Display driver integrated circuit with multiple data paths

摘要

A display driver integrated circuit includes a memory unit configured to store image data received from an external host, an image processing chain unit configured to perform image processing on the image data, a data driver configured to control data lines of a display panel based on the image data, and a data path selection unit configured to selectively activate, based on an operation mode of the display driver integrated circuit, one of a first data path and second data path for the image data. The first data path is formed by sequentially connecting the external host, the memory unit, the image processing chain unit and the data driver. The second data path is formed by sequentially connecting the external host, the image processing chain unit, the memory unit and the data driver.
