LED Display Settings

This feature manages the digital display portion of the gauge, controlling the colors and visual effects of both the display area and the individual LED segments.

Overview

LED Display Settings allow developers to customize the digital readout of the gauge by defining the display’s background, border properties, and the appearance of the LED segments (both lit and unlit). This includes properties that control glow intensity and brightness, ensuring the display can mimic an LED look that is both modern and highly legible.


Key Points

Aspect
Details

Display Background Color

Controlled by the DisplayBackColor property to set the LED display’s background.

Display Border

DisplayBorderColor and DisplayBorderWidth properties determine the color and thickness of the display’s border.

LED Segment Colors

SegmentOnColor for active (lit) segments and SegmentOffColor for inactive segments define the LED visual appearance.

LED Visual Effects

SegmentGlowIntensity controls the intensity of the glow on lit segments, while SegmentBrightness adjusts overall LED brightness.


Best Practices

Recommendation
Description

Set Consistent Color Themes

Choose display and segment colors that align with your overall UI theme to create a coherent visual experience.

Adjust Glow and Brightness Carefully

Experiment with SegmentGlowIntensity and SegmentBrightness values within the 0.0 to 1.0 range to achieve the desired LED effect without overdoing it.

Use High-Contrast Colors

To ensure readability, use contrasting colors for the display background and the LED segments, particularly in low-light environments.

Test on Multiple Displays

Verify that the LED display settings look as expected across different screen resolutions and brightness settings.


Common Pitfalls

Pitfall
Explanation

Overly High Glow or Brightness Values

Setting values for SegmentGlowIntensity or SegmentBrightness too high may result in an overly saturated or washed-out appearance.

Inconsistent Color Pairings

Using display and segment colors that do not contrast enough can make the LED readout difficult to read or appear unprofessional.

Ignoring Display Border Settings

Omitting or misconfiguring DisplayBorderWidth and DisplayBorderColor can lead to a display that blends into the gauge background or looks incomplete.

Changing Properties at Runtime Without Redraw

When properties are updated at runtime, ensure the control is invalidated so that the changes are immediately visible.


Usage Scenarios

Scenario
Implementation Details

Standalone Digital Readout

Customize the digital display with a dark background (DisplayBackColor) and a contrasting border (DisplayBorderColor and DisplayBorderWidth) to mimic a classic LED clock.

Alert or Status Indicator

Change the SegmentOnColor dynamically to signal an alert (for example, switching from green to red) while maintaining a consistent SegmentOffColor.

Themed Dashboard Integration

Integrate the gauge into a dashboard by matching the LED display colors with the application’s overall color palette, ensuring visual consistency across the UI.


Real Life Usage Scenarios

Scenario
Example Description

Industrial Control Panels

Use LED Display Settings to mimic traditional industrial gauges where the digital readout is vital for monitoring pressure, temperature, or speed.

Financial Dashboards

Implement a modern LED look to display key performance indicators (KPIs) or stock values in a high-tech, digital format.

Medical Monitoring Systems

Present vital signs such as heart rate or oxygen saturation using a clear, high-contrast LED display that is easily readable in varying lighting conditions.


Troubleshooting Tips

Issue
Troubleshooting Approach

LED Display Appears Faded or Oversaturated

Adjust SegmentBrightness and SegmentGlowIntensity within the 0.0–1.0 range; ensure that the selected colors provide adequate contrast for visibility.

Border Not Appearing Correctly

Verify that DisplayBorderWidth is set to a value greater than 0 and that DisplayBorderColor is properly assigned; call Invalidate() if changes are not shown immediately.

Inconsistent LED Segment Appearance

Ensure that updates to SegmentOnColor and SegmentOffColor are made prior to rendering the control; consider triggering a manual redraw if changes do not appear.


Code Examples and Integration Samples

Example 1: Basic LED Display Setup

// Create a new instance of the gauge
SiticoneGaugeDigital gauge = new SiticoneGaugeDigital();

// Configure the LED display background and border
gauge.DisplayBackColor = Color.Black;
gauge.DisplayBorderColor = Color.FromArgb(60, 60, 70);
gauge.DisplayBorderWidth = 2f;

// Set initial segment colors for a classic red LED appearance
gauge.SegmentOnColor = Color.Red;
gauge.SegmentOffColor = Color.DarkRed;

// Add the gauge control to the form
this.Controls.Add(gauge);
gauge.Location = new Point(10, 10);
gauge.Size = new Size(300, 300);

Example 2: Customizing LED Glow and Brightness

// Configure LED segment glow and brightness
gauge.SegmentGlowIntensity = 0.7f;  // Adjust the intensity of the glow for active segments
gauge.SegmentBrightness = 1.0f;     // Set overall LED brightness

// Optionally, update these properties dynamically based on application logic
// For example, in an event handler to simulate a change in conditions:
void UpdateLEDDisplayVisuals(float newIntensity, float newBrightness)
{
    gauge.SegmentGlowIntensity = newIntensity;
    gauge.SegmentBrightness = newBrightness;
    gauge.ForceRedraw(); // Ensure changes are rendered immediately
}

Example 3: Integrating LED Display Settings with Other Gauge Features

// Set up basic gauge core properties first
gauge.MinValue = 0;
gauge.MaxValue = 100;
gauge.Value = 50;

// Configure LED display properties as above
gauge.DisplayBackColor = Color.Black;
gauge.DisplayBorderColor = Color.Gray;
gauge.DisplayBorderWidth = 3f;
gauge.SegmentOnColor = Color.LimeGreen;
gauge.SegmentOffColor = Color.DarkGreen;
gauge.SegmentGlowIntensity = 0.6f;
gauge.SegmentBrightness = 0.9f;

// Add sections (for example, for critical thresholds)
gauge.ClearSections();
gauge.AddSection(new GaugeSection(70, 100, Color.Red));

// Optionally subscribe to events to update external indicators
gauge.ValueChanged += (s, e) => { Console.WriteLine("Gauge value updated."); };
