In the era of big data, all sectors of society pay more and more attention to data value. Data visualization, as the most effective way to present data value, has been given an important position.The electricity industry has many sources of data, complex dimensions and large scale. It is necessary to present massive data clearly, scientifically and accurately through the visualization system. Therefore, it is very important to establish a set of data visualization large screen product evaluation element model based on user experience to improve user satisfaction. This paper mainly collects the user experience elements of the large screen of electricity industry data through user interviews, and uses the card sorting method to establish the element model, which is convenient to quantify the user experience of the large screen of electricity industry data visualization, and realize scientific evaluation of user experience results.
