Content presented on a display screen is updated responsive to a user input. Content is retrieved and segmented into bands that are rendered onto the display screen incrementally to provide a visual effect similar to an animation. A band is rendered at a starting location and after a refresh interval passes a subsequent band is rendered at a second starting location. The bands may be rendered until the content is shown on the display screen.

A display driver circuit configured to drive a display panel includes a memory, a decoder, and a controller. The memory stores first data using data from outside of the display driver circuit. The decoder decodes the stored first data. The controller generates compression data using the decoded first data. While an image based on the decoded first data is displayed on the display panel, when second data based on the data from the outside are not stored in the memory after the first data are stored in the memory, the controller controls the decoder such that the decoder does not operate and controls the memory such that the compression data are stored in the memory.
