The work aims to propose the new thinking of minimalism design, and discuss whether it is possible to overcome the disadvantages of the previous treatment methods of excessive deletion of the texture and light and shadow of the design objects by increasing emotionality, readability and popularity, so as to better experience the inherent beauty of minimalism. From the perspective of the current needs of life, the uncertainty and complexity of the relationship between simplicity and complexity were elaborated through the mobile phone interface design cases. The complexity was consciously reduced to simplicity, so as to carry out a new exploration and reinterpretation of the connotation of minimalism. As an important school in the western modern design in the 1960s, minimalism design continues to be popular today. With the continuous development of social economy, many visual communication design works are misread. Because of the over-simplification, the interpretation information is biased. Through the analysis of the case and the thinking of the future design trend, this work expects more scholars in the industry to discuss the innovation of minimalismdesign.
