Abstract: A display controller includes a resource controller configured to receive layer information about each of a first layer and a second layer that are output at different times through a display panel during a unit frame. The display controller includes a data input direct memory access (DMA) configured to receive first image data corresponding to the first layer and second image data corresponding to the second layer, and a hardware resource configured to receive the first and second image data from the data input DMA, process the received first and second image data according to the layer information, and generate first layer data of the first layer and second layer data of the second layer. The resource controller is configured to control the data input DMA according to the layer information to determine an order in which the first and second image data are provided to the hardware resource.
