Abstract:
In the disclosure, a display driver integrated circuit (DDIC) configured to drive a display panel and an electronic apparatus having the DDIC would generate display data to constantly update information displayed on the display panel even when a processor is in a power save mode. The DDIC includes a first input terminal, a memory device, an information rendering unit, an information overlay unit, and a source driver. The first input terminal receives a subscribed signal. The memory device stores a background image. The information rendering unit is coupled to the first input terminal of the DDIC to receive the subscribed signal and renders subscribed information according to the subscribed signal. The information overlay unit receives the subscribed information from the information overlay unit and the background image from the memory device, and accordingly, the display data is generated without obtaining frame data from an external processor.
