Abstract: A driving apparatus of a display panel and an operation method are provided. The driving apparatus includes a command interface circuit, a video interface circuit, a built-in self test (BIST) circuit, a multiplex circuit and a driving circuit. The command interface circuit receives a test command including a grayscale parameter. The video interface circuit receives video frame data. The BIST circuit generates test frame data representing a test pattern according to the test command and sets a grayscale of the test pattern according to the grayscale parameter included in the test command. The multiplex circuit selects to output the test frame data in a test mode and selects to output the video frame data in a normal operation mode. The driving circuit drives the display panel to display an image according to the test frame data or the video frame data output from an output terminal of the multiplex circuit.
