The shape of the display control area echoes the contour line of the upper cover. The edge is sharpened, and the overall curved surface features are both rigid and soft, introverted but not abrupt. The design of the display and control area conveys the sense of intelligence. The diagonal cutting design of the base reduces the visual weight, integrates the company logo and the concept of "conversion" of AC to DC inverter technology, highlights the brand image and has a good identification degree.
