1. A driver circuit, driving a display panel, the driver circuit comprising:
a display driver circuit drives the display panel to be operated in a first mode or a second mode, wherein in the first mode, different areas of the display panel have different frame rates, and in the second mode, the different areas of the display panel have a same frame rate; and
a touch driver circuit coupled to the display driver circuit, wherein when the touch driver circuit detects a touch event, the display driver circuit drives the display panel to be switched from the first mode to the second mode.
