Abstract
A driving chip with a central processing unit interface and a liquid crystal display panel in triangular arrangement are combined to be applied to a display. The central processing unit interface of the driving chip receives image data in strip-shaped arrangement. An image conversion device of the driving chip firstly converts the image data in strip-shaped arrangement to image data in triangular arrangement, and then stores the image data in triangular arrangement in a memory of the driving chip. Finally, a digital/analogue converter of the driving chip converts the image data in triangular arrangement to analogue image data, and outputs the analogue image data to a display panel in triangular arrangement. The space of the memory can be remarkably saved by storing the image data in triangular arrangement rather which replaces the image data in strip-shaped arrangement.
