon receipt of a second data word intended for the same pixel, retrieves the first data word from the buffer, compares the value of the second data word to the value of the first data word, and selectively outputs either the second data word or a compensation data word, depending on the relative values of the first and second data words. If the value of the second data word exceeds the value of the first data word by some predetermined amount, then the compensation data word, having a value greater than the second data word, is substituted for the second data word.
