With the development of technology, industries are applying full color LED displays more and more widely. Whether it’s indoor conferences, shopping mall advertisements, hotel banquets, or outdoor concert stage performances, stadiums, and train stations, LED displays play a role in all these applications. We all know that devices such as televisions and computers have different viewing angles at different distances. So, what are the viewing angles of full-color LED screens?
I. Viewing Angle of Full Color LED Screen
- Concept: The viewing angle of an LED display screen is the angle from which viewers can clearly observe the content on the screen from different directions. More precisely, it is the maximum angle deviating from the screen’s normal that allows viewers to clearly see the complete content on the screen without significant distortion in brightness and color.
- Generally, full color LED screen has a viewing angle divided into horizontal and vertical components. The horizontal viewing angle refers to the angle from which the displayed image can still be seen normally from the left or right, relative to the vertical normal. Similarly, the vertical viewing angle refers to the angle from which a good viewing effect can be achieved from above or below the horizontal normal.
- Furthermore, the horizontal and vertical viewing angles of LED displays can differ. For example, Ningshine LED’s NS series has a horizontal and vertical viewing angle of 160°. Viewers can see the screen clearly within a range of 80° to the left and right, or up and down. The SF series, on the other hand, has a viewing angle of 140°/120°. This means the LED display has a maximum horizontal viewing angle of 140° and a vertical viewing angle of 120°.
II. Factors Affecting the Viewing Angle
- LED package Method. The viewing angle is related to the LED package colloid of the LED screen. The refractive index of the LED package colloid determines the scattering angle and propagation direction of light. Advanced encapsulation technology can provide a better viewing angle.
- Viewing distance: Theoretically, the wider the viewing angle, the wider the range that viewers can see. Furthermore, larger full-color LED screens have a wider viewing angle compared to smaller ones.
- Pixel density and brightness. High pixel density means smaller pixel pitch, resulting in a more detailed image. Additionally, the brightness of a full color LED screen may decrease with a wider viewing angle. Due to the wider range of light scattering, the brightness decreases.
III. Application Scenarios of Full Color LED Screens
- Outdoor advertising and stage backdrops. Outdoor advertising screens are typically located on streets, in shopping malls, and on buildings, requiring a wide viewing angle to ensure they are visible to pedestrians and audiences from various angles. Similarly, at seated events like concerts and theater performances, a wide viewing angle allows the audience to see the screen clearly.
- Indoor conference rooms and command centers. In conference rooms, command centers, full color LED screen adopts fixed installation. And viewing angles vary depending on the location. A moderate or wide viewing angle ensures that everyone receives the same information.
- High-altitude LED screens. Full color LED screens that are installed at high-rise buildings or suspended require viewers to look up at a significant angle, thus demanding a high vertical viewing angle.
- Small LED screens. For home theaters, televisions, and small conference rooms, the viewing angle is generally small.
In short, choosing a full color LED screen allows you to select the appropriate screen based on your needs. Furthermore, viewing angle and distance, pixel density, packaging method, and brightness all affect the performance of a full color LED display.
