Abstract: An image processing device includes a blender and a display quality enhancer. The blender is configured to receive a plurality of layer data, generate first image data by blending the plurality of layer data, the first image data including a plurality of pixel values corresponding to a screen in a display device, and generate pixel map data including a plurality of pixel identifications (IDs) based on the plurality of layer data, the plurality of layer data representing a plurality of images to be displayed on the screen, the plurality of pixel IDs indicating display quality enhancement algorithms to be applied to the plurality of pixel values. The display quality enhancer is configured to generate second image data including a plurality of display quality enhancement pixel values by applying the display quality enhancement algorithms to the plurality of pixel values based on the first image data and the pixel map data.

Abstract: A display system including a host processor and a display driver integrated circuit may be provided. The host processor may generate a clock signal that swings swinging between a high level and a low level, generate and output a first synchronization signal based on the clock signal, generate a wakeup interrupt by measuring a frame update period of a display panel, generates frame data based on the first synchronization signal by enabling an image providing path based on the wakeup interrupt, and output the frame data for every frame update period. The display driver integrated circuit may receive the first synchronization signal and the frame data from the host processor, and control the display panel such that a frame image corresponding to the frame data is displayed on the display panel based on the first synchronization signal without storing the frame data.
