1. Clearly Define Objectives and Display Content
LED large-screen dashboards are typically used in offices, showrooms, or retail stores, with the goal of displaying sales data at a glance:
KPI Indicators: Total sales, daily sales, number of orders, profit
Trends: Monthly sales trends, daily sales comparison
Categories: Product, region, and channel sales rankings
Visual Effects: Charts, number scrolling, animation effects
⚠️ Note: LED screens are best suited for high readability and concise information; avoid cluttering them with too many complex charts. 2. Data Preparation
Data for LED large screens typically comes from enterprise databases or ERP/CRM systems:
Data Source Connection:
SQL databases (MySQL, SQL Server)
Excel/CSV files (for small-scale scenarios)
API interfaces (for real-time data)
Data Cleaning and Aggregation:
Summarize sales figures, order numbers, etc.
Calculate month-on-month and year-on-year growth
Aggregate by time, region, and product category
Data Formatting:
Convert to JSON or CSV for easy reading by LED control software
Consider interfaces or middleware if real-time refresh is required
3. Choosing Display Technology
There are two main ways to implement LED display dashboards:
Method A: Professional LED Large Screen Control Software
Software examples: NovaStar, LEDvision, P3 control system
Features:
Directly reads Excel, CSV, or databases
Provides chart templates (bar charts, line charts, scrolling numbers)
Supports timed refresh and animation
Applicability: For those who don't want to write code and need quick deployment
Method B: Custom Web Page or Application Projection
Uses HTML5 + JavaScript + visualization libraries (ECharts, Highcharts, D3.js)
The web page or application is displayed full-screen on the LED screen
Features:
Highly customizable, capable of dynamic animations
Supports real-time updates (WebSocket or Ajax)
Deployment:
LED screen connected to a computer or embedded player
Browser runs the web page in full screen
4. Designing the Display Interface
LED screen design principles:
Highlight key information: Large numbers, bright colors
Concise information: KPI + trend + ranking is sufficient
Animation assistance: Scrolling numbers, dynamic bar charts, flashing prompts
Color and contrast:
Bright background → Avoid small, high-contrast text
Red/green indicators for sales fluctuations
Common layout:
----------------------------------------
| Total Sales Today's Sales Orders Profit |
----------------------------------------
| Monthly Trend Line Chart |
----------------------------------------
| Product Sales Ranking Bar Chart |
----------------------------------------
| Regional Heat Map |
----------------------------------------
5. Data Refresh
LED display dashboards usually require real-time or periodic refreshing:
Automatic update of database data every minute/hour
Or real-time WebSocket push of data to the screen
Software automatically renders animations or scrolling numbers
6. Deployment and Operation
Connect the LED screen to a control computer or embedded player.
Set the software for automatic refresh.
Regularly check the data interface and display effect.
Summary
LED Sales Data Dashboard = Define Metrics → Data Preparation → Select Display Solution (Software or Web) → Design Visual Layout → Set Refresh and Animation → Deploy Display
Tip: LED screens emphasize simplicity, intuitiveness, and dynamic display, unlike desktop dashboards which have more complex interactions.
