With the development of TFT/LCD technology, now more and more product is trend to apply a colorful TFT panel instead of old fashioned monochrome panel. In order to make the image smoothly displayed on the TFT panel , or to add some vivid effect such as rotation, sub-menu pop-up, even GIF animation, MCU need to do lots work and software developers takes weeks even months to realize the effect and debug. At this time, the TFT controller can play a very important role here, to release the MCU burden, and reduce software developers boring work.
