What Is An LED Screen Viewing Angle

With the advancement of science and technology, LED displays are widely used in various fields, such as billboards, stage performances, information release, outdoor media, sports venues, indoor large-scale display solutions, etc. They have many advantages over traditional LCD displays, one of the important advantages being that LED displays have a larger viewing angle. So what is the viewing angle of LED display? This article will lead you to understand an important factor that needs to be considered when choosing an LED display --- the viewing angle of the LED display.

Definition of viewing angle of LED display

Viewing angle, as the name suggests, refers to the angle at which users can clearly observe all content on the screen from different directions. The viewing angle can also be understood as the maximum or minimum angle at which the screen can be seen clearly. And the viewing angle is a reference value. The viewing angle of the full-color LED display includes two indicators: horizontal and vertical. The horizontal viewing angle refers to the vertical normal line of the LED display (the vertical imaginary line in the middle of the LED display). At angles perpendicular to the left and right of the normal line, the human eye can clearly see the display. information displayed. The vertical viewing angle is based on the horizontal normal line of the LED display. At the angles above and below the vertical normal line, the human eye can clearly see the content on the display screen. The viewing angle is usually specified in terms of horizontal and vertical angles. For example, a common specification might be 160 degrees horizontally and 140 degrees vertically. This means that viewers can clearly see the screen from multiple angles (horizontally and vertically).

Why is viewing angle important for LED screens?

It ensures the visibility of the LED screen. The wider viewing angle ensures that the content displayed on the LED screen can be easily and clearly visible to viewers from different positions. So 

this is critical in environments where people may be viewing the screen from different angles or distances.

It provides users with a good user experience. Good viewing angles allow more people to view the screen comfortably without distortion, color cast, or loss of brightness, thereby enhancing the overall user experience.

It can provide better applicability. LED displays with wide viewing angles are versatile and can be used in different occasions, such as indoor and outdoor environments, large event venues, retail spaces, transportation hubs, etc. They can accommodate different viewing distances and angles, making them suitable for a variety of applications.

It reduces the effects of glare or reflections, and the wider viewing angle helps keep on-screen content visible and legible in environments with changing lighting conditions or ambient light sources. It therefore ensures that the screen remains readable even in challenging lighting conditions.

It enhances the perceived value of the content and the information conveyed. For businesses and organizations that use LED screens for advertising, branding or messaging, a high-quality viewing experience has a positive impact on their professionalism and brand image.

What factors affect the viewing angle of LED display?

LED types: LED displays usually use different types of LEDs, such as surface mount type (SMD) LEDs and diode type (DIP) LEDs. Different types of LEDs have differences in optical properties and light-emitting angles, which will affect the viewing angle of the display. Among them, surface-mounted LED lights have a better viewing angle, and the current mainstream LED packaging is also SMD surface-mounted packaging.

Pixel Density: The pixel density of a display, also known as pixel pitch or dot pitch, refers to the distance between adjacent pixels. Smaller pixel pitch generally results in wider viewing angles because the pixels are denser, maintaining clarity when viewed from different angles.

Optical transparency: The transparency or reflectivity of a display affects how it appears to viewers when viewed from different angles. High-quality displays usually have better optical transparency, making the picture quality more stable when the viewing angle changes.

Light source and environmental factors: The light source and lighting conditions of the surrounding environment also have an impact on the viewing angle. In bright environments, the display may require a wider viewing angle to ensure content is clearly visible.

Screen size: The size and proportions of your display may also affect viewing angles. Larger displays typically have wider viewing angles, but may also require higher resolution and pixel density to maintain image quality.

In general, the best viewing angle is a comprehensive consideration of many factors, and you need to determine it based on the specific application scenario, audience needs and display technical characteristics. Therefore, if you have any doubts when choosing an LED display, please contact NSELED's professional sales team to ensure that you choose a display product with good viewing angle characteristics that meet your needs.
