Understanding Big Screens: Data Visualization, Storytelling, and Client Requirements

What Is a Big Screen?

A big screen is essentially a subset of data visualization , focusing on presenting data in a way that is easily understood by the human eye.

1.1 What Is Data Visualization?

Data visualization is a technique that transforms raw data into visual forms that are quickly and intuitively understood, emphasizing three core elements: visual readability, data display, and analytical insight.

Large volumes of data are often difficult to grasp without visual aids, so visualizing data helps users recognize patterns and draw conclusions rapidly.

Data visualization is a subset of big‑screen design.

1.2 Characteristics of Big Screens

A big screen is a specific form of data visualization.

Big screens are physically large, often larger than a typical office space.

They display multi‑dimensional data centered around a narrative, serving as a storytelling platform for information systems.

Most big screens share a similar look, with about 90% following a common template.

Why Are Big Screens Needed?

The driving force is the ongoing informationization process, which has moved data from paper to digital storage and now to cloud platforms.

As industries become increasingly digital, stakeholders need compelling visual narratives to showcase system capabilities, performance, and future value.

Imagine presenting safety incident locations on a map rather than a raw data table; the visual impact is far more persuasive.

What Do Clients Expect from a Big Screen?

Clients hire you to create a storytelling tool, not to add friction.

The story should align with the client’s goals, such as demonstrating strength to attract partners or highlighting management capabilities.

Data presented must support the narrative; irrelevant or misleading data can backfire.

All data should be internally consistent and, when necessary, synchronized to avoid discrepancies.

Use multiple dimensions and diverse chart types (pie, bar, line, radar, heatmap, etc.) to make the screen persuasive and engaging.

Ultimately, a well‑designed big screen tells a clear story, avoids unnecessary flash, and delivers real value to both the client and the developer.

Conclusion

Understanding why big screens are needed and how to design them around storytelling principles is essential for creating effective, client‑satisfying visual dashboards.
