Knowledge & Support

The viewing angle of an LED display refers to the maximum angle from which a person can view the screen with acceptable brightness, contrast, and color fidelity. Beyond this angle, the image may appear dimmed, distorted, or discolored.

Viewing angle is typically measured in degrees, both horizontally (left to right) and vertically (top to bottom). For example, a display with a 160° horizontal viewing angle means the screen can still be viewed clearly even when the viewer is standing 80° to the left or right of the centerline.

Why Is Viewing Angle Important?

The importance of viewing angle depends on the application scenario:

1.Retail stores & showrooms: Customers may approach from different directions. A wide viewing angle ensures everyone sees the same quality.

2.Stage performances & events: Large audiences seated at various angles need to see clear visuals from every position.

3.Stadiums & outdoor billboards: When displays are mounted high or wide, clear visibility from a wide area is essential.

4.Control rooms & meeting spaces: Uniform viewing from all seats boosts communication efficiency.

If the screen has a narrow viewing angle, people standing off-center will see washed-out colors or even an inverted image, affecting the user experience and brand impression.

How Is Viewing Angle Measured?

Viewing angle is determined through laboratory testing using the luminance and color shift as indicators. A standard benchmark defines the viewing angle as the point where brightness drops to 50% or colors deviate beyond acceptable limits.

Typical viewing angles:

Indoor SMD LED displays: 140° to 160° (H) / 120° to 140° (V)

Outdoor SMD displays: up to 160° / 160°

Older DIP LEDs: Often limited to 100° to 120°, more directional

✅ Tips for Choosing the Right Viewing Angle

For advertising and public displays, look for ≥160° horizontal and vertical viewing angles.

For indoor meetings or control rooms, prioritize uniformity and color accuracy over raw brightness.

Always request sample videos or a demo to evaluate how the screen performs from multiple directions.
